Alarmist?
Without modern heating and cooling technology half this country is only marginally inhabitable, at least at the kind of comfort and work efficiency level American has grown accustomed to.
I live in temperate, Mediterranean-climate Los Angeles but I spent a year teaching in Sicily, similar climate, and living in an apartment without central heating, A/C, or hot running water. Electricity was too expensive to run a small electric heater, and it was too cold in my room to comfortably sit and, say, read without being bundled up with sweaters and wearing gloves. I sought out restaurants, bars, and hotels to do my prep work. Is this the world you want to go back to?
