All language subtitles for Undiscovered Worlds Arctic 2of2 BBC 1080p EN SUB_Subtitles01.ENG

There are still parts of our
planet...

..yet to be explored.

Descending!

These are remote
and unforgiving places...

I'm in.

..and the journey to reach them...

There's a very real danger of
getting trapped here.

..will push me
and a team of explorers...

THEY SHOUT

..to the limit.

It's really tight.

MUFFLED SCREAM

The reward?

Amazing!

Breathtaking new discoveries.

The thought that we're the
first people ever to see them

is almost beyond belief.

This time we're in the Arctic...

Agh!

..travelling through a remote
wilderness

that's living on borrowed time.

The ground that we're standing
on right now

hasn't been exposed to the open
world for thousands of years.

We want to reach the summit
of a vast unclimbed mountain...

It's just horrible.

We are, from here on in, looking for
possible bailouts.

..in one of the most hazardous

and hostile environments
on the planet.

Watch. Watch out.

So, we're heading for that valley
over there.

We're in Greenland,
deep in the Arctic Circle.

It's the most northerly country
on the planet

and on the front line
of climate change.

10k to the campsite.

We've spent two weeks kayaking
up the largest fjord in the world,

to see how the rapidly shrinking
sea ice is affecting the wildlife.

Can we go a little bit higher?

That is stunning!

Oh!

Wow!

Now we're heading inland

to Greenland's globally important
mountains and glaciers.

Is that the highest point?
That one there to our left? Yeah.

The route up looks incredible!

There we are. Nice one.

This uninhabited part of Greenland
is called the Stauning Alps.

These 400 million-year-old mountains

have been sculpted by great
rivers of ice.

Glaciers...

..carving through the peaks
to create these valleys.

I've never made camp anywhere
before where there are musk ox

just strolling around on the edge
of camp.

They could not be less interested
in us.

This is all down to the fact
that we are so remote.

They've got no reason to
fear human beings.

What do you think about that, Aldo?

It looks like,
from here, a Shetland pony. Bigger.

It does look like a rhino also
from here.

Somewhere between a rhino
and a Shetland pony.

THEY LAUGH

It's a rhony.

STEVE LAUGHS

Aldo Kane is an ex-Royal Marine

and is in charge of safety
on this expedition.

Our goal is sitting at the top
of a vast glacier

20km away.

It's a mountain with no name.

We want to climb it and stand
on its summit

where no human has ever stood...

..to look over one of the fastest
changing landscapes on the planet.

The Arctic is warming more than
twice as fast

as the rest of the world.

And the changes taking place
here will have a profound impact

on us all.

Probably come around here
and then down this

and exit out just over there.

Getting to the top of this
mountain...

2,080.

..will be one of the most
difficult challenges

we've taken on so far.

We need to find two campsites,
basically.

I brought along two world-class
mountaineers...

How much extra stuff is good?

..Libby Peter...

..and Tamsin Gay.

So that would make sense that there
is what we can see curving round.

Tamsin has climbed over 100
mountains worldwide

and specialises in remote
and hostile ascents.

The idea of doing something
where nobody's ever set foot before

is utterly thrilling.

THEY LAUGH

I love the idea of just not
knowing

and thinking, "Well, I'll just have
to manage somehow."

Even getting to the foot
of the mountain will be hard.

It could take several days

and we'll face formidable natural
barriers

that will each need specialist
equipment to cross.

Yeah, all right. See you later,
guys. Have a good one.

The helicopter's now taking skis and
climbing equipment...

..further up the mountain,

which we're only going to need
at a later stage of the journey.

The first barrier we have to get
across is this valley

which drains meltwater from eight
glaciers down to the sea.

We're here to climb an unclimbed
peak...

..on the other side of this
valley.

And to get there, we need to get
over that.

Ohhh.

I've not been looking forward
to this bit.

This water is freezing cold,

and the last thing we need at this
stage of the expedition

is wet clothes.

Completely preposterously, we're
standing in our pants

in the middle of Greenland.

And we're crossing a 3k
wide river in our underpants...

