Comparison graph: GISTEMP/cccpng46 KB
Goddard Institute for Space Studies Surface Temperature Analysis (GISTEMP) results in red, and Clear Climate Code (CCC) ccc-gistemp results in blue. We have lowered the ccc-gistemp line by 0.2 degrees Celsius for clarity, otherwise it would be hidden by the GISTEMP line. The green line (right-hand scale) shows the difference between the two sets of results.
