Could big data turn us into ocean protectors instead of abusers?
(02/24/2015) The devastating tsunami that hit Japan in 2011 washed away millions of tons of plastic debris into the Pacific Ocean. It even swept away a Harley Davidson motorcycle that subsequently ended up on Canada's coast. As production and consumption of plastic increases across the world, more of it gets discarded as waste.
U.S. Central Plains and Southwest will likely face apocalyptic drought
(02/12/2015) In the recent film Interstellar, a mysterious phenomenon known as "the blight" is wiping out agriculture around the world until only corn—for some reason—survives. Humanity is on the brink of starvation. While the blight may be science fiction, global warming is not, and a new study finds that future warming could decimate the western U.S. over the next century.
Pollution from fossil fuels decreased rainfall in Central America
(02/10/2015) Fossil fuel pollution may have caused a southern shift in a vital rainfall belt across Central America, according to a new study in Nature Geoscience, potentially leading to drier conditions and droughts in some northern tropical countries. Using data from a single stalagmite in a Belizean cave, the researchers were able to create an accurate record of both rainfall and temperature for the last 450 years.
Norway sovereign fund drops coal, tar sands, gold-mining companies
(02/09/2015) In its first-ever report on responsible investing, Norway's pension fund announced last week that it has divested from 114 companies in the past three years due to concerns over global warming, deforestation, and sustainability as well as long-term financial viability. Worth a staggering $861 billion, Norway's Government Pension Fund Global (GPFG) is the world's largest sovereign wealth fund.
The Amazon's oil boom: concessions cover a Chile-sized bloc of rainforest
(02/04/2015) Hungry for oil revenue, governments and fossil fuel companies are moving even further into one of the world's last great wildernesses, according to a new study in the journal Environmental Research Letters. The total area set aside for oil and gas in the Western Amazon has grown by 150,000 square kilometers since 2008, now totaling more than 730,000 square kilometers—an area the size of Chile.
Even with no El Nino, 2014 was the warmest year on record
(01/18/2015) On Friday both NASA and NOAA announced that last year—2014—was the warmest on record. The year bested out both previous record holders, 2005 and 2010. According to NOAA, 2014 was 0.69 degrees Celsius (1.24 degrees Fahrenheit) above the 20th century average. The Earth is warming rapidly due to greenhouse gas emissions, mostly from burning fossil fuels such as coal, oil, and gas.
Ocean's 15: meet the species that have vanished forever from our seas
(01/15/2015) In the last 500 years, the oceans have suffered far fewer extinctions than on land—at least that we know of. According to a recent study in Science, 15 animals are known to have vanished forever from the oceans while terrestrial ecosystems have seen 514 extinctions. The researchers, however, warn that the number of marine extinctions could rise rapidly as the oceans are industrialized.
Empty seas? Scientists warn of an industrialized ocean
(01/15/2015) This is obvious, but still important: humans are not a marine species. Even as we have colonized most of our planet's terrestrial landscapes, we have not yet colonized the oceans. And for most of our history, we have impacted them only on the periphery. A new review in Science finds that this has saved marine species and ecosystems from large-scale damage—that is, until the last couple centuries.
Video: global carbon dispersal looks like an impressionistic painting in motion
(01/12/2015) A new video showing the global movements of carbon dioxide during one year may look beautiful, but such impressions are misleading. The video, produced by NASA, shows just how much humans are impacting the world's atmosphere, leading to rising temperatures, ocean acidification, melting glaciers, vanishing sea ice, and untold impacts on both wildlife and human communities.
Top 10 Environmental Stories of 2014
(12/23/2014) In 2014, the unimaginable happened: companies representing the majority of palm oil production and trade agreed to stop cutting down rainforests and draining peatlands for new oil palm plantations. After years of intense campaigning by environmentalists and dire warnings from scientists, nearly two dozen major producers, traders, and buyers established zero deforestation policies.
Edited Reality: What I Learned from Filming Eaten Alive
(12/22/2014) On November 3, 2014, I woke up to check my flight status from Bangalore to New York. What I found when I opened my laptop was a mindboggling amount of emails, hate mail, death threats, and interview requests. The numbers were staggering. The night before, the Discovery Channel had aired the first trailers for the show they decided to call Eaten Alive.
A tale of 2 Perus: Climate Summit host, 57 murdered environmentalists
(11/18/2014) On September 1st, indigenous activist, Edwin Chota, and three other indigenous leaders were gunned down and their bodies thrown into rivers. Chota, an internationally-known leader of the Asháninka in Peru, had warned several times that his life was on the line for his vocal stance against the destruction of his peoples' forests, yet the Peruvian government did nothing to protect him—or others.
