I wrote a one-page document with 12 enumerated paragraphs titled “Why Global Warming/ Climate Change is a Hoax.”   I emailed the document to about 15,000 college teachers in the U. S. The Chairman of the Science Department at Nassau Community College emailed me back and said that I did not know what I was talking about and should take Prof. Cohen’s course on climatology. I replied that I would if I could distribute the document to my potential classmates.  I got no answer and filed a freedom of speech lawsuit that was dismissed by the district judge. I filed an appeal and requested oral argument. My request was granted and oral argument was held on October 15, 2020.
