Just a physics, my dear Watson. Thermal capacity of oceanic water is roughly 5.000 times higher, then the thermal capacity of atmosphere. Furthermore, the main source of heating is just a surface. When surface is heated, the so called convection occurs in atmosphere, because hotter air tends to circulate in vertical direction.

But at the case of water in ocean exactly the opposite effect occurs: the heating of surface layers effectively inhibits the existing underwater convection, for example the thermohaline convection, which drives the Gulf stream.
