Green Campaign Dents Palm Oil Demand
October 1, 2007 09:20 AM - Reuters
KUALA LUMPUR - A campaign by environment groups against palm oil is costing the product market share in Europe, a top Malaysian palm oil industry official said on Monday. Palm oil, used as food and in products ranging from cosmetics to biofuel, has come under fire from environmentalists in Europe and America who say the rapid expansion in palm cultivation is responsible for vanishing tropical forests and wildlife.
Deforestation Needs to be in Next Climate Pact
October 1, 2007 09:08 AM - Reuters
JAKARTA -Cutting emissions from deforestation will be key to curbing climate change and should be agreed upon in December's climate talks in Bali, a leading Indonesian forestry researcher said on Monday. The conference on the resort island is expected to initiate talks on clinching a new deal by 2009 to fight global warming. Under the Kyoto Protocol, developed nations can pay poor countries to cut emissions from activities such as the manufacture of refrigerants and fertilizers as well as capturing greenhouse gases from farm waste and rubbish dumps.
Tropical Storm Juliette forms in Mexican Pacific
September 30, 2007 05:27 PM - Reuters
MEXICO CITY (Reuters) - Tropical Storm Juliette formed in the Pacific Ocean off Mexico and was forecast to whirl along off the Baja California peninsula over the next few days, the U.S. National Hurricane Center said on Sunday.
Juliette was carrying maximum sustained winds of 45 mph (72 kph) and was more than 350 miles southwest of the peninsula.
The center described Juliette as a "weaker storm" that could lose force as it hit cooler waters.
Greek forests severely damaged by summer fires

A report by WWF gives an overview of the damages and environmental impacts caused by the devastating wildfires that raged throughout southern Greece this past summer.
According to WWF-Greece, the wildfires scorched a total of 177,265 hectares in the Peloponese Peninsula south of Athens — 55% (97,518ha) of which consisted of forests and areas of natural vegetation, 41% (78,104ha) of agricultural land and 1% of infrastructure (settlements, roads, etc.).
Magnitude 7.4 quake hits near New Zealand
September 30, 2007 09:21 AM - Reuters
A strong earthquake with a magnitude of 7.4 hit some 500 km (300 miles) southwest of New Zealand on Sunday, but there were no reports of damage and authorities discounted the risk of a major tsunami.
The quake occurred at around 6:24 p.m. local time, and was felt throughout the south of New Zealand's South Island, said Warwick Smith of state agency GNS Science.
Wasp Study Suggests Altruism Evolved From Maternal Behavior
September 29, 2007 07:29 PM - Diana Yates, University of Illinois
CHAMPAIGN, Ill. — Researchers at the University of Illinois have used an innovative approach to reveal the molecular basis of altruistic behavior in wasps. The research team focused on the expression of behavior-related genes in Polistes metricus paper wasps, a species for which little genetic data was available when the study was begun. Their findings appear today online in Science Express.
Like honey bee workers, wasp workers give up their reproductive capabilities and focus entirely on nurturing their larval siblings, a practice that seems to defy the Darwinian prediction that a successful organism strives, above all else, to reproduce itself. Such behaviors are indicative of a eusocial society, in which some individuals lose, or sacrifice, their reproductive functions and instead work to benefit the larger group.
Increasing Atmospheric Moisture Tied To Human Activities
September 29, 2007 05:43 PM - Lawrence Livermore Laboratory
LIVERMORE, Calif. –Observations and climate model results confirm that human-induced warming of the planet is having a pronounced effect on the atmosphere’s total moisture content.
Those are the findings of a new study appearing in the Sept. 17 online edition of the Proceedings of the National Academy of Sciences.
“When you heat the planet, you increase the ability of the atmosphere to hold moisture,” said Benjamin Santer, lead author from Lawrence Livermore National Laboratory’s Program for Climate Modeling and Intercomparison. “The atmosphere’s water vapor content has increased by about 0.41 kilograms per square meter (kg/m²) per decade since 1988, and natural variability in climate just can’t explain this moisture change. The most plausible explanation is that it’s due to the human-caused increase in greenhouse gases.”
Study: Global Warming Effecting North America's Northernmost Arctic Lake
September 29, 2007 05:35 PM - Paul Schaefer, ENN
Quebec, Canada - Analyses conducted by researchers from Université Laval’s Center for Northern Studies reveal that aquatic life in Ward Hunt Lake, the continent’s northernmost lake, is affected by climate change.
Ward Hunt Lake is a body of water located on a small island north of Ellesmere Island in the Canadian Arctic, has undergone major transformations within the last two centuries. The speed and range of these transformations—unprecedented in the lake’s last 8,000 years—suggest that climate change related to human activity could be at the source of this phenomenon.
The researchers’ conclusions are based on the analysis of a sediment core extracted in the center of Ward Hunt Lake in August 2003. This 18 centimeter long sediment core containing algae pigments and diatom remnants was used by the researchers as a biological archive in order to determine the diversity and abundance of aquatic life-forms in the lake over the last 8,450 years.
Researchers Discover Tropical Kelp Forests
September 29, 2007 04:33 PM - Paul Schaefer, ENN
Santa Barbara, California - Santa Barbara, California - Researchers have discovered large undersea forests of endangered kelp in areas previously thought to be bare of the plant, in the tropics. Using a computer model, researchers believe they've located nearly 10,000 square miles of areas that could harbor the plant. "The ecosystems that form in these cold, deep pockets beneath warm tropical waters look more like their cousins in California than the tropical reefs just 200 feet above," said co-author Brian Kinlan, a researcher with UC Santa Barbara's Marine Science Institute. "It is very similar to what we see when we climb a high mountain. For example, high alpine country in California looks more like Alaska."
Little-known Indian tribe spotted in Peru's Amazon

LIMA (Reuters) - Ecologists have photographed a little-known nomadic tribe deep in Peru's Amazon, a sighting that could intensify debate about the presence of isolated Indians as oil firms line up to explore the jungle.
Carrying arrows and living in palm-leaf huts on the banks of the Las Piedras river, the tribe was glimpsed last week by researchers flying over the Alto Purus national park near the Brazilian border to look for illegal loggers.
"We saw them by chance. There were three huts and about 21 Indians -- children, women and young people," said Ricardo Hon, a forest scientist at the National Institute of Natural Resources.
