Clean Development Mechanism - An Important Tool to Reduce GHG Emissions
(10/26/2008) The Clean Development Mechanism (CDM), is a mechanism under the Kyoto Protocol for promoting technology transfer and investment from industrialized countries to the developing world for projects focussed on mitigating emissions of greenhouse gases. It provides for industrialized countries to invest in emission-reducing projects in developing countries and to use the resulting Certified Emissions Reductions (CER) credits towards their own compliance with the emission limitation targets set forth by the Kyoto Protocol.
Geoengineering schemes need ranking system to avoid wasting money, destroying the planet
(10/26/2008) Schemes to alter Earth's climate on a planetary scale should be ranked according to their efficacy, cost, risks and their rate of mitigation, argues a new editorial published in Nature Geoscience. With so-called geoengineering proposals proliferating as concerns over climate change mount, Philip Boyd of New Zealand's NIWA warns that "no geo-engineering proposal has been tested or even subjected to preliminary trials". He says that despite widespread media attention, scientists have yet to even come up with a way to rank geoegineering schemes for their efficacy, cost, associated risk, and timeframe. Thus is it unclear whether ideas like carbon burial, geochemical carbon capture, atmospheric carbon capture, ocean fertilization, cloud manipulation, "space sunshades", or strategically-placed pollution can be effective on a time-scale relevant to humankind, economical, or even safe.
Solar cells, flat-panel screens are source of potent greenhouse gas
(10/23/2008) Atmospheric concentrations of nitrogen trifluoride — a gas used in the manufacture of liquid crystal flat-panel displays, thin-film photovoltaic cells and microcircuits — are at least four times higher than previously estimated, reports a new study published in the journal Geophysical Research Letters.
Despite financial crunch, donors pledge $100M for rainforest conservation
(10/23/2008) Donors meeting this week in Washington D.C. pledged more than $100 million to the World Bank's new initiative for conserving tropical forests. In addition to the $100 million in donations, the World Bank announced that more than forty developing countries have asked to join the Forest Carbon Partnership Facility — the Bank's foray into the emerging market for forest carbon credits. 25 countries have so far been selected to participate in the initiative, which builds capacity for countries to earn compensation through the carbon markets for reducing greenhouse gas emissions by reducing deforestation and forest degradation (REDD). Experts say the mechanism could eventually lead to the transfer of billions of dollars per year to fund conservation and rural development in tropical countries, while at the same time helping fight climate change. Deforestation and land use change presently accounts for around a fifth of anthropogenic emissions.
EU says emissions trading system may fund forest conservation
(10/17/2008) Europe's carbon trading scheme may be used to generate funds to fight deforestation, reports Reuters. Speaking at a news conference on Friday, EU Environment Commissioner Stavros Dimas said he hoped the EU's emissions trading scheme could reduce gross tropical deforestation by half by 2020 and eliminate net forest loss by 2030.
Carbon conservation schemes will fail without forest people
(10/16/2008) Mechanisms that use forest conservation to reduce greenhouse gas emissions are doomed to fail unless they are "based on respect for the rights of indigenous peoples and forest communities," warn environmentalists and indigenous rights groups meeting in Oslo this week. Indigenous groups fear they are being excluded from discussions on Reduced Emissions from Deforestation and Forest Degradation (REDD), a proposed financial mechanism that would compensate tropical countries for reducing emissions caused by deforestation and land use. Such emissions account for a fifth of the global total, or more than the total emissions from transportation. In particular, indigenous groups and forest communities are concerned they will not see benefits from REDD. Worse, some believe the mechanism could trigger a new wave of land grabs and evictions by parties seeking to capitalize on carbon payments. Indigenous groups and forest communities have long struggled against development interests seeking to exploit their traditional lands and resources. But supporters of so-called "avoided deforestation" schemes say that properly-designed policy offers unprecedented opportunities to create sustainable livelihoods for forest people while safeguarding biodiversity and services provided by healthy forest ecosystems.
UK government: rainforests are weapon against global warming
(10/15/2008) Protecting tropical forests will simultaneously reduce carbon emissions, support poverty reduction and help preserve biodiversity and other forest services, says a new report commissioned by the British government. The report — dubbed the "Eliasch Review" after the lead author, Johan Eliasch, a multimillionaire Swede who runs a sports equipment company and owns 162,000 hectares (400,000 acres) of rainforest in the Brazilian Amazon — takes a comprehensive look at the role forests can play in mitigating climate change. It concludes: "Urgent action to tackle the loss of global forests needs to be a central part of any future international deal on climate change"

