I have no idea why David chose to post this rather pointless article.
For readers' information, what this article calls the "wet-bulb
temperature" is what is normally called the dew point. Dew point is a
measure of absolute humidity. It was traditionally measured using a
so-called wet-bulb thermometer, and in conjunction with the air
temperature (measured using a regular, or "dry-bulb" thermometer), the
relative humidity can be calculated, which is what is more prominently
mentioned in weather reports.
If a wet washrag, for instance, is left out to cool by evaporation, then
it will cool down no lower than the dew point. The same process cools
humans/animals when they sweat. Thus when a rising dew point approaches
body temperature, one's body would warm yet further as if they had a
fever. More than a few degrees of fever is fatal.
That was the entire point of this article. And that is why the article
is pointless: a rise in global temperatures of 10 degrees C that the
article contemplates is so beyond an absolute disaster that talking
about it is a distraction. Climate activists are working to prevent a
rise of more than 2 degrees over several decades, with a 3 degree rise
already seen as disastrous. After reading about a 10 degrees rise, the
actual concern with a 2 degree rise seems trifling. Such talk more
belongs in the realm of science fiction, not climate science.

"Today the most common maximums for wet-bulb temperatures around the
world
are 26 to 27 degrees Celsius. Wet-bulb temperatures of 35 degrees
Celsius
or higher are lethal to humanity.Above this limit, it is impossible for
humans to dissipate the heat they generate indefinitely and they die of
overheating in a matter of hours, no matter how hard they try to cool
off.
“So we were trying to get across the point that physiology and
adaptation
and these other things will have nothing to do with this limit. It’s
the
E-Z Bake Oven limit,” he said. “You cook yourself, very slowly.”
