Thawing Arctic Cryosphere Releases Trapped Methane
22 May 2012, 12:20 pm
Brett Smith for RedOrbit.com The edges of glaciers and Arctic
permafrost are where most of the evidence of global warming can be seen, but scientists have recently been traveling to these remote locations for a different reason. Researchers from the University of Alaska at Fairbanks just published a study in the online edition of Nature Geoscience showing that methane trapped under arctic lake ...
Fireballs in the Arctic as methane seeps uncovered
22 May 2012, 10:35 am
Cows are a red herring. The most dangerous potential source for methane release lies underneath thinning
permafrost and glaciers in the Arctic. Ecologists have just mapped the seeps where methane is bubbling up, and they found more than 150,000 of them.
Study finds permafrost thaw, glacier melt releasing methane
21 May 2012, 10:46 pm
ANCHORAGE, Alaska (Reuters) - Methane from underground reservoirs is streaming from thawing
permafrost and receding glaciers, contributing to the greenhouse gas load in the atmosphere, a study led by scientists at the University of Alaska Fairbanks has found. The study, published online on Sunday in the journal Nature Geoscience, is the first to document leakage of deep geologic methane from ...
Evidence Continues to Mount for Ticking 'Methane Time Bomb'
21 May 2012, 12:53 pm
New research that utilized both ground-based measurements and aerial surveys in specific sub-arctic regions in Alaska and Greenland has discovered approximately 150,000 'methane seeps' - a phenomenon where methane gas previously held in the frozen
permafrost beneath tundras or under arctic sea ice, is steadily released when warming causes melting. read more

Methane Seeping Up From New Sources in Alaska - ibtimes.co.uk
22 May 2012, 2:46 am
Researchers from the University of Alaska, Fairbanks have found large measures of geologic methane seeping up the edges of the thawing
permafrost and receding glaciers in Alaska and Greenland. The retreat of Arctic
permafrost and glaciers often reveal ...
Release of Arctic methane could accelerate warming - New Scientist
21 May 2012, 1:10 pm
Melting Arctic
permafrost could put even more methane – a potent greenhouse gas – into the atmosphere than previously thought, with worrying implications for the pace of global warming. Many ice sheets that sit like caps over rock crevices trap natural ...
Solar panels are a smart move: Letter - nola.com

We are already experiencing the consequences with an unprecedented number of extreme weather events worldwide: droughts, heat waves, floods, blizzards, hurricanes, tornadoes; along with melting ice caps and melting
permafrost. I applaud anyone ...
Arctic melt releasing ancient methane - BBC News

"We observed most of these cryosphere-cap seeps in lakes along the boundaries of
permafrost thaw and in moraines and fjords of retreating glaciers," they write, emphasising the point that warming in the Arctic is releasing this long-stored carbon.
