The summer of 2023 is cooler than usual, as the graph shows. Nonetheless, the climate change chorus claims that this summer is worse “in profound ways,” and there are computer models about hypothetical climate “tipping points”—not “documentation” of actual occurrence. For perspective, Phoenix had 18 consecutive days of 110° temperatures in 1974, and Death Valley hit 134° in 1934. The six hottest July 19ths in the U.S. occurred in 1934, 1932, 1936, 1930, 1926 and 1901—when almost half of the US was over 95 °F (35 °C). Atmospheric CO2 levels were much lower then.
