Buy some property next to or on the great lakes, like in Michigan's upper peninsula. Hawaii and many, many coastal areas of the US will be underwater in the coming decades as oceans rise. A lot of climate crisis aware folks in the know are saying the great lakes will geographically be one of the best places to ride out the oncoming catastrophe--it's well enough inland yet also near a huge source of fresh water. It's also a gorgeous place that isn't a total tourist trap.
