(03/15/2007) Earth could be reaching a tipping point that could trigger rapid climate change according to scientists studying declining sea ice in the Arctic.


Timber industry teams with greens on new anti-illegal logging bill

(03/15/2007) A bipartisan group of U.S. lawmakers introduced a bill to ban the use of illegally-harvested timber and wood products. Led by Congressmen Earl Blumenauer (D-OR), Robert Wexler (D-FL), and Jerry Weller (R-IL) the legislation would make it a crime to import, export, possess, purchase or sell illicit timber.


Asian pollution contributes to California warming

(03/14/2007) Pollution from Asia may cause warmer spring temperatures on the West Coast of the United States according to a new study led by scientists at the Scripps Institution of Oceanography, at the University of California San Diego.


New green biofuels process could meet all U.S. transportation needs

(03/14/2007) Purdue University chemical engineers have proposed a new environmentally friendly process for producing liquid fuels from plant matter - or biomass - potentially available from agricultural and forest waste, providing all of the fuel needed for "the entire U.S. transportation sector."


Pigeon beaks have navigation system

(03/14/2007) Birds may use sensors in their beaks to navigate long distances without getting lost according to a new study published in the scientific journal Naturwissenschaften. German scientists found iron-containing structures in the beaks of homing pigeons that might enable the birds to use the earth's magnetic field for navigation.


Clean coal is a vital energy source for the future says MIT report

(03/14/2007) Coal is a cheap and widely available energy source that will be continue to be used in the future despite its impact on global climate. For this reason, says a new report by MIT, it is essential to develop cleaner technologies for harnessing coal.


Ivory-billed Woodpecker sighting may be a mistake

(03/14/2007) A new study casts doubt on the apparent rediscovery of the Ivory-billed Woodpecker in Arkansas. J. Martin Collinson, a researcher at the University of Aberdeen in Scotland, says that the sighting of the thought-to-be-extinct bird is a case of mistaken identity. Using video analysis, Collinson argues that ornithologists have confused the Ivory-billed Woodpecker (Campephilus principalis) with the similar Pileated Woodpecker (Dryocopus pileatus).


New cat species discovered in Borneo

(03/14/2007) Scientists have declared that the clouded leopard found on the islands of Borneo and Sumatra is an entirely new species of cat, genetically distinct from the clouded leopard that lives in mainland southeast Asia. The scientists say that the two species of clouded leopard appear to have diverged about 1.4 million years ago. They also note that the results of the genetic study are supported by separate research on geographical variation in the coat color of the clouded leopard.


Amazon rainforest fires date back thousands of years

(03/14/2007) Fires are nothing new to the Amazon reports a study published in the journalBiotropica. Analyzing soils in the eastern Amazon, a team of scientists led by David S. Hammond of NWFS Consulting, has found evidence of forest fires dating back thousands of years. While the origin of these fires is unclear, the authors propose intriguing scenarios involving pre-Colombian human populations and ancient el Nino events which could have so dried rainforest areas that they became more prone to forest fires.


Rich countries gain, poor countries lose forest cover

(03/13/2007) Tropical deforestation rates continue to accelerate according to a bi-annual report from the Food and Agriculture Organization of the United Nations (FAO) released Tuesday.


Bush administration cuts funding for geothermal energy

(03/13/2007) The Bush Administration is seeking to eliminate federal funding for geothermal energy research according to a report from Reuters. Oddly, the move comes as the White House has made a push for renewable energy to reduce dependence on foreign oil imports. Apparently the administration appears to be focused on biofuels as liquid fuels and nuclear for electricity generation.


Newly discovered ocean genes could help address world problems

(03/13/2007) An expedition lead by genome pioneer Craig Venter has turned up more than 6 million unknown genes among ocean microbes, some of which could be used to help fight climate change and develop clean sources of energy, according to a study published in PLoS Biology, an open-access journal.


New bamboo species discovered in U.S., first in 200 years

(03/13/2007) Botanists have discovered a previously unknown species of North American bamboo in the hills of Appalachia. It is the third known species of bamboo in the United States, but the first new species in more than 200 years. The species is named Arundinaria appalachiana.


