“If the facts don’t fit the theory, change the facts.”
- Albert Einstein
Einstein was just joking, but that is exactly what the Climategate team has done to the surface temperature record.
We have all grown used to seeing graphs like the one at above from NASA, showing nearly continuous global warming over the last 135 years – with a flat period between 1940 and 1980, and 1.2C warming from 1880 through 2000.
Much of climate science, journalism and public policy is based around the belief that these NASA graphs are an accurate representation of the temperature record, and that the apparent warming which is shown in the graphs is due to an increase in atmospheric CO2. It is therefore very important to understand the accuracy, consistency and integrity of these graphs.
However, if we look at earlier versions of the same graph, we see something very different. The graph…
