That's basically what I'm saying - the US massively overproduces food. There's many problems with how it's done and how it's used, but the Americas aren't likely to starve. So long as the US stands, starvation isn't likely - we literally burn crops to keep production at a level where we could feed much of the world

Climate refugees aren't murderhobos - they're people. People that will mostly without a job, often living out of their cars, and largely desperate. They need just as much to survive, but desperate people do desperate things. The ones that aren't desperate will integrate, the ones who are will be a burden on the system

Let's say Florida or Texas start bleeding population. Almost nowhere is equipped to handle 5 million more people in a short time frame - it would wreak havoc on the job market, strain supply chains, and lead to a massive increase in crime. Desperate people do desperate things

Yes, it's our current problems magnified. There is enough to go around, but not like we do it today. We have to restructure the world - will we do it today, while we have breathing room, will we do it in a decade, when our systems fall apart around us, or will we do it decades from now, when the choice is between sacrifice and death

Climate change is here - it's a right now problem. If we give it time, it could collapse everything - if the US collapses entirely, a famine in Toronto is a possiblity. Every city could starve. I don't think we'll get to that point, but there will be death. There is already death. The sooner we start to address reality, the less suffering our species will undergo

I don't think humanity could die out unless Earth becomes another Venus. We're too adaptable, too widespread for that. And if we've already lost, who cares. It's a pointless line of thinking. We could be screwed, but I don't think​ we are...I think the Earth trends towards a stability humans can live with. I think we have more systems balancing us, if we go down that road it'll be a slow and painful one we won't live to see

This is a problem that will affect you, it will affect everyone. We can minimize it - many will die no matter what we do. But most could survive, but only if we change the systems at play - I think we'll get there, but the question is how much suffering we endure before then