..in order to go skiing.

Just all completely makes sense.

It's definitely a first, yeah.

Right, let's just get
it over with.

Oh. That's starting to get painful
on the feet.

That's cold.

THEY SCREAM

God, I'm short.

I am pretty short.

That's right up to where no man ever
wants cold water. Ugh!

Ow. Ow.

Ow. Ish-ha.

Ugh. Bleugh-gi-bleugh-bleugh.

Just don't fall over now, Backshall.

Wait!

Ugh!

Ah!

Oh, that was really close.

I'm going up. I'm ascending.

Back in shallow water. Holy Moley!

Ahhh!

I think that's the worst of it done.

But freezing water isn't the only
threat we face in this valley.

ALDO GASPS

Whoa!

LIBBY GASPS

Quicksand.

As glaciers move, they grind rocks
into dust...

..and mixed with water...

..this makes quicksand.

That's deep mud there.

It's pretty alarming.

Come hard right.

We're going right up past
the knee.

Crikey. That's, um...quite scary
when you go in.

Yeah. It's horrible, isn't it?

It's complete... Properly anxiety
inducing.

Yeah, you definitely think that's
the end. Yeah.

We're through the meltwater

and back on firmer ground.

Whoa!

These are fresh polar bear
tracks.

That's the size of the footprint.

You see all the way there.

There are the toes. The claws
at the front.

That is a big, big animal.

This is a bit of a surprise to me.

I honestly didn't think
they would be here right now

and a very timely reminder
that wherever you are up here,

there could always be a bear around.

Beyond the mudflats, vegetation
can take hold.

We're now walking across tundra...

..a treeless habitat that springs
to life in the short Arctic summer.

It only exists where there's
a permanent underground layer of ice

called permafrost.

And it's home to a unique group
of animals and plants.

Check that out!

So this is a musk oxen skull.

All around we have tundra

just beginning to start coming into
flower...

..and then this bit around the
head is alive.

What's happened is that all
of the minerals, the phosphates,

the nitrates have leached
out of the skull

and they've fertilised the soil.

That's a creeping cinquefoil.

These are purple saxifrage.

And these are Arctic buttercups.

In the death of this animal,

the whole tundra has just burst
into life.

The warming trends
seen all across the Arctic

are melting the permafrost that
holds the tundra together.

The future of this entire
habitat is bleak.

Our goal today is to reach our
heli-drop

containing supplies for the next
stage of our expedition.

It's been dropped near the glacier

which leads to the base
of our mountain.

That is the entrance to our glacier
there and...

..we're probably about 7km away now
from where we want to set up camp.

The beginning of the valley is
littered

with piles of loose, shattered rock.

We've come to...

..all of the stuff that's been
dumped at the end of the glacier...

..which is up above us.

These rocky banks mark the points
our glacier used to reach.

Covering this loose ground
will be treacherous.

The extreme temperatures
in the Arctic

have a significant and, for us,
potentially lethal effect

on the rocks.

So we get a lot of snowfall
and then that snow freezes,

forces its way in between cracks
in the rock, expands,

splits rock open and then melts and
then that rock becomes loose,

so it's not actually held together
by anything any more.

It means that rock falls are
common,

a hazard we'll be living
with from here on in.

Come on, then, let's crack
this last bit.

This ground is just killer.

On a big day like today...

..it's distracting your mind,
I think is the key.

Running through films in your head,
thinking about plans for the future

and just doing things to take
your mind to a different place

for a little while and ignore
the pain in your shoulders.

Despite the exhaustion,
we need to stay alert.

ROCKS CLATTER

Well, that's a good reason not to go
any closer to the walls.

A couple of big old boulders
just bounced down.

It's so unstable, all of these rocks
here are completely loose.

They're coming down all the time

and it's really quite a dangerous
spot to be...

..walking through.

Best thing to do is just keep
on moving.

I'd kind of like it to be
about five minutes.

Struggling, if I'm honest.

After 11 hours of walking,

we've reached the kit for the next
stage of our expedition.

Woohoo! Look at that
for a pile of stuff.

