The problem with this attitude is that it prevents you from solving problems that might actually affect the odds of humans making it to tomorrow or any other near-term date. Right now it looks as if we're in the run-up to World War III. [0] Perhaps we should spend a little energy preventing that. Or perhaps aquifer exhaustion, a long-standing issue exacerbated by climate change. [1] Or solving the political polarization that prevents us from addressing other problems. [2] Humans have faced all of these problems in the past and generally solved them.
Climate change is obviously a serious and challenging problem. But it seems doubtful civilization will be directly overturned any time soon by climate change alone. Europeans and others made it through crises like the Black Plague, which killed a third or more of the population without extinguishing the arc of civilization. [3] It's the knock-on effects we need to worry about, as well as the things that prevent us from fixing them.
