If there were a Society of Global Warming Alarmists, Bill McKibben might get kicked out for being too much of a worry wart . . .
You've probably seen those phone-message forms with check boxes in ascending order of urgency from "FYI—no need to return call" all the way up to "the future of civilization hangs in the balance." We might see that last category as light-hearted exaggeration, but it's no laughing matter to McKibben. In his jeremiad in today's LA Times literally entitled "Civilization's last chance," McKibben solemnly declares that "the world looks a little terminal right now" and "it isn't morning in America, it's dusk on planet Earth." OK. Just so long as it's nothing serious.
McKibben's lament is based in important part on a paper that James Hansen and several co-authors have submitted to Science magazine which concludes that "if humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm."
