(12/01/2009) If you’re a world leader and you won’t be in Copenhagen next week you might feel out of the loop. Currently 98 heads of state have agreed to attend the Climate Change Summit in Copenhagen—nearly half of the 192 member nations of the UN.
World requires radical new economic models to fight poverty and mitigate global warming
(11/30/2009) A new report calls for a radical re-envisioning of current economic models in order to tackle poverty, mitigate and adapt to climate change, and solve other environmental problems. The report was crafted by the New Economics Foundation (NEF) and the International Institute for Environment and Development (IIED) and was supported by The Working Group on Climate Change and Development, which includes a wide variety of well-known groups, including environmental, religious, and anti-poverty organizations.
What would the Dalai Lama do?: spiritual leader speaks out on climate change
(11/30/2009) The Dalai Lama has given up taking baths in favor of showers and makes certain all lights are off when he leaves a room to help lower his carbon footprint, he told a crowd of reporters in Sydney Australia today.
Americans throw away enough food every year to feed 200 million adults
(11/30/2009) The amount of food Americans throw away has risen by approximately 50 percent since 1974 according to a new study in PLoS ONE. American now waste on average 1400 calories per person everyday, equaling 150 trillion calories a year nationwide. Considering that the average person requires approximately 2,000 calories a day, this means that the US could feed over 200 million adults every year with the food that ends up in the trash. Currently, the UN estimates that one billion people—an historical record—are going hungry worldwide.
Zoos call for deeper emission cuts to save life on Earth
(11/30/2009) To save species around the world zoos say deeper emission cuts are needed than governments are currently proposing. Over 200 zoos worldwide have signed a petition calling on governments to set the target of atmospheric carbon below 350 parts per million (ppm) far lower than most government targets.
Reforestation effort would lower Britain's greenhouse gas emissions by 10 percent
(11/25/2009) A study by Britain's Forestry Commission found that planting 23,000 hectares of forest every year for the next 40 years would lower the island nation's greenhouse gas emissions by 10 percent, according to reporting by the BBC.
Land of plenty: 50 percent rise in the amount of food wasted in America worsens global warming, consumes freshwater
(11/25/2009) Just before Thanksgiving a new study shows that Americans are throwing away more food than ever. Since 1974 the amount of food Americans water per capita has risen by approximately 50 percent, according to a new study in PLoS ONE. Researchers found that food waste is adding to America's greenhouse gas emissions and accounts for over one quarter of the nation's freshwater consumption every year.
The US will set emissions target, but is this a turning point for success at Copenhagen?
(11/24/2009) Today may mark a turning point for a successful negotiation at the Climate Change Summit in Copenhagen or it may just be another blip in the up-and-down news cycles that have preceded the summit for months.
Efforts to slow climate change may put indigenous people at risk
(11/24/2009) Efforts to slow climate change are putting indigenous people at risk, warns a new report published by Survival International, an indigenous rights' group.
Global warming will increase likelihood of civil war in Africa by 55 percent
(11/23/2009) There have been many warnings by policymakers that rising temperatures in Africa could lead to civil conflict, however a new study in Proceedings of the National Academy of Sciences is the first to uncover empirical evidence for these warnings and quantify them. The results—that higher temperatures increased the likelihood of civil war in sub-Saharan Africa by over 50 percent—took aback even the researchers.
Deforestation emissions should be shared between producer and consumer, argues study
(11/19/2009) Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.
Oceans' ability to sequester carbon diminishing
(11/18/2009) A new study—the first of its kind—has completed an annual accounting of the oceans' intake of carbon over the past 250 years, and the news is troubling. According to the study, published in Nature, the oceans' ability to sequester carbon is struggling to keep-up with mankind's ever-growing emissions. Since 2000 researchers estimate that while every year the oceans continue to sequester more anthropogenic carbon emission, the overall proportion of carbon taken in by the oceans is declining.
Record year for CO2 emissions, even with economic slowdown
(11/17/2009) 8.7 billion tons of carbon dioxide was emitted into the earth's atmosphere in 2008, a growth of 2 percent despite the economic crisis. This averages out to each person contributing a record high of 1.3 tons of carbon, according to a report in the journal Nature Science. While the global recession slowed the growth of fossil fuel emissions for the first time this decade, it did not lower emissions altogether.
Coastal habitats may sequester 50 times more carbon than tropical forests by area
(11/16/2009) Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marshes—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."
Holding the Global North Responsible for Climate Change: What Would Lord Russell Do?
(11/16/2009) If Lord Bertrand Russell were still alive today, he would most likely be appalled by the Global North’s glaring inaction on climate change. One of the twentieth century’s most eminent philosophers, Russell was also an outspoken critic of war and irrationality. In 1966, just as the United States was ramping up the war in Vietnam, Russell helped to establish a novel legal tribunal which condemned war crimes committed in South East Asia.
