The trend is not just for June 11, but for the entire month of June, and for the entire year.
The US has been record cool over the past nine months, and the green area should expand with the cool weather forecast for the eastern US.
We now associate 100 degree weather with the desert southwest, but it used to be quite common across much of the country.
The hottest June in Phoenix was 1974, when they averaged 109 degrees for their afternoon temperatures, and were over 110 degrees for eighteen consecutive days from June 12-29. I played on the soccer team at ASU that year, and we practiced at 3PM every day.
That was also the peak year of the 1970s ice age scare.
As atmospheric CO2 has increased, the frequency of hot days in the US has plummeted. The peak year occurring below 310 PPM.
Meanwhile, the useful idiots in the press continue their usual mindless hysteria about things they understand nothing about. They simultaneously forecast heat, drought, fire and floods – i.e. the same weather we have always had. And they tell their readers that the same weather which has been occurring for hundreds of millions of years can be prevented by climate action.
