Drought, fire reducing ability of Amazon rainforest to store carbon

(02/06/2014) New research published in Nature adds further evidence to the argument that drought and fire are reducing the Amazon's ability to store carbon, raising concerns that Earth's largest rainforest could tip from a carbon sink to a carbon source.


Peatland plantations drive steep GHG emissions in Indonesia's Riau Province

(02/05/2014) Versatile is the best way to describe the reddish brown fruit born from oil palm trees. Both the flesh and seed of the fruit is used in many applications including cooking, cosmetics, and biofuel. In addition, the fruit is composed of 50 percent oil, making it a highly efficient product that requires less land than other oil producing crops.


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.


Reforestation can't offset massive fossil fuels emissions

(12/13/2013) With the Australian, Japanese, and Canadian governments making an about-face on carbon-emissions reduction targets during the Warsaw climate summit, some experts are warning that the global need for solutions offsetting CO2 emissions is passing a "red line." Land-based mitigation practices comprise one of the solutions on the table as a result of both the United Nations Framework Convention on Climate Change (UFCCC) and the Kyoto Protocol; however, a paper published in Nature Climate Change by an international team led by Brendan Mackey, has raised the looming question of whether or not land-based practices can actually improve CO2 levels as much as hoped.


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.


Making cap-and-trade work: the history and future of a proven program

(12/09/2013) While the merits for slowing climate change will be treated here as a given, the method for doing so looms elusive. In a recent article, I described pricing carbon through carbon taxes and carbon credits as a way to mitigate greenhouse gas emissions and slow global climate change. As there has been some emotive controversy towards both of these, I would like to analyze them more deeply, starting here with carbon credits.


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.


Not all mangroves are created equal: new map reveals carbon storage hot-spots

(11/26/2013) Mangrove forests are one of the most important weapons in the fight against climate change. Not only do they directly store huge amounts of carbon, but they actively capture additional carbon dioxide from the atmosphere and sequester it in their soils. When mangroves are destroyed, huge quantities of carbon are released into the atmosphere, significantly contributing to greenhouse gas emissions.


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.'


Fracking: the good, the bad and the ugly

(11/18/2013) The last few years have ushered in a new national and global awareness of fracking, the 150-year-old technology for extracting natural gas and oil from rock. Fracking, short for hydraulic fracturing, uses ultra-high-pressure slurries to create hairline fractures throughout solid rock. Oil, and more frequently gas, comes rushing out while sand from the mixture holds the fractures open in this nearly alchemical process. As many readers are aware, there are two very divisive schools of thought on fracking. One side touts it as the future of energy. The other derides fracking as inherently toxic and demands its immediate and permanent cessation. Like so many aspects of life, the truth lies somewhere in between.


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.


Zoos join fossil fuel divestment movement

(11/05/2013) Last month, over a hundred representatives from zoos and aquariums around the world joined climate activism group, 350.org, pledging that their institutions would take action against global warming, including the possibility of divesting from fossil fuel companies. The effort, dubbed Zoos and Aquariums for 350, was launched during the annual meeting of the Conservation Breeding Specialist Group (CBSG).


'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.


Divestment campaign could cause considerable damage to fossil fuel industry

(10/08/2013) A campaign to persuade investors to take their money out of the fossil fuel sector is growing faster than any previous divestment campaign and could cause significant damage to coal, oil and gas companies, according to a study from the University of Oxford. The report compares the current fossil fuel divestment campaign, which has attracted 41 institutions since 2010, with those against tobacco, apartheid in South Africa, armaments, gambling and pornography. It concludes that the direct financial impact of such campaigns on share prices or the ability to raise funds is small but the reputational damage can still have major financial consequences.


Clock is ticking on fossil fuels: for first time IPCC scientists outline global carbon budget

(10/01/2013) The world's leading climate scientists have set out in detail for the first time how much more carbon dioxide humans can pour into the atmosphere without triggering dangerous levels of climate change—and concluded that more than half of that global allowance has been used up.


Global society must leave fossil fuels in the ground, unburnt, says top official

(09/26/2013) World governments must get used to the idea of leaving fossil fuel reserves in the ground unexploited and unburned, one of the world's most senior diplomats has said, ahead of a landmark report on climate science to be unveiled this Friday by the Intergovernmental Panel on Climate Change (IPCC). The former Irish president and UN high commissioner for human rights, Mary Robinson, is to spearhead a new international push aimed at breaking the climate talks deadlock and silencing skeptics, with a group of senior diplomats and politicians from around the world.


Organization proposes climate change warning labels at the gas pump

(09/05/2013) Rob Shirkey is the founder of the Toronto-based, not-for-profit organization Our Horizon. Inspired by his grandfather's last words to him, "Do what you love," Shirkey quit his job and founded the organization. Our Horizon is founded on the basis that we are all responsible for global climate change through our daily collective choices. It endeavors to influence those choices, specifically with the goal of convincing municipalities to require climate change warning labels on gasoline pumps.


