In this study we report changes in Indian summer monsoon (ISM) intensity during the past~
3500 yr inferred from proxy indices at Lake Erhai, southwestern China. Both the pollen …

Despite the longstanding significance of North America's Great Lakes, little is known about
their preindustrial ecology. Here, we report on when and how humans first became a main …

A synthesis of 93 hydrologic records from across North and Central America, and adjacent
