Global Ecology Stories
In the face of global climate change, increasing the use of renewable energy resources is one of the most urgent challenges facing the world. Further development of one resource, solar energy, is...
To combat global climate change caused by greenhouse gases, alternative energy sources and other types of environmental recourse actions are needed. There are several proposals that involve using...
Washington, DC— You know the old saying: Location, location, location? It turns out that it applies to the Amazon rainforest, too. New work from Carnegie’s Greg Asner ...
You know the old saying: Location, location, location? It turns out that it applies to the Amazon rainforest, too. New work illustrates a hidden tapestry of chemical variation across the lowland...
Mongabay covers the launch of Greg Asner's third-generation Carnegie Airborne Observatory, and the possiblity that he'll tackle mapping in drought-stricken California and Malaysian...
Artificially manipulating Arctic climate by 'whitening' the ocean's surface to reflect sunlight back into space will fail, Carnegie's Ken Caldeira tells The Independent....
Washington, D.C.—Joseph A. Berry, staff scientist at Carnegie’s Department of Global Ecology, has been elected to the National Academy of Sciences, one of 84 new members and 21 foreign...
Washington, D.C.— Some scientists have suggested that global warming could melt frozen ground in the Arctic, releasing vast amounts of the potent greenhouse gas methane into the atmosphere,...

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...
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...
Ken Caldeira was a Carnegie investigator from 2005 to 2020 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....
Anna Michalak joined Carnegie in 2011 from the Department of Civil and Environmental Engineering at the University of Michigan. She was named Director of the Department of Global Ecology in 2020. Her research focuses on characterizing complexity and quantifying uncertainty in environmental systems...

Washington, D.C.— In many ways, plants act as chemical factories, using energy from sunlight to produce carbon-based energy and taking nutrients from the soil in order to synthesize a wide variety of...
"It’s true that right now our fossil-fuel resources remain vast; but it’s also true that, if we keep burning through them at current rates, they’ll be gone in less time than it...
Washington, D.C.— A great deal of research has focused on the amount of global warming resulting from increased greenhouse gas concentrations. But there has been relatively little study of the pace...
