One of the many things I appreciate about Anthony Watts is his bringing to everyone’s attention the reasons for the poor surface temperature data that’s being used to stoke the climate alarmism.
Check out just three of his examples. Many times these were stupidly set up ( in parking lots, by pavement, near heat exhausts, etc).
Other times, they were set up correctly, but times change (and construction changes the monitoring).
