WUWT reader “Roy” astutely noted that the NOAA SST map shows a lot of hot yellow, in regions which are just barely above normal temperatures. So I tried an experiment to remove all colors between -0.5C and 0.5C anomaly (i.e normal.) The blink comparator below shows the difference. In the original map, the Pacific looks about 50/50. But when the normal temperatures are removed, the Pacific appears colder. The reason being that there are a lot more pixels in the 0 – 0.5 range than in the -0.5 – 0 range.
The video below takes a tour of the earth with “normal” SST’s painted white.
Note that all of the water around Antarctica is normal or below.
