Accelerating global warming

There's a lengthy article in the Times today. It has an interesting discussion about how feedback mechanisms in the Artic act to amplify warming (and cooling) trends in that region. Though there are clearly scientists who think that current artic melting is likely not anthropogenic and that it may merely represent an amplification of a natural fluctuation in artic weather, the general consensus seems to be the current warming and melting is the result of human influence and must be halted to avert disastrous global effects. None of this is news to attentive environmentalists, but it's always nice to read in-depth articles on the subject.
