Leonardo DiCaprio:
Over the last 250 years
we have, in effect,
2
00:00:38,502 --> 00:00:44,210
conducted the largest
science experiment in history.
3
00:00:44,293 --> 00:00:47,418
Since the advent of
the Industrial Revolution,
4
00:00:47,502 --> 00:00:52,210
we have burned over
1.4 trillion tons of carbon
5
00:00:52,293 --> 00:00:54,460
into the atmosphere.
6
00:00:54,543 --> 00:00:57,752
It has changed life on earth
as we know it,
7
00:00:57,835 --> 00:01:01,543
especially in the Arctic.
8
00:01:01,627 --> 00:01:04,043
The melting of the world's
snow and ice
9
00:01:04,126 --> 00:01:07,251
has now triggered multiple
climate tipping points,
10
00:01:07,335 --> 00:01:11,502
threatening the very existence
of life on earth.
11
00:01:11,585 --> 00:01:16,335
Yet this disturbing future
need not be set in stone.
12
00:01:16,418 --> 00:01:20,335
We have long had alternatives
to fossil fuels.
13
00:01:20,418 --> 00:01:23,585
But more recently,
we have actually discovered
14
00:01:23,669 --> 00:01:26,919
how to pull carbon
out of the atmosphere,
15
00:01:27,001 --> 00:01:31,585
giving us a chance at reversing
climate disruption.
16
00:01:31,669 --> 00:01:35,043
If we are able to reverse
climate change in time,
17
00:01:35,126 --> 00:01:40,210
it would be an unprecedented
achievement in human history.
18
00:01:40,293 --> 00:01:42,585
But the clock is ticking.
19
00:01:42,669 --> 00:01:47,043
Scientists say we must
implement these solutions
immediately.
20
00:01:47,126 --> 00:01:50,251
At this critical turning point,
we must give a voice
21
00:01:50,335 --> 00:01:53,669
to the impartial experts
who have presented us
22
00:01:53,752 --> 00:01:58,210
with the facts they have spent
a lifetime to uncover.
23
00:01:58,293 --> 00:02:00,710
It is their time to be heard.
24
00:02:00,794 --> 00:02:04,835
They are the scientists,
researchers and innovators
25
00:02:04,919 --> 00:02:06,960
who have found the solutions
26
00:02:07,043 --> 00:02:11,669
to preserve the very life
of our shared world.
27
00:02:28,543 --> 00:02:30,460
Jennifer Frances Morse:
There is a couple
different projects
28
00:02:30,543 --> 00:02:33,251
that require manual sampling.
29
00:02:36,835 --> 00:02:40,377
So one of them
is the long-term CO2 record.
30
00:02:43,001 --> 00:02:45,126
And the way it's set up,
you still need a person
31
00:02:45,210 --> 00:02:49,085
to come physically take
the sample every Tuesday.
32
00:02:51,168 --> 00:02:53,877
I'm the person
that gets to go in the Sno-Cat
33
00:02:53,960 --> 00:02:56,418
to take the measurements.
34
00:02:58,502 --> 00:03:00,377
We want to keep that
long-term record going
35
00:03:00,460 --> 00:03:02,251
the way
it's always been taken.
36
00:03:04,377 --> 00:03:07,335
DiCaprio:
Monitoring and tracking what
we're doing to our atmosphere
37
00:03:07,418 --> 00:03:10,251
is a serious
and difficult endeavor.
38
00:03:10,335 --> 00:03:12,085
For the last 50 years,
39
00:03:12,168 --> 00:03:14,794
dedicated researchers
from around the world
40
00:03:14,877 --> 00:03:17,627
travel weekly
to the same locations,
41
00:03:17,710 --> 00:03:20,502
taking samples
of greenhouse gases
42
00:03:20,585 --> 00:03:23,251
that cause climate disruption.
43
00:03:23,335 --> 00:03:27,502
So we're at about 11 and a half
thousand feet at Niwot Ridge
44
00:03:27,585 --> 00:03:30,960
in the front range
of the Rocky Mountains
in Colorado.
45
00:03:31,043 --> 00:03:36,960
And this is NOAA's long-term
CO2 sampling site here.
46
00:03:37,043 --> 00:03:38,794
It's the third longest
in the world.
47
00:03:40,710 --> 00:03:42,627
So, these are the flasks
that we're gonna use
48
00:03:42,710 --> 00:03:45,168
to collect our sample,
made out of glass.
49
00:03:45,251 --> 00:03:50,251
And after we're done today
filling them with air, we'll
ski 'em down to our office,
50
00:03:50,335 --> 00:03:53,502
and then we'll take them down
to NOAA's office in Boulder
where they get analyzed
51
00:03:53,585 --> 00:03:56,377
along with similar flasks
from all over the world.
52
00:03:56,460 --> 00:03:58,835
The reason we do it up here
53
00:03:58,919 --> 00:04:01,377
and a lot of the sampling sites
are high up in the atmosphere
54
00:04:01,460 --> 00:04:03,210
is the air up here
is well mixed
55
00:04:03,293 --> 00:04:06,877
so you're getting a good sample
of the whole atmosphere.
56
00:04:06,960 --> 00:04:08,960
There's the little inlet
on the roof.
57
00:04:09,043 --> 00:04:10,543
When I turn on the pump,
58
00:04:10,627 --> 00:04:14,669
it's gonna suck the air
into these flasks.
59
00:04:14,752 --> 00:04:16,835
This is actually the whole...
60
00:04:16,919 --> 00:04:19,418
carbon cycle
and greenhouse gases,
61
00:04:19,502 --> 00:04:22,502
and CO2 and methane
are the big ones.
62
00:04:24,585 --> 00:04:26,543
When they took the first sample
in 1968,
63
00:04:26,627 --> 00:04:29,543
it measured
322 parts per million.
64
00:04:31,752 --> 00:04:34,960
And now we don't know what
this sample's gonna measure yet,
65
00:04:35,043 --> 00:04:37,960
but it's probably
gonna be around 408.
66
00:04:38,043 --> 00:04:41,085
So, it's a little bit
of an increase.
67
00:04:43,877 --> 00:04:46,752
And now I'm just
putting everything away
68
00:04:46,835 --> 00:04:49,001
and getting it ready
for next week's sample.
69
00:05:04,877 --> 00:05:08,502
Patricia Lang:
One of NOAA's missions
since its inception
70
00:05:08,585 --> 00:05:11,752
was to measure carbon dioxide
in the atmosphere
71
00:05:11,835 --> 00:05:15,168
and other gases
that affect the carbon cycle.
72
00:05:15,251 --> 00:05:17,710
Two samples
are collected every week
73
00:05:17,794 --> 00:05:19,710
from around the globe.
74
00:05:19,794 --> 00:05:23,043
So we're looking to see how
these gases change with time.
75
00:05:23,126 --> 00:05:26,669
And the way to do that is
to continuously collect samples.
76
00:05:28,085 --> 00:05:30,960
Currently, we have
about 60 locations.
77
00:05:31,043 --> 00:05:34,085
Most of the samples
are collected in remote areas
78
00:05:34,168 --> 00:05:37,335
away from population centers.
79
00:05:37,418 --> 00:05:39,335
And we measure them
on this set of instruments
80
00:05:39,418 --> 00:05:42,752
for six gases
that affect the carbon cycle.
81
00:05:42,835 --> 00:05:48,001
Those gases are carbon dioxide,
methane, carbon monoxide,
82
00:05:48,085 --> 00:05:50,960
molecular hydrogen,
nitrous oxide
83
00:05:51,043 --> 00:05:52,543
and sulfur hexafluoride.
84
00:05:52,627 --> 00:05:56,168
This system runs five days
and five nights a week,
85
00:05:56,251 --> 00:05:57,293
24 hours a day.
86
00:05:57,377 --> 00:05:58,794
So what I'm doing right now
87
00:05:58,877 --> 00:06:00,710
is putting the air samples
on the manifold
88
00:06:00,794 --> 00:06:02,543
and start the measurements.
89
00:06:02,627 --> 00:06:04,293
And then I can walk away.
90
00:06:29,377 --> 00:06:33,710
Pieter Tans:
I lead NOAA's Global Greenhouse
Gas Reference Network.
91
00:06:33,794 --> 00:06:36,960
The aim of the Global
Greenhouse Gas Reference Network
92
00:06:37,043 --> 00:06:41,377
is to provide data
that are fully calibrated,
93
00:06:41,460 --> 00:06:44,543
carefully quality controlled
and documented.
94
00:06:44,627 --> 00:06:46,543
Data that will still be
fully credible
95
00:06:46,627 --> 00:06:48,919
a hundred years from now
and longer,
96
00:06:49,001 --> 00:06:53,585
so that as climate change
is happening now
97
00:06:53,669 --> 00:06:55,960
and in the future
over the earth,
98
00:06:56,043 --> 00:06:58,877
there will be information
for scientists
99
00:06:59,001 --> 00:07:01,293
that they
can really trust
100
00:07:01,377 --> 00:07:04,210
so that they can diagnose
what actually happened
101
00:07:04,293 --> 00:07:08,460
and how climate change
actually happens, how it works.
102
00:07:09,627 --> 00:07:12,168
So modern CO2 measurements
103
00:07:12,251 --> 00:07:15,085
were initiated by Dave Keeling,
104
00:07:15,168 --> 00:07:17,877
a description situation
of oceanography.
105
00:07:17,960 --> 00:07:22,752
Around 1956, he started
measuring along the west coast.
106
00:07:22,835 --> 00:07:27,960
He saw that during
mid-afternoon wherever he was,
107
00:07:28,043 --> 00:07:31,794
he found pretty much the same
concentration everywhere.
108
00:07:31,877 --> 00:07:35,460
And so it got into his head
the idea that maybe
109
00:07:35,543 --> 00:07:36,794
there's something
that we can call
110
00:07:36,877 --> 00:07:38,293
a background concentration.
111
00:07:38,377 --> 00:07:40,251
He started
continuous measurements then
112
00:07:40,335 --> 00:07:42,752
at Mauna Loa Island
of Hawaii
113
00:07:42,835 --> 00:07:45,210
and on the coast of Antarctica.
114
00:07:46,752 --> 00:07:49,752
The last ice age
at the end of that glaciation
115
00:07:49,835 --> 00:07:52,502
from 20,000
to 11,000 years ago,
116
00:07:52,585 --> 00:07:55,835
CO2 increased by about 80 ppm
117
00:07:55,919 --> 00:07:58,794
from 200 to 280, roughly.
118
00:07:58,877 --> 00:08:00,460
It was very slow.
119
00:08:00,543 --> 00:08:05,001
It took 6,000 years for CO2
to climb the 80 ppm.
120
00:08:05,085 --> 00:08:06,377
Six thousand years!
121
00:08:08,669 --> 00:08:10,043
In pre-industrial times,
122
00:08:10,126 --> 00:08:11,543
so before 1850,
123
00:08:11,627 --> 00:08:14,251
CO2 was close to 280 ppm.
124
00:08:14,335 --> 00:08:18,418
And now of course
we see 2 ppm per year.
125
00:08:18,502 --> 00:08:23,752
That increase was due 100%
to human activities.
126
00:08:25,502 --> 00:08:27,794
The spike that we now see,
127
00:08:27,877 --> 00:08:32,085
compared to most
geologic history,
128
00:08:32,168 --> 00:08:34,210
I call it an explosion.
129
00:08:35,919 --> 00:08:37,835
( sighs ) It's...
130
00:08:37,919 --> 00:08:42,710
It's like instantaneous
in geologic time scale.
131
00:08:46,377 --> 00:08:48,335
DiCaprio:
Carbon has increased
dramatically
132
00:08:48,418 --> 00:08:50,502
since
the Industrial Revolution.
133
00:08:50,585 --> 00:08:53,293
But what does that
actually mean for all of us?
134
00:08:54,794 --> 00:08:56,669
What we have learned
is that excess carbon
135
00:08:56,752 --> 00:08:59,043
creates climate disruption.
136
00:08:59,126 --> 00:09:02,752
It changes the weather patterns
and life support systems
137
00:09:02,835 --> 00:09:07,210
upon which society
depends to survive.
138
00:09:07,293 --> 00:09:09,043
Thom Hartmann:
We have always known
139
00:09:09,126 --> 00:09:11,919
that there's a toxicity
associated with fossil fuels,
140
00:09:12,001 --> 00:09:14,543
but we'd always thought that
it was basically a toxicity
141
00:09:14,627 --> 00:09:16,043
that would affect humans,
142
00:09:16,126 --> 00:09:19,460
you know,
or other individual life forms.
143
00:09:19,543 --> 00:09:21,669
It's really only in the--
144
00:09:21,752 --> 00:09:23,794
within my lifetime certainly
145
00:09:23,877 --> 00:09:26,377
that it has become
frighteningly apparent
146
00:09:26,460 --> 00:09:28,919
that the accumulation
of carbon in the atmosphere
147
00:09:29,001 --> 00:09:31,168
has caused it to warm up.
148
00:09:31,251 --> 00:09:33,877
This greenhouse effect,
this toxicity,
149
00:09:33,960 --> 00:09:38,418
impacts the life systems
of the planet as a whole.
150
00:09:38,502 --> 00:09:42,126
And, you know, once I got that
back in the mid-90s,
151
00:09:42,210 --> 00:09:43,710
I had to start talking about it
152
00:09:43,794 --> 00:09:45,794
and we've been
talking about it ever since.
153
00:09:50,543 --> 00:09:54,126
Dr. Michael Mann:
When we talk about
dangerous planetary warming,
154
00:09:54,210 --> 00:09:58,794
we're referring to something
akin to a two degree Celsius,
155
00:09:58,877 --> 00:10:01,543
that's about three and a half
degree Fahrenheit
156
00:10:01,627 --> 00:10:04,585
warming of the planet relative
to pre-industrial times.
157
00:10:04,669 --> 00:10:07,585
That is where we start to see
some of the worst
158
00:10:07,669 --> 00:10:11,418
and potentially irreversible
impacts of climate change:
159
00:10:11,502 --> 00:10:13,085
substantial melting
of the ice sheets
160
00:10:13,168 --> 00:10:16,752
and associated substantial rise
in sea level,
161
00:10:16,835 --> 00:10:19,251
permanent droughts
in mid-latitudes,
162
00:10:19,335 --> 00:10:22,752
and the list goes on.
163
00:10:22,835 --> 00:10:26,752
Well, catastrophic would be
we melt the major ice sheets,
164
00:10:26,835 --> 00:10:29,627
the Greenland ice sheet
and the West Antarctic ice sheet
165
00:10:29,710 --> 00:10:34,627
as all the major coastal cities
of the world are flooded.
166
00:10:34,710 --> 00:10:36,460
You've got less land.
167
00:10:36,543 --> 00:10:38,418
You've got
environmental refugees,
168
00:10:38,502 --> 00:10:40,960
some people
leaving those regions.
169
00:10:41,043 --> 00:10:43,502
People leaving the tropics
because it's getting too hot
170
00:10:43,585 --> 00:10:45,460
for human habitation.
171
00:10:45,543 --> 00:10:48,418
It's getting too hot
for agriculture.
172
00:10:48,502 --> 00:10:52,043
Crops in the tropics
will decrease dramatically
173
00:10:52,126 --> 00:10:53,794
in their productivity.
174
00:10:53,877 --> 00:10:57,627
In short, you're looking
at a world with less land,
175
00:10:57,710 --> 00:11:01,460
less food, less water
and more people.
176
00:11:01,543 --> 00:11:05,877
And that's a recipe for
a national security disaster.
177
00:11:19,377 --> 00:11:20,835
Jim White:
I work on the carbon cycle,
178
00:11:20,919 --> 00:11:24,794
tasks that I've taken on
for more than 30 years
179
00:11:24,877 --> 00:11:26,669
and truth be told,
I figured
180
00:11:26,752 --> 00:11:29,835
we would have done something
about this 20 years ago
181
00:11:29,919 --> 00:11:31,293
and I could be off
doing something else,
182
00:11:31,377 --> 00:11:33,126
but I'm still doing
what I'm doing.
183
00:11:36,085 --> 00:11:37,752
If you think about
the relationship
184
00:11:37,835 --> 00:11:39,669
between carbon dioxide
and sea level,
185
00:11:39,752 --> 00:11:42,669
there's a couple of interesting
points in that relationship.
186
00:11:42,752 --> 00:11:47,585
One of them is when CO2
goes up to roughly
400 parts per million.
187
00:11:47,669 --> 00:11:52,335
That is warm enough that we
melt off chunks of Antarctica,
188
00:11:52,418 --> 00:11:54,085
chunks of Greenland.
189
00:11:54,168 --> 00:11:56,168
And those chunks
are the chunks that are
190
00:11:56,251 --> 00:11:57,752
what we call marine base.
191
00:11:57,835 --> 00:12:00,126
So the base of the ice sheet
in West Antarctica
192
00:12:00,210 --> 00:12:03,418
is below sea level because
it's pinned to the sediments.
193
00:12:03,502 --> 00:12:04,835
And once it starts to melt,
194
00:12:04,919 --> 00:12:06,502
it's one of these
freight trains.
195
00:12:06,585 --> 00:12:08,752
We don't know how this thing
is gonna stop.
196
00:12:10,377 --> 00:12:14,168
And we're dangerously
at that point right now.
197
00:12:17,377 --> 00:12:18,960
The other threshold
is somewhere around
198
00:12:19,043 --> 00:12:22,126
six to seven hundred
parts per million CO2.
