In The Atlantic today, a journalist asks “When will the Southwest become unlivable?” Yesterday, I perused temperatures in the heat dome over the southernmost part of the (dis)United States. Phoenix, Arizona stood out. The LOW yesterday was 92 degrees Fahrenheit (33 degrees Celsius) at 6a.m. The expected high Saturday is 117 Fahrenheit (47 degrees Celsisus).

Note to the author, the Southwest is already unlivable, at least in July.
