Earth already committed to 2.4-degree C rise from climate change
(09/15/2008) As of 2005 the Earth was already committed to rise of global mean temperatures by 2.4°C (4.3°F), concludes a new study published in the journal Proceedings of the National Academy of Sciences (PNAS). The conclusion is significant because the Intergovernmental Panel on Climate Change (IPCC) has warned that a rise in global temperature by 1 to 3°C will lead to catastrophic consequences, including “widespread loss of biodiversity, widespread deglaciation of the Greenland Ice Sheet, and a major reduction of area and volume of Hindu-Kush-Himalaya-Tibetan glaciers, which provide the head-waters for most major river systems of Asia.” These glaciers, predicted to shrink considerably in the next few decades, provide food and water to over two billion people.
Commercial bushmeat trade is devastating wildlife

Whaling Commission issues media blackout on discussions to lift whale killing ban
(09/11/2008) The survival of whales is perhaps the most successful conservation story of the 20th century. Since a moratorium on commercial hunting, some whale species have staged dramatic recoveries. In May it was announced that the humpback whale population has climbed from 1,500 to 20,000 individuals, resulting in it being "downlisted" from vulnerable to least concern, according to the IUCN's Red List. Others, like the blue whale, appear to have stable populations but recovery remains slow.

Moose Mission in New York's Adirondacks
(09/05/2008) Bushwhacking our way through nearly impenetrable bogs and blow down in the central woods of the Adirondacks in northern New York, I am wondering…how can a MOOSE move through this stuff? Weighing nearly 1400 pounds and standing six to seven feet tall, moose favor the dense mixed forests that surround the lakes and ponds of the Adirondacks, the largest publicly protected area in the contiguous United States. About 6 million acres of boreal forests, mountains, and lakes in northern New York are within the boundaries of the Adirondacks, half of which are public lands, the other half are private. The relatively cool climate and available plants on the many riparian banks of the area make for a moose mecca.

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.

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.
