Is 450 ppm (or less) politically possible? Part 0: The alternative is humanity’s self-destruction
At 800 to 1000 ppm, the world faces multiple miseries, including:
Sea level rise of 80 feet to 250 feet at a rate of 6 inches a decade (or more).
Desertification of one third the planet and drought over half the planet, plus the loss of all inland glaciers.
More than 70% of all species going extinct, plus extreme ocean acidification.
