The chart you showed is looking at the homeless situation which I think is pretty limited to SF and similar areas, that is, "places you can live outdoors year round which also occur in liberally-run states with lots of access to services for poor people". The unfortunate effect is that creates a magnet for people in bad situations.
I was, full stop, just talking about climate change and the effect it's likely to have here and abroad. In no way do I think that suicide is going to become an attractive option for the average American over that timeframe, but, large swaths of habitable land are going to become inhabitable. NYC will likely survive, at least for my lifetime, because it's the financial pulse of the country and therefore billions or trillions will be spent to keep it floating. But places like Phoenix, where car tires will start popping in the summer sun, and the simple cost of air conditioning will be unaffordable for a lot of people?
There are a lot of reasons I moved to the top of a mountain in a remote town that's practically in Canada, but I'd be lying if I said that thinking about all this stuff wasn't among them.
I disagree with your first comment entirely, and I think the harm done to random scared new sufferers seeing threads like that front and center outweighs any good that can come of them. If someone wants to kill themselves, whatever, not my problem or my concern, but I stand by my original comment.
