  1. Black Soot and Snow: A Warmer Combination December 22, 2003

    New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow. According to a computer simulation, black soot may be responsible for 25 percent of observed global warming over the past century.

  2. NASA Helps Forecast Reptile Distributions in Madagascar December 18, 2003

    NASA-supported biologists developed a modeling approach that uses satellite data and specimen locality data from museum collections to predict successfully the geographic distribution of 11 known chameleon species in Madagascar.

  3. NASA Satellites Watch World’s Cities Grow December 12, 2003

    Researchers used NASA’s Landsat satellite to measure and analyze urban growth among a global cross-section of 30 mid-sized cities during the 1990s, according to a two-part study presented at the Fall American Geophysical Union Meeting in San Francisco.

  4. Are Cities Changing Local And Global Climates? December 11, 2003

    New evidence from satellites, models, and ground observations reveal urban areas, with all their asphalt, buildings, and aerosols, are impacting local and possibly global climate processes. This is according to some of the world's top scientists convening in a special session at the Fall Meeting of the American Geophysical Union in San Francisco.

  5. NASA Scientist Trains Astronauts to be “Earth-Smart” December 11, 2003

    When you see one of those amazing images of the Earth from space, sand sweeping through miles of the Sahara desert, or the massive swirl of a hurricane winding up to move inland, odds are Kamlesh “Kam” Lulla had something to do with it.

  6. NASA Scientists Discover Spring Thaw Makes a Difference December 10, 2003

    Using a suite of microwave remote sensing instruments aboard satellites, scientists at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif., and the University of Montana, Missoula, have observed a recent trend of earlier thawing across the northern high latitudes.

  7. Scientists "Reconstruct" Earth's Climate Over Past Millennia December 10, 2003

    Using the perspective of the last few centuries and millennia, speakers in a press conference at the Fall Meeting of the American Geophysical Union in San Francisco will discuss the latest research involving climate reconstructions and different climate models.

  8. ICESat Captures Earth in Spectacular 3-D Images December 9, 2003

    NASA's Ice, Cloud and land Elevation Satellite (ICESat) is sending home important scientific data and spectacular 3-D views of Earth's polar ice sheets, clouds, mountains, and forestlands. The data are helping scientists understand how life on Earth is affected by changing climate.

  9. 25 Years of TOMS—2003 AGU Fall Meeting December 8, 2003

    For the last 25 years, NASA's Total Ozone Mapping Spectrometer (TOMS) instruments have been looking at ozone and making daily maps of the ozone content of the atmosphere across the globe, showing scientists the evolution of the ozone hole from 1979 to today.

  10. NASA Learning To Monitor Coral Reef Health From The Sky December 8, 2003

    Coral reef health may be accurately estimated from sensors on airplanes and satellites in the future, according to a NASA scientist who is the principal investigator in a collaborative project to develop a method to remotely sense coral health.

  11. The Measure of Water: NASA Creates New Map for the Atmosphere December 5, 2003

    NASA scientists have opened a new window for understanding atmospheric water vapor, its implications for climate change and ozone depletion.

  12. Progress, Promise in Space-Based Earthquake Research December 4, 2003

    Nearly 10 years after Los Angeles was shaken by the devastating, magnitude 6.7 Northridge earthquake, scientists at NASA and other institutions say maturing space-based technologies, new ground-based techniques and more complex computer models are rapidly advancing our understanding of earthquakes and earthquake processes.

  13. NASA Contributes to Earthquake Research December 2, 2003

    NASA’s unique contributions to this rapidly maturing field of earthquake prediction and implications of this research for mitigating future seismic hazards are the focus of a Earth Science Update, Thursday, 1 p.m. EST in NASA’s Webb Auditorium, 300 E Street S.W., Washington.
