I have good understanding of physics on relatively small scale systems. Fundamentally, oceans are a huge heat sink- a truly high thermal inertia system. The relationship/interaction/forcing elements between large bodies of water and the atmosphere is obviously a complex one. I don't profess to have a deep understanding of the linkage/relationships between the atmosphere, currents, and warming/cooling of large bodies of water. That is super large scale stuff. It's like an electrical engineer claiming to have a profound understanding of large scale electrostatic energy- i.e. lightning. A totally different ballgame.
