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.
Blackout in Brazil: Hydropower and Our Climate Conundrum
(11/19/2009) It’s everyone’s worst nightmare: being caught in an underground subway in the midst of a power outage. Yet, that is exactly what happened recently when Brazilian commuters in the city of São Paulo were trapped inside trains and literally had to be pulled out of subway cars. In addition to sparking problems in public transport, the blackout or apagão led to hospital emergencies and the shutting down of several airports. In all the power outage darkened approximately half of the South American nation, affecting sixty million people.
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."
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.
New report: boreal forests contain more carbon than tropical forest per hectare
(11/12/2009) A new report states that boreal forests store nearly twice as much carbon as tropical forests per hectare: a fact which researchers say should make the conservation of boreal forests as important as tropical in climate change negotiations. The report from the Canadian Boreal Initiative and the Boreal Songbird Initiative, entitled "The Carbon the World Forgot", estimates that the boreal forest—which survives in massive swathes across Alaska, Canada, Northern Europe, and Russia—stores 22 percent of all carbon on the earth's land surface. According to the study the boreal contains 703 gigatons of carbon, while the world's tropical forests contain 375 gigatons.
Declaration calls for more wilderness protected areas to combat global warming
(11/11/2009) Meeting this week in Merida, Mexico, the 9th World Wilderness Congress (WILD9) has released a declaration that calls for increasing wilderness protections in an effort to mitigate climate change. The declaration, which is signed by a number of influential organizations, argues that wilderness areas—both terrestrial and marine—act as carbon sinks, while preserving biodiversity and vital ecosystem services.
UN singles out US as the most important nation for global warming negotiations
(11/11/2009) Visiting Washington DC, Secretary-General Ban Ki-Moon stated that the United States was the world's most important actor when it comes to negotiations for a new climate change treaty, while urging the Senate to move forward on legislation.
Nations vulnerable to global warming present demands: carbon levels below 350ppm and billions in aid
(11/10/2009) A group of nations especially vulnerable to the effects of climate change have released a declaration calling for developed countries to keep CO2 emission below 350 parts per million (ppm) and to give 1.5 percent of their gross domestic product to aid developing nations in adapting to the myriad impacts of climate change.
Global warming threatens desert life
(11/09/2009) There have been numerous studies showing how climate change is impacting a variety of environments—from the Arctic to coral reefs to alpine—but how could a warmer world damage deserts, already the world's warmest and driest environments?
Fossil fuel subsidies "bringing us closer to irreversible climate change"
(11/06/2009) The Green Economy Coalition is urging G20 finance ministers to rapidly put an end to fossil fuel subsidies. In a letter to the ministers the coalition argues that these subsidies are contributing directly to climate change and making it difficult for the world to transition to a greener economy.
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.
Impasse over palm oil emissions at RSPO meeting
(11/04/2009) Environmentalists and palm oil producers meeting at the annual Roundtable on Sustainable Palm Oil (RSPO) were locked in an impasse over how to account for emissions from converting forests and peatlands to oil palm plantations, report conference attendees.
Gucci drops APP in pledge to save rainforests
(11/03/2009) One of the world's largest and most prestigious fashion brands has stated it will stop sourcing paper from Indonesian forests and will drop Asia Pulp and Paper (APP) as a supplier, which has become notorious for tropical deforestation. The move comes after pressure from the Rainforest Action Network (RAN) on the fashion industry to stop sourcing paper from threatened rainforests for their shopping bags.
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.
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.
Hummer owners view themselves as morally upright
(09/22/2009) For many the Hummer has become a symbol of all that is wrong with America: wastefulness without regard to consequences, entitlement beyond the scope of reason, and individualism to the point of arrogance.
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.
Fake Obama makes climate change top priority
(09/21/2009) In an effort to push the real President Obama to attend the UN Summit on Climate Change in December, a fake Obama took over on Friday.
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.
Russia's plan to mine peatlands for energy could release 113 gigatons of carbon
(09/08/2009) Wetlands International, a not-for-profit organization dedicated to preserving the world's wetlands, has warned of drastic environmental consequences if the Russia government goes ahead with plans to begin large scale peat mining, including the potential release of 113 gigatons of carbon.
Activists target Brazil's largest driver of deforestation: cattle ranching
(09/08/2009) Perhaps unexpectedly for a group with roots in confrontational activism, Amigos da Terra - Amazônia Brasileira is calling for a rather pragmatic approach to address to cattle ranching, the largest driver of deforestation in the Brazilian Amazon. The solution, says Roberto Smeraldi, founder and director of Amigos da Terra, involves improving the productivity of cattle ranching, thereby allowing forest to recover without sacrificing jobs or income; establishing a moratorium on new clearing; and recognizing the economic values of maintaining the ecological functions of Earth's largest rainforest.
