Carbon stored in Canada's boreal forests and peatlands is worth $3.7 trillion according to research by the Pembina Institute for the Canadian Boreal Initiative. The two-year study puts the value of ecosystem services like water filtration, pest-control services, and carbon storage at $93 billion -- roughly 2.5 times greater than the net market value of forestry, hydroelectric, mining, and oil and gas extraction in Canada's Boreal region.

Two noteworthy climate change articles appeared in this week's Science. One reported that global ocean levels are rising twice as fast today as they were 150 years ago, based on core samples of sediments along the New Jersey coast. The other, using Antarctic ice cores, says that carbon dioxide levels are now 27 percent higher than at any point in the last 650,000 years. Finally, another article in Science announced the discovery of a musical iceberg in Antarctica.

Rising ocean levels will inundate low-lying islands and spawn environmental refugees says a Reuters article. Earlier this year the UN forcast that some 50 million people could became environmental refugees by 2010, driven from their homes by desertification, rising sea levels, flooding and storms linked to climate change.

Goldman Sachs became the first global investment bank to adopt a comprehensive environmental policy. The policy acknowledges the scientific consensus on climate change and calls for urgent action by public policy makers and federal regulators to reduce greenhouse gas emissions. The firm further agrees to promote green building standards and sustainable wood certification.

Britain is the biggest importer of illegally-logged timber in Europe, responsible for the destruction of 1.4 million acres of forest a year according to a new report by the World Wildlife Fund for Nature.

A week after a Brazilian environmentalist died after self-immolation in a protest against the construction of alcohol factories in the Pantanal marsh region, WWF called for the restructuring of a planned infrastructure project that threatens the sensitive ecosystem.

Fluorescent patches on the wings of African swallowtail butterflies work in a very similar, but more efficient way to high emission light emitting diodes (LEDs) used in electronic equipment and displays, according to University of Exeter research published in Science.

Fish are increasingly threatened by the effects of climate change as temperatures rise in rivers, lakes and oceans, says a new WWF report. It says that hotter water means less food, less offspring and even less oxygen for marine and freshwater fish populations. Meanwhile, a researcher in Australia said that freshwater ecosystems in that country will be threatened as much by the human response to climate change as by climate change itself.

Revised deforestation figures from FAO show that Nigeria, not Cambodia, suffered the highest rate of forest loss between 2000 and 2005. During that period, the West African country lost 55.7 percent of its primary forests, mostly due to logging, fuelwood collection, and subsistence agriculture. FAO gave no reason for the revision.

Developed countries, taken as a group, have cut greenhouse gas emissions 5.9% compared to the 1990 levels according to a new publication from the United Nations Climate Change secretariat. However the figures are misleading because of the large reduction in emissions from Eastern Europe, where the transition towards a market economy has shuttered many of the worst polluting industries.

Continued increases in greenhouse gas concentrations in the atmosphere from the combustion of fossil fuels could trigger large-scale changes in global biodiversity and require thousands of years of recovery according to recent research on an extreme global warming episode 55 million years ago.

The Food and Agriculture Organization of the United Nations today released its assessment of world's forests showing that some 13 million hectares of the world's forests -- an area the size of Panama -- are lost each year. FAO claims that forest loss has slowed since the 1990-2000 period, but analysis of the numbers shows that FAO is using industrial plantations to offset deforestation figures for natural forests. Further, many groups see the FAO figures as heavily flawed since they define forest as being an area with as little as 10% actual tree cover and rely on figures provided not by objective third party sources, but by governments that have incentives to manipulate forest cover numbers.

In the tropical forests of Guatemala, poor rural farmers and loggers are battling environmentalists, archaeologists, and Mel Gibson over the establishment of a 525,000-acre Mayan national park.

Researchers from the University of Zurich have named a newly discovered species of lemur after British comedian John Cleese in honor of his work with the primates from Madagascar.

The House leadership dropped its plan to allow oil drilling in the Arctic National Wildlife Refuge as part of the budget bill. 22 Republican Congressmen said they would vote against the budget if it meant drilling in the wildlife refuge.

A conference meeting in Nairobi, Kenya is seeking to establish stronger African science academies in an effort to build scientific expertise on the continent.

A coalition of conservation groups filed a complaint against the White House for delaying protection of hundreds of wildlife species as endangered under the Endangered Species Act, leaving 283 plants and animals on a perpetual candidate waiting list. According to the suit, since passage of the Act, at least 24 candidate species have gone extinct waiting for protection.

The International Energy Agency (EIA) released a report projecting that global greenhouse gas emissions will rise by 52% by 2030, unless the world takes action to reduce energy consumption. Further, the IEA says that oil prices will rise "substantially" unless there is extra investment -- $20.3 trillion in fresh facilities by 2030 -- in oil facilities.

Rabid vampire bats killed 23 people and attacked more than 1,000 Brazilian officials confirmed last week. The bats have been displaced from their normal rain forest environment by worsening deforestation in the region.

The Food and Agriculture Organization of the United Nations has issued a response to a study that found selective logging in the Amazon is highly destructive. The research, conducted by scientists from the Carnegie Institution at Stanford University, was published in Science last month. FAO argues that selective logging is not necessarily destructive and can be done with low impact on the remaining forests, if the proper techniques are applied.

The government of Papua New Guinea announced that it will create 12 new protected areas covering some of the country's most biologically diverse forests, wetlands and coral reefs. Currently only 2.7 per cent of the country's land area and 0.07 per cent of its territorial waters are included in protected areas -- one of the lowest figures of protected area cover of any country in the world.

Ebay Inc. founder Pierre Omidyar and his wife, Pamela, have given $100 million in eBay stock to Tufts University to create a fund that will invest in microfinance. Microfinance, the practice of loaning small amounts of money to people who are often too poor to qualify for conventional lending, is increasingly seen as a promising means to help the world's poorest people. Supporters argue that microfinance can fund microenterprises that generate broad-based, long-term economic growth opportunities in developing countries.

Researchers at Lawrence Livermore National Laboratory estimate that should fossil fuel consumption continue at its current pace, ocean sea levels will rise by more than 20 feet (seven meters) and median air temperatures will increase 14.5 degrees.

The economic benefits of protecting a rainforest reserve outweigh the costs of preserving it says a new study published in Proceedings of the National Academy of Sciences. A cost-benefit analysis of Mabira Forest Reserve in southern Uganda found that rainforest conservation was economically viable despite intense pressures to exploit the forest for timber harvesting, fuelwood, charcoal production, and agricultural development. The research suggests rainforest parks can play an important economic role in rural communities.
November 1, 2005
Research released earlier this month in Science found that Brazil's Amazon rain forest is being degraded twice as fast as deforestation figures suggest. Selective logging, where only one or two valuable tree species are harvested from an area, is driving the forest degradation. The findings have important implications for "sustainable harvesting" schemes that have been promoted as ecologically-sound alternatives to traditional harvesting techniques.
