Carbon is forever http://apocadocs.com/s.pl?1227889647
After our fossil fuel blow-out, how long will the CO2 hangover last? And what about the global fever that comes along with it? These sound like simple questions, but the answers are complex — and not well understood or appreciated outside a small group of climate scientists... University of Chicago oceanographer David Archer, who led the study with Caldeira and others, is credited with doing more than anyone to show how long CO2 from fossil fuels will last in the atmosphere. As he puts it in his new book "The Long Thaw," "The lifetime of fossil fuel CO2 in the atmosphere is a few centuries, plus 25 percent that lasts essentially forever. The next time you fill your tank, reflect upon this."

paul says: "There is a CO2 cycle - oil/coal, airborn CO2 (by burning), trees/plants breathe CO2, die, then eventually oil again. Slow but natural."
