(07/17/2009) Temperate forests trump rainforests when it comes to storing carbon, reports a new assessment of global forest carbon stocks published July 14th in Proceedings of the National Academy of Sciences (PNAS). The findings have important implications for efforts to mitigate climate change by protecting forests. Sampling and reviewing published data from nearly 100 forest sites around the world, Heather Keith, Brendan G. Mackey, and David B. Lindenmayer of Australian National University found that Australia's temperate Eucalyptus forests are champions of carbon storage, sequestering up to 2,844 metric tons of carbon per hectare, a figure that far exceeds previous estimates. These forests, located in the Central Highlands of Victoria in southeastern Australia, are dominated by giant Mountain Ash (Eucalyptus regnans) trees, which can reach a height of 320 feet and live for more than 350 years. They are also favored by the timber industry. Mountain Ash forests have been widely logged across Australia, with only limited old-growth stands remaining.
Russia pledges to raise carbon emissions to combat global warming
(06/25/2009) In a bizarre announcement that threatens to further weaken the international community's ability to come together on climate change, Russia has said it will reduce its emissions 10-15 percent from 1990 levels by 2020. The problem is that in 1990 Russia's carbon emissions were much higher than they are today, so this 'lowering' of carbon emissions actually means that Russia will raise its emissions by 2 to 2.5 percent annually until 2020.
Wind could power the entire world
(06/22/2009) Wind power may be the key to a clean energy revolution: a new study in the Proceedings of the National Academy of Science finds that wind power could provide for the entire world’s current and future energy needs.
Fate of world's rainforests likely to be determined in next 2 years
(06/19/2009) The fate of millions of hectares of tropical forests will probably be sealed this year and next year, reports a new set of policy papers detailing an emerging climate change mitigation mechanism known as Reducing Emissions from Deforestation and Degradation (REDD). REDD has been proposed by the U.N. and other entities as a form of carbon finance under which industrialized nations would pay tropical countries for conserving their forest cover.
CO2 currently at highest level in 2.1 million years
(06/18/2009) Atmospheric carbon dioxide levels are higher than any point in the last 2.1 million years, report researchers writing in the journal Science.
REDD can compete financially with palm oil in Indonesia peatlands while protecting endangered species
(06/04/2009) A new paper by Oscar Venter, a PhD student at the University of Queensland, and colleagues finds that forest conservation via REDD — a proposed mechanism for compensating developing countries for Reducing Emissions from Deforestation and Degradation — could be economically competitive with oil palm production, a dominant driver of deforestation in Indonesia. The study, based on overlaying maps of proposed oil palm development with maps showing carbon-density and wildlife distribution in Kalimantan (Indonesian Borneo), estimates that REDD is financially competitive, and potentially able to fund forest conservation, with oil palm at carbon prices of $10-$33 per ton of carbon dioxide equivalent (tCO2e). In areas with low agricultural suitability and high forest carbon, notably peatlands, Venter and colleagues find that a carbon price of $2 per tCO2e would be sufficient to beat out returns from oil palm.
Peatlands conversion for oil palm a 'monumental mistake' for Indonesia's long-term prosperity, sustainability
(06/04/2009) Indonesia's decision earlier this year to allow conversion of up to 2 million hectares of peatlands for oil palm plantations is "a monumental mistake" for the country’s long-term economic prosperity and sustainability, argues an editorial published in the June issue of Frontiers in Ecology and the Environment.
U.S. CO2 emissions fall 2.8% in 2008
(05/21/2009) Carbon dioxide emissions from fossil fuel use in the United States fell 2.8 percent in 2008, the largest annual drop in more than 20 years, reports the Energy Information Administration. A slowing economy and high gasoline prices contributed to the decline. U.S. emissions from fossil fuel burning in 2008 were 15.9 percent above the 1990 level (the baseline for the 1997 Kyoto Protocol) and 2.8 percent below the 2005 level (the baseline proposed under the American Clean Energy and Security Act of 2009 [Waxman-Markey bill]).
