It’s Official:  2017 Was the Second Hottest Year on Record

Last year was the second hottest year on record worldwide, behind 2016, according to a European Union climate monitoring program.  Global temperatures averaged 14.7 degrees Celsius (58.46°F) — 1.2 degrees C (2.2°F) above pre-industrial times.

The announcement comes from the Copernicus Climate Change Service (C3S), a research project by the European Union to provide past and current climate data to help inform EU climate policies.  It is the first major weather or climate agency to report 2017’s final average temperatures, but the measurements back up a projection by the World Meteorological Organization (WMO) made in November that 2017 would be the second- or third-hottest year on record, according to Reuters.

C3S reported that last year was just 0.1 degrees C cooler than 2016, and 0.5 degrees C warmer than the 1981-2010 period.

While 2016’s temperatures were boosted by an intense El Niño event in the Pacific Ocean, C3S said that 2017 saw very little influence from that event.  Rather, “2017 was close to the warmest year on record despite cooling La Niña conditions both early and late in the year,” the report said.