199
00:12:22,210 --> 00:12:25,835
That's warm enough
that there is no more ice,
200
00:12:25,919 --> 00:12:27,418
land ice on the planet.
201
00:12:27,502 --> 00:12:31,126
And you have about
80 meters higher sea level.
202
00:12:33,251 --> 00:12:35,251
We are on our way
203
00:12:35,335 --> 00:12:38,126
to six, seven hundred
parts per million.
204
00:12:41,085 --> 00:12:44,502
But I think that's one of those
interesting threshold moments
205
00:12:44,585 --> 00:12:48,043
in our relationship
with the planet where,
206
00:12:48,126 --> 00:12:52,085
are we gonna push
the climate system
207
00:12:52,168 --> 00:12:54,502
so far out of balance
208
00:12:54,585 --> 00:12:58,460
that we threaten the melting
of all land ice?
209
00:13:09,627 --> 00:13:11,251
Guomundur Ingi Guobrandsson:
Yeah, it has changed.
210
00:13:11,335 --> 00:13:14,168
Icelandic nature
is experiencing change
211
00:13:14,251 --> 00:13:15,960
because of climate change.
212
00:13:16,043 --> 00:13:19,627
This is quite visible in
the south coast, for example.
213
00:13:19,710 --> 00:13:22,752
Our largest glacier,
Glacier Vatnajokull
214
00:13:22,835 --> 00:13:25,960
or Water Glacier
if you translate it directly,
215
00:13:26,043 --> 00:13:28,460
has also retreated quite a lot.
216
00:13:28,543 --> 00:13:31,543
There is one
very interesting observation
217
00:13:31,627 --> 00:13:35,960
that everybody noticed when
they drive the south coast now
218
00:13:36,043 --> 00:13:39,460
and that is that they drive over
the longest bridge in Iceland,
219
00:13:39,543 --> 00:13:41,585
almost one kilometer in length,
220
00:13:41,669 --> 00:13:44,794
and there is
almost no water under it.
221
00:13:44,877 --> 00:13:49,919
So you think, OK,
why building such a big bridge
222
00:13:50,001 --> 00:13:51,710
for almost no water?
223
00:13:53,919 --> 00:13:57,877
Well, this is
just climate change.
224
00:13:57,960 --> 00:14:00,460
The river changed its course
225
00:14:00,543 --> 00:14:03,710
is because of the retreat
of the glacier.
226
00:14:06,585 --> 00:14:11,251
So now we have
this sort of monument,
227
00:14:11,335 --> 00:14:15,043
a symbolic thing of the past.
228
00:14:29,418 --> 00:14:34,669
DiCaprio:
The Arctic is a profoundly
different place right now.
229
00:14:34,752 --> 00:14:38,377
In the Arctic,
the impacts of climate change
230
00:14:38,460 --> 00:14:40,877
are the most extreme.
231
00:14:40,960 --> 00:14:44,794
What scientists are finding is
that what happens in the Arctic
232
00:14:44,877 --> 00:14:49,043
has major impacts
for the rest of the planet.
233
00:14:49,126 --> 00:14:51,794
Catherine Lund Myhre:
I am working with measuring
greenhouse gases
234
00:14:51,877 --> 00:14:53,377
at the Arctic location
235
00:14:53,460 --> 00:14:55,710
and understanding how
the greenhouse gases
236
00:14:55,794 --> 00:14:58,001
are changing over time.
237
00:14:58,085 --> 00:15:01,418
I am concerned about
the increase of temperature
in the Arctic
238
00:15:01,502 --> 00:15:05,919
and the impact this might have
on all the Arctic systems.
239
00:15:06,001 --> 00:15:08,960
But what I think is extremely
important to be aware of
240
00:15:09,043 --> 00:15:13,543
is that with the
sea ice reduction we have now
241
00:15:13,627 --> 00:15:15,251
and all the other changes,
242
00:15:15,335 --> 00:15:17,919
you might change
the whole weather system,
243
00:15:18,001 --> 00:15:19,835
and this has global impact.
244
00:15:21,585 --> 00:15:24,168
We know that the changes
that we see in Arctic
245
00:15:24,251 --> 00:15:27,168
does not only stay
in the Arctic.
246
00:15:30,752 --> 00:15:32,585
Peter Wadhams:
Yeah, I've been
working on sea ice
247
00:15:32,669 --> 00:15:34,377
the last 50 years
pretty much.
248
00:15:34,460 --> 00:15:39,001
And the whole Arctic has changed
so much in that time.
249
00:15:39,085 --> 00:15:43,418
Loss of ice, loss of not only
a loss of area of ice,
250
00:15:43,502 --> 00:15:45,043
but the loss of the appearance
251
00:15:45,126 --> 00:15:47,919
of the great ice fields
of the past
252
00:15:48,001 --> 00:15:51,377
with huge pressure ridges
and very, very thick ice.
253
00:15:51,460 --> 00:15:55,794
Really dramatic ice scenery
has all gone.
254
00:15:58,168 --> 00:16:01,043
Last month I was up
in the Barents Sea
255
00:16:01,126 --> 00:16:03,377
on a research cruise
in a region where
256
00:16:03,460 --> 00:16:06,335
normally you would have
quite a lot of multiyear ice.
257
00:16:06,418 --> 00:16:08,210
We couldn't find
any multiyear ice.
258
00:16:15,210 --> 00:16:19,460
So the ice was all very thin,
30 centimeters thick.
259
00:16:19,543 --> 00:16:22,794
The Arctic Ocean is no longer
a continent of ice
260
00:16:22,877 --> 00:16:25,627
but something that becomes
just water in summer.
261
00:16:25,710 --> 00:16:31,043
There is a real, a huge loss
as far as beauty is concerned,
262
00:16:31,126 --> 00:16:36,085
but also as far as the physics
of how the planet operates.
263
00:16:36,168 --> 00:16:38,960
The ice is disappearing
because the climate's warming,
264
00:16:39,043 --> 00:16:41,293
that's pretty obvious
that will happen,
265
00:16:41,377 --> 00:16:43,669
but there's much more to it
than that,
266
00:16:43,752 --> 00:16:45,585
because in fact
you have
267
00:16:45,669 --> 00:16:48,001
many other
feedback mechanisms going on
268
00:16:48,085 --> 00:16:50,126
which cause the effects
on the planet
269
00:16:50,210 --> 00:16:53,585
to be far worse than just
the retreat of the ice.
270
00:16:56,377 --> 00:16:57,877
So the Arctic's warming up
271
00:16:57,960 --> 00:16:59,919
three times faster
than the rest of the world
272
00:17:00,001 --> 00:17:01,418
and the temperature difference
273
00:17:01,502 --> 00:17:03,877
between the Arctic
and lower latitudes
274
00:17:03,960 --> 00:17:06,210
is getting less,
and that means
275
00:17:06,293 --> 00:17:09,335
that the jet stream
is getting to be weaker.
276
00:17:09,418 --> 00:17:10,877
And as it gets weaker,
277
00:17:10,960 --> 00:17:13,335
it goes from being
almost a straight line
278
00:17:13,418 --> 00:17:19,085
to becoming big lobes
reaching up north and south.
279
00:17:19,168 --> 00:17:20,919
And with it,
when you have a lobe like that,
280
00:17:21,001 --> 00:17:23,251
it means that polar air
can come down
281
00:17:23,335 --> 00:17:27,543
to lower latitudes than it
normally reaches in one sector,
282
00:17:27,627 --> 00:17:30,085
and then in the sector
to the east or west of it,
283
00:17:30,168 --> 00:17:32,669
you've got warm air
going up north
284
00:17:32,752 --> 00:17:34,293
further than it should do.
285
00:17:34,377 --> 00:17:36,710
So you're getting
bizarre weather extremes
286
00:17:36,794 --> 00:17:39,043
which of course everybody's
been commenting on.
287
00:17:39,126 --> 00:17:40,835
The trouble is where
these air masses
288
00:17:40,919 --> 00:17:43,877
are causing
such extreme changes
289
00:17:43,960 --> 00:17:45,669
happens to be the latitudes
290
00:17:45,752 --> 00:17:48,835
at which you have
the maximum food production.
291
00:17:48,919 --> 00:17:50,919
Suddenly our ability
to feed everyone
292
00:17:51,001 --> 00:17:54,835
is being affected
by these polar changes.
293
00:17:56,710 --> 00:17:58,710
You can't take
that amount of ice away
294
00:17:58,794 --> 00:18:01,460
without affecting
so many other things.
295
00:18:13,085 --> 00:18:17,126
DiCaprio:
The impact of our actions
are starting to hit home.
296
00:18:17,210 --> 00:18:19,919
Scientists' predictions
are now coming true
297
00:18:20,001 --> 00:18:21,669
sooner than expected.
298
00:18:21,752 --> 00:18:25,251
We are tragically suffering
through severe storms,
299
00:18:25,335 --> 00:18:28,001
droughts, floods and fires
300
00:18:28,085 --> 00:18:31,043
that are progressively becoming
more intense
301
00:18:31,126 --> 00:18:32,502
and more unpredictable.
302
00:19:16,627 --> 00:19:19,752
Elizabeth Brown:
Fires started
almost simultaneously
303
00:19:19,835 --> 00:19:21,669
in multiple places.
304
00:19:23,502 --> 00:19:27,168
Over 7,000 structures
were destroyed
305
00:19:27,251 --> 00:19:29,293
and about 3,000 homes.
306
00:19:29,377 --> 00:19:32,418
I think at the height
in the early days of the fire,
307
00:19:32,502 --> 00:19:37,919
maybe about 100,000 people
were evacuated.
308
00:19:38,001 --> 00:19:41,418
It's a collective trauma.
309
00:19:43,627 --> 00:19:46,585
Fire Chief Tony Gossner:
Sounded like a war zone,
looked like a war zone.
310
00:19:46,669 --> 00:19:49,460
They talk about
the Hanley Fire,
it took a day to get here.
311
00:19:49,543 --> 00:19:52,335
It burned about
the same footprint,
but it took about a day.
312
00:19:52,418 --> 00:19:54,794
It burned less than
200 structures.
313
00:19:54,877 --> 00:19:56,460
This fire started at night,
314
00:19:56,543 --> 00:19:59,251
made it to Santa Rosa in four,
four and a half hours,
315
00:19:59,335 --> 00:20:02,126
and there's no comparison
other than the footprint.
316
00:20:02,210 --> 00:20:03,585
Cal Fire
Incident Management Team
317
00:20:03,669 --> 00:20:06,251
came here
to help run this incident
318
00:20:06,335 --> 00:20:07,960
and he just shook his head
and said,
319
00:20:08,043 --> 00:20:09,627
"Man, I've never seen
anything like this.
320
00:20:09,710 --> 00:20:11,835
I've been doing this
a long time."
321
00:20:11,960 --> 00:20:14,919
So that's not
terribly comforting,
322
00:20:15,001 --> 00:20:18,877
but that's where we're at
right now.
323
00:20:18,960 --> 00:20:20,460
If we keep having
these wind events,
324
00:20:20,543 --> 00:20:21,960
how do we protect our citizens?
325
00:20:22,043 --> 00:20:23,877
How do we protect
our infrastructure?
326
00:20:23,960 --> 00:20:25,627
What are the things
that we can do
327
00:20:25,710 --> 00:20:28,543
to make it as good as possible?
328
00:20:28,627 --> 00:20:31,877
We've been through four,
five years of drought.
329
00:20:31,960 --> 00:20:35,001
That drought stresses
all the brush, all the trees.
330
00:20:35,085 --> 00:20:39,377
And the winds at Geyser Peak
on one of the weather station
331
00:20:39,460 --> 00:20:42,710
was clocked at
108 miles an hour.
332
00:20:42,794 --> 00:20:44,543
And I don't know what you do
with those kinds of winds.
333
00:20:44,627 --> 00:20:47,043
When something catches on fire,
334
00:20:47,126 --> 00:20:50,043
it's all you can do to try
to figure out where it's going
335
00:20:50,126 --> 00:20:51,752
and how fast
it's gonna get there.
336
00:20:55,168 --> 00:20:56,835
I never would have thought
a fire
337
00:20:56,919 --> 00:21:00,085
would come out of the hills
and run the flats in Santa Rosa.
338
00:21:00,168 --> 00:21:01,168
I really didn't.
339
00:21:03,168 --> 00:21:04,710
Cars were being flipped over.
340
00:21:04,794 --> 00:21:09,377
There were shoebox chunks
of, you know, embers
341
00:21:09,460 --> 00:21:12,794
that were being carried
well ahead of the fire.
342
00:21:12,877 --> 00:21:14,627
You'll see there's some trees
343
00:21:14,710 --> 00:21:16,669
where all the limbs are just,
they're snapped off.
344
00:21:16,752 --> 00:21:18,960
They're not burned off,
they're snapped off.
345
00:21:21,502 --> 00:21:24,794
Brown:
These natural disasters
are so common now
346
00:21:24,877 --> 00:21:28,251
that people know it's gonna
happen to their community.
347
00:21:28,335 --> 00:21:32,752
It's not like a matter of if,
but when.
348
00:21:32,835 --> 00:21:36,043
It is a wake-up call
to everyone
349
00:21:36,126 --> 00:21:38,627
that climate change is here
350
00:21:38,710 --> 00:21:41,418
and that you need
to plan for it.
351
00:21:47,251 --> 00:21:52,418
DiCaprio:
Climate disruption is causing
a rise in extinctions today,
352
00:21:52,502 --> 00:21:55,710
but this isn't the first time.
353
00:21:55,794 --> 00:21:59,543
Scientists studying
geological records have shown
354
00:21:59,627 --> 00:22:03,168
there is a connection
between spikes in carbon
355
00:22:03,251 --> 00:22:06,335
and the past five
mass extinctions.
356
00:22:08,335 --> 00:22:10,251
There is a natural law
357
00:22:10,335 --> 00:22:15,126
that the carbon cycle
affects the fabric of life.
358
00:22:15,210 --> 00:22:18,752
Every time there has been
a massive increase in carbon,
359
00:22:18,835 --> 00:22:24,251
the web of life weakens
and sometimes collapses.
360
00:22:30,001 --> 00:22:34,752
Daniel Rothman:
I've been working on the way
in which the carbon cycle
361
00:22:34,835 --> 00:22:38,168
is associated with the
occurrence of mass extinctions
362
00:22:38,251 --> 00:22:42,919
and whether the carbon cycle
can undergo instabilities
associated with them.
363
00:22:44,585 --> 00:22:47,502
So the carbon cycle
is where life
364
00:22:47,585 --> 00:22:49,710
and the environment interact.
365
00:22:49,794 --> 00:22:53,335
You can think of it
as one grand loop
between photosynthesis,
366
00:22:53,418 --> 00:22:57,335
which is a process
that takes carbon dioxide
out of the atmosphere
367
00:22:57,418 --> 00:23:02,710
and converts it to oxygen
and plant matter
or organic carbon.
368
00:23:02,794 --> 00:23:05,752
And then the back reaction
of the loop we call respiration
369
00:23:05,835 --> 00:23:11,126
which is the process via which
we convert that plant matter
to carbon dioxide.
370
00:23:13,126 --> 00:23:15,877
The grand loop of
the carbon cycle takes about
371
00:23:15,960 --> 00:23:19,960
a hundred gigaton of carbon
out of the atmosphere
and oceans every year
372
00:23:20,043 --> 00:23:21,877
and it returns it each year.
373
00:23:21,960 --> 00:23:23,710
So this is
a hundred gigatons out
374
00:23:23,794 --> 00:23:26,210
and a hundred gigatons back in.
375
00:23:26,293 --> 00:23:30,835
But what we're contributing
is on the order of about 8%
from fossil fuel burning.
376
00:23:30,919 --> 00:23:36,085
It's an 8% increase
compared to what is normally
going back and forth in a year.
377
00:23:36,168 --> 00:23:40,502
It turns out to be
more than what volcanoes
are putting into the system.
378
00:23:52,752 --> 00:23:56,752
Janine Benyus:
The planet is constantly
in the process
379
00:23:56,835 --> 00:24:00,210
of rebalancing its cycles,
like its water cycle
380
00:24:00,293 --> 00:24:02,418
and its nitrogen cycle
and its carbon cycle.
381
00:24:02,502 --> 00:24:06,001
You've gotta think of it
as it's in constant flow.
382
00:24:06,085 --> 00:24:09,168
And part of the planet's
doing that, you know,
383
00:24:09,251 --> 00:24:14,710
was to take all the carbon
that was in the dinosaurs
and land plants
384
00:24:14,794 --> 00:24:20,585
and press that into
eventually oil and fossil fuels.
385
00:24:20,669 --> 00:24:23,585
Over long periods of time
it was sequestered
386
00:24:23,669 --> 00:24:26,794
and we're a young species.
387
00:24:26,877 --> 00:24:31,126
And we were curious
and we dug up the carbon
388
00:24:31,210 --> 00:24:34,710
that had been sequestered
by the earth.
389
00:24:34,794 --> 00:24:38,460
And we burned it,
not knowing it was like
390
00:24:38,543 --> 00:24:43,001
burning furniture in a house
with its windows closed.
391
00:24:44,210 --> 00:24:45,627
So what's happened
392
00:24:45,710 --> 00:24:48,543
is that the planet
is reeling from that.
393
00:24:48,627 --> 00:24:52,960
There's an excess of carbon
up in the atmosphere.
