It already is. I have a Zoom call with several clients in Germany, and they're always sitting in their offices with a fleece pullover on. It's my guess that they're all keeping their thermostat settings way down to afford the little heat they've got, as energy prices have gone through the roof.
I heard a funny joke a little while ago.... What did Socialists use before candles? electricity.
I sure wish that "ice age" would come to Fla. I'm sick to death of still sweating my ass off in Dec at Christmas. It's just not natural. I'm here 30 years and I'll never get use to this smoldering, humidity, hell all year long.
