Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.

At that point in geological history, global surface temperatures were rising naturally with spurts of rapid regional warming in areas like the North Atlantic Ocean.

The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

In the case of warming caused by a disproportionate increase in atmospheric CO2 (compared with oceanic CO2), an increase in temperatures only slows down the rate at which CO2 is absorbed by the oceans.

Increased warming of the cool skin layer (via increased greenhouse gases) lowers its temperature gradient (that is the temperature difference between the top and bottom of the layer), and this reduces the rate at which heat flows out of the ocean to the atmosphere.

(The actual equilibrium takes on the order of a few thousand years, the mixing time of the oceans, to reach... But that's at constant temperature... So if the oceans warm significantly, then we lock in a new equilibrium, at higher atmospheric CO2 for much longer timescales.)

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentiTemperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differentitemperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

@ 48 If your speculation is correct, I assume that another consequence would be that, if / when concentrations of greenhouse gases start to drop, corresponding reductions in surface ocean / land temperatures would take place at a much slower rate than would otherwise be the case: the surplus heat stored in the deep ocean will gradually make its way to the ocean surface, and continue to warm the atmosphere for decades, if not longer.
