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.
