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.

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.

It's responsible for transporting heat all over the ocean and regulating weather patterns in places like Europe and eastern North America.

Reduction in ice free area, a positive feedback to the atmosphere increases poleward ocean heat transport, a negative feedback for the oceans.

Moreover, changes in models often affect climate simulations in ways that are understandable in physical, real - world terms; increasing an ocean - model's resolution, for example, makes the simulated Gulf Stream stronger, and thus enhances heat transport to the North Atlantic.

The reason for the decline in sea surface temperatures at these locations is because of the reduced heat transport along the ocean surface from the tropics - where solar heating is most intense.

This has nothing to do with heat transport into the ocean, although that phenomenon, in my view, also supports fairly high sensitivities once the evidence for significant rates of deep ocean transport are factored in (but that's a different topic).

Conversely, during low solar activity during the Little Ice Age, transport of warm water was reduced by 10 % and Arctic sea ice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibility?

This is wrong — the ocean takes up a huge amount of heat in the tropics and does indeed store it and transport it (e.g. to the north in the Gulf Stream) where it contributes mightily to the moderation of the climate of Europe, for example.

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).

The oceans play an important role in the earth's climate; they transport heat from equator to pole, provide moisture for rain, and absorb carbon dioxide from the atmosphere.

While the circulation of the Atlantic Ocean has a complex three - dimensional spatial structure, the zonally integrated flow in the basin, referred to as the Atlantic Meridional Overturning Circulation (AMOC), is largely responsible for the net northward oceanic heat transport on climate - relevant timescales.

A commentator on the ClimateAudit thread has asked Gavin Schmidt, in a comment submitted to RealClimate, whether temperature and net flux data for GISS - E2 - R available via the CMIP5 portals and KNMI Climate Explorer are based on a model corrected to fix the ocean heat transport problem.

Associated with the warming, there has been an enhanced atmospheric hydrological cycle in the Southern Ocean that results in an increase of the Antarctic sea ice for the past three decades through the reduced upward ocean heat transport and increased snowOcean that results in an increase of the Antarctic sea ice for the past three decades through the reduced upward ocean heat transport and increased snowocean heat transport and increased snowfall.

Since latent heat transport (and surface cooling of the ocean) must increase in proportion to the rate of evaporation, perhaps Wentz et al have identified a reason why the models appear to overstate climate sensitivity: the actual latent cooling increases by about 4 watts per square meter more than the models predict for each degree rise in surface temperature.

Perhaps the model results do open a door for Arctic geoengineering approaches though, for instance by influencing Arctic Ocean salinity and heat transport or through Arctic solar radiation management.

Northward ocean heat transport achieved by the AMOC is responsible for the relative warmth of the Northern Hemisphere, compared to the Southern Hemisphere, and is thought to play a role in setting the mean position of the Inter-Tropical Convergence Zone north of the equator.

For example, Holland et al. (2006) related simulated rapid ice loss events to anomalous ocean heat transport into the Arctic from the North Atlantic.

My impression is that you think that «self - propelling» climate «trends» (something nebulous to do with changes in ocean heat transport occurring for no known reason) are an alternative explanation for modern warming.

The basic results of this climate model analysis are that: (1) it is increase in atmospheric CO2 (and the other minor non-condensing greenhouse gases) that control the greenhouse warming of the climate system; (2) water vapor and clouds are feedback effects that magnify the strength of the greenhouse effect due to the non-condensing greenhouse gases by about a factor of three; (3) the large heat capacity of the ocean and the rate of heat transport into the ocean sets the time scale for the climate system to approach energy balance equilibrium.

There are also other natural «modes of variability» which may be affected by a climate change, for instance if the heat transport in the oceans are to change (e.g. the Atlantic meridional overturning circulation AMOC).

We find that the energy transport associated with wind - driven ocean gyres is closely coupled to the energy transport of the midlatitude atmosphere so that, for example, the heat transport of both systems scales in approximately the same way with the meridional temperature gradient in midlatitudes.
