Okay, we might get to 2.5 degrees, but the economy!
This will go on until we get to around 5 degree and most parts of the world have become uninhabitable and most animals and vegetation has gone extinct and we've locked ourselves in perpetual wars due to water and food shortages. Sounds like a shitty B movie, but this is what I truely believe we will end up with.
If it makes you feel any better, once it gets that bad, society will eventually break down and our CO2 levels will naturally return to normal over the next several centuries while the Earth is reclaimed by nature as we go extinct.
I’m hopeful economies and governments will collapse before 3 degrees and measures will be put in place. I’m not extrapolating a utopian future. Before we get to the point where the world reacts, there will be many wars, migration and fascism. But as it gets worse, I’m hopeful groups will work together and fight for a better future.
Nah, what will happen is that said incompetent governments will be replaced by incompetent dictatorships that will just tell people over the barrel of a gun that things are better now.
