Warming could free far more carbon from high Arctic soil than earlier thought
(12/05/2005) Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. A three-year study of soils in northwest Greenland found that a key previous study greatly underestimated the organic carbon stored in the soil. That's because the earlier work generally looked only at the top 10 inches of soil, said Jennifer Horwath, a UW doctoral student in Earth and space sciences.
Soil moisture, root depth influence climate models
(12/05/2005) By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics.
Somali pirates force UN food aid to take land route
(12/05/2005) Facing a plague of piracy off the Horn of Africa that has closed its usual supply lines by sea, the United Nations World Food programme (WFP) today announced the arrival in southern Somalia of its first overland truck convoy carrying food aid in almost five years, and called for urgent funding to make up for the increased costs.

70 years after logging, forests don't hold as much carbon as original forests
(12/05/2005) New research out of Ohio State University suggests that following logging, temperate forests take long periods of time to recover their carbon storing capacity. The scientists examined forests of of the upper Great Lakes region, which were 90% logged at the turn of the century, and found that they store only half the carbon the original forests contained. Poor forest management is blamed for the shortfall.

Amazon rainforest biodiversity due to biology not climate change says study
(12/05/2005) The biodiversity of the Amazon rainforest results from biological factors, not climate change as widely thought, says new research published in the journal Proceedings of the Royal Society B. Scientists have long argued that the species richness of tropical forests could be due to climate change-induced fragmentation, known as the "forest refuge: theory, and other external factors that caused geographic isolation. Now, researchers from University College London say that biological influences play a greater role in driving species evolution.
Congo rainforest - 600,000 sq km slated for logging

Companies increasingly at risk for climate change litigation says UN
(12/05/2005) Companies which contribute to climate change will increasingly face legal action according to a U.N.-sponsored report accounced last week but scheduled for released in March 2006. London-based law firm Freshfields is working with Dutch bank ABN Amro to produce the U.N. report which aims to encourage investors to address environmental, social and governance issues in their investment decisions.
Temperate forests may worsen global warming, tropical forests fight higher temperatures
(12/05/2005) Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. But they also absorb sunlight, warming the air in the process. According to a new study from the Carnegie Institution's Department of Global Ecology and Lawrence Livermore National Laboratory, planting forests at certain latitudes could make the Earth warmer.

Last year the figure was 10,088 square miles (26,129 sq km kilometers) and since 1978 some 206,250 square miles (534,200 sq km) of forest has been lost.
Energy efficiency helped California grow an extra $31 billion finds study
(12/04/2005) Countering Bush administration claims to the contrary, environmental officials for the state of California and the Brazilian state of Sao Paulo have found significant evidence that greenhouse gas pollution can be substantially reduced at a profit rather than a cost. The study, commissioned by the William and Flora Hewlett Foundation, found that energy efficiency has helped the California economy grow an extra 3 percent - a $31 billion gain - compared to business as usual. Further, the researchers say that each Californian typically saved about $1,000 per year between 1975 and 1995 just through efficiency standards for buildings and appliances.

U.S. "exporting" carbon emissions to China says study
(12/01/2005) The growth of Chinese imports in the U.S. economy boosted the total emissions of carbon dioxide (a primary greenhouse gas) from the two countries by over 700 million metric tons between 1997 and 2003, according to a study published online in the journal Energy Policy. The analysis, prepared by two scientists at the National Center for Atmospheric Research, suggests that American emissions of carbon dioxide in 2003 would have been 6% higher if the United States had manufactured the products that it imported from China. Meanwhile, China's 2003 emissions would have been 14% lower had it not produced goods for the United States.

Study uncovers how thousands of tree species coexist in rain forest
(11/30/2005) A group of scientists have a developed a new theory to explain why the biodiversity of tropical rain forests is so high and how species are assembled in an ecological community. According to their research presented in Nature, the answer can be found in 'neutral theory' whereby community membership is determined by just five fundamental processes. The scientists say that species will regulate themselves to make room for each other if they follow the 'membership rules.' The new theory undermines the conventional 'niche theory' which has been traditionally used to explain community assemblages.

