This work highlights a sharp warming contrast within the Southern Ocean: the Atlantic-Indian sector warms faster than the Pacific due to wind-driven heat transport. The contrast is projected to persis...

I am delighted to have been chosen as a lecturer in the American Geophysical Union Distinguished Lecture Series for 2025-2026. Would you like to hear about “Caves and their stalagmites: linki…

Abstract. Carbonate U–Pb dating has become a key tool for Quaternary palaeoclimatology and palaeoanthropology beyond the age limit of Th–U disequilibrium dating. U–Pb geochronology is based on the pai...

Reconstructed radiocarbon ventilation seesaw and reduced Southern Ocean surface reservoir age imply reduced Antarctic Bottom Water overturning parallel to the weakened North Atlantic Deep Water overturning during the early deglaciation.

Early Pleistocene artefacts at Calio suggest that Sulawesi was populated by hominins at around the same time as Flores, if not earlier.

Boron isotopes are an important marine paleoclimate proxy to reconstruct past ocean pH and atmospheric carbon dioxide in geological time Sources of uncertainty of past CO2 estimation shifts from ...

Forests across the southwestern U. S. face escalating challenges from changing climate. The objective of this study, conducted in partnership with the…

Uranium-series analyses provide dates for 15 annually banded coral skeletons on the low Caribbean island of Anegada A subset of the corals was likely washed ashore in a Puerto Rico Trench tsunami...

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.

Clams reveal North Atlantic destabilization in the early 20th century and at present.

Scientific Reports - Intensification of marine heatwaves and their climate drivers in the Arabian Gulf

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 ...

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.
