Where are all the hurricanes :? It’s almost August and we haven’t even had a hurricane yet. What gives? Weren’t we suppose to be in an era of “super hurricanes” as the Gulf warmed up?
Global Warming does not produce more hurricanes. El Nino events, one of which we are now entering, decrease hurricane occurrence by shearing off the tops of the wind circulation patterns. So we may have fewer hurricanes this year if that trend continues.
But WHEN a hurricane does occur, high water temperatures contribute to making it stronger. So what part of this are you unsure of? You don't think the Gulf is getting warmer? You don't think that hurricanes are heat engines that are powered by the temperature differential between the water and the upper atmosphere?
Obviously we can get cat 5 hurricanes without global warming. Camille was a huge hurricane that happened prior to much of the warming we see today. But the percentage of hurricanes that are cat 4 and 5 has been rising along with temperatures in the Gulf. We can expect to see many more powerful storms as Global Warming continues.
