Protecting original wetlands far preferable to restoration

(01/26/2012) Even after 100 years have passed a restored wetland may not reach the state of its former glory. A new study in the open access journal PLoS Biology finds that restored wetlands may take centuries to recover the biodiversity and carbon sequestration of original wetlands, if they ever do. The study questions laws, such as in the U.S., which allow the destruction of an original wetland so long as a similar wetland is restored elsewhere.


One company behind U.S.'s top three biggest greenhouse gas emitters

(01/16/2012) The Atlanta-based Southern company owns the top three biggest sources of greenhouse gas emissions in the U.S. according to recent data released by the Environmental Protection Agency (EPA). Three of Southern's coal-fired plants—two in Georgia and one in Alabama—account for around 64.74 million metric tons of total greenhouse gas emissions, higher than all of Finland's carbon emission in 2008.


Targeting methane, black carbon could buy world a little time on climate change

(01/12/2012) A new study in Science argues that reducing methane and black carbon emissions would bring global health, agriculture, and climate benefits. While such reductions would not replace the need to reduce CO2 emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added benefits of saving lives and boosting agricultural yields. In addition, the authors contend that dealing with black carbon and methane now would be inexpensive and politically feasible.


Ecuador makes $116 million to not drill for oil in Amazon

(01/02/2012) A possibly ground-breaking idea has been kept on life support after Ecuador revealed its Yasuni-ITT Initiative had raked in $116 million before the end of the year, breaking the $100 million mark that Ecuador said it needed to keep the program alive. Ecuador is proposing to not drill for an estimated 850 million barrels of oil in the Ishpingo-Tambococha-Tiputinin (ITT) blocs of Yasuni National Park if the international community pledges $3.6 billion to a United Nations Development Fund (UNDF), or about half of what the oil is currently worth. The Yasuni-ITT Initiative would preserve arguably the most biodiverse region on Earth from oil exploitation, safeguard indigenous populations, and keep an estimated 410 million tons of CO2 out of the atmosphere. However, the initiative is not without its detractors, some arguing the program is little more than blackmail; meanwhile proponents say it could prove an effective way to combat climate change, deforestation, and mass extinction.


Mixed reactions to the Durban agreement

(12/12/2011) Early Sunday morning over 190 of the world's countries signed on to a new climate agreement at the 17th UN Framework Convention on Climate Change (UNFCCC) in Durban, South Africa. The summit was supposed to end on Friday, but marathon negotiations pushed government officials to burn the midnight oil for about 36 extra hours. The final agreement was better than many expected out of the two week summit, but still very far from what science says is necessary to ensure the world does not suffer catastrophic climate change.


Current emission pledges will raise temperature 3.5 degrees Celsius

(12/06/2011) New research announced at the 17th UN Climate Summit in Durban, South Africa finds that under current pledges for reducing emissions the global temperature will rise by 3.5 degrees Celsius (6.3 degrees Fahrenheit) from historic levels, reports the AFP. This is nearly double world nations' pledge to keep warming below 2 degrees Celsius (3.6 degrees Fahrenheit). The report flies in the face of recent arguments by the U.S. and others at Durban that current pledges are adequate through 2020.


Carbon credit market for HFC-23 racked by fraud

(11/30/2011) An effort to decrease emissions of the super greenhouse gas HFC-23 has led to a largely-false carbon market that should be eliminated, argues the Environmental Investigation Agency (EIA). HFC-23 is a byproduct of the refrigerant HCFC-22, which is currently being phased out under the Montreal Protocol for its ozone-depleting and greenhouse gas properties. However, the effort to reduce HFC-23 through a carbon market has been hampered by companies in India and China producing extra HFC-23 just so they can capture and destroy it—and receive lucrative carbon funds.


Featured video: are hydroelectric dams a solution to climate change?

(11/28/2011) A new video from NGOs International Rivers and Friends of the Earth International argues that a spree of dam building in the tropics is a false solution to the climate crisis. The video has been released to coincide with the UN's 17th Climate Summit now beginning in Durban, South Africa.


