This synthesis paper summarizes published proxy climate evidence showing the spatial and
temporal pattern of climate change through the Holocene in Arctic Canada and Greenland …

The conterminous United States contains an extensive and generally well-studied record of
Last Glacial loess. The loess occurs in diverse physiographic provinces, and under a wide …

The initial colonization of the Americas remains a highly debated topic, and the exact timing
of the first arrivals is unknown. The earliest archaeological record of Mexico—which holds a …

The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

To predict the future contributions of the Antarctic ice sheets to sea-level rise, numerical
models use reconstructions of past ice-sheet retreat after the Last Glacial Maximum to tune …

Sedimentological data and hydrogen isotopic measurements of leaf wax long-chain n-
alkanes (δD wax) from an alpine lake sediment archive on the southeastern Tibetan Plateau …

High-quality data from appropriate archives are needed for the continuing improvement of
radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating …

Down-core paleolimnological investigations of lake-sediment sequences require sufficient
age control to enable comparisons and correlations on local, regional and global scales …

A lake sediment core from the eastern Tibetan Plateau was investigated by multi-proxy
geochemical, sedimentological and magnetic analyses and its age determined using 14C …

Loess is one of the most widespread subaerial deposits in Alaska and adjacent Yukon
Territory and may have a history that goes back 3 Ma. Based on mineralogy and major and …