Japan throws down gauntlet, vows to cut greenhouse gas emissions 25 percent by 2020
(09/07/2009) The new prime minister of Japan, Yukio Hatoyama, has thrown down the gauntlet to other industrialized nations in the lead-up to the UN Climate Change Summit in Copenhagen this December. He had pledged to cut his nation's greenhouse gas emissions 25 percent from 1990 levels (the set date for the Kyoto Treaty) by 2020.
Sea levels set to rise as Arctic warming replaces millennia long natural cooling cycle
(09/03/2009) According to a new study published in Science the Arctic should be cooling, and in fact has been cooling for millennia. But beginning in 1900 Arctic summer temperatures began rising until the mid-1990s when the cooling trend was completely overcome. Researchers fear that this sudden up-tick in temperatures could lead to rising sea levels threatening coastal cities and islands. "Scientists have known for a while that the current period of warming was preceded by a long-term cooling trend," said lead author Darrell Kaufman of Northern Arizona University. "But our reconstruction quantifies the cooling with greater certainty than ever before."
Investing in conservation could save global economy trillions of dollars annually
(09/03/2009) By investing billions in conserving natural areas now, governments could save trillions every year in ecosystem services, such as natural carbon sinks to fight climate change, according to a European report The Economics of Ecosystems and Biodiversity (TEEB).
Political heat rising on climate change, but does the United States feel it?
(09/02/2009) The UN Summit on Climate Change isn’t for three months, yet the political temperature has been rising steadily over the summer. The heat is especially focused on the three big players at the summit: China, India, and the United States.
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.
Greenhouse gas emissions drop in the EU for the fourth year in a row
(08/31/2009) In 2008 greenhouse gas emissions in the EU fell 1.3 percent, the European Environment Agency (EEA) said today. This figure measures only the emissions in the 15 EU countries that have commitments to reduce emissions, however when all 27 members of the EU are included, greenhouse gas emissions actually fell further: 1.5 percent.
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.
Environmental disappointments under Obama
(08/24/2009) While the President has been bogged down for the last couple months in an increasingly histrionic health-care debate-which has devolved so far into ridiculousness that one doesn't know whether to laugh or cry-environmental decisions, mostly from the President's appointees have still been coming fast and furious. However, while the administration started out pouring sunshine on the environment (after years of obfuscated drudgery under the Bush administration), they soon began to move away from truly progressive decisions on the environment and into the recognizable territory of playing it safe-and sometimes even stupid.
China moves forward on global warming: top scientists recommend emissions peak in 2030
(08/17/2009) In a move that many have seen as a step forward for China in terms of its willingness to combat climate change, the nation’s top climatologists have released a report recommending that China begin drawing down greenhouse gas emissions after 2030. The report comes just four months before a widely anticipated global meeting to set up a new international framework to combat climate change in Copenhagen, Denmark.
Boreal forests in wealthy countries being rapidly destroyed
(08/12/2009) Boreal forests in some of the world's wealthiest countries are being rapidly destroyed by human activities — including mining, logging, and purposely-set fires — report researchers writing in Trends in Ecology and Evolution.
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.
Are we on the brink of saving rainforests?
(07/22/2009) Until now saving rainforests seemed like an impossible mission. But the world is now warming to the idea that a proposed solution to help address climate change could offer a new way to unlock the value of forest without cutting it down.Deep in the Brazilian Amazon, members of the Surui tribe are developing a scheme that will reward them for protecting their rainforest home from encroachment by ranchers and illegal loggers. The project, initiated by the Surui themselves, will bring jobs as park guards and deliver health clinics, computers, and schools that will help youths retain traditional knowledge and cultural ties to the forest. Surprisingly, the states of California, Wisconsin and Illinois may finance the endeavor as part of their climate change mitigation programs.
