We're doomed article of the day

Chris Mooney:
Yet at precisely this time, a growing movement argues that 2° Celsius—which corresponds to roughly 450 parts per million (ppm) of carbon dioxide in the atmosphere—simply isn’t “safe.” Famed NASA climate scientist James Hansen and the 350.org movement are pushing the boundaries of the conversation by calling for a return to levels of atmospheric carbon dioxide concentrations that we have already passed (we are currently at 390 parts per million), and that correspond to something more like 1.5°C. And in Copenhagen, a bloc of developing nations has also coalesced around this goal, citing the threats of submerged Pacific islands, a scorched Africa, and much else.
