Methane release - higher than expected

From the BBC website:

"Scientists have uncovered what appears to be a further dramatic increase in the leakage of methane gas that is seeping from the Arctic seabed. Methane is about 20 times more potent than CO2 in trapping solar heat. The findings come from measurements of carbon fluxes around the north of Russia, led by Igor Semiletov from the University of Alaska at Fairbanks."

Climate change: Copenhagen fudge and disappointment

The climate change summit ended in a mess with nothing much of substance coming out of it. Let us hope that a legal binding international agreement can be forged next year, although I have my doubts. The full text of the agreement (can you call it that even?) is available for view.

Whatever your views on the reasons for  rising global temperatures, and the scientific evidence for man's influence on this is now overwhelming, we do need to take steps to put the breaks on further rises. My biggest worry is the risk of the tundra's permafrost melting releasing huge quantities of methane. This would make the CO2 problem seem like a walk in the park. If this happens we could be looking at human life in deep deep crisis. We MUST, and can, take steps to avoid this if the data is made clear to people and we take collective action.
