Come on, come on.

We've been here for about 18 years, working with Slade Dogs on Dhe.

This has been our back door for all that time.

No, for everybody, My dog life for us, it was afraid, his good friend.

The dogs are exactly what it's all been about there being a lot of special dogs For Alan and Fiona Stewart, running sled dogs in the wildness of the cane Gold Mountains is a passion a calling.

This Arctic sport isn't just about racing.

It's a way of life.

No, you can see.

Over the years, a stray dogs have bean a massive part of our life on they The CIA is in Argentina Playschool, douche y Patagonia And, of course, this city.

Tonight happy Mimi's.

But Todd Walker.

What a hard rock.

Alan has raced all over the world, taking his dogs to the frozen extremes.

They've bean my income.

Plus also, they're all very, very much based meets your darling.

This is hardly on him and his twin brother.

I'm one of my best wheel dogs.

I have a black team, a red team on our blue team, and the black team of the best of the best, and these guys have never left the black team.

The serious serious dawg.

Five years ago, it was possible to take his dogs all the way over.

The can go RMS in this place and at this altitude on at this time of year.

Normally, you should see deep snow and deep snow, which has been on this ground four months.

It's not happening and, according to some meteorological forecasts there, saying that in a soon as 10 years time you could see the whole winter pass with no snow anywhere on the Cairngorm Plateau.

Well, if this was a normal wind to say, five years ago, you would not get on the car park, they would not have enough car parking spaces for the numbers of people who came skiing.

You know, you can imagine that you can see all the gaps here today, and there's a little 100 meter ski slope that's created by artificial snow.

So the world has changed.

You know, we would have bean coming up here.

You'd have been coming through drifts that went over the road above the height of your car.

What are you seeing?

That's changing in terms the pattern of species?

Uh, well, lower ground, I mean, because it was a new reserve.

When I came in 1976 we spent 10 years monitoring birds in different types of Pinewood.

Come up onto here.

And when we're getting into the really specialised birds, we got time going all around us here on what?

Colorado at this time of year, the white, they changed color too much.

The snore cover that we will get on the mountain.

So white Tom again, in order to remain in the lifetime again, has to be pushed right back up.

What's up the mountain, right?

Understand?

To find that I think in Scandinavia, where this has been going on as well, they're actually finding that timing are moving up.

And I think there's some indication that wanted to know not changing all the white feathers because they're realizing to survive, not repudiated.

They're gonna have to start to live in this mixed arbiter.

It may look wooden tree and feel crisp enough, but what we're witnessing here is a disaster.

70% of people have no idea of a climate change way.

All walk around in the winters.

If it's summer of the past 20 years, Alan is taking clients on training runs, but now his business is suffering.

It's the thawing that gets me here.

The way I could change crazy were up and down, up and down on the girl never gets a chance to dry.

Oh, look today wintering here.

But the truth is the grain was so soft at the beginning.

Everything I can't run dog threw this at all.

It's just all this is it exists.

It's melting so fast now, in the last couple of hours, it seriously, it's just gonna go into the ground and make it liquid again.

But that's never I had a chance to.

Fleas of Just that's what 80 80% of the trails are like this.

This Allen's Huskies work best in very cold temperatures, but now it's simply getting to back in.

When we started, our season was about seven months a year.

Now it's three.

It's the way that's killed us.

It's definitely the weather.

There won't be anybody.

There will not be a commercial side to the sled dog scene.

We just draw the lane under that, but we knew we were going to do this about 56 years ago because we saw the claim changing for our training program.

That was absolutely the push.

Climate change.

A definite couldn't hold it back.

No, I mean you through, mate.

So 1,000,000 even Canada and Alaska and my son racing at the highest level.

You make a living.

It's late dog racing in Canada and Alaska.

He was starting to see in question Really?

In Canada.

Uh, questioning Canada.

Yeah.

And questioning in the can.

Yeah, totally.

Naturally.

Well, I've got a lot of thank you's to do.

You know, my dogs, They couldn't come tonight.

Alan organized an event with his close friends, including the Arctic Explorer bore Goslin to say farewell to the Cairngorms sled dog Santa.

I've been open.

They are to assist Early nineties on is a huge, huge difference when it comes to this year's about the thickness and also the kind of the coverage.

It's been reduced by 240% since the 1990 I see it because the ice is a Latina.

So what I ski on now is much more fragile than compared to what this kid in in the early days, when I did my trips to the North Pole In the UK, the days of running sled dogs are sliding into history.

18 years, 19 Christmas is here is really quite special.

Real life for dogs.

There's a lot of side time's coming.

I can't d'oh but it's been a lot of good times.
