I made this map of sea surface temperature (SST) trends at the GISS website module, and it shows the 27 year trends 1979-2005 for an SST dataset GISS names HadReyn_v2 which I take in to mean the Hadley Centre version 2 SST’s with Reynolds data grafted on post 1982.
There may be another explanation of exactly what the dataset is but for sure it is the SST data Jim Hansen’s GISS group chooses to use.
I have annotated several warm anomalies that caught my eye and have compared UAH satellite trends over those warm patches with the the combined land sea HadCRUT2 data calculated at www.co2science.org.
See the Table for stunning differences in HadCRUT2 minus MSU, up to 1 degree C in 27 years !! The table also sets out the Lat & Long for various five degree grid cells that include these warm SST patches. For some history of the development of the SST datsets go to my page showing graphics of huge corrections required in raw SST data.
