Lyon thinks this change in temperatures has altered atmospheric circulation patterns, cutting off the supply of moisture to east Africa (Geophysical Research Letters, DOI: 10.1029 / 2011GL050337).

He believes that no one has thought of combining the two theories before because it's not an intuitive idea to look at how the effects of changing patterns of ocean circulation, which occur on time scales of thousands of years, would effect global silicate weathering, which in turn controls global climate on time scales of 100s of thousands of years.

By analyzing these records, Knudson and Ravelo found that the strength of the overturning circulation in the North Pacific is inherently linked to global climate changes, but not in the way scientists had previously thought.

Your statement that «Thus it is natural to look at the real world and see whether there is evidence that it behaves in the same way (and it appears to, since model hindcasts of past changes match observations very well)» seems to indicate that you think there will be no changes in ocean circulation or land use trends, nor any subsequent changes in cloud responses thereto or other atmospheric circulation.

A number of recent studies linking changes in the North Atlantic ocean circulation to sea ice extent led Yeager to think that it would also be possible to make decadal predictions for Arctic winter sea ice cover using the NCAR - based Community Earth System Model...

The Past and Future Ocean Circulation from a Contemporary Perspective, in AGU Monograph, 173, A. Schmittner, J. Chiang and S. Hemming, Eds., 53 - 74, (pdf)» Wunsch's publications page is great food - for - thought, I particularly enjoyed his papers on Ice Age changes and the Milankovitch cycles.

It's thought that there is an improvement in the circulation of this fluid when the lymphatic valves are opened throughout a change in gravitational pull.

I'm still inclined to think that subtle changes in ocean circulation patterns, with resulting local effects on climate, are more likley to be responsible.

Your statement that «Thus it is natural to look at the real world and see whether there is evidence that it behaves in the same way (and it appears to, since model hindcasts of past changes match observations very well)» seems to indicate that you think there will be no changes in ocean circulation or land use trends, nor any subsequent changes in cloud responses thereto or other atmospheric circulation.

It also provides the background state against which El Niño events take place, and so changes in the Walker circulation should form an intrinsic part of thinking about how global warming will affect El Niño.

However, the Trade Winds are primarily caused by the Hadley circulation, and are only modulated by the Walker circulation, so it is more precise to think of this result as indicating a change in strength of the Walker circulation.

Since it spoke of circulation changes and specifically referenced section 3.6.4, I too would have thought they were in fact referring to NAO / NAM (maybe related to NAM accounting for half the warming over Eurasia 1968 — 97?).

This rise of temperature could honcvcr he explained, qualitatively if not quantitatively, by changes in the atiiiospheric circulation, arid in those regions where a change in the circulation aould be expected to cause a fall of temperature, there had actually been a fall; moreover the rise of temperature \ vas about ten times as great in the arctic regions as in middle or low latitudes, and he cliil not think that a change in the amount of carbon dioxide could cause such a differential effect.

This polar amplification is thought to be due largely to changes in sea ice, with some contributions from changes in snow cover, atmospheric and ocean circulation, cloud cover and the presence of soot.

Slow variations in upper ocean heat content that have been observed in the subpolar and marginal ice zone regions of the Atlantic since the mid-twentieth century are thought to be related to changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.

Changes in ocean circulation are thought to be able to produce large rapid temperature cChanges in ocean circulation are thought to be able to produce large rapid temperature changeschanges.

While on first thought this might seem undesirable because we are looking for a global number, it might make sense to separate them due to the large difference in land / ocean ratio and the fact that atmospheric circulation patterns isolate them WRT shorter term changes.

What did they think 60 years ago about the rate of deep ocean circulation, was anything said about what they thought on temperature changes in the abyss?

I think it is really important to make that distinction - that there are a number of factors that influence the extent of Arctic sea ice, some of them of course associated with changes in the radiative forcing from the atmosphere, as a result of anthropogenic greenhouse gases and aerosols, but also changes in the atmospheric circulation and also the advection of heat into or out of the Arctic by the ocean circulation.

I haven't looked at this in detail, but thinking about it in response to your question (changing my story a bit), I am not sure that you need any change in evaporation to get this result — the moisture convergence due to the circulation generated by the localized convection is probably enough.
