- Slide 5
- 250 yrs of Carbon Emissions It took 125 years to burn the first trillion barrels of oil well burn the next trillion in less than 30 years why should you care?

- Rising CO 2 over 50 Years http://earthguide.ucsd.edu/globalchange/keeling_curve/01.html
- Slide 7
- Carbon Emissions and CO 2 Carbon burned => CO 2 Linear from 1850 to 2000 - ppm CO 2 =2.55 e 10-4 *M tons C + 297 ppm (r 2 *100=99%) ~ 50% of carbon goes into atmospheric CO 2 33% into the oceans Trend is constant over 150 years is this how the biosphere will react over the next 150 years? A near perfect correlation that predicts ppm CO 2 from total carbon burned

- Forcing, Predicted Temperature, and Climate Lag, 2000 - 2100 0 F - Model built assuming ~60% of forcing is felt in ~25 years
- Slide 11
- Consequences of Warming Thinning of polar ice caps Thawing permafrost / release of methane Slowing of the thermohaline cycle Rising sea level, perhaps quickly Extreme weather events Extended regions of drought Extremes of temperature / duration Extremes of storms and hurricanes All these are consequences of only one degree F for