Asia-Pacific leaders drop emissions cuts from Copenhagen agenda
(11/16/2009) Leaders of the 21-member Asia Pacific Economic Cooperation (APEC) dropped the reference to greenhouse gas emissions cuts from their declaration released Sunday, reports Reuters.
Brazil pledges to restrain emissions growth
(11/15/2009) In a move that some observers say could provide a path forward on a future climate agreement that includes emissions cuts in developing countries, Brazilian President Luiz Inacio Lula da Silva said his country will aim to reduce emissions 14 to 19 percent below 2005 levels by 2020.
New rating systems seeks to promote sustainable landscapes from shopping malls to city parks
(11/15/2009) The Sustainable Sites Initiative has developed the United States' first rating system for the design, construction, and on-going maintenance of a wide-variety of landscapes, both with and without buildings, including shopping malls, subdivisions, university campuses, corporate buildings, transportation centers, parks and other recreation areas, and single-family homes.
Countries that invest in conservation will see higher financial returns, argues report
(11/13/2009) A new report issued by the The Economics of Ecosystems and Biodiversity (TEEB) initiative makes a strong case for valuing the planet's ecosystem services. The report calls for investments in "ecological infrastructure" to protect wildlands and the services they provide; market-based valuation of ecosystem services; reductions in environmentally harmful subsidies; recognition of the link between environmental degradation and poverty; and a strong climate deal that includes forest carbon.
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?
Hunting across Southeast Asia weakens forests' survival, An interview with Richard Corlett
(11/08/2009) A large flying fox eats a fruit ingesting its seeds. Flying over the tropical forests it eventually deposits the seeds at the base of another tree far from the first. One of these seeds takes root, sprouts, and in thirty years time a new tree waits for another flying fox to spread its speed. In the Southeast Asian tropics an astounding 80 percent of seeds are spread not by wind, but by animals: birds, bats, rodents, even elephants. But in a region where animals of all shapes and sizes are being wiped out by uncontrolled hunting and poaching—what will the forests of the future look like? This is the question that has long occupied Richard Corlett, professor of biological science at the National University of Singapore.
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.
NASA satellite image reveals extent of drought in East Africa
(11/05/2009) A new image from NASA shows the severity of the drought in East Africa, which impacted Tanzania, Kenya, Ethiopia, and Somalia.
Governments, public failing to save world's species
(11/04/2009) According to the International Union for the Conservation of Nature's (IUCN) 2008 report, released yesterday, 36 percent of the total species evaluated by the organization are threatened with extinction. If one adds the species classified as Near Threatened, the percentage jumps to 44 percent—nearly half.
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.
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.
Goodbye, snows of Kilimanjaro
(11/02/2009) The most recent survey among the ice fields atop Mount Kilimanjaro found that the ice atop Africa's most famous mountain could be gone in twenty years—and maybe even sooner. Published in the Proceedings of the National Academy of Science the study was conducted by a team of researchers who first measured the glaciers in 2000. They discovered that between 1912 and 2007, 85 percent of the ice that covered Mount Kilimanjaro vanished. When using 2000 as baseline the mountain has lost 26 percent of its ice.
Will Ecuador's plan to raise money for not drilling oil in the Amazon succeed?
(10/27/2009) Ecuador's Yasuni National Park is full of wealth: it is one of the richest places on earth in terms of biodiversity; it is home to the indigenous Waorani people, as well as several uncontacted tribes; and the park's forest and soil provides a massive carbon sink. However, Yasuni National Park also sits on wealth of a different kind: one billion barrels of oil remain locked under the pristine rainforest.
Logged forests support biodiversity after 15 years of rehabilitation, but not if turned into plantations
(10/21/2009) With the world facing global warming and a biodiversity crisis, a new study shows that within 15 years logged forests—considered by many to be 'degraded'—can be managed in order to successfully fight both climate change and extinction.
Kenya's pain, part two: decades of wildlife decline exacerbated by drought
(10/20/2009) Not many years ago if you were planning a trip to Africa to see wildlife, Kenya would be near the top of the list, if not number one. Then violent riots in late 2007 and early 2008 leaving a thousand dead tarnished the country's image abroad. When calm and stability returned, Kenya was again open for tourism, and it's true that most travelers were quick to forget: articles earlier this year announced that even with the global economic crisis Kenya was expecting tourism growth. However, a new disaster may not be so quickly overcome.
Arctic lake undergoing unprecedented changes due to warming
(10/19/2009) The Arctic should be growing cooler, but a new sediment core taken from an Arctic lake reveals that the lake's ecology and chemistry has been transformed by unnatural warming beginning in the 1950s. The sediment core proves that changes happening in the lake during the Twentieth Century are unprecedented over the past 200,000 years. Headed by University of Colorado scientist Yarrow Axelford, the study retrieved the sediment core from the bottom of a thirty foot deep lake on Baffin Island. Importantly the sediment core goes back 80,000 years further than any other core retrieved from the Greenland ice sheet, providing researchers with the longest timescale yet of changes in the Arctic climate.
