Document Summary
Hisham zerriffi (with some slides courtesy of milind kandlikar) Emissions stabilization no more increases in emissions. Concentration stabilization meet a concentration target in the future. Very different future emissions paths with attendant carbon cycle outcomes. On annual basis about 50% of carbon that is emitted is removed. 2/3rd goes into oceans and 1/3rd on to land. Carbon is taken up in land and oceans (without feedback) rapidly early but uptake diminishes. 50% is taken up in < 20 years, and 20% stays forever (>>100 years) Carbon emissions stabilization stopping all emissions growth now will result in slightly more than doubling of pre-industrial level of c in the atmosphere. Bau scenarios put us at very high levels of carbon dioxide. Combating climate change is daunting we are already on path to doubling of pre- industrial levels by 2100. It is currently impossible to go back to pre-industrial concentrations by 2100. Feedbacks are likely to make it worse!
