His disinformation website is called Everything Climate. Translating its stated aim from denier-speak, it is to hook people who aren't yet knowledgeable about climate to recruit them as conspiracy theorists for the climate disinformation cult.
Questionable claims from the outset
Anthony Watts is known in climate science denier circles as a climate science disinformer and conspiracy theorist. True to form, he made a number of questionable claims in his introductory article. He wrote "We have four categories at the moment, and a few dozen sub-titles covering specific claims/arguments that are commonly in the news and are contentious." The bit about "a few dozen sub-titles" is weird, because I can only see 23 articles. I've no idea what the "few dozen sub-titles" relate to. As for the topics he claims are all contentious, some of them are so well-established they are indisputable, some are the topic of active scientific research, and some are strawmen (i.e. the Everything Climate topic is not a claim or argument in scientific circles).
