Lamont’s Linda Heusser turned 90 years old on April 12, and the only birthday present she really wanted was another sediment core to study.

A new study bolsters the idea that the uplifts of the Himalayas and Andes that began tens of millions years ago helped trigger the many ice ages that followed.

Gases collected from ancient groundwater provide a compelling portrait of how much past temperatures have swung back and forth.

Using radar and other techniques, researchers have mapped out the sediments left by a lake that apparently existed before Greenland was glaciated. Next step: drilling through the ice to see what they contain.

An international team suggests that research centers around the world using numerical models to predict future climate change should include simulations of past climates.

A simple fascination with winter and weather patterns led D’Arrigo to become a globe-trotting scientist who collects and analyzes important data from tree rings.

Kevin Uno, a Center for Climate and Life Fellow, studies how abrupt changes in climate affected Neolithic human settlement, diet, and abandonment in northwest Africa.

Recovering ancient seafloor sediments requires complicated machinery and a skilled crew.

Joerg Schaefer and Gisela Winckler, scientists at Lamont-Doherty Earth Observatory, received funding from the Center for Climate and Life to examine the vulnerability of Greenland’s massive ice sheet.
