Global Ecology Stories
San Francisco, CA —Researchers from the Carnegie Institution are rolling out results from the new Airborne Taxonomic Mapping System, or AToMS, for the first time at the American Geophysical Union (...
Washington, D.C.— Solar radiation management is a type of geoengineering that would manipulate the climate in order to reduce the impact of global warming caused by greenhouse gasses. Ideas include...

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...

In March 2014, a technical support unit (TSU) of ten, headquartered at Global Ecology, had successfully completed a herculean management effort for the 2000-page assessment Climate Change 2014: Impacts, Adaptation, and Vulnerability, including two summaries. They were issued by the United Nations (...
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...
Anna Michalak’s team combined sampling and satellite-based observations of Lake Erie with computer simulations and determined that the 2011 record-breaking algal bloom in the lake was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake...
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...
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....
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-...
