From the paper:

> Richard S. Lindzen was Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology until his retirement in 2013. He is the author of over 200 papers on meteorology and climatology and is a member of the US National Academy of Sciences and of the Academic Advisory Council of GWPF.

Does meteorology count as "atmospheric science"?

Does climatology count as "climate change" or "climate modeling"?

Does 200 papers count as "published papers"?

Does being a professor at MIT count?

By your own criteria, he is an expert.

Therefore, by what reasoning do you dismiss him?

Religion.
