"How not to measure temperature, part 35"

Another update from Anthony Watts is here.

Excerpts:

Here we have a USHCN station in the middle of a junk pile. Old storage crates and containers, a rusty metal trailer, and a disabled Winnebago. Most curiously, one piece of junk, a discarded solar mirror, has the potential for heating up the thermometer more than a few degrees under certain conditions. It’s hard to believe, but this is exactly how I found the site.
...
Note how the solar mirror is pointed right at the shelter, under some sun angles, I’d wager that this reflects sunlight directly on the shelter.

It seems very likely to me that over the last century, the bulk of the recorded warming here had absolutely nothing to do with carbon dioxide.
