Why we're all going to die

almost 20 percent of electricity consumption in U.S. homes goes to AC -- that's as much electricity as the entire continent of Africa uses for all purposes.

Basically, large parts of the US would be uninhabitable were it not for air-conditioning. The same goes for Saudi Arabia and several other places.

It has allowed us to put cities in very fragile ecological zones like the desert area where Phoenix is, or the fringes of the Everglades, or actually out into the Everglades now in South Florida. We build up these big Sun Belt cities on the assumption of air-conditioning, so there's limited green space. The heat island effect becomes pretty overwhelming -- all the asphalt, concrete, and steel are trapping heat that's then released throughout the night. In Phoenix you can easily have a lot of nights where the temperature never drops below 90, while in the normal desert climate you get a big drop in temperature.

Until we get sensible and abandon Texas, we'll just have to accept that the Western lifestyle will sink islands and drown poor brown people. We're too selfish to do anything about it, like change our way of life or adopt clean technology. Changing costs money. The status quo only costs lives. Other people's lives, which appear not to count.

I see your point, I really do... but if Texas were to be abandoned, then there'd be a hell of a lot more Texans running loose in the world, and I think that changes the implications of your proposed solution

Well, perhaps we simply give Texas back to Mexico and make Texans their responsibility.
