Reducing tropical deforestation will help fight global warming
(05/10/2007) Scientists have lent support to a plan by developing countries to fight global warming by reducing deforestation rates. Tropical deforestation releases more than 1.5 billion metric tons of carbon into the atmosphere every year, though in some years, like the 1997-1998 el Nino year when fires released some 2 billion tons of carbon from peat swamps alone in Indonesia, emissions are more than twice that. Writing in the journal Science, an international team of scientists argue that the Reducing Emissions from Deforestation (RED) initiative, launched in 2005 by the United Nations Framework Convention on Climate Change, is scientifically and technologically sound, and that political and economic challenges facing the plan can be overcome.
Global carbon cycle is key to understanding climate change
(05/09/2007) Despite its importance to mankind, the global carbon cycle is poorly understood. With concerns over climate change mounting, it becomes all the more imperative to understand how carbon is absorbed by the Earth's oceans, vegetation, and atmosphere.
China finds 7.5 billion barrel oilfield
(05/08/2007) PetroChina, Asia's largest oil and gas producer, announced the discovery of a 7.5 billion barrel oil field off the northeast coast of China. The find, in an undersea field in Bohai Bay, is the largest in Asia in four decades and will boost China's known oil reserves by 20 percent. Nevertheless, the discovery will not be enough to offset China's oil imports, which have surged in recent years due to a booming economy and rapid adoption of automobiles.
Amazon rainforest locks up 11 years of CO2 emissions
(05/08/2007) The amount and distribution of above ground biomass (or the amount of carbon contained in vegetation) in the Amazon basin is largely unknown, making it difficult to estimate how much carbon dioxide is produced through deforestation and how much is sequestered through forest regrowth. To address this uncertainty, a team of scientists from Caltech, the Woods Hole Institute, and INPE (Brazil's space agency), have developed a new method to determine forest biomass using remote sensing and field plot measurements. The researchers say the work will help them better understand the role of Amazon rainforest in global climate change.

Peatlands store 100 years of CO2 emissions
(05/08/2007) The UN Convention on Climate Change is putting global climate at risk by ignoring carbon dioxide emissions from the destruction of carbon-rich peatlands in Indonesia, charged Wetlands International, a Dutch environmental group that has highlighted the climate impact of land-use change in southeast Asia.
U.S. could offset 20% of emissions through reforestation of marginal lands
(05/03/2007) Reforesting marginal agricultural land could significantly slow the increase of carbon in the atmosphere reports a new study based on NASA data, though it would be no magic bullet in fighting global warming since temperate forests have been shown to increase regional temperatures by absorbing more sunlight. Still, reforestation has the potential to offer other ancillary benefits including watershed services and erosion control.
U.S. and China fight plan to slow global warming
(04/30/2007) Claiming that costs of fighting global warming will be higher than consensus estimates, China and the United States are fighting plans to slow climate change, according to the Associated Press (AP). The countries also say the impacts of climate change will not be as severe as projected and want to raise the emissions cap of atmospheric carbon dioxide levels from 430 parts per million (ppm) proposed by the European Union to 445 ppm. Current CO2 levels stand around 381 ppm.
Dutch plan restricts biofuels that damage environment
(04/29/2007) The Netherlands has proposed a system to reduce the environmental impact of biofuels production. The country becomes the first in the world to establish such guidelines. Environmentalists have expressed increasing concern for the establishment of energy crops in biodiverse and carbon-rich ecosystems like the peatlands of Indonesia and the Amazon rainforest. They say that conversion of these forests for oil palm and soybeans is threatening endangered species and worsening global warming. Further, they warn, demand for such biomass energy products is driving up prices for food crops.
Dutch will demand rainforest-friendly palm oil
(04/27/2007) In a report scheduled to be released today, the Dutch government will outline criteria for growing biofuels in a more sustainable manner.

Lovins, cofounder and CEO of the Colorado-based Rocky Mountain Institute, speaking at Stanford University Wednesday night for a week-long evening series of lectures sponsored by Mineral Acquisition Partners, Inc.
Some corals may survive acidification caused by rising CO2 levels
(03/29/2007) Several studies have shown that increased atmospheric carbon dioxide levels are acidifying the world's oceans. This is significant for coral reefs because acidification strips carbonate ions from seawater, making it more difficult for corals to build the calcium carbonate skeletons that serve as their structural basis. Research has shown that many species of coral, as well as other marine microorganisms, fare quite poorly under the increasingly acidic conditions forecast by some models. However, the news may not be bad for all types of corals. A study published in the March 30 issue of the journal Science, suggests that some corals may weather acidification better than others.
Non-CO2 gases also cause global warming
(03/29/2007) While most of the focus in developing a policy to fight global warming has been on carbon dioxide, other gases also contribute to climate change. The effect of these gases is still poorly understood and should be the subject of further research say two climate scientists writing in the March 30 issue of the journal Science.
