  1. Heat waves have not been increasing in intensity or frequency in the United States. Data from NOAA's Climate Reference Network shows no sustained increase in daily high temperatures in the United States since 2005 when that network began. In recent decades in the United States, heat waves have been far less severe than they were in the 1930s. At that time Heatwaves were more than 6 times worse with greater frequency and covering a larger area than the last decade (EPA). The most severe heatwave year was 1936, and was about 13 times worse than current. This year only 4 US states have achieved higher temperatures than 1936, Arizona was not one of them. Many states in 1936 achieved temperatures 15° hotter than the present. The all-time high temperature records set in most states occurred in the first half of the twentieth century. So far in 2023 (upto 1st August, 2023) the percentage of US Historical Climatology Network Stations reaching or exceeding 95°F (35°C) is at a record low (1895-2023) of 51%. The record high was 1931 at 93%. The trend has been consistently downwards since that point. The climate crisis was 90 years ago. You missed it.
