Russia will have to prove that its shelf continues the Siberian continental platform in order to enlarge its territory in the Arctic Ocean.
The East Siberian Arctic Shelf, in addition to holding large stores of frozen methane, is an additional concern because it is so shallow.
This year, that could mean the Arctic could be the warmest ever recorded since data from NASA's Goddard Institute for Space Studies show that global temperatures in 2010 have reached record levels.
Scientists think that the Arctic is endangered by pollution.
The Arctic amplification happens regardless of the cause of the global climate change.
It covers 965 populations of 365 species, representing 35 percent of all known vertebrate species found in the Arctic.
The Arctic is the world’s attic: a lot of junk lofted high into the atmosphere farther south ends up there.

The researchers studied the East Siberian Arctic Shelf, a section of the Arctic Ocean just north of Siberia.
The most powerful of feedbacks in the Arctic is sea ice and snow cover, said Miller, the lead author on a paper about past "Arctic amplification" in the journal Quaternary Science Reviews.
Warm waters passing through the strait into the Arctic Ocean might have helped reduce sea ice extent since the turn of the twenty-first century.
This past month, there has been a flurry of news, speculation, discussion and debate concerning methane gas escaping from Arctic permafrost and its impact on the global climate system.

It's also nuclear powered which means low carbon emissions, but, of course, it's a risky polluter if anything goes wrong — just one of the many paradoxes of Arctic ecology.
The unusual cold might have been driven at least partly by the Arctic Oscillation (AO).
If the Inughuit are forced to leave their ancient homeland, it is likely that the language of these Arctic hunters will disappear.
