Anthony Watts was for years the chief meteorologist for channel 12 newsChico/Redding. He was also first to poke huge holes in climate change and global warming data.
A classic story about a temperature monitoring station feeding the system regular high temperatures in Orland, CA Watts investigated and discovered that the station the entire California State University system had been using was at the Orland fire station, a monitor 5 feet off the ground. Turns out the fire chief parks his pickup truck nose first within inches of the monitor. Which of course is heated by the chiefs hot radiator.
Just one example from Anthony Watts book which destroys global warming data collection.
