(02/27/2014) Methane leaks from palm oil wastewater significantly increases the climate impact of palm oil production beyond emissions from land clearance, fire, and peatlands drainage, reports a new study published in Nature Climate Change. The research, led by Philip. G. Taylor of the University of Colorado, finds that annual methane emissions from palm oil wastewater effluent amount to the equivalent of 115 million tons carbon dioxide in Malaysia and Indonesia alone, or roughly 15 percent of total emissions from peat oxidation and land use change in the two countries.
Carbon emissions rise 2 percent in U.S. due to increase in coal
(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 10 HAPPY environmental stories of 2013
(12/19/2013) China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.
Top 10 Environmental Stories of 2013
(12/10/2013) 1. Carbon concentrations hit 400ppm while the IPCC sets global carbon budget: For the first time since our appearance on Earth, carbon concentrations in the atmosphere hit 400 parts per million. The last time concentrations were this high for a sustained period was 4-5 million years ago when temperatures were 10 degrees Celsius higher. Meanwhile, in the slow-moving effort to curb carbon emissions, the Intergovernmental Panel on Climate Change (IPCC) crafted a global carbon budget showing that most of the world's fossil fuel reserves must be left untouched if we are to avoid catastrophic climate change.
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.
Mining the Heart of Borneo: coal production in Indonesia
(11/20/2013) Indonesia is the world’s top exporter of coal – supplying energy to China, India, and elsewhere. Indonesia is also ranked the fourth top emitter of greenhouse gases in the world (after China, the USA, and the European Union), largely due to high deforestation rates and peatland fires. This ranking does not take into consideration the carbon emissions that Indonesia ‘exports’ in the form of coal.
UN talks tough to global coal industry
(11/19/2013) Yesterday, at the International Coal and Climate Summit—just a couple miles from the ongoing UN Climate Summit—Christiana Figueres delivered a speech unlike anything ever heard at a coal industry meeting before. Figueres, the Executive Director of the UN Framework Convention on Climate Change (UNFCCC), took time off from wrangling world leaders and officials toward a climate agreement to talk tough to an industry currently worth around $3 trillion.
Carbon emissions set to hit new record high in 2013
(11/19/2013) The amount of carbon dioxide emitted into the atmosphere in 2013 is expected to hit a new high of 36 billion tonnes, according to a Carbon Budget released today by the Global Carbon Project (GCP). This is a 2.1 percent rise from 2012 based on data from the same group. 'We have exhausted about 70 per cent of the cumulative emissions that keep global climate change likely below two degrees,' said GCP member, Pierre Friedlingstein, with the University of Exeter. 'In terms of CO2 emissions, we are following the highest climate change scenario of the Intergovernmental Panel on Climate Change released in September.'
60,000 protest in Australia to keep carbon price
(11/18/2013) Around 60,000 Australians marched yesterday across the country calling on their government not to go backwards on climate action, according to organizers. Australia has taken a sudden U-turn on climate policy with the election of Prime Minister Tony Abbott in September, including legislation to end its carbon pricing, cutting funding to renewable energies, and obstructing progress at the ongoing UN Climate Summit in Warsaw.
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.
World's most vulnerable nation to climate change turns to coal power
(11/18/2013) In October, a global risks analysis company, Maplecroft, named Bangladesh the world's most vulnerable nation to climate change by 2050. The designation came as little surprise, since Bangladesh's government and experts have been warning for years of climatic impacts, including rising sea levels, extreme weather, and millions of refugees. However, despite these very public warnings, in recent years the same government has made a sudden turn toward coal power—the most carbon intensive fuel source—with a master plan of installing 15,000 megawatts (MW) of coal energy by 2030, which could potentially increase the country's current carbon dioxide emissions by 160 percent.
Coal's future carbon costs may make it more expensive than wind energy
(11/15/2013) At first glance, a recent report from the U.S. White House on the social cost of carbon reads like a daunting economics exam. A small chart poses the first question about the price tag policymakers attach to future greenhouse gas emissions: Does each metric ton of carbon that billows into the air cost $11, $33 or $52? The answer is all of the above.
Is Australia becoming the new Canada in terms of climate inaction?
(11/14/2013) For many concerned about climate change, Australia has suddenly become the new Canada. With the election of Tony Abbott as Prime Minister in September, the land down under has taken a sudden U-turn on climate policy, including pushing to end its fledgling carbon emissions program which was only implemented in 2012 and cutting funding for renewable energy. These move come at a time when Australia has just undergone its warmest 12 months on record and suffered from record bushfires.
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.
'Remarkable year': could 2012 mark the beginning of a carbon emissions slowdown?
(10/31/2013) Global carbon dioxide emissions hit another new record of 34.5 billion tons last year, according to a new report by the Netherlands Environment Assessment Agency and the European Commission's Joint Research Centre, but there may be a silver lining. Dubbing 2012 a "remarkable year," the report found that the rate of carbon emission's rise slowed considerably even as economic growth continued upward.
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.
Featured video: temperature rises across North America by 2100
(08/19/2013) A new short video predicts temperature changes across North America depending on the future of greenhouse gas emissions. Produced by NASA, the first series shows average temperatures changes (relative to 1970-1999) based on carbon dioxide levels hitting 550 parts per million (ppm) in the atmosphere by 2100. The second, even more dramatic series, shows changes if levels hit 800 ppm by the end of the century. Earlier this year, carbon dioxide levels hit 400 ppm for the first time in around 5 million years, which is longer than humans have been around.
Forests may be using less water as CO2 rises
(07/11/2013) Forests may be becoming more efficient in their use of water as atmospheric carbon dioxide levels rise, reports a new study in Nature.
Rising temperatures are triggering rainforest trees to produce more flowers
(07/09/2013) Slight rises in temperatures are triggering rainforest trees to produce more flowers, reports a new study published in the journal Nature Climate Change.
Conserving top predators results in less CO2 in the air
(06/19/2013) What does a wolf in Yellowstone National Park have in common with an ambush spider on a meadow in Connecticut? Both are predators and thus eat herbivores, such as elk (in the case of wolves) and grasshoppers (in the case of spiders). Elk and grasshoppers also have more in common than you probably imagine: they both consume large quantities of plant matter. While scientists have long-known that predators lead to carbon storage by reducing herbivore populations, a new study reveals a novel way in which top predators cause an ecosystem to store more carbon.
CO2 emissions hit record in 2012
(06/10/2013) Carbon dioxide emissions from fossil fuels use hit a record in 2012, according to a new report from the International Energy Agency (IEA).
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.
Mystery of Amazon River carbon emissions solved
(05/21/2013) Bacteria living in the Amazon River digest nearly all wood plant matter that enters the river before it reaches the Atlantic Ocean, triggering the release of carbon locked up in the vegetation instead of sequestering it in the deep ocean, finds a new study published in Nature Geoscience. The research explains the mechanism by which the world's largest river 'exhales' large amounts of CO2.
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.
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.
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.
