In 2021, the physicist and New York University professor Steven E. Koonin, who served as undersecretary for science in the Obama administration's Energy Department, published the best-selling Unsettled: What Climate Science Tells Us, What It Doesn't, and Why It Matters.
The book attracted extremely negative reviews filled with ad hominem attacks, such as a short statement appearing in Scientific American and signed by 12 academics that, instead of substantively rebutting Koonin's arguments, calls him "a crank who's only taken seriously by far-right disinformation peddlers hungry for anything they can use to score political points" and "just another denier trying to sell a book."
