I'm not sure if this is the best topical forum to put this question or not, but it seemed the most likely of the forums on pf.com. Anyhow, sorry if this is not in the right place. I've been hearing over the last year or two that climate scientists are very worried about very large releases of methane from the arctic - I dunno if it's released from the tundra, or the ice caps, or the seabeds or something, but apparently there is concern that as the earth warms, a huge amount of methane will be 'belched up' by the geography of the arctic, which will cause further warming. So, my question is, would it be impossible to exploit this huge reserve of methane? Is there no way to extract it *before* it's released by global warming? If not, would it be possible to capture it *as* it's released (I'm not sure how - I'm picturing something along the lines of giant domes made up of some thin, cheap plastic film which just trap the gas as it escapes, and funnels it into pipes or hoses for further processing [purification, liquification, etc])? If there's really that much methane, seems like it would be worth Billions of dollars, at least, on the world energy markets? Sure, burning it would produce CO2, but isn't CO2 less of a warming agent than Methane?
