2020 Closes Hottest Decade on Record – UN Weather Agency

Geneva- As 2020 draws to a close, it leaves in its wake the warmest decade on record and one of the three hottest years ever measured, the World Meteorological Organization (WMO) warned on Thursday.

Despite a cooling La Niña event, 2020 has been a year of exceptional heat that is now mature and impacting weather patterns in many parts of the world, the UN Agency said.

According to most models, La Niña is expected to peak in intensity either this month or in January and continue through the early part of next year.

“Record warm years have usually coincided with a strong El Niño event, as was the case in 2016”, said WMO chief Petteri Taalas.

“Despite the current La Niña conditions, this year has already shown near-record heat comparable to the previous record of 2016,” he added.

In January, the UN agency will issue consolidated temperature figures for 2020, based on five global temperature datasets.

This will be incorporated into a final report on the State of the Climate in 2020, which will be issued in March and will include information on selected climate impacts.

To date, all five datasets for the first 10 months of 2020 has placed this year as the second warmest for the year to date, following 2016 and ahead of 2019.

Based on monthly reports from the European Union’s Copernicus Climate Change Service, the United States National Oceanic and Atmospheric Administration and NASA’s Goddard Institute for Space Studies and the Japan Meteorological Agency, November has been classified as either the warmest or second warmest on record.

The difference between the warmest three years is small and exact rankings for each data set could change once data for the entire year are available, according to WMO.
