State of the global climate 2023

The publication provides a summary on the state of the climate indicators in 2023 with sections on key climate indicators, extreme events and impacts. The indicators include global temperatures, greenhouse gas concentration, ocean heat content, sea level rise, ocean acidification, Arctic and Antarctic sea ice, Greenland ice sheet and glaciers and snow cover, precipitation and stratospheric ozone, with an analysis of major drivers of inter-annual climate variability during the year including the El Niño Southern Oscillation and other ocean and atmospheric indices.

The State of the Global Climate 2023 report shows that records were once again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat. The publication also provides most recent finding on climate related risks and impacts including on food security and population displacement.
