Indonesia's peatlands may offer U.S. firms global warming offsets
(08/29/2007) The following is modified version of a letter I've used to pitch U.S. companies on the concept of carbon finance in Indonesia's peatlands. Discussions are slow and the critical December U.N. climate meeting is fast approaching, so I'm posting this as a tool to help you get American firms interested in avoided deforestation offsets. Please feel free to use, modify, and distribute this letter widely.
How private equity can profit from carbon offsets in Indonesia
(08/29/2007) The emerging carbon market for avoided deforestation presents unprecedented opportunities for private equity to make profitable investments that also help protect the environment. Indeed, for the first time, conservation may be associated with positive financial returns. Here's a brief look at how private equity and other investors can capitalize on this opportunity to earn attractive returns while fighting climate change, protecting ecosystem services, and safeguarding endangered species like orangutans.
Greenhouse gases made 2006 2nd-warmest year on record for U.S.

European blood-sucker falls victim to global warming
(08/26/2007) Europe's only known land leech may be on the brink of extinction due to shifts in climate, report researchers writing in the journal Naturwissenschaften. The findings are significant because they suggest that "human-induced climate change without apparent habitat destruction can lead to the extinction of populations of cold-adapted species that have a low colonization ability," according to the authors.
Iron boosts carbon sequestration by the ocean
(08/23/2007) Wind-blown iron contributes significantly to the biological productivity of the Southern Ocean near Antarctica, researchers report in this week's issue of the journal Science.
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.
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.
Could a hurricane hit California?
(08/20/2007) San Diego has been hit by hurricanes in the past and could be affected by such storms in the future according to data from the National Oceanic and Atmospheric Administration (NOAA). While a hurricane in San Diego would likely produce significantly less damage than Hurricane Katrina in New Orleans, it could still exact a high cost to Southern California especially if the region was caught off guard.

(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.
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.
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.
U.S. government weather agency cuts hurricane outlook
(08/10/2007) The U.S. National Oceanic and Atmospheric Administration on Thursday reduced its forecast for the number of tropical storms and hurricanes expected during the 2007 Atlantic season. NOAA said it now expected between 13 and 16 named storms, with seven to nine becoming hurricanes and three to five of them classified as "major" hurricanes (categories 3, 4, or 5).
Global warming will slow, then accelerate reports ground-breaking model
(08/09/2007) Global warming will slow during the next few years but then accelerate with at least half of the years after 2009 warmer than 1998, the warmest year on record, reports a new study that is the first to incorporate information about the actual state of the ocean and the atmosphere, rather than the approximate ones most models use. The research, published by a team of scientists from the Hadley Center in the United Kingdom, appears in the current issue of the journal Science.

Careless humanity batters the Arctic
(07/03/2007) I feel the need to say from the outset when I discuss topics such as Global-Warming that I am indeed a greenie of sorts, and I believe that the obvious downward spiral that our planet is taking is due to the careless attitudes towards the environment that the industrialized and predominantly white nations have taken over the past decades. I, as a note, am white, and have no qualms in pointing the finger at my own country (Australia) and others that we support, and that support us. In fact, I am ashamed to be one of the only two countries in the world not to have signed the Kyoto Protocol (the other, for reference, being the United States of America).
China to ban ozone-depleting CFCs
(06/28/2007) China has moved to ban the production of ozone-depleting chlorofluorocarbons (CFCs), according to a statement from the country's environmental protection agency. The action is in accordance with the 1987 Montreal Protocol to phase out the use of ozone layer-depleting products . China, which signed the agreement in 1991, says it will end all CFC production by 2010.
Industrialized countries outsource CO2 emissions to China
(06/22/2007) Facing criticism as it surpasses the U.S. as the world's largest producer of carbon dioxide, China says that industrialized countries are hypocritical for criticizing its greenhouse gas emissions while buying its products, according to the Associated Press. China argues that developed countries are effectively outsourcing emissions by shifting manufacturing to its factories.

U.S. refuses to talk global warming cuts at G8 summit
(06/06/2007) President Bush said he opposed setting firm targets for greenhouse gas cuts at a G8 summit but said that his proposal to fight climate change would not undermine U.N. efforts, as critics have claimed.
Can cattle ranchers and soy farmers save the Amazon?
(06/06/2007) John Cain Carter, a Texas rancher who moved to the heart of the Amazon 11 years ago and founded what is perhaps the most innovative organization working in the Amazon, Alianca da Terra, believes the only way to save the Amazon is through the market. Carter says that by giving producers incentives to reduce their impact on the forest, the market can succeed where conservation efforts have failed. What is most remarkable about Alianca's system is that it has the potential to be applied to any commodity anywhere in the world. That means palm oil in Borneo could be certified just as easily as sugar cane in Brazil or sheep in New Zealand. By addressing the supply chain, tracing agricultural products back to the specific fields where they were produced, the system offers perhaps the best market-based solution to combating deforestation. Combining these approaches with large-scale land conservation and scientific research offers what may be the best hope for saving the Amazon.

China Unveils Global Warming Initiative
(06/05/2007) Scientists documented 467 species, including 24 species believed new to science, during a rainforest survey in eastern Suriname, South America. The expedition, led by conservation International (CI), was sponsored by two mining companies, BHP-Billiton Maatschappij Suriname (BMS) and Suriname Aluminium Company LLC (Suralco), hoping to mine the area for bauxite, the raw material used to make aluminum. conservation International said the Rapid Assessment Survey (RAP) will help "give miners guidance on protecting unique plants and animals during potential future development," according to a statement from the organization.
10-20% of birds extinct by 2100 due to global warming, deforestation
(06/04/2007) Ten to twenty percent of the world's terrestrial bird species could be threatened with extinction by 2100 due to climate change and habitat destruction reports a study published in the June 5 issue of the journal PLoS Biology. The numbers are in line with estimates published last year in The Proceedings of the National Academy of Sciences. Combining future projections on global warming, agricultural expansion and human population growth from the global Millennium Ecosystem Assessment with current geographic ranges of the world's 8,750 species of terrestrial birds, researchers Walter Jetz, David Wilcove, and Andrew Dobson estimate that 950 to 1800 species may be condemned to extinction by 2100.
Geoengineering could stop global warming but carries big risks
(06/04/2007) Using radical techniques to ,engineer, Earth's climate by blocking sunlight could cool Earth but presents great risks that could well worsen global warming should they fail or be discontinued, reports a new study published in the June 4 early online edition of The Proceedings of the National Academy of Sciences.
Globalization could save the Amazon rainforest
(06/03/2007) The Amazon basin is home to the world's largest rainforest, an ecosystem that supports perhaps 30 percent of the world's terrestrial species, stores vast amounts of carbon, and exerts considerable influence on global weather patterns and climate. Few would dispute that it is one of the planet's most important landscapes. Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change. Few people understand these impacts better than Dr. Daniel Nepstad, one of the world's foremost experts on the Amazon rainforest. Now head of the Woods Hole Research Center's Amazon program in Belem, Brazil, Nepstad has spent more than 23 years in the Amazon, studying subjects ranging from forest fires and forest management policy to sustainable development. Nepstad says the Amazon is presently at a point unlike any he's ever seen, one where there are unparalleled risks and opportunities. While he's hopeful about some of the trends, he knows the Amazon faces difficult and immediate challenges.
