In a very real sense I'd say this sort of thing belongs in Leopards Ate My Face.
There are a lot of these people who are all of a sudden "Oh, this was not just doomsaying on the part of some radical scientists, this is a real thing." Now that they're actually experiencing the consequences of the last 40 years of complete and total inaction, they are expressing their regret. And, I'm sorry but you all voted for this. You all actively decided to ignore the problem because it was not affecting you at the time. And you didn't really think it would ever actually affect you. And now that it is, you're sad about it. And a lot of these people were even mocking people like Greta Thunberg for her anger at the complete indifference to the global climate crisis we were headed towards. And, to that and them, I say fuck you! We all tried to warn you and you simply ignored us. And now we are all in the same sinking boat together. And for my money, you deserve any and all hardships that you experience due to this climate crisis.
