Columbia Engineers find strong feedbacks between the atmosphere and vegetation that explain up to 30% of precipitation and surface radiation variance; study reveals large potential for improving seasonal weather predictions.

New research led by scientists at Lamont-Doherty Earth Observatory shows that the health and environmental benefits of U.S. clean air policies extend to global climate.

Scientists from Lamont-Dohery Earth Observatory have discovered that seasonally flowing streams fringe much of Antarctica’s ice. The widespread presence of these melt streams signals that the ice may be more vulnerable to melting than previously thought.

A new Indonesian coral-based record of surface ocean salinity shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere influences a major current in the far western Pacific Ocean.

Scientists studying Inner Mongolia's Lake Dali have concluded that the size of the lake has changed dramatically over the distant past, due to changes in the climate and resulting shifts in the annual monsoon.
