That's the ironic part of all this for the supposed "fiscal Conservatives" (which I think is mostly bunk from the start, as they are a-ok with certain spending). We can pay a lot now to try to head off the worst of global warming--or we can pay a LOT more later to deal with the fallout. Key word: later. As in, I'm old and who gives a shit about anything after I die. That's just the ones who admit it's happening, a larger chunk deny it's even a thing. I guess these are all people who don't buy insurance because there is no guarantee they'll have an accident--science is saying it's very likely to heat up, the prudent thing to do is to address it. Nope. That would take sacrifice now, instead we'll just deny and let future generations deal with it. FYGM at its finest.
We as a species are too unevolved to have the tech that caused this in the first place. Then again, iirc the only reason Europe regrew any forests after the Black plague is that so many of us died....they'd mostly cut them all down. So nothing all that new, just on a more serious scale. Agent Smith had it right, we are a virus whose only means of survival is to pillage more area. Unfortunately, we are fresh out of area, so cue the fat lady.
