Ocean data shows IPCC exaggerates anthropogenic global warming by factor of ~4.6 times

A paper published in Nature Geoscience attempts to explain away Trenberth’s “missing heat” as being “within uncertainty” of the dicey ocean heat content data. According to the authors, “We combine satellite data with ocean measurements to depths of 1,800 m, and show that between January 2001 and December 2010, Earth has been steadily accumulating energy at a rate of 0.50 ± 0.43 Wm−2 (uncertainties at the 90% confidence level). We conclude that energy storage is continuing to increase in the sub-surface ocean.” However, the small “steadily accumulating energy” of only 0.50 W/m2 is far less than even the most conservative estimates from the IPCC AR5 of total anthropogenic radiative forcing. According to the IPCC’s “high confidence” estimates, total anthropogenic radiative forcing in 2011 relative to 1750 was 2.29 W/m2 [range 1.13-3.33]. Thus, Earth is accumulating heat at 4.6 times [2.29/.5] less than the IPCC central estimate, and 2.3 times less than the IPCC lower bound estimate. Thus, the alleged energy accumulation of “0.50 ± 0.43 Wm−2 (uncertainties at the 90% confidence level)” is not even within the IPCC bounded estimates for energy accumulation, therefore, most of the “missing heat” remains AWOL, or most likely, never existed. Further, the fact that Earth has accumulated energy does not imply it has to be from anthropogenic sources. Solar amplification mechanisms, including driving of ocean oscillations, cannot be conveniently ruled out as the source or a contributing source. In addition, the figures below from the paper show the warming rates of the oceans have generally declined since 1993 and since 2001, opposite of the warmist’s claims that more of the “missing heat” has recently decided to hide in the oceans.

Warmist John Cook Says Record Antarctic Ice Is Due To Warmer Southern Ocean – But it ‘has been getting considerable colder since 1981, and particularly in the last 8 years’
John Cook Says Record Antarctic Ice Is Due To Warmer Southern Ocean
By Paul Homewood According to John Cook, Antarctic sea ice has been expanding because the Southern Ocean is getting warmer. He also claims that anyone thinking more ice is due to colder conditions is “ignorant”. He forgets that some of us know how to check the data. Bob Tisdale produces analyses of sea surface temperatures each month, and these have shown that the Southern Ocean has been getting considerable colder since 1981, and particularly in the last 8 years. http://bobtisdale.wordpress.com/2014/10/12/september-2014-sea-surface-temperature-sst-anomaly-update/ All of Bob’s data is sourced from the KNMI website here.
