You talk like +10C is nbd. Are you aware of how much landmass was covered by water during that time?
I'm no expert but that would cause human civilization to take a dramatically different form if not outright extinction.
- wheelerof4te 3y agoNo, I'm saying that 420 parts per million is still much lower than 3000-9000 parts per million. Also, even a number they chose is plain trolling. Of all numbers, 420 ppm is what they "calculated".