Deforestation could be stopped by 2020

(11/28/2011) If governments commit to an international program to save forests known as REDD+, deforestation could be nearly zero in less than a decade, argues the Living Forests Report from the World Wide Fund for Nature (WWF). REDD+, which stands for Reduced Emissions from Deforestation and Degradation, is a program that would pay developing nations to preserve forests for their ability to sequester carbon. Government officials begin meeting tomorrow in Durban, South Africa for the 17th UN climate summit, and REDD+ will be among many topics discussed.


Greenhouse gases hit new record in atmosphere as officials head to UN climate summit

(11/28/2011) The concentration of greenhouse gases in the atmosphere hit a new record in 2010, according to the UN's World Meteorological Organization (WMO), which found that warming from greenhouse gases rose 29 percent from 1990 to 2010. The announcement was made just a few days prior to officials meet at the 17th Climate Conference in Durban, South Africa, where expectations are low for a strong, binding agreement with a number of wealthy nations stating they expect no new agreement to take affect until 2020.


The dam-maker: China involved in 289 dam projects worldwide

(11/06/2011) China is currently involved in 289 hydroelectric projects worldwide, as reported by International Rivers. Most of the dams are built for hydropower, and over half are considered 'large' projects. The list includes completed dams, one currently under construction, and ones in initial planning stages.


Last year's greenhouse gas emissions topple worst-case scenario

(11/06/2011) Global greenhouse gas emissions last year exceeded worst-case scenario predictions from just four years before, according to the US Department of Energy (DOE). A rise of 6 percent (564 million additional tons) over 2009 levels was largely driven by three nations: the US, India, and China. Emissions from burning coal jumped 8 percent overall. The new data, supported by a similar report from International Energy Agency (IEA), make it even more difficult for nations to make good on a previous pledge to hold back the world from warming over 2 degrees Celsius.


Hydroelectric dam still a greenhouse gas source after 10 years

(11/01/2011) Hydroelectric power is often promoted as green energy, yet dams, especially in the tropics, can be significant sources of greenhouse gas emissions. When built, reservoirs trap vegetation, which, as it rots, emits both methane and carbon into the atmosphere. A new study in Science of the Total Environment found that a dam in Lao PDR remained a significant source of greenhouse gas emission even a decade after construction.


Sober up: world running out of time to keep planet from over-heating

(10/24/2011) If governments are to keep the pledge they made in Copenhagen to limit global warming within the 'safe range' of two degrees Celsius, they are running out of time, according to two sobering papers from Nature. One of the studies finds that if the world is to have a 66 percent chance of staying below a rise of two degrees Celsius, greenhouse gas emissions would need to peak in less than a decade and fall quickly thereafter. The other study predicts that pats of Europe, Asia, North Africa and Canada could see a rise beyond two degrees Celsius within just twenty years.


Australia's carbon tax moves closer to reality

(10/12/2011) By a margin of just two votes (74-72), Australia's plan to put a price on carbon passed its toughest hurdle today. It is now expected that the Australian legislator will moved forward to put the carbon tax into law. The carbon tax, pushed aggressively by Australian Prime Minister Julia Gillard, was just as ferociously opposed by business leaders and opposition party leader, Tony Abbott.


Climate test for Obama: 1,252 people arrested over notorious oil pipeline

(09/06/2011) Two weeks of climate disobedience at the White House ended over the weekend with 1,252 people arrested in total. Activists were protesting the controversial Keystone XL pipeline in an effort to pressure US President Barack Obama to turn down the project. If built the pipeline would bring oil from Alberta's tar sands through six US states down to Texas refineries. While protestors fear pollution from potential spills, especially in the Ogallala Aquifer which supplies water to millions, the major fight behind the pipeline is climate change: Canada's tar sands emit significantly more carbon than conventional sources of oil.


Australia launches limited carbon tax

(07/11/2011) Australia's 500 largest polluters will pay AU$23 ($24.60) per ton of carbon dioxide emitted beginning July 2012 under a plan announced by Australian prime minister Julia Gilliard.


