I understand the concept you’re describing but you aren’t applying or understanding it correctly. In fact, California’s climate is dominated by this effect because prevailing winds bring cool oceanic air to the state which is why coastal areas do not get extremely hot or cool. As this air warms across land the humidity drops, so this climate is a bit unique in the way it works but there is typically no extreme heat combined with humidity.
In contrast, the eastern US receives most of its air from dry inland areas, which is why the climate is so seasonally variable. It’s true that the more humid climate does reduce the diurnal temperature swing, and this means absolute maximum temperatures can be lower in many humid climates compared to their arid counterparts. But this ignores that the human body can tolerate dry heat much more effectively than humid heat. So the relationship between aridity and extreme heat mortality is more complicated than it first appears. The most vulnerable places are those that are both hot and humid like the gulf coast, parts of the Middle East, and India. There’s absolutely no reason to think California will be rendered uninhabitable by extreme heat in the foreseeable future.
Look at these figures, you are horendously off the mark with your conclusions here, California is going to continue to be a place where climate change brutalizes people and it sucks :(
Also my argument is explicitly not that baseline environmental conditions are going to wreck havoc on people’s lives in California and rather that in places like California it is the increasingly wild swings in weather that is going to kill and displace people in mass amounts.
I don’t think you are grasping my fundamental point. Most of the time these places will still have nice weather, it is the exceptions and the speed of them that will inveitably cause mass migration out of these areas.
Think of it as living at the bottom of a long slot canyon along a river in the desert but the entire regional climate system is the slot canyon. Most of the time it is a wonderful place to live but the bad days are really bad and the trouble is they come with little to no warning.
