Quick update on how hurricanes (tropical cyclones) are affected by climate change. Hurricanes that form will be:
1) more intense
2) bring more rain
3) bring higher storm surge
The only real uncertainty is how climate change will affect the *number* of these storms. There is significant uncertainty in both the magnitude and sign of the change, but most of the evidence suggests fewer tropical cyclones.
the preponderance of evidence is that tropical cyclone numbers will decline. however, we don't have a good theory for what processes regulate the number of TCs, so it's hard to have confidence in that result. but it is robustly true that the TCs that do form will be more destructive.
