A new study, "Mission-Driven Research for Stratospheric Aerosol Geoengineering," published in Proceedings of the National Academy of Sciences, sets out to establish a roadmap for responsible exploration of geoengineering.
National Renewable Energy Laboratory (NREL) researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made US reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings, published in the journal Environmental Science & Technology, reveal for the first time the potential for floating PV to produce electricity in the United States.
Doctors Without Borders and Occupational Knowledge International are reporting on a successful pilot project demonstrating significant gains in reducing severe lead poisoning in mining communities in Nigeria. Since 2010 MSF has been treating thousands of poisoned children in response to the world's worst lead poisoning outbreak in Northern Nigeria. The introduction of safer mining practices reduced airborne lead concentrations by 95 percent according to the findings published in Annals of Work Exposures and Health.
The latest climate models and observations offer unprecedented opportunities to reduce the remaining uncertainties in future climate change, according to a paper published in Nature Climate Change by a team of 29 international authors.
Due to a scarcity of data, most global estimates of ocean warming start only in the 1950s. However, a team of scientists at the University of Oxford has now succeeded in reconstructing ocean temperature change from 1871 to 2017.
Every year, thousands of Magellanic penguins are stranded along the South American coast--from northern Argentina to southern Brazil -- 1,000 kilometers away from their breeding ground in northern Patagonia. Now researchers reporting in Current Biology on Jan. 7 have new evidence to explain the observation that the stranded birds are most often female: female penguins venture farther north than males do, where they are apparently more likely to run into trouble.
Why did nearly one-quarter of eligible residents in Detroit turn down free street trees? That's the mystery UVM researcher Christine Carmichael solves in one of the first studies to explore opposition to city tree planting programs. As cities from New York to L.A. embark on tree planting initiatives, the research helps to explain why more than 1,800 of 7,425 eligible Detroit residents -- roughly 25 percent -- submitted 'no-tree requests' between 2011 and 2014 alone.
Researchers show that up to 15 million hectares of forest risk losing protection owing to a new clause in the law under which state governments can let private landowners protect only 50 percent of their property, down from 80 percent previously, if over 65 percent of the state is protected by conservation units or indigenous reservations.
Urban planners should plant hedges, or a combination of trees with hedges -- rather than just relying on roadside trees -- if they are to most effectively reduce pollution exposure from cars in near-road environments, finds a new study from the University of Surrey.
