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...

Anaerobic manure treatment lagoons may release more methane than current rules allow The approach the U.S. Environmental Protection Agency (EPA) uses to estimate greenhouse gas emissions from agricultural anaerobic lagoons that treat manure contains errors and may underestimate methane emissions by up to 65%, according to scientists from the University of Missouri. Anaerobic lagoons treat manure on some animal feeding operations prior to application to crops as a fertilizer. Methane, one...

Chemicals that helped solve a global environmental crisis in the 1990s "” the hole in Earth's protective ozone layer "” may be making another problem "” acid rain "” worse, scientists are reporting. Their study on the chemicals that replaced the ozone-destroying chlorofluorocarbons (CFCs) once used in aerosol spray cans, air conditioners, refrigerators, and other products, appears in ACS' Journal of Physical Chemistry A, a weekly publication. Jeffrey Gaffney, Carrie J....

Study examines grasslands and grazing management impacts on global warming Grazinglands represent one of the largest land resources in the world, yet their role as net sinks or sources of greenhouse gases is essentially unknown. Previous research has emphasized the role of grazing management on the sequestration of atmospheric carbon dioxide as soil organic carbon. However, there is a lack of information regarding how grazing management impacts the flux of two potent GHGs, nitrous oxide and...

MONTREAL and VICTORIA, May 12 /PRNewswire-FirstCall/ - CN has pioneered a modal shift protocol that will create new carbon offset project opportunities for British Columbia's transportation sector, CN President and Chief Executive Officer Claude Mongeau announced today. Pacific Carbon Trust (PCT), a Crown corporation and leading provider of offsets in British Columbia (B.C.), has agreed to recognize the protocol for modal shift offset projects in B.C. The modal shift protocol allows companies...

Let a bunch of fluorine atoms get together in the molecules of a chemical compound, and they're like a heavy metal band at a chamber music festival. They tend to dominate the proceedings and not always for the better. That's particularly true where the global warming potential of the chemicals is concerned, says a new study by NASA and Purdue University researchers. The study offers at least a partial recipe that industrial chemists could use in developing alternatives with less global...

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...
