Climate change plateau is likely temporary but hard to explain

New York Times : Surface temperatures have risen slower in the past 15 years than in the previous 20, but that hasn’t changed the longer-term warming trend. Why warming has slowed in the short term isn’t known, but several theories have been proposed, and they may all contribute. One theory is that much of the heat trapped by greenhouse gases is being absorbed by the deep oceans, possibly due to shifts in winds and currents. Another points to a similar slowdown between the 1950s and 1970s. That period of slower warming may have been caused by an increase in atmospheric pollution that reflected sunlight. And in the past few decades, China and other developing countries have massively increased air pollution. Despite the slowdown, and whatever its cause, most of the hottest years on record have occurred during this recent period of slower warming.
