If this is true, we’re in even deeper climate trouble than we thought:
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.
As the Wikipedia explains, there is a lot of methane locked up as frozen methane clathrate under the arctic ocean. Methane is a short-lived, but very potent greenhouse gas. If the clathrates are warmed up enough, they will release that methane, and possibly quite quickly. The upshot? Global warming going a lot faster and further than the IPCC models.
This is far scarier than a little trouble with the LIBOR…
