It’s time to uncover the truth about NOAA’s annual tornado scam:

The frequency of tornadoes in the United States has been steadily increasing since the 1950s, according to NOAA's latest annual report. For the casual reader, this is obviously due to global warming, which we all know makes weather more extreme!
Their report fails to mention that we are now observing more tornadoes because of better technology and reporting procedures, not because more tornadoes are actually occurring. This is a guide that NOAA published a few years ago, but has now mysteriously disappeared from their website. Thanks to Wayback, we can still view it.
One of the major difficulties with tornado recording is that a tornado or evidence of a tornado must be observed. Unlike rainfall or temperature, which can be measured with fixed instruments, tornadoes are short-lived and very difficult to predict. If a tornado occurs in a sparsely populated or deserted location, it is less likely to be recorded. Many major tornadoes may not make it into the history books tornado alley The population was very sparse in the 20th century.
Much of the early work on tornado climatology in the United States was done by John Park Finley in his 1887 book Tornadoes. , but the book remains a seminal work in the field of tornado research. The University of Oklahoma has created a PDF copy of this book and makes it available at: John Finley's Tornado.
Today, nearly all areas of the United States are densely populated, or at least covered by NOAA's Doppler weather radar. Even if a tornado is not actually observed, modern damage assessments by National Weather Service personnel can discern whether a tornado caused damage and, if so, how strong it might have been. This discrepancy between past and currently recorded tornado records introduces considerable uncertainty into questions about the long-term behavior or patterns of tornado occurrence. Improved tornado observation methods have led to an increase in the number of reported weak tornadoes in recent years EF-0 tornadoes become more common among total number of tornadoes reported. Additionally, even today, many smaller tornadoes may remain unrecorded in places with sparse populations or unreliable communications facilities.
The number of tornado reports has increased over the past few decades as national Doppler radar coverage has expanded, the population has increased, and more attention has been paid to tornado reports. This can create the misleading appearance of a trend of increasing tornado frequency. To better understand changes and trends in tornado frequency in the United States, one can analyze the total number of EF-1 and stronger and strong to severe tornadoes (EF-3 to EF-5 categories on the enhanced Fujita scale). These tornadoes may have been reported even in the decades before Doppler radar became widely available, a practice that led to an increase in tornado reports. The bar chart below shows that the frequency of stronger tornadoes has changed little over the past 55 years.

.
In fact, as of 2014, the number of severe tornadoes did decline, not what NOAA calls a “minor trend.”
We now have complete data for 2023, so I can expand on the two graphs above:

Little has changed since 2014. The latest data confirms NOAA's 2015 conclusions.
There were no EF-5s last year and there are none so far this year. The last one was the Moore tornado in 2013. The EF-5's previous longest absence was from 1999 to 2007.
And there were only two EF-4s last year. Only 2005 and 2018 had smaller numbers.
The evidence clearly shows that tornadoes have weakened in intensity since reliable records began in 1970, but NOAA wants you to believe that's not the case.
It's hard to argue that NOAA's reporting of tornadoes is fraudulent.
