Global Ecology Stories
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...
Washington, D.C.— Could replacing coal-fired electricity plants with generators fueled by natural gas bring global warming to a halt in this century? What about rapid construction of massive numbers...
Washington, D.C.—By combining airborne laser technology, satellite mapping, and ground-based plot surveys, a team of researchers has produced the first large-scale, high-resolution estimates of...
Washington, D.C. — Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter. There are concerns that a...

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...
The Carnegie Airborne Observatory (CAO), developed by GregAsner, is a fixed-wing aircraft that sweeps laser light across the vegetation canopy to image it in brilliant 3-D. The data can determine the location and size of each tree at a resolution of 3.5 feet (1.1 meter), a level of detail that is...
Until now, computer models have been the primary tool for estimating photosynthetic productivity on a global scale. They are based on estimating a measure for plant energy called gross primary production (GPP), which is the rate at which plants capture and store a unit of chemical energy as biomass...
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...
Greg Asner is a staff scientist in Carnegie's Department of Global Ecology and also serves as a Professor in the Department of Earth System Science at Stanford University. He is an ecologist recognized for his exploratory and applied research on ecosystems, land use, and climate change at...
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....

Washington, D.C.— Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New work...
Washington, D.C. — Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and...
Degraded forests play a crucial role in the future survival of Bornean elephants. A new study from the Carnegie Airborne Observatory team paired GPS tracking data for 29 elephants with airborne...
