Beijing working to clear the air Beijing (UPI) May 2, 2008 
Chinese officials said anti-pollution efforts are helping clear the air in Beijing, with 86 days of fairly good air quality reported so far this year.
The Beijing Municipal Bureau of Environmental Protection said the number of so-called "blue sky" days is up from 67 during the same period last year, the state-run Xinhua news agency reported Friday. The Chinese news service said ... read more |

Methane Sources Over The Last 30,000 Years
Bonn, Germany (SPX) Apr 23, 2008Ice cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane ... more Changing Jet Streams May Alter Paths Of Storms And Hurricanes 
Stanford CA (SPX) Apr 22, 2008The Earth's jet streams, the high-altitude bands of fast winds that strongly influence the paths of storms and other weather systems, are shifting-possibly in response to global warming. Scientists at the Carnegie Institution determined that over a 23-year span from 1979 to 2001 the jet streams in both hemispheres have risen in altitude and shifted toward the poles. The jet stream in the ... more Viruses Keep Us Breathing 
Moffett Field CA (SPX) Apr 07, 2008Some of the oxygen we breathe today is being produced because of viruses infecting micro-organisms in the world's oceans, scientists heard Wednesday 2 April 2008 at the Society for General Microbiology's 162nd meeting held at the Edinburgh International Conference Centre. About half the world's oxygen is being produced by tiny photosynthesizing creatures called phytoplankton in the major ... more Carnegie Mellon Researchers To Curb CO2 Emissions 
Pittsburgh PA (SPX) Apr 04, 2008Carnegie Mellon University's Chris T. Hendrickson and H. Scott Matthews along with Alex Carpenter and Heather MacLean of the University of Toronto challenge Canadian officials to take the lead in eliminating dangerous carbon dioxide emissions that fuel global warming. The researchers found that farming and power generation are the largest sources of Canadian carbon dioxide emissions per ... more Scientists Identify Origin Of Hiss In Upper Atmosphere 
Los Angeles CA (SPX) Mar 06, 2008Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts - belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their spacecraft. The source of these low-frequency radio ... more |

Moffett Field CA (SPX) Nov 02, 2007Ohio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The development of an oxygen atmosphere signaled a major change in the evolution on life, and gave way for the numerous forms of oxygen-utilizing organisms we see on the Earth's surface today. Studying how and when thi ... more Researchers Find Origin Of Breathable Atmosphere Half A Billion Years Ago 
Columbus OH (SPX) Oct 30, 2007Ohio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth's crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world's oceans, spawned giant plankton blooms, and sent a burst of oxygen into ... more Study Reveals Lakes A Major Source Of Prehistoric Methane
Fairbanks AL (SPX) Oct 26, 2007A team of scientists led by a researcher at the University of Alaska Fairbanks has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age. Methane bubbling from arctic lakes could have been responsible for up to 87 percent of that methane spike, said UAF researcher Katey Walter, lead author of a report printed in the Oct. 26 is ... more Giant Atmospheric Waves Over Iowa 
Huntsville AL (SPX) Oct 12, 2007Pop quiz: define undular bore. If your answer included words such as dull or tiresome, i.e., boring, think again. Those giant waves-"undular bore waves"-were photographed Oct. 3rd flowing across the skies of Des Moines, Iowa. "Wow, that was a good one!" says atmospheric scientist Tim Coleman of the National Space Science and Technology Center (NSSTC) in Huntsville, Alabama. Coleman is an e ... more Global warming driving up humidity levels 
Paris (AFP) Oct 10, 2007Man-made global warming is driving up humidity levels, with the risk that rainfall patterns will shift or strengthen, tropical storms intensify and human health may suffer from heat stress, a study released on Wednesday said. From 1976 to 2004, when the world's average surface temperature rose 0.49 degrees Celsius (0.9 degrees Fahrenheit), global levels of atmospheric water vapour rose 2.2 p ... more |

Gakona, Alaska, June 27, 2007BAE Systems has completed work on the world's largest and most capable ionospheric research facility. The facility will be used to study interactions between high-power radio signals and the earth's ionosphere. As the prime contractor for the U.S. Defense Department's High Frequency Active Auroral Research Program (HAARP) research station, BAE Systems designed and built the facility, operating s ... more NASA Satellite Captures First View Of Night-Shining Clouds 
Greenbelt MD (SPX) Jun 29, 2007A NASA satellite has captured the first occurrence this summer of mysterious shiny polar clouds that form 50 miles above Earth's surface. The first observations of these "night-shining" clouds by a satellite named "AIM" which means Aeronomy of Ice in the Mesosphere, occurred above 70 degrees north latitude on May 25. People on the ground began seeing the clouds on June 6 over Northern Europe. AI ... more Main Component For World Latest Satellite To Measure Greenhouse Gases Delivered 
Quebec City, Canada (SPX) Jun 27, 2007ABB has announced it has delivered a spatial interferometer which is the main component on the new Japanese satellite GOSAT (Greenhouse gases Observing SATellite). The satellite, which will be launched in 2008 by the Japan Aerospace Exploration Agency (JAXA), will enable Japanese scientists to study and measure greenhouse gases in support of the Kyoto protocol made it mandatory for developed na ... more AIRS Global Map Of Carbon Dioxide From Space 
Washington DC (SPX) May 24, 2007Although originally designed to measure atmospheric water vapor and temperature profiles for weather forecasting, data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua spacecraft are now also being used by scientists to observe atmospheric carbon dioxide. Scientists from NASA; the National Oceanic and Atmospheric Administration; the European Center for Medium-Range We ... more Widespread Twilight Zone Detected Around Clouds 
Greenbelt MD (SPX) May 05, 2007There seems to be something new under the sun -- in the sky, specifically -- that could complicate scientists' efforts to get a fix on how much the world will warm in the future. Greenhouse gases are not the only things in the air that influence the temperature of our atmosphere. Clouds and small airborne particles called aerosols also play an important and complicated role. Now a new ingr ... more