US government: $28 carbon price would raise gas prices by 25 cents
(10/08/2008) A national carbon price under a cap-and-trade system would have a limited impact on gasoline prices, reports a new study by the Congressional Budget Office (CBO). The report estimates that a carbon price of $28 per ton — a bit less than current carbon prices in the European market — would boost gas prices by 25 cents per gallon, while a $200 per ton tax would increase prices by less then $2. The findings suggest that the cost of climate change legislation may be lower than claimed by industry, but also indicate that efforts to curb Americans' driving habitats via a carbon tax or cap-and-trade scheme may be of limited effectiveness. A $2 increase in the price of gas would still leave U.S. fuel prices well below those in most of the world.
Al Gore calls for “civil disobedience” against new coal plants

Earth already committed to 2.4-degree C rise from climate change
(09/15/2008) As of 2005 the Earth was already committed to rise of global mean temperatures by 2.4°C (4.3°F), concludes a new study published in the journal Proceedings of the National Academy of Sciences (PNAS). The conclusion is significant because the Intergovernmental Panel on Climate Change (IPCC) has warned that a rise in global temperature by 1 to 3°C will lead to catastrophic consequences, including “widespread loss of biodiversity, widespread deglaciation of the Greenland Ice Sheet, and a major reduction of area and volume of Hindu-Kush-Himalaya-Tibetan glaciers, which provide the head-waters for most major river systems of Asia.” These glaciers, predicted to shrink considerably in the next few decades, provide food and water to over two billion people.

Old growth forests are giant carbon sinks, helping offset emissions
(09/11/2008) Old growth forests are important carbon sinks that help global warming, reports a study published in the journal Nature. The results run counter to claims by the forestry industry that old growth forests are carbon neutral or even net emitters of carbon dioxide.
Did prehistoric farmers drive early global warming?
(09/03/2008) In 2003 William Ruddiman put forth a controversial theory: 7,000 years ago the rise of agriculture spawned large-scale climatic changes. According to Ruddiman, the felling of forests for fields throughout Europe and Asia caused a rise in carbon dioxide, while the flooded fields for rice released methane gas. This combination of large amounts of carbon dioxide and methane entering the atmosphere caused the globe to warm, preventing the planet from entering another ice age.
Melting permafrost will be major driver of global warming
(09/01/2008) The thawing of permafrost in northern latitudes will become a major source of greenhouse gas emissions, according to a new study that more than doubles previous estimates of the amount of carbon stored in the frozen soils of Alaska and Siberia.
Past decade is warmest in at least 1300 years

