New Carbon Dioxide Data Helps Unlock The Secrets Of Antarctic Formation

The link between declining CO2 levels in the earth's atmosphere and the formation of the Antarctic ice caps some 34 million years ago has been confirmed for the first time in a major research study.

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.

German ships successfully make "Arctic Passage"

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.

Comment on "$20 Per Gallon"
September 7, 2009 09:42 AM - M Molendyke, ENN Community

Not often is a book written that can explain the intricacies and effects of economics, international relations, and the green movement, and how the three impact the sociology of our country and our world. However, in his recently released book “$20 Per Gallon,” Christopher Steiner does just that, and makes it interesting and funny to boot.

Methane Gas Could Increase From Oceanic Vents
September 6, 2009 08:03 AM - Roger Greenway, ENN

New MIT research by Denise Brehm, Department of Civil and Environmental Engineering, funded by the U.S. Department of Energy looked at the potential for a compound affect of warming global temperatures on the level of methane being released by oceanic vents. The premise is that rising global temperatures could be accompanied by melting permafrost in arctic regions and that this could initiate the release of underground methane into the atmosphere. Once released, that methane gas would speed up global warming by trapping the Earth's heat radiation about 20 times more efficiently than does the better-known greenhouse gas, carbon dioxide.
