Black Soot and Snow: A Warmer Combination
December 22 — 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. More

NASA Helps Forecast Reptile Distributions in Madagascar
December 18 — 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. More

NASA Satellites Watch World’s Cities Grow
December 12 — 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. More

Are Cities Changing Local And Global Climates?
December 11 — 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. More

NASA Scientist Trains Astronauts to be “Earth-Smart”
December 11 — 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. More

NASA Scientists Discover Spring Thaw Makes a Difference
December 10 — 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. More

Scientists "Reconstruct" Earth's Climate Over Past Millennia
December 10 — 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. More

ICESat Captures Earth in Spectacular 3-D Images
December 9 — 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. More

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

NASA Learning To Monitor Coral Reef Health From The Sky
December 8 — 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. More

The Measure of Water: NASA Creates New Map for the Atmosphere
December 5 — NASA scientists have opened a new window for understanding atmospheric water vapor, its implications for climate change and ozone depletion. More

Progress, Promise in Space-Based Earthquake Research
December 4 — 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. More

NASA Contributes to Earthquake Research
December 2 — 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. More