Voluntary carbon markets double in 2008
(05/20/2009) Voluntary carbon markets greatly expanded in both transaction volume and value in 2008, providing critical funds for projects aiming to reduce greenhouse gas emissions, according to a new report from Ecosystem Marketplace and New Carbon Finance. Fortifying the Foundation: State of the Voluntary Carbon Markets 2009 — a survey of over 190 voluntary carbon credit retailers, brokers, accounting registries, and exchanges — found that voluntary carbon markets transacted 123 million metric tons of carbon credits valued at $705 million in 2008, up from 65 million tons of credits valued at $331 million in 2007.
Global warming estimates double in severity according to new MIT modeling
(05/20/2009) Employing the MIT Integrated Global System Model, scientists have found that global warming could be more than twice as severe as previous estimates six years ago. The MIT Integrated Global Systems Model, which uses computer simulations to analyze the relationship between climatic changes and the global economy, found during 400 runs of the model that there is a 90 percent probability that temperatures will have risen 3.5 to 7.4 degrees Celsius by the end of the century.
Obama to increase fuel economy standard to 35 mpg by 2016
(05/18/2009) The Obama administration will direct the Environmental Protection Agency (EPA) and the Department of Transportation to raise fuel economy standards of automobiles to 35 miles per gallon by 2016, four years earlier than required under current federal law, reports the Wall Street Journal. The move is part of the administration's effort to reduce greenhouse gas emissions. Transportation accounts for nearly one third of U.S. carbon dioxide emissions.
Tropical storms affect carbon sinks by knocking down forests
(04/27/2009) Studying nearly a hundred and fifty years of tropical storm landfalls in the United States, researchers have discovered that the storm systems have a sizeable impact on forest carbon sinks due to the large-scale destruction of trees.
Fire contributes 20% of global warming emissions
(04/23/2009) Fire accounts for roughly half of greenhouse gas emissions from deforestation and about twenty percent of total emissions from human activities, report researchers writing in the journal Science. The estimates — based on analysis of fire's impact on emissions of carbon dioxide, nitrous oxide, and methane; albedo or the reflectivity of Earth's surface; and release of aerosols and other particulates — suggest fire plays a major large role in climate than conventionally believed.
U.S. climate change legislation may cut energy costs - report
(04/21/2009) The U.S. can dramatically cut greenhouse gas emissions while reducing energy spending at the same time, reports a new study by the Union of Concerned Scientists (UCS).
EPA finds CO2 a danger to public health
(04/17/2009) The U.S. Environmental Protection Agency on Friday ruled that carbon dioxide and other greenhouse gases "may endanger public health or welfare", a finding that opens to door to future regulation of such emissions under the the Clean Air Act.
Cutting greenhouse gases now would save world from worst global warming scenarios
(04/14/2009) If nations worked together to produce large cuts in greenhouse gases, the world would be saved from global warming's worst-case-scenarios, according to a new study from the National Center for Atmospheric Research (NCAR). The study found that, although temperatures are set to rise this century, cutting greenhouse gases by 70 percent the globe could avoid the most dangerous aspects of climate change, including a drastic rise in sea level, melting of the Arctic sea ice, and large-scale changes in precipitation. In addition such cuts would eventually allow the climate to stabilize by the end of the century rather than a continuous rise in temperatures.
Rainforest conservation gains in U.S. and U.N. climate proposals
(04/14/2009) A proposed mechanism for reducing emissions from deforestation and degradation (REDD) figures prominently in the draft climate bill released last month by Congressmen Henry Waxman and Ed Markey as well as a U.N. document posted last week following a climate meeting in Bonn, Germany. Deforestation is the source of roughly 20 percent of greenhouse gas emissions from human activities.
Ocean fertilization will not help reduce CO2 levels, suggests experiment
(03/24/2009) A controversial 'ocean fertilization' experiment suggests seeding the seas with iron to boost carbon-absorbing phytoplantkon will not sequester much carbon dioxide from the atmosphere. Some — including researchers and private companies — had hoped iron fertilization might be an easy fix for climate change.
