I have come across a simply wonderful animated representation of the
number of thermometer locations worldwide since 1701 in the Global Historical Climatology Network (GHCN) database by month.

It is produced by a Turkish researcher, SinanUnur
Be patient while watching, it last 4 minutes. It is very slow to show any change at first since there were very few thermometers in the first century! Note the mass of stations in 1951 to 1980 (GHCN baseline period) and the subsequent decline. Ask yourself, for example WHY has Canada been virtually denuded of stations? Answer: the stations are still there, recording data. However, most of the data collected isn't used in any of the averages, models or projections. Cherry picking at its finest.

Surprisingly, you will still find AGW conformists arguing that this decline in station numbers plus extreme selectivity is hunky-dory and that all is well in the GHCN gmt measurement world. I don’t think so.
Sinan states
“I do think it important to show that the averages are not being calculated using a fixed set of observational units.”
Thanks to Sinan. His work, started in 2007, adds weight to the research into GHCN by EM Smith at Musings from the Chiefio here chiefio.wordpress.com/category/ncdc-ghcn-issues/ here and Verity Jones here at diggingintheclay diggingintheclay.wordpress.com/
Here is another informative animation from Sinan showing how the cool and warm adjusted stations (blue and red segments) vary over time as a proportion and numerically of the total stations incorporated in the gmt calculation. Brill!

I take it that the cool adjustments (I assume of historical data) and the warm adjustments of recent readings is to create the illusion of an exaggerated rising trend in the purported period of AGW 1970 onwards.