Is the world moving backwards on protected areas?
(11/06/2014) Protected areas are undoubtedly the world's most important conservation success story. But, despite this, progress on protected areas is stalling and in some cases even falling behind. According to a sobering new paper, only 20-50 percent of the world's land and marine protected areas are meeting their goals, while the rest are hampered by lack of funding, poor management, and government ambivalence.
Can we stop runaway global warming? 'All we need is the will to change'
(11/03/2014) Twenty-six years after the founding of the IPCC, the Nobel Prize-winning group of scientists has released a new synthesis report that warns in its strongest tones yet that climate change must be dealt with. None of the findings are surprising—they have been released in earlier assessments throughout the year—but the terms in which they are written are the starkest yet.
The only solution for polar bears: 'stop the rise in CO2 and other greenhouse gases'
(10/08/2014) Steven Amstrup, Chief Scientist for Polar Bears International, has worked diligently on polar bears for over 30 years. He radio-collared some of the first bears and discovered that annual activity areas for 75 tracked females averaged at a stunning 149,000 square kilometers. His recent work highlighted the cost of global warming to these incredible animals and the sea ice they so closely depend on.
Leonard DiCaprio to UN Climate Summit: 'You can make history or you will be vilified by it'
(09/23/2014) Actor, environmental activist, and recently named UN Messenger of Peace, Leonardo DiCaprio, spoke today to a UN Climate Summit. The summit, which is hosting the largest gathering of world leaders to address the crisis in five years, is meant to pave the way for a new climate agreement in Paris in 2015.
Climate coup: Rockefeller announces they are dropping fossil fuel investments
(09/22/2014) In 1870, John D. Rockefeller founded the Standard Oil Company. Rapidly becoming the world's largest oil refiner, Standard made Rockefeller a billionaire and one of the world's greatest philanthropists. 144 years later and John D. Rockefeller's descendants have announced they are stripping fossil fuels from the Rockefeller Brothers Fund, a private charity with around $860 million in assets.
Chinese now emit more carbon per capita than Europeans
(09/22/2014) Last year, the people of China emitted more carbon per person than those in the EU, according this year's Global Carbon Budget. The report, updated annually, also found that global emissions jumped 2.5 percent last year and are set to hit a record high of 40 billion tonnes this year. The findings highlight how little global society has done to stem emissions, despite numerous pledges and past global agreements.
World population could surpass 13 BILLION by the end of the century
(09/18/2014) By 2100, over 13 billion people could be walking the planet. That's the conclusion of a new study published today in Science, which employed UN data to explore the probability of various population scenarios. The new study further demolishes the long-held theory that human population growth will quit growing by mid-century and then fall.
Next big idea in forest conservation? Harness the power of marketing
(09/11/2014) As a whole, conservationists have been slow to adapt the strategies of marketing or to market conservation at all. Dr. Diogo Veríssimo, a researcher who works at the interface between social and natural sciences, with a focus on behavior change and evidence-based conservation, thinks this needs to change.
'We are running out of time': CO2 concentrations in the atmosphere surprise scientists
(09/10/2014) The concentration of carbon dioxide in the atmosphere made the biggest jump last year since 1984, according to the World Meteorological Organization's (WMO) Greenhouse Gas Bulletin, raising alarm bells about society's inaction on curbing global warming.
Why conservationists need a little hope: saving themselves from becoming the most depressing scientists on the planet
(08/19/2014) Here's a challenge: take a conservationist out for a drink and ask them about their work. Nine times out of ten—or possibly more—you'll walk away feeling frustrated, despondent, and utterly hopeless. Yet a few conservation scientist are not just trying to save species from extinction, but also working to save their field—their life's work—from slipping into total despair.
13 newly-discovered birds declared extinct
(08/18/2014) In a recent update of the IUCN Red List, scientists have identified 13 new bird species that have gone extinct since 1500. In total the list now finds that at least 140 bird species gone extinct in the past five hundred years, representing 1.3 percent of the world's total known birds.
Indonesia's children see ravaged environment in their future
(08/11/2014) A generation ago, Borneo was one of the wildest places on the planet. But decades of logging and oil palm plantations has changed the landscape of Borneo forever: in fact a recent study found that the island has lost 30 percent of its total forest cover since 1973. In the face of this large-scale environmental destruction, a new study finds that Indonesian Borneo's children have a pessimistic view of their future.
