(01/14/2014) Carbon dioxide emissions rose two percent in the U.S. last year, according to preliminary data from the Energy Information Administration. Emissions rose largely due to increased coal consumption, the first such rise in U.S. emissions since 2010. Still, the annual emissions remain well below the peak hit in 2007 when emissions hit 6 billion tons.
Chickens before cows: new study finds cattle have outsized greenhouse gas footprint
(12/19/2013) If you want to lower your greenhouse gas emissions, choose chicken or poultry over beef and dairy, according to a massive new study in the Proceedings of the National Academy of Sciences (PNAS). The study finds that global cattle production—both for beef and dairy—is responsible for a whopping 77 percent of the world's greenhouse gases attributed to livestock. Meanwhile, pork and poultry account for only 10 percent the greenhouse gases from livestock.
Top scientists propose ambitious plans to safeguard world from devastating climate change
(12/05/2013) Two degrees is too much: that's the conclusion of a landmark new paper by top economists and climatologists, including James Hansen formerly of NASA. The paper, appearing in the open-access journal PLoS ONE, argues that global society must aim for only one degree Celsius of warming above pre-industrial levels to avoid the worst impact of climate change, and not the two degrees Celsius agreed on by the world's governments. But given that the world's governments are not yet on track to even achieve the two degree target, how could we lock in just one? A combination of renewable energy, nuclear power, and, most importantly, a rising price on carbon emissions, according to the eighteen scientists.
Humans are not apex predators, but meat-eating on the rise worldwide
(12/05/2013) A new paper in Proceedings of the National Academy of Sciences has measured the "trophic level" of human beings for the first time. Falling between 1 and 5.5, trophic levels refer to where species fit on the food chain. Apex predators like tigers and sharks are given a 5.5 on trophic scale since they survive almost entirely on consuming meat, while plants and phytoplankton, which make their own food, are at the bottom of the scale. Humans, according to the new paper, currently fall in the middle: 2.21. However, rising meat-eating in countries like China, India, and Brazil is pushing our trophic level higher with massive environmental impacts.
Japan pledges to raise carbon emissions, instead of cutting them
(11/18/2013) In 2009, Japan pledged to cut its carbon emissions by 25 percent based on 1990 levels within 11 years. Four years later—including a nuclear meltdown at Fukushima—and Japan has reset its goal with a new target to cut emissions by 3.8 percent based on 2005 levels at the UN Climate Summit in Warsaw, Poland. But, the new target, which received widespread condemnation when announced on Friday, actually results in a 3.1 percent rise in emissions when viewed from the widely-accepted 1990 baseline.
CO2 concentrations hit new high last year
(11/06/2013) The concentrations of carbon dioxide in the atmosphere hit a record high last year, according to a new report by the World Meteorological Organization (WMO). While this was not a surprise given still-rising global emissions, the concentration rose significantly more than the average this decade. According to the WMO's annual greenhouse gas bulletin, CO2 concentrations hit 393.1 parts per million (ppm) in 2012.
France upholds nationwide ban on fracking
(10/14/2013) France's landmark ban on fracking has survived constitutional challenges lobbed by U.S.-company, Schuepbach Energy. On Friday, the nation's Constitutional Council decided that the ban did not violate France's constitution. Passed in 2011 under then President Nicolas Sarkozy, the ban has since been upheld by current President Francios Hollande.
Clock is ticking on fossil fuels: for first time IPCC scientists outline global carbon budget
(10/01/2013) The world's leading climate scientists have set out in detail for the first time how much more carbon dioxide humans can pour into the atmosphere without triggering dangerous levels of climate change—and concluded that more than half of that global allowance has been used up.
Global society must leave fossil fuels in the ground, unburnt, says top official
(09/26/2013) World governments must get used to the idea of leaving fossil fuel reserves in the ground unexploited and unburned, one of the world's most senior diplomats has said, ahead of a landmark report on climate science to be unveiled this Friday by the Intergovernmental Panel on Climate Change (IPCC). The former Irish president and UN high commissioner for human rights, Mary Robinson, is to spearhead a new international push aimed at breaking the climate talks deadlock and silencing skeptics, with a group of senior diplomats and politicians from around the world.
African grass could substantially cut greenhouse gas emissions from livestock industry
(09/17/2013) Scientists will call for a major push this week to reduce the amount of greenhouse gas emissions from agriculture through the use of a modified tropical grass. Brachiaria grasses have been found to inhibit the release of nitrous oxide, which has a more powerful warming effect than carbon dioxide or methane, leading them to be called a super grass.
