You can move thermometers a short distance and get warmer readings. I can move mine around my yard and see a rise of 5 degrees easy. We are to take the word of something we have no personal knowledge of how these reports are being propagated, and if it's non partisan. The slow down of rising temperatures is being ignored.
Nobody, least of all the professionals of the world's weather/meteo services (like Jáchym), are "moving" the mutha effen AWOS/ASOS's instruments around to bias the WX data readings, in order to fulfill the feverdreams of the world's climate denier nutcases.
There are very strict
siting protocols for positioning official meteorological instruments. And non-professional ones like ours,
if you'd just read, for example, the CWOP guide, or even the one packed with your WS.
You can even verify the positioning of almost any WX instrument worldwide by either visiting it yourself (easy enough for local airports, etc). They are seldom moved.
Or by using some of the greatest instruments yet devised:
satellite images, often freely available from many sources; you can get a WS's L/L and pull up a map/chart/satimg and zoom right in to it.
Verify it yourself. Using factual, objective data and methods. Just like the pros do (well, not quite, they are far more accurate, and they have to run that ol' "peer review" gauntlet).
BTW, those satellites, and all of our other NOAA/NASA/etc stuff is perhaps some the best, highest use of our tax dollars there is (urkurk, will not take cheap shots...).
I use sat images often, one use is to compare my charts and eyeballs with them, for nav aboard while underway (some of the nice, more modern than mine, chartplotters integrate stored or real-time access sat images (of varying age of course), very nice, I just use a tablet or laptop).
And 'planning' ahead for a Pacific voyage (maybe...). Also to follow TIGHAR, one of my fav (small) time sinks, checking out Nikumaroro/Gardner Island.
