Cardiff - Sep 11, 2003New evidence supports volcanic eruption theory The extinction of the dinosaurs � thought to be caused by an asteroid impact some 65 million years ago � was more likely to have been caused by a 'mantle plume' � a huge volcanic eruption from deep within the earth's mantle, the region between the crust and the core of the earth. This theory, already supported by a significant body of geologists and palaeontologists, is strengthened by new evidence to be presented at an international conference at Cardiff University on 11-12 September. |

NASA Releases Near-Earth Object Search Report
Pasadena - Sep 11, 2003NASA has released a technical report on potential future search efforts for near-Earth objects after a year of analysis by scientists working on this issue. This Science Definition Team was chartered to study what should be done to find near-Earth objects less than 1 kilometer in size. MIT Reassess Asteroid Hazards 
Monterey - Sep 11, 2003Of the approximately 1,000 near-Earth asteroids larger than 1 kilometer in diameter, one strikes the Earth on average once every 600,000 years, MIT Lincoln Laboratory researcher J. Scott Stuart reported today (Sept. 5) at the 35th annual meeting of the American Astronomical Society Division for Planetary Sciences. Undergrads Ready For Launch 
Wallops Island - Sep 10, 2003After two years of planning and preparation, undergraduate students from the University of Virginia, Charlottesville, are ready for the launch of their experiments aboard a NASA rocket in the early morning on Sept 16. Ocean May Sponge Up Some Warmth Over Next 50 Years 
Greenbelt - Sep 04, 2003NASA's improved global climate computer model, which simulates and projects how the Earth's climate may change, indicates that the oceans have been absorbing heat since 1951 and will continue to absorb more heat from the atmosphere over the next 50 years. Asteroid 2003 QQ47's Potential Earth Impact in 2014 Ruled Out
Pasadena - Sep 03, 2003Newly discovered asteroid 2003 QQ47 has received considerable media attention over the last few days because it had a small chance of colliding with the Earth in the year 2014 and was rated a "1" on the Torino impact hazard scale, which goes from 0 to 10. Americans Most Misinformed About Global Warming 
Champaign - Sep 03, 2003Despite huge differences in all kinds of resources, citizens of poorer developing countries have essentially the same level of knowledge about the sources of global warming as citizens of richer developed countries -- and that level isn't very high. As Sea Level Rises, Beaches Shrink 
Pasadena - Sep 01, 2003Stack two dimes on top of each other. Their height is a tiny fraction less than global sea level is rising each year. The increase looks small, but the consequences are potentially huge. Rising sea level threatens to inundate low-lying regions, such as the Chesapeake, and dramatically increase coastal and beach erosion around the world. The Fate Of Toxic Pollutants Harbored In Arctic Waters 
New York - Sep 12, 2003An analysis of pesticides that accumulate in Arctic waterways is giving scientists insight into the fate of such pollutants once they settle in polar regions. |
Modern Global Warming More Damaging Than In The Past
Ann Arbor - Sep 01, 2003Global warming isn't what it used to be. "Some people will tell you that the planet has warmed in the past and that species always managed to adapt, so there's no cause for alarm. Unfortunately that's not the case," said Johannes Foufopoulos, assistant professor at the University of Michigan School of Natural Resources and Environment. Weather Extremes Shed Light On Prairie's Past Future 
Champaign - Sep 01, 2003Highway travelers view much of the Midwest as little more than barren flatlands. The formation of the region and its rich soils, especially tall grass areas that seemingly should support diverse forests, however, have long fascinated scientists. Methane Thought To Be Responsible For Mass Extinction 
Evanston - Sep 01, 2003What caused the worst mass extinction in Earth's history 251 million years ago? An asteroid or comet colliding with Earth? A greenhouse effect? Volcanic eruptions in Siberia? Or an entirely different culprit? A Northwestern University chemical engineer believes the culprit may be an enormous explosion of methane (natural gas) erupting from the ocean depths. Unexpected Discovery About Core 
Stockholm - Sep 01, 2003The core of the earth doesn't look the way it was expected to. Scientists at the Royal Institute of Technology in Stockholm, Sweden, KTH, can now show that iron, under extremely high pressure, such as that found in the inner earth, takes on unexpected properties, and this can be of importance in understanding the movements of the earth, such as, earthquakes. The results are being presented in the new issue of the British scientific journal Nature. Atmospheric Bromine, Which Attacks Ozone Layer, Is Decreasing 
Washington - Sep 01, 2003Researchers have discovered that total bromine in the lower atmosphere has been decreasing since 1998 and is now more than five percent below the peak reached that year. Bromine is one of the most active destroyers of the stratospheric ozone layer, which forms an invisible shield around the Earth, protecting it from the biologically damaging ultraviolet rays of the Sun. Cropslands Push Up Average Tropical Temperatures 
Greenbelt - Aug 26, 2003While croplands may provide more food than forests, they don�t offer much relief from hot tropical climes, a new study finds. z Researchers Measure Atmospheric Isotope Buildup 
Los Alamos - Aug 26, 2003Researchers at Los Alamos National Laboratory have shown that deuterium, a naturally occurring stable isotope of hydrogen, concentrates itself in molecular hydrogen (H2) in a key layer of the atmosphere. The finding lends important insight into the natural cycle of molecular hydrogen and could have ramifications for the use of fuel cells as an alternative energy source. |
