The global warming science facts do not support the climate doomsday scientists' contention that human CO2 emissions are causing dangerous long-term ocean warming - the empirical evidence is 'unequivocal' about this

Doomsday climate scientists would have everyone believe that human CO2 emissions causes long-term climate change in form of "accelerating" warming, especially the oceans. If this were the case, then it should be easy to prove using the global ocean temperature observations from NOAA.
As the adjacent chart depicts, while atmospheric CO2 levels have steadily increased (black dots), the plot of the 30-year change in ocean temperatures (jagged blueish curve) exhibits wide variation.The smooth blue and grey curves represent polynomial fitted trends to the observations, clearly demonstrating that trends in CO2 and ocean warming are not closely related - well, truth be told, they're moving in very opposite directions.
From these opposing trends, one could safely surmise that the correlation between CO2 levels and long-term ocean warming is, in fact, not robust, but rather weak.
Moving on, the red curve is a 5-year average of the long-term temperature change, which obviously indicates the current 5-year average of change being well below previous values, and is now declining. The red curve also reveals that the historical temperature change prior to the 1950's was significantly higher and actually accelerated faster than that experienced over the last three decades (the modern doomsday "global warming").
Conclusions from the actual NOAA empirical evidence: Long-term ocean warming has likely not been a result of human CO2 emissions (a tiny addition to natural greenhouse gases). Long-term modern warming of the oceans is neither dangerous, rapid, accelerating, unprecedented nor unequivocal. Starting around 1998, the modern ocean warming stabilized and slowly morphed into a cooling phase. The global warming science facts are irrefutable, the inconsistent, sporadic long-term ocean warming since the early 1900's does not support the climate doomsday scientists - unequivocally, the empirical evidence mocks them.

Note: The above chart plots the long-term ocean temperature changes (30-year changes). For example, the temperature change datapoint for April 2012 represents the change from April 1982 to April 2012. Likewise, the January 1910 datapoint represents the temperature change from January 1880 to January 1910.
