Powerful hurricanes may be getting stronger due to warmer seas
(09/03/2008) Warming climate is causing the strongest hurricanes to strengthen and more moderate storms to stay the same, claims a new study published in Nature. However the data on which research is based is already facing fierce criticism.
Canada's ice shelves lost 23% of their area this summer
(09/03/2008) A 19-square-mile (50 sq km) chuck of ice shelf broke off from Canada's Ellesmere Island in the northern Arctic, reports the Associated Press. The Manhattan-sized ice shelf is now adrift in the Arctic Ocean. It is the largest of more than 83 sq mi (214 sq km) of ice shelf that has broken up in the Canadian Arctic this year.
For Australian beetles bigger is better; while American beetles don't care about size
(09/03/2008) Researchers have discovered a dung beetle that may be evolving into separate species in a few decades rather than thousands or millions of years. Separated geographically, sub-populations of the species show large differences in the size of their genitalia and horns. Such distinctions could create new species in a short time, because beetles with largely different genitalia cannot successfully mate.
Independent of climate, forest cover in southern Amazon may fall to 20% by 2016
(09/03/2008) Forest cover in the "Arc of Deforestation" of southern Amazonia will decline to around 20 percent 2016 due to continued logging and conversion of forests for cattle pasture and soy farms, report researchers writing in the journal Environmental Conservation. Analyzing high resolution satellite data from 1984 through 2004 for the Alta Floresta region in northern Mato Grosso, Fernanda Michalski, Carlos Peres and Iain Lake of the University of East Anglia found that forest cover declined from from 91.1 percent to 41.7 percent between 1984 and 2004. They note that while the deforestation rate has slowed to around 2 percent per year since peaking at more than 8 percent annually in late 1980s to mid-1990s, renewed expansion of road networks will enable loggers to increasingly exploit remaining forests, leading to degradation and likely eventual conversion for agricultural use. Overall Michalski and colleagues forecast that forest cover in Alta Floresta will fall to 21 percent by 2016, a decline of 77 percent since 1984.
Did prehistoric farmers drive early global warming?
(09/03/2008) In 2003 William Ruddiman put forth a controversial theory: 7,000 years ago the rise of agriculture spawned large-scale climatic changes. According to Ruddiman, the felling of forests for fields throughout Europe and Asia caused a rise in carbon dioxide, while the flooded fields for rice released methane gas. This combination of large amounts of carbon dioxide and methane entering the atmosphere caused the globe to warm, preventing the planet from entering another ice age.
Whale meat is back on the menu in Iceland

