Climate Alarmist Deception Distorting Long Established U.S. Heat Wave Data
Guest essay by Larry Hamlin
The “gold standard” for EPA heat wave established data in the U.S. over the last 125 years is the U.S. Annual Heat Wave Index for 1895-2020 shown below which is Figure 3 from the EPA’s recently modified climate change heat wave indictors website.
The EPA notes the following description of the clearly obvious record high heat wave multi-day extreme heat event occurrences of the 19030s depicted in Figure 3 above as follows:
“Longer term records show that heat waves in 1930s remain the most severe in recorded U.S. history (see Figure 3). The spike in Figure 3 reflects extreme, persistent heat waves in the Great Plains region during a period known as the “Dust Bowl.” Poor land use practices and many years of intense drought contributed to these heat waves by depleting moisture and reducing the moderating effects of evaporation.”
“Figure 3 provides another perspective to gauge the size and frequency of prolonged heat wave events. It shows the U.S. Annual Heat Wave Index, which tracks the occurrence of heat wave conditions across the contiguous 48 states from 1895 to 2020. This index defines a heat wave as a period lasting at least four days with an average temperature that would only be expected to occur once every 10 years, based on the historical record. The index value for a given year depends on how often such severe heat waves occur and how widespread they are.”
