But wouldn't a closer model be the first order ODE, where the difference between absorbed solar power and lost black body power has to equal the change in temperature with respect to time multiplied by the terrestrial and atmospheric combined heat capacity:

Assuming all other things are equal then I would expect that a shutdown in the THC would lead to more heat transport by the atmospheric circulation as the temperature gradient would be greater.

The atmospheric greenhouse effect, an idea that authors trace back to the traditional works of Fourier 1824, Tyndall 1861, and Arrhenius 1896, and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system.

The natural process of atmospheric blocking, and the climate impacts induced by such blocking, are the principal cause for this heat wave.

It is quite a strong La Nina, and that is a forcing of the atmosphere by the anomalous atmospheric heating patterns linked to SSTs [sea surface temperatures].

The vast majority of research in recent decades on the carbon dioxide buildup has been focused on the atmospheric impacts of the accumulating greenhouse - gas blanket even though the vast majority of the heated trapped by these gases has gone first into the seas — and the drop in seawater pH driven by CO2 has been a clear signal of substantial environmental change.

This would have an effect on both atmospheric and ocean circulation and heat balance that would have to be modeled by detailed ocean / atmospheric climate modeling.

There's been much discussion recently of quick, cheap steps, with many benefits, that could slow warming driven by the atmospheric buildup of heat - trapping greenhouse gases.

OLR increases in the optically thinner bands would lead to atmospheric warming in general, but this has to be accompanied by OLR decreases somewhere, such as in optically thicker bands (and always in the band where optical thickness was added, assuming positive lapse rates everywhere as is the case in a 1 - dimensional equilibrium model with zero solar heating above the tropopause, or at least not too much solar heating in some distributions), which will tend to cause cooling of upper levels.

At atmospheric pressures and as a liquid conversion to heat by collision wins.

The radiative balance over equilibrium timescales — the heat released by raindrop formation will locally warm the atmosphere, but it takes time for the atmospheric circulation to average this out.

Thus, if the absorption of the infrared emission from atmospheric greenhouse gases reduces the gradient through the skin layer, the flow of heat from the ocean beneath will be reduced, leaving more of the heat introduced into the bulk of the upper oceanic layer by the absorption of sunlight to remain there to increase water temperature.

I hadn't heard about the heat transport via the atmosphere, but it didn't surprise me — that is what the jet streams are all about — a wind caused by an atmospheric temperature differential, given a little bit of a spin.

Ingraham also states that the most important aspect of weatherizing your home is to receive a «post audit» by a certified energy auditor to make certain your heating appliances (boiler, furnace, atmospheric hot water heater, etc) are drafting combustable gases properly.

Starting with zero atmospheric LW absorption, adding any small amount cools the whole atmopshere towards a skin temperature and warms the surface — tending to produce a troposphere (the forcing at any level will be positive, and thus will be positive at the tropopause; it will increase downward toward the surface if the atmosphere were not already as cold as the skin temperature, thus resulting in atmospheric cooling toward the skin temperature; cooling within the troposphere will be balanced by convective heating from the surface at equilibrium, with that surface + troposphere layer responding to tropopause - level forcing.)

Moreover, the atmospheric temperature gradient is mitigated by the absorption of solar radiation within the atmosphere (also latent heat deposition), thus a more moderate temperature gradient is established within the ral atmosphere.
