He made his name pouring scorn on the siting of US temperature stations - he being a former weatherman, and all. He announced (using Glenn Back or some such as his platform) a programme of Station Siting investigations that was going to show up those Warmy Alarmists once and for all.
Much ado, and many blog posts, later, Anthony's "investigations" made the light of peer reviewed publication. First irony is that a bona-fide climate scientist John Nielsen-Gammon had to be brought in to clean up the math.
Secondly, the paper proved the very opposite of what Anthony had proclaimed it would: station siting had NO effect on the overall temperature measurements, a result later confirmed by Richard Muller's BEST team.
So here's to Anthony Watts - a man with one peer-reviewed publication, and the only climate science denier to be his own debunker!!!

Mean temperature trends are similar at poorer sites due to the contrasting biases of maximum and minimum trends
