Now compare that to the actual GHCN thermometer data which the graph is based on. They look nothing alike. The 1930s were much hotter.
The next graph overlays the published GISS temperature (red) on the thermometer data (blue) normalized to 2003. You can see that they have massively cooled the past relative to the present – to create the appearance of non-existent warming.
Next, let’s compare the actual data to what GISS published in 1999, before they started their most serious tampering.
The next graph overlays the thermometer data (blue) on the 1999 GISS graph. You can see that there was much less tampering going on at that time.
The next graph is a bonus, which overlays…
