No one storm says anything about climate change; but nevertheless, climate change may affect weather in the aggregate. So as we wait for news about just how destructive Dean has been, let’s consider the storm from a climate perspective, bearing in mind the scientific expectation that global warming ought to intensify the average hurricane (by how much remains hotly disputed). How does Dean fit into that ongoing scientific argument?Now, that's about as honest and careful an assessment as you can get, I think. Some might argue that, when you go looking for a pattern, you run the risk of imposing one on the data. But I think it's greater folly to ignore apparent patterns in the face of what are, after all, reasonable expectations.
Well, first of all, Dean now takes its rank among the top ten most intense Atlantic hurricanes. If you look at that list you’ll see that six of the strongest (Wilma, Rita, Katrina, Mitch, Dean, and Ivan) have been in the past ten years. That’s not the kind of statistic that’s easy to overlook. According to these data we are getting more super-strong storms in the Atlantic basin than we ever have before.
If that makes any sense.
