http://geosci.uchicago.edu/~archer/reprints/archer.2005.fate_co2.pdf They make estimates of how much co2 will remain in the atmosphere: 10-15% after 10 kyears 7% after 100 kyears and state that this will have an impact on climate even then. Their comparison with nuclear waste suggests that they are not talking about the need to emit Co2 as an insurance policy against a permanent ice age, which at a 0 discount rate should matter more than any suffering of a few generations in the next few hundred years ;-) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
