NASA and the National Imagery and Mapping Agency generated a brand new look and understanding of the place we call home through a complete global topographic data set.

The tides appear to be responsible for the pattern of motion exhibited by ice streams in the Antarctic, according to a team of geologists from NASA, Penn State and University of Newcastle, Newcastle Upon Tyne, England.

A study of Santa Cruz, Bolivia, which used NASA satellites and computer models, reports that cutting down tropical forests and converting grasslands to crops may inadvertently warm those local areas.

Scientists using data from a NASA satellite have found another piece in the global climate puzzle created by El Niño, which produce a steady rain in the middle of the Pacific Ocean.

Water released from Lake Vostok, deep beneath the south polar ice sheet, could gush like a popped can of soda if not contained, opening the lake to possible contamination and posing a potential health hazard to NASA and university researchers.

Scientists added ozone measurements from a NASA satellite into computer weather forecast models and improved several factors in a forecast of a major winter snowstorm that hit the United States in 2000.

Predicting drought, floods, rain or snow, especially months in advance is tricky. But NASA scientists at the National Space Science and Technology Center in Huntsville, Ala., are working to take the guesswork out of long-term prediction.

What happens in the stratosphere, the atmospheric layer just above where commercial airplanes fly, may have a larger influence on our climate and weather than previously thought, according to research funded by NASA, the National Oceanic and Atmospheric Administration (NOAA), and the National Science Foundation.
