Attribution seems to be largely due to changes in surface albedo. One thesis is dust from the Sahara [1], the other (from the QT) appears to be reduced sulfur emissions due to fuel composition changes [2]. Just a shallow reading seems to indicate that this effect might be the opposite -- that the removal of certain particulates has resulted in the ocean absorbing a greater fraction of solar energy rather than reflecting it into the atmosphere. This seems like a net removal of heat from the atmosphere.