China punishes top oil companies for failing to clean up their acts
(09/03/2013) China's top two oil companies have been penalized for missing pollution targets, reports China Central Television (CCTV). The Ministry of Environmental Protection has suspended all refinery projects for China National Petroleum Corporation (CPNC) and the China Petrochemical Corporation (Sinopec) until they meet their pollution targets. The move is a part of a wider crackdown on pollution across China, which has suffered from record air pollution.
Bad feedback: ocean acidification to worsen global warming
(08/28/2013) As if ocean acidification and climate change weren't troubling enough (both of which are caused by still-rising carbon emissions), new research published in Nature finds that ocean acidification will eventually exacerbate global warming, further raising the Earth's temperature.
Foodies eat lab-grown burger that could change the world
(08/06/2013) Yesterday at a press event in London, two food writers took a bite into the world's most unusual hamburger. Grown meticulously from cow stem cells, the hamburger patty represents the dream (or pipedream) of many animal rights activists and environmentalists. The burger was developed by Physiologist Mark Post of Maastricht University and funded by Google co-founder Sergey Brin in an effort to create real meat without the corresponding environmental toll.
Indigenous groups protest hydropower congress as controversy hits meeting in Malaysia
(05/22/2013) The opening of the International Hydropower Association (IHA) World Congress in the Malaysian state of Sarawak was marred today by indigenous protests and controversy after a local indigenous leader was barred from attending a pre-conference workshop. Over 300 people from local indigenous people protested the ongoing construction of around a dozen mega-dams in the state that threaten to flood traditional lands, force villages to move, and upend lives in the state. The Sarawak hydropower plans are some of the most controversial in the world—making the choice of Kuching, Sarawak for the IHA meeting an arguably ironic one—with critics contending that the dams are have been mired in political corruption, including kickbacks and bribes. IHA brings together dam builders, banks, and various related organizations worldwide every two years.
Eat insects to mitigate deforestation and climate change
(05/14/2013) A new 200-page-report by the UN Food and Agriculture Organization (FAO) urges human society to utilize an often-ignored, protein-rich, and ubiquitous food source: insects. While many in the industrialized west might turn up their noses at the idea of eating insects, already around 2 billion people worldwide eat over 1,900 species of insect, according to the FAO. Expanding insect-eating, the authors argue, may be one way to combat rising food needs, environmental degradation, and climate change.
A new world?: carbon dioxide concentrations in atmosphere hit 400 ppm
(05/11/2013) For the first time since homo sapiens evolved, concentrations of carbon dioxide in the atmosphere have struck 400 parts per million (ppm) due to burning fossil fuels. The National Oceanic and Atmospheric Administration (NOAA) reports that readings of carbon dioxide at Mauna Loa Observatory in Hawaii hit the symbolic number on Thursday and are expected to continue rising in coming years. The last time concentrations were this high for a sustained period was 4-5 million years ago when sea levels were 5-40 meters higher than today and the poles were 10 degrees Celsius hotter. During this epoch, forests grew along the shores of the Arctic Ocean and coral reefs were almost wholly absent.
What if companies actually had to compensate society for environmental destruction?
(04/29/2013) The environment is a public good. We all share and depend on clean water, a stable atmosphere, and abundant biodiversity for survival, not to mention health and societal well-being. But under our current global economy, industries can often destroy and pollute the environment—degrading public health and communities—without paying adequate compensation to the public good. Economists call this process "externalizing costs," i.e. the cost of environmental degradation in many cases is borne by society, instead of the companies that cause it. A new report from TEEB (The Economics of Ecosystems and Biodiversity), conducted by Trucost, highlights the scale of the problem: unpriced natural capital (i.e. that which is not taken into account by the global market) was worth $7.3 trillion in 2009, equal to 13 percent of that year's global economic output.
China to phase out super greenhouse gas
(04/24/2013) Some eight billion tonnes of greenhouse gases could be kept out of the atmosphere if China sticks to a deal with the United Nation's Montreal Protocol to eliminate the production of hydro-fluorocarbons (HCFCs). In return for phasing out HCFC production by 2030, the Multilateral Fund of the Montreal Protocol on Substances has promised China of funding up to $385 million.
U.S. CO2 emissions fall to lowest level since 1994
(04/05/2013) Carbon dioxide emissions from energy consumption in the United States during 2012 fell to the lowest level since 1994, finds a new report from the U.S. Energy Information Administration, a branch of the Department of Energy.
Proposed coal plant threatens Critically Endangered Philippine cockatoo
(04/02/2013) One kilometer off the Philippine island of Palawan lies the Rasa Island Wildlife Sanctuary; here forest grows unimpeded from a coral island surrounded by mangroves and coral reefs. Although tiny, over a hundred bird species have been recorded on the island along with a major population of large flying foxes, while in the waters below swim at least 130 species of coral fish, three types of marine turtles, and that curious-looking marine mammal, dugongs. Most importantly, perhaps, the island is home to the world's largest population of Philippine cockatoos (Cacatua haematuropygia), currently listed as Critically Endangered. But, although uninhabited by people, Rasa Island may soon be altered irrevocably by human impacts.
Near-record jump in carbon concentrations in global atmosphere last year
(03/06/2013) Carbon dioxide now makes up around 395 parts per million in the atmosphere, according to new data from the National Oceanic Atmospheric Administration (NOAA). Measuring atmospheric carbon in Mauna Loa, Hawaii, the NOAA notes that last year saw a jump of 2.67 parts per million, second only to a record jump in carbon concentrations in 1998—2.93 parts per million. The news further dampens hopes that nations will stick to their goal of keeping global temperatures from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
Good news about climate change? Evolving technology could make cleaning the air more profitable than fouling it
(02/26/2013) In the wake of the hottest and driest summer in memory throughout much of North America, and Super-storm Sandy that flooded cities and ravaged large swaths of the Mid-Atlantic coast, many now recognize that the climate change isn’t just real, but that it is already at our doorstep. As this realization continues to sink in, the political will may ripen to take more aggressive action to put a brake CO2 emissions. Already, President Obama, who had remained mostly silent on the issue during his reelection campaign, has made it clear that tackling climate change will be among his top second-term priorities. But the fact remains that even if the entire world switched magically to 100 percent solar and other non-polluting power sources tomorrow, it’s too late to roll back some of the impacts of climate change.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Climate Summit in Doha characterized by lack of ambition
(12/09/2012) Ahead of the 18th United Nations Framework Convention on Climate Change (UNFCCC) in Doha, Qatar a variety of reports warned that the world was running out of time to avoid dangerous climate change, and that there was a widening gap between what nations have pledged to do and what the science demanded. A landmark report by the World Bank painted an almost apocalyptic picture of a world in which global temperatures have risen 4 degrees Celsius above pre-industrial levels, including unprecedented heatwaves and droughts, rising sea levels, global agriculture crises, and a stunning loss of species. In addition, scientific studies released near the two week conference found that sea levels were rising 60 percent faster than predicted, forests around the world were imperiled by increasing drought, marine snails were dissolving in the Southern Ocean due to ocean acidification, and ice melt in Greenland and Antarctica was on the rise.
Organic farming keeps carbon out of the atmosphere
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
Unique program to leave oil beneath Amazonian paradise raises $300 million
(11/26/2012) The Yasuni-ITT Initiative has been called many things: controversial, ecological blackmail, revolutionary, pioneering, and the best chance to keep oil companies out of Ecuador's Yasuni National Park. But now, after a number of ups and downs, the program is beginning to make good: the Yasuni-ITT Initiative has raised $300 million, according to the Guardian, or 8 percent of the total amount needed to fully fund the idea.
As Doha Climate Summit kicks off, more ambitious cuts to greenhouse gas emissions needed
(11/26/2012) As the 18th meeting of the UN Framework Convention on Climate Change (UNFCCC) kicks off this morning in oil and gas rich Qatar, the world body warns that much more ambitious greenhouse gas cuts are needed to keep catastrophic climate change at bay. A new report by the UN Environment Program (UNEP) and the European Climate Foundation finds that even if all current emissions pledges are kept, the world will still spew 8 billion tonnes of CO2 equivalent above what is needed by 2020, putting the globe on a fast-track to dangerous climate change.
Hotter and hotter: concentrations of greenhouse gases hit another new record
(11/20/2012) As expected, greenhouse gas concentrations in the Earth's atmosphere hit another record last year, according to a new UN World Meteorological Organization (WMO). The increasing concentrations of greenhouse gases means that radiative forcing—changes in the atmosphere's energy balance that leads to warming—has jumped 30 percent in the last twenty years.
Charts: comparing the largest carbon emitters
(08/12/2012) Earlier this month the U.S. Department of Energy's Energy Information Administration announced an 8 percent drop in U.S. carbon dioxide emissions during the first quarter of 2012. Emissions between January and March 2012 were the lowest since 1992.
Earth's ecosystems still soaking up half of human carbon emissions
(08/06/2012) Even as humans emit ever more carbon dioxide into the atmosphere, Earth's ecosystems are still sequestering about half, according to new research in Nature. The study finds that the planet's oceans, forests, and other vegetation have stepped into overdrive to deal with the influx of carbon emitted from burning fossil fuels, but notes that this doesn't come without a price, including the acidification of the oceans.
