WMO Report: State of the Global Climate 2023

The World Meteorological Organization (WMO) “State of the Global Climate 2023” report confirms that last year broke every single climate indicator to be, by far, the warmest year on record.

Mountains and glaciers

Released on 19 March 2024, “State of the Global Climate 2023” finds that, in 2023, concentrations of greenhouse gases continued to rise; ocean heat content and sea level reached record observed highs; and, the rate of increase is accelerating. Antarctic sea ice extent hit record observed lows, and key glaciers suffered record losses.  

WMO Secretary-General, Prof. Celeste Saulo, said, “Never have we been so close – albeit on a temporary basis – to the 1.5° C lower limit of the Paris Agreement on climate change. Heatwaves, floods, droughts, wildfires and intense tropical cyclones wreaked havoc on every continent and caused huge socio-economic losses. There were particularly devastating consequences for vulnerable populations who suffer disproportionate impacts.

“Extreme climate conditions exacerbated humanitarian crises, with millions experiencing acute food insecurity and hundreds of thousands displaced from their homes. WMO is committed to stepping up collaboration with the international community to confront the enormity of this challenge.”
