A flip-flop on Arctic permafrost thaws – actually a net cooling rather than a warming

Since we discussed permafrost pingos today, I thought this story from the University of Alaska Fairbanks was a good sidekick story. It seems there’s a silver lining in melting permafrost after all. Study: Climate-cooling arctic lakes soak up greenhouse gases … Continue reading

A sign of cooling? New permafrost is forming around shrinking Arctic lakes

From McGill University Researchers from McGill and the U.S. Geological Survey, more used to measuring thawing permafrost than its expansion, have made a surprising discovery. There is new permafrost forming around Twelvemile Lake in the interior of Alaska. But they … Continue reading

Antarctic Sea Ice Increase and Global Warming

by Norm Buske Although I am a long-time, casual skeptic of global warming, I agree that evidence of severe, largely anthropogenic warming of the Northern Thermal Hemisphere (NTH) is compelling. The warming of the NTH explains progressive loss of Arctic … Continue reading

New study shows Arctic sea ice extent ~6000 years ago was much less than today

This is interesting, somehow the Earth managed to reduce a good portion of the Arctic Ice Cap during the Holocene Climate Optimum from approximately 10,000-6,000 years ago without the help of the industrial revolution, fossil fuels, or automobile emissions. This … Continue reading

New PNAS paper claims Arctic planetary albedo dropped significantly, yet recent CERES data shows no significant change

From PNAS: Direct satellite observation reveals that the Arctic planetary albedo, a measure of reflectiveness, decreased from 0.52 to 0.48 between 1979 and 2011, a change in albedo that corresponds to a climate forcing 25% as large as that due … Continue reading
