Global warming, how it is done

[jeep78]

Checked the "official" government reported temp this morning before going outside. The weather station is 1 mile from my place. It was reporting 27 degrees F in real time. I went outside and could tell something was amiss. Over 1 inck solid ice on the stock tank, and both outside thermometers showed 17 degrees F.

One or 2 degree difference is understandable, but not this.

These data collection points were sited near heat sources, plain and simple. It is a widespread scam, and similar observations have been made all over, esp in liberal areas.

Stay warm.

Yep, with this cold we've been having I've noticed that the temperatures have been running constantly lower than the listed one's.

Oh, that's easy. Now, any variation in weather is claimed to be evidence of "climate change". Too wet, too dry, too cold, too warm, too many hurricanes - all claimed as proof. Maybe that's why the left has moved towards the phrase "climate change" instead of "global warming". The latter was far too restrictive for their agenda.

Most "official" weather stations were established at airports.
Back then, airports were often way out from cities (for obvious reasons).
As cities grew, many airports wound up in more and more built-up areas.
It ain't easy to move an airport, or find new sites (even ignoring resident complaints about noise, traffic, etc.).
So weather reporting stations went from, essentially, in-the-middle-of-nowhere to in-the-middle-of-the-city. Conditions are much different.
Comparing wide-scale weather reporting over time is not easy.

And, of course, satellite weather reporting was a whole lot less accurate a hundred years ago ().

Anthony Watts (WattsUpWithThat.com) did an informal, but fairly well-controlled study where people sent in pictures of government temperature monitoring stations. It wasn't just airports. In some cases, you had thermometers situated next to black top parking lots, exhausts from building HVAC systems, and in one particularly ironic case...a burn barrel. Widespread problems with the "temperature network."

Government scientists' excuse: "We adjust the data for errors." Only problem with that excuse is that they never seem to adjust data downward. Only up.

In the meantime, if you look at the satellite temperature record maintained by the UAH, while it shows warming over the last 50 years, it generally stays within a fairly narrow range.

It's an exercise in control and mass delusion, with trillions of dollars and individual liberty as the stakes.
