Fewer Clouds Found In Tropics: NASA scientists discover new evidence of climate change
January 31 — After examining 22 years of satellite measurements, NASA researchers find that more sunlight entered the tropics and more heat escaped to space in the 1990s than in the 1980s. Their findings indicate less cloud cover blocked incoming radiation and trapped outgoing heat. More

New Satellite Maps Reveal Where in the World Lightning Strikes
January 28 — Lightning. It avoids the ocean, but likes Florida. It's likely to strike in the Himalayas and even more so in central Africa. And lightning almost never strikes the North or South Poles. More

U.S. Ecology Dramatically Altered by Fertilizers and Acid Rain
January 24 — A NASA-funded study of ancient and unpolluted South American forests promises to upend longstanding beliefs about ecosystems and the effects of pollution in the Northern Hemisphere. More

Pictures from the Real Edge: NASA Posts U.S. Topography Data
January 22 — In an effort to create the world's best topographic map, NASA displayed spectacular new 3-D images and animations of California from space. More

Study Links El Niño To Deadly South American Disease
January 17 — In a groundbreaking collaborative study, NASA climatologists and U.S. military health specialists may have discovered a way to predict outbreaks of a deadly South American disease by observing sea surface temperature. More

Climate Change May Bring More Winter Floods, and a Drier Growing Season in California
January 17 — A new study finds that climate warming over the next century will bring potential flooding in winter, as a result of increased streamflow throughout California. The study also finds less water would be available during the summer months. More

NASA Unveils New 'Natural Hazards' Web Site
January 16 — NASA unveiled a new Web site today in which it publishes satellite images in near real time over natural hazards around the world. More

NASA Satellite Instrument Warms Up Global Cooling Theory
January 16 — Measurements from a NASA Langley Research Center satellite instrument dispute a recent theory that proposes that clouds in the Tropics might cool the Earth and counteract predictions of global warming. More

New Method Greatly Improves U.S. Seasonal Forecasts
January 15 — A new technique could raise the bar for predicting seasonal precipitation by 10 to 20 percent for all seasons in the United States, a NASA-funded study finds. More

SeaWinds Casts a Closer Eye on Tropical Cyclones
January 14 — In a new NASA-funded study, researchers have dramatically improved the warning time for tropical cyclone development in the Atlantic and Eastern Pacific hurricane basins using satellite data to access a combination of the spin of the atmosphere and wind speed data. With this new method, potential tropical cyclones can be detected more than 40 hours earlier than with traditional methods, giving more time for warnings and preparation. More

Greenhouse Emissions Growth Slowed Over Past Decade
January 14 — A new NASA-funded study shows that the rate of growth of greenhouse gas emissions has slowed since its peak in 1980, due in part to international cooperation that led to reduced chlorofluorocarbon use, slower growth of methane, and a steady rate of carbon dioxide emissions. More

Space Survey Yields New Info on California's Landscape, Quakes
January 11 — A space-based survey offers new insights into the history of central California's varied topography and the region's earthquake hazards. More