394
00:24:53,043 --> 00:24:58,043
What it's doing is causing
the living conditions
395
00:24:58,126 --> 00:25:01,835
here on earth
to go out of balance.
396
00:25:01,919 --> 00:25:05,877
So as a biologist,
when I look at climate change,
397
00:25:05,960 --> 00:25:11,210
yes, I look at rising seas
and melting polar caps.
398
00:25:11,293 --> 00:25:13,335
Those are evidence for me.
399
00:25:13,418 --> 00:25:18,752
But when we begin to look at
what's happening
400
00:25:18,835 --> 00:25:24,168
to the biological organisms in
response to the warming trends,
401
00:25:24,251 --> 00:25:26,460
they are already on the move.
402
00:25:26,543 --> 00:25:31,001
They're moving towards
the poles to get cooler.
403
00:25:31,085 --> 00:25:35,168
They're moving from
the lower mountains
up in elevation,
404
00:25:35,251 --> 00:25:38,835
meaning their ranges
are moving.
405
00:25:38,919 --> 00:25:43,001
They also sometimes move
without their helpers.
406
00:25:43,085 --> 00:25:46,126
A plant will move north and its
pollinator won't make it.
407
00:25:46,210 --> 00:25:49,210
This is called in our
bloodless language of science,
408
00:25:49,293 --> 00:25:52,835
it's called
ecological disruptions.
409
00:25:54,960 --> 00:25:58,126
So for me, if we change
the very conditions
410
00:25:58,210 --> 00:26:01,210
that gave rise to all of this,
411
00:26:01,293 --> 00:26:05,794
and to us, we--
412
00:26:06,835 --> 00:26:08,460
It's gonna get crazy.
413
00:26:11,627 --> 00:26:13,710
Rothman:
When the carbon cycle
is unstable,
414
00:26:13,794 --> 00:26:18,293
it moves into a realm
that we don't understand.
415
00:26:18,377 --> 00:26:21,210
Going back to geologic time
is that occasionally
416
00:26:21,293 --> 00:26:25,043
there are these essentially
bursts within the carbon cycle
417
00:26:25,126 --> 00:26:26,960
in which things change.
418
00:26:29,919 --> 00:26:31,418
One of them
which is widely known
419
00:26:31,502 --> 00:26:34,251
as the Paleocene Eocene
Thermal Maxima
420
00:26:34,335 --> 00:26:36,168
55 million years ago.
421
00:26:38,293 --> 00:26:41,335
And others
which are decidedly worse.
422
00:26:41,418 --> 00:26:43,085
They're destructive
or catastrophic events.
423
00:26:43,168 --> 00:26:44,710
They're mass extinctions.
424
00:26:44,794 --> 00:26:47,377
The worst of them known as
the Permian Extinction.
425
00:26:50,794 --> 00:26:52,293
So that's the historical record
426
00:26:52,377 --> 00:26:54,210
but what we're doing
to the carbon cycle now
427
00:26:54,293 --> 00:26:55,919
is another kind of problem
428
00:26:56,001 --> 00:26:58,168
because now we know
what's going on.
429
00:26:58,251 --> 00:27:02,543
We know that we have been adding
carbon dioxide
430
00:27:02,627 --> 00:27:04,418
as a consequence
of fossil fuels.
431
00:27:04,502 --> 00:27:06,752
And then the question is,
does that risk
432
00:27:06,835 --> 00:27:09,794
engendering the kind of bursts
that we've seen in the past
433
00:27:09,877 --> 00:27:11,293
that could create
what I would call
434
00:27:11,377 --> 00:27:14,085
an instability
in the carbon cycle?
435
00:27:14,168 --> 00:27:16,877
That is one
in which small changes
436
00:27:16,960 --> 00:27:18,794
become bigger changes.
437
00:27:18,877 --> 00:27:22,543
That's a precise scientists'
definition of catastrophe.
438
00:27:24,043 --> 00:27:26,293
When you get down
to the individual level,
439
00:27:26,377 --> 00:27:29,085
losing one's home to a flood
is a catastrophe.
440
00:28:50,293 --> 00:28:52,168
Mann:
We can still avoid
441
00:28:52,251 --> 00:28:54,710
breaching that dangerous limit
of two degrees,
442
00:28:54,794 --> 00:28:56,210
but if you do the math,
443
00:28:56,293 --> 00:28:58,919
with each passing year
of relative inaction,
444
00:28:59,001 --> 00:29:01,001
it's getting
more and more difficult
445
00:29:01,085 --> 00:29:03,126
to limit our carbon emissions
446
00:29:03,210 --> 00:29:06,752
and remain under
two degrees Celsius warming.
447
00:30:16,752 --> 00:30:20,502
DiCaprio:
We know we have put too much
carbon into the atmosphere.
448
00:30:20,585 --> 00:30:23,210
But how much is too much?
449
00:30:23,293 --> 00:30:26,293
Scientists have figured out
what that amount is
450
00:30:26,377 --> 00:30:28,460
and have created
a carbon budget
451
00:30:28,543 --> 00:30:32,293
that will create
a margin for life.
452
00:30:32,377 --> 00:30:35,126
This budget tells us
where we are now,
453
00:30:35,210 --> 00:30:37,377
how much more carbon
we can burn
454
00:30:37,460 --> 00:30:39,669
and how much
needs to be removed
455
00:30:39,752 --> 00:30:44,085
in order to sustain life
on earth as we know it.
456
00:30:47,752 --> 00:30:49,460
Ottmar Edenhofer:
I would say the major challenge
457
00:30:49,543 --> 00:30:52,543
is indeed
dangerous climate change.
458
00:30:52,627 --> 00:30:56,752
And if we want to avoid
dangerous climate change,
459
00:30:56,835 --> 00:31:00,001
well, then we have to accept
that the atmosphere
460
00:31:00,085 --> 00:31:03,293
is for humankind
a limiting disposal space.
461
00:31:03,377 --> 00:31:08,335
So roughly we can emit
800 gigatons CO2
462
00:31:08,418 --> 00:31:11,710
into the atmosphere in this
limiting disposal space.
463
00:31:11,794 --> 00:31:15,502
And if you take into account
that over the last five years
464
00:31:15,585 --> 00:31:18,377
we have already used
200 gigatons,
465
00:31:18,460 --> 00:31:22,335
so this basically means
that over the next two decades
466
00:31:22,418 --> 00:31:26,543
we have exhausted
the limiting disposal space.
467
00:31:26,627 --> 00:31:29,543
So in Paris
it was very important
468
00:31:29,627 --> 00:31:32,377
that the whole world
and the whole world leaders
469
00:31:32,460 --> 00:31:36,043
agreed on limiting
temperature increase
470
00:31:36,126 --> 00:31:37,877
to well below two degrees.
471
00:31:37,960 --> 00:31:40,210
So that's
the kind of safeguard line
472
00:31:40,293 --> 00:31:41,669
and it's very important that
473
00:31:41,752 --> 00:31:44,460
more than a hundred nations
stand behind it.
474
00:31:44,543 --> 00:31:47,251
So imagine the volume
that is in this ball.
475
00:31:47,335 --> 00:31:49,960
That's a kind of symbol
for the CO2
476
00:31:50,043 --> 00:31:54,251
that is still in the ground
in terms of coal
477
00:31:54,335 --> 00:31:56,877
or in the form of oil and gas.
478
00:31:56,960 --> 00:31:59,835
So this is the amount of carbon.
479
00:31:59,919 --> 00:32:03,126
And if we want
to limit the temperature
480
00:32:03,210 --> 00:32:06,335
to two degrees globally,
we may only emit
481
00:32:06,418 --> 00:32:10,293
this little amount of carbon
into the atmosphere.
482
00:32:10,377 --> 00:32:13,627
And to see that we have
a lot more of carbon
483
00:32:13,710 --> 00:32:17,502
still stored in the ground that
we can emit in the atmosphere
484
00:32:17,585 --> 00:32:20,585
when we want to limit
the temperature to two degrees.
485
00:32:20,669 --> 00:32:23,377
So therefore the question is,
how does it fit together?
486
00:32:23,460 --> 00:32:26,126
So, now for the next 20 years,
487
00:32:26,210 --> 00:32:28,585
this is an enormous
important time span
488
00:32:28,669 --> 00:32:30,627
to transform our economies,
489
00:32:30,710 --> 00:32:34,168
to decouple economic growth
from emission growth.
490
00:32:34,251 --> 00:32:38,377
And by middle of the century,
we need zero emissions,
491
00:32:38,460 --> 00:32:43,460
and after 2050 you need
even negative emissions.
492
00:32:43,543 --> 00:32:46,960
The carbon clock
is just informing people
where we are now.
493
00:32:47,043 --> 00:32:50,251
What is the pathway
how we exhaust
494
00:32:50,335 --> 00:32:53,794
the limiting disposal space
of the atmosphere.
495
00:32:53,877 --> 00:32:56,585
And this is a huge challenge
for humankind.
496
00:33:08,001 --> 00:33:11,293
DiCaprio:
Science tells us that
our current climate crisis
497
00:33:11,377 --> 00:33:14,001
is a problem we've created.
498
00:33:14,085 --> 00:33:17,085
But it is also a problem
we can fix.
499
00:33:17,168 --> 00:33:20,960
Not only do we need
to stop emitting carbon
at the current levels
500
00:33:21,043 --> 00:33:23,377
by switching
to renewable energy,
501
00:33:23,460 --> 00:33:28,627
but it is also critical to pull
carbon out of the atmosphere.
502
00:33:28,710 --> 00:33:34,168
Climate change can be reversed
if we act now.
503
00:33:34,251 --> 00:33:37,335
Recently researchers have
figured out what solutions
504
00:33:37,418 --> 00:33:42,460
can draw carbon down,
getting us back to
pre-industrial levels.
505
00:33:45,585 --> 00:33:48,710
Paul Hawken:
There's only two things you
can do about the atmosphere.
506
00:33:48,794 --> 00:33:51,543
You can either stop putting
greenhouse gases up there
507
00:33:51,627 --> 00:33:54,543
or you can bring CO2 back down.
That's it.
508
00:33:54,627 --> 00:33:56,835
And you can do the first one
by conservation,
509
00:33:56,919 --> 00:33:59,460
energy efficiency
and clean energy.
510
00:33:59,543 --> 00:34:02,085
And the second one through
photosynthesis,
511
00:34:02,168 --> 00:34:06,919
whether it's on land, on farms,
on forests, phytoplankton,
512
00:34:07,001 --> 00:34:09,710
kelp in the oceans; there's only
two things you can do.
513
00:34:09,794 --> 00:34:12,752
So that actually
sorts it pretty simply.
514
00:34:12,835 --> 00:34:17,043
And in the past what has
been done in terms of solutions
515
00:34:17,126 --> 00:34:19,377
is that it's focused on energy.
516
00:34:19,460 --> 00:34:21,335
Energy, energy, energy.
517
00:34:21,418 --> 00:34:23,377
And the reason for that
is understandable.
518
00:34:23,460 --> 00:34:25,168
So it makes perfect sense
to say,
519
00:34:25,251 --> 00:34:28,460
"Well, let's stop putting
that CO2 up there,"
520
00:34:28,543 --> 00:34:32,043
excepting that in the process
of emphasizing clean energy,
521
00:34:32,126 --> 00:34:34,669
renewable energy, solar,
wind, et cetera,
522
00:34:34,752 --> 00:34:39,293
it's sort of occluded
the rest of the solutions.
523
00:34:48,335 --> 00:34:50,335
The purpose of Drawdown
is to see
524
00:34:50,418 --> 00:34:54,085
if the 80 solutions
that we had modeled
525
00:34:54,168 --> 00:34:58,043
would scale to the point where
we could reverse global warming
526
00:34:58,126 --> 00:34:59,877
within 30 years,
527
00:34:59,960 --> 00:35:02,669
going from reduce to reverse.
528
00:35:02,752 --> 00:35:04,335
The bend the carbon curve,
529
00:35:04,418 --> 00:35:07,377
what Drawdown shows,
is that we have choices.
530
00:35:07,460 --> 00:35:12,669
And that if we increase
the rate that we're scaling
some of the solutions,
531
00:35:12,752 --> 00:35:15,794
then we could achieve Drawdown
at 2050.
532
00:35:17,585 --> 00:35:20,585
And if you say
the odds are long,
533
00:35:20,669 --> 00:35:22,960
I agree, they're long odds.
534
00:35:23,043 --> 00:35:24,960
I'll take 'em.
535
00:35:53,502 --> 00:35:55,293
Linwood Gill:
My name is Linwood Gill.
536
00:35:55,377 --> 00:35:58,877
I'm the Chief Forester for the
Usal Redwood Forest Company.
537
00:36:00,210 --> 00:36:03,627
Usal Redwood Forest
is a community forest,
538
00:36:03,710 --> 00:36:07,210
it's owned by a non-profit,
the Redwood Forest Foundation.
539
00:36:07,293 --> 00:36:09,418
It's a 50,000 acre forest
540
00:36:09,502 --> 00:36:13,460
which is dedicated
to managing the forest
541
00:36:13,543 --> 00:36:15,043
on a long-term basis
542
00:36:15,126 --> 00:36:17,502
for the economic stability
of the community,
543
00:36:17,585 --> 00:36:20,752
as well as restoring
the forest habitat,
544
00:36:20,835 --> 00:36:23,335
restoring the fish habitat,
545
00:36:23,418 --> 00:36:25,669
and also for
sequestering carbon.
546
00:36:25,752 --> 00:36:31,669
And carbon sequestration
is a main part of our
operations right now.
547
00:36:31,752 --> 00:36:34,335
Carbon sequestration
is an important part
548
00:36:34,418 --> 00:36:37,001
of combatting climate change.
549
00:36:37,085 --> 00:36:41,168
The Usal Redwood Forest is
a very young redwood forest.
550
00:36:41,251 --> 00:36:44,919
and redwoods can absorb
more carbon
551
00:36:45,001 --> 00:36:47,251
than any other forest type
on the planet.
552
00:36:48,960 --> 00:36:50,460
Redwoods store carbon
553
00:36:50,543 --> 00:36:54,251
by absorbing carbon
from carbon dioxide
554
00:36:54,335 --> 00:36:56,502
out of the air into its needles
555
00:36:56,585 --> 00:36:58,794
and stores it into
the bowl of the tree,
556
00:36:58,877 --> 00:37:02,126
the trunk or the roots,
the branches.
557
00:37:02,210 --> 00:37:03,960
To my knowledge,
558
00:37:04,043 --> 00:37:05,960
this is one of
the largest carbon projects
559
00:37:06,043 --> 00:37:08,001
in the country, yes.
560
00:37:15,460 --> 00:37:18,377
I am the Biochar
Project Manager
561
00:37:18,460 --> 00:37:20,752
for the Redwood Forest
Foundation.
562
00:37:20,835 --> 00:37:24,460
We're sort of at a perfect
storm right now in California
563
00:37:24,543 --> 00:37:28,752
where we have over
a hundred million dead trees
in the Sierra.
564
00:37:28,835 --> 00:37:31,627
And we need to do something
with that.
565
00:37:33,543 --> 00:37:36,210
We have what is called
the western pine bark beetle,
566
00:37:36,293 --> 00:37:41,293
which makes its living by
feeding on ponderosa pine,
and other trees as well.
567
00:37:43,043 --> 00:37:45,794
And these beetles have been
around for thousands of years
568
00:37:45,877 --> 00:37:49,460
and have lived in harmony
and balance with the trees.
569
00:37:49,543 --> 00:37:51,877
But unfortunately,
because of climate change
570
00:37:51,960 --> 00:37:53,877
and because of
the long drought,
571
00:37:53,960 --> 00:37:56,001
millions of trees are very weak
572
00:37:56,085 --> 00:38:00,251
and have difficulty defending
themselves against the beetles.
573
00:38:00,335 --> 00:38:05,126
Biochar can definitely be
one of the ways that we address
the beetle damage
574
00:38:05,210 --> 00:38:07,752
in the dead and dying trees
of the Sierras.
575
00:38:07,835 --> 00:38:12,835
Biochar is essentially the form
of charcoal that is suitable
576
00:38:12,919 --> 00:38:14,460
for use in agriculture
577
00:38:14,543 --> 00:38:18,001
and in helping to build
more healthy soil.
578
00:38:21,043 --> 00:38:24,126
When you pyrolize woody biomass
particularly,
579
00:38:24,210 --> 00:38:28,293
about half of the carbon
that is in that woody biomass
580
00:38:28,377 --> 00:38:32,085
can be saved,
is a residual charcoal.
581
00:38:32,168 --> 00:38:35,835
And biochar is very much
like coral for the soil
582
00:38:35,919 --> 00:38:38,877
in that it can hold nutrients,
it can hold water.
583
00:38:38,960 --> 00:38:41,043
It's more of an architecture.
584
00:38:41,126 --> 00:38:42,960
It incubates life.
585
00:38:43,043 --> 00:38:46,293
You're saving about half of
the carbon that's in that plant
586
00:38:46,377 --> 00:38:49,752
and then can put it to better
use and sequestering it in soil
587
00:38:49,835 --> 00:38:52,710
for great benefit
to agriculture.
588
00:38:52,794 --> 00:38:56,085
We have all this biomass that
we have to do something with.
589
00:38:56,168 --> 00:38:58,794
They are a fire hazard and,
as you know,
590
00:38:58,877 --> 00:39:02,585
right now we have something
like ten fires in California.