Good job.

Awesome.

The whole bit through the valley

was actually really unpleasant,
wasn't it? Yeah.

Honestly, I could just go to sleep
right here...

..down on these rocks.

It's been an exhausting day

and we've only gained 400 metres
in height.

We'll camp here for the night

before the next stage of our
journey.

Another big day tomorrow.

Got a lot more height
to make up.

A lot more ground to cover.

We're heading up into the high
stuff.

At this time of year, the sun
doesn't set.

But as it skirts the horizon,
we sleep...

..trying to regain some strength

for our assault on the glacier
tomorrow.

It's 6am and time
to prepare for the day ahead.

Once we get up on the glacier,
it'll be another week at least

before I have a chance to clean
off all the crust and sweat.

So I've decided to be courageous
and take the plunge.

Oh, my God!

HE SCREAMS

So this was all ice 20 minutes ago.

HE SCREAMS

That's so painful.

Oh, it's so painful!

Oh.

But I'm clean. Hurrah!

Today, we plan to get onto
the glacier

that leads to the base of our
mountain.

We'll have to carry everything
we need

for the rest of the expedition.

There's two first-aid kits.

Flint.

A splint for femur, neck brace,
another first-aid kit.

We're fully self-sufficient.

We need to have enough
for contingencies.

Everything that we're taking
up there has to do with glaciers,

crevasse rescue,
avalanche, rock fall.

We'll be crossing new terrain
of snow covered rocks...

..before moving up onto glacial ice.

To cover this ground, we have
a whole new set of equipment.

From here on in we're going to be
travelling on skis...

..and in order to be able to
ski uphill,

we're using these.
They're called skins.

And the way it works is,

it slides in one direction and grips
in the other.

So, using these, you can go uphill.

And we'll be dragging big sleds
behind us

that have all our gear in them.

I was being optimistic thinking
they'd be about 50 kilos.

Think they may be a little bit more
than that.

We're each dragging about
90 kilos,

the equivalent of my body weight.

All right, then. Let's see if I can
even move this thing.

We have a vertical kilometre...

..of ascent to do before we can even
think about making a base camp.

So...

..just put our backs into it...

..and get stuck in.

You've got to keep the momentum up.

If you go too fast, it kind
of gets all jerky.

Got to stay sort of smooth and
slow.

Definitely quite hard work.

And we're not even going up anything
particularly steep at the moment.

I think I'm basically a husky.

Cross-country skiing's supposed
to be

the most perfect exercise
in the world.

You're using more muscles
than any other kind of activity.

And you feel it. There are little
muscles that I just don't use

that are already screaming.

The beauty of this landscape

can lull you into a false
sense of security.

But the dangers are never far away.

Aldo?

There's a rock fall here.

Yeah, mate. We're coming.

We've got a big rock slide
that's come down in front of us

so we can't carry on skiing up
this side.

We're going to have to cross back
over to the other side.

Watch, you're right on a big hump.

Hang on just a sec.

Yeah, just give us a little lifty.
Thanks, dear.

Amazing, amazing.

Our heavily laden sleds can only
travel on snow or ice.

Cheers.

Nice work.

OK, I'll come back down and give you
a push.

It's all right, I think
Tamsin's got me.

Oh, that's much easier.

Thank you very much.

Are you all up? Yeah.

Clear.

This year Greenland has experienced

two of the most extreme

temperature spikes on record.

These mountains are held
together by ice...

Fresh avalanche.

..but as Arctic temperatures
continue to increase, it melts.

Look at all this avalanche
debris.

After three hours of skiing through
this unpredictable landscape,

we've reached another obstacle.

This is the end of the glacier.

This huge wall of compacted ice,

spanning from one side of the valley
to the other, is on the move.

Each year it melts and recedes about
20 metres further up the valley...

..leaving behind rocks and revealing
the earth beneath.

It's amazing to think that the
ground that we're standing on

right now hasn't been exposed to the
open world for thousands of years.

The glacier we're heading
up to you now is stunning and huge

and impressive, but its days
are numbered.

