As global warming affects the earth and ocean, the retreat of the sea ice means there won't be as much cold, dense water, generated through a process known
as oceanic convection, created to flow south and feed the Gulf Stream.

Three basic forces are believed to drive
oceanic plate movement: plates are «pushed» away from mid-ocean ridges
as new sea floor forms; plates are «pulled»
as the oldest parts of the plate dive back into the earth at subduction zones; and
convection within the asthenosphere helps ferry the plates along.
The mechanism by which the effect of
oceanic variability over time is transferred to the atmosphere involves evaporation, conduction,
convection, clouds and rainfall the significance of which has to date been almost entirely ignored due to the absence of the necessary data especially
as regards the effect of cloudiness changes on global albedo and thus the amount of solar energy able to enter the oceans.
The IPCC summary is deeply flawed
as a scientific document and
as I have explained in other recent articles it appears impossible for increased levels of atmospheric CO2 at the puny levels caused by mankind to affect the characteristics of the atmosphere enough to significantly enhance the greenhouse effect and even if it could do so then any such effect would be quickly neutralised by the primary solar /
oceanic driver and the oceans acting in conjunction with evaporation, condensation and atmospheric
convection (which includes clouds and rain).
