Hansen's model--no more than two decades for sure. The problem is we can't wait while the water rises, or in your view, to see if the water rises. There's all kind of "tipping point" theorists out there that say, essentially, once we're passed a certain point in CO2 PPM there's no going back---at least not without trying to do something we've neve done before like engineer cloud cover etc. They may be wrong, but if they're right were does that leave us?