To get onto the glacier, we must
drag our sleds up a snow-covered

slope steeper than anything
we've faced so far.

Only thing is, is that underneath
that blanket of snow

are great crevasses, trenches,
that drop down 30, 40 metres

into the glacier and they are
probably the most dangerous thing

for any mountaineer.

Even small cracks can open
up into vast caverns.

Ooh, a little crevasse.

Our skis offer some protection
with crevasses...

STEVE GASPS WITH EFFORT

..spreading our weight and allowing
us to span any breaks in the ice.

Ah.

Thighs...burning.

With the harsh Arctic sun beating
down, the snow is starting to melt.

The snow is so slushy,
skins aren't even working now.

Keep going, John,
just a little bit more.

As...the day's getting warmer,

the snow's getting heavier
and slidier.

We just hit our steepest patch,

and the film crew really
struggling to get up with...

..all the equipment.

VOICEOVER: Our crew hope to come
with us to the foot of the mountain

to film our ascent,
but the going is tough.

It's just this friction underfoot
that's the problem.

Stick with it.

It's bloody hard work, isn't it?

Ah!

Man down.

Could you help me up, please?

ALDO PANTS HEAVILY

I caught an edge.

Thank you, mate.

You all right?

That was four hours to get here.

Mate, you've got a sweat on.

Did anyone tell you
we're in the Arctic Circle?

That's going to freeze on your face.

Er...

That was a good bit of graft,
wasn't it? Yeah.

But we're up.

We've finally
made it onto the glacier...

..a vast river of compacted ice

that fell as snow
thousands of years ago.

Glacial ice like this covers
10% of all land on Earth.

It reflects the sun's rays
back into space,

acting as a giant cooling system
and shaping the climate

and weather patterns
for the entire planet.

We've been skiing for nine hours.

And we can now finally see the end
of our glacier and what lies beyond.

Just now, starting to come
for the first time into view...

..of the mountain.

There it is, our mountain.

Classic triangular shape.

The summit just screams out
wanting to be climbed.

I kind of feel it's very human
to stand at the bottom of a mountain

and think, "What would be
like to be on top of that?

"What would it look like?
What would the view be like?"

It's a powerful, powerful thought.

It quite gets to you, really.

Yeah.

This is a perfect location
for base camp.

Do we need to, like, probe and...?
Yeah.

Let's have a bit of a probe about.

It's important to just go round
and have a bit of a probe

at the snow,

just to check that we're not
camping on top of any big holes,

cos even something small could
give us a real problem, you know.

If somebody just
went down something tiny

and strained their ankle
or something,

we're so far away from help that
that would be a real problem for us.

But ultimately, also, we don't
want to have any major disasters

where somebody's entire tent
disappears into a big crevasse.

Having established that
the ice here is solid,

we set about making
camp for the night.

Making our bed,
make sure it's nice and flat.

So tempting when you're tired
to just whack the tent up

and not worry too much about it,
but every second you spend

flattening out the snow pays
dividends in the long run.

Get the tents up, get the stoves on.

Everyone needs plenty to drink
and plenty of rest,

before the next adventures.

Did you find the hot chocolate?
Yes, it's in.

Ah, thank you.

We have a bin.

Bin bag. Bin for the bowl there.

We have communal seating all
the way round, on four sides.

And then,
we have the cooking area here.

This was done hastily, not exactly
the way I would set it up,

but it's kind of working.

Here's the bar.
Things are a bit out of place.

But this is where we keep
the spoons.

Generally, everything in its place.
A safe kitchen is a clean kitchen.

LAUGHTER

We'll attempt the summit
tomorrow night.

Night will be the safest time for us
to climb, when the sun dips behind

the mountains and temperatures
drop well below freezing.

The snow will be firmer...

..easier to travel on...

..and there's less
risk of avalanche.

Morning.

How you doing?

I'm battered!

My legs, particularly,

are really tired.

Um, taken a bit of a kicking
over the last couple of days.

And...

Look up there!

Do you know what? That is amazing!

