Insurance companies are starting to abandon whole counties and states where the risks of climate change induced hurricanes or forest fires pose to great a risk for them to consider providing coverage any longer. Try getting a mortgage when you can't get disaster insurance.
All the ignorant haters saying we should "just move" will be the first ones crying "but not to MY town" when we do. Enjoy paying all those extra taxes when your own property values skyrocket.
@Agatha As climate change continues to grow stronger a good portion of currently habitable land, across the planet, is going to become very dangerous, or impossible, to live in. People will have to move.
Unfortunately, if the money isn't there, people still won't be able to move.
