This data image shows the monthly average sea surface temperature for May 2015. Between 2013 and 2016, a large mass of unusually warm ocean water – nicknamed the Blob – dominated the North Pacific, indicated here by red, pink, and yellow colors signifying temperatures as much as three degrees Celsius […]

An artist’s rendering of undersea earthquake waves. Credit: Caltech Using soundwaves cast from seafloor earthquakes, researchers demonstrate a new take on a largely abandoned way to measure ocean warming worldwide — seismic ocean thermometry. The method, which they tested in the East Indian Ocean and where they uncovered a decadal […]

The prevailing theory has been that sea ice can act as a lid to keep carbon in the ocean from escaping back to the atmosphere. However, researchers at MIT have now identified a counteracting effect that suggests Antarctic sea ice may not be as powerful a control on the global […]

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. […]
