I am completly opposed to Air-conditions propagandized as a solution to climate change. What is the wright approach to combating this state of temporary relief except from old-fashioned fans? Don’t get me wrong. They do the job for me. I am reffering to finding a solution for people more with health issues or large facilities that are in need of something more drastic.
In 2021, the polar vortex caused sub zero temperatures in northern Mexico. It was -7 in Monterrey. You don’t deal with -7 with just layers and blankets.

i have dealt with sub zero in a sleeping bag in an Adirondack (building with 3 walls, basically outside)
