Does the public trust what scientists say?
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm. >> Read the Full Article
What's best for creating drought resistant plants? Traditional breeding or GM?
Reports show that traditional breeding techniques are years ahead of GM technologies in developing crops to withstand drought and poor soils, writes Lawrence Woodward. Yet GM advocates are sticking rigidly to their script even as the evidence mounds against them. Since its launch in 2010, the Improved Maize for African Soils Project (IMAS) has developed 21 conventionally bred varieties which have increased yield by up to 1 tonne per hectare. >> Read the Full Article
California Becomes 1st State to Ban Plastic Bags
It's official: California is now the first state in the country to institute a statewide plastic bag ban! Though it took years for state legislators to pass this bill plus an additional month that felt like an eternity for the governor to sign the bill into law, environmentalists can finally rejoice in the knowledge that grocery store plastic bags will soon be a thing of the past. Analysts expect the legislation will eliminate at least 13 billion plastic bags per year. Don't expect to see a change immediately, however: the ban won't go into effect until next July. Liquor and convenience stores will have until July of 2016 to switch to paper or reusable bags. >> Read the Full Article
Climate Change and Food Security
If coping with climate change is central to achieving a sustainable future for the global population, then food security lies at the heart of this effort, FAO Director-General JosÃ© Graziano da Silva said last week in a speech at the United Nations Climate Summit last week. "We cannot call development sustainable while hunger still robs over 800 million people of the opportunity to lead a decent life," he said in a reference to the latest U.N. report on world hunger, The State of Food Insecurity in the World 2014. >> Read the Full Article
Renewable energy capacity increases, nuclear declines
Advocates of nuclear energy have long been predicting its renaissance, yet this mode of producing electricity has been stalled for years. Renewable energy, by contrast, continues to expand rapidly, even if it still has a long way to go to catch up with fossil fuel power plants, writes Worldwatch Institute Senior Researcher Michael Renner in the Instituteâ€™s latest Vital Signs Online analysis (bit.ly/NuclearRE). Nuclear energyâ€™s share of global power production has declined steadily from a peak of 17.6 percent in 1996 to 10.8 percent in 2013. Renewables increased their share from 18.7 percent in 2000 to 22.7 percent in 2012. >> Read the Full Article
Connecting Productivity of Office Workers and Climate Change
Energy efficiency in office buildings struggles to gain the attention of top management, writes John Alker - because energy is too cheap to really matter. But with 90% of operating costs spent on staff, a new report shows that green building design makes employees happier and more productive. There would seem to be no connection between the productivity of office workers and the great challenge of climate change. But a report published by the World Green Building Council suggests otherwise. >> Read the Full Article
Reducing global trade would cut carbon emissions
If the world's leaders really cared about climate change, there's one easy way to reduce emissions, writes John Weeks - drop the obsession with increasing trade, and all the pollution that goes with it. A world based on local production, consumption and finance will be a better one for people and the environment. Let us join Keynes to imagine if we can a world in which goods are 'homespun' and finance is 'primarily national'. If we cannot imagine such a world, there is little hope for the planet. The Obama administration has proposed several ad hoc multi-country economic agreements, and in doing so has abandoned de facto the World Trade Organization (WTO) as insufficiently malleable to its interests. >> Read the Full Article
A concrete idea: MIT develops better, greener, concrete
Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half - and the result would be a stronger, more durable material. The findings come from the most detailed molecular analysis yet of the complex structure of concrete, which is a mixture of sand, gravel, water, and cement. Cement is made by cooking calcium-rich material, usually limestone, with silica-rich material - typically clay - at temperatures of 1,500 degrees Celsius, yielding a hard mass called "clinker." This is then ground up into a powder. The decarbonation of limestone, and the heating of cement, are responsible for most of the material's greenhouse-gas output. >> Read the Full Article
Seattle Assesses Fine for Wasting Food
The push for increased sustainable methods can be seen everywhere these days â€” certainly when it comes to local efforts to pare down on what we toss in the landfill. The city of Seattle has also embraced the composting idea with a bit more of a creative edge: In an effort to encourage residents to stop wasting food, the city council passed an ordinance this last Monday that allows households to be fined $1 each time that garbage collectors find more than 10 percent of organic waste in their garbage bins. >> Read the Full Article
Whooping Cranes being raised and released by the US Geological Survey
Four whooping crane chicks raised in captivity began their integration into the wild Saturday as part of the continuing effort to increase the wild population of this endangered species. The cranes, hatched and raised by their parents at the U.S. Geological Survey's Patuxent Wildlife Research Center in Laurel, Maryland, were released on the U.S. Fish and Wildlife Service's Necedah National Wildlife Refuge in Wisconsin. >> Read the Full Article