The startling and controversial prediction, made last year in a report commissioned by the World Worldwide Fund for Nature (WWF) and the Queensland government, is just one of the dire scenarios forecast for reefs in the near future. The degradation and possible disappearance of these ecosystems would have profound socioeconomic ramifications as well as ecological impacts says Ove Hoegh-Guldberg, head of the University of Queensland's Centre for Marine Studies.
Genetic defenders protect crops from fungal disease
(11/17/2005) Like waves of soldiers guarding a castle gate, multiple genetic defenders cooperate to protect plant cells against powdery mildew disease, according to a new study. Powdery mildew is a common fungal infection in plants that attacks more than 9,000 species, including many crops such as barley and wheat, and horticultural plants such as roses and cucumbers. The researchers, including Shauna Somerville and Monica Stein of the Carnegie Institution's Department of Plant Biology, are the first to document how these defense genes team up in plants. The discovery could help combat fungal parasites that devastate crops and cost growers billions of dollars in pesticides every year.
Global warming will reduce glaciers, water supply and affect millions of people
(11/16/2005) In the looming future, global warming will reduce glaciers and storage packs of snow in regions around the world, causing water shortages and other problems that will impact millions of people. That is the conclusion of researchers at Scripps Institution of Oceanography at the University of California , San Diego, and the University of Washington in a review paper published in the November 17 issue of the journal Nature.
United States has 7th highest rate of primary forest loss
(11/16/2005) Primary forests are being replaced by "modified natural," "seminatural," and plantation forests in the United States according to new deforestation figures from the United Nations.
Five million tons of carbon dioxide successfully buried, DOE eyes Kyoto
(11/16/2005) Secretary Samuel W. Bodman today announced that the Department of Energy (DOE)-funded "Weyburn Project" successfully sequestered five million tons of carbon dioxide (CO2) into the Weyburn Oilfield in Saskatchewan, Canada, while doubling the field's oil recovery rate. If the methodology used in the Weyburn Project was successfully applied on a worldwide scale, one-third to one-half of CO2 emissions could be eliminated in the next 100 years and billions of barrels of oil could be recovered.
Photovoltaic solar energy conversion can be cost-competitive by 2030
(11/16/2005) Professor Andrew Blakers from The Centre for Sustainable Energy Systems at the Australian National University will today report to the Greenhouse 2000 Conference in Melbourne that photovoltaic (PV) solar energy conversion can be cost-competitive with any low-emission electricity generation technology by 2030.
Australia's freshwater ecosystems threatened by climate change
(11/16/2005) Australia's freshwater ecosystems are increasingly under threat from global warmning and expanding human population according to an interview of an Australian academic by The Age.
World deforestation rates and forest cover statistics, 2000-2005
(11/16/2005) Cambodia has the world's highest deforestation rate, Brazil loses the largest area of forest annually, and Congo consumes more bushmeat than any other tropical country. These are among the findings from mongabay.com's analysis of new deforestation figures from the United Nations. Monday, the Food and Agriculture Organization of the United Nations (FAO) released its 2005 Global Forest Resources Assessment, a regular report on the status world's forest resources. Overall, FAO concludes that net deforestation rates have fallen since the 1990-2000 period, but some 13 million hectares of the world's forests are still lost each year, including 6 million hectares of primary forests. Primary forests -- forests with no visible signs of past or present human activities -- are considered the most biologically diverse ecosystems on the planet.
Rain key to survival of baby lemurs
(11/14/2005) Researchers studying lemurs in Madagascar have discovered a link between tooth deterioration and rainfall amounts that suggests long-lived mammals may be particularly sensitive to changing environmental conditions--and that reproduction and infant survival is linked to tooth wear.
