That's because it's cold here, freezing cold even in summer.

Some products can be stored here for up to two years without spoiling.

Here we store so flour, oil, canned meat, potato chips.

It's practical and much cheaper than a climate controlled warehouse.

Even in summer, the temperature in this ice seller is normally 15 degrees Celsius below zero.

But cousin can tell that northern Siberia is getting warmer and warmer.

Even underground.

Things were naturally kept cold here in the permafrost.

Now we've covered the seller up with sheets to keep out.

The warmth thinks year the ice seller was one or two degrees warmer, but that change isn't too bad.

It's OK thing, but for how much longer?

In the village of about a guy, there are many ice sellers like chasms.

The village depends on them for its supplies.

Overland access is only possible when the river is frozen for four months a year.

It forms the road in and out from about January to April, we can use the winter roots to receive supplies.

Vinik in the summer chasms three stores get weekly deliveries by airplane from the regional capital, Yakutsk.

It's expensive but necessary, with temperatures that can drop to minus 50 degrees in winter.

Life and data guy is dictated by the cold.

Permafrost still covers the area, but it's starting to thaw.

This is the Barrack Ica Crater, just a few kilometers from the village.

It's the largest permafrost crater in the world, one kilometer wide and 100 m deep, and it's growing.

The crater was originally caused by deforestation as the frozen earth was no longer protected by trees.

Today it's also exposed to the rising Arctic temperatures.

The melting permafrost sets off a vicious cycle.

The organic substances in the eyes decompose as it melts, which releases more greenhouse gasses, which in turn speeds up global warming.

The processes were observing at the Bottega Crater are things we're seeing everywhere else, just to a lesser extent.

The ice under the ground melts thin, the ground collapses.

It happens everywhere with but a guy could crater is the perfect example of why we shouldn't mess around with the permafrost.

Smells like should it, Robson Ilsa.

But the true severity of the situation has been slow to hit home, even though the signs air clear.

Neighboring Russia Young ski is otherwise one of the coldest places in the world, but this summer, temperatures hit 38 degrees.

It's never been so hot because most houses in the Yakutia region rest on stilts in the ice.

The record temperatures could widely destabilize the building foundations.

Houses here could collapse because of the melting permafrost.

They sit on supports in the ground, just like all public water, gas and sewage systems.

If they start shifting, there could be accidents.

Global warming will cause a lot of problems here, which is what we should look good but that would be unable to clean.

The earth is also moving in Qassams Ice Seller.

Everywhere there are wide cracks like this one.

Qassim plugs them up with water, which then freezes and reinforces the walls with blocks of ice.

He says ice is always shifting, and the cracks have nothing to do with global warming.

And even if they did, he says, people here would adapt.

We'll manage even without a nice seller.

It's not that bad.

Let's hope everything turns out OK for Qassim in his ice seller, the effects of climate change still seem to be a long way off, and many people here still don't know anything but cold for most months of the year.

But that is starting to change.
