The Antarctic Circumpolar Current (ACC) since the Last Interglacial is reconstructed, showing orbital-scale shifts in ACC position driven by eccentricity and precession, possibly counteracting the predicted southward shift due to global warming.

Lead (Pb) isotopes from a ferromanganese crust reveal that during lukewarm interglacials before the Mid-Brunhes Event, stronger deep Southern Ocean stratification limited CO2 release, helping keep atmospheric CO2 levels lower.

Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

The projected loss of glaciers in California’s Sierra Nevada is likely unprecedented in at least the past 30,000 years.

Abstract. The ocean takes up over 90 % of the excess heat stored in the Earth system as a result of anthropogenic climate change, which has led to sea level rise and an intensification of marine extre...

Ocean stratification — density-related layering of seawater — influences oceanographic and climatic processes. This Review outlines observed and projected changes in stratification, noting a 0.8% dec−1 increase in 0–2,000 m stratification from 1960–2024, and a further 1.4% dec−1 increase by 2100 under SSP2-4.5.

Abstract. The magnitude, source, release location, and timing of freshwater that ends up in the numerous Greenland fjords is of special interest for ice–ocean interactions and ecosystems. In this stud...

Characterizing weather extremes from the past to add context to future impacts

Atmospheric rivers are dynamically coupled to orbit through latitudinal shifts in wind belts and seasonal shifts in moisture availability High latitude moisture controls the frequency, intensity,...

The annual award ceremony features miniature operas, scientific demos, and the 24/7 lectures.

A better-ventilated North Pacific could have reduced the carbon of water upwelled in the Southern Ocean, reducing outgassing and revealing a remote influence on Southern Ocean biogeochemistry in glaci...
