While winter sea ice extent in the Southern Ocean as a whole has changed little, the sea ice here begins to advance about 2 months later than it did in the 1980s and retreat about a month earlier. (ldeo.columbia.edu)
As discussed above, it is plausible that the stability of the Atlantic atmosphere relative to the tropical mean is sensitive to warming of the Atlantic SSTs relative to the warming of the tropical oceans as a whole. (gfdl.noaa.gov)
... then why do the vertical mean temperature anomalies (NODC 0 - 2000 meter data) of the Pacific Ocean as a whole and of the North Atlantic fail to show any warming over the past decade, a period when ARGO floats have measured subsurface temperatures, providing reasonably complete coverage of the global oceans?