591
00:39:02,669 --> 00:39:07,502
And by producing biochar
we can return some of that
material back into the forest
592
00:39:07,585 --> 00:39:11,168
in a safe manner,
or we can take some
of that biochar
593
00:39:11,251 --> 00:39:13,293
and take it down into
the Central Valley,
594
00:39:13,377 --> 00:39:16,293
which desperately needs
water savings.
595
00:39:16,377 --> 00:39:19,001
And one of the prime benefits
of biochar
596
00:39:19,085 --> 00:39:22,835
is that it can help
to retain water in soils.
597
00:39:22,919 --> 00:39:27,877
If we put biochar in
just 10% of the world's soil,
598
00:39:27,960 --> 00:39:32,835
we'll actually sequester
29 billion tons of CO2.
599
00:39:32,919 --> 00:39:35,794
29 billion tons.
That's on 10%.
600
00:39:35,877 --> 00:39:38,835
And that's using only--
quote-unquote--
601
00:39:38,919 --> 00:39:42,835
"surplus waste material,"
so that's significant.
602
00:39:44,794 --> 00:39:48,335
Gill:
And then we have
the carbon offset credits.
603
00:39:48,418 --> 00:39:50,210
And to keep those carbon
credits coming,
604
00:39:50,293 --> 00:39:53,377
we have to employ workers
to do our forest inventories,
605
00:39:53,460 --> 00:39:55,710
to work with
the carbon verifiers
606
00:39:55,794 --> 00:39:58,502
to make sure the carbon
that we say is on the property
607
00:39:58,585 --> 00:40:00,043
is on the property,
608
00:40:00,126 --> 00:40:02,460
and then is maintained
into the future.
609
00:40:02,543 --> 00:40:05,585
I'd like to think
that we're a model
that others can join in
610
00:40:05,669 --> 00:40:08,377
and do the same thing
that we're doing out here.
611
00:40:08,460 --> 00:40:10,043
This isn't rocket science.
612
00:40:10,126 --> 00:40:14,627
The carbon storage, as we move
into the future, is huge.
613
00:40:14,710 --> 00:40:17,919
And we need more larger,
614
00:40:18,001 --> 00:40:20,251
older forests, intact forests,
615
00:40:20,335 --> 00:40:22,543
that we know
will never be developed
616
00:40:22,627 --> 00:40:25,210
and can continue
into perpetuity.
617
00:40:41,835 --> 00:40:43,835
Kate Scow:
I'm Kate Scow,
and I'm a professor
618
00:40:43,919 --> 00:40:45,669
in Land,
Air and Water Resources
619
00:40:45,752 --> 00:40:47,752
at University of California,
Davis.
620
00:40:47,835 --> 00:40:50,794
And I'm a soil microbial
ecologist.
621
00:40:50,877 --> 00:40:54,251
So the carbon cycle
on a global scale
622
00:40:54,335 --> 00:40:58,085
involves aquatic systems
and terrestrial systems.
623
00:40:58,168 --> 00:41:02,293
So soil is a very
important part of the
terrestrial systems.
624
00:41:04,585 --> 00:41:07,710
Soil actually contains
two to three times
625
00:41:07,794 --> 00:41:10,001
the amount of carbon
that is in the atmosphere.
626
00:41:10,085 --> 00:41:14,835
Soil is the place where primary
productivity is supported.
627
00:41:14,919 --> 00:41:18,001
That means all the vegetation
that grows,
628
00:41:18,085 --> 00:41:22,001
that fixes CO2
through photosynthesis
629
00:41:22,085 --> 00:41:23,460
from the atmosphere,
630
00:41:23,543 --> 00:41:24,877
what miraculous, like,
631
00:41:24,960 --> 00:41:26,669
creating mass here
on the ground
632
00:41:26,752 --> 00:41:28,293
out of what? Air?
633
00:41:28,377 --> 00:41:30,669
It's, like, still amazing to me.
634
00:41:30,752 --> 00:41:33,794
That productivity brings
all this carbon in.
635
00:41:33,877 --> 00:41:36,752
The plant fixes the CO2,
it dies,
636
00:41:36,835 --> 00:41:39,043
it falls onto the ground,
637
00:41:39,126 --> 00:41:40,460
and all that plant residue
638
00:41:40,543 --> 00:41:43,126
now enters into
the soil carbon cycle.
639
00:41:43,210 --> 00:41:45,502
It's way bigger than
the atmosphere,
640
00:41:45,585 --> 00:41:48,418
what is residing in soil.
641
00:41:49,835 --> 00:41:53,794
So organic farms
obtain their nutrients
642
00:41:53,877 --> 00:41:56,293
not from synthetic fertilizers.
643
00:41:56,377 --> 00:42:00,919
The fertilizer is in the form
of organic material.
644
00:42:01,001 --> 00:42:03,919
That could be cover crops,
or it could be compost
645
00:42:04,001 --> 00:42:08,210
that's made of food wastes
or yard wastes or animal waste
646
00:42:08,293 --> 00:42:09,960
that you put in the soil.
647
00:42:10,043 --> 00:42:12,293
So in organic systems,
you may be putting
648
00:42:12,377 --> 00:42:16,335
up to eight times as much
carbon into the soil
649
00:42:16,418 --> 00:42:19,168
compared to
a conventional system.
650
00:42:19,251 --> 00:42:22,752
So it's like part of it
is really basic.
651
00:42:25,752 --> 00:42:29,877
Benyus:
Climate change
gives us an opportunity
652
00:42:29,960 --> 00:42:34,335
to really behave differently
on this planet.
653
00:42:34,418 --> 00:42:37,377
We see what we can do
at our worst,
654
00:42:37,460 --> 00:42:39,627
and now the question is,
655
00:42:39,710 --> 00:42:45,543
if we were to consciously...
656
00:42:45,627 --> 00:42:49,335
be a part of the healing...
657
00:42:49,418 --> 00:42:53,251
it'll unleash,
I think, our creativity.
658
00:42:55,335 --> 00:42:58,460
You realize, "Oh my gosh,
I have a back yard.
659
00:42:58,543 --> 00:43:02,502
Oh my gosh,
I have a park near me."
660
00:43:04,418 --> 00:43:07,669
If we were to see ourselves
as helpers
661
00:43:07,752 --> 00:43:10,460
who could help the helpers
heal this planet...
662
00:43:13,085 --> 00:43:15,418
that is so much better
than seeing ourselves
663
00:43:15,502 --> 00:43:17,919
as disruptive toddlers
with matches.
664
00:43:18,001 --> 00:43:23,335
You begin to realize that all
of us are somehow connected
665
00:43:23,418 --> 00:43:25,919
to little bits of the solution.
666
00:43:26,001 --> 00:43:29,710
Ietef Vida:
Right now we live and direct
at my mentor's house,
667
00:43:29,794 --> 00:43:33,085
the OG, the organic gardener,
Ron Finley.
668
00:43:33,168 --> 00:43:35,168
I'm more inspired to always
come here
669
00:43:35,251 --> 00:43:37,001
and learn and figure out
different ways
670
00:43:37,085 --> 00:43:39,752
to how I can actually utilize
a small plot of land
671
00:43:39,835 --> 00:43:42,418
to grow the most that I can.
672
00:43:42,502 --> 00:43:45,585
Culinary climate action is
basically what I like to see,
673
00:43:45,669 --> 00:43:50,293
when I'm growing the food
and it's basically taking all
that carbon out the atmosphere,
674
00:43:50,377 --> 00:43:51,794
it's pulling it in.
675
00:43:51,877 --> 00:43:53,335
And we also can see the fact
676
00:43:53,418 --> 00:43:55,877
that we can put it back
into the soil.
677
00:43:58,210 --> 00:44:01,210
Now only at the same time
it's creating green jobs,
678
00:44:01,293 --> 00:44:04,835
you know, and also addressing
things like diabetes and obesity
679
00:44:04,919 --> 00:44:06,502
in my community,
where I come from.
680
00:44:06,585 --> 00:44:08,460
You know, there's
a lot of plots,
681
00:44:08,543 --> 00:44:10,210
there's a lot of city access,
682
00:44:10,293 --> 00:44:12,126
there's a lot of water
that's available.
683
00:44:12,210 --> 00:44:14,919
This is really just
a beautiful cause and effect.
684
00:44:15,001 --> 00:44:19,919
We're literally pulling out
all the harmful poisons
685
00:44:20,001 --> 00:44:22,794
that we, like, literally just
emit into our atmosphere.
686
00:44:22,877 --> 00:44:26,835
And the best way
that you want to transform that
is by growing some food.
687
00:44:26,919 --> 00:44:29,251
Put it on the roof.
Put it in your window sill.
688
00:44:30,710 --> 00:44:32,835
But we feel the heat rising.
689
00:44:32,919 --> 00:44:35,251
You know, being a farmer
is being futuristic.
690
00:44:35,335 --> 00:44:36,877
There is no doomsday mentality.
691
00:44:36,960 --> 00:44:38,669
You have to actually
plant water
692
00:44:38,752 --> 00:44:40,919
and think that you're going
to reap what you sow.
693
00:44:41,001 --> 00:44:43,210
So that's the conversation
that I'd like to see
694
00:44:43,293 --> 00:44:45,835
when we're talking about
transforming the climate.
695
00:44:45,919 --> 00:44:47,335
It's not gonna happen overnight.
696
00:44:47,418 --> 00:44:50,877
But you do have to start now.
Now is the time.
697
00:45:12,502 --> 00:45:14,251
Bren Smith:
My name is Bren Smith.
698
00:45:14,335 --> 00:45:16,585
I'm the owner
of Thimble Island Ocean Farm.
699
00:45:16,669 --> 00:45:21,251
And we're here in the Thimble
Islands in Long Island Sound.
700
00:45:21,335 --> 00:45:24,377
And I was, I'm born and raised
in Newfoundland, Canada,
701
00:45:24,460 --> 00:45:27,210
high school dropout, and have
fished all over the globe.
702
00:45:27,293 --> 00:45:29,710
I fished in Gloucester
up in Newfoundland,
703
00:45:29,794 --> 00:45:32,210
and then I was in the Bering Sea
for a bunch of years.
704
00:45:32,293 --> 00:45:35,627
And, you know,
that was the height of
industrialized fishing.
705
00:45:35,710 --> 00:45:38,543
We were tearing up entire
eco-systems with our trawls,
706
00:45:38,627 --> 00:45:41,543
chasing fewer and fewer fish
further and further out to sea.
707
00:45:41,627 --> 00:45:43,502
So it was completely
unsustainable.
708
00:45:43,585 --> 00:45:45,251
In fact, a lot of the fish
I was catching
709
00:45:45,335 --> 00:45:48,585
was going to McDonald's
for their Fishwich sandwich.
710
00:45:50,794 --> 00:45:52,710
It really caused a wake-up call
711
00:45:52,794 --> 00:45:54,877
for a lot of folks
in my generation.
712
00:45:55,001 --> 00:45:56,960
I was actually out
in the Bering Sea,
713
00:45:57,043 --> 00:45:58,669
and the cod stocks crashed.
714
00:45:58,752 --> 00:46:01,418
And, you know, thousands
of people thrown out of work,
715
00:46:01,502 --> 00:46:03,752
canneries shuttered,
and it really taught me
716
00:46:03,835 --> 00:46:07,502
that you can build up an
economy and a culture over
hundreds of years
717
00:46:07,585 --> 00:46:09,502
and if you don't protect
the resources,
718
00:46:09,585 --> 00:46:12,710
eco-system collapse can wipe it
out in a matter of years.
719
00:46:15,210 --> 00:46:17,710
And that's when
we really begin to realize
720
00:46:17,794 --> 00:46:21,585
that issues like overfishing,
like climate change,
721
00:46:21,669 --> 00:46:23,335
that they're not
environmental issues
722
00:46:23,418 --> 00:46:25,251
for a lot of us
that work on the ocean,
723
00:46:25,335 --> 00:46:26,919
they're economic issues. I mean,
724
00:46:27,001 --> 00:46:29,502
there's gonna be no food,
no jobs, on a dead planet.
725
00:46:31,919 --> 00:46:33,794
When I realized
this wasn't sustainable,
726
00:46:33,877 --> 00:46:36,794
I went on this search
for sustainability.
727
00:46:36,877 --> 00:46:39,502
I remade myself
as an oysterman.
728
00:46:39,585 --> 00:46:42,460
And what oysters taught me
was that Mother Nature
729
00:46:42,543 --> 00:46:45,168
created these technologies
millions of years ago
730
00:46:45,251 --> 00:46:46,877
designed to mitigate our harm.
731
00:46:46,960 --> 00:46:48,960
We don't need advanced
technologies.
732
00:46:49,043 --> 00:46:51,794
Mother Nature has seaweeds
and shellfish
733
00:46:51,877 --> 00:46:55,085
which sequester five times more
carbon than land-based plants,
734
00:46:55,168 --> 00:46:58,460
filter 50 gallons of water
a day per oyster
735
00:46:58,543 --> 00:47:00,126
pulling nitrogen
out of our system.
736
00:47:00,210 --> 00:47:02,627
I mean, my job as
a steward of the ocean
737
00:47:02,710 --> 00:47:06,126
is to take Mother Nature's
technologies and grow them.
738
00:47:06,210 --> 00:47:08,210
And it's pretty simple.
739
00:47:08,293 --> 00:47:12,960
So the beautiful thing
about if you grow just
restorative species,
740
00:47:13,043 --> 00:47:14,835
is there's zero inputs.
741
00:47:14,919 --> 00:47:17,335
We don't need fresh water,
we don't need animal feed,
742
00:47:17,418 --> 00:47:19,835
we don't need fertilizer
and we don't need land,
743
00:47:19,919 --> 00:47:23,168
making it hands down
the most sustainable form
of food production
744
00:47:23,251 --> 00:47:25,377
on the planet.
745
00:47:25,460 --> 00:47:28,794
So kelp is
this beautiful seaweed.
746
00:47:28,877 --> 00:47:31,794
It's like the gateway drug
to a new cuisine.
747
00:47:31,877 --> 00:47:34,043
It's one of the fastest-growing
plants on earth.
748
00:47:34,126 --> 00:47:37,377
It soaks up five times more
carbon than land-based plants.
749
00:47:37,460 --> 00:47:39,210
It's called the Sequoia
of the Sea.
750
00:47:39,293 --> 00:47:41,001
But it's just the beginning.
751
00:47:41,085 --> 00:47:42,669
I mean, we're starting
with kelp,
752
00:47:42,752 --> 00:47:46,502
but there are 10,000 edible
plants in the ocean.
753
00:47:46,585 --> 00:47:49,585
Part of the plant we can turn
into kelp noodles,
754
00:47:49,669 --> 00:47:54,168
but then this is just biofuel
we turn into fertilizer
755
00:47:54,251 --> 00:47:56,293
and we can turn
into animal feed.
756
00:47:56,377 --> 00:47:59,377
If you provide a seaweed diet
to cows,
757
00:47:59,460 --> 00:48:02,627
you get a 90% reduction
in methane output.
758
00:48:02,710 --> 00:48:04,710
It's stunning.
And cows have been eating--
759
00:48:04,794 --> 00:48:08,001
cows, sheep, goats,
have been eating kelp
for hundreds of years.
760
00:48:08,085 --> 00:48:10,377
Hebrides Islands, Maine,
all sorts of places.
761
00:48:10,460 --> 00:48:11,877
You know, the volume's
stunning.
762
00:48:11,960 --> 00:48:15,377
We can do 10 to 20 tons
of kelp per acre,
763
00:48:15,460 --> 00:48:17,335
150,000 shellfish.
764
00:48:17,418 --> 00:48:18,794
And you scale this up,
765
00:48:18,877 --> 00:48:20,543
if you were to take
a network of our farms
766
00:48:20,627 --> 00:48:22,377
totaling the size
of Washington State,
767
00:48:22,460 --> 00:48:24,418
technically you could
feed the world.
768
00:48:24,502 --> 00:48:27,418
If you took five percent
of U.S. territorial waters
769
00:48:27,502 --> 00:48:29,335
and farmed in our style,
770
00:48:29,418 --> 00:48:31,210
you could create
50 million direct jobs
771
00:48:31,293 --> 00:48:35,627
and sequester the equivalent
carbon of 20 million cars.
772
00:48:37,877 --> 00:48:41,001
Our farms also help mitigate
acidification.
773
00:48:41,085 --> 00:48:44,126
The kelp creates something
called a Halo Effect
774
00:48:44,210 --> 00:48:47,752
which reduces the acidity
in the oceans,
775
00:48:47,835 --> 00:48:50,377
which then allow our oysters
and other shellfish
776
00:48:50,460 --> 00:48:52,418
to grow thicker shells
777
00:48:52,502 --> 00:48:57,085
and not be as susceptible
to acidification.
778
00:48:57,168 --> 00:48:59,877
So, I mean, climate change
was supposed to be
779
00:48:59,960 --> 00:49:03,418
this 100-year
sort of slow lobster boil.
780
00:49:03,502 --> 00:49:05,043
And instead it's here and now.
781
00:49:05,126 --> 00:49:06,752
Luckily, as fishermen,
782
00:49:06,835 --> 00:49:09,126
we can transition to something
that keeps that (indistinct)
783
00:49:09,210 --> 00:49:11,335
and have the pride of helping
feed my country,
784
00:49:11,418 --> 00:49:12,585
and that's just so exciting.
