Over the past several weeks numerous articles suggest Harvey and Irma were the result of global warming. The concept is a warmer earth will generate stronger and wetter hurricanes. A number of people have said Irma was the most intense hurricane in the history of the Atlantic while Harvey was the wettest and both were good examples of what we can expect in the future because of global warming. What does a fact check reveal about these two hurricanes?
Irma was indeed a very powerful Cat 5 hurricane when it moved across the Leeward Islands and the 185 mph winds reported by a recon plane at 10,000 ft. were among the strongest recorded in Atlantic hurricanes. How does Irma compare to other intense Atlantic hurricanes? To answer that question, we must first look at the history of the methods used to determine the strength of a hurricane because it changed early this century.