World population to peak at 9.2 billion in 2050

(03/13/2007) World population is expected to reach 9.2 billion by 2050 according to a new study by the United Nations. Virtually all growth will occur in developing countries, with their population growing from 5.4 billion today to 7.9 billion mid-century. The population of developed regions is expected to remain unchanged at 1.2 billion, and would have declined, were it not for the anticipated net migration from developing to developed countries.


UK to cut CO2 emissions by 60%

(03/13/2007) Tony Blair pledged Wednesday to cut Britain's carbon dioxide emissions by 60 percent by 2050 in an effort to fight global warming. In announcing the Climate Change Bill, Britain becomes the first country to set legally binding targets.


Caribbean coral reefs result of mass extinction, rise of isthmus

(03/12/2007) Extinctions that resulted from the formation of the Panamanian isthmus were delayed two million years according to a new study by researchers at the Smithsonian Tropical Research Institute, Scripps Institution of Oceanography and London's Natural History Museum. The findings may have implications for global species extinction and evolution.


Ancient humanoids were short and nasty for kung fu fighting, not climbing

(03/12/2007) Ancient ape-like human ancestors called as australopiths were short-legged to help them fight, not to climb trees, argues a new study from a researcher at the University of Utah.


Wind energy speculation jumps in Texas, but Exxon on sidelines

(03/12/2007) While speculative energy ventures are nothing new in Texas, today companies are taking risky gambles in wind power argues an article that appears in today's issue of The Wall Street Journal (WSJ). The WSJ reports that energy firms are investing hundreds of millions of dollars in some of the most remote -- and windy -- parts of Texas, but notes that the investments will only pay off with government subsidies.


Plug-in cars could help fuel Austin power grid

(03/12/2007) The city of Austin, Texas hopes to launch an ambitious plan using plug-in electric cars to reduce pollution and improve power grid management, reports an article in today's Wall Street Journal. Under the initiative put forth by Roger Duncan, deputy manager of Austin Energy, the city-owned electric utility, and backed by mayor Will Wynn, the plug-in electric cars would serve as sort of giant battery from which the city grid could draw power during peak demand.


Can new loan really bring sustainable cattle ranching to the Amazon?

(03/12/2007) Brazil's second largest exporter of beef has won approval of a controversial loan from the International Finance Corporation (IFC), the private equity lender of the World Bank, according to a report from the Associated Press. Environmentalists say the deal will drive further deforestation in the biologically rich Amazon rainforest. Cattle ranching is responsible for more than half of forest loss in the region.


Amazon rainforest does have rainy and dry seasons

(03/12/2007) A new study using NASA satellite images found evidence of seasonality in the Amazon rainforest. The results, published in the March 20 issue of the Proceedings of the National Academy of Sciences, show that the Amazon had 25 percent more leaf coverage in the dry season and 25 percent less in the rainy season.


Biodiversity extinction crisis looms says renowned biologist

(03/12/2007) While there is considerable debate over the scale at which biodiversity extinction is occurring, there is little doubt we are presently in an age where species loss is well above the established biological norm. Extinction has certainly occurred in the past, and in fact, it is the fate of all species, but today the rate appears to be at least 100 times the background rate of one species per million per year and may be headed towards a magnitude thousands of times greater. Few people know more about extinction than Dr. Peter Raven, director of the Missouri Botanical Garden. He is the author of hundreds of scientific papers and books, and has an encyclopedic list of achievements and accolades from a lifetime of biological research. These make him one of the world's preeminent biodiversity experts. He is also extremely worried about the present biodiversity crisis, one that has been termed the sixth great extinction.


New Snapper Species Discovered in Brazil

(03/09/2007) A new species of snapper was discovered off the coast of Brazil. The popular game fish had long been mistaken for a more common species, according to scientists with conservation International (CI) and Environmental Defense. The description of the Lutjanus alexandrei snapper is published in the journal Zootaxa.


Birds follow racoon-like coati to find food

(03/08/2007) A number of rainforest bird species are known to follow columns of army ants eating insects and other animals as they try to escape the marauding ants. Now the behvaior has been documented in birds that follow the coatimundi, a racoon-like mammal, as it forages in the rainforest.


