Graphs that show unadjusted temperature data are generated by my humble person, using software created by Tony Heller that uses the raw data online from the GHCN (global historic climate network)
A few examples of what is possible with just a mouse click
Many interesting things show up in the actual data, unlike the GISS/NOAA/HADCRUT/BEST "data", which is adjusted, homogenized, corrected and altered so much it no longer resembles actual measurements of weather, but appears as computer modeled "data", that does not match any real set of measurements.
Some examples are extremely obvious, while others are subtle, but all of the "adjustments" make any and all actual weather data appear to be the same, and almost all of it creates an illusion of unusual warming.
I should do an entire blog on just this sort of thing.
