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...

Award Recognizes City's Achievement in Addressing Climate Change PITTSBURGH, Oct. 25 /PRNewswire-USNewswire/ -- In recognition of its continual work to measure and reduce greenhouse gases, Pittsburgh has received a "Milestone Five" Award from ICLEI: Local Governments for Sustainability. In ICLEI's Five Milestone program, local governments commit to inventory greenhouse emissions, set realistic reduction goals, develop and implement hands-on climate action plans that yield results, and...

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...

Australian scientists said Monday they are planning to develop a "molecular sponge" which they hope will soak up carbon gases and help fight greenhouse gas pollution. Researchers at Sydney University have produced crystals full of small holes that can soak up gases like carbon dioxide, which they believe will eventually be used in places where these gases are produced. "You could think of them a little bit like your kitchen sponge," lead researcher and postdoctoral fellow Deanna...

Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a Penn State dairy scientist. In a series of laboratory experiments and a live animal test, an oregano-based supplement not only decreased methane emissions in dairy cows by 40 percent, but also improved milk production, according to Alexander Hristov, an associate professor of dairy nutrition. The natural methane-reduction supplement could lead to a cleaner environment and more...

A new discovery by scientists at the Universities of East Anglia and Frankfurt could make it possible in future to identify the source of banned CFCs that are probably still being released into the atmosphere. Using mass spectrometers, the researchers analyzed air samples collected in the stratosphere by balloons belonging to the French space agency, the Centre National d'Etudes Spatiales (CNES). They discovered the largest chlorine isotope enrichment ever found in nature. CFCs were banned in...

An unusual substance known as "dry water," which resembles powdered sugar, could provide a new way to absorb and store carbon dioxide, the major greenhouse gas that contributes to global warming, scientists reported August 25th at the 240th National Meeting of the American Chemical Society. The powder shows bright promise for a number of other uses, they said. It may, for instance, be a greener, more energy-efficient way of jumpstarting the chemical reactions used to make hundreds of consumer...

Within the sludge of wastewater treatment plants is an invisible world teeming with microbes. Here, diverse species of bacteria convert solid and liquid wastes into gases, some of which contribute to global warming. Now two Stanford University engineers are developing a new sewage treatment process that would actually increase the production of two greenhouse gases "“ nitrous oxide (aka, "laughing gas") and methane "“ and use the gases to power the treatment plant. "Normally, we...

US Automaker to Switch from HFCs to Climate Friendly Refrigerants WASHINGTON, July 23 /PRNewswire-USNewswire/ -- General Motors has announced that it will convert the air conditioning systems in its entire fleet of Chevrolet, Cadillac, Buick and GM models from using high-GWP (global warming potential) refrigerants to a new refrigerant with a much lower climate impact. The HFC (hydrofluorocarbon) refrigerant currently used in virtually every American model car and truck, HFC-134a has a...

A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. A study by scientists at the Carnegie Institution's Department of Global Ecology, with colleagues from the Research Center Jlich in Germany, has now overturned the conventional belief about how these important structures called stomata regulate water vapor loss from the leaf"“a process called transpiration. They found that radiation is the driving...

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...
