conservation news and environmental science news.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. Mysterious carnivore found in Borneo rain forest (12/05/2005) WWF researchers may have discovered a new, mysterious carnivore species in the dense, central forests of Borneo. Elevated atmospheric CO2 increases soil carbon (12/05/2005) An article in the current issue of Global Change Biology indicates that soils in temperate ecosystems might contribute more to partially offsetting the effects of rising atmospheric CO2 concentrations than earlier studies have suggested. Amazon deforestation slows in Brazil for 2005 (12/05/2005) Deforestation in the Amazon rainforest fell 37% for the 2004-2004 year according to Brazilian government figures released today. Between July 2004 and August 2005, 7,298 square miles of rainforest (18,900 square kilometers) -- an area almost half the size of Switzerland -- were destroyed. 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. Governments making progress in fight against illegal logging says FAO (12/03/2005) Governments are becoming increasingly innovative in devising ways to control illegal logging claims new research released by the Food and Agriculture Organization of the United Nations and the International Tropical Timber Organization. Poisonous volcanic gas probably caused worst mass extinction says new study (12/02/2005) The mass extinction event at the end of the Permian -- where more than two-thirds of reptile and amphibian families perished and 95% of oceans life forms became extinct -- was probably caused by poisonous volcanic gas, according to research published in the journal Geology. The researchers believe that volcanic gases from the eruption depleted earth's protective ozone layer and acidified the land and sea. Tropical Atlantic cooling and deforestation correlate to drought in Africa (12/02/2005) Against the backdrop of the Montreal Summit on global climate being held this week, an article on African droughts and monsoons, by a University of California, Santa Barbara scientist and others, which appears in the December issue of the journal Geology, underlines concern about the effects of global climate change. US denies hurricane link with climate change (12/01/2005) Harlan Watson, chief climate control negotiator for the U.S. State Department, told the Associated Press that the Bush administration does not blame global warming or climate change for extreme weather -- including the hurricanes that thrashed the Gulf earlier this year. Crystal sponges can absorb carbon dioxide and fight global warming (12/01/2005) Since the Industrial Revolution, levels of carbon dioxide---a major contributor to the greenhouse effect---have been on the rise, prompting scientists to search for ways of counteracting the trend. One of the main strategies is removing carbon dioxide (CO2) from the flue exhaust of power plants, using porous materials that take up the gas as it travels up the flue. Biosensor Could Help People with Parkinson's, Alzheimer's Disease (12/01/2005) An engineering researcher at the University of Arkansas has developed a wireless, implantable biosensor that may one day help physicians treat patients with neurological brain disorders such as Parkinson's Disease, Alzheimer's Disease and epilepsy. Made of carbon nanotubes, the sensor monitors and controls chemicals in the brain and communicates with other sensors to control tremors or direct the movement of prosthetic limbs. Change in Atlantic circulation could plunge Europe into cold winters (12/01/2005) The Atlantic Ocean circulation that carries warm waters north and returns cold waters south is slowing, putting Europe at risk of colder temperatures, according to research published in Nature. The Atlantic Heat Conveyor, the system of currents in the Atlantic Ocean that result in a net transport of warm water into the northern hemisphere, keeps western Europe warmer than regions at similar latitudes in other parts of the world. A weakening of the system, which includes the Gulf Stream, could cause a cooling in northwest Europe. Giant, human-sized scorpion discovered (12/01/2005) Tracks made 330 million years ago by a 1.6 meter-long (5 ft 3 inches) water scorpion have been discovered in Scotland. U.S. fishing bycatch wastes 1 million metric tons of fish per year (12/01/2005) A new study shows that for every five pounds of fish caught by U.S. commercial fisheries, one pound is dumped -- dead, dying and wasted. Each year, U.S. commercial fishing operations throw away more than one million metric tons of fish, an amount equivalent to 28 percent of all commercial landings and more than all of the fish landed on the East and West coasts combined. Overfishing of fresh waters of serious concern (12/01/2005) Systematic overfishing of fresh waters occurs worldwide but is largely unrecognized because of weak reporting and because other pressures can obscure fishery declines, according to an article in the December 2005 issue of BioScience. 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. Australian industry embraces green energy while government fights emissions cuts (12/01/2005) Despite Australia's resistance to limiting carbon dioxide emissions through the Kyoto Protocol, Australian industry and entrepreneurs are working on novel ways to reduce dependence on traditional fossil fuels. Scientists taking a multidisciplinary approach to understanding nature (12/01/2005) Improved tools and increasingly sophisticated approaches are helping researchers at Oak Ridge National Laboratory gain a better understanding of how organisms respond to and interact with their environment. Toucan Beaks Are Models Of Lightweight Strength says UCSD engineer (11/30/2005) As a boy growing up in Brazil 40 years ago, Marc A. Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now a materials scientist and professor of mechanical and aerospace engineering at UCSD's Jacobs School of Engineering, Meyers said makers of airplanes and automobiles may benefit from the first ever detailed engineering analysis of toucan beaks conducted in his lab. 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. Rise in deer ticks put East Coast hikers at risk says Penn State entomologist (11/30/2005) Every year it seems the tick identification laboratory in Penn State's entomology department receives more submissions from residents around the state than the year before. But Steven Jacobs, the extension entomologist who oversees the lab, said this year is different. Young women smokers have higher risk of breast cancer (11/30/2005) Researchers outline in the November issue of Mayo Clinic Proceedings their study of postmenopausal women, which supports the hypothesis that women who smoke cigarettes before first full-term pregnancy have a 20 percent increased risk of breast cancer compared with women who began smoking after the birth of their first child or were never smokers. 75% of Switzerland's glaciers gone by 2050, Europe heats up (11/30/2005) The four hottest years on record were 1998, 2002, 2003 and 2004. Ten percent of Alpine glaciers disappeared during the summer of 2003 alone. At current rates, three quarters of Switzerland's glaciers will have melted by 2050. Europe has not seen climate changes on this scale for 5 000 years, says a new report by the European Environment Agency. Bird songs can serve as a warning system to detect ecological disturbances (11/30/2005) Changes in bird song could be used as an early warning system to detect man-made ecological disturbances, new research published in the British Ecological Society's Journal of Applied Ecology has found. Rainforests worth $1.1 trillion for carbon alone in Coalition nations (11/29/2005) If a coalition of developing countries has its way, there could soon be new forests sprouting up in tropical regions. The group of ten countries, led by Papua New Guinea, has proposed that wealthy countries pay them to preserve their rainforests. The Coalition for Rainforest Nations argues that all countries should pay for the benefits -- from carbon sequestration to watershed protection -- that tropical rainforests provide. 2005 Atlantic hurricane season worst on record (11/29/2005) The 2005 Atlantic hurricane season is the busiest on record and extends the active hurricane cycle that began in 1995 -- a trend likely to continue for years to come. The season included 26 named storms, including 13 hurricanes in which seven were major. Dire consequences if global warming exceeds 2 degrees says IUCN (11/29/2005) The parties to the United Nations Framework Convention on Climate Change must keep global warming below 2 degrees Celsius, says the World conservation Union. Vaccination can prevent bird flu epidemic (11/28/2005) Vaccinating chickens against avian flu can prevent a major outbreak of the disease by preventing birds from passing on the virus, according to research published by Dutch scientists on Monday. Atmospheric carbon dioxide levels closely correlated with global temperatures (11/28/2005) Studying ice cores from Antarctica, scientists of the Alfred Wegener Institute for Polar and Marine Research extended the record of historic concentrations of carbon dioxide, methane and nitrous oxide in the atmosphere by 250,000 years. The team found a close correlation between atmospheric carbon dioxide levels and global temperatures. Over the past 650,000 years, low greenhouse gas concentrations have been associated with cooler conditions. The current concentration of atmospheric carbon dioxide, at 380 parts-per-million, is the highest level recorded over the past 650,000 years. Developing countries: pay us to save rainforests (11/27/2005) At this week's United Nations summit on climate change in Montreal a coalition of tropical developing countries plans to propose that wealthy countries pay them to preserve their rainforests. The group of 10 countries, led by Papua New Guinea and Costa Rica, will argue that they should be compensated for the services rainforests provide the rest of the world. Average temperatures climbing faster than thought in North America (11/27/2005) Tree rings and borehole drill samples have added to the evidence that average temperatures in North America have risen steadily in the past 150 years according to a new study by researchers at Oregon State University and the University of Utah. In their paper published in Journal of Geophysical Research, scientists found that average temperatures in the Northern Hemisphere increased about 1.5 degrees since the beginning of the industrial revolution when atmospheric carbon dioxide concentrations began to increase sharply. Exploring freshwater fish habitats in the rainforest of Peru (11/26/2005) This fall the editor of mongabay.com, a leading environmental science and tropical freshwater fish information site, traveled to the Peruvian Amazon and examined habitats for freshwater fish. As a result of this effort, two new biotope descriptions have been posted on the site. The descriptions include underwater photographs for those interested in replicating the natural conditions of these habitats. "Health" beer could help prevent cancer (11/26/2005) A compound found only in hops and the main product they are used in - beer - has rapidly gained interest as a micronutrient that might help prevent many types of cancer. Oil sands' development for energy a threat to environment says group (11/25/2005) Wednesday the Pembina Institute released "Oil Sands Fever: The Environmental Implications of Canada's Oil Sands Rush" [PDF]. According to the report's