2c is only locked in if we do nothing. We can actually keep it lower, but it requires rethinking things.
Listen, I’m going to explain something in a way that is not fearmongering nor hyperbole.
3c would be disastrous. No, it won’t make the planet like Venus, but it could cripple society. The strip of the Earth from the equator to around both the tropics would soar to temperatures in-conducive to human life. Over a billion people live there currently, where do you think they’ll go?
When real, actual scientists say that a 3c increase is catastrophic, we are not doing so to fearmonger. We are not saying it will lead to extinction, nor a Venus Earth. But, the world it leaves in its wake is not a pretty picture.
