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...

WASHINGTON, Jan. 29 /PRNewswire-USNewswire/ -- NASA's first spacecraft dedicated to studying atmospheric carbon dioxide is in final preparations for a Feb. 23 launch from Vandenberg Air Force Base in California. Carbon dioxide is the leading human-produced greenhouse gas driving changes in Earth's climate.

NASA's first spacecraft dedicated to studying atmospheric carbon dioxide is in final preparations for a Feb. 23 launch from Vandenberg Air Force Base in California. Carbon dioxide is the leading human-produced greenhouse gas driving changes in Earth's climate. The Orbiting Carbon Observatory will provide the first complete picture of human and natural carbon dioxide sources as well as their "sinks," the places where carbon dioxide is pulled out of the atmosphere and stored. It will map 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...

A scientist with the World Agroforestry Center called for new grazing practices among farmers as an effective way to fight global climate change while improving farm productivity. Andreas Wilkes told Reuters that simple changes could help soak up millions of tons of carbon each year, adding that they should be adopted by the United Nations as part of a way for farmers to earn carbon credits as incentives to pay for a needed change in practices. Wilkes said new methods, including replanting...

Canada's 1.2 million square miles of forests have turned from being carbon-absorbing aids to the environment to carbon-emitting liabilities, scientists say. Since 1999, and especially in the last five years, the forests have shifted from being a carbon sink to a carbon source, Werner Kurz, senior research scientist at the Canadian Forest Service in Vancouver, told a Chicago Tribune correspondent. Rising global temperatures are drying out forests making them more susceptible to fires, which...

The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.In recent years, there has been growing evidence for the hypothesis that the effect of the pandemics in the Americas wasn't confined to killing indigenous peoples. Global climate appears to have been altered as well.Stanford...

Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. These early conservationists disappeared 500 years ago, but centuries later, their soil is still rich in organic matter and nutrients. Now, scientists, environmental groups and policymakers forging the next world climate agreement see biochar not only as an important tool for replenishing soils, but as a...

NASA said it is preparing to launch a satellite that will be capable of spotting the source of carbon emissions. The Orbiting Carbon Observatory (OCO) will give scientists a better understanding of the location of CO2 emissions and absorption. "This is NASA's first spacecraft specifically dedicated to mapping carbon dioxide," said principal investigator David Crisp, who provided more details about the "ËœCO2 Hunter' during the American Geophysical Union's (AGU) Fall Meeting this...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
