As the concentration of heat-trapping carbon dioxide in Earth's atmosphere continues to rise, so also does public awareness, as well as efforts to find solutions to this global problem. Increasing concentrations of this potent greenhouse gas threaten to alter Earth's climate in ways that will have profound impacts on the welfare and productivity of society and Earth's ecosystems. This year marks the 50th anniversary of Scripps Institution of Oceanography scientist Charles David...

For the first time, farmers have data that tracks at the county level on-site and off-site energy use and carbon dioxide emissions associated with growing crops in the United States. This information is vital for examining changes in cropland production and management techniques and could play an even bigger role as more land is devoted to bioenergy crops, said Oak Ridge National Laboratory's Tristram West, lead author of a paper published on line in the Journal of Environmental Quality. "By...

An experiment to study the effects of naturally deposited iron in the Southern Ocean has filled in a key piece of the puzzle surrounding iron's role in locking atmospheric carbon dioxide (CO2) in the ocean. The research, conducted by an international team led by Raymond Pollard of the National Oceanography Centre, Southampton, and included Matthew Charette, a marine chemist at the Woods Hole Oceanographic Institution (WHOI), found that natural iron fertilization enhanced the export of carbon...

More than 200 scientists from around the world have attended the weeklong POLinSAR 2009 workshop hosted at ESRIN, ESA's Earth Observation centre in Frascati, Italy. Discussions among the participants include new techniques for providing vital information on our planet that could help to combat global warming through carbon accounting, wetland preservation and improve climate models. Using the novel polarimetric mode of the PALSAR synthetic aperture radar (SAR) aboard Japan's ALOS satellite,...

Making bales with 30 percent of global crop residues "“ the stalks and such left after harvesting "“ and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. That is a significant amount of carbon, the process can be accomplished with existing technology and it can be done year after year, according to Stuart Strand, a University of Washington research...

New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration. U.S. Forest Service and Carnegie Institution scientists involved in the research published their findings this month in the journal Ecosystems and hope it will help other researchers racing to assess threats to tropical forests around the world. "Our results clearly show the...

Picture a tree in the forest. The tree "inhales" carbon dioxide from the atmosphere, transforming that greenhouse gas into the building materials and energy it needs to grow its branches and leaves. By removing carbon dioxide from the atmosphere, the tree serves as an indispensable "sink," or warehouse, for carbon that, in tandem with Earth's other trees, plants and the ocean, helps reduce rising levels of carbon dioxide in the air that contribute to global warming. Each year, humans release...

Mercury levels in soil increase as carbon dioxide levels rise, suggesting such pollution will increase with global warming, a U.S. university researcher said. Carbon dioxide-enriched soil contained almost 30 percent more mercury than regular soil, evidently because the soil had a greater capacity to trap and hold onto mercury, botany postdoctoral associate Sue Natali of the University of Florida said in the journal Oecologia. Carbon dioxide, the main greenhouse gas, has increased nearly 40...
