If Manmade Greenhouse Gases Are Responsible for the Warming of the Global Oceans…

…then why do the vertical mean temperature anomalies (NODC 0-2000 meter data) of the Pacific Ocean as a whole and of the North Atlantic fail to show any warming over the past decade, a period when ARGO floats have measured subsurface temperatures, providing reasonably complete coverage of the global oceans?  See Figure 1. Or, in other words, why is the warming of the global oceans (0-2000 meters) over the past 10 years limited to the Indian and South Atlantic Oceans, when carbon dioxide is said to be a well-mixed greenhouse gas, meaning all ocean basins should be warming?

Or, to look at it in yet another way, we’re being told that, while surface temperatures are no longer warming, the oceans to depth continue to warm…yet the warming is not occurring in the largest ocean basin, the Pacific, and the North Atlantic is showing evidence of cooling.

Additionally, Kevin Trenberth and associates say the recent series of La Niña events are causing the Pacific Ocean to warm at depths below 700 meters, and as a result, global warming continues.  See:

Why then has the annual vertical mean temperatures of the Pacific Ocean (0-2000 meters) failed to show any warming over the past decade?  The data for the Pacific Ocean (0-700 meters, 0-2000 meters and 700-2000 meters) in Figure 2 reveals something different than portrayed by Trenberth and associates.

Figure 2

The data for the Pacific indicates that any warming at 700-2000 meters has simply opposed the cooling taking place in the top 700 meters. (Note: The basis for the temperature anomalies at the depths of 700-2000 meters is discussed in the post here.)

ocean-ate-global-warmingNo wonder Trenberth had to use a reanalysis (instead of data) for his recent batch of “hey, I kinda-sorta found the missing heat” papers.

When the data doesn’t meet the climate model-based expectations of the climate science community, the climate science community adjusts the data.  Then, when the adjusted data doesn’t meet the climate model-based expectations of the climate science community, the climate science community discards the data and uses the output of another computer model called a reanalysis.   Bottom line: instead of admitting the hypothesis of human-induced global warming is fatally flawed, they perpetuate a myth.

A QUICK NOTE ABOUT THE VERTICAL MEAN TEMPERATURE DATA

The NODC’s vertical mean temperature data are the temperature component of their ocean heat content data. The other portion is salinity.

Ocean heat content data, and the components that are part of it, are questionable at best, contrived at worst. For further information see:
