I was skeptical that the increase (in hurricane intensity) would be sufficient to observe by now ... (but) the increase has been much more than we would have guessed.
When you look at global hurricane activity, you really do see a trend. It's up everywhere.
This is the first time I have been convinced we are seeing a signal in the actual hurricane data.
This isn't rocket science. If you look at the record of hurricane activity in the Atlantic going back 100 years, you see that there are periods of high activity and periods of low activity.
The large upward surge in hurricane damage in the US, is clearly owing to the confluence of rapidly increasing coastal population with a decadal time-scale upswing in Atlantic hurricane activity,