main author, Dan Woynillowicz, "The story of Canada's rapid development of the oil sands has only been partially told. What's been missing from all the discussion and reporting is a comprehensive look at the environmental consequences of this development". Singing iceberg discovered in Antarctica (11/25/2005) Scientists believe they have found a singing iceberg in Antarctica, according to research published in Science on Friday. Ocean levels rising twice as fast (11/25/2005) Global ocean levels are rising twice as fast today as they were 150 years ago according to research presented in Science by a team of researchers. The Using core samples of sediments along the New Jersey coast, the scientists found that rates of sea level change have climbed significantly over the past 200 years, coinciding with the beginning of the industrial revolutions when carbon dioxide emissions began to dramatically increase. Carbon dioxide is the principal greenhouse gas believed to contribute to global warming. Carbon in Canada's boreal forest worth $3.7 trillion (11/25/2005) Carbon stored in Canada's boreal forests and peatlands is worth $3.7 trillion according to research by the Pembina Institute for the Canadian Boreal Initiative. Rising seas and disappearing islands will produce environmental refugees (11/24/2005) The Carteret Islands are almost invisible on a map of the South Pacific, but the horseshoe scattering of atolls is on the front-line of climate change, as rising sea levels and storm surges eat away at their existence. Children spread malaria most says new study (11/24/2005) Children should be the focus malaria control efforts as they are ones most likely to be bitten by mosquitoes carrying the parasite, according to new research published in Nature. Carbon dioxide at highest level in 650,000 years (11/24/2005) Carbon dioxide levels are now 27 percent higher than at any point in the last 650,000 years, according to research into Antarctic ice cores published on Thursday in Science. Will 'tipping points' accelerate global warming? (11/24/2005) Rising temperatures trigger a runaway melt of Greenland's ice sheet, raising sea levels and drowning Pacific islands and cities from New York to Tokyo. Eco-friendly palm oil coming soon, criteria could result in cleaner biofuels (11/23/2005) Consumers can soon enjoy soap, shampoos and many other products containing palm oil with a clean conscience following overwhelmingly acceptance by the Roundtable for Sustainable Palm Oil (RSPO) -- a group of producers, buyers, retailers, financial institutions and NGOs -- on a set of criteria for the responsible production of palm oil. Climate change already affecting Europeans says WWF "Climate Witnesses" (11/23/2005) Five WWF "Climate Witnesses" from the UK, Germany, Italy and Spain descended on Brussels to tell their personal stories of how climate change is affecting their lives and businesses. Snow disappearing in Scotland, fewer bees in Italy, crop losses in Spain, forests on the decline in Germany and sea levels rising off the coast of England are dangerous signs of climate change in Europe. 25% of Americans live in places compliant with Kyoto protocol (11/23/2005) Even though the United States does not participate in the Kyoto protocol, about one-quarter of the population lives in states, counties or cities that have adopted climate change policies similar to those of the global initiative, according to a Brief Communication published in the November 17 issue of Nature. Goldman Sachs first investment bank to adopt comprehensive environmental policy (11/22/2005) The Rainforest Action Network (RAN) today issued a release commending Goldman Sachs for becoming the first global investment bank to adopt a comprehensive environmental policy. The policy acknowledges the scientific consensus on climate change and calls for urgent action by public policy makers and federal regulators to reduce greenhouse gas emissions. Britain is largest importer of illegal timber in EU says WWF (11/21/2005) Britain is the biggest importer of illegally-logged timber in Europe, responsible for the destruction of 1.4 million acres of forest a year according to a new report by the World Wildlife Fund for Nature (WWF). 203 million people malnourished in sub-Saharan Africa (11/21/2005) Hunger and malnutrition kill nearly 6 million children a year, and more people are malnourished in sub-Saharan Africa this decade than in the 1990s, according to a report released by the Food and Agriculture Organization Tuesday. In sub-Saharan Africa, the number of malnourished people grew to 203.5 million people in 2000-02 from 170.4 million 10 years earlier says "The State of Food Insecurity in the World" report. Forests flushed down the toilet (11/21/2005) The major tissue manufacturers are not offering enough recycled toilet paper, towels and napkins to European consumers and must be more responsible when sourcing their wood, according to a new WWF report. G8 aid for Africa under threat from climate change (11/21/2005) An increase in aid for Africa agreed at the Gleneagles summit may be entirely consumed by the cost of dealing with climate change, the President of the Royal Society, the UK national academy of science, has warned Margaret Beckett and other G8 energy and environment ministers in an open letter published ahead of their key climate change meeting in London on 1 November. Underwater sound pollution threat to marine life says new report (11/21/2005) New evidence shows that the rising level of intense underwater sound produced by oil and gas exploration, military sonar and other manmade sources poses a significant long-term threat to whales, dolphins, fish and other marine species, according to a report published today by the Natural Resources Defense Council (NRDC).