EPA takes first step towards regulating global warming emissions
(03/23/2009) The Obama Administration is reviewing a finding by the Environmental Protection Agency that carbon dioxide emissions — and associated impact on climate — are a danger to public health, reports the Associated Press.
Shells thinning due to ocean acidification
(03/13/2009) By soaking up excess CO2 from the atmosphere oceans are undergoing a rise in acidity which is having ramifications across their ecosystems, most frequently highlighted in the plight of coral reefs around the world. However, a new study in Nature Geoscience shows that the acidification is affecting another type of marine life. Foraminifera, a tiny amoeba-like entity numbering in the billions, have experienced a 30 to 35 percent drop in their shell-weight due to the high acidity of the oceans.
Drought threatens the Amazon rainforest as a carbon sink
(03/05/2009) Drought in the Amazon is imperiling the rainforest ecosystem and global climate, reports new research published in Science. Analyzing the impact of the severe Amazon drought of 2005, a team of 68 researchers across 13 countries found evidence that rainfall-starved tropical forests lose massive amounts of carbon due to reduced plant growth and dying trees. The 2005 drought — triggered by warming in the tropical North Atlantic rather than el Niño — resulted in a net flux of 5 billion tons of carbon dioxide (CO2) into the atmosphere — more than the combined annual emissions of Japan and Europe — relative to normal years when the Amazon is a net sink for 2 billion tons of CO2.
China's emissions rise 45%, but Western demand accounts for 30% of increase
(02/26/2009) Thirteen-and-a-half percent of China's 45 percent rise in greenhouse gas emissions between 2002 and 2005 can be attributed to export production for Western countries, reports a new study published in Geophysical Research Letters. In other words, outsourcing of manufacturing by American and European firms accounted for larger share of carbon dioxide emission growth than rising domestic consumption in China (which made of 7 percent of the figure). The results, which indicate that Western companies are effectively outsourcing emissions along with manufacturing, have implications for future climate treaties, says one of the authors.
Carbon dioxide monitoring satellite crashes immediately after launch
(02/24/2009) The Orbiting Carbon Observatory, a $273 million satellite that would have collected measurements of carbon dioxide (CO2) in Earth's atmosphere to help better forecast the climate impacts of changes in CO2 levels, crashed about three minutes after launch, reports NASA. Researchers say the accident is a major setback for science.
Clinton, Obama botch opportunity on climate, forest conservation
(02/20/2009) The Obama administration squandered a chance this week to show U.S. leadership on climate and forest conservation issues, when Secretary of State Hillary Clinton, during a visit to Jakarta, failed to bring up a new Indonesian government decree allowing conversion of carbon-rich peat forests to oil-palm plantations.
CO2 levels rise to a new record
(02/17/2009) Atmospheric carbon dioxide concentrations climbed 2.28 parts-per-million (ppm) in 2008 to the highest level in at least 650,000 years — and possibly 20 million years — reports NOAA.
Burning rainforests, melting tundra could accelerate global warming well beyond current projections
(02/16/2009) Projections by the Intergovernmental Panel on Climate Change (IPCC) likely underestimate the scale and rapidity of climate change, warned a Stanford University scientist presenting Saturday at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago.
Indonesia may allow conversion of peatlands for palm oil
(02/15/2009) The Indonesian government will allow developers to convert millions of hectares of land for oil palm plantations, reports The Jakarta Post. The decision threatens to undermine Indonesia's efforts to reduce greenhouse gas emissions from land use and fashion itself as a leader on the environment among tropical countries.
Nemo at risk from CO2 emissions? Ocean acidification may hurt baby fish
(02/02/2009) Increasing carbon dioxide concentrations in the atmosphere may have an unexpected impact on marine ecosystems: disorienting fish larvae. Research published in this week's issue of the Proceedings of the National Academy of Sciences (PNAS) found that ocean acidification disrupts the olfactory sense of clownfish larvae, making it difficult for the fish to find a habitat, which for clownfish is a sea anemone.
