It seems that those who fear AGW (or at least some of them) do admit that it is not realistic to expect a planetary atmosphere such as ours to warm up oceans of water over the timescale required by AGW theory because of the huge volume and density of that water and thus the heat storage differentials.

Though hurricanes strenthen when moving over warmer water, this is merely due to the fact that the horizontal temperature gradient of the atmosphere is not as steep, i.e. the temperature differential between the water and the atmosphere increases as the storm hits tropical waters; it is not the ocean temperature per se that drives the hurricane.

The authors postulated that this warm salty water (WSW) layer, situated beneath the colder surface freshwater in the North Atlantic, generated ocean convective available potential energy (OCAPE) over decades at the end of HS1.

A2) The Sun is the source of all this energy as it is the hottest thing around, and by the greenhouse explanation above the GHGs redistribute insolation into the ocean until their heating from above and the tendency for warm water to rise once again cancel each other out and the new stable (w.r.t. averaging over 24h) vertical gradient is attained.
