A new tool against illegal logging: tree DNA technology goes mainstream
April 22, 2013 08:47 AM - Tanya Dimitrova, MONGABAY.COM
The role of tree DNA tracking is increasing in the fight against illegal logging as evidenced by prosecution cases in USA and Germany. Modern DNA technology offers a unique opportunity: you could pinpoint the origin of your table at home and track down if the trees it was made from were illegally obtained. Each wooden piece of furniture comes with a hidden natural barcode that can tell its story from a sapling in a forest all the way to your living room.
US Greenhouse Gas Emissions are Down
April 21, 2013 10:01 AM - ANDREW BURGER, Global Warming is Real
Anthropogenic US greenhouse gas emissions (GHG) amounted to a CO2-equivalent 6,702.3 million metric tons in 2011, down 1.6 percent from 2010 and 6.9 percent below 2005 levels. Longer term, US GHG emissions have increased at an annual average rate of 0.4 percent since 1990, according to the Environmental Protection Agency's (EPA) 18th annual US Greenhouse Gas Emissions and Sinks (Inventory) report, which was released April 15. A decrease in the carbon intensity of fuels used in electricity generation due to increased use of natural gas as opposed to coal, a "significant increase in hydropower" generation, and "relatively mild winter conditions, especially in the South Atlantic Region of the US" were the main factors underlying the drop in national GHG emissions in 2011, according to the EPA’s "The Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2011."
Nitrogen Fertilizer Dangers
April 20, 2013 06:42 AM - Dan Charles, NPR
My first reaction when I heard details of this week's deadly fertilizer explosion in Texas was horror. My second thought was, "Maybe I shouldn't have pushed to change that headline." National Geographic magazine just published in its May issue my article about how nitrogen fertilizer has shaped our planet. The article, with Peter Essick's beautiful pictures, describes fertilizer's critical role in providing our food, but also its toll on water, air and wildlife. When the article went up online, the headline read, at first, "The Curse of Fertilizer." I didn't like it. It seemed only half of the story. I complained, and the headline soon changed to "A Mixed Blessing" — just as news broke that the West Fertilizer Co. plant had caught fire and exploded, destroying much of the small town of West, Texas. The blast killed at least a dozen people — including emergency workers who were trying to fight the fire — and injured more than 100 others.
Green 'Khutbah' Muslim Sermon Campaign
April 19, 2013 10:59 AM - Arwa Aburawa, GreenProphet
Muslims have been asked to encourage their spiritual leaders, imams, to devote this Friday Khutbah or sermon (19th April 2013) to celebrate the blessings, graces and beauty of all of Allah’s creation. Muaz Nasir from Khaleafa who is leading the effort is also hoping to raise awareness amongst Muslim of the environmental challenges facing humanity. "The 'Green Khutbah Campaign' is aiming to challenge Muslims to become stewards of the environment by making changes to their daily routines," explains Nasir. "Although the evidence of environmental damage is stronger than ever, the public is starting to tune out due to the recent economic crisis and a lack of political leadership. But Muslims cannot tune out from the environmental damage — tuning out would mean that we are disregarding our moral responsibility to Allah's creation."
Wildlife Sanctuaries Along Coasts and Sea Level Rise
April 19, 2013 06:18 AM - Science Daily
A new report on the potential effects of climate change on NOAA's Olympic Coast National Marine Sanctuary uses existing observations and science-based expectations to identify how climate change could affect habitats, plants and animals within the sanctuary and adjacent coastal areas. It also outlines new management recommendations for the sanctuary, and sanctuary officials called it the first step toward addressing them. They also said the report issued by the sanctuary, Climate Change and the Olympic Coast National Marine Sanctuary: Interpreting Potential Futures, will provide a foundation of information and identify key issues facing the sanctuary.
Seismic Airgun Testing for Oil and Gas Threatens Marine Life and Coastal Economies
April 16, 2013 06:50 AM - Editor, Oceana
According to government estimates, 138,500 whales and dolphins will soon be injured and possibly killed along the East Coast if exploration companies are allowed to use dangerous blasts of noise to search for offshore oil and gas. The U.S. Department of the Interior (DOI) is considering allowing geophysical companies, working on behalf of oil and gas companies, to use seismic airguns to search for offshore oil and gas in the Atlantic Ocean, from Delaware to Florida. These airguns use compressed air to generate intense pulses of sound, which are 100,000 times more intense than a jet engine.
Is Ice Loss by Glaciers Abnormal?
April 15, 2013 06:36 AM - Science Daily
In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences. Previous work by Steig has shown that rapid thinning of Antarctic glaciers was accompanied by rapid warming and changes in atmospheric circulation near the coast. His research with Qinghua Ding, a UW research associate, showed that the majority of Antarctic warming came during the 1990s in response to El Niño conditions in the tropical Pacific Ocean.
Britain's love affair with bottled water
April 11, 2013 11:49 AM - David Gray, The Ecologist
Leading academic brands industry a "scam" as campaigners condemn our growing thirst for bottled water. The UK bottled water industry releases 350,000 tonnes of carbon dioxide into the atmosphere each year. One of Britain's leading authorities on water supplies has branded the bottled water industry a scam, backing campaigners' claims of wasted millions and environmental pollution at a time when tap water standards have never been higher. Professor Paul Younger, Rankine Chair of Engineering at Glasgow University, has highlighted growing fears that our increasing consumption of bottled water is damaging the environment while raising huge profits for the big brands, despite Britain having one of the best mains water supplies in the world.
EU Looking Favorably on Shale Gas Development
April 11, 2013 06:09 AM - Anne Glover, EurActiv
The EU’s chief scientific advisor has said that evidence allows the go-ahead for extracting shale gas, the energy source at the centre of a European policy tug-of-war. The EU executive launched a green paper on 27 March, setting out Europe's energy and climate aims for 2030, with Energy Commissioner Günther Oettinger taking a favourable position on shale gas. "I am in favour of producing shale gas, particularly for safety reasons, and to reduce gas prices," he said. "In the United States, which is a big producer of shale gas, the price of gas is four times less than in Europe."
Global Forest Watch 2.0 will help monitor our forests
April 10, 2013 06:36 AM - Editor, MONGABAY.COM
World Resources Institute (WRI) today unveiled a long-awaited tool that could revolutionize global forest monitoring, reports the UN Forum on Forests, which is meeting this week in Istanbul, Turkey. Global Forest Watch 2.0 is a platform that combines near-real time satellite data, forestry data, and user-submitted information to provide the most complete picture of the world's forests ever assembled. The system has been developed over the last several years as a collaborative effort between WRI and other partners, including Google, the University of Maryland and the UN Environment Programme (UNEP).
