Scientists believe that Florida's very active 2004 hurricane season may have played an important part in the development of extensive and long-lasting red tide conditions that affected its coastal areas in 2005.

Scientists from NASA, the National Oceanic and Atmospheric Administration, universities and international agencies are involved in a field research campaign to study how winds and dust conditions from Africa influence the birth of hurricanes in the Atlantic Ocean.

A first-of-its-kind survey of how well the world's coral reefs are being protected was made possible by a unique collection of NASA views from space.

A study using NASA satellite data and weather records show the urban heat island effect, pollution, irrigation and population changes alter rainfall in desert cities.

The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation spacecraft known as CALIPSO is returning never-before-seen images of clouds and aerosols, tiny particles suspended in the air.

NASA scientists have determined the formation of clouds is affected by the lightness or darkness of air pollution particles. This also impacts Earth's climate.

For the first time, NASA scientists using space-based measurements have directly monitored and measured the complete cycle of water movement for an entire continent.
