(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.
Microhabitats could buffer some rainforest animals against climate change
(11/25/2013) As temperatures increase worldwide due to anthropogenic climate change, scientists are scrambling to figure out if species will be able to survive rapidly warming ecosystems. A new study in Global Change Biology offers a little hope. Studying reptiles and amphibians in the Philippines, scientists say some of these species may be able to seek refuge in cooler microhabitats, such as tree holes or under the soil, in order to stay alive during intensifying heatwaves. But, the scientists' stress, the shelter from microhabitats can only protect so far.
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.
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.
Philippines' delegate calls out climate change deniers after Haiyan
(11/12/2013) Yesterday, the Filipino delegate to the ongoing climate summit, Naderev 'Yeb' Saño, dared climate change deniers to take a hard look at what's happening not just in the Philippines, but the whole world. Over the weekend, the Philippines was hit by what may have been the largest typhoon to ever make landfall—Typhoon Haiyan. Reports are still coming in days later, but the death toll may rise to over 10,000 with whole cities simply swept away.
Delegate for the Philippines vows to stop eating at climate summit
(11/11/2013) Following the devastation wrought by Typhoon Haiyan—which is arguably the strongest typhoon to ever make landfall—Filipino delegate, Naderev 'Yeb' Saño, has vowed to go on a fast at the UN Climate Summit that opened today in Warsaw, Poland. Saño made the vow during a powerful speech in which he said he would fast, 'until we stop this madness.'
Bangladesh plans massive coal plant in world's biggest mangrove forest
(11/11/2013) On October 22nd Bangladeshi and Indian officials were supposed to hold a ceremony laying the foundation stone for the Rampal power plant, a massive new coal-fired plant that will sit on the edge of the Sundarbans, the world's largest mangrove forest. However, the governments suddenly cancelled the ceremony, instead announcing that the project had already been inaugurated in early October by the countries' heads of state via a less-ornate Skype call. While the governments say the change was made because of busy schedules, activists contend the sudden scuttling of the ceremony was more likely due to rising pressure against the coal plant, including a five-day march in September that attracted thousands.
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.
Renewable energy revolution will require better management of metals
(10/30/2013) If we are to avoid catastrophic climate change, scientists say global society will need a rapid and aggressive replacement of fossil fuel energy for renewable, such as solar, wind, geo-thermal, and tidal. While experts say a renewable revolution would not only mitigate climate change but also likely invigorate economies and cut life-threatening pollution, such a revolution would not come without challenges. According to a new commentary piece in Nature Geoscience one of the largest challenges of the renewable revolution will be rising demand for metals, both rare and common.
America's growing inequality helped scuttle the global climate change initiative
(10/28/2013) The link between good economic policy and climate change mitigation is instigated by policies such as the triple-bottom line, carbon limitations, and pro-environmental legislation. However, economic inequality is a little explored piece of the successful fight against climate change. For climate change mitigation and good economic policy to work, economic growth must be broad-based. Indeed, the inability for the United States to make a coherent and progressive stance on climate change has effectively stymied the global initiative—and is in part due to growing inequality. Due to the nation's market size and political power, U.S. policy is often a decisive factor for many global issues.
Global warming could shift tropical rainfall
(10/21/2013) Ongoing burning of fossil fuels could flip which portion of the tropics receive more rainfall: the southern hemisphere or the northern. Currently, the northern hemisphere tropics is the wetter of the two, but why this is has long baffled scientists. Now, new research in Nature Geoscience has discovered that rainfall in the tropics is in part driven by massive ocean currents that travel back-and-forth between the Arctic and Antarctic, a process known as ocean overturning circulation.
WHO: air pollution causes cancer
(10/17/2013) Outdoor air pollution has been officially classified as carcinogenic by the cancer arm of the World Health Organization. The International Agency for Research on Cancer (IARC) said air pollution from traffic and industrial fumes was a definite cause of lung cancer and also linked to bladder cancer. The strong verdict from IARC, a cautious body that pronounces only when the evidence is strong, will put pressure on governments to take action.
David Attenborough: someone who believes in infinite growth is 'either a madman or an economist'
(10/16/2013) Sir David Attenborough has said that people living in poorer countries are just as concerned about the environment as those in the developed world, and "exporting environmentalism" isn't necessarily an "uphill struggle". The veteran broadcaster said ideas about protecting the natural world were not unwelcome in less developed nations—but added that wealthier countries should work to improve women's rights around the world to bring down birth rates and avoid overpopulation.
