(08/20/2013) On a cross-country bus trip through the American Midwest, I watch cool morning mist rise from patchwork fields. Between the fields stand groves of dark green mid-summer trees, I am reminded that this scene is in jeopardy. The region is cited for its vulnerability to desertification associated with climate change.
Drastic cuts to greenhouse gases could save hundreds of U.S. cities from watery grave
(08/01/2013) More than 1,700 American cities and towns – including Boston, New York, and Miami – are at greater risk from rising sea levels than previously feared, a new study has found. By 2100, the future of at least part of these 1,700 locations will be "locked in" by greenhouse gas emissions built up in the atmosphere, the analysis published in the Proceedings of the National Academy of Sciences on Monday found.
Panel lays out best practices for REDD+ credits in California's carbon market
(07/19/2013) A panel of scientific experts has released a final report outlining how carbon credits generated from tropical forest conservation could be used under California's cap-and-trade system while minimizing risks to forest-dependent communities and wildlife.
In age of climate change, Australia's vast coal fields could become worthless
(07/02/2013) Australia's huge coal industry is a speculative bubble ripe for financial implosion if the world's governments fulfill their agreement to act on climate change, according to a new report. The warning that much of the nation's coal reserves will become worthless as the world hits carbon emission limits comes after banking giant Citi also warned Australian investors that fossil fuel companies could do little to avoid the future loss of value.
After long wait, Obama lays out fight against climate change
(06/25/2013) Five years after being elected president and six months after winning a second term, President Obama today gave his first speech devoted solely to climate change and announced several executive actions to begin weaning the United States (historically the largest emitter of greenhouse gases) off fossil fuels. At Georgetown University today, Obama stated that his administration would expand renewable energy projects on federal lands, raise energy efficiency standards on appliances, and, most importantly, limit carbon pollution from both existing and new power plants, which represent about 40 percent of the U.S.'s emissions. Obama also noted that the U.S. would spearhead global efforts to combat climate change which is pushing sea levels higher, melting glaciers and sea ice, exacerbating fires, imperiling species, and worsening extreme weather worldwide.
Should zoos educate the public about climate change?
(06/18/2013) Zoos are usually thought of as entertainment destinations. As a place to take the kids on a nice afternoon, they are sometimes perceived to lack the educational heft of an art museum or a theatre. However, over the past few decades many of the world's best zoos and aquariums have also worked to educate their visitors about conservation issues, in addition to funding and supporting programs in the field to save the ever-growing number of imperiled species. But as threats to the world's species mount—including climate change—many are beginning to ask what, if anything, zoos and aquariums should do to address the global environmental crisis.
Canadian province cancels tar sands pipeline due to environmental impact
(06/04/2013) Efforts to expand production from the Alberta tar sands suffered a significant setback on Friday when the provincial government of British Columbia rejected a pipeline project because of environmental shortcomings. In a strongly worded statement, the government of the province said it was not satisfied with the pipeline company's oil spill response plans.
Market for REDD+ carbon credits declines 8% in 2012
(05/30/2013) The market for carbon credits generated from projects that reduce deforestation and forest degradation — a climate change mitigation approach known as REDD+ — dipped eight percent in 2012 according to an annual assessment of the global voluntary carbon market.
China to begin cutting carbon emissions one city at a time
(05/23/2013) China has unveiled details of its first pilot carbon-trading program, which will begin next month in the southern city of Shenzhen. The trading scheme will cover 638 companies responsible for 38% of the city's total emissions, the Shenzhen branch of the powerful National Development and Reform Commission (NDRC) announced on Wednesday. The scheme will eventually expand to include transportation, manufacturing and construction companies.
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.
Debate heats up over California's plan to reduce emissions via rainforest protection
(05/07/2013) As the public comment period for California's cap-and-trade program draws to a close, an alliance of environmental activists have stepped up a heated campaign to keep carbon credits generated by forest conservation initiatives in tropical countries out of the scheme. These groups say that offsets generated under the so-called Reducing Emissions from Deforestation and Degradation (REDD+) mechanism, will undermine efforts to cut emissions as home, while potentially leading to abuses abroad. However supporters of forest conservation-based credits say the program may offer the best hope for saving the world's beleaguered rainforests, which continue to fall at a rate of more than 8 million hectares per year.
Climate Myths: how climate denialists are getting away with bad science
(04/29/2013) In Climate Myths: The Campaign Against Climate Science, Dr. John J. Berger deconstructs the climate change denialists' myths in simple, easy-to-read terms. According to the Pew Research Center: "Nearly seven-in-ten (69%) [Americans] say there is solid evidence that the earth’s average temperature has been getting warmer over the past few decades, up six points since November 2011 and 12 points since 2009." Yet implementing national-level climate change mitigation legislation is not occurring in the U.S.
