Prior to 1960, June 17 was typically a very hot day in the US. But since 1960, June 17 has been much cooler than the first half of the 20th century.
The ten hottest June 17th’s in the US were 1936, 1952, 1913, 1921, 1944, 1918, 1957, 1933, 1994 and 1897. All but one were below 350 PPM CO2. Prior to 1960, an average of 26% of stations were over 90F on June 17. Since 1960, that number has dropped to 20%.
The summer of 1936 was the hottest on record. On June 17, 1936 there were 90 degree temperatures in almost every state, and a huge swath of the country was over 100 degrees.

June 17, 1936 was the beginning of an incredible heatwave which lasted through the end of September. It was 105F at Seymour, Indiana that day.
Seymour had eighty-six days over 90 degrees in 1936- but now they average fewer than fifteen 90 degree days per year. The frequency of 90 degree days has plummeted over the last 80 years.
This week in 1988, James Hansen appeared before Congress, announced the “beginning of the greenhouse effect” and said his computer model predicted an increase in heatwaves and drought in the Midwest. He said he was 99% certain.

Since Hansen made that forecast, both heatwaves and drought have nearly disappeared from the Midwest.

Some scientists were taken in by Hansen’s BS in 1988 – but many recognized that his computer models were not actual science.
James Hansen is the leader of the global warming movement, and he has absolutely no clue what he is talking about. The climate has done the exact opposite of what he predicted.
The global warming scam persists decade after decade, despite all evidence to the contrary. Hansen’s temperature data was fake, and Gavin Schmidt has made it even faker.
