US emissions from coal could be stopped in 20 years
(05/03/2010) A new study in Environmental Science and Technology (ES&T) concludes that the US could stop all emissions from coal-fired plants within 20 years time using only existing technologies and some that will be ready within the next decade. Such an accomplishment would go a long way toward lowering the US's carbon emissions and mitigating the impact of climate change, according to the researchers.
Close to a billion species: ocean exploration reveals shocking diversity of tiny marine life
(04/19/2010) Biologists worldwide may have to start re-evaluating their estimates of the number of species on Earth, since expeditions documenting the oceans' tiniest species have revealed shocking diversity: in the tens of millions of species, at least, and according to one researcher "closer to a billion". Fourteen field projects sent out by the Census of Marine Life focused on the oceans' smallest inhabitants: microbes, zooplankton, and tiny burrowing species inhabiting the deep sea bed. What they found was astounding.
Chaos and the Accord: Climate Change, Tropical Forests and REDD+ after Copenhagen
(04/06/2010) The Copenhagen Accord, forged at COP15 upended international efforts to confront
climate change. Never before have 115 Heads of State gathered together at one
time, let alone for the singular purpose of crafting a new climate change
agreement. Even though the new Accord is still in intensive care, two things
are already clear. First, we have entered an entirely new world. And second,
tropical forests have the greatest potential to breathe life into the new
agreement.
Analysis shows Borneo can say 'no' to coal power
(03/17/2010) Plans for a coal power plant in the Malaysian state of Sabah in northern Borneo have run into stiff opposition. Environmentalists say the coal plant could damage extensive coral reef systems, pollute water supplies, open rainforests to mining, and contribute to global climate change, undercutting Sabah's image as a 'green' destination. The federal government contends that the coal plant is necessary to fix Sabah's energy problems. However, a recent energy audit by the Renewable and Appropriate Energy Laboratory (RAEL) at the University of California Berkeley shows that pollution-intensive coal doesn't have to be in Sabah's future.
Massive methane leak in Arctic could trigger abrupt warming
(03/04/2010) Methane, a greenhouse gas 30 times more potent than carbon, is spewing from what was believed to be an impermeable barrier in Siberia in amounts equal to methane releases from the world's oceans. The discovery has lead researchers to fear the possibility of abrupt climate warming. According to the study published in Science, subsea permafrost below the East Siberian Arctic Shelf has become compromised, leaking vast amounts of methane into the atmosphere.
Amazon rainforest will bear cost of biofuel policies in Brazil
(02/08/2010) Business-as-usual agricultural expansion to meet biofuel production targets for 2020 will take a heavy toll on Brazil's Amazon rainforest in coming years, undermining the potential emissions savings of transitioning from fossil fuels to biofuels, warns a new paper published in the Proceedings of the National Academy of Sciences (PNAS). The research suggests that intensification of cattle ranching, combined with efforts to promote high-yielding oil crops like oil palm could lessen forecast greenhouse gas emissions from indirect land use in the region.
Obama pledges to reduce government emissions 28% by 2020
(01/31/2010) The U.S. government aims to cut its greenhouse gas emissions 28 percent by 2020 under an order announced Friday by President Obama.
New report: world must change model of economic growth to avert environmental disaster
(01/25/2010) For decades industrialized nations have measured their success by the size of their annual GDP (Gross Domestic Product), i.e. economic growth. The current economic model calls for unending growth—as well as ever-rising consumerism—just to remain stable. However, a new report by the New Economics Foundation (nef) states that if countries continue down a path of unending growth, the world will be unable to tackle climate change and other environmental issues.
Indonesian government report recommends moratorium on peatlands conversion
(01/19/2010) A study issued by Indonesian government recommends a moratorium on peatlands conversion in order to meet its greenhouse gas emissions target pledged for 2020, reports the Jakarta Post. The report, commissioned by the National Development Planning Agency (Bappenas), says that conversion of peatlands accounts for 50 percent of Indonesia's greenhouse gas emissions but only one percent of GDP. A ban on conversion would therefore be a cost-effective way for the country to achieve its goal of reducing carbon emissions 26 percent from a projected baseline by 2020. But the recommendation is likely to face strong resistance from plantation developers eager to expand operations in peatland areas. Last year the Agricultural Ministry lifted a moratorium on the conversion of peatlands of less than 3 meters in depth for oil palm plantations. Environmentalists said the move would release billions of tons of carbon dioxide.