Present day tropical plant families survived in warmer, wetter tropics 58 million years ago
(10/18/2009) Fifty eight million years ago the tropical rainforests of South America shared many similarities with today's Neotropical forests, according to research published in the Proceedings of the National Academy of Sciences. Looking at over 2,000 fossils in Colombia from one of the world's largest open pit coal mines, scientists were able to recreate for the first time the structure of a long vanished rainforest. One inhabited by a titanic snake, giant turtles, and crocodile-like reptiles.
TV worthless when it comes to knowledge about global warming
(10/18/2009) Is TV your top media choice? Then its likely, according to new research, that climate change is largely off your radar.
Freshwater species worse off than land or marine
(10/15/2009) Scientists have announced that freshwater species are likely the most threatened on earth. Extinction rates for freshwater inhabitants are currently four to six times the rates for terrestrial and marine species. Yet, these figures have not lead to action on the ground.
Business and conservation groups team up to conserve and better manage US's southern forests
(10/15/2009) A new project entitled Carbon Canopy brings together multiple stakeholders—from big business to conservation organizations to private landowners—in order to protect and better manage the United State's southern forests. The program intends to employ the emerging US forest carbon market to pay private forest owners for conservation and restoration efforts while making certain that all forest-use practices subscribes to the standards of the Forest Stewardship Council (FSC).
Global Day of Climate Action Approaches
(10/06/2009) As part of an ongoing international campaign to raise awareness of the severity of climate change and solutions, Bill McKibben's 350 movement is preparing for a massive worldwide day of action. Over 1,600 individual events have been planned in at least 128 countries.
Could agroforestry solve the biodiversity crisis and address poverty?, an interview with Shonil Bhagwat
(09/24/2009) With the world facing a variety of crises: climate change, food shortages, extreme poverty, and biodiversity loss, researchers are looking at ways to address more than one issue at once by revolutionizing sectors of society. One of the ideas is a transformation of agricultural practices from intensive chemical-dependent crops to mixing agriculture and forest, while relying on organic methods. The latter is known as agroforestry or land sharing—balancing the crop yields with biodiversity. Shonil Bhagwat, Director of MSc in Biodiversity, Conservation and Management at the School of Geography and the Environment, Oxford, believes this philosophy could help the world tackle some of its biggest problems.
Will tropical trees survive climate change?, an interview with Kenneth J. Feeley
(09/24/2009) One of the most pressing issues in the conservation today is how climate change will affect tropical ecosystems. The short answer is: we don't know. Because of this, more and more scientists are looking at the probable impacts of a warmer world on the Earth's most vibrant and biodiverse ecosystems. Kenneth J. Feeley, tropical ecologist and new professor at Florida International University and the Center for Tropical Plant Conservation at the Fairchild Tropical Botanic Garden, is conducting groundbreaking research in the tropical forests of Peru on the migration of tree species due to climate change.
Satellite lasers show melting of Greenland, Antarctic worse than expected
(09/23/2009) Researchers examining 43 million satellite measurements of Antarctica's thinning ice sheets and 7 million of Greenland's, show that the ice is melting faster than expected. Published in Nature the research is the most comprehensive picture to date of the melting glaciers, allowing scientists to better predict how sea levels may rise.
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.
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.
Fashion labels drop APP after party highlights the plight of Indonesian forests
(09/21/2009) The fashion world has been rocked: not by the newest designer or the most shocking outfit, but by the continuing destruction of forests in Indonesia. On September 15th, the Rainforest Action Network (RAN) helped open New York City's styling Fashion Week with a party to encourage fashion designers to take a closer look at the paper bags they give customers.
Kenya's pain: famine, drought, government ambivalence cripples once stable nation
(09/17/2009) Kenya was once considered one of Sub-Saharan Africa's success stories: the country possessed a relatively stable government, a good economy, a thriving tourist industry due to a beautiful landscape and abundant wildlife. But violent protests following a disputed election in 2007 hurt the country's reputation, and then—even worse—drought and famine struck the country this year. The government response has been lackluster, the international community has been distracted by the economic crisis, and suddenly Kenya seems no longer to be the light of East Africa, but a warning to the world about the perils of ignoring climate change, government corruption, and the global food and water shortages.
Alleviating poverty and saving biodiversity are inherently linked argue scientists
(09/17/2009) Twenty-nine scientists argue in Science today that the world will not be able to lift up the world's poor unless it also addresses global biodiversity loss. They say that the same underlying problems—exploitation of resources, unsustainable overconsumption, climate change, population growth—are exacerbating global poverty and the extinction of species.
