Flashback: Levitus et al 2000 and Ocean Heat Content – an Oceanographer’s critique

In a recent paper, “World Ocean Heat Content And Thermosteric Sea Level Change (0-2000), 1955-2010″ commented upon by Roger Pielke Snr at his science blog,  and by  Willis Eschenbach at WUWT, Levitus et al have continued the theme they started in 2000. A critique of that first paper was written at the time by oceanographer Dr Robert Stevenson, now deceased.

“Contrary to recent press reports that the oceans hold the still-undetected
global atmospheric warming predicted by climate models, ocean warming occurs in 100-year cycles, independent of both radiative and human influences.”

Contrary to recent press reports that the oceans hold the still-undetected global atmospheric warming predicted by climate models, ocean warming occurs in 100-year cycles, independent of both radiative and human influences. 

At a press conference in Washington, D.C., on March 24, 2000, Dr. James Baker,  Administrator of the U.S. National Oceanic and Atmospheric Administration (NOAA),  announced that since the late 1940s, there “has been warming to a depth of nearly 10,000 feet in the Atlantic, Pacific, and Indian Oceans.” “In each ocean basin, substantial temperature changes are occurring at much deeper depths than we previously thought,” Dr. Baker said, as indicated by research conducted at NOAA’s Ocean Climate Laboratory. He was referring to a paper published in Science magazine that day, prepared by Sydney Levitus, John Antonov, Timothy Boyer, and Cathy Stephens, of the NOAA Center. 

For 15 years, modellers have tried to explain their lack of success in
predicting global warming. The climate models had predicted a global temperature increase of 1.5°C by the year 2000, six times more than that which has taken place. Not discouraged, the modellers argue that the heat generated by their claimed “greenhouse warming effect” is being stored in the deep oceans, and that it will eventually come back to haunt us. They’ve needed such a boost to prop up the man-induced greenhouse warming theory, but have had no observational evidence to support it. The Levitus, et al. article is now cited as the needed support.
