The result is that most moderate to strong El Nino years are record hot years, pushing the global temperature average ever higher through a cycle of natural variability warped toward hot by human greenhouse gas forcing. And, in fact, even two of the recent weak El Nina years, 2005 and 2010, were both hottest years on record:
