  1. Shifts in Rice Farming Practices in China Reduce Greenhouse Gas Methane December 19, 2002

    Changes to farming practices in rice paddies in China may have led to a decrease in methane emissions, and an observed decline in the rate that methane has entered the Earth’s atmosphere over the last 20 years, a NASA-funded study finds.

  2. Launch Gives Weather Forecasters Twin Wind Watchers December 16, 2002

    Weather and climate forecasters will double their pleasure, thanks to today's successful launch of NASA’s SeaWinds scatterometer instrument.

  3. NASA Data Indicates El Niño Will Intensify and Move East December 12, 2002

    Satellite data shows that warmer than normal waters are in the central Pacific Ocean unlike the last El Nino

  4. NASA Know-How Will Reduce Automotive Emissions December 11, 2002

    NASA’s laser technology may soon be part of your car’s exhaust system.

  5. NASA Tree-Ring Study Reveals Long History of El Niño December 9, 2002

    El Niño is not a new weather phenomenon, according to a recent NASA study that looks 750 years into the past using tree-ring records.

  6. Arctic Sea Ice Shrinking, Greenland Ice Sheet Melting, According to Study December 7, 2002

    The total area of surface melt on the Greenland Ice Sheet for 2002 broke all known records for the island and the extent of Arctic sea ice reached the lowest level in the satellite record, according to scientists at the University of Colorado at Boulder.

  7. NASA’s First Gravity Mission Image Depicts a Bumpy Ride December 6, 2002

    The first image released from the Gravity Recovery and Climate Experiment (Grace), a joint NASA-German Aerospace Center mission, graphically illustrates the sensitivity of the mission’s twin spacecraft to changes in Earth’s gravity.

  8. Latest Ocean Winds Research Creates a Stir December 6, 2002

    New research findings from NASA’s Quick Scatterometer (QuikScat) satellite and its SeaWinds instrument have documented for the first time the significant effect typhoons have on the ocean and ocean life. The findings will be presented during a press conference highlighting recent research and findings from QuikScat at the fall meeting of the American Geophysical Union on Saturday, December 7, at 8 a.m. Pacific Time.

  9. NASA Research Offers Explanation for Earth’s Bulging Waistline December 6, 2002

    A team of researchers from NASA's Jet Propulsion Laboratory, Pasadena, Calif., and the Royal Observatory of Belgium has apparently solved a recently observed mystery regarding changes to the physical shape of Earth and its gravity field. The answer, they found, appears to lie in the melting of sub-polar glaciers and mass shifts in the Southern, Pacific and Indian Oceans associated with global-scale climate changes.

  10. NASA Devising Method to Remotely Monitor Ocean Environment December 6, 2002

    Low-flying airplanes could scan seas to efficiently determine coral reef health, according to a NASA scientist who will discuss her research Dec. 8 during the fall meeting of the American Geophysical Union in San Francisco.

  11. Laser Technology Helps Measure Pollution from NYC Buses December 6, 2002

    Atmospheric scientists used laser technology while riding in traffic behind New York City transit buses to find out exactly how much and what type of pollution different types of buses emit in their exhausts, and the results were surprising.

  12. Waves in the Atmosphere Batter South Pole, Shrink 2002 Ozone Hole December 6, 2002

    A greater number of large “planetary sized waves” in the atmosphere that move from the lower atmosphere into the upper atmosphere were responsible for the smaller Antarctic ozone hole this fall, according to NASA researchers.