Human hunting causes changes in monkey behvaior

(03/08/2007) Human hunting pressure causes significant behvaioral changes in Central Africa monkeys and duiker according to a paper published in the March issue of the journal Biotropica.


Air pollution can reduce rainfall

(03/08/2007) Air pollution can reduce rainfall in mountainous areas according to research published in Friday's issue of the journal Science. 50 years of measurements at Mt. Hua near Xi'an, in central China, show that precipitation levels can be decreased by 30 to 50 percent during hazy conditions. The researchers say this is the result of high concentrations of particulates in the air which cause cloud droplets to be smaller and less likely to become raindrops.


Carbon dioxide levels threaten oceans regardless of global warming

(03/08/2007) Rising levels of carbon dioxide will have wide-ranging impacts on the world's oceans regardless of climate change, reports a study published in the March 9, 2007, issue of the journal Geophysical Research Letters.


Jumbo squid and sperm whales tagged

(03/08/2007) Scientists have simulatenously tagged sperm whales and jumbo squid off Mexico's Pacific coast, allowing them to be tracked by satellite even as they dive to depths exceeding 3000 feet. Details of the effort are published in in the March 12 edition of the journal Marine Ecology Progress Series (MEPS).


Bush administration issues gag order on polar bear discussions

(03/08/2007) The Bush administration has banned discussion of polar bears, sea ice, and global warming among officials traveling overseas according to environmental groups and the director of the U.S. Fish and Wildlife Service.


Government pledges $385M for cellulosic ethanol

(03/08/2007) The U.S. Department of Energy (DOE) announced it will invest up to $385 million over the next four years for six biorefinery projects capable of producing more than 130 million gallons of cellulosic ethanol annually.


Deforestation causes species extinction in Madagascar

(03/07/2007) Deforestation has already caused the extinction of a large number of endemic insect species on the island of Madagascar, according to new research published in the March edition of the journal Biology Letters. The work suggests that only half the species confined to these forest areas will survive.


Ecuadorian brothers show conservation-based microentrepreneurship possible

(03/07/2007) Tropical rainforests are declining across most of the world. Since the close of the 1990s deforestation rates have only accelerated as growing levels of consumption and consistent population growth paint an increasingly bleak future for the world's forests and their resident biodiversity. These trends make it easy to lose hope. As such, stories that show local people earning a livelihood from biodiversity conservation are an inspiration.


World's only blue lizard heads toward extinction

(03/07/2007) High above the forest floor on the remote Colombian island of Gorgona lives a lizard with brilliant blue skin, rivaling the color of the sky. Anolis gorgonae, or the blue anole, is a species so elusive and rare, that scientists have been unable to give even an estimate of its population. Due to the lizard&spod;s isolated habitat and reclusive habits, researchers know little about the blue anole, but are captivated by its stunning coloration.


Panama Canal port projects threaten mangroves

(03/06/2007) Port development and land speculation in Panama is turning some of the Caribbean's most productive mangrove forests into landfill. The landfill would be used for container storage near the city of Colon, at the mouth of the Panama Canal. But local scientists say the transformation could have unintended environmental consequences.


Termites can make ethanol

(03/06/2007) Achim Steiner, Executive Director of the UN Environment Programme (UNEP), says that termites can be used to make eco-friendly ethanol. He cites U.S. government backed research showing that "microbes living in the guts of termites have potent enzymes able to efficiently and cost effectively transform woody wastes into sugars for ethanol production."


Billion Tree Campaign gets pledges totaling 562M trees since January

(03/06/2007) The UN Environment Programme (UNEP) announced that its 'Billion Tree Campaign' has so-far achieved commitments to plant 562,769,095 trees, following a pledge of 250 million trees by the Ministry of Environment and Natural Resources of Mexico.


GM plans electric car for 2010

(03/06/2007) Underperforming U.S. automaker General Motors said it has set a 2010 target for production of an-electric car according to a statement from Vice Chairman Bob Lutz, as reported by Reuters.


Bird species rediscovered after 139 years

(03/06/2007) A wetland bird that has been 'lost' for nearly 140 years was rediscovered at a wastewater treatment plant in Thailand according to bird conservation group BirdLife International.


