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.
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.
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.
In an effort to create the world's best topographic map, NASA displayed spectacular new 3-D images and animations of California from space.
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.
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.
NASA unveiled a new Web site today in which it publishes satellite images in near real time over natural hazards around the world.
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.
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.
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.
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.
A space-based survey offers new insights into the history of central California's varied topography and the region's earthquake hazards.
