On a more personal note.
At 32.5 c & 97% humidity I today experienced an >32 c wet bulb temperature.
It was a new daily high for Cambridge, but only by 1.5 c. The humidity was unusually high, and in the evening rain finally arrived. I'd lived in the American Southwest desert for decades and have experienced much higher temperatures, but not with this humidity.
When Canadian weather gets within 3 c of the 35 c wet bulb that kills within hours, how many more years before the southern states become unlivable?
My solution was to leave my air conditioned apartment, pick up my car from my air conditioned parking space, drive to the beach with the A/C on high, then wait until the rain cooled things off.