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.
'Carbon bubble' could cause next global financial crisis
(04/22/2013) The world could be heading for a major economic crisis as stock markets inflate an investment bubble in fossil fuels to the tune of trillions of dollars, according to leading economists. "The financial crisis has shown what happens when risks accumulate unnoticed," said Lord (Nicholas) Stern, a professor at the London School of Economics. He said the risk was "very big indeed" and that almost all investors and regulators were failing to address it.
Fighting deforestation—and corruption—in Indonesia
(04/11/2013) The basic premise of the Reducing Emissions from Deforestation and Degradation (REDD+) program seems simple: rich nations pay tropical countries for preserving their forests. Yet the program has made relatively limited progress on the ground since 2007, when the concept got tentative go-ahead during U.N. climate talks in Bali. The reasons for the stagnation are myriad, but despite the simplicity of the idea, implementing REDD+ is extraordinarily complex. Still the last few years have provided lessons for new pilot projects by testing what does and doesn't work. Today a number of countries have REDD+ projects, some of which are even generating carbon credits in voluntary markets. By supporting credibly certified projects, companies and individuals can claim to "offset" their emissions by keeping forests standing. However one of the countries expected to benefit most from REDD+ has been largely on the sidelines. Indonesia's REDD+ program has been held up by numerous factors, but perhaps the biggest challenge for REDD+ in Indonesia is corruption.
U.S. Republican voters want action on climate change
(04/03/2013) A new poll by the Center for Climate Change Communication (4C) at George Mason University finds that a majority of U.S. citizens who identify as Republicans or Republican-leaning independents want the government to do more to tackles climate change. Sixty-two percent of those polled said that the U.S. government "absolutely should" or "probably should" takes steps to address climate change. This goes against the views of many Republican congressmen—as well as the party platform—who largely oppose action on climate change.
Scientists a step closer toward creating biofuels directly from atmospheric CO2
(03/29/2013) Researchers have taken a step closer to using atmospheric carbon dioxide as a biofuel, potentially helping mitigate climate change while at the same time meeting rising energy demand, according to a study published in the Proceedings of the National Academy of Sciences.
China may push geoengineering as solution to climate change
(03/26/2013) The political dilemma over geoengineering – deliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects – will perhaps be most acute in China.
Eruption yields bad news for iron fertilization-based geoengineering schemes
(03/22/2013) Geoengineering schemes that aim to slow global warming by seeding oceans with iron to boost carbon dioxide-absorbing phytoplankton may not lead to long-term sequestration of the important greenhouse gas, finds a new study published in the journal Geophysical Research Letters.
Planet organic: achieving sustainable food security and environmental gains
(03/19/2013) The global farmland area certified organic has expanded more than threefold to 37 million hectares since 1999, according to new research conducted by the Worldwatch Institute. The Institute argues that organic farming has the potential to contribute to sustainable food security by improving nutrition intake and sustaining rural livelihoods, while reducing vulnerability to climate change and enhancing biodiversity.
China delays carbon tax
(03/07/2013) China will not introduce a carbon tax in 2013, reports Bloomberg.
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.
Featured video: moving green, local energy forward in Southeast Asia
(02/25/2013) A new video highlights the work and drive of renewable energy proponents at the inaugural meeting of Southeast Asia Renewable Energy People’s Assembly (SEAREPA) in the Malaysian state of Sabah. Held last year, the meeting brought together 80 organizations from 12 countries to discuss the potential and challenges of green energy in the region. The idea of SEAREPA came about after activists in Sabah successfully defeated plans for a coal-fired power plant to be built adjacent to old-growth rainforest and one of the world's most biodiverse coral reefs.
China to tax carbon emissions
(02/20/2013) China will introduce a carbon tax, reports official state media.
Over 35,000 march on Washington demanding climate action and rejection of Canada's 'carbon bomb'
(02/18/2013) Yesterday over 35,000 people rallied in Washington D.C. for urgent action on climate change, which, according to organizers, was the largest climate march in U.S. history. Activists called on the Obama Administration to do much more to tackle climate change, including rejecting the Keystone XL Pipeline, which would bring carbon-heavy tar sands oil from Canada through the U.S. to a world market.
Obama connects climate science and policy in State of the Union
(02/13/2013) After several years of silence on climate change, U.S. President Barack Obama has begun speaking out following his re-election last November. The President surprised many by giving climate change a central role in his inauguration speech last month, and he followed-up in his State of the Union speech last night when he called on congress to "pursue a bipartisan, market-based solution to climate change," but added that the administration would take action itself if congress failed.
