As the media continues to trumpet the false narrative that climate change is causing an increase in number of hurricanes and hurricane power, the data continues to say the exact opposite.
Indeed, the downward trend is quite consistent over different timescales. Looking at data from the last 250 years or the past 50 years show the same thing: hurricanes are getting fewer in number, and waning in intensity both here in North America and globally. Given that the world has warmed approximately 1.6ºC since 1750 (near the low point of the Little Ice Age), the overall decrease in hurricane activity and strength is to be expected because of the correspondingly smaller temperature differential between the poles and the equator.
Researchers from the National University of Mexico documented hurricanes in the Gulf of Mexico and the Caribbean Sea from 1749 through 2012 and concluded that the linear downward trend is 0.778 fewer hurricanes per year. Rojo-Garibaldi et al (2016).
We recently discussed here that global major hurricane frequency has been declining for the last 40 years (see Hurricane frequency continues its 40-year DECLINE).
Hurricane expert Ryan Maue also provides the clear data showing that total energy of hurricanes (also known as tropical cyclones), both globally and in the northern hemisphere, is slightly declining over the last 50 years and dramatically declining over the last 30 years.
None of these clear facts, however, stop climate alarmists from continually attempting to misrepresent the exact opposite.
A great example of such an alarmist is Don Lemon who on September 27, 2022 attempted to bully a weather reporter in to admitting that climate change is responsible for the severity of hurricane Ian. Don apparently does not understand the difference between weather and climate, even though the badgered weather reporter (National Hurricane Center Acting Director Jamie Rohme) tried unsuccessfully to educate him. Watch the video clip below.
Here’s the transcript:
Lemon: Can you tell us what this is and what effect the climate change has on this phenomenon?
Rohme: Well, we can come back and talk about climate change at a later time, I want to focus on the here and now [details about hurricane Ian]…
Lemon: Ah, listen I’m just trying to get that you said that you want to talk about climate change, but what effect has climate change had on this phenomenon that is happening now, because it seems these storms are intensifying that’s the question?
Rohme: I don’t think you can link climate change to any one event. On the whole, on the cumulative, climate change may be making storms worse, but to link it to any one event, I would caution against that.
Lemon: Okay, well listen, I grew up there and these storms are intensifying something is causing them to intensify…
