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

permafrost

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 the Arctic and polar …

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.

Melting Arctic Ice is Releasing Massive Amounts of Methane

Researches ignite escaping methane gas from the melting ice

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 carbon dioxide, however, methane …

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.
