Victory for climate skeptics, science in the Netherlands…erased historical heat waves get reinstated
The Clintel (Climate Intelligence) reports that the KNMI (the Royal Netherlands Meteorological Institute) has reinstated seven historical heatwaves from the pre-1950 era that had previously been “erased” from official records due to statistical adjustments.

In 2016, he KNMI updated its historical temperature data for the De Bilt weather station (the national reference point). Using a process called homogenization, they had adjusted old temperature readings downward to account for changes in measurement methods and station relocation. This process effectively removed 16 out of 23 recorded heatwaves between 1901 and 1951, leading to the public narrative that heatwaves were much rarer in the past than they are today.
KNMI had overcorrected the data – cooling the past