785
00:49:12,669 --> 00:49:14,460
I can be part of, you know,
786
00:49:14,543 --> 00:49:15,919
the army that's going to help,
787
00:49:16,001 --> 00:49:17,960
hopefully, save the planet.
788
00:49:30,293 --> 00:49:33,460
If we put 10 units of CO2
in the atmosphere,
789
00:49:33,543 --> 00:49:35,960
ten very large units of CO2
in the atmosphere,
790
00:49:36,043 --> 00:49:38,168
about five stay in
the atmosphere
791
00:49:38,251 --> 00:49:40,168
and about two and a half
go into plants
792
00:49:40,251 --> 00:49:42,960
and about two and a half
goes into the ocean.
793
00:49:43,043 --> 00:49:46,543
So you've got an acidic ocean.
So how do you deal with that?
794
00:49:46,627 --> 00:49:50,210
Nature handles this problem
by making more shells,
795
00:49:50,293 --> 00:49:54,001
which is the marine snow idea,
796
00:49:54,085 --> 00:49:56,168
that little beasties
grow in the water,
797
00:49:56,251 --> 00:49:59,543
they make calcium carbonate
shells, so shells fall.
798
00:49:59,627 --> 00:50:02,835
The problem with that is,
the planet loves to operate
799
00:50:02,919 --> 00:50:05,502
on time scales
of millions of years.
800
00:50:05,585 --> 00:50:08,001
And we don't.
801
00:50:08,085 --> 00:50:12,418
So, question becomes, can you
speed that process up?
802
00:50:17,126 --> 00:50:20,627
DiCaprio:
We have to investigate
all our options.
803
00:50:20,710 --> 00:50:22,960
There are more experimental
hypotheses
804
00:50:23,043 --> 00:50:25,210
that still need to be tested.
805
00:50:25,293 --> 00:50:31,543
One solution may lie
in a microscopic community
of life called marine snow.
806
00:50:33,960 --> 00:50:37,043
Stasa Puskaric:
So, fundamentally,
what do we need?
807
00:50:37,126 --> 00:50:40,669
Well, we need this planet
as it was,
808
00:50:40,752 --> 00:50:45,001
we have to bring it
in the state that
it was 200 years ago.
809
00:50:45,085 --> 00:50:48,335
Higher concentrations
of carbon dioxide,
810
00:50:48,418 --> 00:50:51,085
they increase acidity
of the ocean.
811
00:50:51,168 --> 00:50:53,877
The oceans are losing
their ability
812
00:50:53,960 --> 00:50:56,710
to capture carbon
from the atmosphere.
813
00:50:56,794 --> 00:50:59,543
And we have
to do something about it.
814
00:50:59,627 --> 00:51:02,669
We have to help these systems
815
00:51:02,752 --> 00:51:06,919
which cycle carbon
between the atmosphere,
816
00:51:07,001 --> 00:51:09,835
between the plants on the land,
817
00:51:09,919 --> 00:51:12,585
and between the oceans.
818
00:51:12,669 --> 00:51:14,960
And with marine snow,
819
00:51:15,043 --> 00:51:19,043
it just needs a little help
from us.
820
00:51:19,126 --> 00:51:23,043
The main products will be
removal of carbon dioxide
821
00:51:23,126 --> 00:51:26,085
and the production of oxygen.
822
00:51:26,168 --> 00:51:27,794
What we can do is
823
00:51:27,877 --> 00:51:31,001
insert into the ocean
very small,
824
00:51:31,085 --> 00:51:34,960
minute amounts of iron,
825
00:51:35,043 --> 00:51:36,752
but very, very little,
826
00:51:36,835 --> 00:51:38,585
so it doesn't have
anything to do
827
00:51:38,669 --> 00:51:41,251
with that term "fertilization."
828
00:51:41,335 --> 00:51:44,251
To give you a measure,
we need altogether
829
00:51:44,335 --> 00:51:47,960
about 6 kilograms of iron
for initiating this process
830
00:51:48,043 --> 00:51:52,210
on 100,000 square kilometers
of the southern oceans.
831
00:51:52,293 --> 00:51:55,835
The cells form organic matrix,
832
00:51:55,919 --> 00:51:57,794
which is the foundation
833
00:51:57,877 --> 00:52:01,168
for the formation
of the marine snow.
834
00:52:01,251 --> 00:52:05,001
It is then,
when the matrix appears,
835
00:52:05,085 --> 00:52:08,335
it becomes very attractive
for cyanobacteria
836
00:52:08,418 --> 00:52:10,627
and heterotrophic bacteria,
837
00:52:10,710 --> 00:52:14,835
which colonize these particles,
and then actively grow.
838
00:52:14,919 --> 00:52:18,251
And then we just
let them do their job,
839
00:52:18,335 --> 00:52:21,669
because they can stay suspended
840
00:52:21,752 --> 00:52:24,502
for a very long period of time.
841
00:52:24,585 --> 00:52:27,460
We tracked these
marine snow particles
842
00:52:27,543 --> 00:52:29,960
for more than four months...
843
00:52:30,043 --> 00:52:34,585
so they can float around
and sequester organic matter,
844
00:52:34,669 --> 00:52:36,293
and when they become heavy,
845
00:52:36,377 --> 00:52:39,835
they simply sink down
to the sea floor.
846
00:52:42,460 --> 00:52:45,251
The speed of this change,
847
00:52:45,335 --> 00:52:48,460
and increase
in the concentrations
and temperature--
848
00:52:48,543 --> 00:52:50,418
we must act.
849
00:52:50,502 --> 00:52:51,752
And we can.
850
00:52:51,835 --> 00:52:55,919
I'm 100% positive
that we can achieve
851
00:52:56,001 --> 00:53:00,794
um...reorganization
of human activities
852
00:53:00,877 --> 00:53:04,752
to work together with nature,
and not against it.
853
00:53:14,043 --> 00:53:18,001
DiCaprio:
Science has long proven
we have existing technologies
854
00:53:18,085 --> 00:53:21,794
that work, and they are
already being implemented.
855
00:53:21,877 --> 00:53:25,710
It's just become a matter
of political will and scale.
856
00:53:25,794 --> 00:53:30,585
We need a multitude of
solutions moving forward
simultaneously.
857
00:53:30,669 --> 00:53:33,335
In order to solve this crisis,
858
00:53:33,418 --> 00:53:38,627
it is critical we move
to 100% renewable energy now.
859
00:53:38,710 --> 00:53:40,710
Hawken:
So, the top five solutions,
860
00:53:40,794 --> 00:53:44,960
number two was onshore wind,
and that wasn't a surprise.
861
00:53:52,627 --> 00:53:56,585
Onshore wind, though,
being much greater than solar,
862
00:53:56,669 --> 00:53:59,085
was a surprise to us.
863
00:54:03,293 --> 00:54:06,835
Solar was number eight in ten,
actually.
864
00:54:11,293 --> 00:54:14,543
Martin Hermann: The sun is
the largest resource we have.
865
00:54:14,627 --> 00:54:17,251
All the other resources pale
compared to the sun.
866
00:54:17,335 --> 00:54:19,085
We have known that
for a long time,
867
00:54:19,168 --> 00:54:22,418
we just never understood how to
harvest it in an economic way.
868
00:54:22,502 --> 00:54:24,627
That's what's different now.
869
00:54:24,710 --> 00:54:28,001
Solar PV is in a stage
where we're already lower
than fossil fuel.
870
00:54:28,085 --> 00:54:30,293
Well, solar has come a long way.
871
00:54:30,377 --> 00:54:33,585
Carter in the '80s
already installed solar
in the White House.
872
00:54:33,669 --> 00:54:35,752
Reagan tore it down later on.
873
00:54:35,835 --> 00:54:38,460
And only in 2001,
874
00:54:38,543 --> 00:54:42,085
when Germany started to deploy
solar on a large scale,
875
00:54:42,168 --> 00:54:45,752
we have been getting the benefit
of economy of scale.
876
00:54:45,835 --> 00:54:48,794
Eventually we will be able
to power
877
00:54:48,877 --> 00:54:52,585
the entire electrical grids
with solar and wind,
878
00:54:52,669 --> 00:54:56,460
and all we need
is wind and storage,
and solar and storage.
879
00:54:58,960 --> 00:55:02,919
So, if you want to power
the entire United States
with photovoltaic,
880
00:55:03,001 --> 00:55:06,377
we would need about
30,000 square miles in area.
881
00:55:06,460 --> 00:55:08,460
That would give us
enough to power
882
00:55:08,543 --> 00:55:12,043
all the power grids in every
state of the United States.
883
00:55:15,210 --> 00:55:20,126
Mount Signal is a project
that powers about 70,000 homes
in San Diego.
884
00:55:20,210 --> 00:55:24,752
The second phase, the power
is going to be wheeled
to Southern California.
885
00:55:26,877 --> 00:55:30,543
The price of electricity that
we produce at Mount Signal
886
00:55:30,627 --> 00:55:33,126
is already lower
than fossil fuels.
887
00:55:33,210 --> 00:55:37,377
It's also a price that delivers
fuel price certainty
to the utility.
888
00:55:39,251 --> 00:55:42,502
The price is flat
over the next 25 years,
889
00:55:42,585 --> 00:55:48,377
not something that you get from
any other fossil fuel energies.
890
00:55:48,460 --> 00:55:51,960
We have integrated so much
solar in California already.
891
00:55:52,043 --> 00:55:55,001
Ten years ago,
people would've said, "No,
that's not really possible."
892
00:55:55,085 --> 00:55:58,251
Well, here we are,
solar is covering already
893
00:55:58,335 --> 00:56:00,627
up to 25% of California.
894
00:56:00,710 --> 00:56:03,877
The rate payer had no
material increase in pricing,
895
00:56:03,960 --> 00:56:06,335
and we're still alive,
it all works.
896
00:56:06,418 --> 00:56:10,085
And we have been able to reduce
carbon on the way there.
897
00:56:15,043 --> 00:56:17,502
Over the last years we saw now
898
00:56:17,585 --> 00:56:20,418
utilities volunteering
to buy solar.
899
00:56:20,502 --> 00:56:23,377
We see this mindset shifting.
900
00:56:23,460 --> 00:56:26,877
We still under-appreciate
the value that PV brings.
901
00:56:26,960 --> 00:56:30,585
People do not comprehend
that in five years,
902
00:56:30,669 --> 00:56:32,794
we will have PV
at much lower price.
903
00:56:32,877 --> 00:56:35,335
We will be able
to dispatch it at night,
904
00:56:35,418 --> 00:56:37,960
and you combine that with wind,
you get this paradigm
905
00:56:38,043 --> 00:56:41,543
where we are truly living
in a hundred percent
renewable environment.
906
00:56:41,627 --> 00:56:43,710
And this is feasible.
907
00:56:43,794 --> 00:56:46,752
We don't need
any new invention for that,
908
00:56:46,835 --> 00:56:48,418
we know all the technology.
909
00:56:48,502 --> 00:56:52,710
We just need to make sure that
the people responsible
910
00:56:52,794 --> 00:56:57,001
for the planning of resources,
for the infrastructure planning,
911
00:56:57,085 --> 00:57:00,669
understand that this
is a different technology,
912
00:57:00,752 --> 00:57:03,710
and it will get cheaper
over time.
913
00:57:08,001 --> 00:57:09,627
Donald Trump:
Coal is coming back.
914
00:57:09,710 --> 00:57:11,210
- Clean coal is coming back.
915
00:57:11,293 --> 00:57:13,293
A hundred percent.
916
00:57:13,377 --> 00:57:18,001
My administration is putting
an end to the war on coal.
917
00:57:18,085 --> 00:57:21,794
Gonna have clean coal,
really clean coal.
918
00:57:50,877 --> 00:57:52,794
Mann:
It's difficult enough,
sometimes,
919
00:57:52,877 --> 00:57:54,585
to communicate science
to the public.
920
00:57:54,669 --> 00:57:57,460
Now, you take that challenge,
921
00:57:57,543 --> 00:57:59,877
and you add to it
922
00:57:59,960 --> 00:58:04,919
a concerted effort
by fossil fuel interests
923
00:58:05,001 --> 00:58:06,794
and the front groups
that they fund
924
00:58:06,877 --> 00:58:09,669
to pollute the discourse
over climate change,
925
00:58:09,752 --> 00:58:13,126
to confuse the public,
to confuse policymakers.
926
00:58:13,210 --> 00:58:15,585
We need to transform
our energy sector,
927
00:58:15,669 --> 00:58:17,543
move away from
fossil fuel energy,
928
00:58:17,627 --> 00:58:19,043
towards renewable energy.
929
00:58:19,126 --> 00:58:21,126
Well, that's
rather inconvenient
930
00:58:21,210 --> 00:58:23,251
for the powerful
fossil fuel interests
931
00:58:23,335 --> 00:58:26,502
who have many millions
of dollars invested
932
00:58:26,585 --> 00:58:29,251
in our continued addiction
to fossil fuels.
933
00:58:29,335 --> 00:58:31,001
And they've fought
tooth and nail
934
00:58:31,085 --> 00:58:32,710
to maintain that addiction,
935
00:58:32,794 --> 00:58:34,627
in part by attacking the science
936
00:58:34,710 --> 00:58:38,752
linking climate change
to that behavior,
937
00:58:38,835 --> 00:58:41,251
the burning of fossil fuels.
938
00:58:45,251 --> 00:58:47,126
A question that
we get asked a lot is,
939
00:58:47,210 --> 00:58:50,418
how do we know that
the CO2 rise in the atmosphere
940
00:58:50,502 --> 00:58:52,085
is because of human activity.
941
00:58:52,168 --> 00:58:55,043
And the answer is that
we leave fingerprints
942
00:58:55,126 --> 00:58:57,919
all over the atmosphere.
943
00:58:58,001 --> 00:59:01,710
And one of the fingerprints
that we leave in the atmosphere
944
00:59:01,794 --> 00:59:06,001
is via what we call Carbon-14,
or radioactive carbon.
945
00:59:06,085 --> 00:59:08,460
So when we burn coal, oil,
and natural gas,
946
00:59:08,543 --> 00:59:10,919
we leave an imprint
on the atmosphere
947
00:59:11,001 --> 00:59:15,502
of what we call negative
Carbon-14, or less Carbon-14.
948
00:59:15,585 --> 00:59:17,710
Because fossil fuels
are so old,
949
00:59:17,794 --> 00:59:20,293
there's no Carbon-14 left,
it's all decayed away.
950
00:59:20,377 --> 00:59:23,043
We can actually measure,
very accurately,
951
00:59:23,126 --> 00:59:25,335
how much fossil fuels we burn
952
00:59:25,418 --> 00:59:27,835
by measuring C-14
in the atmosphere.
953
00:59:27,919 --> 00:59:33,085
It is nature's verification
system that we have.
954
00:59:36,293 --> 00:59:38,335
Wadhams:
They've persuaded enough people
955
00:59:38,418 --> 00:59:40,585
and sowed enough doubt
956
00:59:40,669 --> 00:59:44,585
that it's making it more
difficult than in the past
957
00:59:44,669 --> 00:59:47,168
to actually get anything done
about climate change,
958
00:59:47,251 --> 00:59:49,126
and that's really depressing.
959
00:59:49,210 --> 00:59:51,168
Mann:
And the fact is
that the agenda
960
00:59:51,251 --> 00:59:53,502
that many of these
fossil fuel corporations,
961
00:59:53,585 --> 00:59:57,210
and those who are running them
are engaged in, is malicious
962
00:59:57,293 --> 00:59:58,794
in the danger it's creating
963
00:59:58,877 --> 01:00:00,877
and the havoc that it is
wreaking on our planet.
964
01:00:00,960 --> 01:00:02,752
Hartmann:
So we've got a bunch of people
965
01:00:02,835 --> 01:00:07,418
who are literally profiting
off the death of life on Earth.
966
01:00:07,502 --> 01:00:10,460
I think that
some climate denial,
967
01:00:10,543 --> 01:00:12,669
particularly the well-funded
climate denial,
968
01:00:12,752 --> 01:00:15,460
that is being done by people
who know better,
969
01:00:15,543 --> 01:00:17,877
rises to the level of a crime
against humanity
970
01:00:17,960 --> 01:00:20,502
that probably should be
prosecuted in the Hague.
971
01:00:28,669 --> 01:00:32,752
DiCaprio:
While climate deniers have
succeeded in delaying action,
972
01:00:32,835 --> 01:00:36,168
a much more ominous problem
has emerged.
973
01:00:36,251 --> 01:00:38,960
Very recently,
scientists have recorded
974
01:00:39,043 --> 01:00:43,085
increasing levels of
methane gas in the atmosphere.
975
01:00:43,168 --> 01:00:46,502
Methane, a powerful
greenhouse gas,
976
01:00:46,585 --> 01:00:50,835
has the potential to increase
temperatures even further.
977
01:00:50,919 --> 01:00:52,835
Increased methane is a sign
978
01:00:52,919 --> 01:00:56,001
that we are reaching a critical
tipping point.
979
01:00:56,085 --> 01:00:58,001
But where is it coming from?
980
01:00:58,085 --> 01:01:02,335
And how much will it accelerate
climate disruption?
981
01:01:02,418 --> 01:01:05,085
Scientists are racing
to find out.
982
01:01:11,085 --> 01:01:13,293
Gabrielle Petron:
So, we are in front of
983
01:01:13,377 --> 01:01:15,627
the University of Wyoming
Mobile Laboratory.