I think it's one of the most
amazing things about this -

we've not seen any signs of the
outside world,

there's total silence,

you don't see any other people,

you're just so isolated.

It's not until you see something
like that that all of a sudden,

you're reminded that there
is an outside world,

beyond this little team.

Remote though this place may be,

it's far from immune to what's

happening on the rest of the planet.

This glacier that we're on now

is on borrowed time.

This will be gone within,
if not my lifetime,

then the lifetime
of my grandchildren.

The rapid changes seen
here are a sign of what's

eventually to come
for the whole of the country.

These glaciers border a massive ice
sheet that covers 80% of Greenland.

It's seven times the size of the UK
and in some places, over 3km thick.

It's called the Greenland Ice Sheet

and it's shrinking
at an alarming rate.

The Greenland ice cap is
melting and when it goes,

it'll lead to global sea level
rises of six metres,

which means that a billion people
are going to be out of a home.

Over the next 80 years,

sea levels are predicted
to rise by over half a metre.

And unless we curb our addiction
to fossil fuels, the ice sheet,

like these glaciers,
will melt away altogether.

This environment is changing
over decades.

All the more reason to savour it
while we can

because it's not going to
be like this for long.

Have you got a knife in your pocket,
anyone?

We're now facing the hardest

and most dangerous
stage of the expedition.

Sleeping here at night, you can

hear rock fall coming down all
round us in this amphitheatre.

I guess we just have to be careful

and these guys are super-experienced
at that side of things.

I make that 39 and a half.

Whoa-ho!

Today, we all need to rest,

refuel and pack as lightly
as possible for the climb tonight.

Operation Hydration!

That's all the water that
I can carry with me

for the entire climb.

Supposed to be packing
fairly lightly.

It's really easy cos you think,
"Oh, I might need that,

"I might need that."
You just have to think about it.

And then decide, "No, I'm not going
to take it," and be brutal.

Deciding if you can afford to
take two teabags or just one.

No toothbrush. No toothbrush, yeah.
No toothpaste.

Every tiny extra gram you take,
you'll feel it.

We're not taking camping equipment,
so until we get back down,

we won't be able to sleep.

Given the difficulties
we've already faced,

even Libby and Tamsin are concerned.

We really don't know what the
conditions are going to be like,

so we just don't know how fast
we're going to be able to move,

even on the simple terrain.

We're going, "Is it going to be two
hours to that point,

"or is it going to be five?"

And often, you'll have a guide book
description of a route you're doing,

so you know exactly what you need
to take, what conditions you need.

We don't have that.

Looks like there's quite
a drop down.

If anything happens, a broken finger
isn't great cos it might prevent

you climbing, so any tiny thing,
we're just miles from any help.

The whole team's safety is
everyone's responsibility.

We're all totally
reliant on each other.

It's 5pm
and temperatures are dropping.

We're leaving base camp
and most of the film crew behind.

Specialist cameraman Keith Partridge
is the only crew member who

will join us on the climb.

Once we get moving, it's going to
feel like hard work, actually.

Got the camera kit, rucksack.

This mountain towers over
the glacier below.

We'll need crampons
and ice axes to climb it.

Our first 200m of ascent

is on this sheer slope,
covered with hard snow.

So, we're on our way.

Oh, yuck!

It's just horrible snow!

Just like a top layer of crust.

Foot goes through it and then you
go down well above your knees.

You can spread your weight a little
bit, I'm not sinking quite so badly.

The snow slope has melted in
the sun, then refrozen...

..leaving a crust of fragile ice,
with loose powder beneath.

Momentum is your friend

on this kind of terrain.

Stop for a second

and you sink.

Keep moving
and you might just get away with it.

It's impossible to get any traction.

Urgh!
Talk about one step forward...

..and two steps back!

This is hard work!

Haven't even started yet!

We're certainly not racing up
it like we hoped.

In fact,
we're moving at a snail's pace.

We need to reach the top of this
snow slope before we can get

a look at the route ahead
and the summit we're aiming for.

The scale of the challenge
is daunting.

Hard work!

You've always got to check
yourself every second,

make sure you don't kick
anything down on the guys below you.