Carbon release, storage by rainforests may increase by 50b tons for each degree of climate warming in the tropics
(02/08/2013) Faster plant growth due to higher concentrations of carbon dioxide may offset increased emissions from forest die-off in the tropics, claims a new study based on climate modeling.
Experts outline how REDD+ credits could fit into California's cap-and-trade program
(01/27/2013) Carbon credits generated by forest conservation activities in tropical countries could play a role in California's cap-and-trade program, helping mitigate climate change and providing benefits to local communities, said a panel of experts on Friday.
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.
Biochar: a brief history and developing future
(01/02/2013) Biochar - charcoal produced from pyrolysis of biomass - has received tremendous attention and support in recent years, and championed as one of the potentially most useful techniques for soil restoration and carbon sequestration in the modern era. Although a multitude of initiatives in biochar research and application have sprung into action many critical details remain uncertain.
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.
'No-one is listening to the entire scientific community': global carbon emissions set to hit new high
(12/03/2012) Global carbon dioxide (CO2) emissions from industrial sources are set to hit a new record high this year according to a new analysis by Global Carbon Project. The analysis in Nature Climate Changes predicts that CO2 emissions will rise another 2.6 percent, hitting 35.6 billion tonnes. The scientists warn that such steep climbs in global emissions year-after-year means that the door is rapidly closing on a global agreement to keep temperatures from rising 2 degree Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
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.
Could marine cloud machines cool the planet?
(11/26/2012) In 1990, British cloud physicist John Latham published a paper arguing he could cool global climate by brightening clouds over the ocean. Most colleagues ignored the paper, titled 'Control global warming?'—probably because this thing called global warming was not yet a hot topic. Now, more than two decades later, Latham continues to develop what has become one of the most promising and controversial ideas in climate control. 'Marine cloud brightening' might sound benign, but hairs rise when it’s called 'geoengineering.'
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.
World Bank: 4 degrees Celsius warming would be miserable
(11/20/2012) A new report by the World Bank paints a bleak picture of life on Earth in 80 years: global temperatures have risen by 4 degrees Celsius spurring rapidly rising sea levels and devastating droughts. Global agriculture is under constant threat; economies have been hampered; coastal cities are repeatedly flooded; coral reefs are dissolving from ocean acidification; and species worldwide are vanishing. This, according to the World Bank, is where we are headed even if all of the world's nations meet their pledges on cutting greenhouse gas emissions. However, the report also notes that with swift, aggressive action it's still possible to ensure that global temperatures don't rise above 4 degrees Celsius.
REDD+ must consider biodiversity, forest livelihoods to have any chance of success
(11/16/2012) Safeguarding biodiversity is a critical component in any plan to mitigate climate change through forest protection, argues a comprehensive new assessment published by the International Union of Forest Research Organizations (IUFRO), the world’s largest network of forest scientists.
Micro-hydro and decentralized green energy goals set in Borneo
(11/04/2012) The first ever meeting of the Southeast Asia Renewable Energy People's Assembly (SEAREPA) ended with agreement on 12 future projects, including developing community micro-hydro power and pushing for new policies on decentralized renewable energy in the region. Held in Malaysian state of Sabah on the island, the meeting brought together 130 people from some 80 different groups.
After defeating coal plant, Borneo hosts renewable energy meeting
(10/31/2012) Last year, a coalition of environmentalists and locals won a David-versus-Goliath battle against a massive coal plant in the Malaysian state of Sabah on Borneo. After facing a protracted campaign—including expert analysis of green energy options for Sabah—the state government announced it was scuttling plans to build the coal plant on a beach overlooking the Coral Triangle. Now, victorious grassroots campaigners are hosting the inaugural meeting of the Southeast Asia Renewable Energy People’s Assembly (SEAREPA), bringing 80 organizations together to discuss green energy options across southeast Asia.
Will we need to pull carbon out of the atmosphere to save ourselves?
(10/17/2012) This year saw the Arctic sea ice extent fall to a new and shocking low, while the U.S. experienced it warmest month ever on record (July), beating even Dust Bowl temperatures. Meanwhile, a flood of new research has convincingly connected a rise in extreme weather events, especially droughts and heatwaves, to global climate change, and a recent report by the DARA Group and Climate Vulnerability Forum finds that climate change contributes to around 400,000 deaths a year and costs the world 1.6 percent of its GDP, or $1.2 trillion. All this and global temperatures have only risen about 0.8 degrees Celsius (1.44 degrees Fahrenheit) since the early Twentieth Century. Scientists predict that temperatures could rise between 1.1 degrees Celsius (2 degrees Fahrenheit) to a staggering 6.4 degrees Celsius (11.5 degrees Fahrenheit) by the end of the century.
