The BBC’s Climate Check is unsurprisingly about hurricanes, and equally unsurprisingly does not tell the truth:
Ben Rich repeats the BBC’s frequent lie, that climate change is making hurricanes stronger, expressed of course in the usual “scientists say” way. These are his exact words:
“Climate scientists believe that global warming is making them stronger”
It is of course true that some scientists say this, but equally many hurricane experts maintain the opposite, something you might have thought the BBC would have reported.
And, given this is supposed to be a “Climate Check”, you might have thought the BBC would actually have provided some facts, rather than just opinions. The IPCC were quite clear in their last Assessment Review, AR5:
They could find no evidence whatsover of any “significant observed trends” in tropical cyclone activity over the past century. All they could find was an increasing intensity of North Atlantic hurricanes since the 1970s, which hurricane experts such as Chris Landsea believe is part of the multidecadal cycle, the AMO. This is borne out by the fact no that robust trends in major hurricanes has been found in the North Atlantic in the past 100 years.
Little has changed in the latest AR6, which can still find no long term trends.
One particular omission in the video is the role of wind shear, high level winds which act to break up hurricanes. While Rich mentions this factor, he omits to tell viewers that scientists believe that global warming will increase wind shear.
This Climate Check has little to do with facts, and is little more than propaganda.
