The interesting thing is that remote thermometers that haven't

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.

I suggest you go to te root research and re=thgen read what I siad
carefully.

Its not just rural siting, its that the same thermometer is in use in te
same way.

And it hasn't been 'normalised'

Or changed from '#average' to 'halfway between daytime high and night
time low'

Yuss ffolks. One man with a portable Dyson hairdrier can create a
'record temperature' in a town near you...

Teh raw satellite record shows bugger all warming going on.


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.

I think you should check your facts agian
