Permafrost Could Cause 2.5 Times the Warming of Deforestation!
Joe Romm, ThinkProgress Back in February, a major study found
that thawing permafrost feedback will turn Arctic from carbon
sink to source in the 2020s, releasing 100 billion tons of
carbon by 2100. That study, by NOAA and the National Snow and
Ice Data Center, conservatively assumed all of the carbon would
be released as CO2 and none as the far more potent greenhouse
gas, methane (CH4). But that is unlikely, as this video of
University of Alaska, Fairbanks, assistant professor Katey
Walter Anthony, suggests: ... A new article in Nature, “Climate
change: High risk of permafrost thaw” (subs. req’d) concludes:
Arctic temperatures are rising fast, and permafrost is thawing….
Our collective estimate is that carbon will be released more
quickly than models suggest, and at l
