As manmade, carbon emissions-driven climate change forces temperatures up, research shows that nature is pushing back:  Naturally-occurring variations in ocean currents are expected to counteract the global warming trend over the next decade.

Scientists at the Leibniz Institute for Marine Science in Germany studied a current know as the meridional overturning current (MOC), which cycles water through the North Alantic and returns colder water southward.  A strong MOC results in warmer water and milder northern climates, while a weaker current does the opposite. 

Because the strength of the MOC fluctuates on a natural, 70- to 80-year cycle, and we're poised to enter a weak period, temperatures in the North Atlantic should cool over the next 10 years or so.  Temps in the tropical Pacific will likely remain the same.