Tools against climate change: carbon tax and cap-and-trade

(09/04/2013) Climate-conscious folk agree that atmospheric carbon concentration is a key greenhouse gas and a large factor in global climate change. However, there are discrepancies in the methods chosen to address the problem. Some say that carbon emissions should be banned. Some say fossil fuels should be priced. Others say that there are nuances within each. Which tools can we realistically use to mitigate climate change and the drastic effects it will have on our world?


Bad feedback: ocean acidification to worsen global warming

(08/28/2013) As if ocean acidification and climate change weren't troubling enough (both of which are caused by still-rising carbon emissions), new research published in Nature finds that ocean acidification will eventually exacerbate global warming, further raising the Earth's temperature.


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.


China pledges $275 billion over 5 years to cut record air pollution

(08/19/2013) Last week China announced it was going to spend over a quarter of a trillion dollars ($275 billion) to fight rampant and life-threatening pollution in its urban centers over the next five years. Recent decades of unparalleled economic growth has taken a drastic environmental toll in China, including record air pollution levels in Beijing. The announcement follows other news, including that the Chinese government has recently scrapped a massive 2,000 megawatt coal plant project near the cities of Hong Kong and Shenzhen.


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.


Yukon Flats experiencing more wildfires now than in the last 10,000 years

(07/22/2013) The Yukon Flats area of Alaska is today burning more frequently and severely than it has in the last 10,000 years, according to new research published in the Proceedings of the National Academy of Sciences (PNAS). Looking at charcoal fragments from 14 deep lakes in the region, scientists were able to reconstruct the fire history of this particular forest, which covers around 2,000 square kilometers. Scientists have long warned that as the temperature worldwide continue to rise from climate change, wildfires are likely to become more common.


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.


Australia terminates landmark REDD+ project in Borneo

(07/03/2013) Australia is ending its major forest restoration project in Indonesian Borneo, reports the Sydney Morning Herald.


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.


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.


Logging may destabilize carbon in forest soils

(06/14/2013) Logging in temperate zones may release more greenhouse gases than previously thought by destabilizing carbon stored in forest soils, argues a new paper published in the journal Global Change Biology-Bioenergy.


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).


Southern U.S. logging soars to meet foreign biofuel demand

(06/06/2013) In order to meet the European Union's goal of 20% renewables by 2020, some European utility companies are moving away from coal and replacing it with wood pellet fuel. The idea is simple: trees will regrow and recapture the carbon released in the burning of wood pellets, making the process supposedly carbon-neutral. But just like other simple ideas, it misses out important details that can turn it on its head.


Brazil's GHG emissions fall 39% since 2005, now 10% below 1990 levels

(06/06/2013) Brazil’s greenhouse-gas emissions dropped 39 percent between 2005 and 2010, largely due to a reduction in deforestation, reports an inventory released yesterday by the Brazilian government.


Higher CO2 levels cause 'greening' from fertilization effect

(05/31/2013) Rising atmospheric carbon dioxide levels has triggered 'greening' in arid regions around the world due to a fertilization effect that has increased plant growth, reports a new study published in Geophysical Research Letters.


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.


Indonesia's largest coal plant will be built despite protests, minister says

(05/26/2013) Indonesia will go ahead with construction of what is set to be its largest coal-fired power plant in Batang, Central Java next year, a senior government official has said, downplaying opposition from environmental groups and the local community. Developers have struggled to acquire the approximately 200 hectares of land needed for the planned PLTU Batang plant, which would have a 2000 megawatt (MW) capacity. Residents of five villages have protested the project, with some refusing to release their land on fears of potential environmental damage to the area. Environmental groups also oppose the plant, saying it overlaps with a marine protected area and runs counter to President Susilo Bambang Yudhoyono’s commitment to reduce carbon emissions.


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.


Canadian government drops over $16 million on advertising its tar sands

(05/16/2013) The Canadian government has nearly doubled its advertising spending to promote the Alberta tar sands in an aggressive new lobbying push ahead of Thursday's visit to New York by the prime minister, Stephen Harper. The Harper government has increased its advertising spending on the Alberta tar sands to $16.5m from $9m a year ago.


Last time CO2 hit 400 ppm, temperature was 8C warmer, seas 40m higher than today

(05/12/2013) The future of a globally warmed world has been revealed in a remote meteorite crater in Siberia, where lake sediments recorded the strikingly balmy climate of the Arctic during the last period when greenhouse gas levels were as high as today.


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.


Brazil's satellite monitoring reduced Amazon deforestation by 60,000 sq km in 5 years

(05/08/2013) Brazil's advanced satellite monitoring system, coupled with increased law enforcement, was responsible for nearly 60 percent of the 101,000 square kilometer-drop in deforestation observed between 2007 and 2011, argues a new study published an international think tank.
