Biden uses tornado tragedy to further climate agenda: But ‘data shows that these winter tornadoes are not becoming more frequent’ – Climate analyst Paul Homewood: “Provisional data from the NWS indicates that the tornadoes which hit Mayfield, Kentucky and Edwardsville, Illinois were both EF-3s. Although most tornadoes occur in spring and early summer, strong tornadoes are not unheard of in winter. Indeed, on average since 1950 there have been five tornadoes every winter of EF3 and greater strength. And the official data shows that these winter storms are not becoming more frequent:
Despite the latest outbreak, the number of tornadoes this year has been well below average.”No F5 Winter Tornadoes In The U.S. For Fifty Years – Last one occurred in 1971
The US has been hit by six F5 winter tornadoes since 1950, the last ones occurring fifty years ago.

Climatologist Dr. Roy Spencer in 2019: “To claim ‘global warming’ as cause for tornadoes ‘is directly opposite to the clear observational evidence’” – Climatologist Dr. Roy Spencer: “The last half of the 65-year U.S. tornado record had 40% fewer strong to violent tornadoes than the first half. To claim that global warming is causing more tornadoes is worse than speculative; it is directly opposite to the clear observational evidence.”

Dr. Roger Pielke Jr.: “But none of that justifies making obviously false claims about the state of current science, even if made in support of a worthy cause by someone I voted for.”

Here are the facts:
• No overall trend in U.S. tornado activity since 1954; but EF-3+ down 50%.
• Climate models cannot resolve mesoscale features.
• Some enviro conditions may become more favorable in future, others less.
• Low confidence in climate change linkage. pic.twitter.com/G3vYVolpRf

Tornadoes blamed on…Global Cooling! – July 14, 1974 – Lincoln Journal Star – Excerpt: “Droughts, floods, blizzards, tornadoes, typhoons, and hurricanes have plagued much of the nation and the world in recent years. Most people considered these weather conditions to be abnormal and temporary, but instead, climatologists now believe the first half o the 20th century was blessed with unusually mild weather and that the global climate has begun returning to a harsher — but more normal — state. For the long run, there is mounting evidence of a worldwide cooling trend.”

Geologist Gregory Wrightstone: Joe Biden spins tornado misinformation – December 12, 2021 – In 2017, while researching tornado data, I archived the NOAA site’s page on tornadoes and data. At the time, NOAA specifically warned that pre-Doppler radar records of tornadoes (before 1995) are unreliable:
“One of the main difficulties with tornado records is that a tornado, or evidence of a tornado, must have been observed. Unlike rainfall or temperature, which may be measured by a fixed instrument, tornadoes are short-lived and very unpredictable. A tornado in a largely unoccupied region is not likely to be documented. Many significant tornadoes may not have made it into the historical record since Tornado Alley was very sparsely populated during the early 20th Century.”
Because of this, NOAA recommended (at the time) only using the strongest tornadoes as a measure of pre-Doppler numbers and provided this chart that documented an overall decrease in the number of strong and violent storms that were categorized as >EF 3 (I have added the carbon emissions to the chart).
Responding to that article on Twitter, University of Colorado environmental science professor Roger Pielke Jr. described a figure from the article as “incredibly misleading,” pointed out that the rollout of Doppler radar systems increased reporting of very weak tornadoes in more recent years. …
“The rush to attribute the… tornadoes to climate change illustrates perfectly the political distortion of the topic,” climate economist and University of Guelph professor Ross McKitrick told The Epoch Times via email in another exclusive interview. “The IPCC AR6 (Sct 11.7.3) makes no attribution claims between greenhouse gases and tornadoes, and the long term data show no increasing trend in numbers or severity (indeed there is a slight decrease in numbers),” he added, referring to the latest Intergovernmental Panel on Climate Change (IPCC) report on the physical science basis for climate change. “Yet the public has been so primed by politicians and activists to blame extreme weather on greenhouse gases they hardly blink when someone like President Biden just makes up the connection.” “Now the alarmists are shifting to a claim that while the events are natural, greenhouse gases [make] them worse than they otherwise would be,” he told The Epoch Times. “Aside from the questionable statistical analysis behind such arguments, the big problem is that it’s ambulance chasing. The fact that they only ever associate greenhouse gases with bad weather outcomes is meaningless since they only ever look at bad weather events. They never study whether a stretch of mild weather could be attributed to greenhouse gases.”
