According to the 35th annual State of the Climate report, greenhouse gas concentrations, the global temperature across land and oceans, global sea level, and ocean heat content all reached record highs in 2024, and glaciers lost the most ice of any year on record.

The international review of the world’s climate, published by the Bulletin of the American Meteorological Society (BAMS), is based this year on contributions from 589 scientists in 58 countries. For decades, the State of the Climate has provided the most comprehensive annual update on Earth’s climate⁠ — illuminating not only key indicators like global CO2 but also notable weather events, regional phenomena, and other data collected by environmental monitoring stations and instruments located on land, water, and ice, as well as in space.

“The State of the Climate report is an annual scientific landmark,” says American Meteorological Society President David J. Stensrud. “It is a truly global effort, in which hundreds of researchers from universities, government agencies, and more come together to provide a careful, rigorously peer-reviewed report on our planet’s climate. High-quality observations and findings from all over the world are incorporated, underscoring the vital importance of observations to monitor, and climate science to understand, our environment. The results affirm the reality of our changing climate, with 2024 global temperatures reaching record highs."
