This summer has seen the highest global mean sea surface temperatures ever recorded. Temperatures even exceed those of the record-breaking 1998 El Nino year.
Figure 1: a) NOAA Sea Surface Temperature anomaly (with respect to period 1854-2013) averaged over global oceans (red) and over North Pacific (0-60oN, 110oE-100oW) (cyan). September 2014 temperatures broke the record for both global and North Pacific Sea Surface Temperatures. b) Sea Surface Temperature anomaly of September 2014 from NOAA's ERSST dataset.
