The hydrologic link between land use changes and climate
January 28, 2010 | A new study led by NCAR scientist Peter Lawrence has found that impacts to Earth's hydrological cycle—not changes in the reflection or absorption of solar radiation—are the most important driving force in how human-caused land use changes affect climate. The findings contradict previous research and suggest that land cleared of forest for agriculture could have a greater...

New insight on the atmosphere’s tiniest particles
January 14, 2010 | Many of the smallest particles in the atmosphere emerge through a different process than previously thought, according to analysis from a team led by NCAR's Jim Smith. The team has found that aminium salts make up as much as half of the mass of newly formed particles in places as diverse as Atlanta, Mexico City, northeast Colorado, and Finland. Its work appeared online on 7...
