A new study found that cattle grazed on the grasslands of China actually helps reduce the greenhouse gas nitrous oxide. Environmentalists have been urging people for years to stop eating meat because the of methane produced by cattle. According to the Telegrpah, the researchers said this does not mean that producing livestock to eat is good for the environment in all countries.  However, it can be better for global warming to let animals graze on grassland in certain circumstances....

An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest "carbon sinks" become net carbon generators instead. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist Erik Hamerlynck teamed up with Rutgers University biologist Karina Schafer and U.S. Forest Service colleagues Kenneth...

Relatives of ingredients in hair-conditioning shampoos and fabric softeners show promise as a long-sought material to fight global warming by "scrubbing" carbon dioxide (CO2) out of the flue gases from coal-burning electric power generating stations, scientists reported March 24 at the 239th National Meeting of the American Chemical Society (ACS). Their report, the first on use of these so-called aminosilicones in carbon dioxide capture, concluded that the material has the potential to remove...

As oxygen-deprived waters increase, they emit more greenhouse gasses into atmosphere The increased frequency and intensity of oxygen-deprived "dead zones" along the world's coasts can negatively impact environmental conditions in far more than just local waters. In the March 12 edition of the journal Science, University of Maryland Center for Environmental Science oceanographer Dr. Lou Codispoti explains that the increased amount of nitrous oxide (N2O) produced in low-oxygen (hypoxic) waters...

A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there "“ or could be created "“ to accomplish the task. University of Michigan biological chemist Steve Ragsdale, along with research assistant Elizabeth Pierce and scientists led by Fraser Armstrong from the University of Oxford in the U.K., have figured out a way to efficiently turn carbon dioxide into...

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....

Scientists in Texas are reporting that a technique used in the search for new drugs could also be used in the quest to discover new, environmentally friendly materials for fighting global warming. Such materials could be used to capture the greenhouse gas carbon dioxide from industrial smokestacks and other fixed sources before it enters the biosphere. The new study appears in ACS' bi-monthly journal Energy & Fuels. Michael Drummond and colleagues Angela Wilson and Tom Cundari note that...

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...
