(02/25/2008) Climate models increasingly forecast a dire future for the Amazon rainforest. These projections are partly based on recent research that has linked drought in the Amazon to sea surface temperatures in the tropical Atlantic. As the tropical Atlantic warms, the southern Amazon -- the agricultural heartland of Brazil -- may see higher temperatures and less rainfall.
Deforestation a greater threat to the Amazon than global warming
(02/25/2008) If past conditions are any indication of future conditions, the Amazon rainforest may survive considerable drying and warming caused by global warming, argue researchers in a paper published in Philosophical Transactions of the Royal Society B.
Widespread butterflyfish may go extinct due to global warming, pollution
(02/24/2008) The Chevroned Butterflyfish, a colorful fish found in tropical oceans around the world, faces extinction due to overexploitation, pollution and climate change, report researchers writing in the journal Behavioural Ecology and Sociobiology. Despite its widespread distribution, the species could be doomed by its specialized feeding habitats: the Chevroned Butterflyfish (Chaetodon trifascialis) feeds on only one type of coral.
Amazon research and conservation cannot ignore social issues
(02/24/2008) For Amazonian conservation to be effective it must start paying more attention to social issues according to a new paper: Taking things public: a contribution to address human dimensions of environmental change. The paper's author, Dr. Diogenes Alves, of the National Institute for Space Research told mongabay.com that "the main point of this paper is that it became crucial to recognize the social, economic and political settings associated with environmental change in the Amazon."

Is Guyana's logging deal in its best interests?
(02/21/2008) In January Guyana awarded U.S. timber firm Simon & Shock International a 400,000-hectare (988,400-acre) logging concession near the Brazilian border. Final approval hinges on the completion of an environmental impact survey and a tree inventory. While Simon & Shock International says it plans to conduct selective logging, the firm has not announced whether it will seek Forest Stewardship Council certification, a mark for responsibly-harvested timber. Is there an alternative that can improve the lot for the average Guyanese? There may be. Last fall Guyana's President, Bharrat Jagdeo, hinted at the potential of using the country's forests as a giant carbon offset to counter climate change.

(02/20/2008) World fertilizer prices surged by more than 200 percent in 2007, as farmers sought to maximize corn production for ethanol, according to the International Center for Soil Fertility and Agricultural Development (IFDC). Poor African farmers were hardest hit by the increase.
Global warming - not el Nino - drove severe Amazon drought in 2005
(02/20/2008) One of the worst droughts on record in the Amazon was caused by high temperatures in the Atlantic rather than el Nino.

Amid accusations of bribery by loggers, Borneo chief's remains to be exhumed
(02/19/2008) Police have announced that they plan to exhume the body of Kelesau Naan to discover the cause of death. The Penan chieftain and passionate activist against logging disappeared in October while checking animal traps. His body was found on December 12th of last year. Several bones were broken, leading some to believe that Naan was assassinated because of his longtime work against loggers. Kelesau Naan had been one of the key figures in the Penan community's fight against logging. He was also a plaintiff and witness in a land rights claim that has been awaiting trial since 1998.

Mysteries of the Great White Shark unveiled
(02/17/2008) The Great White Shark has always been a creature of mystery. The world's largest shark has long fascinated humanity from the novel and film Jaws to recent sumptuous footage of the sharks catching sea lions in Planet Earth. The behemoth, who at times can reach seven meters in length, has also become famous for occasionally attacking swimmers and surfers, though scientists believe the sharks do not intentionally hunt humans. However, the great predator's behvaior and lifecycle remains mostly mysterious to science. Some of these mysteries are just now being unraveled thanks to the Tagging of Pacific Predators (TOPP) program.
Digital maps and mathematical analysis could reduce fishing bycatch
(02/16/2008) Images of dolphins and turtles ensnared in tuna nets are a heart-wrenching reminder of the impact of fisheries on ocean bio-diversity. Known in fisheries science as ‘by-catch,' this killing of non-target species is a complex problem that has resisted easy answers.
Past greenhouse warming events offer clues on future climate change
(02/16/2008) If carbon dioxide emissions from the burning of fossil fuels continue on a "business-as-usual" trajectory, humans will have added about 5 trillion metric tons of carbon to the atmosphere by the year 2400. A similarly massive release of carbon accompanied an extreme period of global warming 55 million years ago known as the Paleocene-Eocene Thermal Maximum (PETM).