Watch out!

Bit of sliding snow.

Goddamn it!

Watch out!

Nearly there.

Amazing!

Yes!

For the first time,
I can see what we're taking on

and it's actually flippin' massive!

Oh!

We have a vertical kilometre to
climb, on a knife edge ridge,

if we're to reach the summit.

It's quarter to ten at night
on the longest day of the year.

Pretty cool!

It's the first day of the Arctic
summer

and the sun won't set for another
month.

The snow now gives way to more
technically demanding climbing.

OK, chocks away, tally ho,

toodle-pip, and all that.

Tamsin steps up to take
over the lead.

OK, Steve. Coming.

Shall I let this run out, Tamsin?
Yeah, that's a good idea, Aldo.

We're climbing in a buddy system.
Aldo, Tamsin and I in one group...

..and Libby with cameraman Keith.

We're roped together.

If one of us falls,
the others must use their strength

and weight to save them.

But if you take a big fall, you
could drag your friends with you.

OK, so watch out, Aldo. Yeah.

I'm struggling to find anything
to push or pull on.

Every single rock you're
standing on is coming away.

I'm just picking my way
very carefully.

Normally with climbing,
rock is your friend,

giving you solid hand
and foot holds,

and something to anchor
to for safety.

But it's pretty clear this isn't
going to be that sort of climb.

Nice one, Steve.

Right now,
this is less like climbing

and more like tiptoeing
along a wire.

Just watching every single footfall,

trying not to dislodge anything.

And that's not easy
because everything is ready to go.

Ridge lines are a magnet
to mountaineers,

often offering the safest
route to the summit.

OK, I'm having to start to climb.
Shout if anything comes back.

But there's nothing safe about this.

Ever so gently.

That's perfect, just there, if
you don't mind stopping there. Yeah.

This whole thing is just
a pile of rubble.

There is nothing that you can trust
with your hands or your feet.

Every single move that we
make for however long we're climbing

here is going to have to be precise.

We're not even
a quarter of the way up.

Faced with sheer loose rock,
the only thing that will keep us

safe is total concentration.

There's no prospect of sleep.

We need to strike a balance
between caution,

which will take time...

Whoop!

Running out of water already.

..and rapid progress,
which could lead to exhaustion.

The intensity of the climb,

hour after hour, is exhausting...

I'd be lying if I said

I wasn't quite tired.

Need some water.

..but it looks like worse
is yet to come.

We could now be facing the most
dangerous section of the climb.

Got quite a lot of weaving to do
between these rock towers.

Potentially be a struggle up there.

Ahead are three rock pinnacles...

..steeper than anything
we've faced so far

and overhanging
in places.

We're about four hours now
up on the main ridge.

Steve's just reached
a bit of a step,

which has taken him quite a
bit of time to get round.

Even that doesn't feel
particularly secure.

Tapping the rock is one way
to check if it's solid.

If it sounds hollow,
this could mean there's air behind

and any weight on it
might cause it to fall.

Careful of that block, mate.

Unprecedented warming is releasing
the rock from the ice that usually

binds it together like glue.

Landslides and rock fall
here in Greenland

will get worse
as temperatures increase.

Almost every bit that he put his
hands on or his boots or his

crampons on was giving way
and tumbling down the hill.

You OK?

Rock! Rock!

INDISTINCT

You OK, Steve?

Yeah.

After a while,

the sound of rock fall starts
to wear on your nerves.

In usual climbing,

you hear it once in a blue moon
and it's a bad, bad sign.

On ground like this...

..it becomes almost constant.

I've reached a place I can stop

and it's Aldo's turn to climb.

Steady as she goes, mate.

Some huge big bits of air
in-between those rocks.

Just have to be super...

..light on my feet.

It's hard.

It's tenuous.
It's really quite serious.

We're going to push
on a little bit further,

but I think in the back of our minds
we know we have to rationalise

our expectations somewhat.

What does that mean?

Er... Well...

It means that we are going
to be from here on in

looking for possible bailouts,

keeping them in the back
of our mind,

knowing that we might
have to use them.

