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.

“Wet bulb” is a term that few of us knew a few years ago that is rapidly entering the general lexicon.

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

"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.

>strange

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.

We've had several records this summer as well. Got to 39c at some point. Never experienced that before.