Current carbon releases faster than at any time on record

(06/13/2011) The Paleocene-Eocene Thermal Maximum (PETM), a period of global warming that occurred nearly 56 million years ago due to massive releases of greenhouse gases, is frequently referenced as an analogue for projected climate change. However, recent findings suggest the current rate of carbon release is almost 10 times as rapid as at the peak of the PETM—and that biological systems may be significantly less able to adapt.


Arctic on the line: oil industry versus Greenpeace at the top of the world

(06/06/2011) At the top of the world sits a lone region of shifting sea ice, bare islands, and strange creatures. For most of human history the Arctic remained inaccessible to all but the hardiest of peoples, keeping it relatively pristine and untouched. But today, the Arctic is arguably changing faster than anywhere else on Earth due to global climate change. Greenhouse gases from society have heated up parts of the Arctic over the past half-century by 4-5 degrees Fahrenheit, leading to a staggering decline in the Arctic sea ice. The large-scale changes suffered by the Arctic have created a new debate over conservation and exploitation, a debate currently represented by the protests of Greenpeace against oil company Cairn Energy, both of whom have been interviewed by mongabay.com (see below).


World Bank proposes to limit funding to coal plants

(04/05/2011) Following years of criticism from environmentalists and some governments the World Bank has proposed new rules regarding carbon-intensive coal plants, reports the Guardian. The new rules would allow lending for coal-fired plants only to the world's poorest nations and would only lend after other alternatives, such as renewable energy, had been ruled out.


15 conservation issues to watch

(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.


Indigenous leaders take fight over Amazon dams to Europe

(03/02/2011) Three indigenous Amazonian leaders spent this week touring Europe to raise awareness about the threat that a number of proposed monster dams pose to their people and the Amazon forest. Culminating in a press conference and protests in London, the international trip hopes to build pressure to stop three current hydroelectric projects, one in Peru, including six dams, and two in Brazil, the Madeira basin industrial complex and the massive Belo Monte dam. The indigenous leaders made the trip with the NGO Rainforest Foundation UK, including support from Amazon Watch, International Rivers, and Rainforest Concern.


The ocean crisis: hope in troubled waters, an interview with Carl Safina

(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.


Is Obama's clean energy revolution possible?

(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world's largest economy. Describing the challenge as 'this generation's Sputnik moment' the US president set a goal of producing 80 percent of America's energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. "Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. "It is a question of whether we have the societal and political will."


Amount of carbon absorbed by ecosystems each year is grossly overstated, says new study

(01/17/2011) According to a new paper published in Science, current carbon accounting methods significantly overstate the amount of carbon that can be absorbed by forests, plains, and other terrestrial ecosystems. That is because most current carbon accounting methods do not consider the methane and carbon dioxide released naturally by rivers, streams, and lakes. This new paper suggests that rivers, streams, and lakes emit the equivalent of 2.05 billion metric tons of carbon every year. (By comparison, all the terrestrial ecosystems on the world’s continents are thought to absorb around 2.6 billion metric tons of carbon each year). This is, as the lead author of the paper said, is a “major accounting error”.


Formal petition filed against Belo Monte dam

(11/11/2010) The struggle against Brazil's Belo Monte dam on the Xingu River continues as today indigenous groups sent a formal petition to the Inter-American Commission on Human Rights (IACHR) to suspend the dam's construction, stating the dam violates human rights. The dam, which has been contentious in Brazil for decades, would flood 500 square miles of rainforest, lead to the removal of at least 12,000 people in the region, and upturn the lives of 45,000 indigenous people who depend on the Xingu River for survival.


US elects barrage of climate change deniers, threatening support for green energy

(11/03/2010) The US midterm election, which won Republicans the House but safeguarded the Senate for Democrats, has brought in a number of self-proclaimed climate change deniers, ending any likelihood that an energy bill will be passed over the next two years and essentially stumbling the White House's strategy on climate change. Newly elected Republican Senators Rand Paul of Kentucky and Marc Rubio of Florida, both members of the nascent Tea Party, have stated they do not believe in climate change despite that scientists overwhelming agree the Earth is warming due to human impacts.


