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.
'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.
Carbon Management in the Built Environment - book review
(04/02/2013) Carbon Management in the Built Environment, written by Rohinton Emmanuel and Keith Baker, is the complete introductory textbook covering low carbon management for the built environment. Carbon Management in the Built Environment integrates climate change science, design, materials science, and policy into a classroom friendly text.
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.
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.
Burning coal may be killing over 100,000 people in India every year
(03/13/2013) India's dependence on coal-fired power plants for energy may be leading directly to the deaths of 80,000 to 115,000 of its citizens every year, according to the first ever report on the health impacts of coal in the country. The report, commissioned by the Conservation Action Trust and Greenpeace-India, deals only with the direct health impact of coal and not climate change. But even ignoring the rising pain of global warming, the bleak report outlines that coal consumption in India is causing over 20 million asthma attacks, nearly a million emergency room visits, and killing some 10,000 children under five annually.
China delays carbon tax
(03/07/2013) China will not introduce a carbon tax in 2013, reports Bloomberg.
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.
Rise in 1.5 degrees Celsius likely to spark massive greenhouse gas release from permafrost
(02/25/2013) While nations around the world have committed to keeping temperatures from rising 2 degrees Celsius (3.6 degrees Fahrenheit) above the pre-industrial era, new research published in Science suggests that the global climate could hit a tipping point at just 1.5 degrees Celsius (2.5 degrees Fahrenheit). Studying cave stalactites and stalagmites in Siberia, scientists found that at about 1.5 degrees Celsius the Siberian permafrost melts, potentially releasing a greenhouse gas bomb of 1,000 giga-tonnes, according to some experts.
Deforestation, wetlands loss in Brazil and Indonesia generated 45b tons of CO2 in 20 years
(02/22/2013) The United Nations Food and Agriculture Organization (FAO) has launched a global set of statistics on carbon emissions from deforestation, agriculture and other forms of land use for the 1990-2010 period.
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.
Palm oil, paper, biofuels production on peatlands drive large GHG emissions
(01/31/2013) Degradation of peat swamps for oil palm and timber plantations is a substantially larger source of greenhouse gas emissions than previously believed, finds a new study published in the journal Nature.
Soot is second biggest man-made contributor to global warming
(01/15/2013) Soot is the second largest man-made contributor to global warming, according to a comprehensive new study published in the Journal of Geophysical Research: Atmospheres.
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.
Fires burn over a third more land than estimated
(01/02/2013) Scientists currently detect fires around the world using moderate resolution satellite imagery, however a new study in the Journal of Geophysical Research finds that this tool misses many of the world's smaller fires, which add up.
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.
With deforestation falling, energy sector to become Brazil's biggest CO2 source
(12/03/2012) With its annual rate of deforestation falling more than 80 percent since 2004, energy is set to soon become Brazil's largest source of greenhouse gas emissions, reports a new study seen by Reuters.
'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.
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.
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.
Threatened Galapagos coral may predict the future of reefs worldwide
(11/07/2012) The Galapagos Islands have been famous for a century and a half, but even Charles Darwin thought the archipelago’s list of living wonders didn’t include coral reefs. It took until the 1970s before scientists realized the islands did in fact have coral, but in 1983, the year the first major report on Galapagos reef formation was published, they were almost obliterated by El Niño. This summer, a major coral survey found that some of the islands’ coral communities are showing promising signs of recovery. Their struggle to survive may tell us what is in store for the rest of the world, where almost three-quarters of corals are predicted to suffer long-term damage by 2030.
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.
Coral calcification rates fall 44% on Australia's Great Barrier Reef
(09/04/2012) Calcification rates by reef-building coral communities on Australia's Great Barrier Reef have slowed by nearly half over the past 40 years, a sign that the world's coral reefs are facing a grave range of threats, reports a new study published in the Journal of Geophysical Research - Biogeosciences.
Indigenous groups in Panama wait for UN REDD to meet promises
(08/30/2012) A dispute over the implementation of REDD+ (Reducing Emissions from Deforestation and Degradation) in Panama has pitted the United Nations (UN) against the nation's diverse and large indigenous groups. Represented by the National Coordinator of Indigenous Peoples in Panama (COONAPIP), indigenous groups charge that the UN has failed to meet several pledges related to kick-starting REDD+ with their support, including delaying a $1.79 million payment to the group to begin REDD+-related activities. The on-going dispute highlights the perils and complexities of implementing REDD+, especially concerns that the program might disenfranchise indigenous groups who have long been the stewards of their forest territories.
