Washington, D.C.— Over the past two decades, extensive forest death triggered by hot and dry climatic conditions has been documented on every continent except Antarctica. Forest mortality due to...
Washington, D.C.— There is enough energy available in winds to meet all of the world’s demand. Airbourne wind turbines that convert steadier and faster high-altitude winds into energy could generate...
Washington, D.C. – For years, scientists have debated how big a role elephants play in toppling trees in South African savannas. Tree loss is a natural process, but it is increasing in some regions,...
Washington, D.C.—Using new, highly efficient techniques, Carnegie and Colombian scientists have developed accurate high-resolution maps of the carbon stocks locked in tropical vegetation for 40% of...
Washington, D.C.— When evaluating the historic contributions made by different countries to the greenhouse gasses found in Earth’s atmosphere, calculations generally go back no further than the year...
Washington, D.C. — One idea for fighting global warming is to increase the amount of aerosols in the atmosphere, scattering incoming solar energy away from the Earth’s surface. But scientists...
Washington, D.C.—Carnegie staff scientist Greg Asner has been selected as one of 22 experts to serve the U.S. government as part of the Energy and Climate Partnership of the Americas (ECPA) through...

Coral reefs are havens for marine biodiversity and underpin the economies of many coastal communities. But they are very sensitive to changes in ocean chemistry resulting from greenhouse gas emissions, as well as to pollution, warming waters, overdevelopment, and overfishing. Reefs use a mineral...
Chris Field is a co-principal investigator of the Jasper Ridge Global Change Experiment at the Jasper Ridge Biological Preserve in northern California. The site, designed to exploit grasslands as models for understanding how ecosystems may respond to climate change, hosts a number of studies of the...
Monitoring tropical deforestation and forest degradation with satellites can be an everyday activity for non-experts who support environmental conservation, forest management, and resource policy development.
Through extensive observation of user needs, the Greg Asner team developed CLASlite ( the...
Anna Michalak joined Carnegie in 2011 from the Department of Civil and Environmental Engineering at the University of Michigan. Her research focuses on characterizing complexity and quantifying uncertainty in environmental systems to improve our understanding of these systems and our ability to...
Ken Caldeira has been a Carnegie investigator since 2005 and is world renowned for his modeling and other work on the global carbon cycle; marine biogeochemistry and chemical oceanography, including ocean acidification and the atmosphere/ocean carbon cycle; land-cover and climate change; the long-...
Joe Berry has been a Carnegie investigator since 1972. He has developed powerful tools to measure local and regional exchanges of carbon over spaces of up to thousands of square miles. He uses information at the plant scale to extrapolate the carbon balance at regional and continental scales....
