A study by WCS field scientists in the park found that the presence of a single road in a protected area and the subsidies provided by oil companies to local people can fundamentally change how indigenous communities use their resources by providing both access to deeper parts of the forest and a cheap means of getting meat to nearby wildlife markets.

New Carbon Dioxide Data Helps Unlock The Secrets Of Antarctic Formation

Another Factor that Impacts our Climate
September 13, 2009 11:09 AM - R. Greenway, ENN

UCLA atmospheric scientists have discovered a previously unknown basic mode of energy transfer from the solar wind to the Earth's magnetosphere. The research, federally funded by the National Science Foundation, could improve the safety and reliability of spacecraft that operate in the upper atmosphere. "It's like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.

Two German cargo ships have successfully navigated across Russia's Arctic-facing northern shore from South Korea to Siberia without the help of icebreakers, the shipping company said. The two merchant ships belonging to Beluga Shipping Gmbh were able to make the cost-saving voyage by the fabled Northeast Passage because of the reduction in the polar ice cap due to global warming, the company said.

India Could Halve Emissions Growth, at a Cost
September 10, 2009 07:32 AM - Anna da Costa, Worldwatch Institute

Growth in India's carbon emissions could be nearly halved by the year 2030 through the use of known practices and technologies, according to a new report from McKinsey & Company. Through a "step-change in...efforts to lower emissions," India's carbon output could grow from 1.6 billion tons in 2005 to only 2.8 billion tons in 2030 as the country's population expands and its economy develops, the report said. This is down from a previously projected 5-6 billion tons for 2030.

China's increasing air pollution has cut the light rainfall essential to the country's agriculture over the last 50 years, new research suggests.

Fish Farms Supply 50% of Global Harvest
September 8, 2009 11:45 AM - R. Greenway, ENN

Fish farms, once a fledgling industry, now account for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while getting more efficient, it is putting strains on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the online edition of the Proceedings of the National Academy of Sciences.
