Summer doesn't officially start until tomorrow, June 20, but much of the U.S. is under a dome of high-pressure, hot air that has us cooking. This photo was taken downtown yesterday afternoon. 100 F is about 38 C. I think it was 119 F / 48 C in Phoenix on Thursday. Most - but not all - of us have air conditioning, but then think of our substantial homeless population. There are cooling shelters here but it's not unusual to hear of low income elderly people dying in their roasting apartments.
I'm sure we will revisit this in a month. Maybe less.
