Isn't the worst case global warming scenario a sea level rise of a few centimeters over the next thirty years. Flooding of major cities sounds highly unlikely.

- MichaelSalib 16y agoGiven that climate is regulated by several different feedback loops that we only partially understand, the worst case scenario can be much much worse than a few cm sea level rise. Note that one particular failure mode for feedback control systems involves negative feedback turning into positive feedback as you make seemingly subtle changes to system parameters. The results are, needless to say, often catastrophic.
