WASHINGTON, July 20 /PRNewswire-USNewswire/ -- Scientists have produced a first-of-its kind map of the height of the world's forests by combining data from three NASA satellites. The map will help scientists build an inventory of how much carbon the world's forests store and how fast that carbon cycles through ecosystems and back into the atmosphere.

A new study, involving academics at the University of Sheffield, has accurately measured for the first time the current carbon cycles in the world. The research will enable scientists to make more accurate predictions concerning the impact of climate change in the future. The paper, which will be published today (5 July 2010) in the journal Science, used large amounts of remote sensing, climate and carbon data from around the world to assess Gross Primary Production. This is the process which...

New data on photosynthesis and respiration will improve models, researchers say Two recent international studies are poised to change the way scientists view the crucial relationship between Earth's climate and the carbon cycle. These reports explore the global photosynthesis and respiration rates"”the planet's deep "breaths" of carbon dioxide, in and out"”and researchers say that the new findings will be used to update and improve upon traditional models that couple together...

With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution? A new study by scientists at the Carnegie Institution suggests that while removing excess carbon dioxide would cool the planet, complexities of the carbon cycle would limit the effectiveness of a one-time effort. To keep carbon dioxide at low levels would require a...

A NASA-led research team has expanded the growing global armada of remote sensing satellites capable of studying carbon dioxide, the leading greenhouse gas driving changes in Earth's climate. The newest addition is the Tropospheric Emission Spectrometer (TES) instrument on NASA's Aura spacecraft, launched in 2004. TES measures the state and composition of Earth's troposphere, the lowest layer of Earth's atmosphere, located between Earth's surface and about 16 kilometers (10 miles) in...

Numerous studies are documenting the growing effects of climate change, carbon dioxide, pollution and other human-related phenomena on the world's oceans. But most of those have studied single, isolated sources of pollution and other influences. Now, a marine geochemist at the Woods Hole Oceanographic Institution (WHOI) has published a report in the latest issue of the journal Science that evaluates the total impact of such factors on the ocean and considers what the future might hold. "What...

Scientists review the benefits and tradeoffs of current methods in forest carbon storage While the U.S. and other world leaders consider options for offsetting carbon emissions, it is important to take into account the role forests play in the global carbon cycle, say scientists in a paper published in the spring edition of Issues in Ecology. Currently, the carbon stored in forests and harvested wood products offsets 12-19 percent of U.S. fossil fuel emissions"”growth primarily the...

Potential climate change caused by rising levels of carbon dioxide might be better understood by examining fossil plant remains from millions of years ago, according to biogeochemists. The types of carbon within the leaves can serve as a window into past temperatures and environmental conditions. "Carbon isotopes are really important for understanding the carbon cycle of the past, and we care about the carbon cycle of the past because it gives us clues about future climate change," said Aaron...

For insight into what can happen when the Earth's carbon cycle is altered -- a cause and consequence of climate change -- scientists can look to an event that occurred some 720 million years ago. New data from a Princeton University-led team of geologists suggest that an episode called "snowball Earth," which may have covered the continents and oceans in a thick sheet of ice, produced a dramatic change in the carbon cycle. This change in the carbon cycle, in turn, may have triggered future...

New Haven, Conn. -- The physiology of microbes living underground could determine the amount of carbon dioxide emitted from soils on a warmer Earth, according to a study published online this week in Nature Geoscience. Researchers at UC Irvine, Colorado State University and the Yale School of Forestry & Environmental Studies have found that as global temperatures increase, microbes in soil become less efficient over time in converting carbon in soil into carbon dioxide, which is a key...
