First at Twitter, aspiring meteorologist Chris Martz posted a chart of tornado activity since 1954. Contrary to what climate alarmists have claimed, tornado frequency has not trended upwards:
Hurricane claim involves “massive error”
While on the topic of violent weather, the Washington Post recently published another alarmism-fraught article on the alleged increasing strength of hurricanes due to global warming and how there’s now a “slower decay of landfalling hurricanes in a warming world.”
“Says it shows hurricanes decaying slower over land post-landfall (more damaging). But they forgot to remove storms that landfall & then go back over the ocean,” Pielke tweeted.
In the Twitter thread, Dr. Ryan Maue pointed out that some of the hurricanes plotted were not “a typical example” of inland hurricane decay.
No real trend
Examining global landfall cyclone data since 1970, There’s no observed noteworthy trend: Dr. Ryan Maue also tweeted a chart on tropical cyclone activity over the past 50 years:
Declining in some regions
The often heard claim of more frequent and intense cyclones is not supported by the data. Another paper by Zhao et al from 2018 in fact shows Western North Pacific cyclones becoming less frequent since the start of the century.
Moreover, data from the Japan Meteorological Agency (JMA) show that the number of typhoons formed since 1951 has trended somewhat downward:
So it’s a mystery as to why the Washington Post and Nature would create alarm and make false claims over tropical cyclone activity. That’s science no one should consider, let alone follow.
