I'm currently living in the PNW and people are struggling with 18F. Why? Because this entire area is built around a temperate climate. A lot of house have single pane windows and no insulation. Most people don't have AC (so the extreme heat kills). We will adapt, but it's going to take people waking up to the new reality.

So have I but extended dives into negative °F are new and very unfun. We might have had one day every other year that went -3 or so but for the last week almost it's been 0 or -15 no real in-between and the road salt my city uses is better for your car but doesn't have enough oomph to go much below 10°F.
