My friend in Seattle has been having the same issue for several years. Very few homes in Seattle have A/C and thanks to global warming their summers have been getting extremely hot. She had to sleep on her front porch a few years ago because it was too hot inside her house. It was above 100 degrees!
Another of my friends there just had her house remodeled. Her husband said they decided to install A/C because a couple of years ago they had to stay in the house and keep the windows closed due to the smoke from the fires in Western Canada.
I've seen the temps in the Northeast and Midwest this weekend and they are unbearable. Very few good choices to live these days when it comes to extreme climate.
