researchers found that the actual maximum wet-bulb temperature is lower — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.

"About a fifth of the human population was just subjected to almost unimaginably long-lasting extreme heat, and the ultimate toll, if we can accurately assess it, will tell us quite a lot about how some of us might suffer through the future climate.

If the current pattern continues to hold, with fuller calculations showing a still relatively limited impact, five hypotheses provide at least partial explanations: problems with data; the dryness of the heat wave; local adaptation and response; that the hottest parts of the world may already be relatively acclimated to extreme heat; and that our casual use of “wet-bulb” readings may be misleading about actual mortality risk."

Except for a week to 10 days of around 90 degrees (like in June), this has been a very mild summer, which is strange.

July 2022 was highest on record in Austin, TX. Average daily high of 103.8
