Until now, heat transport in nanostructured materials has largely been controlled by introduction of atomic - scale impurities, interfaces, surfaces and nanoparticles that reduce heat flow by scattering the phonons diffusely.

Something even the UVic model can more or less do is to demonstrate that you don't get anything remotely resembling the LGM in the tropics and SH unless you include the CO2 effect — though I suspect that the tropical results are very much contaminated by inadequacies in the diffusive representation of heat and moisture transport.

For this purpose, we introduce a heat function which identifies the contribution to the heat transport by different components of the oceanic circulation.

A few things are unequivocal, perhaps (doubling from the present concentration of CO2 will take 140 years [give or take]; the idea that the changes in climate since 1880 have been in the aggregate beneficial; it takes more energy to vaporize a kg of water than to raise its temperature by 1K; ignoring the energy cost of water and latent heat transport [in the hydrologic cycle] leads to equilibrium calculations overestimating the climate sensitivity), but most are propositions that I think need more research, but can't be refuted on present evidence.

It is still popular nomenclature in physical oceanography and atmospheric dynamics to refer to the bodily transport of energy by a fluid as «heat transport.»

As stated above, the wind - driven component is unlikely to change much, and so while the shallow, wind - driven circulations may actually transport more heat (and of course the atmosphere transfers even more), the variability in the heat transport can still be dominated by the variability in the overturning.

Is it not possible that the polar barometric events act as significant pipelines for the re-emission of the ocean entrapped LW in the first three meters, by transporting the oceanic heat content energy for stellar release?

A good way to estimate the effect of the thermohaline part of the heat transport is to shut it down by dumping a lot of freshwater into the north Atlantic in a climate model, which stops deep water formation there.

If the heat transport by the Atlantic thermohaline circulation suddenly increases for some reason (we'll come to that), Greenland suddenly gets warm (an effect amplified by receding sea ice cover of the seas near Greenland) and Antarctica starts to cool.

Global average surface temperatures are not expected to change significantly although temperatures at higher latitudes may be expected to decrease to a modest extent because of a reduction in the efficiency of meridional heat transport (offsetting the additional warming anticipated for this environment caused by the build - up of greenhouse gases).

I agree that most people will not fully understand the implications of this, because most don't know diddly about Hadley cells, Ferrel cells, the Polar cell, albedo, latent or sensible heat, and mechanisms by which solar energy can be transported from the Arctic to melt more of the Greenland ice sheet.

As far as I know, if the only physical mechanism under consideration is the radiative cooling of the planet's surface (which was heated by shortwave solar radiation and reradiated at longer wavelengths in the infrared) via radiative transport, additional gas of any kind can only result in a higher equilibrium temperature.

I believe that cooling by adding trace amounts of a gas to an atmosphere is physically impossible under the assumption that only radiation physics is responsible for heat transport which is what the guy was arguing.

Theory and modelling suggest that if the sinking of the salty surface waters in the North Atlantic slowed down or stopped, there would be a reduction in the heat transport by the ocean, which would have implications for the climate of northern Europe.

Actually, there is some interesting work being done by Matt Huber of Purdue, following up on some earlier ideas of Emanuel's, suggesting that the role of TCs in transporting heat from equator towards the poles may be more significant than previously thought — it also allows for some interesting, though admittedly somewhat exotic, mechanisms for explaining the «cool tropics paradox» and «equable climate problem» of the early Paleogene and Cretaceous periods, i.e. the problem of how to make the higher latitudes warm without warming the tropics much, something that appears to have happened during some past warm epochs in Earth's history.

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.

Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep water formation should have little effect on the physics of the gyre and the formation of the western boundary current, and it also seems the tropical warming and the resulting equator - to - pole heat transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?

If tropical cyclone occurrence decreases, less of the heat is dissipated, and unless ocean circulation in some way compensates by transporting the additional thermal energy elsewhere (i.e. for example out of the «main development region» of the Atlantic) some day a storm will tap the enhanced energy source.

Re 40 simon abingdon — there is very little mass loss to space (can be significant for evolution of conditions over geologic time or in more extreme conditions, but not for Earth like conditions over the timescales over which climatic equilibrium is determined), and latent and sensible heat are transported by conduction and convection and mass diffusion, which can't significantly extend outside the atmosphere.

Scientists are still trying to decide how the poleward heat transport will be affected by global warming — but the rapid changes at the poles seem to involve a lot of heat transport into that region via both the atmosphere and the oceans.

Dynamical upward transport by convection removes excess heat from the surface more efficiently than longwave radiation is able to accomplish in the presence of a humid, optically thick boundary layer, and deposits it in the upper troposphere where it is more easily radiated to space, thereby affecting the planetary energy balance.

To the extent that the flow of «heat energy» is a part of that process, by means of conduction (collisions between molecules), and convection (physical transport of molecules), the second law insists that the natural direction of that flow is from «hot» to «cold».

These processes affect the transport of water, heat, salinity, nutrients and carbon in the ocean, impacting on the climate system by modifying it's ability to absorb human - emitted carbon dioxide and excess heat resulting from increased carbon dioxide concentrations.

The notion of an H2O positive feedback (which probably is present on a clear day) is squashed by this process.While warmer air can hold exponentially more water vapor, presumably increasing greenhouse effects (an process the IPCC hangs its collective hat on), it is also this exact same property that vastly improves the chances of convective and phase change heat transport by thunderstorms.
