re: #325 Obdicut

Extinction in the short term is impossible to figure out but unlikely, but the reduction in population in absolutely catastrophic numbers is almost completely certain.

Ecosystem adaptation really depends a lot on the rate of change (not only on the total amount of change in temperature in a given period). The impact of .3 per decade is exponentially worse than .2 per decade in terms of adaptability. “Tipping points” are possibilities, but are contingent on a lot of uncertainties. The unknown, unknowns are certainly out there - and they must be figured into any policy analysis. I think that there are a lot of uncertainties involved in predicting global impact on a 200 year time frame. Predicting regional impact, while extremely difficult at a very specific llevel, is what is most certain. The relationship between regional impact and global is a pretty tough call, IMO.
