I disagree. These cities have vast amounts of solar power to the point that they could, with storage, not only self sustain on mostly just rooftop solar but could perhaps even be net energy exporters. They’re also not in areas likely to be inundated by flooding, and they are not in places where their expansion destroys forests. They are low density today too meaning they have tremendous room to build up. Lack of freeze thaw cycles means roads and buildings last longer, reducing energy use in constant repair and CO2 from constant reapplication of concrete and asphalt. Water is their big problem but with cheap renewable energy that problem is solvable either with pipelines or desalination. Lastly air conditioning takes less power than winter heating in extremely cold climates and like I said above is more easily fueled by renewable energy. Solar generation peaks exactly with A/C demand. Cities up North tend to burn tons of fossil fuels for heat and that is harder to decarbonize. Heat pumps help but it’s still more intensive than A/C. If the water problem is solvable these cities could become far more sustainable than say New York or Chicago due to all their cheap solar.
