A new fact I learned today and which doesn't make me any happier:

'Survivability was based on what is called "wet bulb temperature" -- a combined metric of humidity and the outside temperature.

When the wet bulb reaches 35°C it becomes impossible for humans to cool their bodies through sweating, hence it indicates the survival temperature for humans. A few hours of exposure to these wet bulb conditions leads to death, even for the fittest of humans'

So a wet bulb condition occurs at 50% relative humidity and 46 °C (115 °F). Many places are reaching that already. Thanks for the tip, I hadn't heard of this.

I can attest to having lived in a place, around 28 years, where the wet bulb got near 30C in the summer that it was quite miserable.
