The Argon Geochronology for the Earth Sciences (AGES) lab is located at Columbia's Lamont-Doherty Earth Observatory along the Palisades Parkway in Rockland County, New York. Our lab measures Argon isotope compositions and concentrations, mainly of single mineral grains, on a VG5400 noble gas mass spectrometer to determine the age of mineral formation. Our research subjects include paleocllmate provenance studies, volcanoes and deep earth time.
In much of France and Switzerland, the best wine years are traditionally those with abundant spring rains followed by an exceptionally hot summer and late-season drought. This drives vines to put forth robust, fast-maturing fruit, and brings an early harvest. Now, a new study shows that warming climate has largely removed the drought factor from the centuries-old early-harvest equation. It is only the latest symptom that global warming is affecting biological systems and agriculture.
