Title: Humans can't endure temperatures and humidities as high as previously thought
Post by: rcjordan on June 30, 2022, 02:52:49 PM: 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.

A major wet bulb event is what kicks off The Ministry of the Future (vaguely on my list, but have not read it)

Post by: rcjordan on July 16, 2022, 03:01:36 PM: "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."

Max/Min Temperatures:
88°F - 70°F

Total Precipitation:
0.00 in.

Max/Min Relative Humidity:
100% - 55% (95- 80% most of the daylight hours)

Temps have been slightly lower here along the coast this summer. Mostly mid-80s. Which is odd. The interior of NC has been baked, though. But humidity here has been high for longer periods during the day. I saw some farmers and outdoor workers at the mega-farm restaurant yesterday ...they were suffering. I worked on a mower deck much of the day and had to set up a big fan outside.
