A new study by economists at Oregon State University questions the cost-effectiveness of biofuels and says they would barely reduce fossil fuel use and would likely increase greenhouse gas emissions. The idea that biofuels can reduce dependency on fossil fuels and mitigate climate change has led governments to promote them as substitutes for gasoline and petroleum-based diesel, using mandates and subsidies, said Bill Jaeger, the lead author on the study. "Our results suggest that...

Berkeley Lab scientists help analyze the technological steps needed to create a low-carbon future for the Golden State What will a day in the life of a Californian be like in 40 years? If the state cuts its greenhouse gas emissions 80 percent below 1990 levels by 2050 – a target mandated by a state executive order – a person could wake up in a net-zero energy home, commute to work in a battery-powered car, work in an office with smart windows and solar panels, then return home...

Worldwide Food Demand May Double By 2050
2011-11-22 06:09:56

Researchers at the University of Minnesota´s College of Biological Sciences have calculated that food demands by 2050 may double worldwide. Doubling the world's food production, they predict, will put a strain on the environment by significantly increasing the amount of carbon dioxide and nitrogen produced, which will cause the loss of many species throughout the world. But the paper shows that using high-yield farming techniques and efficient use of nitrogen fertilizers can help...

Scientific experts outline concrete steps toward a sustainable global food system In the lead up to UN global climate talks in Durban, South Africa later this month, an independent global commission of eminent scientists today released a set of concrete recommendations to policy makers on how to achieve food security in the face of climate change. Based on a thorough review of existing research, the commissioners urged immediate, coordinated action toward transforming the food system to...

From the North Pole to the Arctic Ocean, the frozen soils within this region keep an estimated 1,672 billion metric tons of carbon out of the Earth's atmosphere. This sequestered carbon is more than 250 times the amount of greenhouse gas emissions attributed to the United States in the year 2009. As global temperatures slowly rise, however, so too do concerns regarding the potential impacts upon the carbon cycle when the permafrost thaws and releases the carbon that has been trapped for eons....

University of Leicester research into greenhouse gas emissions from oil palm plantations provides robust measures now being used to inform international policies on greenhouse gas emissions A new study on greenhouse gas emissions from oil palm plantations has calculated a more than 50% increase in levels of CO2 emissions than previously thought — and warned that the demand for 'green' biofuels could be costing the earth. The study from the University of Leicester was conducted for...

Improves Electric Reliability; Negligible Impact on Manufacturers Maryland's plan to cut greenhouse gas emissions 25 percent by 2020 meets a series of benchmark tests set by state lawmakers, concludes a new pair of studies by the University of Maryland Center for Integrative Environmental Research (CIER). The findings should help clear the way for adoption of a full Climate Action Plan next year, the researchers say. Maryland's 2009 Greenhouse Gas Reduction Act ordered independent...

Annual Survey Shows Growing Demand for Environmental Products and Green Job Creation Wilmington, Del. (PRWEB) October 10, 2011 DuPontâs recent 2011 Sustainability Progress Report shows the companyâs environmental footprint continues to shrink. DuPont delivered a 75 percent decrease in greenhouse gas emissions and a 6 percent reduction in absolute energy use since 1990, while increasing production 40 percent during that same period*. Increasingly, DuPont is focused...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
