WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

Five days after the Twin Towers collapsed, two geoscientists boarded a plane from Denver to New York City. They were part of a team that would use remote sensing techniques to categorize the hazards that might affect the rescue workers, civilians and survivors of the terrorist attacks. One of their immediate tasks involved identifying long-burning fires under the rubble. A second was to create a compositional profile of the debris cloud that resulted from the devastation. Part of the project...

Rising air temperatures in the Arctic region have led to an increase in rainfall and a decrease in snowfall, making the sea ice more susceptible to melting, a new study has revealed. The research was presented today by Dr James Screen from the University of Melbourne at the XXV International Union of Geodesy and Geophysics General Assembly in Melbourne. The Arctic region is warming more rapidly than anywhere else on Earth. Dr Screen of the University's School of Earth Sciences, who led the...

The world's largest database on plants' functional properties, or traits, has been pub-lished. Scientists compiled three million traits for 69,000 out of the world's ~300,000 plant species. The achievement rests on a worldwide collaboration of scientists from 106 re-search institutions. The initiative, known as TRY, is hosted at the Max Planck Institute for Biogeochemistry in Jena (Germany). Jointly coordinated with the University of Leipzig (Germany), IMBIV-CONICET (Argentina), Macquarie...

Up to two-thirds of Earth's permafrost likely will disappear by 2200 as a result of warming temperatures, unleashing vast quantities of carbon into the atmosphere, says a new study by the University of Colorado Boulder's Cooperative Institute for Research in Environmental Sciences. The carbon resides in permanently frozen ground that is beginning to thaw in high latitudes from warming temperatures, which will impact not only the climate but also international strategies to reduce fossil fuel...

A coupled-cycles framework is essential to balancing human needs with the health of the planet If society wants to address big picture environmental problems, like global climate change, acid rain, and coastal dead zones, we need to pay closer attention to the Earth's coupled biogeochemical cycles. So reports a special issue of Frontiers in Ecology and the Environment, published this month by the Ecological Society of America. "There are nearly seven billion people on the planet. And our...

A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate. The findings are important, researchers say, because they suggest that Arctic warming amplified by the loss of reflectivity could be even more significant than previously thought. The study was published online this week in Nature Geoscience. It was funded...

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...
