Unlike public opinion polls, the survey focuses on the views of professionals in a position to make or influence large decisions in their organizations and society. This focus, together with the survey’s large global sample, spread across all regions of the world and from governments at all levels, scientific institutions, business, and civil society, makes the survey unique.

Mars rovers find new evidence of "habitable niche"
December 27, 2007 10:49 AM - Cornell Chronicle

Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter -- and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January 2004. Meanwhile, researchers are considering the implications of what Cornell's Steve Squyres, principal investigator for NASA's Mars Exploration Rover mission, calls "one of the most significant" mission discoveries to date: silica-rich deposits uncovered in May by Spirit's lame front wheel that provide new evidence for a once-habitable environment in Gusev Crater.

Fisheries Should Be Regarded As Part Of Maritime Environment, Experts Urge
December 27, 2007 10:38 AM - Helmholtz Association of German Research Centres.

The environmental perspective has already been established in legislation and international conventions on fisheries. However, on the implementation level the ecosystems approach is still in an elementary phase. If fisheries are to be sustainable in the future, new decision-making approaches and structures are needed for ecosystems threatened by fisheries and for regions in which environmental changes threaten the profitability of fisheries. By such measures it is possible to support interaction between various interests and perspectives and to promote versatile use of new information about the maritime environment.

MOGOL, Indonesia (Reuters) - Landslides and floods triggered by heavy rain have left more than 120 people dead or missing on Indonesia's Java island, as rescuers struggled on Thursday to pull out bodies buried under thick mud. Officials said thousands of people have been left homeless after their houses were submerged by floods or buried by landslides in villages near the Bengawan Solo river, which lies about 500 km from the capital, Jakarta.

OSLO (Reuters) - Britain's Prince Charles has offered to team up with Norway in projects to save forests around the world, Norwegian officials said on Thursday. The Prince of Wales's offer to Norwegian Prime Minister Jens Stoltenberg followed Norway's announcement earlier this month that it aimed to provide about 3 billion crowns ($541.2 million) per year to prevent deforestation in developing countries.

Broken Homes Damage the Environment
December 26, 2007 12:45 PM - Michigan State University Newswire

The data are in. Divorce is bad for the environment. A novel study that links divorce with the environment shows that a global trend of soaring divorce rates has created more households with fewer people, that, in turn, take up more space and gobble up more energy and water. The research of Jianguo "Jack" Liu and Eunice Yu at Michigan State University, which was partially funded by the National Science Foundation, appears in this week's online edition of the Proceedings of the National Academy of Sciences.

Climatic Chain Reaction Caused Runaway Greenhouse Effect 55 Million Years Ago
December 26, 2007 10:55 AM - Utrecht University

Analogous to the Earth's current situation, greenhouse warming 55 million years ago was caused by a relatively rapid increase of CO2 concentrations in the atmosphere. This phase, known as the Paleocene-Eocene thermal maximum (PETM), was studied using sediments that accumulated 55 million years ago on the ocean floor in what is now New Jersey. The new study shows that a large proportion of the greenhouse gases was released as a result of a chain-reaction of events. Probably due to intense volcanic activity, CO2 concentrations in the atmosphere became higher and the ensuing greenhouse effect warmed the Earth.

The Danger of PBDEs
December 25, 2007 10:34 PM - UC Riverside

Riverside, California - Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa. Now, they are being found in alarming concentrations, in human blood and breast milk - a potentially major concern for human health. In addition, these industrial chemicals have been associated with cases of feline hyperthyroidism, a potentially fatal condition in cats.

China says is no threat to world energy security
December 25, 2007 09:23 PM - Reuters

BEIJING (Reuters) - China said it is not a threat to world energy security and energy issues should not be politicized, urging that conflicts in producing nations be resolved through dialogue and not military force. China, the world's second-largest oil consumer, also is too reliant on international crude markets for last minute oil supplies and needs to arrange more long-term deals, Beijing said in a policy paper released on Wednesday. "China did not, does not and will not pose any threat to the world's energy security," according to the paper, titled China's Energy Conditions and Policies. "China will, step by step, change the current situation of relying too heavily on spot trading of crude oil, encourage the signing of long-term supply contracts with foreign companies and promote the diversification of trading channels," the paper added.
