The CENOGRID shows Earth has experienced four distinct climate states over the last 66 million years. The detailed climatic changes of the past can be studied like a colorful barcode and provide context for ongoing anthropogenic change and how exceptional it is. Earth’s climate has gradually cooled for the last […]

With a launch planned in 2027, the Copernicus Polar Ice and Snow Topography Altimeter, CRISTAL, mission will carry, for the first time, a dual-frequency radar altimeter, and microwave radiometer, that will measure and monitor sea-ice thickness, overlying snow depth, and ice-sheet elevations.

Sea ice can act as an agent of climate change on a variety of timescales and spatial scales—it’s not just a passive responder to change. The Little Ice Age may have arisen “out of the blue,” from internal variability within the climate system, rather than in response to an external […]

This map overlays the probability of burn severity in California’s northern coastal mountains, as forecasted in a UC Davis study, with burn perimeters of wildfires burning in September 2020.

A blazing sunset lights up the evening sky. Credit: NOAA Four years of research confidently narrows range of 1.5°C-4.5°C down to 2.3°C-3.9°C. The most advanced and comprehensive analysis of climate sensitivity yet undertaken has revealed with more confidence than ever before how sensitive the Earth’s climate is to carbon dioxide. […]
