Methane is also beginning to escape from the permafrost.

And what they found, by doing research into the permafrost, was this bacteria.

The Arctic region consists of a vast, ice covered ocean surrounded by treeless permafrost.

It is the northernmost airport in China and the first Chinese airport built on permafrost.

Modification of substratum structure may change the permafrost levels for very long periods of time.

HEND helped lead to the discovery that 15 per cent of the surface of Mars was permafrost.

The warmer temperatures are causing the permafrost to melt, and the permafrost to melt affects the land through the erosion, and so the erosion cuts off some land that falls into the river and we lose quite a bit each year.

It's also probably one the most vulnerable of the oldest living things, because if the permafrost melts, it won't survive.

They've survived for millennia in desert, in the permafrost, at the tops of mountains and at the bottom of the ocean.

Since permafrost melts slowly, it provides a steady source of water to the eruption while keeping the water to magma ratio low.

Any removal, damage or compaction of the substratum surface can alter the thermal balance of the ground, triggering processes of permafrost degradation.

The more methane is released, the more it adds to warming, the more the permafrost melts, and the more methane is released.

The town has a heated open air swimming pool, which is supported on stilts so that the heat does not melt the permafrost.

As Earth warms, now because of extra CO2 we put in the atmosphere, ice will melt, and CO2 and methane will be released by warming ocean and melting permafrost.

In the south of the plain, where permafrost is largely absent, rich grasslands that are an extension of the Kazakh Steppe formed the original vegetation (almost all cleared now).

As Earth warms, now because of extra CO2 we put in the atmosphere, ice will melt, and CO2 and methane will be released by warming ocean and melting permafrost.

In Siberia, vast quantities of methane, an extremely potent greenhouse gas, are locked up in what used to be called permafrost regions in which it was assumed that the ground was permanently frozen.

Observations in the area of McMurdo Sound indicate that there has been no re establishment of an icy permafrost layer in disturbed materials after 30 years, suggesting that recovery must be very slow.

Seemingly dramatic changes in weather patterns including the melting of glaciers in Greenland and the thawing of the Siberian permafrost have at last convinced most business leaders that the time for action is now.

Up in Siberia, a vast area of frozen peat bog the size of France and Germany combined that we call the permafrost is melting, and as it melts, it releases huge quantities of methane.

If just three percent of the carbon locked up in the arctic permafrost is released as the world warms, it would offset all the savings that we need to make, in carbon, over the next 40 years to avoid runaway climate change.

For example, there could be wider variations in temperature, a rapid northward shift of climatic zones, lower water levels in the Great Lakes St. Lawrence Basin, rising sea levels along Canada s coasts and increased land instability in northern Canada as a result of permafrost decay.
