Climate change is the underlying problem, but most of the "doomed" feeling I've heard from others comes from the inevitable strife that will follow widespread climate displacement, famine, drought, and other increasingly severe weather. Not to mention feuding governments. My feeling is that we could survive climate change easily, but it's the other people that will do us in. We've lost ~4.5 million people globally to covid and things have been a little weird (this is certainly an understatement for some). What happens when that's 50 million? 100?
