The Good News: Hurricanes Are Not Getting More Frequent

As readers of this blog know, many in Big Climate want us to believe hurricanes have gotten worse as a result of global warming. Their hypothesis and concerns are not justified by the data. 

I'm feeling a little better today and I wanted to get this important information to our readers. It is freshly updated information from tropical weather expert Dr. Ryan Maue and it computes almost fifty years of hurricane/tropical storm frequency and the Accumulated Cyclone Energy index (ACE) which is the total energy of tropical systems.

The upper line on the upper graph clearly demonstrates there is no increase in hurricanes. None. There is a slight increase in tropical storms but it likely that better satellite monitoring is allowing weak tropical storms to be found and named that would not have been the case 20-30 years ago. If you are interested, Dr. Chris Landsea of the National Hurricane Center has done considerable work on this topic.

The lower graph depicts worldwide trends in the ACE index in the upper line and northern hemisphere in the lower line. We again have the issue of some additional contribution in later years due to better oceanic monitoring. There is a bit of an upward trend in both the hemispheric and worldwide ACE data but how much of this is due to better monitoring and how much, if any, is due to a changing climate is hard to discern.

What can be confidently stated that Big Climate's proclamations that the hurricanes of 2005 (Katrina, Rita, Wilma, etc.) were the "new normal" have been absolutely falsified.