Forest carbon conservation projects top $100 million
(01/14/2010) The market for carbon credits generated through forest conservation topped $100 million from 2007 through the first half of 2009, despite a global recession and plunging carbon prices in regulated markets, reports a new assessment by Ecosystem Marketplace.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Scientists call for an end to mountaintop removal mining in the US
(01/07/2010) A group of scientists have called for the Obama Administration to place a moratorium on infamous mountain top mining due to "growing scientific evidence" of severe environmental degradation and serious impacts on human health, including cancer. The article, published in Science, is written by a dozen influential scientists, including hydrologists, ecologists, and engineers.
Underwater rocks could be used for massive carbon storage on America's East Coast
(01/05/2010) Considering it is unlikely that global carbon emissions will start dropping anytime soon, researchers are beginning to look at other methods to combat climate change. One of these is to hook polluting power plants up to massive carbon sinks where instead of the carbon going into the atmosphere it would be stored away in rocks. The process is known as carbon capture and storage or CCS. But before one can even debate the pros and cons of setting up CCS, scientists must see if high-quality sites exist.
Brazil to keep emissions reductions pledge despite failed climate summit
(12/30/2009)
Brazil will honor its pledge to reduce greenhouse gas emissions 14-19 percent from 2005 levels despite the failure of this month's climate meeting in Copenhagen to establish binding limits on emissions, reports Reuters.
Coal plant could damage rainforest reserves, coral reefs, palm oil plantations in Malaysian Borneo
(12/20/2009) A proposed coal-fired power plant in Malaysian Borneo could damage the region's world-renowned coral reefs, pollute air and water supplies, open Sabah's biodiverse rainforests to mining, and undermine the state's effort to promote itself as a destination for "green" investment and ecotourism, warn environmentalists leading an effort to block the project. The scheme, which is backed by the federal Tenaga Nasional Berhad and state energy company, Sabah Electricity Sdn. Bhd, has faced strong opposition and already been forced to re-locate twice since it was conceived more than two years ago. The 300-MW plant is now planned for a coastal area that is situated in the middle of the Coral Triangle/Sulu Sulawesi Marine Ecoregion, an area renowned for astounding levels of biodiversity.
Climate change causing irreversible acidification in world's oceans
(12/15/2009) A new study from the Secretariat of the Convention on Biological Diversity has synthesized over 300 reports on ocean acidification caused by climate change. The report finds that increasing acidification will lead to irreversible damage in the world's oceans, creating a less biodiverse marine environment. Released today the report determines that the threat to marine life by ocean acidification must be considered by policymakers at the UN Climate Change Conference in Copenhagen.
Amazon cattle ranching accounts for half of Brazil's CO2 emissions
(12/12/2009) Cattle ranching accounts for half of Brazil's greenhouse gas emissions according to a new study led by scientists from Brazil's National Space Institute for Space Research (INPE).
Europe says US and China emission targets don't go far enough
(12/07/2009) At a press conference during the first day of the UN Copenhagen Climate Change Conference, the European Union has stated it will not raise its emissions cuts from 20 percent to 30 percent by 2020 (over 1990 levels) unless the US and China go further in their cuts.
Profile of the carbon footprint of the global poor: the challenge of alleviating poverty and fighting global warming
(12/07/2009) Two of the world's most serious issues—poverty and climate change—are interconnected. With a rise in one's income there usually comes a rise in one's carbon footprint, thereby threatening the environment. Wealthy nations have the highest per capita carbon footprints, while developing nations like India and China—which are experiencing unprecedented economic growth—are becoming massive contributors of greenhouse gases. However, it is those who have the smallest carbon footprint—the world's poor—who currently suffer most from climate change. Food crises, water shortages, extreme weather, and rising sea levels have all hit the poor the hardest.
Email scandal may be turning against climate change deniers
(12/07/2009) It may be that climate change scientists and policymakers have simply had enough, and it may be that the emails which were hacked did not reveal the massive conspiracy that they were supposed to, either way climatologists and politicians have gone on the offensive against claims that the hacked emails from the East Anglia's Climate Research Unit are evidence that climate change is a conspiracy or hoax.
