Blocking sunlight may cripple toxic bacteria

(08/23/2007) Certain types of bacteria have sunlight-sensing molecules similar to those found in plants, according to a new study. Surprisingly, at least one species--responsible for causing the flu-like disorder Brucellosis--needs light to maximize its virulence. The work suggests an entirely new model for bacterial virulence based on light sensitivity.

U.S. firms driving pollution in China

(08/22/2007) U.S. firms are helping drive environmental degradation in China, putting the health of millions of Chinese at risk, reports The Wall Street Journal. The paper says that by demanding ever lower products for goods, manufacturers are forced to reduced environmental safeguards in order to compete.


Could peatlands conservation be more profitable than palm oil?

(08/22/2007) This past June, World Bank published a report warning that climate change presents serious risks to Indonesia, including the possibility of losing 2,000 islands as sea levels rise. While this scenario is dire, proposed mechanisms for addressing climate change, notably carbon credits through avoided deforestation, offer a unique opportunity for Indonesia to strengthen its economy while demonstrating worldwide innovative political and environmental leadership. In a July 29th editorial we argued that in some cases, preserving ecosystems for carbon credits could be more valuable than conversion for oil palm plantations, providing higher tax revenue for the Indonesian treasury while at the same time offering attractive economic returns for investors.


U.S. military attacks illegal wildlife trade in Afghanistan

Court rebukes Bush Administration on global warming report

(08/22/2007) Tuesday the Bush Administration was ordered to publish an updated research plan and national assessment on climate change. By law the White Hosue is required to publish such a report every four years, yet the current administration has failed to do so since it took office. The last National Assessment was issued in late 2000 under the Clinton administration, but environmental groups say the Bush Administration had tried to surpress its findings and recommendations.

Clearing rainforest for cattle pasture drives surge in vampires

(08/15/2007) A new study confirms that vampire bats are thriving due to the clearing of rainforest for cattle pasture in Costa Rica. Instead of having to seek out scarce wildlife in the forest, vampire bats now prey on cattle kept in high densities on ranches.


Emerging (disease) markets

(08/15/2007) Instead of attacking wild birds for our new disease problems, a far more cost effective approach should focus on keeping wild animals separate in the places where they often commingle: in wildlife markets and international trade, according to wildlife health experts from the Wildlife conservation Society (WCS) and the United Nations' Food and Agriculture Organization (FAO) in a recent issue of the prestigious Journal of Wildlife Diseases.

conservation more effective than biofuels for fighting global warming

(08/15/2007) Conserving forests and grasslands may be a more effective land-use strategy for fighting climate change than growing biofuel crops argues a new paper published in the journal Science. Comparing emissions from various fuel crops versus carbon storage in natural ecosystems, Renton Righelato and Dominick Spracklen write that "forestation of an equivalent area of land would sequester two to nine times more carbon over a 30-year period than the emissions avoided by the use of the biofuel."


Earthquakes can break speed limit

(08/15/2007) Earthquakes can move faster than previously thought with rupture rates well exceeding the conventional 3 kilometeres per second, reports Oxford University professor Shamita Das writing in the journal Science. The finding suggests that earthquakes in the world's largest quake zones may be capable of more destruction than earlier projections.

(08/14/2007) Waves from the devastating December 2004 tsunami were recorded along the Atlantic coast of North America, reports a new study published in Geophysical Research Letters.


Legless lizard retracts eyes to avoid retaliatory prey bites

(08/14/2007) For creatures without legs, snakes are remarkable predators. Pythons can capture and eat animals well over twice their size, while a mere drop of venom injected by an Australian death adder can kill a person. Scientists believe the main purpose for these adaptations is to help snakes avoid injury when pursuing and eating prey. However, snakes are not the only legless reptiles -- there are more than a dozen species of legless lizard distributed around the world. A new paper examines how these reptiles subdue their prey without venom or constriction.


Squirrels communicate with rattlesnakes using heated tail

(08/13/2007) Ground squirrels heat their tails to defend their young against predatory rattlesnakes, reports a study published in the early online edition of Proceedings of the Natural Academy of Sciences (PNAS).


Failing water supply destroyed lost city of Angkor Wat

(08/13/2007) The ancient city of Angkor in Cambodia was larger in extent than previously thought and fed by a single water system, according to a new map published by an international team of researchers. The study, published in the early online edition of the journal Proceedings of the Natural Academy of Sciences, suggests that the urban settlement sustained an elaborate water management network extending over more than 1,0000 square kilometers.


New flycatcher bird species discovered in Peru

(08/13/2007) Scientists have discovered a previously unknown species of bird in dense bamboo thickets in the Peruvian Amazon.


Low deforestation countries to see least benefit from carbon trading

(08/13/2007) Countries that have done the best job protecting their tropical forests stand to gain the least from proposed incentives to combat global warming through carbon offsets, warns a new study published in Tuesday in the journal Public Library of Science Biology (PLoS). The authors say that "high forest cover with low rates of deforestation" (HFLD) nations "could become the most vulnerable targets for deforestation if the Kyoto Protocol and upcoming negotiations on carbon trading fail to include intact standing forest."


Amazon deforestation in Brazil falls 29% for 2007

(08/13/2007) Deforestation in the Brazilian Amazon fell 29 percent for the 2006-2007 year, compared with the prior period. The loss of 3,863 square miles (10,010 square kilometers) of rainforest was the lowest since the Brazilian government started tracking deforestation on a yearly basis in 1988.


Global warming to stunt growth of rainforest trees

(08/12/2007) A statement from the University of Alabama argues that a recent Newsweek cover story on climate change made two important mistakes.


Climate change claims a snail

(08/12/2007) The Aldabra banded snail (Rachistia aldabrae), a rare and poorly known species found only on Aldabra atoll in the Indian Ocean, has apparently gone extinct due to declining rainfall in its niche habitat. While some may question lamenting the loss of a lowly algae-feeding gastropod on some unheard of chain of tropical islands, its unheralded passing is nevertheless important for the simple reason that Rachistia aldabrae may be a pioneer. As climate change increasingly brings local and regional shifts in precipitation and temperature, other species are expected to follow in its path.


Controversy over flawed NASA climate data changes little

(08/11/2007) NASA corrected an error on its U.S. air temperature data after a blogger, Steve McIntyre of Climate Audit, discovered a discrepancy for the years 2000-2006. The revised figures show that 1934, not 1998, was America's hottest year on record. The change has little affect on global temperature records and the average temperatures for 2001-2006 (at 0.66 C) is still warmer than 1930-1934 (0.63 C) in the United States.


European heat waves double in length since 1880

(08/11/2007) The most accurate measures of European daily temperatures ever indicate that the length of heat waves on the continent has doubled and the frequency of extremely hot days has nearly tripled in the past century. The new data shows that many previous assessments of daily summer temperature change underestimated heat wave events in western Europe by approximately 30 percent.


Floods affect 500 million people per year, will worsen with warming

(08/10/2007) Floods affect 500 million people a year and cause billions of dollars in damage, said U.N. officials Thursday.

Papua seeks funds for fighting global warming through forest conservation

(08/10/2007) In an article published today in The Wall Street Journal, Tom Wright profiles the nascent "avoided deforestation" carbon offset market in Indonesia's Papua province. Barnabas Suebu, governor of the province which makes up nearly half the island of New Guinea, has teamed with an Australian millionaire, Dorjee Sun, to develop a carbon offset plan that would see companies in developing countries pay for forest preservation in order to earn carbon credits. Compliance would be monitored via satellite.
