The interesting thing is that remote thermometers that haven't been
changed in 60 years stuck out well away from civilization show no
warming at all....
It's thought to be the unstated reason why 75% (possibly 5000?) of the
GHCN's network of thermometers have been taken off the data supply,
leaving only those that support the narrative of 'global warming'.

This is just a lie on a lie. Numerous studies, including ones with a 'sceptical' origin, have shown that rurally sited thermometers show warming, and it's not as if there isn't considerable effort in siting and bias correction to account for urban heat islands. It is of course easy to find individual thermometers that show you any trend you want by cherry picking localities - but aggregate lots of data and the message is consistent.

As for 75% (possibly 10,000) GHCN thermometers being offline? Another obvious and simplistic lie. For a start GHCN contains data from over 100k stations, not the 14k that is implied. Active daily readings are received from over 20k stations. The data can be reviewed and inspected so the implication that sites are removed for 'unstated' reasons is rhetoric. And GHCN is just one line of evidence for global warming - we have satellite measurements, observation of melting glaciers, sea level rise, simple physics. In fact one study looked at over 170 diffrent surrogates for temperature - things like coral growth, isotopic composition of water - guess what? Confirmed the trends.
