Washington, DC— There is considerable opportunity for generating wind power in the open ocean, particularly the North Atlantic, according to new research from Carnegie’s Anna Possner and Ken Caldeira. Their work is published by Proceedings of the National Academy of Sciences.

Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity.

“Are

Washington, DC— Carnegie’s Ken Caldeira and Geeta Persad are co-recipients of one of nine National Science Foundation grants for research on how humans and the environment interact. The nine projects were awarded $13 million overall.

The Coupled Dynamics of Natural and Human Systems program “considers humans and the environment as one interconnected system,” said the NSF when announcing the grants. The awardees were selected because they “look at ways in which people deal with environmental processes in a range of settings, including coasts, woodlands, and cities.”

As Carnegie’s grantees, Caldeira and Persad aim to help countries optimize how they meet their commitments

Global biological diversity is under enormous and increasing threat from habitat loss caused by land use and climate change. Responding to this problem requires strategies that integrate elements of governance, economics, human welfare, and other societal factors. It also requires the use of geographically explicit approaches to generate safe havens for biodiversity, both in the long-term and as immediate barriers to the ongoing extinction crisis.

Prioritization of new regions for protection is often undertaken with incomplete and/or outdated information on the geography of biodiversity.  In response, Greg Asner and colleagues have created and utilized a novel capability to map

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 circulation and warm temperatures. The bloom began in the western region in mid-July and covered an area of 230 square miles (600 km2). At its peak in October, the bloom had expanded to over 1930 square miles (5000 km2). Its peak intensity was over 3 times greater than any other bloom on record. The scientists predicted that, unless agricultural policies change, the lake will continue to experience

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 (UN) Intergovernmental Panel on Climate Change (IPCC), Working Group II co-chaired by Chris Field, Global Ecology director, with science co-directors Katie Mach and Mike Mastrandrea managing the input of over 190 governments and nearly 2,000 experts from around the world.

The IPCC, established in 1988, assesses information about climate change and its impacts. In September 2008, Field was

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 over a specific time. Joe Berry was part of a team that took an entirely new approach by using satellite technology to measure light that is emitted by plant leaves as a byproduct of photosynthesis as shown by the artwork.

The plant produces fluorescent light when sunlight excites the photosynthetic pigment chlorophyll. Satellite instruments sense this fluorescence yielding a direct

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 potential effects from elevated atmospheric carbon dioxide, elevated temperature, increased precipitation, and increased nitrogen deposition. The site houses experimental plots that replicate all possible combinations of the four treatments and additional sampling sites that control for the effects of project infrastructure. Studies focus on several integrated ecosystem responses to the

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-term evolution of climate and geochemical cycles; climate intervention proposals; and energy technology.

 Caldeira was a lead author for the U.N.’s Intergovernmental Panel on Climate Change (IPCC) AR5 report and was coordinating lead author of the oceans chapter for the 2005 IPCC report on carbon capture and storage. He was a co-author of the 2010 US National Academy America's Climate

Anna Michalak joined Carnegie in 2011 from the Department of Civil and Environmental Engineering at the University of Michigan.