United States ranks near bottom on first ever energy efficiency scorecard
(08/15/2012) Last month, the American Council for an Energy Efficient Economy released its first ever international energy efficiency scorecard, which gave the United Kingdom the top score. Using data points honed over years of rating U.S. states, the organization hoped to inspire nations to learn from each others' effective policies, as well as encourage "friendly competition" in the spirit of lowering global carbon emissions. At number one, the United Kingdom achieved a score of 67 out of 100 points, followed by Germany, Italy and Japan. As a whole, the European Union tied with China and Australia, and nine points below them, the United States came in with a score of 47 out of 100.
Climate and culture: abrupt change and rapid response
(08/06/2012) As the world experiences record heat, increased drought and fires, unprecedented ice melt and similar extreme weather anomalies decades before expected, climatologists have been forced to reconsider previous climate change projections and research techniques. Less than a decade ago, scientific consensus considered warming of more than 2 C and atmospheric levels of carbon dioxide near 450 parts per million (ppm) as acceptable or "safe". Revised climate science literature and expert opinion now regard safe atmospheric levels of carbon dioxide as below 350 ppm, or less than 1 C rise in average planetary temperature. Many researchers and environmentalists, however, recognize that the present deviation from pre-industrial temperatures of 0.8 C may be unacceptable to prevent runaway climate change and widespread disasters.
Mangroves should be part of solution to climate change
(08/02/2012) Mangroves are under-appreciated assets in the effort to slow climate change, argues a new Proceedings of the National Academy of Sciences paper which makes a argument for including the coastal ecosystems in carbon credit programs.
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.
Cowards at Rio?: organizations decry 'pathetic' agreement
(06/20/2012) As world leaders head to Rio de Janeiro for the UN Summit on Sustainable Development, environmental and poverty groups are denouncing the last-minute text agreed on by dignitaries as "pathetic," (Greenpeace), a "damp squib" (Friends of the Earth), "a dead end" (Oxfam), and, if nothing changes, "a colossal waste of time" (WWF). "We were promised the 'future we want' but are now being presented with a 'common vision' of a polluter’s charter that will cook the planet, empty the oceans and wreck the rain forests,“ the head of Greenpeace, Kumi Naidoo, said. "This is not a foundation on which to grow economies or pull people out of poverty, it’s the last will and testament of a destructive twentieth century development model."
Rio+20 and economic perils in Europe: opportunity for linkage
(06/19/2012) This month, momentous events will occur on the global scene that will set the tone for whether 2012 will be a hopeful year or one in which dislocations and disconnects are further exacerbated by political failings. The EU will decide on its fiscal and monetary union that hinges on Greece’s recent June election, which backed the political party that wants to stay in the Euro zone, but insists on adjustments to the earlier-negotiated economic rescue package.
Scientists give world leaders 'Fs' on climate change, biodiversity, and desertification
(06/19/2012) It seems world leaders may need to retake environmental studies. As the Rio+20 Summit on Sustainable Development opens, the scientific journal, Nature, has evaluated the progress made on three treaties signed at the Rio Earth Summit in 1992: climate change, biodiversity decline, and desertification. Unfortunately the publication gives progress on all three treaties an 'F', highlighting how little progress has been made on the global environmental crisis.
Experts: ignoring climate change at Rio+20 makes other goals "meaningless"
(06/18/2012) The Climate Change Task Force (CCTF)—made up of 30 climate scientists, other experts and world leaders—warned today that sidelining climate change at the Rio+20 Summit on Sustainable Development threatened progress on the conference's other goals, which includes combating poverty and building economies that value nature. "I am very concerned and worried because the draft final document of the Rio+20 conference does not give proper attention to climate change," says former Russian President Mikhail Gorbachev in a press statement.
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.
Want to stop climate change: buy fossil fuel deposits
(06/07/2012) Governments, NGOs, and others fighting climate change should consider buying coal and oil deposits—not to exploit them, but to keep them from being exploited, according to a bold new policy paper in the Journal of Political Economy. Economist Bard Harstad with the Kellogg School of Management argues that climate coalitions could quickly slash carbon emissions by purchasing and conserving marginal fossil fuel deposits, a strategy that would solve the current problem of carbon leakage, i.e. when cutting emissions in one place pushes others to burn more elsewhere. Given that carbon emissions rose to a new record last year—31.6 gigatons—and carbon has hit 400 parts per million (ppm) in the atmosphere for the first time in at least 800,000 years, Harstad's analysis comes at a time when scientists are warning that urgent and bold action is needed to mitigate global climate change before it becomes irreversible.
