The radiative impact of CO2 on the ocean’s thermal skin layer cannot penetrate deeper than 0.01 mm. This effectively eliminates the potential for CO2 to be a driver of global warming.

According to mainstream anthropogenic global warming (AGW) science, 93% of global warming is manifested in the 0-2000 m oceans. Just 1% of global warming is manifested as a change in atmospheric temperature.

Consequently, for anthropogenic CO2 emissions to be a driver of global warming, CO2 concentration changes must drive changes in the Earth’s ocean heat content.

Oceanographers Wong and Minnett (2018) point out that total CO2 forcing can only radiatively exert an impact on the top 0.01 mm of the ocean’s thermal skin layer. (Human hair is about 0.06 mm thick.)

Problematically, the amount of solar radiation absorbed in the upper 0.01 mm layer of the ocean is just 4.9 W/m².

Thus, CO2 concentration changes may, at most, affect 0.049% of the global oceans’ thermal skin layer.

This is the total extent of the radiative impact for CO2 in global ocean heat content changes.

CO2 may therefore be ruled out as a driver of global warming.
