First there was global cooling. Then, every prediction they had for that was wrong. So then they came up with global warming, fucking up all the global cooling offsetting the next ice age. But then every prediction they had for that, was wrong. Now they're just like I don't know what the fuck is going on man, shit is just changing.
Personally, I don't give a fuck what the climate does. We'll be able to colonize and ruin the rest of the universe before it becomes a problem.
The real threat to humanities existence on this planet, aside from ourselves, isn't the fucking weather. You should be more concerned with the destruction of the root system that was holding this continent together. That's the reason giant sink holes are appearing all over America, more so than ever before.
