The U.N. weather agency has issued a “red alert” about the climate emergency as new data from the World Meteorological Organization shows 2023 was by far the warmest year on record and that this year may be even hotter. Celeste Saulo, the secretary-general of the WMO, spoke on Tuesday.

Celeste Saulo: “The year 2023 set new records for every single climate indicator. This annual report shows that the climate crisis is the defining challenge that humanity faces. It is closely intertwined with the inequality crisis, as witnessed by growing food insecurity, population displacement and biodiversity loss.”
