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.

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.
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.

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.

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.

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.

The long-ignored ocean emergency and what can be done to address it
(08/18/2008) This year has been full of bad news regarding marine ecosystems: one-third of coral species threatened with extinction, dead-zones spread to 415 sites, half of U.S. reefs in fair or bad condition, increase in ocean acidification, tuna and shark populations collapsing, and only four percent of ocean considered pristine. Jeremy Jackson, director of the Scripps Center for Marine Biodiversity and Conservation at the University of California, San Diego, synthesizes such reports and others into a new paper, published in the journal Proceedings of the National Academy of Sciences, that boldly lays out the scope of the oceanic emergency and what urgently needs to be done.
New tree species discovered in Amazon biodiversity hotspot
(08/17/2008) I was walking down the Anaconda Trail at the Madre Selva Biological Station with botanist Rodolfo Vasquez when he suddenly stopped, stared at the bark of a 120-foot tree, and started searching the ground. Odd behavior? Perhaps, but when you're with Peru's top field botanist, odd behavior is forgivable, since it means that something interesting is probably afoot.
Markets could save rainforests: an interview with Andrew Mitchell
(08/17/2008) Markets may soon value rainforests as living entities rather than for just the commodities produced when they are cut down, said a tropical forest researcher speaking in June at a conservation biology conference in the South American country of Suriname. Andrew Mitchell, founder and director of the London-based Global Canopy Program (GCP), said he is encouraged by signs that investors are beginning to look at the value of services afforded by healthy forests.
Deforestation in the Brazilian Amazon won't increase significantly for 2008
(08/15/2008) Brazilian Environment Minister Carlos Minc said Thursday that Amazon deforestation for the 2007-2008 year will likely be comparable to the prior year.