984
01:01:15,710 --> 01:01:18,251
We have different
instruments inside
985
01:01:18,335 --> 01:01:21,752
that measure what's in the air
that we are breathing right now.
986
01:01:21,835 --> 01:01:23,669
It's doing that in real time.
987
01:01:23,752 --> 01:01:25,251
And we are able, like that,
988
01:01:25,335 --> 01:01:27,710
to chase emission sources
and plumes,
989
01:01:27,794 --> 01:01:31,502
and understand where
sources of pollutions
are located,
990
01:01:31,585 --> 01:01:35,418
what activities are
going on that lead
to enhanced methane.
991
01:01:38,001 --> 01:01:40,251
Inside of our lab,
we have a couple instruments.
992
01:01:40,335 --> 01:01:44,168
We have
a proton-transfer-reaction
time-of-flight mass spec
993
01:01:44,251 --> 01:01:48,085
to measure volatile organics
like benzene, toluene.
994
01:01:48,168 --> 01:01:51,168
And then we also have
a Picarro cavity ring-down
995
01:01:51,251 --> 01:01:53,502
to measure methane
concentrations.
996
01:01:53,585 --> 01:01:57,210
We can see data from these
instruments in real time
997
01:01:57,293 --> 01:02:00,710
due to an inlet we have
up on our mast above the van,
998
01:02:00,794 --> 01:02:04,043
which pulls air in and feeds
into our instruments.
999
01:02:04,126 --> 01:02:08,251
Petron:
So, we found with
aerial and road mapping
1000
01:02:08,335 --> 01:02:11,543
that we have more sources
of methane in areas
1001
01:02:11,627 --> 01:02:14,251
where we extract the gas
than we expected.
1002
01:02:14,335 --> 01:02:17,794
And to really pinpoint where
there are leaks of methane,
1003
01:02:17,877 --> 01:02:20,043
you need to be very close
to the sources.
1004
01:02:20,126 --> 01:02:23,085
And the mobile lab
gives us the flexibility
1005
01:02:23,168 --> 01:02:27,210
to pinpoint where we see
the largest leaks.
1006
01:02:27,293 --> 01:02:30,960
The company has drilled
brand-new megapad,
1007
01:02:31,043 --> 01:02:35,377
22 wells in the middle
of renewed urban development
1008
01:02:35,460 --> 01:02:37,085
in western Greeley.
1009
01:02:37,168 --> 01:02:39,377
This is a site
that had a lot of contention,
1010
01:02:39,460 --> 01:02:42,210
given its size
and its location.
1011
01:02:45,877 --> 01:02:48,418
So the local community,
from what I've heard,
1012
01:02:48,502 --> 01:02:50,919
is not really
kept up to breadth
1013
01:02:51,001 --> 01:02:52,710
on what's going on
at the site.
1014
01:02:52,794 --> 01:02:55,168
There's a huge sound wall
around the operation,
1015
01:02:55,251 --> 01:02:58,919
and the state is not really
maybe doing its best
1016
01:02:59,001 --> 01:03:01,293
at facilitating
the communication.
1017
01:03:01,377 --> 01:03:03,919
We saw operations going on
with a lot of flaring.
1018
01:03:04,001 --> 01:03:05,835
It seems very large volume
of gas.
1019
01:03:05,919 --> 01:03:08,293
The yellow color of the flame
1020
01:03:08,377 --> 01:03:11,251
tells you it's not
complete combustion.
1021
01:03:11,335 --> 01:03:13,001
So, we are going to continue
1022
01:03:13,085 --> 01:03:15,210
doing those drives to
understand those sources,
1023
01:03:15,293 --> 01:03:19,877
but also to track
what the local population
may be exposed to.
1024
01:03:19,960 --> 01:03:22,418
So some oil-
and gas-producing regions
1025
01:03:22,502 --> 01:03:25,293
have such a large
concentration of methane
1026
01:03:25,377 --> 01:03:28,627
in the atmosphere above them
that you can see it from space,
1027
01:03:28,710 --> 01:03:32,126
and that's something that was
described a few years back
1028
01:03:32,210 --> 01:03:34,043
for the Four Corners region,
1029
01:03:34,126 --> 01:03:37,293
and that's really the key
for us to be like detectives
1030
01:03:37,377 --> 01:03:41,377
and map where we see the
largest sources of emissions.
1031
01:03:53,293 --> 01:03:56,293
Don Schreiber:
So in 2014,
1032
01:03:56,377 --> 01:03:59,835
NASA scientists in cooperation
with NOAA,
1033
01:03:59,919 --> 01:04:03,085
University of Michigan,
and other scientists,
1034
01:04:03,168 --> 01:04:06,293
identified a methane hotspot
the size of Delaware
1035
01:04:06,377 --> 01:04:08,085
in the Four Corners region.
1036
01:04:08,168 --> 01:04:09,585
That methane hotspot
1037
01:04:09,669 --> 01:04:12,001
is the largest accumulation
of methane gases
1038
01:04:12,085 --> 01:04:14,168
in the United States.
1039
01:04:14,251 --> 01:04:17,877
This ranch,
this spot that we're on,
1040
01:04:17,960 --> 01:04:20,210
is approximately ground zero.
1041
01:04:20,293 --> 01:04:22,835
If you were able
to identify a middle
1042
01:04:22,919 --> 01:04:25,377
for that Delaware-shaped cloud,
1043
01:04:25,460 --> 01:04:28,335
it might very well be right here
where we're standing.
1044
01:04:28,418 --> 01:04:30,502
And it's closely identified
1045
01:04:30,585 --> 01:04:32,877
the cause of
that methane hotspot
1046
01:04:32,960 --> 01:04:37,377
to be predominantly
the emissions from drilling,
1047
01:04:37,460 --> 01:04:38,835
such as this site,
1048
01:04:38,919 --> 01:04:42,460
as well as coal and other
fossil fuels.
1049
01:04:45,293 --> 01:04:47,877
So the methane hotspot
is identified
1050
01:04:47,960 --> 01:04:50,085
basically because
of the technology
1051
01:04:50,168 --> 01:04:51,960
that NOAA and NASA had
1052
01:04:52,043 --> 01:04:54,752
following the advent
of the FLIR cameras,
1053
01:04:54,835 --> 01:04:56,585
which are the infrared cameras
1054
01:04:56,669 --> 01:05:00,210
that let us identify the leaks
and vents and flares
1055
01:05:00,293 --> 01:05:03,752
that cause the methane hotspot
to accumulate.
1056
01:05:03,835 --> 01:05:06,960
You have to think of it
in its full sense,
1057
01:05:07,043 --> 01:05:09,960
and that is 60 years and more
1058
01:05:10,043 --> 01:05:13,669
of leaking, venting, flaring,
1059
01:05:13,752 --> 01:05:16,627
and careless practices
here in the San Juan basin,
1060
01:05:16,710 --> 01:05:20,543
over a million acres,
in total 30,000 wells,
1061
01:05:20,627 --> 01:05:23,126
that have caused
that methane hotspot
1062
01:05:23,210 --> 01:05:25,210
to finally accumulate
1063
01:05:25,293 --> 01:05:27,710
and stand as evidence
1064
01:05:27,794 --> 01:05:30,669
of what natural gas drilling
1065
01:05:30,752 --> 01:05:32,919
ultimately results in.
1066
01:05:33,001 --> 01:05:34,752
People lose sight of the fact
1067
01:05:34,835 --> 01:05:38,085
that the conventional wells
created the methane hotspot,
1068
01:05:38,168 --> 01:05:41,794
and that they are
a daily culprit.
1069
01:05:46,335 --> 01:05:49,919
So, this is a conventional
natural gas well.
1070
01:05:50,001 --> 01:05:53,126
This is very typical equipment
throughout the San Juan basin
1071
01:05:53,210 --> 01:05:55,251
and many gas fields
across America.
1072
01:05:55,335 --> 01:05:57,627
This one is leaking pretty badly
1073
01:05:57,710 --> 01:06:00,251
from some of the standard
equipment that's on it.
1074
01:06:00,335 --> 01:06:02,502
This just requires, honestly,
1075
01:06:02,585 --> 01:06:06,585
a crescent wrench,
a little bit of Teflon tape--
1076
01:06:06,669 --> 01:06:09,377
some attention
will fix this leak.
1077
01:06:09,460 --> 01:06:11,126
If I had a single wish,
1078
01:06:11,210 --> 01:06:16,627
my wish would be to pull
an investor in oil and gas here
1079
01:06:16,710 --> 01:06:20,168
and stand them
where I'm standing,
let them see that leak.
1080
01:06:20,251 --> 01:06:24,001
Let them see that times 18,000
in the San Juan basin,
1081
01:06:24,085 --> 01:06:27,377
and get them to stop obstructing
a federal rule
1082
01:06:27,460 --> 01:06:29,835
that stays in place
to protect my family,
1083
01:06:29,919 --> 01:06:32,335
to protect taxpayers
across New Mexico,
1084
01:06:32,418 --> 01:06:36,001
and provide federal
fair and equal protection
1085
01:06:36,085 --> 01:06:37,960
across the western states.
1086
01:06:38,043 --> 01:06:40,210
Let's get those guys
out of the boardroom,
1087
01:06:40,293 --> 01:06:42,001
right here on
this well location,
1088
01:06:42,085 --> 01:06:45,043
let 'em look at that leak
that can be easily fixed.
1089
01:06:45,126 --> 01:06:50,126
And when I found out
that the EPA administrator,
Scott Pruitt,
1090
01:06:50,210 --> 01:06:53,460
knew that the data had come in
1091
01:06:53,543 --> 01:06:57,585
that methane leaks
and the chemicals
that come with them
1092
01:06:57,669 --> 01:07:01,710
harm children to a greater
degree than they did to me,
1093
01:07:01,794 --> 01:07:05,543
I was just outraged
that he would try again
1094
01:07:05,627 --> 01:07:08,251
to roll back the federal
protections for us.
1095
01:07:08,335 --> 01:07:11,335
You know, if someone
came onto my ranch
1096
01:07:11,418 --> 01:07:14,960
with the stated objective
of harming my children,
1097
01:07:15,043 --> 01:07:17,585
it would be over my dead body.
1098
01:07:31,210 --> 01:07:33,669
Hartmann:
250 million years ago,
1099
01:07:33,752 --> 01:07:35,585
sudden releases of methane
1100
01:07:35,669 --> 01:07:38,085
produced kind of
a secondary effect
1101
01:07:38,168 --> 01:07:42,001
that finished off large chunks
of life on Earth.
1102
01:07:42,085 --> 01:07:44,001
And one of the debates right now
1103
01:07:44,085 --> 01:07:46,251
is whether the methane
that is buried in the Arctic,
1104
01:07:46,335 --> 01:07:48,543
whether the methane that is,
you know, in the permafrost,
1105
01:07:48,627 --> 01:07:50,210
in the seas all over the world,
1106
01:07:50,293 --> 01:07:53,877
how rapidly
that will be mobilized,
1107
01:07:53,960 --> 01:07:56,627
and how destructive
that mobilization will be.
1108
01:07:58,418 --> 01:08:00,710
DiCaprio:
The release
of this ancient methane
1109
01:08:00,794 --> 01:08:04,502
may lead to exponentially
more warming.
1110
01:08:04,585 --> 01:08:08,168
Will this methane create
an apocalyptic scenario?
1111
01:08:08,251 --> 01:08:12,794
This is a question
scientists are desperately
trying to answer.
1112
01:08:12,877 --> 01:08:14,960
Jurgen Mienert:
I'm the director of the Center
1113
01:08:15,043 --> 01:08:18,251
for Gas Hydrate, Environment,
and Climate.
1114
01:08:18,335 --> 01:08:21,627
Here we have a team
of 50 to 60 scientists
1115
01:08:21,710 --> 01:08:24,460
working on understanding
the impact of methane
1116
01:08:24,543 --> 01:08:26,502
on the global climate system.
1117
01:08:26,585 --> 01:08:31,001
This methane is stored
beneath the Arctic Ocean floor
1118
01:08:31,085 --> 01:08:33,794
in huge reservoirs,
1119
01:08:33,877 --> 01:08:36,168
at locations we sometimes know,
1120
01:08:36,251 --> 01:08:38,585
but we often do not know
very much about it.
1121
01:08:38,669 --> 01:08:42,001
So, we are applying here
geophysical methods
1122
01:08:42,085 --> 01:08:45,919
to quantify the methane hydrate
reservoirs,
1123
01:08:46,001 --> 01:08:47,919
and also to see how stable
1124
01:08:48,001 --> 01:08:51,585
those methane hydrates are
today, but also in the future.
1125
01:08:53,627 --> 01:08:57,752
Methane is one of the most
aggressive greenhouse gases.
1126
01:08:57,835 --> 01:09:01,210
Methane has, fortunately,
a shorter lifetime.
1127
01:09:01,293 --> 01:09:07,085
The Earth has a natural system
for regulating input of methane
1128
01:09:07,168 --> 01:09:10,251
from the ocean
into the atmosphere.
1129
01:09:10,335 --> 01:09:12,794
And this system
is working quite efficiently.
1130
01:09:12,877 --> 01:09:17,335
But this system is also
changing, because the ocean
current system is changing,
1131
01:09:17,418 --> 01:09:19,460
the ocean temperature
is changing,
1132
01:09:19,543 --> 01:09:22,502
the ocean chemistry
is changing.
1133
01:09:22,585 --> 01:09:26,543
So, methane was in
a kind of equilibrium
for some time,
1134
01:09:26,627 --> 01:09:31,960
and during the last
couple of years, we see quite
a distinct increase in methane.
1135
01:09:32,043 --> 01:09:35,126
Do not know where this signal
is coming from,
1136
01:09:35,210 --> 01:09:37,835
and at the present time,
that, of course,
1137
01:09:37,919 --> 01:09:40,502
is putting a pressure
on the scientific community
1138
01:09:40,585 --> 01:09:42,877
to give an answer
to the politicians:
1139
01:09:42,960 --> 01:09:45,794
what is going on with the
methane in the atmosphere?
1140
01:09:45,877 --> 01:09:47,752
Where is the methane
coming from?
1141
01:09:47,835 --> 01:09:51,627
What is presently
becoming more unstable?
1142
01:09:51,710 --> 01:09:54,168
Lund Myhre:
We have done some
very comprehensive
1143
01:09:54,251 --> 01:09:56,293
measurement campaigns
where we have measured
1144
01:09:56,377 --> 01:09:59,210
at the sea floor, in the ocean,
1145
01:09:59,293 --> 01:10:02,460
at the sea surface,
and in the air at the same time
1146
01:10:02,543 --> 01:10:08,168
to understand how methane is
regulated in this whole system.
1147
01:10:08,251 --> 01:10:11,168
There is a lot of methane
stored at the sea floor,
1148
01:10:11,251 --> 01:10:14,543
and this is so much
that only a small change
1149
01:10:14,627 --> 01:10:18,960
might impact the ocean,
or the atmosphere.
1150
01:10:22,377 --> 01:10:25,335
The balance here
needs a lot more focus,
1151
01:10:25,418 --> 01:10:28,752
a lot more observations,
and combining atmosphere,
1152
01:10:28,835 --> 01:10:32,293
ocean, climate, different kind
of components together.
1153
01:10:34,752 --> 01:10:36,543
Pavel Serov:
In my profession,
1154
01:10:36,627 --> 01:10:40,669
I'm interested in studying
methane cold seeps in the ocean,
1155
01:10:40,752 --> 01:10:43,752
in the Russian Arctic,
and also in the Barents Sea.
1156
01:10:43,835 --> 01:10:45,335
It's, well, basically,
1157
01:10:45,418 --> 01:10:47,543
streams of gas bubbles
rising from the sea floor,
1158
01:10:47,627 --> 01:10:52,043
and those gas bubbles are
mostly composed of methane gas.
1159
01:10:52,126 --> 01:10:54,835
First, it's gas hydrates,
that's solid form.
1160
01:10:54,919 --> 01:10:57,710
It's basically ice-like
structures.
1161
01:10:59,710 --> 01:11:03,919
Also, the gas can be present as
free gas, which is gas bubbles.
1162
01:11:04,001 --> 01:11:07,502
Plumes of methane bubbles
can vary.
1163
01:11:07,585 --> 01:11:09,168
In some areas in the Arctic,
1164
01:11:09,251 --> 01:11:13,293
we find gas seeps as tall as
800, 900 meters.
1165
01:11:15,335 --> 01:11:16,794
And the water depth
in these areas,
1166
01:11:16,877 --> 01:11:19,418
a little more
than 1,200 meters.
1167
01:11:19,502 --> 01:11:22,293
In shallower areas, we often
find gas seeps
1168
01:11:22,377 --> 01:11:24,710
that are almost reaching
the sea surface.
1169
01:11:24,794 --> 01:11:29,210
East Siberian Sea is definitely
an area of concern for guys
studying methane,
1170
01:11:29,293 --> 01:11:31,585
in particular
because it's so shallow there.
1171
01:11:31,669 --> 01:11:36,960
So, those methane bubbles have
really high potential to get
to the sea surface.
1172
01:11:37,043 --> 01:11:39,126
Some areas, Spitzbergen,
1173
01:11:39,210 --> 01:11:43,251
we find the methane flares
that are almost reaching
the sea surface.
