@ai6yr There is high danger of a mass #casualty “wet-bulb event” in Turkey and elsewhere that hit 50 C high temperatures! The chart in the attached picture show the relationship between temperature and relative humidity. Short story: very high temperatures and even moderate humidity will kill you because you can’t cool your body core by perspiration. That’s the red area in the chart. Human physiology varies; that’s why there is a wide yellow line. How long you can survive is also a variable. With the #ClimateCrisis , it is question of when — not if — a #wetbulb catastrophe will occur. Anyone caught without A/C in one of those areas will die if it lasts very long. Is this what will stir people into action? A fictional, but scientifically accurate, depiction of a wet-bulb event is the first chapter in “Ministry of the Future” by Kim Stanley Robinson.

@ai6yr How hot is too hot? A good explainer about #wetbulb temperature.

What is wet-bulb temperature? And how hot is too hot?

Yes, thank you. Please see also the Wet Bulb Globe Temperature which accommodates sun angle, wind, clouds.

If you have Obsidian with the math community plugin, I think this is right.

```math
T = 30.2
RH = 81.0

WB = T * atan(0.151977 * sqrt(RH + 8.313659))+ 0.00391838 * sqrt(pow(RH,3)) * atan(0.023101*RH) - atan(RH - 1.676331) + atan(T + RH) - 4.686035
