Attacks on scientists and their research are very common in the public debate surrounding global warming. The attacks don’t need to make any sense nor is there a need for merit to the raised criticisms. For climate science deniers it’s more about maintaining their ideological mental armour so they can keep their world view in tact.
In this arena two papers by Stephan Lewandowsky stand out by the sheer tenacity and vitriolic nature of the attacks. The paper NASA Faked the Moon Landing − Therefore, (Climate) Science Is a Hoax: An Anatomy of the Motivated Rejection of Science was, and still is, relentlessly attacked for the inconvenient results it contains.