Indonesian raids on tiger traffickers yielding arrests in Sumatra
(09/02/2008) A raid on illegal tiger traders in Indonesia resulted in four arrests in Sumatra, reports the Wildlife Conservation Society (WCS). The arrests come under a new crack-down by Indonesian authorities on the sales of tiger parts. 10 traffickers have been arrested in the past 3 months.
When in season, wolves choose salmon over deer
(09/02/2008) The popular image of hunting wolves is a pack bearing down on a deer, working in concert to make the kill. However, new research has discovered that when available, wolves largely forgo hoofed mammals for salmon.
Scientist forecast 4 Atlantic hurricanes in September
(09/02/2008) Prominent hurricane researchers are forecasting five tropical storms in the Atlantic for September, including four hurricanes. Two of these are expected to be "major" — category 3 or greater. Retired Colorado State University climatologist William Gray and Philip J. Klotzbach, who has taken over Gray's role as lead hurricane forecaster, estimate that Atlantic storms in September will be twice as active as normal.
Researchers devise new comparison of mass extinction events
(09/02/2008) Researchers have created a new way to compare historical mass extinction events. The scoring system, presented in the early online edition of the journal Proceedings of the National Academy of Sciences, works by multiplying the number of taxa — species, genera, and families — that went extinct by the inverse of the time it took to produce a measure dubbed "greatness", which represents the magnitude of the event. Using the system, Celal Sengor and colleagues from Istanbul Teknik Universitesi of Turkey rank the Cretaceous-Tertiary (K-T) event — when the dinosaurs were extinguished in a flash by an asteroid strike or mass oceanic poisoning by a spasm of volcanic activity — as the greatest mass extinction in history. The Permian, which featured a greater loss of species (90-95 percent of marine species and 70 percent of land species) but played out over a longer period to time some 250 million years ago, ranks third after the Silurian, which occurred around 440 million years ago.
Melting permafrost will be major driver of global warming
(09/01/2008) The thawing of permafrost in northern latitudes will become a major source of greenhouse gas emissions, according to a new study that more than doubles previous estimates of the amount of carbon stored in the frozen soils of Alaska and Siberia.
Carbon market may fund dam in Panama that threatens natural reserve
(09/01/2008) The UN's Clean Development Mechanism (CDM) — a scheme that provides funds to projects that reduce emissions in developing nations — may be used to finance a hydroelectric dam in Panama which, according to environmentalists, threatens a biologically rich World Heritage site and an indigenous tribe, the Ngobe.
Past decade is warmest in at least 1300 years
(09/01/2008) A reconstruction of surface temperatures over the past two thousand years provides further evidence that the northern hemisphere is now warmer than at any time in at least 1300 years. The research, published in the online edition of the Proceedings of the National Academy of Sciences, in the Northern Hemisphere are higher than those of the Medieval warm period.
Could hurricane Gustav be stopped or diverted?
(08/31/2008) With Gustav threatening to become the second major hurricane to hit New Orleans in three years, the question emerges, is there something that could be done to redirect or at least diminish storms from major population areas? In short, the answer is no, although someday there may be ways to reduce the intensity of these tropical storms. In the meantime, the best option is to avoid new construction in hurricane-prone regions.
Amazon deforestation jumps 69% in 2008
(08/31/2008) Deforestation in the Brazilian Amazon increased 69 percent in the past 12 months as high commodity prices have driven forest conversion for ranches and cropland, according to preliminary figures released by Brazil's National Institute for Space Research (INPE). The increase comes after three consecutive years of declining deforestation in Brazil.
Indian protesters win land rights battle against Peru's President Garcia
(08/31/2008) Peru's Congress rejected two decrees by President Alan García that made it easier for foreign developers to buy Amazon rainforest land. The repeal came just two days after lawmakers struck a deal with indigenous rights groups whose protests over the law had shut down oil and gas operations. The groups were worried that the laws weakened their land rights in favor of loggers, miners, and drillers.

Two large populations of endangered monkeys discovered in Cambodia
(08/28/2008) Conservationists have discovered "surprisingly large populations" of two globally threatened primates in a protected area in Cambodia. Surveys by scientists with the Bronx Zoo-based Wildlife Conservation Society (WCS) and the Cambodian government counted 42,000 black-shanked douc langurs and 2,500 yellow-cheeked crested gibbons in Cambodia's Seima Biodiversity Conservation Area.
Pre-Colombian Amazonians lived in sustainable 'urban' society
(08/28/2008) Researchers have uncovered new evidence to support the controversial theory that parts of the Amazon were home to dense "urban" settlements prior to the arrival of Europeans in the 15th century. The study is published this Friday in the journal Science. Conducting archeological excavations and aerial imagery across a number of sites in the Upper Xingu region of the Brazilian Amazon, a team of researchers led by Michael Heckenberger found evidence of a grid-like pattern of 150-acre towns and smaller villages, connected by complex road networks and arranged around large plazas where public rituals would take place. The authors argue that the discoveries indicate parts of the Amazon supported "urban" societies based around agriculture, forest management, and fish farming.
40% of Australia is undisturbed wilderness
(08/27/2008) More than 40 percent of Australia—three million square kilometers—is undisturbed wilderness, reports a new study by Pew Environment Group and Nature Conservancy. The extent of Australia's wildlands ranks with the Amazon rainforest, Antarctica, Canada's boreal forest, and the Sahara as the largest on the planet.