1174
01:11:50,418 --> 01:11:53,794
DiCaprio:
We have warmed the atmosphere
to such a degree
1175
01:11:53,877 --> 01:11:57,126
that we have hit the tipping
point of a melting Arctic.
1176
01:11:57,210 --> 01:12:00,085
We now face the potential
1177
01:12:00,168 --> 01:12:02,960
for an abrupt
climate change scenario.
1178
01:12:03,043 --> 01:12:07,335
Current models predict
we will shoot way past
the Paris Agreement,
1179
01:12:07,418 --> 01:12:10,377
to five degrees and more,
1180
01:12:10,460 --> 01:12:16,043
causing even more catastrophic
tipping points to be activated.
1181
01:12:16,126 --> 01:12:17,960
Rothman:
Warming might lead
1182
01:12:18,043 --> 01:12:21,460
to large
injections of methane
into the atmosphere.
1183
01:12:21,543 --> 01:12:24,168
It's something
we need to be concerned about.
1184
01:12:24,251 --> 01:12:29,168
I would only add that it's one
of many possible stressors.
1185
01:12:29,251 --> 01:12:31,835
We move into
a high-risk situation
1186
01:12:31,919 --> 01:12:35,085
where we don't really
have any experience
1187
01:12:35,168 --> 01:12:38,877
and we don't know how
to deal with it.
1188
01:12:59,752 --> 01:13:02,669
Guobrandsson:
The permafrost,
and methane in general,
1189
01:13:02,752 --> 01:13:04,710
is of a great concern.
1190
01:13:04,794 --> 01:13:08,710
And I think that
this is something
1191
01:13:08,794 --> 01:13:13,126
perhaps we need to pay more
attention to methane in general,
1192
01:13:13,210 --> 01:13:16,001
in relation to
the climate issue.
1193
01:13:16,085 --> 01:13:18,794
My concerns are that
1194
01:13:18,877 --> 01:13:23,085
there are great reservoirs
of methane in the world,
1195
01:13:23,168 --> 01:13:24,877
in particular in the Arctic.
1196
01:13:24,960 --> 01:13:27,919
It is the risk of going
beyond the tipping point
1197
01:13:28,001 --> 01:13:30,293
where it will be
difficult to go back
1198
01:13:30,377 --> 01:13:33,168
and reverse the problem.
1199
01:13:42,251 --> 01:13:47,543
Tans:
It's a very plausible feedback
mechanism that in Arctic soils,
1200
01:13:47,627 --> 01:13:49,293
permafrost soils,
1201
01:13:49,377 --> 01:13:52,335
there's an enormous amount
of organic material frozen.
1202
01:13:52,418 --> 01:13:55,794
And the amount that is
available there, potentially,
1203
01:13:55,877 --> 01:14:00,251
to turn into CO2 and methane is
maybe three times, four times
1204
01:14:00,335 --> 01:14:04,001
all of the fossil fuels
that we have burned.
1205
01:14:10,919 --> 01:14:15,919
If we take all this material
out of the deep freeze...
1206
01:14:16,001 --> 01:14:20,293
you very likely get large CO2
and methane emissions
1207
01:14:20,377 --> 01:14:22,794
on a huge scale,
1208
01:14:22,877 --> 01:14:25,585
over which we have no control.
1209
01:14:29,251 --> 01:14:32,794
Katey Walter Anthony:
I study methane emissions
from lakes.
1210
01:14:32,877 --> 01:14:35,043
We are in interior Alaska,
1211
01:14:35,126 --> 01:14:38,502
and we are in
discontinuous permafrost.
1212
01:14:40,043 --> 01:14:41,418
The thing that we're looking at
1213
01:14:41,502 --> 01:14:43,126
is microbial methane.
1214
01:14:43,210 --> 01:14:45,502
This methane
bubbling here behind me,
1215
01:14:45,585 --> 01:14:48,085
it's dead plant
and animal remains
1216
01:14:48,168 --> 01:14:49,835
that were locked up
in permafrost
1217
01:14:49,919 --> 01:14:51,794
for tens of thousands of years.
1218
01:14:51,877 --> 01:14:53,794
And as that permafrost
is thawing,
1219
01:14:53,877 --> 01:14:57,293
the microbes eat
that soil carbon,
1220
01:14:57,377 --> 01:14:59,335
and they turn it into methane.
1221
01:15:00,877 --> 01:15:03,460
This process
of permafrost thawing,
1222
01:15:03,543 --> 01:15:07,502
and that thawing permafrost
fueling methane production,
1223
01:15:07,585 --> 01:15:10,460
and then methane
escapes into the atmosphere,
1224
01:15:10,543 --> 01:15:12,627
causes climate warming,
1225
01:15:12,710 --> 01:15:14,710
which causes
more permafrost to thaw,
1226
01:15:14,794 --> 01:15:16,877
we call that
a permafrost carbon feedback.
1227
01:15:16,960 --> 01:15:18,502
It is a natural process.
1228
01:15:18,585 --> 01:15:20,335
Our concern, though,
1229
01:15:20,418 --> 01:15:22,752
is that as climate warms
1230
01:15:22,835 --> 01:15:26,627
at a faster rate than it has
in the last 10,000 years,
1231
01:15:26,710 --> 01:15:29,043
that permafrost
is going to respond
1232
01:15:29,126 --> 01:15:30,835
by thawing a lot more quickly
1233
01:15:30,919 --> 01:15:33,585
and releasing,
at a faster rate, methane gas.
1234
01:15:33,669 --> 01:15:36,335
Now every time
I go to a new lake,
1235
01:15:36,418 --> 01:15:38,585
I attempt to light
these gas pockets.
1236
01:15:38,669 --> 01:15:40,502
Because it's a very high
concentration of methane,
1237
01:15:40,585 --> 01:15:42,168
it's highly flammable,
1238
01:15:42,251 --> 01:15:44,835
we see a positive flame test
when they contain methane.
1239
01:15:44,919 --> 01:15:47,335
So it's a quick gas
chromatograph on the lake
1240
01:15:47,418 --> 01:15:49,043
to tell us do we have
a methane lake,
1241
01:15:49,126 --> 01:15:52,210
or are we dealing with
a different kind of lake?
1242
01:15:52,293 --> 01:15:55,168
There are many new lakes
forming that were not here
1243
01:15:55,251 --> 01:15:57,877
30 or 60 years ago...
1244
01:15:57,960 --> 01:16:03,335
and those lakes have 10 to 100
to 1,000 times more methane
than the rest of the lakes.
1245
01:16:05,585 --> 01:16:08,418
They are a picture of the type
of methane emissions
1246
01:16:08,502 --> 01:16:13,001
we expect to see
in the next 10 to 50 years
1247
01:16:13,085 --> 01:16:16,418
as permafrost warms and thaws,
1248
01:16:16,502 --> 01:16:18,877
and that permafrost feedback
cycle kicks in
1249
01:16:18,960 --> 01:16:20,502
and really accelerates.
1250
01:16:23,460 --> 01:16:26,543
Rothman:
Now, is it methane,
is it permafrost,
1251
01:16:26,627 --> 01:16:31,627
is it the dissolved
organic carbon in the ocean
which is suddenly remobilized?
1252
01:16:31,710 --> 01:16:35,418
These things are all
intertwined with each other.
1253
01:16:35,502 --> 01:16:39,043
So, really what one
needs to ask is:
1254
01:16:39,126 --> 01:16:41,877
are there positive feedbacks
within the system?
1255
01:16:41,960 --> 01:16:43,585
The answer is yes.
1256
01:16:43,669 --> 01:16:47,251
So, it just stands to reason,
purely by common sense,
1257
01:16:47,335 --> 01:16:51,502
the less you disturb it,
the better off things will be.
1258
01:17:03,502 --> 01:17:09,085
DiCaprio:
We have the solutions at hand,
but the question still remains.
1259
01:17:09,168 --> 01:17:14,960
Can we mobilize
and take collective action
before it's too late?
1260
01:17:15,043 --> 01:17:18,126
Wadhams:
There isn't the oomph
in the world to do this.
1261
01:17:18,210 --> 01:17:21,585
They talk about,
with the Paris Agreement,
1262
01:17:21,669 --> 01:17:24,877
how we must reduce
our carbon emissions
1263
01:17:24,960 --> 01:17:28,460
and to keep temperature rise
at some low level,
1264
01:17:28,543 --> 01:17:31,877
but in fact, of course,
we won't be able to do that.
1265
01:17:33,794 --> 01:17:35,877
The technology that can save us
is something
1266
01:17:35,960 --> 01:17:39,210
that would take carbon dioxide
out of the atmosphere.
1267
01:17:41,418 --> 01:17:43,293
So it ought to be obvious
1268
01:17:43,377 --> 01:17:46,710
that the biggest research
effort that man is involved in
1269
01:17:46,794 --> 01:17:50,877
should be to develop
direct air capture methods
that work.
1270
01:17:52,960 --> 01:17:55,335
If we do that,
then we can save the world,
1271
01:17:55,418 --> 01:17:57,794
and so why don't we do it?
1272
01:18:08,960 --> 01:18:11,460
Christof Gebald:
Direct air capture is machines
1273
01:18:11,543 --> 01:18:15,168
which take in ambient air and
extract the CO2 from this air.
1274
01:18:15,251 --> 01:18:18,669
For the last ten years,
we have been working on
direct air capture,
1275
01:18:18,752 --> 01:18:22,794
with the goal of making it
with the least possible
energy impact,
1276
01:18:22,877 --> 01:18:24,960
and ultimately
with the best economics.
1277
01:18:25,043 --> 01:18:28,835
This machine consists of four
40-foot shipping containers,
1278
01:18:28,919 --> 01:18:31,543
and can be any size,
there is no limit to it.
1279
01:18:31,627 --> 01:18:33,543
So we take in the ambient air
here.
1280
01:18:33,627 --> 01:18:37,126
And inside,
we have our filter structure.
1281
01:18:39,335 --> 01:18:41,960
We get the waste heat
of the waste incinerated
1282
01:18:42,043 --> 01:18:43,293
to drive this plant.
1283
01:18:44,335 --> 01:18:46,043
Once the CO2 is captured,
1284
01:18:46,126 --> 01:18:48,710
this gas is then going
to a greenhouse,
1285
01:18:48,794 --> 01:18:51,043
and this greenhouse
is using the CO2
1286
01:18:51,126 --> 01:18:53,085
to increase
the CO2 concentration
1287
01:18:53,168 --> 01:18:55,418
in the atmosphere
of the greenhouse.
1288
01:18:55,502 --> 01:18:58,543
Which is done already nowadays,
but with fossil CO2,
1289
01:18:58,627 --> 01:19:01,960
and from tomorrow on, they're
going to use atmospheric CO2.
1290
01:19:05,919 --> 01:19:08,710
This plant will allow
to close a carbon cycle.
1291
01:19:08,794 --> 01:19:11,710
So, of course, the CO2
goes into the greenhouse,
1292
01:19:11,794 --> 01:19:14,460
and goes to the tomatoes
and cucumbers,
1293
01:19:14,543 --> 01:19:17,502
and once we eat them, the CO2
goes back to the atmosphere.
1294
01:19:17,585 --> 01:19:20,418
But since we recapture the CO2
from the atmosphere,
1295
01:19:20,502 --> 01:19:21,877
it's a closed cycle.
1296
01:19:21,960 --> 01:19:25,418
So, this can be a missing piece
of the pie
1297
01:19:25,502 --> 01:19:28,919
in order to close
a global carbon cycle
1298
01:19:29,001 --> 01:19:31,502
in the energy
or transportation sector.
1299
01:19:34,627 --> 01:19:37,794
So, besides using CO2
in a greenhouse like this,
1300
01:19:37,877 --> 01:19:40,919
we can take CO2,
we can take water,
1301
01:19:41,001 --> 01:19:42,627
and we can take
renewable energy.
1302
01:19:42,710 --> 01:19:46,835
We can again produce fuels--
for example, jet fuel.
1303
01:19:46,919 --> 01:19:51,627
In order to capture
1% of global CO2 emissions,
1304
01:19:51,710 --> 01:19:55,543
we would need roughly 300,000
of the plants behind me,
1305
01:19:55,627 --> 01:19:57,585
which is of course
a very high number.
1306
01:19:57,669 --> 01:20:00,627
But if you compare this
to existing infrastructures,
1307
01:20:00,710 --> 01:20:03,126
it's a scale
which humanity can handle.
1308
01:20:03,210 --> 01:20:07,001
So, it's definitely
an achievable goal.
1309
01:20:12,085 --> 01:20:15,835
The next project is to bring
a plant to Iceland
1310
01:20:15,919 --> 01:20:18,043
to capture CO2 from the air
1311
01:20:18,126 --> 01:20:22,418
and sequester
the CO2 underground.
1312
01:20:22,502 --> 01:20:26,460
And in two hours, you literally
turn CO2 into a stone,
1313
01:20:26,543 --> 01:20:30,085
which stores it in a permanent
and safe manner.
1314
01:20:32,835 --> 01:20:36,710
In order to run the plant,
we would use geothermal heat.
1315
01:20:38,502 --> 01:20:40,669
There's an abundance of it
on Iceland,
1316
01:20:40,752 --> 01:20:43,752
therefore we would have
low carbon footprint energy
1317
01:20:43,835 --> 01:20:46,168
available to drive the machine.
1318
01:20:46,251 --> 01:20:48,085
Jan Wurzbacher:
So, today
is a very special day.
1319
01:20:48,168 --> 01:20:52,168
We have brought CO2 capture
plant up here to Iceland.
1320
01:20:52,251 --> 01:20:54,669
And we are taking CO2
out of the air,
1321
01:20:54,752 --> 01:20:56,960
and then pumping it underground,
1322
01:20:57,043 --> 01:20:59,752
storing it in
the basalt rock formation
1323
01:20:59,835 --> 01:21:01,293
within the CarbFix project.
1324
01:21:01,377 --> 01:21:03,043
So, we extract CO2 from the air
1325
01:21:03,126 --> 01:21:06,377
and permanently remove it
by turning it into rock.
1326
01:21:06,460 --> 01:21:08,669
And yesterday night
was the first time
1327
01:21:08,752 --> 01:21:12,377
that atmospheric CO2
was injected into the ground.
1328
01:21:12,460 --> 01:21:14,835
We can go up to thousands,
ten thousands,
1329
01:21:14,919 --> 01:21:18,293
hundred thousands, and even up
to millions of tons of CO2
1330
01:21:18,377 --> 01:21:21,585
per year that can be extracted
from the atmosphere.
1331
01:21:21,669 --> 01:21:23,210
That is actually,
to our knowledge,
1332
01:21:23,293 --> 01:21:25,001
the first time ever
in the world
1333
01:21:25,085 --> 01:21:26,835
that direct air capture of CO2
1334
01:21:26,919 --> 01:21:29,919
has been combined
with underground safe
1335
01:21:30,001 --> 01:21:32,085
and permanent storage of CO2.
1336
01:21:35,335 --> 01:21:38,710
Benyus:
Yeah, it's a new relationship
with carbon.
1337
01:21:38,794 --> 01:21:40,210
Why can't we find a way
1338
01:21:40,293 --> 01:21:42,001
to make it an ingredient
for something?
1339
01:21:42,085 --> 01:21:43,877
Why can't we put it
in our plastics
1340
01:21:43,960 --> 01:21:45,418
or in our building materials?
1341
01:21:45,502 --> 01:21:48,043
Or through the help
of carbon dioxide chemistry,
1342
01:21:48,126 --> 01:21:51,502
turning carbon dioxide into the
things that we need every day?
1343
01:22:07,168 --> 01:22:12,418
I'm Daniel Nocera,
the Patterson-Rockwood professor
of energy at Harvard University.
1344
01:22:12,502 --> 01:22:16,418
These are my labs,
the labs where we invented
1345
01:22:16,502 --> 01:22:18,835
the artificial leaf
and the bionic leaf.
1346
01:22:18,919 --> 01:22:23,835
And what they do
is a complete photosynthesis.
1347
01:22:23,919 --> 01:22:28,835
Sunlight, air and water,
to fuels and food.
1348
01:22:30,335 --> 01:22:32,377
Think about photosynthesis.
1349
01:22:32,460 --> 01:22:35,585
If you think about
what it really does,
1350
01:22:35,669 --> 01:22:38,001
it's the building block
of life,
1351
01:22:38,085 --> 01:22:40,085
and its building blocks,
literally,
1352
01:22:40,168 --> 01:22:44,627
are CO2, water, and sunlight.
1353
01:22:44,710 --> 01:22:47,877
And we build all of this,
like this,
1354
01:22:47,960 --> 01:22:53,210
wood and food,
and starch, and biomass.
1355
01:22:53,293 --> 01:22:56,335
That's a remarkable
transformation.
1356
01:22:56,418 --> 01:23:00,502
This photosynthetic process,
it's very complex,
1357
01:23:00,585 --> 01:23:02,794
but we really listen to nature.
1358
01:23:02,877 --> 01:23:05,627
And that, we finally ended up
doing in 30 years.
1359
01:23:05,710 --> 01:23:08,335
And something that makes us
really happy,
1360
01:23:08,418 --> 01:23:11,835
not only can I say yes,
we can do it artificially,
1361
01:23:11,919 --> 01:23:15,794
I can do it ten times better
than photosynthesis.
1362
01:23:15,877 --> 01:23:19,919
We made special catalysts that
coated the artificial leaf,
1363
01:23:20,001 --> 01:23:23,752
and then they would split water
to hydrogen and oxygen.
