Park Williams studies trees and climate, in particular the causes of drought and the effects of climate change on forests. In this latest in a series of Earth Institute videos, we spoke to him about what he does, what’s important about it, and how his interest in history and environmental science blended into a career.
Yael Kiro, an associate research scientist at Lamont-Doherty Earth Observatory, has received the 2017 Professor Rafi Freund Award from the Israel Geological Society for work published on the ancient climate history of the Dead Sea.
The vast majority of scientists around the world agree that our climate is changing at a faster rate than ever recorded in human history because of our use of fuels such as coal and oil, so-called fossil fuels. The conclusion rests on basic physics known since the early 1800s, when physical scientists first recognized that carbon dioxide, then a recently discovered gas, could act as a sort of greenhouse, preventing heat introduced by the sun from escaping back into space – the “greenhouse effect.”
A new study shows that dryness of the atmosphere affects U.S. grassland productivity more than rainfall does. The findings could have important implications for predicting how plants will respond to warming climate conditions.
The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.
Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.
We’re talking to experts around the Earth Institute about what they’re working on, what they would like people to know about it, and what inspired them to go into their field.
The news doesn’t come as a surprise to scientists and others who’ve been watching, but marks a milestone nonetheless: 2016 was the warmest year on record, dating back to the start of modern record keeping in 1880.
James Hansen, director of the Program on Climate Science, Awareness and Solutions at the Earth Institute and former director of the NASA Goddard Institute for Space Studies, is being honored with the BBVA Foundation Frontiers of Knowledge Award in Climate Change.
An improved technique developed by a graduate student at Lamont-Doherty Earth Observatory and her colleagues is making it possible to use airborne ice-penetrating radar to reveal meltwater’s life under the ice throughout the year.