Beef drives 80% of Amazon deforestation
(01/29/2009) Nearly 80 percent of land deforested in the Amazon from 1996-2006 is now used for cattle pasture, according to new maps released today in a report by Greenpeace at the World Social Forum in Belem, Brazil. The report, Amazon Cattle Footprint: Mato Grosso: State of Destruction, confirms that cattle ranching is the primary driver of deforestation in Earth's largest rainforest: the Brazilian Amazon.
Biochar and reforestation may offer better global cooling potential than ocean fertilization
(01/28/2009) The first comprehensive assessment of the climate cooling potential of different geoengineering schemes has been conducted by researchers at the University of East Anglia (UEA). The results are published in the journal Atmospheric Chemistry and Physics Discussions
Carbon market collapse claims another casualty
(01/22/2009) A recent collapse in carbon prices has triggered CantorCO2e — a carbon broker — to scale back on new clean energy projects, reports Reuters.
Will 'peak oil' spur expanded coal use? And what does it mean for climate?
(12/19/2008) The world must phase out emissions from coal by 2030 to avert dangerous climate change, said scientists speaking at the annual meeting of the American Geophysical Union in San Francisco.
Peak coal to follow peak oil?
(12/19/2008) Governments have greatly overestimated global coal reserves according to estimates presented by a geologist at the annual meeting of the American Geophysical Union in San Francisco.
Observed sea level rise, ice melt far outpaces projections
(12/17/2008) Sea levels will rise faster than previously estimated due to rapid melting of glaciers and ice sheets, according to a U.S government report released at the annual meeting of the American Geophysical Union in San Francisco. The report, titled Abrupt Climate Change, incorporates research published since last year's Intergovernmental Panel on Climate Change (IPCC) report, which drew largely from studies dating up to 2006. Most significantly, Abrupt Climate Change suggests that IPCC estimates for future sea level rise (18-58 cm) are conservative, noting that recent observations on sea level rise and loss of sea ice are far outpacing previous projections.
Climate change, ocean acidification may doom jumbo squid
(12/15/2008) Ocean acidification — driven by rising carbon dioxide levels in the atmosphere — may hurt the Humboldt squid, report researchers writing in the journal Proceedings of the National Academy of Sciences.
Climate change will transform the chemical-makeup of the ocean
(12/11/2008) By studying the ocean’s past, scientists have discovered that climate change has a much larger affect on ocean chemistry than expected. The study, published in Science, reveals that 13 million years ago climate change significantly altered the chemical composition of the oceans. Such changes in the ocean’s chemical makeup today could have a great impact on marine life, already stressed by overfishing and pollution.
Finland, Sweden push for loophole that would drive destruction of peatlands around the world
(12/09/2008) Finland and Sweden are pushing for a loophole in the E.U.'s Renewable Energy Directive that would open up vast tracts of peatlands around the world to development for biofuels production. The move could have drastic consequences for climate and biodiversity, warns Wetlands International, an environmental group.
Drought and deforestation in southeast Asia linked to climate change
(12/09/2008) Researchers have linked drought and deforestation in southeast Asia to climate change. Analyzing six years of climate and fire data from satellites, Guido van der Werf and colleagues report that burning of rainforests and peatlands in Indonesia, Malaysia, and Papua New Guinea released an average of 128 million tons of carbon (470 million tons of carbon dioxide - CO2) per year between 2000 and 2006. Fire emissions showed highly variability during the period, but were greatest in dry years, such as those that occur during El Niño events. Borneo was the largest source of fire emissions during the period, averaging 74 million tons per year, followed by Sumatra, which showed a doubling in emissions between 2000 and 2006.
