According to NASA-funded researchers, developed land in the greater Washington-Baltimore metropolitan area is projected to increase 80 percent by 2030.

While climate may be impacted by carbon dioxide emissions, aerosols and other factors, a new study offers further evidence land surface changes may also play a significant role.

NASA scientists have an explanation for one of the worst climatic events in the history of the United States, the "Dust Bowl" drought, which devastated the Great Plains and all but dried up an already depressed American economy in the 1930s.

A NASA-funded study found some climate models might be overestimating the amount of water vapor entering the atmosphere as the Earth warms.

Using satellite and other data, scientists have discovered that sea surface temperatures and sea level pressure in the North Pacific have undergone unusual changes over the last five years.

Using data from the Aqua satellite, NASA scientists found that heavy smoke from burning of vegetation across Amazonia inhibits cloud formation, suggesting that the cooling of global climate by pollutant particles, called aerosols, may be smaller than previously estimated.

An international team of scientists from NASA and other research institutions embarked on a three-week expedition of discovery that will take them from the lush, dense rain forests of Central America to the frigid isolation of Antarctica.

Students, scientists, teachers, reporters and the scientifically curious can locate any kind of Earth science data much easier and quicker than ever before, using NASA's Global Change Master Directory (GCMD).

March 1, 2004, marks the 20th anniversary of operations of the NASA/USGS 'workhorse' satellite, Landsat 5.