Emissions from Amazon deforestation in Brazil fall 57% since 2004
(08/29/2012) Annual emissions from deforestation in the Brazilian Amazon fell by about 57 percent between 2004 and 2011, 20 percentage points lower than the recorded drop in deforestation, reports a new study published in the journal Global Change Biology by Brazilian scientists. Overall, Brazilian deforestation represented roughly 1.5 percent of global carbon emissions from human activities.
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.
U.S. carbon emissions lowest since 1992
(08/01/2012) A shift away from coal and reduced gasoline demand coupled with a mild winter led to an 8 percent drop in U.S. carbon dioxide emissions during the first quarter of 2012, reports the Energy Information Administration. Emissions between January and March 2012 were the lowest since 1992.
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).
Experts: sustainable logging in rainforests impossible
(07/19/2012) Industrial logging in primary tropical forests that is both sustainable and profitable is impossible, argues a new study in Bioscience, which finds that the ecology of tropical hardwoods makes logging with truly sustainable practices not only impractical, but completely unprofitable. Given this, the researchers recommend industrial logging subsidies be dropped from the UN's Reducing Emissions from Deforestation and Forest Degradation (REDD+) program. The study, which adds to the growing debate about the role of logging in tropical forests, counters recent research making the case that well-managed logging in old-growth rainforests could provide a "middle way" between conservation and outright conversion of forests to monocultures or pasture.
Republican stalwart calls global warming 'a matter of fact', pushes for carbon tax
(07/13/2012) Former Secretary of State George Shultz is calling for a carbon tax to reduce U.S. greenhouse gas emissions and oil consumption, according to an interview released today by Stanford University.
Pre-industrial deforestation still warming atmosphere
(07/03/2012) Fossil fuels were not burned in massive quantities prior to the Industrial Revolution, but humans were still pumping carbon into the atmosphere due to land use change, especially deforestation. In fact, a new study in Environmental Research Letters finds that deforestation prior to 1850 is still heating up our atmosphere today.
Deforestation accounts for 10 percent of global carbon emissions, argues new study
(06/21/2012) Tropical deforestation accounted for 10 percent of global carbon dioxide emissions between 2000-2005 — a substantially smaller proportion than previously estimated — argues a new study published in Science. The paper estimates gross carbon emissions from deforestation at 810 million metric tons (with a 90 percent confidence interval of 0.57-1.22 billion tons) per year from 2000-2005, significantly below earlier calculations. Brazil and Indonesia accounted for 55 percent of gross emissions from tropical deforestation during the study period, while dry forests accounted for 40 percent of tropical forest loss but amounted to only 17 percent of emissions.
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.
Another record in global carbon emissions puts globe on track for 'devastating consequences'
(05/29/2012) Last year global carbon dioxide emissions rose 3.2 percent to a new record of 31.6 gigatons, keeping the planet on track to suffer dangerous climate change, which could propel global crop failures, sea level rise, worsening extreme weather, and mass extinction. According to data from the International Energy Agency (IEA), China's carbon emissions rose the most last year (9.3 percent) while emissions in Europe and the U.S. dipped slightly. China is the currently the world's largest emitter of greenhouse gases, while the U.S. has emitted the most historically.
Seagrass beds store 20 billion tons of carbon
(05/22/2012) Just below the ocean's surface lies a carbon powerhouse: seagrass meadows. New research in Nature Geoscience estimates that the world's seagrass meadows conservatively store 19.9 billion metric tons of carbon, even though the threatened marine ecosystems make up only 0.2 percent of Earth's surface. The findings lend support to the idea that seagrass protection and restoration could play a major role in mitigating climate change.
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.
Can loggers be conservationists?
(05/10/2012) Last year researchers took the first ever publicly-released video of an African golden cat (Profelis aurata) in a Gabon rainforest. This beautiful, but elusive, feline was filmed sitting docilely for the camera and chasing a bat. The least-known of Africa's wild cat species, the African golden cat has been difficult to study because it makes its home deep in the Congo rainforest. However, researchers didn't capture the cat on video in an untrammeled, pristine forest, but in a well-managed logging concession by Precious Woods Inc., where scientist's cameras also photographed gorillas, elephants, leopards, and duikers.
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).
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.
