During the record hot and dry summer of 2011 in Texas, Katharine Hayhoe determined that it was the new normal, and that the number of 100 degree days was going to go through the roof.
In fact, the exact opposite is happening. The number of 100 degree days in Lubbock has been declining since the 1930s.
The average summer maximum temperature has also been declining.
And summer precipitation has been increasing.
Katharine Hayhoe cherry picked a single outlier, and declared it to be a trend. Junk science doesn’t get any worse than that.
