Too narrow when merely questioning whether: Is the increase of CO2 warming the ocean because of the radiative properties? Or are the state of the oceans a product of many things, the sun a primary driver?

The question should instead be based on the current ocean structure and physical mechanism. What impacts have the various human marine activities from shipping, and fishing to off-shore installations? Any activity may warm or cool the sea surface, which immediate or long term impact on the state of the atmosphere. After all the sea-surface temperatures (SST) are only warm in a very thin layer, while the ocean total average is only about +4° Celsius.
