When I was younger, I worked exclusively on a v220 (best of the worst) Unix terminal using vi to write programs in c/c++. Yeah I got a little fancy near the end of that with three separate terminals, but the point was I also had memorized an absolutely ridiculous amount of information starting at the syntax rules for four somewhat related languages (bash, c, c++, and whatever the fuck makefile's are) plus hundreds if not thousands of functions in c and c++ without needing to consult documentation or rely on autocomplete to fill in the blanks.
30+ years later I have a command palette tool I absolutely depend on along with degraded typing skills that show whenever I have to type something out completely like a peasant.
Consider the ages of those involved, they will be long dead of natural causes by the time the true "find out" stages of climate change has really gotten going. Also they've got wealth & privilege so will have the easiest time migrating to safer places.
Even now, Phoenix Arizona is still another 3 years, at least, away from when evacuations will need to start while Vegas has maybe another 8 as long as the deeper water lines work as designed. Miami could defy the somewhat impossible odds and survive another decade before a hurricane wipes it out like Andrew did to Homestead. Yes bad things are starting to happen faster now, but we could have had another decade of some semblance of normalcy.