Prominent climate skeptic reverses course, says global warming worse than IPCC forecast
(07/30/2012) After starting his own project to study global warming, a once-prominent climate change skeptic and physicist says he now accepts the reality of anthropogenic climate change. "Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause," Richard Muller writes in the New York Times as his team, the Berkeley Earth Project, releases a new paper that finds an even stronger link between greenhouse gas emissions and rising temperatures worldwide than the Intergovernmental Panel on Climate Change (IPCC).
Scientists: iron fertilization could be a big climate help
(07/18/2012) For a long time, oceanic iron fertilization was seen as a promising mechanism to combat global climate change. But then in 2009 a well-publicized study found that iron fertilization stored 80 times less carbon than expected, dampening enthusiasm and support around the geoengineering scheme. Now, however, the idea of fertilizing the ocean with iron may be back: a new study in Nature reports that iron fertilization, in the right conditions, could store carbon in the deep ocean for centuries.
Warmer forests expel carbon from soils creating "vicious cycle"
(06/13/2012) As the world warms, temperate forests could become a source of carbon dioxide emission rather than a sink according to a new study in the Proceedings of the National Academy of Sciences (PNAS). Scientists found that two forest sites in the U.S. (Wisconsin and North Carolina) emitted long-stored carbon from their soils when confronted with temperatures 10-20 degrees Fahrenheit (5.5-11.1 degrees Celsius) higher than average.
Scientists: if we don't act now we're screwed
(06/07/2012) Scientists warn that the Earth may be reaching a planetary tipping point due to a unsustainable human pressures, while the UN releases a new report that finds global society has made significant progress on only four environmental issues out of ninety in the last twenty years. Climate change, overpopulation, overconsumption, and ecosystem destruction could lead to a tipping point that causes planetary collapse, according to a new paper in Nature by 22 scientists. The collapse may lead to a new planetary state that scientists say will be far harsher for human well-being, let alone survival.
Carbon dioxide hits 400 parts per million in Northern Hemisphere
(05/31/2012) Concentrations of carbon dioxide in the atmosphere have risen above 400 parts per million (ppm) in recording stations across the Arctic going as far south as Mongolia, reports the Associated Press. Such levels have not been seen in at least 800,000 years according to researchers. Carbon levels fluctuate depending on the region and the season and scientists say global concentrations will likely remain at around 395 ppm for the time being.
Charting a new environmental course in China
(05/21/2012) Founded in 1951, The Nature Conservancy (TNC) works in more than 30 countries and has projects in all 50 of the United States. The Conservancy has over one million members, and has protected more than 119 million acres of wild-lands and 5,000 miles of rivers worldwide. TNC has taken an active interest in China, the world's most populated nation, and in many important ways, a critical center of global development. The following is an interview with multiple directors of The Nature Conservancy's China Program.
Featured video: why one scientist is getting arrested over climate change
(05/16/2012) In March 2012 the head of NASA's Goddard Institute for Space Studies and well-known climatologist, James Hansen, spoke at a TED conference to explain what would push a 70-year-old scientist to participate in civil disobedience against mountaintop coal mining and the Keystone Pipeline, even leading to several arrests.
13 arrested for blockading coal train, including Nobel Prize winning economist
(05/07/2012) Thirteen Canadians were peacefully arrested this weekend for blockading Burlington Northern Santa Fe (BNSF) Railway train tracks in order to prevent the passage of coal stemming from the United States and destined to be burned in Asia. Among those arrested was Mark Jaccard, an economics professor with Simon Fraser University, who won the Nobel Prize for his work with the Intergovernmental Panel on Climate Change (IPCC).
Mexico passes aggressive climate bill
(04/23/2012) Last week, Mexico's Senate passed an aggressive and comprehensive climate change bill, making it the first developing nation and only the second country to do so, after the UK. The bill, which far outshines anything achieved by its far wealthier northern neighbors, sets ambitious targets for cutting emissions while creating new incentive programs for clean energy. Largely dependent on fossil fuels, Mexico is approximately the 11th highest greenhouse gas emitter in the world.
For Earth Day, 17 celebrated scientists on how to make a better world
(04/22/2012) Seventeen top scientists and four acclaimed conservation organizations have called for radical action to create a better world for this and future generations. Compiled by 21 past winners of the prestigious Blue Planet Prize, a new paper recommends solutions for some of the world's most pressing problems including climate change, poverty, and mass extinction. The paper, entitled Environment and Development Challenges: The Imperative to Act, was recently presented at the UN Environment Program governing council meeting in Nairobi, Kenya.
