WMO global mean temperature for 2023
Climate & environment · Temperatura global · Observación climática · Indicadores climáticos
WMO reported that the global mean near-surface temperature in 2023 was 1.45 °C ± 0.12 °C above the 1850–1900 average, its pre-industrial reference, and was the warmest year in the observational record at that time. The figure is a consolidated annual global estimate; it does not by itself describe every region’s temperature or the long-term warming used to assess the Paris goals.