Pre-Colombian Amazon rainforest not heavily populated

(03/06/2007) Much of the Amazon rainforest was not heavily populated by pre-Colombian indigenous cultures argues a new paper published in the journal Philosophical Transactions of the Royal Society B: Biological Sciences. The work challenges an increasingly accepted theory -- popularized in Charles C. Mann's 1491: 'New Revelations of the Americas Before Columbus' -- the Amazon supported dense, sedentary populations prior to the arrival of Europeans.


Gold mining in Guyana damages environment, threatens Amerindians

(03/06/2007) Informal gold mining is causing environmental harm and human rights abuses in Guyana says a new report from the International Human Rights Clinic (IHRC) of Harvard Law School's Human Rights Program. Wildcat gold mining has been a serious problem in the Guiana shield countries of Brazil, Venezuela, Guyana, Suriname and French Guiana. Rising gold prices in recent years have only worsened the problem, as illegal miners have flooded the region clearing forest, polluting rivers, and making threats against indigenous people.


Two new species of eyeless albino millipede found in Arizona

(03/05/2007) A newly discovered genus of millipede may shed light on the poorly understood cave ecosystems of the desert southwest. J. Judson Wynne, with the Department of Biological Sciences at Northern Arizona University (NAU) and cave research scientist with the U.S. Geological Survey's Southwest Biological Center, and Kyle Voyles, Arizona State Cave Coordinator for the Bureau of Land Management (BLM), collected the two previously unknown millipede species in caves on opposite sides of the Grand Canyon.

(03/05/2007) Growing levels of pollution in Asia are altering the chemistry of the atmosphere and causing a change in Pacific storm patterns according to researchers writing in the online early edition of PNAS


Birds exhibit thuggish mafia-like behvaior as nest enforcers

(03/05/2007) Parasitic birds engage in mafia-like reprisals to encourage host acceptance of their eggs according to researchers writing in the online early edition of PNAS.


Ozone ban has been more effective in fighting global warming than Kyoto Protocol

(03/05/2007) The 1987 Montreal Protocol, which restricted the use of ozone-depleting substances, has helped slow the rate of global warming in addition to protecting the ozone layer, report scientists writing in a paper published online in the early edition of PNAS.


Farming in the rainforest can preserve biodiversity, ecological services

(03/05/2007) While conversion of tropical forest for agriculture results in significant declines in biodiversity and carbon storage, an analysis of Indonesian rainforests shows that farming cacao under the partial shade of high canopy trees can provide a way to balance economic gain with environmental considerations.


Global warming causing disappearance of tundra in Canada

(03/05/2007) Tundra in northern Canada is being replaced at a rapid rate by boreal forests according to a new study published in the Journal of Ecology. Researchers say global warming is to blame.


Coral species may help fight global warming impact

(03/04/2007) While many coral species appear to be potentially doomed by global warming, some species may help fight the impact of climate change, in effect helping protect coral reef ecosystems, argues a Cornell University biologist.


Fish extinctions alter critical nutrients in water, study shows

(03/03/2007) Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out. Now, a Cornell study using computer simulations has teased out how the disappearance of a freshwater fish can affect the availability of certain nutrients that other species rely on.


U.S. GHG emissions to rise 20% by 2020

(03/03/2007) The United States expects to emit 19 percent more greenhouse gases in 2020 than it did in 2020 according to a report from the Associated Press. The draft report, which is still in progress and is more than a year late, projects 9.2 billion tons of greenhouse gas emissions in 2020, a 19 percent increase from 7.7 billion tons in 2000, if the Bush Administration climate policy proceeds as planned.


Tradable biodiversity rights can help to conserve species richness

(03/02/2007) The decline in biodiversity compels us to look at the sustainable use of living resources in a different manner. To conserve biodiversity, the social and economic aspects of the use of biodiversity must be taken into account, in addition to the ecological aspects. From this perspective it then becomes clear, for example, that the portion of the world population that lives in poverty is incapable of contributing to the conservation of biodiversity. In their daily search for food, energy and shelter, they simply cannot pay attention to this aspect. Professor Steven De Bie made this point during his acceptance of the endowed chair in the Sustainable Use of Living Resources on 1 March at Wageningen University. To compensate for this decline in biodiversity in the poorer regions, De Bie proposes establishing tradable 'biodiversity rights'.
