With the removal of the warm surface waters, an upwelling current is created in the east Pacific Ocean, bringing cold water up from deeper levels.

The winds in turn drive the ocean currents that keep the cold water in the east and the water warm in the west.

Current state - of - the - art climate models predict that increasing water vapor concentrations in warmer air will amplify the greenhouse effect created by anthropogenic greenhouse gases while maintaining nearly constant relative humidity.

Since deeper waters will be warmer, there is a possible link to the global ocean circulating currents that results in warmer water in polar regions.

This could be do to changes in ocean circulation, and warming waters reaching the grounding lines for ice shelves in Arctic and Antarctica, leading to non-linear increase in melting and sea level rise, impossible to avoid on our current path.

This isn't news to top climate scientists around the world (see Hadley Center: «Catastrophic» 5 — 7 °C warming by 2100 on current emissions path) or even to top climate scientists in this country (see US Geological Survey stunner: Sea - level rise in 2100 will likely «substantially exceed» IPCC projections, SW faces «permanent drying») and certainly not to people who follow the scientific literature, like Climate Progress readers (see Study: Water - vapor feedback is «strong and positive,» so we face «warming of several degrees Celsius»).

Hurricane season may be enhancing the current problem, resulting in low water circulation in the southwestern Caribbean and thus creating a «warm pocket» of water along the coasts of Panama and Costa Rica, the researchers speculate.

I'm a fish geneticist so I won't bother commenting on «paleo - ocean current - ology», but it seems to me that glaciation would result in a reduction of fresh water inputs to the North Atlantic (during the ice age) and would therefore be quite different from the mechanism in question (which is related to early phases of global warming).

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

A lot of reseach energy is being devoted to the study of Methane Clathrates — a huge source of greenhouse gases which could be released from the ocean if the thermocline (the buoyant stable layer of warm water which overlies the near - freezing deep ocean) dropped in depth considerably (due to GHG warming), or especially if the deep ocean waters were warmed by very, very extreme changes from the current climate, such that deep water temperatures no longer hovered within 4C of freezing, but warmed to something like 18C.
