The higher sea surface temperatures in the tropics (~ 0.85 K / decade in recent decades) have lead to an increase in LW (infrared) radiation, and a loss to space of some 3 W / m2 all over the tropics (50 % of the surface), which more than halves the — theoretical — global influence (~ 2.4 W / m2) of all extra GHGs together since the start of the industrial revolution.

Updated, 3:10 p.m. Using climate models and observations, a fascinating study in this week's issue of Nature Climate Change points to a marked recent warming of the Atlantic Ocean as a powerful shaper of a host of notable changes in climate and ocean patterns in the last couple of decades — including Pacific wind, sea level and ocean patterns, the decade - plus hiatus in global warming and even California's deepening drought.

Variability in the prevailing winds (which can extend over decades, England et al. 2014) will therefore lead to variability in the water level along the coasts — but of course we know that the wind can not change global sea level at all as it merely redistributes the water.
