From a gut-feeling/statistical projection standpoint, the current state of fossil fuel use increases does not bode well for any kind of adaptation scenario except maybe the "retreat" scenario. The question of "where" is going to be the definitive paradigm for the 21st century. The next most important question will be "how many people?". The human race has demonstrated its blindness to the vulnerability of high population density in our willingness to pretend that we didn't know millions would die from COVID-19 under the lassaiz-faire economic morality of ("don't stop the cashflow") Marketmania.

Now, most of the economic powers-that-be are pushing for MORE fossil fuel-based infrastructure projects to enable the See-Wall-See-Nothing projects like your example, as well as to 'recover' from COVID 'slowdown' and 'put people back to work' at useless jobs wasting precious resources to make shiny noisy crap and take trips to places nobody needs to go (Sportsball, anyone?).

At this point, I recommend studying up on migratory lifestyles (on foot) and knowing where the fresh water sources are going to be.

Unless, of course, the other scenario manifests itself (the halting of the ocean haline circulation and freezing of northern lattitudes.)

I give everyone about a 80/20 chance of either collapse by heating or by cooling, but either way involves massive dieoff and economic catastrophe.

Meanwhile, nearly every single municipality, investment bank and civil authority is behaving as though nothing is going to change drastically because the citizens don't want too much to worry about unless it means they get to buy more stuff at "Always Low Prices".