Space tourism will worsen climate change

(10/24/2010) Have $200,000 to spend on a seat into space? You may want to re-think the expenditure given a new study in Geophysical Research Letters that shows space tourism will likely aggravate global climate change. Using sophisticated modeling, the researchers found that the biggest impact of a rise in space tourism on global temperatures won't be due to carbon emissions, but black carbon, often in the form of soot.


Majority of Americans confused on climate change basics

(10/17/2010) Most Americans don't understand the basics of climate change, according to a new poll by researchers with Yale. The poll found that over half of Americans deserve an 'F' on basic understanding of climate science and climate change, while only 1% would receive an 'A'.


Citizens of 188 countries challenge leaders on climate change

(10/11/2010) As world leaders continue to fumble a coherent, rapid, and comprehensive response to climate change, citizens from around the world yesterday sent a message to inert politicians by participating in over 7,300 events against climate change, according to 350.org, the head organizer of the day dubbed the 'Global Work Party'. "The fossil fuel industry may have thought that the collapse of the Copenhagen talks and its victory in the U.S. Congress were the final word—that people would give up in discouragement," said, Bill McKibben, founder of 350.org, so-called because 350 parts per millions (ppm) is the 'safe' amount of carbon in the atmosphere according to many scientists. Currently the concentration is around 390 ppm.


146 dams threaten Amazon basin

(08/19/2010) Although developers and government often tout dams as environmentally-friendly energy sources, this is not always the case. Dams impact river flows, changing ecosystems indefinitely; they may flood large areas forcing people and wildlife to move; and in the tropics they can also become massive source of greenhouse gases due to emissions of methane. Despite these concerns, the Amazon basin—the world's largest tropical rainforest—is being seen as prime development for hydropower projects. Currently five nations—Brazil, Bolivia, Colombia, Ecuador, and Peru—are planning over 146 big dams in the Amazon Basin. Some of these dams would flood pristine rainforests, others threaten indigenous people, and all would change the Amazonian ecosystem. Now a new website, Dams in Amazonia, outlines the sites and impacts of these dams with an interactive map.


Record highs, forest fires, and ash-fog engulf Moscow

(07/27/2010) Moscow and parts of Russia have been hit by record high temperatures and forest fires. Ashen fog from peat forests burning near Moscow has prompted officials to warn elderly and those with heart or bronchial problems to stay inside. Workers should be allowed a siesta to rest in the afternoon, as well, said the Russia's chief health official.


Large-scale forest destruction in Sumatra undermines Indonesia's deal with Norway

(07/13/2010) While the Indonesian government basks in a recent agreement with Norway to slow deforestation to the tune of a billion US dollars, a new report by Eyes on the Forest shows photographic evidence of largely government sanctioned deforestation that flouts several Indonesia laws. Potentially embarrassing, the report and photos reveal that two companies, Asian Pulp and Paper (APP) and Asia Pacific Resource International (APRIL), have destroyed 5 percent of Riau province's forests since 2009, including deep peatlands, high conservation value forests (HCVF), Critically Endangered Sumatran tiger habitat, and forest within the Giam Siak Kecil- Bukit Batu UNESCO Biosphere Reserve. In total, over 130,000 hectares (an area larger than Hong Kong) of mostly peat forest were destroyed for pulp.


Environmentalists and indigenous groups condemn plan for six dams in Peruvian Amazon

(06/21/2010) Environmentalists and indigenous groups have come together to condemn a 15 million US dollar plan for six hydroelectric dams in the Peruvian Amazon, signed last week by Brazilian President Luiz Inácio Lula da Silva and Peruvian President, Alan Garcia. While the six dams would produce over 6,000 megawatts, mostly for Brazil, critics say the dams will flood tens of thousands of hectares of rainforest, devastate the lifestyles of a number of indigenous groups, and only serve big Brazilian corporations.


