Here's a video from the Arctic News blog, which is run by the people from AMEG (Arctic Methane Emergency Group). I'm not a big fan of geo-engineering, especially if it supports the continuation of business-as-usual, but as this video has some good speakers that dare speak of worst-case scenarios, and it is not an ad for geo-engineering (that will be part 2, I surmise), I think it's worth a watch:
I'm not sure how imminent a methane clathrate collapse is, but I'm not ruling anything out. As long as methane concentrations. global as well as Arctic, are not shooting up dramatically we're in the 'safe' zone (were it not for CO2, of course).
Don't forget, if you want to have regular updates on the situation with regards to methane, you can go to Apocalypse4You's website and the ESRL Data Visualization page for Barrow (or any other sites you want).
Let's make this a sort of open thread where everyone can discuss solutions if they so wish. I haven't changed my opinion that the neoclassical economic concept that drives our economies, societies and cultures needs to be replaced as soon as possible. Maybe the brainwashing of economy students needs to stop first for that to happen.
Edit: In light of my last remark, Gareth Wyn Jones asked me to link to his article called Overshooting Limits (download document by clicking this link). I read it this summer and it gets to the core of the matter very nicely. Explaining the Galbraithian Dilemma was an eye opener for me.
