Official Data Refutes Climate Alarmist Heatwave Claims

There were a few days of hot weather in the US a couple of weeks ago. ‘Scientists’ immediately said it would have been ‘virtually impossible’ without attributing it to ‘climate change’
It’s the same old, unsubstantiated claim that gets wheeled out every time it gets hot. And every time they ignore the lessons of history.
If heatwaves are caused by global warming, what caused them in the past? Not only have they always occurred, they were considerably more severe in the past in the US.
In 2017, the US Global Change Research Program published the Fourth National Climate Assessment, a report mandated by Congress. It can be seen here repository.library.noaa.gov
Running to 400+ pages, it was an extremely detailed, fully referenced assessment of the US climate and how it had changed over the years. Chapter 6, “Temperature Changes in the United States”, included this section on temperature extremes:



The evidence was unarguable. By all measures, heatwaves in most of the country, with the exception of the west, had been considerably more severe in the past.
Conversely the same was true of extreme cold – that too had been more severe in the past.
Bear in mind that we are not talking about an isolated phenomenon, the Mid-West dustbowl years. The heatwaves of the 1930s were a national event, not a regional one, and were not confined to one summer.
Indeed the heatwaves of the 1910s, 1920s, 1950s and 1980s were all memorable. These findings were embarrassing to say the least. I recall at the time an attempt to bury them by excluding them from the Executive Summary.
In 2023 the next edition, the Fifth National Climate Assessment came out with the same message:

These two reports are now buried in the archives. They are no longer available from the usual public sources.
Thanks to my old links and Wayback though, I have now managed to download both from the NOAA Institutional Repository.
