I worry more about a couple Nukes going off and ruining all the GPS etc stuff. People get used to stuff gradually. Roads being fixed that sort of stuff too. Our Generations faced challenges, so will our Great Grand Children. They will do their best most likely. Some will still be homeless too. Maybe the massive movement of populations away from seacoasts to higher ground / making barriers, will be the largest challenge.
Looking at high tides and Tsunamis. It's most likely easy to foreplan for all the harsh weather events and the expansion / effect to /of the peoples affected. The Lowlands of Earth maybe unlivable most of the time passable by boats. Places like the Smokies leveled for large building sights. Inhabitable like normal. One can notice it already happening, even along the cliffs of the river Valleys.
Growing up a Rural Farm Boy and watching the Creeks flood several times a year taught me to always live at or near the top of a hill.
The Big City, Burbs bunch know no better than to live low elevations. Jobs etc. many in flood plains.
Basically 100' above flood / high tide has been my belief. Most likely the Future level will be 200' above flood / high tide if I were to live to 200 years of age. Around 2014 I looked at a home in the Florida Panhandle. 24' above high tide. Walked away, it will all flood most likely many times.

Even the Gov. tries to hide stuff. Most likely the strain on the people will be much worser than we can imagine. Of course the flash floods are nothing like a large River flooding for a month and a half. But adding that to the High sea Water at the wrong times and the River Valleys become uninhabitable for months also when the Levies are breeched / topped. Mississippi, Louisiana, East Texas, even some of Arkansas in
deep H2O.
Sure, the future is all doom and gloom. Nothing has changed.
