GWPF Exposes EPA Deception in New Climate Change Heat Wave Index
Guest essay by Larry Hamlin
The Global Warming Policy Forum (GWPF) published a comprehensive article addressing new U.S. EPA (Environmental Protection Agency) climate change indicators allegedly made to inform science-based decision-making but instead found that many of these indicators are misleading, deceptive, incomplete and based on selective data.
The GWPF article specifically addressed recent shenanigans by the EPA involving its heat wave climate change indicators which supposedly portray heat wave frequency in the U.S from 1961 to 2019 as shown below.
The GWPF notes the heat wave frequency data presented by the EPA (red data on the left) is misleading because it shows (without specifically identifying as such) minimum not maximum temperatures across 50 American cities. The GWPF data (blue data on the left) shows the maximum temperatures which greatly reduces the heat wave frequency derived from the 1960 and beyond period.
Additionally, as noted by GWPF the EPA data excludes the prior global cooling period from 1940 to 1970 thus exaggerating the warmer period that occurred after that time and more significantly ignores the extensive and searing heat of the 1930s period.
