2014 Was The Hottest Year On Record Globally By Far
As the JMA graph shows, there has been no “hiatus” or “pause” in warming. In fact, there has not even been a slowdown. Yes, in JMA’s ranking of hottest years, 1998 is in (a distant) second place — but 1998 was an outlier as the graph shows. In fact, 1998 was boosted above the trendline by an unusual super-El Niño. It is usually the combination of the underlying long-term warming trend and the regional El Niño warming pattern that leads to new global temperature records.
What makes setting the record for hottest year in 2014 doubly impressive is that it occurred despite the fact we're still waiting for the start of El Niño.
