“Urban areas are over represented and there are large areas of the earth’s surface that are not measured, not to mention instrumentation issues and many other factors.”
There is a website with photos of weather stations and how their surroundings have changed. Like how 20 years ago it was in the back yard of the fire station surrounded by grass. Now it sits in an asphalt parking lot between the old station and the new 2-story building.
I have a photo of the ones at the new “Environmental Education building at our zoo. The building is partly into a hillside, grass sod roof, etc. The weather station is in the fenced-off gravel area 10 feet from the three large A/C structures fro the building!
They’ve been installing weather stations on top of heat islands for decades. A frigging airport is NOT going to tell you what the temp is 30 miles away, nor is it going to give an accurate representation of the mean areal temp in a given geographic region. I studied this in college. I do ongoing online coursework with NOAA. I’m a grad NWS storm spotter. It’s a lifelong hobby. I’m no certified meteorologist or atmospheric scientist, but with my background, I can tell you that we’re being mushroomed. Global Whining extortionists should be tried, convicted, and thrown naked onto an ice floe.