Smart biofuels that don't hurt people or the environment are possible
(07/16/2009) Sustainable biofuels can be a reality but only in combination with reductions in fuel demand and increased productivity on existing agricultural lands, argue researchers writing in the journal Science. Five years ago biofuels were seen as a panacea for the world's energy hunger and the need to address climate change, but increased production of biofuels soon contributed to a clutch of problems, including competition with food, resulting in rising prices, and large-scale conversion of rainforests and tropical grasslands for feedstocks, resulting in biodiversity loss and increased greenhouse gas emissions. Environmentalists and scientists condemned many biofuels — including ethanol produced from Midwestern corn ethanol and biodiesel generated from European rapeseed and Southeast Asian palm oil — as a short-sighted energy solution. Some biofuels were found to be even worse for the environment, and more costly, than conventional gasoline. However some researchers remain optimistic that smart biofuel production could help meet energy demand without hurting people or the planet. In a Science Policy Forum piece, David Tilman and colleagues explore some of these options, noting that biofuels can be produced in substantial quantities at low environmental cost
A Tasmanian tragedy? : How the forestry industry has torn an island apart
(07/02/2009) This is by no means a new battle: in fact, Tasmanian industrial foresters and environmentalists have been fighting over the issue of clearcutting the island’s forests for decades. The battle—some would probably prefer 'war'—is over nothing less than the future of Tasmania. Some Tasmanians see the rich forests that surround them in terms of income, dollars and cents; they see money literally growing on trees, or more appropriately growing on monoculture plantations and government owned native forests. They see the wilderness of Tasmania as an exploitative resource.
Implications of the American Clean Energy and Security Act for conservation
(06/26/2009) Following today's passage of the American Clean Energy and Security Act (ACES) by the House of Representatives, The Natury Conservancy released a set of questions and answers with Mark Tercek, its chairman and CEO.
Global warming bill passes the House
(06/26/2009) The U.S. House of Representatives passed the country's first climate change legislation 219-212 on Friday. The vote was highly partisan with Democrats generally supporting the American Clean Energy and Security Act, and Republicans mostly opposing it.
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.
Scientists call on Obama for ‘maximum personal leadership’ to combat global warming
(06/22/2009) Twenty leading scientists have called on President Obama “to exercise maximum personal leadership” in tackling the threat posed by climate change.
New Yangtze River dam could doom more endangered species
(06/22/2009) Eight Chinese environmentalists and scientists have composed a letter warning that a new dam under consideration for the Yangtze River could lead to the extinction of several endangered species. The letter contends that Xiaonanhia Dam, which would be 30 kilometers upstream from the city of Chongqing, will negatively impact the river’s only fish reserve. Spanning 400 kilometers in the upper Yangtze, the reserve is home to 180 fish species, including the Endangered Chinese sturgeon, and the Critically Endangered Chinese paddlefish, as well as the finless porpoise.
What is the crop productivity and environmental impact of too much or too little fertilizer?
(06/18/2009) While the use of synthetic fertilizer has greatly increased agricultural production globally—helping to feed a global population that is not slowing down—it has brought with it high environmental costs. Fertilizer runoff has polluted many coastal regions creating ‘dead zones’ where the ocean is starved of oxygen by the influx of nitrogen. Synthetic fertilizers have also polluted the air with ammonia, and sent emissions of nitrous oxide into the atmosphere, contributing to global warming.
Lomborg calls for a carbon tax
(06/17/2009) Bjorn Lomborg, a Danish business school professor and author who has riled environmentalists by arguing that addressing climate change should be a lesser priority than health and nutrition initiatives, is calling for a $7 per ton tax on carbon dioxide emissions, reports the Wall Street Journal.
Burning fossil fuels is disrupting nitrogen cycle
(06/04/2009) The burning of fossil fuels has disrupted the nitrogen cycle by altering that amount of nitrogen in the biosphere, according to scientists from Brown University and the University of Washington. It has long been known that fossil fuel combustion releases nitric oxides into the air—which combine with other elements to form both smog and acid rain—but until now scientists have been unsure as to the extent nitric oxide emissions have affected the natural nitrogen cycle.
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.
Brazil's plan to save the Amazon rainforest
(06/02/2009) Accounting for roughly half of tropical deforestation between 2000 and 2005, Brazil is the most important supply-side player when it comes to developing a climate framework that includes reducing emissions from deforestation and forest degradation (REDD). But Brazil's position on REDD contrasts with proposals put forth by other tropical forest countries, including the Coalition for Rainforest Nations, a negotiating block of 15 countries. Instead of advocating a market-based approach to REDD, where credits generated from forest conservation would be traded between countries, Brazil is calling for a giant fund financed with donations from industrialized nations. Contributors would not be eligible for carbon credits that could be used to meet emission reduction obligations under a binding climate treaty.
US responsible for 29 percent of greenhouse gas emissions over past 150 years
(05/31/2009) In the past 150 years, the United States has emitted more greenhouse gas emissions than any other nation in the world, according to a recent report by Greenpeace. In fact, US emissions account for 29 percent of the world’s total since the mid-1800s. The US emitted 328,264 million metric tons of carbon dioxide (MtCO2) in the past 150 years, which is over 3 times the amount emitted by China in the same century-and-a-half.
