Yet the science community is happy that we as humans could reverse the ozone destruction and confirms that with correct action we can make an effect upon our environs in a concerted effort.

Checks original source in Nature magazine.

“Here we provide an independent estimate by using measurements of atmospheric oxygen (O2) and carbon dioxide (CO2)—levels of which increase as the ocean warms and releases gases—as a whole-ocean thermometer.”

Reliable – not.

A very much more reliable measure of the total heat absorbed by all the world’s oceans would be sea level rise.

Direct measurements of ocean surface temperatures show that by far the dominant non-seasonal effect is El Nino. Sea surface temperatures are not necessarily representative of temperatures at depth, but with a computer model they would be far more accurate than inferring whole sea temperature increase from measurements of atmospheric gas concentrations.

Or it would be if we had a reliable estimate of how much sea level rise was due to melting land ice.

I’d have thought that estimating ice volumes would be pretty easy, but didn’t someone here have a look at that and conclude that the available data was crap?

We have this problem as well

The Sea Solar Power Plant

Approximately 70% of the earth is covered bywater. In equatorial regions oceans cover nearly90% of this surface segment of the earth. Theseoceans collect and store solar energy. Becausewater arranges itself by temperature and density,the warmest water, being the lightest, is onthe surface. Cold heavier water lies deep below.

A stationary floating plant skims off a smallpercentage of the surface layer to use as theheat source. For the heat sink, the plant hasa large diameter submerged pipe to pump up theheavier frigid water below.

A small amount of heat is extracted from thewarm water and a lesser amount is put into thecold water. The net difference in energy flowis turned into electricity and fresh water and/orfuels and other useful products. Electricityis transmitted to shore through an underwatercable.

A sea solar power electric plant can be described as having 10 major elements. They are (1) boiler; (2) condenser; (3)vapor turbin generator; (4) working fluid; (5) working fluid pump; (6) warm water pump; (7) cold water pump; (8) cold water pipe; (9) electric cable to shore; (10) integrated floating structure.

The warm surface ocean water is pumped to theboiler, which transfers heat to the workingfluid, turning it into a high-pressure vapor.The turbine generator spins as the vapor rushesthrough it to reach the low-pressure condenser,which is cooled by the nearly freezing waterbrought up from the ocean depths. After condensing,the working fluid is sent back to the boilerto be reused and to repeat the cycle.

Pumps are needed to bring the cold water upfrom the deep and through the condenser. Otherpumps move the warm water through the boiler.The power for moving these very large waterflows, plus the power to move the working fluidfrom the condenser to the boiler, consumes about20% of the total power generated (120MW Grossfor 100MW Net).

Err…ooops

UPDATE (Nov. 14/18): Study co-author Ralph Keeling has issued the following statement: I am working with my co-authors to address two problems that came to our attention since publication. These problems, related to incorrectly treating systematic errors in the O2 measurements and the use of a constant land O2:C exchange ratio of 1.1, do not invalidate the study’s methodology or the new insights into ocean biogeochemistry on which it is based. We expect the combined effect of these two corrections to have a small impact on our calculations of overall heat uptake, but with larger margins of error. We are redoing the calculations and preparing author corrections for submission to Nature.