Obama administration about to declare carbon dioxide a danger to the public, allowing regulation
(12/06/2009) The day before talks start in Copenhagen on a new international treaty to combat climate change, the Wall Street Journal reports that the Environmental Protection Agency (EPA) in the United States is set to declare carbon dioxide a 'public danger' as soon as Monday.
Highest rate of CO2 emissions growth since 1990
(12/04/2009) Between 1990 and 2005 Vietnam had the highest rate of emissions growth among countries that emitted more than 100 million tons of CO2 in any year during the past three decades, according to mongabay.com's analysis of emissions data from the Oak Ridge National Laboratory's Carbon Dioxide Information Analysis Center (CDIAC).
World leaders falling over themselves to show up at Copenhagen
(12/01/2009) If you’re a world leader and you won’t be in Copenhagen next week you might feel out of the loop. Currently 98 heads of state have agreed to attend the Climate Change Summit in Copenhagen—nearly half of the 192 member nations of the UN.
Americans throw away enough food every year to feed 200 million adults
(11/30/2009) The amount of food Americans throw away has risen by approximately 50 percent since 1974 according to a new study in PLoS ONE. American now waste on average 1400 calories per person everyday, equaling 150 trillion calories a year nationwide. Considering that the average person requires approximately 2,000 calories a day, this means that the US could feed over 200 million adults every year with the food that ends up in the trash. Currently, the UN estimates that one billion people—an historical record—are going hungry worldwide.
Zoos call for deeper emission cuts to save life on Earth
(11/30/2009) To save species around the world zoos say deeper emission cuts are needed than governments are currently proposing. Over 200 zoos worldwide have signed a petition calling on governments to set the target of atmospheric carbon below 350 parts per million (ppm) far lower than most government targets.
Reforestation effort would lower Britain's greenhouse gas emissions by 10 percent
(11/25/2009) A study by Britain's Forestry Commission found that planting 23,000 hectares of forest every year for the next 40 years would lower the island nation's greenhouse gas emissions by 10 percent, according to reporting by the BBC.
Land of plenty: 50 percent rise in the amount of food wasted in America worsens global warming, consumes freshwater
(11/25/2009) Just before Thanksgiving a new study shows that Americans are throwing away more food than ever. Since 1974 the amount of food Americans water per capita has risen by approximately 50 percent, according to a new study in PLoS ONE. Researchers found that food waste is adding to America's greenhouse gas emissions and accounts for over one quarter of the nation's freshwater consumption every year.
The US will set emissions target, but is this a turning point for success at Copenhagen?
(11/24/2009) Today may mark a turning point for a successful negotiation at the Climate Change Summit in Copenhagen or it may just be another blip in the up-and-down news cycles that have preceded the summit for months.
Deforestation emissions should be shared between producer and consumer, argues study
(11/19/2009) Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.
Oceans' ability to sequester carbon diminishing
(11/18/2009) A new study—the first of its kind—has completed an annual accounting of the oceans' intake of carbon over the past 250 years, and the news is troubling. According to the study, published in Nature, the oceans' ability to sequester carbon is struggling to keep-up with mankind's ever-growing emissions. Since 2000 researchers estimate that while every year the oceans continue to sequester more anthropogenic carbon emission, the overall proportion of carbon taken in by the oceans is declining.
Record year for CO2 emissions, even with economic slowdown
(11/17/2009) 8.7 billion tons of carbon dioxide was emitted into the earth's atmosphere in 2008, a growth of 2 percent despite the economic crisis. This averages out to each person contributing a record high of 1.3 tons of carbon, according to a report in the journal Nature Science. While the global recession slowed the growth of fossil fuel emissions for the first time this decade, it did not lower emissions altogether.
Coastal habitats may sequester 50 times more carbon than tropical forests by area
(11/16/2009) Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marhses—sequester as much as 50 times the amount of carbon in their soil per hectare as tropical forest. "The key difference between these coastal habitats and forests is that mangroves, seagrasses and the plants in salt marshes are extremely efficient at burying carbon in the sediment below them where it can stay for centuries or even millennia."
Asia-Pacific leaders drop emissions cuts from Copenhagen agenda
(11/16/2009) Leaders of the 21-member Asia Pacific Economic Cooperation (APEC) dropped the reference to greenhouse gas emissions cuts from their declaration released Sunday, reports Reuters.