Methane and Climate Change: From the Amazon to the Gulf of Mexico

(06/20/2010) In surveying the environmental damage unleashed from the BP oil spill, could we be missing the 800-pound gorilla in the closet? While oil poses undeniable ecological risks, methane (CH4) could prove daunting as well. As it turns out, crude which is destroying the Gulf of Mexico contains about 40 percent methane which may suffocate marine life and create vast “dead zones” where oxygen becomes so depleted that nothing is allowed to live.


The bluefin tuna wars: Greenpeace and Sea Shepherd step up tactics to save Critically Endangered species

(06/07/2010) Things have become ugly in the Mediterranean: over the weekend, fishermen and Greenpeace activists squared off over the fate of the Critically Endangered bluefin tuna. One run-in, in which Greenpeace worked to free tuna from fishermen's nets, left one activist in the hospital after a fisherman sunk a hook in the activist's leg. Meanwhile, the Sea Shepherd Conservation Society has announced a 'Blue Rage' campaign that will target illegal fishing of bluefin tuna.


A total ban on primary forest logging needed to save the world, an interview with activist Glen Barry

(06/02/2010) Radical, controversial, ahead-of-his-time, brilliant, or extremist: call Dr. Glen Barry, the head of Ecological Internet, what you will, but there is no question that his environmental advocacy group has achieved major successes in the past years, even if many of these are below the radar of big conservation groups and mainstream media. "We tend to be a little different than many organizations in that we do take a deep ecology, or biocentric approach," Barry says of the organization he heads. "[Ecological Internet] is very, very concerned about the state of the planet. It is my analysis that we have passed the carrying capacity of the Earth, that in several matters we have crossed different ecosystem tipping points or are near doing so. And we really act with more urgency, and more ecological science, than I think the average campaign organization."


18,225 new species discovered in 2008

(05/27/2010) In the 2010 State of Observed Species researchers have announced that 18,225 living species were discovered in 2008. In addition, 2,140 new extinct species were discovered byway of fossils.


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.


World failing on every environmental issue: an op-ed for Earth Day

(04/22/2010) The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the white rhino—from extinction; or preserving an ecological region like the Amazon. That was a different age. Today we speak of preserving world biodiversity, of saving the 'lungs of the planet', of mitigating global climate change. No longer are humans over-reaching in just one region, but we are overreaching the whole planet, stretching ecological systems to a breaking point. While we are aware of the issues that threaten the well-being of life on this planet, including our own, how are we progressing on solutions?


Got milk: 3 percent of greenhouse gases from milk production

(04/21/2010) Just less than 3 percent of the world's greenhouse gas emissions come from the production of milk, according to a new study by the UN Food and Agricultural Organization (FAO). Covering dairy producing animals from small nomadic herds to massive industrialized dairy operations, the FAO study factors in the production, processing, and transportation of milk as well as the fertilizer, pesticides, and feed used in the dairy industry. The total rises 4 percent if using dairy animals for meat is included.


Just how bad is meat-eating for the environment?

(03/28/2010) Meat is booming. In the past thirty years, livestock production has increased threefold. In many parts of the world where incomes are expanding, meat, once a delicacy, is now eaten regularly and voraciously. But what are the environmental impacts of this 'livestock revolution'? Two recent studies look at the global impact of the livestock industry, one alleges that its environmental impacts in relation to greenhouse gas emissions has been overestimated, while the other takes a holistic view of the industry's environmental impact.


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.


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.


Will it be possible to feed nine billion people sustainably?

(01/28/2010) Sometime around 2050 researchers estimate that the global population will level-out at nine billion people, adding over two billion more people to the planet. Since, one billion of the world's population (more than one in seven) are currently going hungry—the largest number in all of history—scientists are struggling with how, not only to feed those who are hungry today, but also the additional two billion that will soon grace our planet. In a new paper in Science researchers make recommendations on how the world may one day feed nine billion people—sustainably.


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.


Sixty corporations volunteer to measure full lifecycle emissions of products

(01/20/2010) Well-known corporations like Airbus, Levi Strauss & Co., 3M, DuPont, and Kraft Foods are volunteering to 'road test' a new global framework to measure the full lifecycle greenhouse gas emission of consumer products from blue jeans to manufactured steel.


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.


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.
