You may be right. I keep assuming that Western politicians are smart people who are playing dumb for the public so that they can keep their grifts going. But they may not be playing in many cases. That might explain the rather sluggish response to what looks like a very serious crisis unfolding over the next 1-3 decades.
It’s underappreciated how much of a story this is. This is happening in wide swathes of the USA. Big chunks of the West are abandoned, because of wildfires, earthquakes, etc and all along the Gulf Coast as well, including big chunks of Florida (which tons of people have moved to in recent years).
