Ithaca - Nov 20, 2003A train has derailed at the edge of a city, spreading toxic chemicals and fumes over a wide area. Before rescue and decontamination workers can enter the danger zone, they need more information: How widespread is the contamination? Where are the hotspots? Where and how are toxic gases moving? NOAA Reports Methane Levels Stablizing 
WASHINGTON - Nov 19, 2003One of the atmosphere's most potent greenhouse gases, methane, may now have leveled off, according to a study by NOAA researchers and National Institute for Space Research in the Netherlands. Scientists aren't sure yet if this "leveling off" is just a temporary pause in two centuries of increase or a new state of equilibrium. |

A Mostly Quiet Pacific 
Pasadena - Nov 19, 2003 Some climate forecast models indicate there is an above average chance that there could be a weak to borderline El Ni�o by the end of November 2003. However, the trade winds, blowing from east to west across the equatorial Pacific Ocean, remain strong. Uncovering Mysteries Beneath The Earth's Surface 
Boston - Nov 19, 2003Back in the old days, when doctors looked for tumors, exploratory surgery was the only option. Today they use CAT scans, x-rays, ultrasound, and other non-intrusive methods for checking out what lies beneath the skin's surface. But how do we determine what is beneath the Earth's surface? Invasive surgery on the Earth is just as dated as doctors' old methods of finding tumors, if you ask Eric Miller, associate professor of electrical and computer engineering at Northeastern University. NOAA Awards Harris Study For GOES-R Ground Segment 
Melbourne - Nov 18, 2003Harris Corporation has been awarded a one- year study contract by the National Oceanic and Atmospheric Administration (NOAA) for ground segment work supporting the advanced Geostationary Operational Environmental Satellite-R (GOES-R) program. Scheduled to launch in 2012, GOES-R will feature highly advanced sensor technology and will provide much higher resolution and data frequency than the current GOES spacecraft family. Russia Conducts Widespread Atmospheric Temperature Study
St. Petersburg - Nov 18, 2003A group of researchers guided by Academician Kondratyev has analyzed the archives of temperatures in the Northern Arctic area since 1959 through 2000. Having done this analysis, the researchers stated that constant thermal energy redistribution took place in high latitudes, therefore the state of atmosphere in general had not changed. Iceberg's End Caught By Envisat 
Paris (ESA) Nov 11, 2003ESA's Envisat satellite was witness to the dramatic last days of what was once the world's largest iceberg, as a violent Antarctic storm cracked a 160-km-long floe in two. Arctic And Antarctic Sea Ice Marching To Different Drivers 
Greenbelt - Nov 11, 2003A 30-year satellite record of sea ice in the two polar regions reveals that while the Northern Hemisphere Arctic ice has melted, Southern Hemisphere Antarctic ice has actually increased in more recent years. However, due to dramatic losses of Antarctic sea ice between 1973 and 1977, sea ice in both hemispheres has shrunk on average when examined over the 30-year time frame. Yucca Mountain Site Must Make Use Of Geological Safety Net 
Bloomington - Nov 11, 2003A proposed federal repository near Yucca Mountain, Nev., for the long-term storage of 70,000 metric tons of high-level radioactive waste must take advantage of the mountain's natural geological properties, according to a new study by scientists at Indiana University Bloomington and Los Alamos National Laboratory. |
The Suffocating Age
Seattle - Nov 10, 2003 Recent evidence suggests that oxygen levels were suppressed worldwide 175 million to 275 million years ago and fell to precipitously low levels compared with today's atmosphere, low enough to make breathing the air at sea level feel like respiration at high altitude. Ice Cores May Yield Clues To 5,000-Year-Old Mystery 
Columbus - Nov 10, 2003The latest expeditions to ice caps in the high, tropical Peruvian Andes Mountains by Ohio State University scientists may shed light on a mysterious global climate change they believe occurred more than 5,000 years ago. Mass Extinctions May Promote Longevity Of New Species 
Cincinnati - Nov 10, 2003With the economy, we talk about cycles of boom and bust. Make that "bust and boom" when it comes to the geological record in the post-Paleozoic world, University of Cincinnati geologist Arnold Miller suggests, after his analysis of marine fossil genera and what happens after mass extinction events. Vast Nitrogen Reserves Hidden Beneath Desert Soils 
Los Alamos - Nov 07, 2003A University of California scientist working at Los Alamos National Laboratory in collaboration with researchers from the U.S. Geological Survey, New Mexico Institute of Mining and Technology, the University of Nevada, the University of Arkansas and Desert Research Institute in Reno, Nev., has recently found evidence that there may be significantly more amounts of nitrogen, in the form of nitrates, than previously estimated in desert landscapes. More Snow for Great Lakes Region 
Hamilton - Nov 06, 2003Climate change in the past century has had a surprising impact on the Great Lakes region of the U.S. - more snow. A comparative study of snowfall records in and outside of the Great Lakes region indicated a significant increase in snowfall in the Great Lakes region since the 1930s but no such increase in non-Great Lakes areas. Little Islands Cut A Big Wake Across Pacific Climate 
Greenbelt - Nov 05, 2003On a map of the world, the Hawaiian Islands are barely a speck in the 64 million square miles of the Pacific Ocean. But oceanographers recently discovered that these tiny dots on the map have a surprising effect on ocean currents and circulation patterns over much of the Pacific. Exploring The Unknown World Of "Cloud Nine" 
Boulder - Jul 08, 2002CORRECT URL climate-02w.html Ball Aerospace has won a contract to build a NASA spacecraft that will explore the little understood 100 kilometers above the arctic in the mesosphere where polar clouds form and drift southward.Selected as part of NASA's Small Explorer (SMEX) program the mission will increase our understanding of what surely must be "cloud nine" at the edge of space. |
