Deus ex Machina: Will economic collapse save us from climate catastrophe?
by Dan Allen
“I don’t think the American public has gripped in its gut what could happen. …We’re looking at a scenario where there’s no more agriculture in California.” – Steven Chu, US Secretary of Energy, http://thinkprogress.org/romm/2009/02/04/203650/chu-were-looking-at-a-scenario-where-theres-no-more-agriculture-in-california-part-2/
“[W]ith 6% per year decrease of fossil fuel CO2 emissions [beginning in 2012]…[g]lobal temperature relative to the 1880-1920 mean would barely exceed 1°C and would remain above 1°C for only about 3 decades. …[Only] this scenario provides the prospect that young people, future generations, and other life on the planet would have a chance of residing in a world similar to the one in which civilization developed.” – James Hansen, http://www.columbia.edu/~jeh1/mailings/2011/20110505_CaseForYoungPeople.pdf
“A reduction in [oil] supply of only a few percentages could create difficulties throughout the entire system. Further reductions could lead to a complete failure of critical systems.” – Rick Munroe, http://www.energybulletin.net/stories/2011-06-13/review-bundeswehr-report-peak-oil-section-22-tipping-point-nov-2010
Summary: A new paper by NASA’s James Hansen suggests that immediate and drastic declines (ca. 6% annual) in industrial CO2 emissions are required to avoid catastrophic climatic destabilization. As no realistic political solution exists for such immediate CO2 reduction, prospects for a livable future have now become dependent on a single back-breaking option: rapid global economic collapse. And in `Deus ex machina’ style, we may get it just in time…