Biomass burning accounts for 18% of CO2 emissions, kills a quarter of a million people annually
(08/05/2014) Biomass burning takes many forms: wildfires, slash-and-burn agriculture, clearing forests and other vegetation, and even industrialized burning for energy production. Yet this burning—mostly manmade but also natural—takes a massive toll both on human health and the environment.
It's not just extinction: meet defaunation
(07/24/2014) Get ready to learn a new word: defaunation. Fauna is the total collection of animals—both in terms of species diversity and abundance—in a given area. So, defaunation, much like deforestation, means the loss of animals in all its myriad forms, including extinction, extirpation, or population declines.
Peru slashes environmental protections to attract more mining and fossil fuel investment
(07/23/2014) In an effort to kickstart investment in mining and fossil fuels, Peru has passed a controversial law that overturns many of its environmental protections and essentially defangs its Ministry of Environment. The new law has environmentalists not only concerned about its impact on the country but also that the measures will undermine progress at the up-coming UN Climate Summit in December.
'Stop using the bloody things': pesticides linked to bee collapse now blamed for bird declines
(07/15/2014) In recent years the evidence has piled up that neonicotinoids—a hugely popular group of pesticide—may be at least partly responsible for ongoing bee and pollinator collapse. But new research in the journal Nature find that these pesticides could also be taking a heavy toll on other species, in this case common birds.
Only 15 percent of world's biodiversity hotspots left intact
(07/14/2014) The world's 35 biodiversity hotspots—which harbor 75 percent of the planet's endangered land vertebrates—are in more trouble than expected, according to a sobering new analysis of remaining primary vegetation. In all less than 15 percent of natural intact vegetation is left in the these hotspots, which include well-known jewels such as Madagascar, the tropical Andes, and Sundaland.
A garden or a wilderness? One-fifth of the Amazon may have been savannah before the arrival of Europeans
(07/09/2014) The Amazon is the largest tropical forest on the planet, covering about 6.5 million square kilometers, although much has been lost in recent decades.Yet new research published in the Proceedings of the National Academy of Sciences (PNAS) finds that quite recently—just 500 years ago—a significant portion of the southern Amazon was not the tall-canopied forest it is today, but savannah.
Unrelenting population growth driving global warming, mass extinction
(06/26/2014) It took humans around 200,000 years to reach a global population of one billion. But, in two hundred years we've septupled that. In fact, over the last 40 years we've added an extra billion approximately every dozen years. And the United Nations predicts we'll add another four billion—for a total of 11 billion—by century's end.
April 2014: 350th month in a row with temperatures above average
(06/04/2014) This April was notable for being the 350th month in a row where temperatures exceeded the 20th Century average. This means, monthly global temperatures have not fallen below average for even a single month since February 1985.
Turning point? U.S. and China announce major actions on global warming
(06/03/2014) Could 2014 be a turning point for efforts to slash global greenhouse gas emissions? Maybe: in less than 24 hours the world's two largest emitters of carbon dioxide announced plans to finally rein-in the gas most responsible for global warming.
Extinction rates are 1,000x the background rate, but it's not all gloomy
(05/29/2014) Current extinction rates are at the high end of past predictions, according to a new paper published today in Science, however conservation efforts combined with new technologies could make a big difference. New research led by Stuart Pimm of Duke University argues that humans have pushed the current extinction rate to 1,000 times the historical rate.
Climate change's ominous secret
(05/21/2014) Climate change is happening and humans are causing it, primarily from the increase in atmospheric carbon dioxide caused by burning fossil fuels. This much we know. The 'secret' comes from changes happening in the fast-warming Arctic: we may be surprisingly close to an Earth that supports far fewer humans than it does today.
Tipping point already reached? West Antarctica in slow-motion, unstoppable melt
(05/14/2014) Two hundred years from now, the planet could look very different. This week two landmark studies revealed that West Antarctica's ice sheet is in a state of seemingly inevitable collapse linked to climate change. The slow-motion collapse would by itself eventually lead to a rise in global levels of 3.6-4.5 meters (12-15 feet).
Stanford kicks coal out of its $18 billion endowment
(05/07/2014) The fossil fuel divestment campaign won a major victory today as Stanford University announced it would drop coal companies from its massive $18.7 billion endowment, the fourth largest of any American university. The action follows a petition by student group Fossil Free Stanford and five months of research by Stanford's Advisory Panel on Investment Responsibility and Licensing.