Scientists condemn Bush plan for endangered species
(08/27/2008) The Ecological Society of America has come down handily against the Bush Administration's proposed changes to the Endangered Species Act (ESA). The changes would eliminate the requirement for independent scientific review of federal projects, such as roads, dams, and mines, instead allowing federal agencies to conduct internal evaluations and then proceed as they see fit.
Sea ice extent falls to second lowest on record
(08/27/2008) Arctic sea ice extent presently stands at it second-lowest level on record and could set a new low in coming weeks, reports the National Snow and Ice Data Center (NSIDC).
Biofuels 200 times more expensive than forest conservation for global warming mitigation
(08/27/2008) The British government should end subsidies for biofuels and instead use the funds to slow destruction of rainforests and tropical peatlands argues a new report issued by a U.K.-based think tank. The study, titled "The Root of the Matter" and published by Policy Exchange, says that "avoided deforestation" would be a more cost-effective way to address climate change, since land use change generates more emissions than the entire global transport sector and offers ancillary benefits including important ecosystem services.
Baltic cod are shrinking due to overfishing
(08/26/2008) By comparing Neolithic cod with contemporary cod, researchers have discovered that the species has evolved over a relatively short period due to overexploitation by humans. According to a paper published in Proceedings of the Royal Society B, contemporary cod attain adulthood earlier and are generally smaller than their ancestors.

The extinction of the baiji a 'wake-up call' to conserve vaquita and other cetaceans
(08/25/2008) In December of 2006 an expedition spent six weeks surveying the Yangtze River in China for one of the world's rarest cetaceans, the baiji. Also known as 'The Goddess of the Yangtze' the shy river-dolphin had roamed the river for millions of years locating fish with echolocation. The survey came back empty-handed without a spotting a single dolphin. Dr. Jay Barlow, a member of the surveying team, described his emotions on the expedition's findings in an interview with Mongabay.com: "I was stunned. I knew the species was in trouble, but I did not think they were already gone. We really had not seen the extinction of a large mammal species in 50 years, so we grew complacent."
Climate change may increase global conflict
(08/25/2008) The signs of a warming world are everywhere: birds are migrating with changing temperatures; coral reefs are dying out due to bleaching; warmer winters are allowing beetles to devour Canadian forests; and the Northwest Passage has opened for the second year in a row. While scientists work to understand how climate change is affecting the worldÕs ecosystems, others are attempting to predict how societies may respond. Jurgen Scheffran, a scientist with the Program in Arms Control, Disarmament and International Security at the University of Illinois, believes a warmer world will lead to an increase in armed conflicts. He concludes that societies stressed by increased competition for natural resources are more likely to engage in warfare.
How do wind turbines kill bats?
(08/25/2008) Numerous studies have shown that migratory bats are undergoing large fatalities due to wind turbines. Far more bats die due to wind turbines than birds, though they generally receive less attention. Now, researchers writing in Current Biology believe they know why bats are more susceptible to wind turbine fatalities.

The agreement was announced Sunday, August 17, 2008.
Presidential candidate John McCain's love-hate relationship with bears
(08/21/2008) Senator John McCain has frequently cited an earmark to a bill proving funds for a study of grizzly bears in Montana as an example of the worst pork-and-barrel spending in Washington. The study was included in an ad for McCain entitled "Outrageous" during the primaries. However, according to FactCheck.org, Senator McCain voted for the earmark he now derides.
French birds on the move due to climate change—just not fast enough
(08/21/2008) French ornithologists have discovered, year by year, that French birds are moving north due to the affects of climate change. A recent study of such movements in the Royal Society journal Proceedings B concludes that the birds are not moving fast enough, leading to concern among conservationists.

There is enough water for everyone provided it is well-managed and distributed
(08/21/2008) An increasingly-popular view of our future is an exponentially thirsty world where billions lack access to fresh water, leading to widespread famine and wars over water instead of oil. If this sounds like science fiction, the UN has predicted that by 2050 seven billion people will suffer from water scarcity. Putting that number in perspective: today's entire global population is not yet seven billion people.
When the magpie looks in a mirror, it sees itself
(08/20/2008) Unlike Narcissus of Greek mythology--who upon seeing his reflection in water jumped in thinking it was another--magpies have proven they can recognize their own reflections. Until now, only a small number of primates (chimpanzees, pygmy chimps, and orangutans) have displayed this ability, making the magpie the first bird shown to recognize itself.
Mangrove species flourishes in the United Arab Emirates after a century of local extinction
(08/20/2008) A long-absent mangrove species is flowering again in the United Arab Emirates a hundred years since its disappearance. Seeds of the rhizophora mucronata were brought from Pakistan and planted along the coast. The project was a joint venture between the United Arab Emirate's (UAE) Department of President's Affairs and the Environment Agency-Abu Dhabi.
