Guess I can help most people outside US reading these unfamiliar strange numbers;
Earth first avg temp: 22,78c
Then 26,67c, “even” 32,22c.
Todays avg: 15,56c.
If you're gonna dig into the geological record, the Hadean eon was hot enough that rock at the Earth's crust was still entirely molten.
How did people manage 55M years ago when it was 73F and 500M years ago when it was 80-90F?
I think I know what you're trying to point out, but just for anyone who doesn't get it - humanity has been around for about 200,000 years.
How is this relevant?
"Dumb" life has survived and flourished on Earth at much higher global temperatures. Smart life (humans) should certainly be able to figure it out.
