Europeans object to being mocked for their lack of air conditioning on the grounds that, pre-Climate Change, there were at most a few weeks per year when they would have wanted to use it. Note that this is partly due to European tolerance for a wider range of indoor temps than we spoiled Americans. They probably wouldn’t turn on A/C until their interiors were 8-10 degrees warmer than what would motivate an American to open up the WiFi thermostat app on his/her/zir/their phone.
Because of American profligacy with fossil fuels, Europe now has brutal heat waves (example from 1911; one that afflicted Paris in 1757) that make their decision to reject A/C appear stupid, but in reality they are the smart/wise ones.
Maybe, however, there is an analogous situation here in the U.S.: should a house in South Florida be equipped with heat? Outdoor temps drop below a comfortable room temperature for only a few weeks per year, analogous to outdoor temps being higher than room temp in Europe for only a few weeks per year. Houses are well insulated in South Florida because they’re almost all new. There is no historical weather that could reduce the indoor temp of a modern South Florida house to a dangerously cold level. Just as Europeans say that they can deal with typical heat by closing shutters, opening windows, jumping in the local canal, etc., a South Floridian without heat during a severe cold weather event could dig through the closet for a sweater and long pants, use an electric blanket or mattress pad at night, etc. Here’s one of the most extreme cold events that ChatGPT managed to find for Miami, which included a low of 28 degrees:
Running heat in South Florida is incredibly wasteful because (1) it is usually a resistive “heat strip” inside the air handler (the latest houses have fully insulated refrigerant lines in both directions and, therefore, heat pump heating capability), and (2) whatever heat is added to the house will eventually have to be pumped back out using electricity for cooling.
What is the observed behavior? Every house, by code, is built with heat capability. People turn on the heat as soon as they feel uncomfortable. As noted above, the latest houses even have heat pumps, maybe due to federal government tax incentives that encourage this super-wasteful-in-south-florida investment ($thousands extra in capital that lasts 15 years to save a couple of $hundred in electricity every few years).
If Climate Change were to cause South Florida to be subjected to a Maskachusetts-style December, Floridians wouldn’t die like the stoic Europeans. Nor would they get into a brawl at Walmart over space heaters. Houses here are already equipped to handle a multi-day freeze. The damage would be limited to higher FP&L bills (still, probably much lower than in MA, though, because rates here in FL are about one-third per kWh of what my friends who’ve remained Righteous are paying!).
As noted above, we could also explain the apparent difference in preparedness as due to a difference in tolerance for discomfort, with Americans being the wimps!
