Biofuels: More than just ethanol
As the United States looks to alternate fuel sources, ethanol has become one of the front runners. Farmers have begun planting corn in the hopes that its potential new use for corn will be a new income source. view more (2007-04-06)
Scrubbing sulfur
The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. view more (2009-08-18)
Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
Tropical deforestation is the source of nearly a fifth of annual, human-induced emissions of heat-trapping gases to the atmosphere. view more (2007-05-16)
Biofuels: An advisable strategy?
Biofuels have been an increasingly hot topic on the discussion table in the last few years. In 2003 the European Union introduced a Directive suggesting that Member states should increase the share of biofuels in the energy used for transport to 2% by 2005 and 5.75% by 2010. view more (2007-03-08)
Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature. view more (2006-09-08)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at Earth Systems Processes, a multidisciplinary... view more... (2001-06-21)
First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. view more (2007-11-15)
Family planning a major environmental impact
Some people who are serious about wanting to reduce their "carbon footprint" on the Earth have one choice available to them that may yield a large long-term benefit - have one less child. view more (2009-08-03)
Getting Warmer? Prehistoric Climate Can Help Forecast Future Changes
The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature. view more (2008-11-25)
Simple measures can yield big greenhouse gas cuts, scientists say
New technologies and policies that save energy, remove atmospheric carbon and limit greenhouse gas emissions are needed to fight global climate change - but face daunting technological, economic and political hurdles, a Michigan State University scientist said. view more (2009-10-27)
Unlocking the secrets of the seafloor: The future of scientific ocean drilling
Close to 600 scientists from 21 countries met Sept. 23 - 25 2009 in Bremen, Germany, to outline major scientific targets for a new and ambitious ocean drilling research program. view more (2009-09-30)
Carnegie Mellon studies how climate change impacts food production
The old adage, "We are what we eat,'' may be the latest recipe for success when it comes to curbing the perils of global climate warming. view more (2008-04-22)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and vice-versa. view more (2008-02-27)
Keeping the environment clean with compressed air
Savings of up to 50 per cent possible / 320 000 compressors currently in use EU-wide / Complex management structures Annually, the production of compressed air accounts for about 10 per cent of total industrial electricity consumption in the European Union. This corresponds to over 80 billion kilowatt hours per year. In spite of this high figure,... view more... (2001-03-02)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
New report cites ethics and justice as critical in world's approach to climate change
Ethics, human rights, and distributive and procedural justice must be an integral component of international negotiations seeking any comprehensive solution to climate change, according to a new report released here today at the United Nations Climate Change Conference. view more (2006-11-08)
Climatic change and environmental functions of forests
The situation in Navarre with regard to climatic change is one of concern given that gas emissions from the greenhouse effect are even greater than the average in Spain (45%). view more (2006-05-03)
Vehicle emissions monitoring validates inspection program and offers policy insights
A long-term Georgia Institute of Technology study continues to validate the effectiveness of Georgia's vehicle emissions inspection program in 13 metro Atlanta counties that are part of a federal ozone level non-attainment area. view more (2007-06-18)
