Release of 14C-depleted methane to the atmosphere from abundant gas seeps concentrated along boundaries of permafrost thaw and receding glaciers in Alaska and Greenland Nature Geoscience (2012) Abstract Methane, a potent greenhouse gas, accumulates in subsurface hydrocarbon reservoirs, such as coal beds and natural gas deposits. In the Arctic, permafrost and glaciers form a ‘cryosphere…
The latest projections about the extent of planetary warming and the dire consequences of our growing carbon imbalance. Series: “Science at the Theater” [Science] A special Earth Day edition of Science at the Theater —”How Hot Will It Get?” — Featuring presentations by Lab climate scientists Bill Collins, Margaret Torn, Michael Wehner, and Jeff Chambers,…
“If we can limit our emissions, then the permafrost region will release less carbon to the atmosphere, there is a curve – it’s not a all or nothing question.” Ben Abbott One of the most feared of climate change “feedbacks” is the potential release of greenhouse gases by melting arctic permafrost soils. New research indicates…

Russian scientists travel to Siberia to measure output of methane from permafrost lakes.
THE world is on the cusp of a “tipping point” into dangerous climate change, according to new data gathered by scientists measuring methane leaking from the Arctic permafrost and a report presented to the United Nations on Tuesday. “The permafrost carbon feedback is irreversible on human time scales,” says the report, Policy Implications of Warming…
A UN report has warned that carbon dioxide and methane released from melting permafrost could push the climate past a tipping point and dangerously accelerate global warming.