We certainly don't want to be going
back down that lot.

I'm going to drop a rock here. Yeah.

That's not a euphemism for anything.

Oh, yuck.

It looks like we have about
400 metres to go,

but right now our dreams of standing

on the summit feel a lifetime away.

What's it like,
that section, Tamsin?

I mean, it's not a barrel
of laughs but it's doable.

When you go through
that section there, Aldo,

both loose on either side.

Like everything else.

We're being forced into
dangerous climbing positions...

..with a chance of knocking
rocks off onto each other

more acute than ever.

Steve. Yeah, mate?

Once you get up top, you'll be a bit
of an anchor for both of us.

Mate, I'm all over it.

We're taking it in turns to lead
the climb while the others belay,

acting as an anchor.

OK, mate, I'm underneath you.

Tamsin has reached the top
of the last pinnacle.

She has nowhere to secure the rope,

so we'll have to rely on her body
weight to stop me if I should fall.

OK? Yes.

I've got a couple of choices
of footholds and they're all...

..rubbish

I'm in danger of knocking
something big down.

Whoa!

Sorry, mate.

I've still got quite
a bit of slack in there.

There you go.

I've made it up to Tamsin's
precarious position.

Sometimes you think you see
a spike, you put a rope over that,

so it will kind of
counterbalance it,

but when you get there it isn't
a spike or you can lift it off

and chuck it off the hill,
so that is quite tricky.

Is that you on the rope yet, Aldo?

Now it's time for Aldo...

Let me know when you're
taking it in.

..and it's my turn to act
as a counterbalance.

OK, I'm climbing.

OK, mate, go ahead.

Are you taking in?

Hang on, let me get the rope
out of this little pile of pebbles.

This is horrible.

ROCKS FALLING
Whoa!

Oh, I hate that sound.

Everything...

..is just bloody loose.

Aldo, when you get there,
just sit astride that. Yep.

Don't come over...

Perfect, great.

Lovely.

Finally, we've reached the end
of the pinnacles,

but we still have a long way to go.

If anyone's interested, it's...

..2:30 in the morning.

TAMSIN LAUGHS

It's been ten hours since
we left base camp.

It plays with your nerves,
just always...

..tiptoeing.

Half past three...

..AM.

I think you feel it
so much more, as well,

when you're tired and hungry
and thirsty.

We've been awake for 20 hours...

Ugh!

..and it's becoming harder
and harder to concentrate.

That is stunning over there.

Beautiful.

I think we're about 50 metres
from the top, from the summit now,

and that's quite satisfying.

Even more satisfying
if we get to the top.

It's not about getting to the top,
it's about taking part, Steve.

STEVE LAUGHS

Last push.

Is that the summit?

Yep.

Nearly at the top.

SHOUTING: Yes!

It's pretty special, huh?

Pretty cool.

Wow.

Great job, buddy.

Been a journey and a half.

Yeah, you could say that again.

Well done, thank you. Thank you.

That was amazing.

What a perfect summit.

Yep.

360-degree view in every direction.

Not a single person.

It's just miles and miles
and miles of mountains.

You can't conquer a mountain.

They're far bigger
than we will ever be.

They tolerate us at best.

But to be given a moment like this,

as the sun's coming up behind us...

Yeah, won't forget this in a hurry.

You do still, traditionally,
get the chance to name a peak,

the first people that climb it.

It's quite a special time
for me at the moment.

My wife's pregnant
with our first son.

So...

..I'm going to call it after the
Inuit name for first-born son...

HE SPEAKS INUIT

Standing at the end
of a shrinking glacier,

and in the heart of one
of the fastest-changing habitats

on the planet...

..if we don't act now, it's our
children who will shoulder

the burden of what's happening here.

The rate of sea level rise
has doubled in the last two decades.

This magnificent,

remote and hard-won summit...

..has allowed us the chance
to look over a landscape

that will shape our future.

It is almost six o'clock
in the morning.

It's breakfast time.
Let's put the kettle on.

We've got to get down
this thing first.
