If you're at all capable, purchase property up north. You can get acres of undeveloped land for a few thousand dollars. If you can, have an ongoing project to get some basic services set up on the land like a secure shed to cover a well and a solar kit. Get an RV or a van and just know that if shit falls apart you can drive out there and at least have water and power. Wireless or satellite internet would be a good idea.

The coming disasters are going to take a number of years to ramp up, it will probably happen slowly enough that people will almost literally be the toad boiling to death as the heat slowly rises. It could be a few years, it could be a few decades. Whatever happens, it will happen and it will get worse. We're going to see the most drastic change to our world that anyone has ever seen and a lot of people are going to suffer and it's going to happen at the same pace which we read about school shootings, annoyance and impatience.

Most of us won't be able to afford land and even if we do move to cooler, less unstable areas, we still may have to deal with food shortages, economic crashes, and social instability. It's not going to be like The Road, we're not going into a sudden world of cannibals and post-apocalyptic fashion choices, it's going to be a long slog through more and more discomfort, storms that don't let up on coastal cities, political drama as people try to move or get federal help, refugees swamping places that can't handle the numbers, authoritarians trying to seize power, crime and looting in the aftermath of storms, cities slowly becoming abandoned as the flood waters never get a chance to recede, as happened in some parts of New Orleans as long ago as Katrina.
