is global climate change creating more hurricanes?

Es­ti­mated reading time is 2 minutes.

HUR­RI­CANE SEASON IS AL­MOST HERE! Do­rian has come and gone, for­tu­nately leaving Al­abama mostly un­scarred. Others will follow. I live in the rel­a­tively (for­merly?) mod­erate clime of the Pa­cific North­west. Ou cli­mate has also changed: We now have mas­sive thunder and light­ning storms—which used to be a rel­a­tively novel experience—and we are in the fifth year of drought that doesn’t get much at­ten­tion be­cause it’s mild com­pared to, say, California.

But we don’t re­ally have to worry about hur­ri­canes much.


The Re­ality Now email-newsletter de­livers the latest up­dates on the cli­mate so­lu­tions move­ment straight to your inbox. The Sep­tember 2019 edi­tion fea­tures “Hur­ri­canes And The Cli­mate Crisis: What You Need To Know” from the Cli­mate Re­ality Project. The ar­ti­cle’s sub-title is, “The bottom line: warmer tem­per­a­tures create a greater chance of more in­tense storms.”

Here are the opening para­graphs of “Hur­ri­canes And The Cli­mate Crisis: What You Need To Know”:

“Hur­ri­cane season is upon us—and this one could be a doozy. After ini­tially pre­dicting a pretty typ­ical At­lantic hur­ri­cane season, in terms of the number of ex­pected named and major storms, the Na­tional Oceanic and At­mos­pheric Ad­min­is­tra­tion (NOAA) re­cently re­vised its fore­cast, in­creasing the like­li­hood of an above-average hur­ri­cane season from 30 per­cent to 45 percent.

This means res­i­dents of the Caribbean and those living along the At­lantic Ocean and Gulf of Mexico coast­lines shouldn’t let their guard down—and fore­casters warn, there ap­pears to be an in­creased chance of more major hurricanes:

The overall number of pre­dicted storms is also greater with NOAA now ex­pecting 10-17 named storms (winds of 39 mph or greater), of which 5-9 will be­come hur­ri­canes (winds of 74 mph or greater), in­cluding 2-4 major hur­ri­canes (winds of 111 mph or greater). This up­dated out­look is for the en­tire six-month hur­ri­cane season, which ends Nov. 30.

There’s little ev­i­dence to sug­gest that cli­mate change ac­tu­ally cre­ates more hur­ri­canes. In­deed, NOAA it­self ex­plains that the re­vised fore­cast has more to do with di­min­ished El Nino ac­tivity in the Pacific.

But there is abun­dant in­for­ma­tion in­di­cating our changing cli­mate is su­per­charging more and more of the ones that do form. And from Hur­ri­canes Maria and Irma to Michael and Harvey, these storms are bringing al­most unimag­in­able dev­as­ta­tion much more fre­quently as a result.”