Bank of America will no longer finance mountaintop removal coal mining
(12/04/2008) Bank of America will phase out financing for companies that practice mountaintop removal coal mining, a destructive and controversial method of coal extraction, according to a statement from the banking giant. The policy comes the day after the Environmental Protection Agency — at the behest of the Bush administration — approved a rule that will make it easier for coal companies to dump waste from mountaintop removal mining operations into streams and valleys.
Germany meets Kyoto target for CO2 emissions
(11/28/2008) Germany has reduced its carbon dioxide emissions below levels mandated under the Kyoto Protocol reports Bloomberg.
Tropical ocean dead zones could increase 50 percent by 2050
(11/18/2008) If carbon dioxide levels continue to rise as expected, marine dead zones in the tropics are expected to increase by 50 percent in just over four decades, according to a new study from the Leibniz Institute of Marine Sciences in Germany. The expansion of marine dead zones in tropical seas could have devastating impacts on ocean ecosystems and fisheries.
Water vapor will amplify global warming
(11/17/2008) The heat-amplifying effect of water vapor in the atmosphere could more than double the climate warming caused by increased carbon dioxide levels, report researchers using NASA data.
Industrialized countries slow to reduce emissions
(11/17/2008) Industrialized countries are making slow progress in reducing emissions as pledged under the Kyoto Protocol, finds a new U.N. assessment of global emissions.
CO2 emissions penalties may cost 20 countries $46 billion
(11/16/2008) Japan, Australia, and several European countries face billions of dollars in emissions penalties under the Kyoto Protocol, reports Bloomberg.
Group may sue EPA under Clean Water Act to address ocean acidification
(11/14/2008) An environmental group plans to sue the U.S. Environmental Protection Agency for failing to uphold water standards in the face of ocean acidification.
Limiting global warming to 2-degree rise will require $180/t carbon price says energy think tank
(11/13/2008) In a report released Wednesday the International Energy Agency warned that a business-as-usual approach to energy use would result in a 6°-degree rise in temperatures putting hundreds of millions at risk from reduced water supplies and diminished agricultural production. But the agency said that limiting temperature rise to 2-3°-rise by the end of the century would be "possible, but very hard."
Stopping ocean acidification would save billions of dollars in revenue
(11/12/2008) A new report from Oceana shows that action taken now to curb ocean acidification would not only preserve the world's coral reefs, but also save billions in lost revenue in the fishing and tourism industries.
Factoring social and economic instability into ecological catastrophe and the decline of western civilization
(11/12/2008) When proposing and exploring solutions to environmental crises we rarely, if ever, consider social and geopolitical factors such as massive refugee migrations, economic market instability and collapse, wars for resources, the peaking of oil, civil uprisings/riots, and the rise of fascism/military oppression. If we hope to create lasting and effective solutions to environmental issues of the 21st Century it is clear we must consider facets beyond the realm of traditional environmental science and shift towards multi-disciplinary systems-level approaches. In addition to the long list of existing and impending environmental crises (passing points-of-no-return in tropical deforestation and climate change, widespread coral bleaching, and the accelerating mass extinction of biodiversity) we must recognize and adapt to the effects of current and emerging social issues (resource wars, economic collapse, and the rise of fascism).
Effects of ocean acidification will come 30 years earlier than expected
(11/11/2008) The Southern Ocean may be 30 years closer to a tipping point for ocean acidification than previously believed, putting sea life at risk, according to research published in this week's Proceedings of the National Academy of Science.
In final weeks, President Bush aims to extend his environmental legacy
(11/09/2008) On Tuesday, November 4th, the people of the United States elected a new president, Senator Barack Obama. Many feel a new day is coming on a number of issues, including the environment. However the Bush Administration has 72 days left in its term and appears hopeful to use every one of those to make last-minute changes to environmental rules that will have wide-ranging impacts on the nation's endangered species, air, water, parks, and undeveloped land. As the administration has done since taking office eight years ago, it is working toward such policies—all of them controversial—to benefit industry at the cost of the environment and health safeguards.
