New Research More than Doubles Rate of Abrupt Thawing of Arctic Permafrost Beneath Thermokarst Lakes

The warming climate may cause the release of a massive, unanticipated burst of methane and carbon dioxide long-locked up in permafrost beneath Arctic lakes by the middle of this century, according to a new study from NASA. Permafrost has been thawing more rapidly as a result of the warming climate and mean annual temperatures have been rising more rapidly in…

Thawing Russian Arctic Permafrost Leads to Anthrax Outbreak

Seventy-two nomadic herders, including 41 children, living in the Russian Arctic Circle town of Salekhard have been hospitalized since reindeer began dying en masse due to an anthrax outbreak that scientists linked to rising temperatures, which is causing permafrost to thaw.

Microbes Could Quickly Unlock Huge Carbon Stores in Arctic Permafrost

A first-of-a-kind study indicates microbial action on thawing Arctic permafrost can result in rapid increases in atmospheric CO2. Extending across northern Eurasia and Alaska, the equivalent of more than twice as much CO2 is stored in Arctic permafrost as is present in the atmosphere, highlighting the risk and threats posed by a warming climate.

Researches ignite escaping methane gas from the melting ice

Melting Arctic Ice is Releasing Massive Amounts of Methane

The melting Arctic ice is causing huge quantities of methane gas to be released into the atmosphere. Concerns about climate change-inducing greenhouse gases are often centered on carbon dioxide (CO2), but methane is a greenhouse gas that is 20-30 times more potent than CO2. Each methane molecule is actually about 70 times more potent in terms of trapping heat than a molecule of…

The Scramble for the Arctic

The Scramble for the Arctic Intensifies

Richard Sales latest book “The Scramble for the Arctic” gives a sobering account of the fate of the region as nations rush to exploit a melting Arctic.

Carbon in Thawing Northern Permafrost Double Previous Estimates

The amount of carbon frozen, stored and now thawing in northern permafrost is double previous estimates and double that contained in the atmosphere, heightening concerns that these regions will become major sources of carbon dioxide and methane emissions.

New MIT Study Shows Risks of Climate Change Doubled from Previous Assessment If No Action Taken Now

MIT has released a new study showing that risks of non-action in mitigating climate change could make expected temperature rise twice as bad as expected by the end of the century.
