Global Ecology Stories
Washington, DC— Bleached anemones—those lacking symbiotic algae—do not move toward light, a behaviour exhibited by healthy, symbiotic anemones. Published in...
Washington, DC— The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes, which was...
Washington, DC— Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in...
Washington, DC— Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be...
Washington, DC—If power plants, boilers, furnaces, vehicles, and other energy infrastructure is not marked for early retirement, the world will fail to meet the 1.5-degree Celsius climate-...
Washington, DC—Changes in temperature and precipitation have already impacted the amount of nitrogen introduced into U.S. waterways, according to new research from a team of three Carnegie...
Washington, DC—Tiny fragments of plastic in the ocean are consumed by sea anemones along with their food, and bleached anemones retain these microfibers longer than healthy ones, according to...
Washington, DC—Strategies for limiting climate change must take into account their potential impact on water quality through nutrient overload, according to a new study from Carnegie’s...

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...
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’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...
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....
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...

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...
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...
The results from a suite of environmental mercury studies done by the Carnegie Amazon Mercury Project (CAMEP) was used by the Peruvian government for the decision to announce this state of emergency...
