Extreme heat limits safe activity for millions of people worldwide
Extreme heat is now stopping people from doing simple daily tasks like walking, cleaning, or working outside.
A new study shows that climate warming has changed how much activity the human body can safely handle in hot weather.
Scientists found that since the 1950s, the number of hours each year when heat becomes dangerous for normal activity has increased sharply.
Yesterday it got up to 79℉, in Illinois, in early March. That is not normal. I rely on cool spring temperatures for yardwork such as planting bare-root trees and shrubs. I had to start my summer heat-coping skills, like avoiding direct sunlight and reducing workload. Plus we had to turn on the damn air conditioner, because recently when it was 76℉ outside, the house got considerably hotter and stayed that way through the wee hours. >_<
Summer, of course, has days when I can only go out for a few minutes at a time or not at all, and I worry about the air conditioner breaking because repairs take months to complete. It's life support for me, but other people don't consider that urgent.
