9. And this is at only 1C of warming

In 30 years, we'll be at 2C.

In 50 years, pushing 3C.

Even with rapid decarbonization of human civilization, we're starting to see positive feedback loops activate that will turn the Arctic, Siberian and North American taiga forests, and the Brazilian rainforest into carbon sources, emitting billions of tons of carbon on their own now. And industrial carbon sequestration isn't going to cut it.

When you start adding up all the massive economic blows we'll be seeing on a regular basis in 20 years, the odds of societal degradation and/or collapse start to go up rapidly. A billion dollar flood here, a billion dollar fire there, a crop-withering drought or two taking out breadbasket regions of the planet and causing food shortages regularly, rising sea levels flooding major cities, and pretty soon you've got large numbers of angry, hungry people on the streets or moving North, demanding relief that financially strapped governments can't provide any longer. And that's also fertile ground for authoritarian and fascist regimes to take root.
