Are July 2012 Sea Surface Temperatures for U.S. Coastal Waters Also At Record Levels?

The map in Figure 1 shows the July 2012 sea surface temperature anomalies, based on NOAA’s ERSST.v3b dataset, for the coordinates of 24N-50N, 130W-65W.

Figure 1

We’ll use those coordinates for the sea surface temperatures (not anomalies) of the U.S. Coastal Waters in the following two graphs. Figure 2 illustrates the July sea surface temperatures for those coordinates from 1854 to 2012, and Figure 3 shows the annual (ending in July) sea surface temperatures for U.S. Coastal Waters from 1855 to 2012. I’ve also plotted the July 2012 value in Figure 2 and the value for the period ending in July 2012 in Figure 3 to simplify your task of comparing the most recent temperatures to the earlier values.

Figure 3

The sea surface temperatures of U.S. Coastal Waters are nowhere close to being at record levels for the month of July 2012 or the 12-month period ending in July 2012. I’ll let you decide (speculate about) what that means with respect to the claims of unprecedented U.S. land surface temperatures in July 2012.

My priority is finishing my book about ENSO and its multiyear aftereffects. I’ve only got a few more chapters to write and then I’m done with the first draft of Who Turned on the Heat? The Unsuspected Global Warming Culprit, El Niño Southern Oscillation. Then I have to go back and read the 500+ pages to see what I wrote.


The map and the data presented are available through the KNMI Climate Explorer.