Reduced impact logging can save 160 m tons of carbon emissions per year
(08/06/2008) Improving inefficient logging practices could significantly reduce greenhouse gas emissions from forest degradation, argues a new study published in the open-access journal PLoS.
Biofuels can reduce emissions, but not when grown in place of rainforests
(07/22/2008) Biofuels meant to help alleviate greenhouse gas emissions may be in fact contributing to climate change when grown on converted tropical forest lands, warns a comprehensive study published earlier this month in the journal Environmental Research Letters. Analyzing the carbon debt for biofuel crops grown in ecosystems around the world, Holly Gibbs and colleagues report that "while expansion of biofuels into productive tropical ecosystems will always lead to net carbon emissions for decades to centuries... [expansion] into degraded or already cultivated land will provide almost immediate carbon savings." The results suggest that under the right conditions, biofuels could be part of the effort to reduce humanity's carbon footprint.
Destruction of wetlands worsens global warming
(07/20/2008) Destruction of wetland ecosystems will generate massive greenhouse gas emissions in coming years, warn experts convening at an international wetlands conference in Brazil.
Beyond high food prices, little to show for $11B/yr in biofuel support, says OECD report
(07/17/2008) Government support of biofuel production in rich countries is squandering vast amounts of amounts of money while exacerbating the global food crisis and failing to meaningfully curb greenhouse gas emissions and improve energy security, alleges a new report from the OECD, the club of industrialized nations.
Gore launches second campaign... for Earth
(07/17/2008) In a speech Thursday, Al Gore challenged the U.S. to generate 100 percent of its electricity from zero carbon emission sources within 10 years. Speaking at Washington's Constitution Hall, Gore said America's security, environmental and economic crises are all related, and that measures to rein in greenhouse gas emissions will make the U.S. stronger, safer, and cleaner. "The survival of the United States of America as we know it is at risk," Gore said. "I don't remember a time in our country when so many things seemed to be going so wrong simultaneously."
First carbon map of America released by NASA
(07/15/2008) For the first time, one can have a whole view of America's carbon output: region by region, city by city. The Vulcan Project has undertaken a holistic inventory—including electricity, heat, transportation, and industry—of local carbon emissions across the nation to create the first carbon map of America. Texas leads the fifty states, and the county of Harris, Texas (encompassing Houston) records the nation's largest emissions by county. Although Texas is second in population after California, its massive industry puts it over the top.
Pine beetles attack Canada, boosting GHG emissions
(07/10/2008) The mountain pine beetle, a small tree-devouring insect, has deforested an area of British Columbia the size of Louisiana — over 130,000 square kilometers. The 5 millimeter insect is a perfect tree-destroying machine. The beetles bore through the tree's bark to reach the phloem of the tree, which contains the tree's organic nutrients. The beetles then feed on these nutrients and lay their eggs. The trees defend themselves by secreting extra resin, but the beetles are often able to combat this by releasing a blue fungi. In about two weeks time, the tree turns a tell-tale red and essentially starves to death. The mountain pine beetles move on.
Britain urges 'cautious approach' on biofuels
(07/07/2008) Britain and the E.U. should exercise caution in pushing for wider use of biofuels, warns a new study commissioned by the U.K. government.
CO2 emissions could doom fishing industry
(07/03/2008) Aside from warming climate, rising carbon dioxide emissions are contributing to ocean acidification, threatening sea live, warn researchers writing in the journal Science. This trend makes it all the more important to reduce emissions, argue the authors.
California plan would cut emissions 30% by 2020
(06/27/2008) California announced a plan to reduce state greenhouse gas emissions by 30 percent by 2020.
The Importance of Immediate Action for Climate Mitigation
(06/27/2008) Speed matters for successfully managing the transition to a low-carbon future. We need to start now with immediate mitigation to learn what works best to limit climate emissions and enhance sinks, and to build confidence to strengthen efforts in the future. Immediate mitigation also is essential for getting ahead of accelerating climate feedbacks by quickly reducing greenhouse gas concentrations from the current 385 ppm (growing fast at 2 ppm/year) to a safe level — perhaps as low as 350 ppm.
China's CO2 emissions 14% higher than America's in 2007
(06/14/2008) China emitted 14 percent more carbon dioxide than the United States in 2007 according to a report released by the Netherlands Environmental Assessment Agency. China's emissions grew 8 percent from 2006.

Carbon dioxide, methane levels rise sharply in 2007
(04/23/2008) Atmospheric concentrations of carbon dioxide and methane rose sharply in 2007, according to NOAA. The U.S. weather agency said that global levels of atmospheric carbon dioxide, the primary driver of global climate change, climbed by 0.6 percent, or 19 billion tons in 2007. Methane levels increased by 27 million tons after nearly a decade with little or no increase.
Gore to spend $300 million on global warming ads
(03/31/2008) This week Al Gore will launch a three-year, $300 million campaign to mobilize support for reining in greenhouse gas emissions, reports The Washington Post.
Asia Pulp & Paper destroying rare Sumatra forest
(03/27/2008) Companies linked to timber giant Asia Pulp & Paper (APP) are illegally building a road that runs through highly endangered peatland forest on the island of Sumatra, according to an investigative report published by Eyes on the Forest, a coalition of NGOs in Indonesia. The road would allow APP and its affiliates to log forests for timber and drain peat soil for the establishment of oil palm plantations. The action would release large amounts of carbon dioxide into the atmosphere from one of the world's largest contiguous tropical peat swamp forests.
China's emissions growth 2-4 times greater than expected
(03/11/2008) China's carbon dioxide emissions are growing far faster than anticipated according to according to a new analysis by economists at the University of California, Berkeley, and the University of California, San Diego. The study, published in the Journal of Environmental Economics and Management, estimates China will see an 11 percent annual growth rate in CO2 emissions between 2004 and 2010, two to four times the 2.5 to 5 percent growth rate estimated by the Intergovernmental Panel on Climate Change.
Emissions from deforestation offset by increased tree growth in the Amazon
(03/10/2008) An increase in carbon sequestration by trees in the Amazon has roughly offset total emissions from deforestation in the region since the 1980s. A new study, published in Philosophical Transactions of the Royal Society B, this trend may slow in the future, causing the world's largest rainforest to become a net source of carbon emissions and therefore contributing to climate change.
