To make matters worse…

From Climate Progress:

The UK’s Independent reported today some pretty shocking news in “Exclusive: The methane time bomb“:

The first evidence that millions of tons of a greenhouse gas 20 times more potent than carbon dioxide is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists.

The Independent has been passed details of preliminary findings suggesting that massive deposits of sub-sea methane are bubbling to the surface as the Arctic region becomes warmer and its ice retreats.

Assuming these findings are published in a peer-reviewed publication, as is planned, they should be taken quite seriously for four reasons. First, many fear that a huge methane release is what happened during the Permian-Triassic extinction event and the Paleocene-Eocene Thermal Maximum. Second, releasing even a small fraction of the sub-sea methane would make a stabilizing greenhouse gas emissions at non-catastrophic concentrations all but impossible.