Scientists say massive palm oil plantation will "cut the heart out" of Cameroon's rainforest
(03/15/2012) Eleven top scientists have slammed a proposed palm oil plantation in a Cameroonian rainforest surrounded by five protected areas. In an open letter, the researchers allege that Herakles Farm, which proposes the 70,000 hectare plantation in southwest Cameroon, has misled the government about the state of the forest to be cleared and has violated rules set by the Roundtable on Sustainable Palm Oil (RSPO), of which it's a member. The scientists, many of whom are considered leaders in their field, argue that the plantation will destroy rich forests, imperil endangered species, and sow conflict with local people.
Featured Video: the true cost of the tar sands
(03/15/2012) What's the big deal about the tar sands? Canadian photographer Garth Lenz presents the local environmental and social concerns presented by the tar sands in a concise, impassioned speech in a TEDx talk in Victoria, Canada.
Tar sands emit more carbon than previously estimated
(03/12/2012) Environmentalists have targeted the oil-producing tar sands in Canada in part because its crude comes with heftier carbon emissions than conventional sources. Now, a new study in the Proceedings of the National Academy of Sciences (PNAS) has found an additional source of carbon that has been unaccounted for: peatlands. Mining the oil in the tar sands, dubbed "oil sands" by the industry, will require the wholesale destruction of nearly 30,000 hectares of peatlands, emitting between 11.4 and 47.3 million metric tons of additional carbon.
Carbon emissions paving way for mass extinction in oceans
(03/05/2012) Human emissions of carbon dioxide may be acidifying the oceans at a rate not seen in 300 million years, according to new research published in Science. The ground-breaking study, which measures for the first time the rate of current acidification compared with other occurrences going back 300 million years, warns that carbon emissions, unchecked, will likely lead to a mass extinction in the world's oceans. Acidification particularly threatens species dependent on calcium carbonate (a chemical compound that drops as the ocean acidifies) such as coral reefs, marine mollusks, and even some plankton. As these species vanish, thousands of others that depend on them are likely to follow.
Investigation links APP to illegal logging of protected trees
(03/01/2012) A year-long undercover investigation has found evidence of Asia Pulp and Paper (APP) companies cutting and pulping legally protected ramin trees, a practice that violates both Indonesian and international law. Found largely in Sumatra's peatswamp forests, the logging of ramin trees (in the genus Gonystylus) has been banned in Indonesia since 2001; the trees are also listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) and thus require special permits to export. The new allegations come after APP, an umbrella paper brand, has lost several customers due to its continued reliance on pulp from rainforest and peatland forests in Sumatra.
TransCanada to build southern half of Keystone to avoid State Department approval
(02/29/2012) Keystone XL is becoming the project that refuses to die: TransCanada, the company behind the pipeline, has said it plans to build the southern half of the pipeline while it waits to determine a new route for the northern section. The company does not need approval from the State Department, which turned down the entire pipeline in January, to build the southern half from Texas to Oklahoma. However, the Obama Administration has embraced the idea. Carrying carbon-intensive tar sands oil down from Canada to a global market, the proposed pipeline galvanized environmental and climate activists last year, resulting in several large protests and civil disobedience actions.
Six nations, including U.S., set up climate initiative to target short-term greenhouse gases
(02/20/2012) With global negotiations to tackle carbon emissions progressing interminably, nations are seeking roundabout ways to combat global climate change. U.S. Secretary of State, Hillary Clinton, announced in India last week a new six nation initiative to target non-carbon greenhouse gases, including soot (also known as "black carbon"), methane, and hydro-fluorocarbons (HFCs). Reductions of these emissions would not only impact short-term climate change, but also improve health and agriculture worldwide according to a recent study in Science.
Activists form network to fight Sarawak dam-building spree
(02/15/2012) Last October indigenous groups, local people, and domestic NGOs formed the Save Sarawak's Rivers Network to fight the planned construction of a dozen dams in the Malaysian state on the island of Borneo. The coalition opposes the dam-building plans, known as the Sarawak Corridor of Renewable Energy (SCORE) initiative, due to its impacts on indigenous and river communities, the destruction of pristine rainforest, and the degradation of the state's rivers.
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.
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).
US provides 3 billion in subsidies for Exxon-mobil project in Papua New Guinea
(12/10/2009) While officials from around their world are working night-and-day to come up with an international agreement to combat climate change in Copenhagen, the US Export-Import Bank confirmed it will subsidize a natural gas project in Papua New Guinea to the tune of 3 billion dollars—a record for the bank.
