At the U.N. climate change meeting in Marrakech today, the World Meteorological Organization released its preliminary analysis of recent global temperature trends. In its press release the WMO reported:
It is very likely that 2016 will be the hottest year on record, with global temperatures even higher than the record-breaking temperatures in 2015. Preliminary data shows that 2016's global temperatures are approximately 1.2° Celsius above pre-industrial levels, according to an assessment by the World Meteorological Organization (WMO).
Global temperatures for January to September 2016 have been about 0.88° Celsius (1.58°F) above the average (14°C) for the 1961-1990 reference period, which is used by WMO as a baseline. Temperatures spiked in the early months of the year because of the powerful El Niño event of 2015-16. Preliminary data for October indicate that they are at a sufficiently high level for 2016 to remain on track for the title of hottest year on record. This would mean that 16 of the 17 hottest years on record have been this century (1998 was the other one).
"Another year. Another record. The high temperatures we saw in 2015 are set to be beaten in 2016," said WMO Secretary-General Petteri Taalas. The extra heat from the powerful El Niño event has disappeared. The heat from global warming will continue," he said.
The folks at University of Alabama at Huntsville who curate the satellite global temperature data also reported earlier that 2016 may edge out 1998 as the hottest year in its record.
