Format
As 2020 draws to an end, it closes the warmest decade (2011-2020) on record, according to the World Meteorological Organization. This year remains on track to be one of the three warmest on record, and may even rival 2016 as the warmest on record. The six warmest years have all been since 2015.
The exceptional heat of 2020 is despite a cooling La Niña event, which is now mature and impacting weather patterns in many parts of the world. According to most models, La Niña is expected to peak in intensity in either December or January and continue through the early part of 2021, according to a new WMO summary.
