Marshes on U.S. Coast Need More Protection NOW
December 27, 2012 09:52 AM - Roger Greenway, ENN
A hundred years ago we thought that we had to fill in the marshes near populated areas along the eastern US coastline since they represented prime locations for commercial and residential development. Even after some protections were put in place to reduce the impacts of runaway development, marshes continued to serve are the places we dumped our garbage, and sent the effluents from our wastewater treatment plants. They also receive the nutrient-rich run off from agricultural land use and urban street runoff to our rivers. A major nine-year study led by researcher Linda Deegan points to the damage that human-caused nutrients inflict on salt marshes along the U.S. East Coast. In a Yale Environment 360 interview, she describes what these findings mean for an ecosystem that provides critical services, from nourishing marine life to buffering the coast from storms like Sandy.
University of Hawaii Comes to Aid of Hurricane Sandy Victims
December 23, 2012 06:35 AM - Roger Greenway, ENN
Hurricane Sandy caused more damage than many people who are not living in the Staten Island and Jersey Shore areas are aware of. It will take a long time to recover and help is still needed. The University of Hawaii may take the title of the helpers who traveled the greatest distance to help. Their mission was two-fold, to help recovery efforts, and to learn what more might be done to reduce damages from future hurricanes and superstorms like Sandy. From November 29 to December 6, 2012, UH Manoa team members from the National Disaster Preparedness Training Center (NDPTC), Sea Grant and the Urban Resilience Lab traveled to the most severely damaged areas in New York City and New Jersey coastal communities to support the Federal Emergency Management Agency (FEMA) and the National Oceanic Atmospheric Administration's (NOAA) efforts in recovery from Hurricane Sandy. Sandy, the most devastating storm to hit the northeastern U.S. coast in decades, struck on November 29. The team assessed and documented damage and met with community leaders, emergency responders, hazard planners and those involved in relief and recovery efforts. Coastal storm surge, flooding and infrastructure failure were the main causes and consequences of Sandy's impact.
EPA Finalizes Clean Air Standards for Boilers and Incinerators, Makes Progress in Protecting Public Health
December 21, 2012 12:30 PM - Editor, ENN
Today, the U.S. EPA finalized changes to Clean Air Act standards for boilers, incinerators, and cement kilns which are used by industries for everything from power generation, heating, treating waste, and manufacturing. These changes will achieve extensive public health protections by reducing toxic air pollution, while at the same addressing concerns and feedback from industry and labor groups, increasing the rule’s flexibility and dramatically reducing costs. As a result, 99 percent of the approximately 1.5 million boilers in the U.S. are not covered or can meet the new standards by conducting periodic maintenance or regular tune-ups.
By harnessing an innovative mix of tools and approaches, governments can strengthen the economies of urban areas and improve their overall livability, according to research presented in the Worldwatch Institute’s State of the World 2012: Moving Toward Sustainable Prosperity. Today, nearly 1 billion of the world’s poor live in urban areas that are dangerously overcrowded and lack adequate access to basic sanitation and clean water, with wide-ranging health and environmental impacts. But even in wealthier countries, governments face serious challenges in making their cities more inclusive, sustainable, and livable. In 2010, informal urban settlements, known more commonly as slums, housed approximately one-third of the urban population of developing countries. "Slum populations are often viewed as an eyesore, but few realize that the urban poor are at the core of a city’s economy, accounting for a large share of employment and performing essential functions for the city," said Eric Belsky, Managing Director of Harvard University’s Joint Center for Housing Studies and State of the World 2012 contributing author.
How Can the Performance of Batteries in Electric Cars be Improved?
December 18, 2012 06:10 AM - Roger Greenway, ENN
I have been driving a Chevy VOLT for a year and a half. I have more than 26,000 miles on it, and have used 100 gallons of gasoline. That works out to more than 250 mpg. Of course, I have been charging the VOLT at home every night, and at the office during the day but my electric bills at both places are not noticeably higher. It would be nice if the electric range were a bit longer, but the gasoline engine on board that charges the batteries guarantees that I can keep driving as long as I need to. What are the limiting factors to increasing the range of the lithium ion batteries? Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes — in the "current collector," a sheet of copper which facilitates electron transfer between the electrodes and the car's electrical system. This knowledge could aid in improving design and performance of batteries, explained Bharat Bhushan, Ohio Eminent Scholar and the Howard D. Winbigler Professor of Mechanical Engineering. "Our study shows that the copper current collector plays a role in the performance of the battery," he said.
Vegetables in Israel Carry Heavy Pesticide Residue
December 16, 2012 08:14 AM - Miriam Kresh, Green Prophet
Are Israelis eating a mouthful of pesticides for breakfast? If there's one food group that Israelis love, it's vegetables. In fact, all over the Middle East, vegetables are treated with love and presented at table in infinite artful ways. And people are picky about their produce, carefully inspecting each tomato and cucumber before consenting to buy. But health hazards lurk on the well-loved produce. According to Haaretz, 11% of produce tested by the Israel Health Ministry showed unacceptably high levels of pesticide residues. Of over 5000 samples taken from 108 kinds of foods, 56% had traces of different pesticides.
EPA Reviews PM2.5 Standards, Expects Counties to Comply by 2020
December 14, 2012 02:50 PM - Allison Winter, ENN
The U.S. Environmental Protection Agency (EPA) finalized an update to its national air quality standards for PM2.5 today, setting the annual health standard at 12 micrograms per cubic meter. PM2.5 is the term used for particulate matter with a diameter of 2.5 micrometers (which is approximately 1/30th of the width of a human hair). It is a harmful fine particle pollutant that comes from wood burning, soot, power plants, and motor vehicles.
The Incredible Elephants of the Sahara
December 14, 2012 09:20 AM - David A Gabel, ENN
African elephants are known for hanging around rivers and mashes in the savanna and the edge of jungles. However, their range actually extends well into the north, all the way up to the Sahara desert. In Mali’s Gourma region, around the city of Timbuktu, there exists a species of desert-adapted African elephant (Loxodonta Africana). Every year, they undertake an amazing migration across an area of 32,000 square kilometers (over 12,000 square miles) in search of food and water. This annual journey was recently recorded by researchers from the group Save the Elephants, University of British Columbia, and Oxford University, who attached GPS collars to nine of the elephants and tracking them by satellite. Their report documents the elephants’ record-breaking trek to survive in the largest and harshest elephant range in the world.
Lawsuit Targets $3 Billion in U.S. Funding for Fossil Fuel Project in Australia's Great Barrier Reef
December 14, 2012 08:52 AM - Editor, Center for Biological Diversity
Conservation groups filed a lawsuit today challenging the U.S. Export-Import Bank's nearly $3 billion in financing for a massive Australian fossil fuel facility in the Great Barrier Reef World Heritage Area. Construction and operation of the liquefied natural gas facility will threaten sea turtles, dugongs and many other protected marine species, as well as the Great Barrier Reef itself.
Britain Lifting Ban on Shale Gas Exploration
December 14, 2012 06:10 AM - EurActive
Britain lifted its ban on shale gas exploration this week despite environmental fears as it aims to become a European leader in a sector that has transformed the U.S. energy market. The approval of shale gas fracking from Energy and Climate Change Secretary Edward Davey comes approximately a year and a half after UK authorities halted the unconventional exploration process after it set off earth tremors at one site. Shale reserves have been viewed as a way to counter the UK's fall in natural gas production. Europe's largest gas consumer, Britain in May 2011 put a temporary stop to hydraulic fracturing or "fracking" for shale gas after earth tremors were measured near the site close to Blackpool.
