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'

- aaron695 7y agoNo, you can relax. CNN is lying. The cold kills way more people than the heat, so far, many many more people are alive due to the temperature increase. As to wet-bulb temperature - Peer Reviewed article says 6 hours "probably" would be "intolerable" "Like all living species, human survival is partially a function of the environmental temperature. 35 ◦C is the threshold value of TW beyond which any exposure for more than six hours would probably be intolerable even for the fittest of humans, resulting in hyperthermia. https://doi.org/10.1038/nclimate2833 https://doi.org/10.1038/nclimate2833
- beautifulfreak 7y agoSo 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.
- tmm84 7y agoI 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.