Governments should respond to ocean acidification 'as urgently as they do to national security threats'
(10/03/2013) The oceans are more acidic now than they have been for at least 300m years, due to carbon dioxide emissions from burning fossil fuels, and a mass extinction of key species may already be almost inevitable as a result, leading marine scientists warned on Thursday. An international audit of the health of the oceans has found that overfishing and pollution are also contributing to the crisis, in a deadly combination of destructive forces that are imperiling marine life, on which billions of people depend for their nutrition and livelihood.
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.
'Yet another wakeup call': global warming is here, it's manmade, and we're not doing enough to stop it
(09/28/2013) Human actions are responsible for warming the Earth, reconfirms the landmark Intergovernmental Panel on Climate Change (IPCC) report released today, the first mammoth report on the physical science of climate change issued in seven years. Scientists now say they are 95-100 percent certain that human actions—such as burning fossil fuels and cutting down forests—are behind the observed rise in global temperatures since at least 1950. Average temperatures have risen 0.85 degrees Celsius since 1880, but the new report warns that depending on how much more fossil fuels are burnt, temperature rises could exceed 4 degrees Celsius (9 degrees Fahrenheit) with untold consequences for global society.
Which ecosystems are most vulnerable to climate change?
(09/16/2013) New research highlights the world's most (and least) vulnerable ecosystems to climate change. The study, published in Nature Climate Change, is the first to combine anticipated climatic impacts with how degraded the ecosystem is due to human impacts, creating what scientists hope is a more accurate list of vulnerable regions. The most endangered regions include southern and southeast Asia, western and central Europe, eastern South America, and southern Australia.
Butchering nature's titans: without the elephant 'we lose an essential pillar in the ability to wonder'
(09/12/2013) Africa's elephant poaching crisis doesn't just threaten a species, but imperils one of humanity's most important links to the natural world and even our collective sanity, according to acclaimed photographers and film-makers, Cyril Christo and Marie Wilkinson. Authors of the book Walking Thunder - In the Footsteps of the African Elephant, Christo and Wilkinson have been documenting Africa's titans in photos and film for several years. In 2011, the pair released a film Lysander's Song (named after their son an avid fan of elephants) which depicts the millennial-old relationship between humans and elephants.
U.S. to crush its six ton ivory stockpile
(09/10/2013) On October 8th, the Obama administration will publicly destroy its ivory stockpile, totaling some six tons, according to a White House forum yesterday on the illegal wildlife trade. The destruction of the stockpile—via crushing—is meant to send a message that the U.S. is taking a tougher stand on illegal the wildlife trade, which is decimating elephants across Africa and imperiling other animals worldwide. The U.S. remains one of the biggest destinations for ivory and other illegal animal part aside from East Asia.
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?
Featured video: how tigers could save human civilization
(08/29/2013) In the video below, John Vaillant, author of the The Tiger: A True Story of Vengeance and Survival, tells an audience at TEDxYYC about the similarities between tigers and human beings. Given these similarities—big mammals, apex predator, highly adaptable, intelligent, and stunningly 'superior'—John Vaillant asks an illuminating question: what can we learn from the tiger? It turns out learning from tigers could help conserve the human race.
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.
Humanity consumes this year's resources 133 days too early
(08/20/2013) Today is Earth Overshoot Day, according to the Global Footprint Network and WWF's Living Planet Report, which means the seven billion people on Earth have consumed the globe's renewable resources for the year. In other words for the next 133 days humanity will be accumulating ecological debt by overdrawing on our collective resources.
In defense of the financial industry: stocking up to end climate change
(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.
Novel Ecosystems: Intervening in the New Ecological World Order - book review
(08/12/2013) Novel Ecosystems: Intervening in the New Ecological World Order is a recent textbook published by Wiley-Blackwell edited by Richard J. Hobbs, Eric S. Higgs, and Carol M. Hall that describes the emerging issues around novel ecosystems. Novel ecosystems are rapidly developing globally in response to land conversion, climate change, invasive species, and other ecological crises. Novel ecosystems are anthropogenically modified ecosystems that have developed during the Anthropocene.
