One of the most important and urgent arguments for geoeng is that the Arctic shrinkage will lead to runaway climate change as a result of methane releases. I don't know if this is the case or not!
There's a wiki on this issue, which I'm trying to improve http://en.wikipedia.org/wiki/Arctic_methane_release It covers the release of methane from permafrost and clathrates. I'm particularly interested to see if anyone can help me with the numbers. Is it just an interesting curiousity, a major concern, or are we faced with a rerun of the 'great dying'. I have no credentials to make any such conclusions and I'd really appreciate some citations, comments or edits to improve this article for everyone's benefit. I know John is very exercised about this problem, so consensus on the issue would be most helpful.
