“2014 Was The Hottest Year On Record Globally By Far”
The Japan Meteorological Agency (JMA) has announced that 2014 was the hottest year in more than 120 years of record-keeping — by far. NOAA is expected to make a similar call in a couple of weeks and so is NASA.
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. But this is what happens when a species keeps spewing record amounts of heat-trapping carbon pollution into the air, driving CO2 to levels in the air not seen for millions of years, when the planet was far hotter and sea levels tens of feet higher.
The JMA is a World Meteorological Organization (WMO) Regional Climate Center of excellence. The WMO had announced a month ago that 2014 was on track to be hottest year on record. Different climate-tracking groups around the world use different data sets, so they can show different results for 2014 depending on how warm December turns out to be.
