Scientists: stop treating population growth as a ‘given’ and empower women
Posted by Washington Post: Juliet Eilperin on February 27th, 2013
Mongabay: Climate change, biodiversity loss, resource depletion, water scarcity, and land issues: almost all of the world's environmental problems are underpinned by too many people inhabiting a finite planet. A new study in the Proceedings of the Royal Society B warns that overpopulation-combined with over-consumption-is threatening to push the entire globe into "a collapse of global civilization." But cultural changes, especially more empowerment of women and access to contraceptives, may hold the key to...

Comments Off on Scientists: stop treating population growth as a ‘given’ and empower womenEstimates reduce amount of additional land available for biofuel production by almost 80%
Posted by Washington Post: Juliet Eilperin on February 27th, 2013
ScienceDaily: Amid efforts to expand production of biofuels, scientists are reporting new estimates that downgrade the amount of additional land available for growing fuel crops by almost 80 percent. Their report appears in the ACS journal Environmental Science & Technology.
Steffen Fritz and colleagues explain that growing concern exists in the U.S. and the European Union on how production of biofuels will impact food security. This has led to a realization that increased production of biofuels must take...

Public Radio International: Lakes high in the world's mountains are becoming increasingly dangerous to the towns that have sprouted up near them. The lakes are prone to floods, typically caused when the mountain glaciers that feed them shed a chunk of ice and rock, forcing thousands of gallons over the banks.
The hamlet of Carhuaz, in Peru's Cordillera Blanca Range, could hardly be more picturesque.

Posted by EnergyWire: Gayathri Vaidyanathan on February 27th, 2013
EnergyWire: Concerns have cropped up in recent years that the methane leaks from oil and gas fields could be large enough to pose a significant climate threat. In various studies, scientists have estimated that anywhere between 1 and 10 percent of natural gas produced leaks through wellheads, transmission lines and compressor stations. Recent measurements from the Uinta Basin of Utah taken by the National Oceanic and Atmospheric Administration set leakage as high as 9 percent. Now, preliminary results are...

Reuters: The signs of rising water are everywhere in this seaport city: yellow "Streets May Flood" notices are common at highway underpasses, in low-lying neighborhoods and along the sprawling waterfront.
Built at sea level on reclaimed wetland, Norfolk has faced floods throughout its 400-year history. But as the Atlantic Ocean warms and expands, and parts of the city subside, higher tides and fiercer storms seem to hit harder than they used to.
Dealing with this increased threat has put Norfolk at...

Posted by Guardian: Kate Hodal on February 27th, 2013
Guardian: An international rights group is pressing Thailand to investigate the recent murder of an environmentalist who exposed the dumping of toxic waste, and condemned the government's "fundamental failure" to protect activists fighting for social and environmental change in the kingdom.
Prajob Nao-opas, 43, was shot four times in broad daylight in Chacheongsao province, 20 miles east of Bangkok, after spending the past year fighting illegal toxic waste disposal by various industrial estates in the region....

Posted by SciDevNet: Naimul Haq on February 27th, 2013
SciDevNet: By combining aquaculture with wet paddy farming in its coastal areas Bangladesh can meet food security and climate change issues, says a new report. The approach promises more nutritious food, without causing environmental damage, and has the potential for a 'blue-green revolution' on Bangladesh's existing crop areas extending to about 10.14 million hectares and an additional 2.83 million hectares that remain waterlogged for about 4--6 months. "The carrying capacities of these additional lands...
Ex-wildlife chief warns of climate change in SC
Posted by The State: Sammy Fretwell on February 27th, 2013
The State: Following revelations the state wildlife department has failed to release a major climate change report, the agency's former chief said the department should be leading efforts to brace South Carolina for the consequences of global warming.
John Frampton, who left the Department of Natural Resources last year, said that the Earth's rising temperatures will undoubtedly affect the state's landscape and wildlife in coming years and that the DNR is well qualified to examine the impacts in South Carolina....
Storm that buried Plains slams Great Lakes region
Posted by Washington Post: Juliet Eilperin on February 27th, 2013
Reuters: A powerful winter storm that buried the U.S. Plains and left at least three people dead moved on Tuesday into the southern Great Lakes region, where it snarled the evening commute in Chicago and Milwaukee, created near-whiteout conditions and forced hundreds of flight cancellations.
Much of the region was under either a winter storm warning or a winter weather advisory, according to the National Weather Service, as the system's potent blend of wet snow, sleet and strong winds bore down on north...
Killer Heat Waves and Floods Linked to Climate Change
Posted by Washington Post: Juliet Eilperin on February 27th, 2013
Inter Press Service: Killer heat waves, floods and storms are increasingly caused by climate change, new research reveals.
Scientists in Germany say they have found how greenhouse gases from burning fossil fuels are helping to trap the jet stream, resulting in extraordinary weather such as the 2010 Pakistan flood and the 2011 heat wave in the United States.
Human-driven climate change repeatedly disturbs the flow of atmospheric waves around the globe`s Northern hemisphere, said lead author Vladimir Petoukhov of...
