Event stratigraphy is used to help characterise the Anthropocene as a chronostratigraphic
concept, based on analogous deep-time events, for which we provide a novel …

Human activities have already modified the chemical composition of the natural atmosphere
even in very remote regions of the world. The study of chemical parameters stored in solid …

Although long considered to be of marginal importance to global climate change,
tropospheric aerosol contributes substantially to radiative forcing, and anthropogenic sulfate …

This third edition of Reconstructing Quaternary Environments has been completely revised
and updated to provide a new account of the history and scale of environmental changes …

The Greenland Ice Sheet Project 2 glaciochemical series (sodium, potassium, ammonium,
calcium, magnesium, sulfate, nitrate, and chloride) provides a unique view of the chemistry …

Understanding natural causes of climate change is vital to evaluate the relative impacts of
human pollution and land surface modification on climate. We have investigated one of the …

A compilation of paleoclimate records from lake sediments, trees, glaciers, and marine
sediments provides a view of circum-Arctic environmental variability over the last 400 years …

Increases and expansion of anthropogenic emissions of both oxidized nitrogen compounds,
NO x, and a reduced nitrogen compound, NH 3, have driven an increase in nitrogen …

Concern about the potential climatic influence of changing atmospheric aerosol loadings
was first voiced in the 1960s, when Mccormick and Ludwig (1967) suggested that increasing …

Sulfate concentrations from continuous biyearly sampling of the GISP2 Greenland ice core
provide a record of potential climate-forcing volcanism since 7000 BC Although 85 percent …
