Some Coal Ash from China Too Radioactive for Reuse
November 10, 2017 11:21 AM - Duke University

Manufacturers are increasingly using encapsulated coal ash from power plants as a low-cost binding agent in concrete, wallboard, bricks, roofing and other building materials. But a new study by U.S. and Chinese scientists cautions that coal ash from high-uranium deposits in China may be too radioactive for this use.

Climate change, sparse policies endanger right whale population

North Atlantic right whales – a highly endangered species making modest population gains in the past decade – may be imperiled by warming waters and insufficient international protection, according to a new Cornell analysis published online in Global Change Biology, Oct. 30.

China's Sulfur Dioxide Emissions Declined Significantly While India's Grew Over Last Decade
November 9, 2017 12:09 PM - University of Maryland

Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. It is produced predominantly when coal is burned to generate electricity.

Geography PhD creates virtual environment for coastal planning project
November 9, 2017 08:09 AM - University of Victoria

What if you could experience the beauty of Sidney Spit (at the northern tip of Sidney Island) without leaving your home? Robert Newell has applied cutting-edge technology to develop a virtual reality experience that takes visitors on a tour of the park, over land and underwater, using visualization tools.

Are the Grandkids Worth It? Climate Change Policy Depends on How We Value Human Population
October 31, 2017 02:29 PM - Princeton University, Woodrow Wilson School of Public and International Affairs

If the human population continues to grow, more pressure will be put on carbon dioxide emissions — leaving future generations vulnerable to the effects of climate change. To head this off, greenhouse gas emissions must be reduced, but that could cost billions of dollars or more over the next few decades, a dilemma plaguing today’s policymakers.

How cities can fight climate change most effectively
October 30, 2017 11:25 AM - Massachusetts Institute of Technology

What are the best ways for U.S. cities to combat climate change? A new study co-authored by an MIT professor indicates it will be easier for cities to reduce emissions coming from residential energy use rather than from local transportation — and this reduction will happen mostly thanks to better building practices, not greater housing density.

Marine Species Threatened by Deep-Sea Mining
October 25, 2017 11:39 AM - University of Gothenburg

Less than half of our planet’s surface is covered by land. The rest is water, and this environment is home to an enormous range of animal species, most of which remain undiscovered and thus have not yet been named.

Exposure to Glyphosate, Chemical Found in Weed Killers, Increased Over 23 Years
October 24, 2017 11:37 AM - University of California - San Diego

Analyzing samples from a prospective study, University of California San Diego School of Medicine researchers found that human exposure to glyphosate, a chemical widely found in weed killers, has increased approximately 500 percent since the introduction of genetically modified crops.

Sea Level Rise Could Flood 1.9 Million U.S. Homes by 2100
October 24, 2017 10:12 AM - Yale Environment 360

An estimated 1.9 million U.S. homes could be flooded by 2100 if seas rise 6 feet in response to climate change, according to a new analysis by the real estate company Zillow. The affected properties are valued at $916 billion dollars and represent 1.8 percent of the country’s housing stock.

Zebra chip pathogen found in Western Canada for the first time
October 24, 2017 08:41 AM - University of Lethbridge

For the first time, evidence of the zebra chip pathogen has been found in potato fields in southern Alberta, but the University of Lethbridge’s Dr. Dan Johnson cautions against panic.

“So far, the zebra chip pathogen has appeared in only small numbers of potato psyllids,” says Johnson, a biogeography professor and coordinator of the Canadian Potato Psyllid and Zebra Chip Monitoring Network. “The number of potato psyllids in all Alberta sites is very low and many sample cards have found no evidence of the potato psyllid insect. Zebra chip does not normally become a problem unless the potato psyllids are found in much higher numbers than are currently being found in Canada.”
