new information about methane...

In a really interesting article in The Daily Climate University of Chicago chemist David Archer writes about his models of the effect of methane being released from the arctic.  I learned that methane doesn't last as long as CO2 once its liberated into the environment; indeed, Archer noted that we should not let concerns about methane make us lose track of the real issue--reducing the emission of CO2.  And, the 'good' take home is that he claims that his models (which I've not looked at directly) suggest that it's not that easy get a sudden huge release of methane as the arctic melts.  So, concerns that I've had based on a catastrophic and sudden release of methane may be unlikely...which is good news.
