Yale Environment 360: Methane Sources Found Bubbling Up from Melting Ice Caps

U.S. scientists report that they have discovered new sources of methane percolating up from underground reservoirs as glaciers, ice caps, and permafrost melt in the Arctic. University of Alaska researchers, conducting aerial and ground surveys, said they have discovered 150,000 methane seeps in Alaska alone near the margins of retreating glaciers or thawing permafrost. In Greenland, the seeps tended to be concentrated around the margins of ice caps that have been retreating for the past 150 years, the scientists said. Katey M. Walter Anthony, lead author of the study, published in the journal Nature Geoscience, said that these seeps in the earth’s frozen zones, or cryosphere, are not currently a major source of methane emissions. But, she added, “As the cryosphere degrades further, it could be a really big source.” Methane is a far more potent greenhouse gas than carbon dioxide, and scientists worldwide are concerned that rapid warming of the Arctic could trigger a methane “time bomb” as thawing permafrost, vegetation, and land ice result in the release of huge quantities of methane.

Game Over for the Climate

GLOBAL warming isn’t a prediction. It is happening. That is why I was so troubled to read a recent interview with President Obama in Rolling Stone in which he said that Canada would exploit the oil in its vast tar sands reserves “regardless of what we do.”
If Canada proceeds, and we do nothing, it will be game over for the climate.
*...*
The science of the situation is clear — it’s time for the politics to follow. This is a plan that can unify conservatives and liberals, environmentalists and business. Every major national science academy in the world has reported that global warming is real, caused mostly by humans, and requires urgent action. The cost of acting goes far higher the longer we wait — we can’t wait any longer to avoid the worst and be judged immoral by coming generations.


Strong words from a man I believe.
