Hottest September on record puts 2023 on track to be warmest year ever

This September was the hottest one ever and 2023 is firmly set to be the warmest year on record, the World Meteorological Organization (WMO) said on Thursday, citing data from the European Union’s Copernicus Climate Change Service (C3S). 

Last month was the hottest June since records began and the thirteenth month in a row to set a temperature record, according to new data released on Monday from the European Union’s Copernicus Climate Change Service.

In the wake of data released by the United Nations World Meteorological Organization (WMO), showing the past four years were officially the ‘four warmest on record,’ UN Secretary-General António Guterres called for urgent climate action and increased ambition, ahead of his climate summit in September.
