A major puzzle of paleoclimatology is why, after a long interval of cooling climate, each late
Quaternary ice age ended with a relatively short warming leg called a termination. We here …

Two fundamental questions about the ice-age climate system await satisfactory resolution.
First, if summer solar radiation intensity truly controls the orbital signature of the last glacial …

The alkenone‐based U proxy is a cornerstone of paleoclimatology, providing insight into the
temperature history of the Earth's surface ocean. Although the relationship between U and …

Changes in the strength and position of Southern Hemisphere westerly winds during the
Last Glacial cycle have been invoked to explain both millennial and glacial–interglacial …

Although detailed age models exist for some marine sediment records of the last glacial
cycle (0–150 ka), age models for many cores rely on the stratigraphic correlation of benthic …

The carbon isotopic composition of individual plant leaf waxes (a proxy for C3 vs. C4
vegetation) in a marine sediment core collected from beneath the plume of Sahara-derived …

During the last deglaciation, warming over Antarctica was interrupted by a return to colder
conditions from about 14,540 to 12,760 yr ago. This period, known as the Antarctic Cold …

Environmental DNA (eDNA) metabarcoding is emerging as a novel, objective tool for
monitoring marine metazoan biodiversity. Zooplankton biodiversity in the vast open ocean is …

Abstract The cold Last Glacial Maximum, around 20,000 years ago, provides a useful test
case for evaluating whether climate models can simulate climate states distinct from the …

Determining whether glaciers registered the classic Last Glacial Maximum (LGM;∼ 26,500–
∼ 19,000 yrs ago) coevally between the hemispheres can help to discriminate among …