Foodies eat lab-grown burger that could change the world
(08/06/2013) Yesterday at a press event in London, two food writers took a bite into the world's most unusual hamburger. Grown meticulously from cow stem cells, the hamburger patty represents the dream (or pipedream) of many animal rights activists and environmentalists. The burger was developed by Physiologist Mark Post of Maastricht University and funded by Google co-founder Sergey Brin in an effort to create real meat without the corresponding environmental toll.
Climate could warm more rapidly than any time in the last 65 million years
(08/01/2013) According to a new review of 27 climate models, scientists say the global climate is likely to experience a warmth as great as any in the last 65 million years, only much, much faster. According to the study published today in Science, the Earth's land temperature will rise by 4 degrees Celsius (7.2 degrees Fahrenheit) from pre-industrial levels by 2100 if we continue on our current emissions trajectory.
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.
Arctic melt to cost trillions
(07/30/2013) Rapid thawing of the Arctic could trigger a catastrophic "economic timebomb" which would cost trillions of dollars and undermine the global financial system, say a group of economists and polar scientists. Governments and industry have expected the widespread warming of the Arctic region in the past 20 years to be an economic boon, allowing the exploitation of new gas and oilfields and enabling shipping to travel faster between Europe and Asia.
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.
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.
Fertility in Africa could push world population over 11 billion
(06/13/2013) The global population could grow by another 4 billion people by the end of the century if fertility rates in Africa don't decline, according to a new report by the United Nations. Currently around 1.1 billion people live on the continent, but that number could skyrocket to 4.2 billion (a 380 percent increase) by 2100, causing global population to hit 11 billion.
Ocean acidification pushing young oysters into 'death race'
(06/11/2013) Scientists have long known that ocean acidification is leading to a decline in Pacific oyster (Crassostrea gigas) in the U.S.'s Pacific Northwest region, but a new study in the American Geophysical Union shows exactly how the change is undercutting populations of these economically-important molluscs. Caused by carbon dioxide emissions, ocean acidification changes the very chemistry of marine waters by lowering pH levels; this has a number consequences including decreasing the availability of calcium carbonate, which oysters and other molluscs use to build shells.
Earth likely to warm between 2 and 6 degrees Celsius this century
(05/30/2013) A new study by Australian scientists projects that the world will likely warm between 2 and 6 degrees Celsius (3.6 to 10.8 degrees Fahrenheit) from pre-industrial levels by 2100. The study published in Nature Climate Change finds that exceeding the 2-degree threshold is very likely under business-as-usual emissions scenarios even as scientists have long warned that passing the 2-degree mark would lead to catastrophic climate change.
Water crisis widening: 4.5 billion people live near 'impaired water sources'
(05/28/2013) The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned.
Over 500 scientists warn we 'are causing alarming levels of harm to our planet'
(05/27/2013) A new consensus statement by 520 scientists from around the world warns that global environmental harm is putting at risk the happiness and well-being of this and future generations.
Prince Charles: take the war to the poachers
(05/22/2013) Prince Charles has warned that criminal gangs are turning to animal poaching, an unprecedented slaughter of species that can only be stopped by waging war on the perpetrators, in the latest of a series of increasingly outspoken speeches about the environment. Addressing a conference of conservationists at St James's Palace in London, the Prince of Wales announced a meeting of heads of state to take place this autumn in London under government auspices to combat what he described as an emerging, militarized crisis.
Biosphere conservation: monumental action is critical to avert global environmental crisis
(05/20/2013) Human-caused changes to our biosphere—the global total of the world's ecosystems—are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded. We may survive, we may painfully adapt, but it is a fair bet that grave hardship, loss, and sacrifice lay ahead. The nature and extent of impacts among human populations hinges on how successfully we respond to the biosphere crisis with extraordinary leadership, balanced solutions applied at global scales, and unprecedented cooperation—or not.
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.
Featured video: How climate change is messing with the jetstream
(05/08/2013) Weather patterns around the globe are getting weirder and weirder: heat waves and record snow storms in Spring, blasts of Arctic air followed by sudden summer, record deluges and then drought.
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.
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.
Top security official in Nigeria blames climate change for worsening insecurity
(04/25/2013) Climate change is in part to blame for rising conflict and crime in Nigeria, according to the president's National Security Advisor, Colonel Sambo Dasuki. Speaking to the House Committee on Climate Change, Dasuki said that the rise of Boko Haram insurgents, a jihadist group in northern Nigeria, and worsening crime was linked to climate change reports All Africa.
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.
