An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas. John Downing, an Iowa State University professor in the ecology, evolution and organismal biology department, is part of an international team that concluded that methane release from inland waters is higher than previous estimates. The study, published in the journal Science, indicates that methane gas...

By Diana Lutz , Washington University in St. Louis It sounds a bit like spinning straw into gold, but novel metal catalysts may be able to turn greenhouse gases like methane and carbon dioxide into liquid fuels without producing more carbon waste in the process. If fossil fuels burn completely, the end products are carbon dioxide and water. Today the carbon dioxide is a waste product, one that goes into the air "” adding to global warming; or the oceans "” acidifying them; or...

Innovative research technique reveals C4 grasses older than previously thought A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

Leaks from carbon dioxide injected deep underground to help fight climate change could bubble up into drinking water aquifers near the surface, driving up levels of contaminants in the water tenfold or more in some places, according to a study by Duke University scientists. Based on a year-long analysis of core samples from four drinking water aquifers, "We found the potential for contamination is real, but there are ways to avoid or reduce the risk," says Robert B. Jackson, Nicholas...

A team of researchers are planning to try and help dairy farmers cut greenhouse gas emissions like methane. Nitrogen and carbon based greenhouse gases are produced through a complicated system at dairy farms that is affected by everything from the weather to the soil to the feed to cow burps, along with other things. "Cows emit most of their methane through belching, only a small fraction from flatulence," said the project's principal investigator, Ruth Varner of University of New Hampshire...

NASA has announced the successful activation of new hardware that will support water production services aboard the International Space Station. The Sabatier system can create up to 530 gallons of water per year from byproducts of the station's Oxygen Generation System and Carbon Dioxide Removal Assembly. The process is named for Paul Sabatier, a 1912 Nobel Prize winner in chemistry. "This is an important step forward in NASA's commercialization endeavors and shows how successful private...

Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide. The study, conducted by Andrew Lacis and colleagues at NASA's Goddard Institute for Space Studies (GISS) in New York, examined the nature of Earth's greenhouse effect and clarified the role that greenhouse gases and clouds play in absorbing outgoing infrared...

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
