Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

Opposing wet and dry conditions in Central and mainland Southeast Asia over the past millennium were controlled by climate variability over the Pacific and Indian oceans, a pattern likely to become mo...

A South Pacific neodymium isotope time series suggests Antarctic ice sheet growth triggered the mid-Pleistocene transition.

The world faces energy shortages as fossil fuels are phased out. Research can’t go on as normal.

New data detail how tiny forms of life rebounded much more quickly than previously believed

Abstract. Constructing accurate age models for Pleistocene marine sediments is crucial for our understanding of glacial-interglacial cycles and other climatic processes. Benthic foraminiferal δ18O sta...

Oxygen content was lower than modern throughout much of the glacial Atlantic Ocean Changes in preformed δ13C and oxygen were critical components of the observed difference between the last glacia...

During the Last Glacial Maximum, the deep Northwest Atlantic was only about 2 °C colder than today, suggesting sustained production of relatively warm North Atlantic Deep Water during the Last Glacial...

Glaciers in New Zealand retreated at about the same time as mid-latitude glaciers in the Northern Hemisphere during Heinrich Stadials, indicating strong global teleconnections during the last glacial ...

The melting of the last remnants of the North American ice sheets in the early Holocene led to 14 m of global sea-level rise, higher than prior estimates, according to proxy constraints from the Missi...

Simulated collapse of the Atlantic Meridional Overturning Circulation affects atmospheric CO2 ${\text{CO}}_{2}$ and δ13CCO2 ${C}_{\mathit{CO2}}$ Largest effect on ocean δ13CDIC ${C}_{\mathit{DIC}...

New simulations reveal how atmospheric rivers influenced Greenland’s ice sheet during the Last Interglacial—offering clues to future melt in a warming world.

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 ...

Zhou et al. report an abrupt weakening of the Atlantic Meridional Overturning Circulation at the last glacial inception. The observed circulation slowdown could explain the delayed timing of the atmos...

An Atlantic meridional overturning circulation slowdown drives widespread shifts in tropical rainfall through the propagation of high-latitude cooling into the tropical North Atlantic.

Foraminifera-bound nitrogen isotopes trace the early Pliocene restriction of nutrient exchange across the Central American Seaway Geochemical data indicate four phases of seaway shoaling between ...

Dismissed researchers were improving severe weather predictions

Identifying the specific roles of precession, obliquity, and eccentricity in glacial-interglacial transitions is hindered by imprecise age control. We circumvent this problem by focusing on the morpho...

Elizabeth Gray, spent a life in dusty boots, wielding a hammer over rocky bluffs in search of Scotland's Lower Paleozoic fossils.

An ice core suggests that the West Antarctic Ice Sheet lost ice 125,000 years ago, but not to the extent proposed by some scenarios.

Critical Slowing Down (CSD) indicators can raise a false alarm of a nonexistent collapse when applied to an idealized Atlantic meridional overturning circulation (AMOC) model Applying CSD to the ...

An increase in wildfire extent and related greenhouse gas emissions can be linked to abrupt climatic changes during the last glacial period.

Shifts in the world’s largest ocean current are closely linked to Southern Ocean upwelling during warm intervals in Earth’s past.