1364
01:23:23,835 --> 01:23:27,502
The second part of the
invention is the bionic leaf.
1365
01:23:27,585 --> 01:23:30,835
It takes the hydrogen
from the bacteria
1366
01:23:30,919 --> 01:23:32,669
and then it makes fuels.
1367
01:23:32,752 --> 01:23:36,210
And so, depending on what genes
I put into the bacteria,
1368
01:23:36,293 --> 01:23:39,585
I could have the bacteria
make materials,
1369
01:23:39,669 --> 01:23:41,335
they could make drugs.
1370
01:23:41,418 --> 01:23:44,460
We've shown
they can make fertilizer.
1371
01:23:44,543 --> 01:23:47,669
We can work
out of any water source,
1372
01:23:47,752 --> 01:23:51,460
including natural waters,
sea water.
1373
01:23:51,543 --> 01:23:53,460
As long as you have
my artificial leaf,
1374
01:23:53,543 --> 01:23:55,835
you can do it in your backyard.
1375
01:23:55,919 --> 01:24:00,919
We don't need to dig what's been
down there and release more CO2.
1376
01:24:01,001 --> 01:24:03,960
The artificial leaf,
working with the bionic leaf,
1377
01:24:04,043 --> 01:24:06,418
takes the CO2
out of the atmosphere,
1378
01:24:06,502 --> 01:24:08,877
uses sunlight and water,
and we make fuel.
1379
01:24:09,001 --> 01:24:14,293
So, we don't add any more
to the atmosphere, any more CO2.
1380
01:24:14,377 --> 01:24:18,543
And it's another issue, because
the cost I'm up against,
1381
01:24:18,627 --> 01:24:22,919
the developed world has spent
tens of trillions of dollars
1382
01:24:23,001 --> 01:24:24,418
to build what they now use.
1383
01:24:24,502 --> 01:24:26,168
It's kind of hard
to walk away from
1384
01:24:26,251 --> 01:24:28,627
a multi-trillion dollar
investment
1385
01:24:28,710 --> 01:24:29,877
that you've paid off.
1386
01:24:29,960 --> 01:24:31,752
So, that's what it's all about.
1387
01:24:31,835 --> 01:24:37,001
Therefore, you need policy
and you need good partnership.
1388
01:24:37,085 --> 01:24:42,460
And the public informing them
that they have options,
1389
01:24:42,543 --> 01:24:46,293
and that there can be
this different world.
1390
01:24:50,335 --> 01:24:53,043
DiCaprio:
This new world
can be sustainable,
1391
01:24:53,126 --> 01:24:55,335
innovative, and profitable.
1392
01:24:55,418 --> 01:24:58,877
The green economy
is creating millions of jobs,
1393
01:24:58,960 --> 01:25:01,085
and will create millions more.
1394
01:25:01,168 --> 01:25:03,210
It matches and will surpass
1395
01:25:03,293 --> 01:25:06,460
the economy of
the fossil fuel industry.
1396
01:25:06,543 --> 01:25:09,418
The challenge
to reverse climate disruption
1397
01:25:09,502 --> 01:25:12,585
opens up opportunity
for everyone.
1398
01:25:12,669 --> 01:25:17,293
It is now more profitable
than ever to be green.
1399
01:25:21,293 --> 01:25:22,919
Hawken:
Up until recently,
1400
01:25:23,001 --> 01:25:27,251
the profit you could make
from creating the problem
1401
01:25:27,335 --> 01:25:30,210
was greater
than the profit
1402
01:25:30,293 --> 01:25:31,835
you could make
from the solutions.
1403
01:25:31,960 --> 01:25:34,377
So, the solutions
had to be done with subsidies,
1404
01:25:34,460 --> 01:25:36,752
which were rare
and non-existent,
1405
01:25:36,835 --> 01:25:40,085
or altruism, or faith.
1406
01:25:40,168 --> 01:25:42,627
But people who are making
the problems were raking it in,
1407
01:25:42,710 --> 01:25:44,293
raking it in, raking it in.
1408
01:25:44,377 --> 01:25:46,418
And I think we're at a crossover
1409
01:25:46,502 --> 01:25:49,710
where actually the profit
you can make from the solutions
1410
01:25:49,794 --> 01:25:52,210
is greater than the profit
from the problems.
1411
01:25:52,293 --> 01:25:54,543
And that is not well understood.
1412
01:25:54,627 --> 01:25:57,085
So it's not that altruism
need not apply,
1413
01:25:57,168 --> 01:25:58,460
it's a great thing.
1414
01:25:58,543 --> 01:26:01,251
But actually,
altruism will not be needed
1415
01:26:01,335 --> 01:26:04,835
in order to move towards a world
where we reverse global warming,
1416
01:26:04,919 --> 01:26:07,877
because in fact,
it's less expensive.
1417
01:26:07,960 --> 01:26:12,168
It's more profitable,
more beneficial, more jobs.
1418
01:26:12,251 --> 01:26:14,794
It's the most amazing thing
that's happened
1419
01:26:14,877 --> 01:26:16,460
in the last few years,
1420
01:26:16,543 --> 01:26:19,001
and it's going to do
nothing but increase
1421
01:26:19,085 --> 01:26:20,335
as the years go by,
1422
01:26:20,418 --> 01:26:22,710
because engineers
and designers,
1423
01:26:22,794 --> 01:26:25,043
and basically
who are unknown and unnamed,
1424
01:26:25,126 --> 01:26:28,168
have been working diligently,
and are working diligently
1425
01:26:28,251 --> 01:26:32,168
to reinvent a new way
of being a human being
1426
01:26:32,251 --> 01:26:34,085
relating to this planet.
1427
01:26:53,126 --> 01:26:56,794
James Murray:
In Orkney, we have a really
strong maritime tradition.
1428
01:26:56,877 --> 01:27:01,043
And since the '70s, the oil
and gas industry in Aberdeen
1429
01:27:01,126 --> 01:27:03,377
has been a major contributor
to the local economy,
1430
01:27:03,460 --> 01:27:05,627
providing tens
and thousands of jobs.
1431
01:27:05,710 --> 01:27:07,293
But really,
in the last few years,
1432
01:27:07,377 --> 01:27:08,627
we've seen quite a big downturn
1433
01:27:08,710 --> 01:27:10,543
in terms of
the oil and gas industry
1434
01:27:10,627 --> 01:27:12,085
and the price of oil.
1435
01:27:12,168 --> 01:27:14,752
But we've got lots
of really experienced people
1436
01:27:14,835 --> 01:27:17,210
in offshore operations
on our doorstep,
1437
01:27:17,293 --> 01:27:20,126
and they're finding new jobs
in offshore renewables
1438
01:27:20,210 --> 01:27:22,001
and companies such as ourselves.
1439
01:27:25,293 --> 01:27:29,043
Tidal energy is almost
an entirely untapped resource.
1440
01:27:29,126 --> 01:27:31,043
We think we have the potential
around the world
1441
01:27:31,126 --> 01:27:34,669
for about 100 gigawatts
of capacity, perhaps more.
1442
01:27:34,752 --> 01:27:37,835
And what that equates to
is a low-carbon energy
1443
01:27:37,919 --> 01:27:40,669
for millions
and millions of homes.
1444
01:27:43,001 --> 01:27:45,460
What we've got here
is the world's most powerful
1445
01:27:45,543 --> 01:27:48,085
floating
tidal energy generator.
1446
01:27:48,168 --> 01:27:49,919
We've got a floating platform
1447
01:27:50,001 --> 01:27:52,168
to which two rotors
are mounted.
1448
01:27:57,043 --> 01:27:59,085
Worker:
We start with
the rotors turning,
1449
01:27:59,168 --> 01:28:00,669
which produces electricity,
1450
01:28:00,752 --> 01:28:02,377
which comes back up
into the machine
1451
01:28:02,460 --> 01:28:03,752
where it's conditioned,
1452
01:28:03,835 --> 01:28:08,335
and then it gets transformed,
and stepped up,
1453
01:28:08,418 --> 01:28:11,001
and fed back into the grid.
1454
01:28:11,085 --> 01:28:13,001
Murray:
It's like a wind turbine
on its side
1455
01:28:13,085 --> 01:28:15,418
with two rotors instead of one.
1456
01:28:15,502 --> 01:28:19,418
Chris Milne:
Two weeks ago,
we had great success.
1457
01:28:19,502 --> 01:28:23,418
First period of 24-hour
continuous generation
from the device.
1458
01:28:23,502 --> 01:28:27,126
It actually operated
beyond expectations.
1459
01:28:27,210 --> 01:28:30,794
The device itself generated
over 18 megawatt-hours of power
1460
01:28:30,877 --> 01:28:33,085
in that 24-hour period.
1461
01:28:33,168 --> 01:28:36,460
We're converging on
more traditional methods
1462
01:28:36,543 --> 01:28:37,960
of renewable generation,
1463
01:28:38,043 --> 01:28:40,794
and really putting
tidal out there
1464
01:28:40,877 --> 01:28:43,460
as a real competitive technology
across the world
1465
01:28:43,543 --> 01:28:45,335
and the world's
generation needs.
1466
01:28:47,377 --> 01:28:50,919
The tidal turbine is,
it's 63 meters long in total.
1467
01:28:51,001 --> 01:28:53,627
We do all the power conversion
within the device itself,
1468
01:28:53,710 --> 01:28:55,627
and it's ready,
then, for export
1469
01:28:55,710 --> 01:28:57,794
right into
the UK electricity grid.
1470
01:28:57,877 --> 01:29:01,835
So, you know, we're aiming
for tens of thousands
1471
01:29:01,919 --> 01:29:03,919
of these tidal turbines,
1472
01:29:04,001 --> 01:29:05,669
but this, you know,
fully integrated system
1473
01:29:05,752 --> 01:29:08,752
for producing low carbon energy,
so we're very excited about it.
1474
01:29:11,919 --> 01:29:14,627
Neil Kermode:
So, EMEC was set up
as a testing laboratory,
1475
01:29:14,710 --> 01:29:17,168
because we know that
there's a huge amount of energy
1476
01:29:17,251 --> 01:29:20,043
in the oceans
all around the world,
1477
01:29:20,126 --> 01:29:22,669
and we're trying to find a way
to harvest it.
1478
01:29:22,752 --> 01:29:25,835
And so, we realized that one
of the most important things
1479
01:29:25,919 --> 01:29:28,251
was to have a test center
which would allow us
1480
01:29:28,335 --> 01:29:30,335
to find out
how to do this properly.
1481
01:29:30,418 --> 01:29:32,752
So, what we've got
is a site here
1482
01:29:32,835 --> 01:29:34,835
where we've got cables
that are out in the sea
1483
01:29:34,919 --> 01:29:37,669
that allow developers
of these machines
1484
01:29:37,752 --> 01:29:39,877
to put these machines
on to our cables,
1485
01:29:39,960 --> 01:29:43,377
and the electricity
is then brought on to shore.
1486
01:29:43,460 --> 01:29:45,585
And that then feeds
into our national grid.
1487
01:29:45,669 --> 01:29:47,085
So, this is real.
1488
01:29:47,168 --> 01:29:49,794
This is making electricity
out of seawater.
1489
01:29:51,710 --> 01:29:54,126
So, at the moment, we've got
a device called the Penguin,
1490
01:29:54,210 --> 01:29:56,335
and that's by a company
called Wello Oy,
1491
01:29:56,418 --> 01:29:57,960
and their machine
is effectively
1492
01:29:58,043 --> 01:30:01,293
a large pendulum
inside a ship.
1493
01:30:01,377 --> 01:30:02,710
And as the ship moves,
1494
01:30:02,794 --> 01:30:04,543
this pendulum
turns horizontally,
1495
01:30:04,627 --> 01:30:06,710
and that then
generates electricity.
1496
01:30:06,794 --> 01:30:08,210
The sea is unrelenting,
1497
01:30:08,293 --> 01:30:10,377
and it will really try
and damage equipment.
1498
01:30:10,460 --> 01:30:13,043
So, making the equipment
as reliable, robust,
1499
01:30:13,126 --> 01:30:15,752
efficient, cost-effective,
all these things
1500
01:30:15,835 --> 01:30:17,502
are the things that people
are grappling with.
1501
01:30:17,585 --> 01:30:19,043
But the really clever thing is,
1502
01:30:19,126 --> 01:30:20,710
we have done
that piece of alchemy.
1503
01:30:20,794 --> 01:30:22,960
We've actually turned seawater
into electricity.
1504
01:30:23,043 --> 01:30:26,460
And that really is huge,
because people are worried about
1505
01:30:26,543 --> 01:30:28,126
whether you can do this or not
for years,
1506
01:30:28,210 --> 01:30:29,418
and we've just shown you can.
1507
01:30:29,502 --> 01:30:31,543
And that's a big step forward.
1508
01:30:55,585 --> 01:30:58,460
Lund Myhre:
No one can say that
the scientist has not warned,
1509
01:30:58,543 --> 01:31:03,085
has not told that we have
to reduce the emissions
of greenhouse gases.
1510
01:31:03,168 --> 01:31:04,835
That should be clear to many.
1511
01:31:04,919 --> 01:31:06,210
How much farther can we go?
1512
01:31:06,293 --> 01:31:07,752
How many more tipping points
can we go
1513
01:31:07,835 --> 01:31:09,335
before we hit a tipping point
1514
01:31:09,418 --> 01:31:12,752
from which our civilization
cannot recover,
1515
01:31:12,835 --> 01:31:15,418
or from which the life
of this planet,
1516
01:31:15,502 --> 01:31:18,335
or a large portion of the life
on this planet cannot recover?
1517
01:31:18,418 --> 01:31:21,460
We cannot allow ourselves
to reach those points.
1518
01:31:21,543 --> 01:31:23,043
And we're so damn close to it.
1519
01:31:23,126 --> 01:31:24,960
Smith:
We're at a turning point.
1520
01:31:25,043 --> 01:31:28,460
Either we can stay the course
and drown, burn,
1521
01:31:28,543 --> 01:31:30,293
and starve ourselves to death
1522
01:31:30,377 --> 01:31:32,293
in the face
of the climate crisis,
1523
01:31:32,377 --> 01:31:35,543
or we can come together,
we can innovate.
1524
01:31:37,001 --> 01:31:38,251
Hawken:
Where do we stand?
1525
01:31:38,335 --> 01:31:40,794
Is it possible?
Is it game over?
1526
01:31:40,877 --> 01:31:42,418
Or is it, in fact, game on,
1527
01:31:42,502 --> 01:31:44,627
which is that we have at hand
1528
01:31:44,710 --> 01:31:47,627
the ability, capacity,
and solutions
1529
01:31:47,710 --> 01:31:49,418
that can reverse
global warming,
1530
01:31:49,502 --> 01:31:52,293
not mitigate, not reduce,
not stabilize,
1531
01:31:52,377 --> 01:31:54,168
but reverse?
1532
01:31:54,251 --> 01:31:55,835
When you make
your goals bigger,
1533
01:31:55,919 --> 01:31:57,335
it opens up possibility.
1534
01:31:57,418 --> 01:31:59,377
It opens up imagination.
1535
01:31:59,460 --> 01:32:02,502
It opens up innovation.
It doesn't foreclose.
1536
01:32:02,585 --> 01:32:04,502
It actually does the opposite.
1537
01:32:04,585 --> 01:32:07,794
And so, it's not that
there's one solution,
1538
01:32:07,877 --> 01:32:11,710
but together,
you can achieve drawdown
1539
01:32:11,794 --> 01:32:14,585
by doing 80% of the solutions.
1540
01:32:14,669 --> 01:32:18,502
Every one of them
has so many cascading benefits,
1541
01:32:18,585 --> 01:32:20,502
makes a better world
for everybody.
1542
01:32:20,585 --> 01:32:25,085
So, we don't lose
by understanding
1543
01:32:25,168 --> 01:32:26,835
that climate change
is happening
1544
01:32:26,919 --> 01:32:30,251
and responding to it,
so what's the problem?
1545
01:32:37,460 --> 01:32:39,210
DiCaprio:
We are the first generation
1546
01:32:39,293 --> 01:32:41,960
to see the advance
of climate disruption,
1547
01:32:42,043 --> 01:32:45,460
and the last
with a chance to fix it.
1548
01:32:45,543 --> 01:32:47,585
In spite of all this evidence,
1549
01:32:47,669 --> 01:32:50,126
we are currently
burning fossil fuels
1550
01:32:50,210 --> 01:32:52,710
at an ever-increasing rate.
1551
01:32:52,794 --> 01:32:54,543
We have heard
from the scientists
1552
01:32:54,627 --> 01:32:59,210
who have told us the truth
based on actual research.
1553
01:32:59,293 --> 01:33:02,919
It is time to end the delay,
to listen,
1554
01:33:03,001 --> 01:33:06,377
and to implement
the solutions at hand.
1555
01:33:06,460 --> 01:33:11,043
Time is running out.
The ice is melting.
1556
01:33:11,126 --> 01:33:14,919
Decisive action
must be taken now.
1557
01:33:15,001 --> 01:33:17,460
There is no other option.
1558
01:33:17,543 --> 01:33:21,001
This moment
is within our reach.
1559
01:33:21,085 --> 01:33:23,126
Let us grasp it.
1560
01:33:23,210 --> 01:33:26,627
It is up to us,
each one of us,
1561
01:33:26,710 --> 01:33:31,960
to save this unique blue planet
for generations to come.