Next big idea in forest conservation? Maps for the masses
(04/18/2014) Mark Mulligan makes maps for the masses. In his work on tropical forests, Mulligan uses GIS, modeling, remote sensing, and lab experiments to turn research into datasets and policy support systems, which are available online for use in development, decision-making, and education.
Climate change solution? UN touts ambitious (but cheap) investment in renewable energy
(04/14/2014) The world is warming rapidly due to greenhouse gas emissions, threatening everything from our food supply to our ecosystems, but the solution may be surprisingly cheap, according to the third and final report from the Intergovernmental Panel on Climate Change (IPCC). The report recommends a rapid and aggressive switch from fossil fuel-based energy to renewables.
Next big idea in forest conservation? Empowering everyone to watch over forests
(04/10/2014) Nigel Sizer has worked on the forefront of global forest issues for decades. Currently, he is the Global Director of the World Resource Institute's (WRI) Forests Program, whose projects include the Global Forest Watch, the Forest Legality Alliance, and the Global Restoration Initiative. These programs work with governments, businesses, and civil society with the aim of sustaining forests for generations to come.
Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
(03/31/2014) It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report states definitively that climate change is already affecting human societies on every continent.
Two kids, one year, from the Amazon to the Arctic: the environmental adventure of a lifetime
(02/19/2014) The Kraft family—Larry, Lauri, Jamie (age 8), and Jason (age 6)—are on the trip of a lifetime, a round-the-world tour with an environmental focus. Currently in India, the family has already made their way through the Amazon, Vietnam, Costa Rica, Australia, and the Galapagos, among other wild places. Still left on their itinerary: the Arctic. But the trip isn't all fun and games, instead the Kraft's are using the year abroad to learn first hand about global environmental issues and solutions.
Predator appreciation: how saving lions, tigers, and polar bears could rescue ourselves
(01/29/2014) In the new book, In Predatory Light: Lions and Tigers and Polar Bears, authors Elizabeth Marshall Thomas, Sy Montgomery, and John Houston, and photographers Cyril Christo and Marie Wilkinson share with us an impassioned and detailed appeal to appreciate three of the world's biggest predators: lions, tigers, and polar bears. Through lengthy discussions, combining themes from scientific conservation to local community folklore, In Predatory Light takes us step by step deeper into the wild world of these awe-inspiring carnivores and their varied plight as they facedown extinction.
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.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Down Under scorching: Australia experiences warmest year on record
(01/06/2014) Australia had its warmest year on record, with annual temperatures 1.2 degrees Celsius (2.16 degrees Fahrenheit) above the 1961-1990 average, according to a new analysis from Australia's Bureau of Meteorology (BOM). This is 0.5 degrees Celsius higher than the previous warmest year on record—2005—for Australia. Global warming due to burning fossil fuels is increasing temperatures worldwide.
Global warming could upset Antarctic food chain
(01/02/2014) Resting near the bottom of the foodchain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarctic krill could lose 20 percent of their growth habitat, or 1.2 million square kilometers.
World first: Russia begins pumping oil from Arctic seabed
(12/23/2013) Oil has begun to be pumped from the Arctic seabed, according to Russian oil giant, Gazprom. The company announced on Friday that it has begun exploiting oil reserves at the offshore field of Prirazlomnoye. The project, which is several years behind schedule, is hugely controversial and made international headlines in September after Russian military arrested 28 Greenpeace activists protesting the operation along with a British journalist and Russian videographer.
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.
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.
Last 30 years were the warmest in the last 1,400 years
(04/21/2013) From 1971 to 2000, the world's land areas were the warmest they have been in at least 1,400 years, according to a new study in Nature Geoscience. The massive new study, involving 80 researchers from around the world with the Past Global Changes (PAGES) group, is the first to look at continental temperature changes over two thousand years, providing insights into regional climatic changes from the Roman Empire to the modern day. According to the data, Earth's land masses were generally cooling until anthropogenic climate change reversed the long-term pattern in the late-19th Century.
Scientists find the 'missing heat' of global warming 700 meters below the sea
(03/28/2013) Critics of climate change often claim that warming has stopped since the late 1990s. While this is categorically false (the last decade was the warmest on record and 2005 and 2010 are generally considered tied for the warmest year), scientists do admit that warming hasn't occurred over land as rapidly as predicted in the last ten years, especially given continually rising greenhouse gas emissions. But a recent study in Geophysical Research Letters has found this so-called missing heat: 700 meters below the surface of the ocean.
