2020 closes the warmest decade on record according to the World Meteorological Organization (WMO) in its Global Annual to Decadal Climate Update. Despite the cooling of La Ninã event, 2020 is still considered to be the warmest, impacting, hence, the meteorological conditions of many regions in the world. 

La Ninã, which can be defined as a cooling of the water in the equatorial Pacific that occurs at irregular intervals and is associated with widespread changes in weather patterns complementary to those of El Niño, is expected to reach its peak this month. Despite its cooling effects, according to the WMO Secretary-General Prof. Taalas, La Ninã will not be enough to put an end to this year’s heat. 

He adds that “record warm years have usually coincided with a strong El Niño event, as was the case in 2016” and that there is at least a one in five chance of it temporarily exceeding 1.5 °C by 2024. 

During this month, WMO will publish databases of the temperatures of 2020 based on five global databases which will be included in a final report on the state of the climate in 2020 and will be published in March 2021.
