SST Anomaly – Is Unisys becoming deceptive?

Compare the original method...

to the new method...

Same maps. Same color regions. But they shifted their colors dramatically. The new color system weighs heavily on warm colors. Nearly 2/3rds of the color spectrum is dominated by warm colors. From the old to the new method the yellow color shifts to the left 6 places. The 6 spaces represents a 3 degree shift cooler. So temperatures 3 degrees cooler will be represented by yellow making the map look as if it is dominated more by warmer temperatures.

We've referenced Unisys many times in the past. This is the first time I've seen them play games like that.

  • I think they are trying to explain it here…

    New Sea Surface Temp Anomalies Graphic
    Based on user feedback we developed a new version of our Sea Surface Temperature Anomalies plot with a different color scale. We had been asked to modify the color scale to better differentiate between above and below normal temperatures.

    Please take a look at our new plot and let us know what you think by emailing us at: technical-support@weather.unisys.com.

  • Too bad I don’t buy their nonsense. The original chart best represented the color spectrum. Look at the colors right next to each other at the average mark going plus and minus half a degree. The yellow is bright and obnoxious. It is an overpowering color. They removed five neutral colors to move that bright yellow all the way over to the near normal mark. While leaving that blueish color pretty much right were it was. The idea being obvious. They wanted bright warm colors to dominate regardless of the real state of the ocean. Under the old system more neutral colors dominated the more normal temperatures and the colors got more dramatic the further you want away from normal. That is still pretty much the case with the cold colors but they went extreme on warm colors. If ocean temperatures don’t start improving and we end up in a prolonged La Nina I expect those colors to be changed a bit more. Gotta make people think at a glance that things are worse than they are. This is the hockey stick of color scales.
