People often make the nuclear war comparison but it's different. With nuclear war, we just have to hope that a couple hundred people are sane enough to not push the button. In comparison, with climate change, it seems like the vast majority of older (and much of younger) generations simply don't care that the status quo is going to screw us. Also consider the fact that a private corporation (Exxon) had all the knowledge to give us enough lead time to avert this situation and decided to make piles money instead, and it gives you a pretty bleak picture of humanity.
