A fundamental element of today's climate system is a conveyor -
like ocean circulation pattern that distributes vast quantities of heat and moisture around our planet.

This variability includes the Pacific Decadal Oscillation (PDO), a long - lived El Niño -
like pattern of Pacific climate variability that works
like a switch every 30 years or so between two different
circulation patterns in the North Pacific
Ocean.
The deepening of the Drake Passage resulted in a change in
ocean circulation that resulted in warm waters being directed northwards in
circulation patterns like those found in the Gulf Stream that currently warms northwestern Europe.
Alley is talking mainly about D / O events and,
like some others (Broecker for instance) tried to link it to the LIA, but neither the
pattern of change, the abruptness, the
ocean circulation change nor the magnitude actually match.
Now that we know much more than we did about
ocean circulation patterns, intermixing and the
like (although there is still much to learn) we need to get this message across in much simpler fashion than we have done so far.
Expecting less than 5 % of Earths surface to filter the air mass from the other 95 % given actual air
circulation patterns is patently absurd compared to natural CO2 scrubbing mechanisms
like the biological carbon cycles, or Henry's law (which is leading to
ocean acidification.
That is because there are factors,
like air and
ocean circulation patterns, that affect both the rate and the intensity of the global warming.
The models (and there are many) have numerous common behaviours — they all cool following a big volcanic eruption,
like that at Mount Pinatubo in 1991; they all warm as levels of greenhouse gases are increased; they show the same relationships connecting water vapour and temperature that we see in observations; and they can quantify how the giant lakes left over from the Ice Age may have caused a rapid cooling across the North Atlantic as they drained and changed
ocean circulation patterns.
