Jones and Ricketts:
“We propose that there is negligible in situ atmospheric warming and that almost all of the added heat trapped by anthropogenic greenhouse gases is absorbed by and stored in the ocean. It is subsequently released through the action of oscillatory mechanisms associated with regime shifts. Most heat (long-wave radiation) is trapped near the ground or ocean surface and much of that is radiated downwards (Trenberth, 2011). The atmosphere as a whole has little intrinsic heat memory and does not warm independently of the surface.
This is supported by observations on land where the overpassing air mass takes on the characteristics of the underlying surface, achieving energy balance within a 300 m distance (Morton, 1983). When passing from land to water, this will see all of the available heat energy taken up by water if the temperature of the air mass exceeds that of water (Morton, 1983, 1986), with the temperature of the overpassing air mass reaching equilibrium with the water beneath within a very short time. Very little of the heat trapped over land can be absorbed by the land surface, but will be transported from land to ocean within a few days to a few weeks, where it can be absorbed (the high latitudes being an exception).”
