Near infrared (NIR) light includes wavelengths between 700 and 1,100 nanometers. Water absorbs NIR, so these wavelengths are useful for discerning land-water boundaries that are not obvious in visible ...

The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. This ...

The impact of increased surface temperatures is significant in itself. But global warming will have additional, far-reaching effects on the planet. Warming modifies rainfall patterns, amplifies ...

All matter in the universe that has a temperature above absolute zero (the temperature at which all atomic or molecular motion stops) radiates energy across a range of wavelengths in the ...

The Intergovernmental Panel on Climate Change stated in their most recent report that global surface temperature at the end of this century will probably be between 1.8 and 4 degrees Celsius warmer ...

Agencies and scientists across the globe continue to use Landsat data to monitor deforestation and to enforce environmental policies. For example, in 2003, the state of Mato Grosso, Brazil, piloted a ...

Nanga Parbat is the ninth tallest mountain in the world, but it is one of the most alluring for both mountain climbers and scientists. Located in northern Pakistan, Nanga Parbat is the westernmost of ...

Science suggests that to mitigate the human contribution to global warming, we should reduce carbon dioxide and other greenhouse gas emissions. Because some additional warming is inevitable—even if we ...

Welcome, teachers, to Mission: Biomes! This site was designed for teachers to use in classrooms as a supplementary, interdisciplinary unit. Mission: Biomes is especially appropriate for grades 3 ...

All the members of our team are now in Kulusuk, Greenland. We’re quite isolated in this tiny village but we have a whole team behind us, making sure we get our stuff on time. The people in town are ...

Although there was little in the way of published research on estimating U.S. lawn area, the research group Milesi was studying and working with at the University of Montana had a lot of experience ...

The creosote bush (Larrea tridentata) is a medium-sized evergreen shrub. It has small pointed green leaves with a waxy coating. These leaves have adapted to conserve water and survive high ...