Brazil pledges to restrain emissions growth
(11/15/2009) In a move that some observers say could provide a path forward on a future climate agreement that includes emissions cuts in developing countries, Brazilian President Luiz Inacio Lula da Silva said his country will aim to reduce emissions 14 to 19 percent below 2005 levels by 2020.
EU is 2nd largest source of peat emissions after Indonesia, finds global peat survey
(11/04/2009) The EU is the world's second largest source of carbon dioxide emissions from peatlands drainage, after Indonesia, reports the first country-by-country assessment of peat stocks. The study, conducted by Wetlands International and Greifswald University, found that drainage of wetlands for agriculture, forestry and peat extraction causes 1.3 billion tons of carbon dioxide emissions per year. Emissions from fires and peat mining (for horticulture and fuel) amount to another 700,000 million tons per year.
Emissions from deforestation overestimated; 12% rather than 17%
(11/04/2009) Greenhouse gas emissions from deforestation are lower than previously believed, according to a new study published in Nature Geoscience. The findings mean that developing countries may see less money under Reducing Emissions from Deforestation and Degradation, a proposed climate change mitigation mechanism.
Carbon accounting must not neglect emissions from bioenergy production and use
(10/29/2009) Carbon accounting used in the Kyoto Protocol and other climate legislation currently neglects CO2 emissions from the production of biofuels, a loophole that could drive large-scale destruction of tropical forests and exacerbate global warming, warned researchers writing last week in the journal Science.
Brazil to support REDD in Copenhagen
(10/28/2009) Brazil will conditionally support a proposed climate change mitigation scheme that will compensate tropical countries for preserving their forests, reports Reuters.
Freshwater species worse off than land or marine
(10/15/2009) Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
500 global business leaders call for 50-85% cut in emissions by 2050
(09/22/2009) In a statement issued today, more than 500 business leaders have called for "an ambitious, robust and equitable global deal" on climate change.
Indonesia: emissions to rise 50% by 2030, 3rd largest GHG emitter
(09/22/2009) A report released by the Indonesian government shows the country is the world's third largest greenhouse gas emitter, largely as a result of the destruction of rainforests and carbon-dense peatlands. Indonesia accounts for 8 percent of global carbon dioxide emissions.
US subsidies of oil and coal more than double the subsidies of renewable energy
(09/21/2009) During the fiscal years of 2002-2008 the United States handed out subsidies to fossil fuel industries to a tune of 72 billion dollars, while renewable energy subsidies, during the same period, reached 29 billion dollars.
Climate Crisis Sparks Radical Response
(09/17/2009) The global political process to counter runaway climate change has become, for practical purposes, irrelevant. None of the currently proposed emissions reductions being seriously considered in policy making are appropriate to meet the severity of the situation. This overwhelming failure on the part of world governments is pushing the rapid unification of environmentalists, activists, scientists, and others to push for direct, immediate change.
France announces carbon tax
(09/10/2009) The President of France, Nicolas Sarkozy, has announced that he will implement a carbon tax to help "save the human race" from global warming.
Maldives president tells world: 'please, don’t be stupid' on climate change
(09/01/2009) "Please, don't be stupid," Mohamed Nasheed told the world regarding the need to act decisively against climate change. To underlie his message, Nasheed announced that his country will become carbon neutral in ten years.
Destructive farming practices of early civilization may have altered climate long before industrial era
(08/31/2009) William Ruddiman has become well known for his theory that human-induced climate change started long before the Industrial Age. In 2003 he first brought forth the theory that the Neolithic Revolution-when some humans turned from hunter-gathering to large-scale farming-caused a shift in the global climate 7,000 years ago.
India surpasses Japan in CO2 emissions
(08/12/2009) India accounts for about five percent of global carbon dioxide emissions, roughly a quarter of the emissions of China and the United States, according to an Indian government study reported by Reuters.
Emissions from Amazon deforestation to rise as loggers move deeper into the rainforest
(07/31/2009) Emissions from Amazon deforestation are growing as developers move deeper into old-growth forest areas where carbon density is higher, report scientists writing in Geophysical Research Letters.
Temperate forests store more carbon than tropical forests, finds study
(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.
