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...

Climatologists demand a differentiated discussion Glaciers of large mountain regions contribute, to some extent considerably, to the water supply of certain populated areas. However, in a recent study conducted by Innsbruck glaciologists and climatologists it has been shown that there are important regional differences. The results of the study are published in the scientific journal Proceedings of the National Academy of Sciences (PNAS). In their recently published study the glaciologists...

We all know how it feels to be low on energy after a long day. Or how it feels to be full of energy after a good night's rest or a good meal. Energy is just as important to Earth's everyday life as it is to ours. "Exploring Energy" is the theme of this year's Earth Science Week, Oct. 10-16. The American Geological Institute hosts Earth Science Week annually in cooperation with various sponsors to engage people in Earth science and encourage stewardship of Earth. NASA develops, deploys and...

The Arctic Ocean is covered by a dynamic layer of sea ice that grows each winter and shrinks each summer, reaching its yearly minimum size each fall. While the 2010 minimum remains to be seen, NASA's Aqua satellite captured this snapshot on Sept. 3. How does the Aqua satellite "see" sea ice? Microwaves. Everything on Earth's surface -- including people -- emits microwave radiation, the properties of which vary with the emitter, thereby allowing the AMSR-E microwave sensor on Aqua to map the...

Two U.S. Department of Agriculture (USDA) scientists have created new maps of Chesapeake Bay forested wetlands that are about 30 percent more accurate than existing maps. Agricultural Research Service (ARS) soil scientist Greg McCarty and USDA Forest Service ecologist Megan Lang did this by merging two remote sensing devices: an airborne LiDAR (light detection and ranging) laser sensor with an advanced "synthetic aperture radar" (SAR) satellite sensor. McCarty is at the ARS Hydrology and...

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,...

  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
