WMO confirms 2016 as hottest year on record

Weather - Senegal

The year 2016 has been confirmed as the hottest year on record, surpassing the exceptionally high temperatures of 2015, according to a consolidated analysis by the World Meteorological Organization (WMO).

The globally averaged temperature in 2016 was about 1.1°C higher than the pre-industrial period. It was approximately 0.83° Celsius above the long term average (14°C) of the WMO 1961-1990 reference period, and about 0.07°C warmer than the previous record set in 2015. 

“2016 was an extreme year for the global climate and stands out as the hottest year on record,” said WMO Secretary-General Petteri Taalas. “But temperatures only tell part of the story.”

“Long-term indicators of human-caused climate change reached new heights in 2016,” he said. « Carbon dioxide and methane concentrations surged to new records. Both contribute to climate change,” said Mr Taalas.  

Carbon dioxide remains in the atmosphere for centuries and in the ocean, where it acidifies the water, for even longer. It is now above the symbolic and significant level of 400 parts per million concentration in the atmosphere.

“We have also broken sea ice minimum records in the Arctic and Antarctic,” said Mr Taalas. “Greenland glacier melt – one of the contributors to sea level rise _ started early and fast. Arctic sea ice was the lowest on record both at the start of the melt season in March and at the height of the normal refreezing period in October and November, » he said.

“The Arctic is warming twice as fast a the global average. The persistent loss of sea ice is driving weather, climate and ocean circulation patterns in other parts of the world. We also have to pay attention to the potential release of methane from melting permafrost,” said Mr Taalas.

A very powerful warming El Niño event fuelled high temperatures in the early months of 2016. But even after the end of El Niño, temperatures remained well above average.

All the 16 hottest years on record have been this century, apart from 1998 when there was a strong El Niño.
