(11/11/2013) While many of the world's national governments move tepidly (if at all) to combat climate change, cities are showing increasing leadership. The San Francisco Bay Area's Air District Board signed off last week on a measure to cut greenhouse gas emissions by 80 percent within less than 40 years time as based on 1990 levels. The measure follows the same goal as an executive order made by California governor, Arnold Schwarzenegger, in 2005.
Amazon deforestation could cause droughts in California
(11/08/2013) Complete deforestation of the Amazon rainforest could reduce rainfall in the Pacific Northwest by up to 20 percent and snowpack in the Sierra Nevada by up to 50 percent, suggests new research published in the Journal of Climate. The study is based on high resolution computer modeling that stripped the Amazon of its forest cover and assessed the potential impact on wind and precipitation patterns. While the scenario is implausible, it reveals the global nature of the ecological services afforded by the world's largest rainforest.
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.
Featured video: trailer for James Cameron's new global warming series
(11/05/2013) Showtime has recently released its first trailer for the network's new series on the impacts of global warming worldwide, entitled Years of Living Dangerously. The series, which will debut in April 2014, had employed some of America's most well-regarded politicians, journalists, intellectuals, and actors to tell how climate change is already impacting communities around the world.
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.
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.
Shanghai to ban coal by 2017
(10/28/2013) China's largest city and one of the world's biggest, Shanghai, is set to ban coal burning in just four years, according to a new Clean Air Action Plan. The city-wide ban on coal burning is one effort among many to get Shanghai's infamous smog under control as well as another sign that China has begun to take its pollution problems more seriously.
First study of little-known mammal reveals climate change threat
(10/28/2013) One of the world's least-known flying foxes could face extinction by rising seas and changing precipitation patterns due to global warming, according to a new study in Zookeys. The research, headed by Donald Buden with the College of Micronesia, is the first in-depth study of the resident bats of the remote Mortlock Islands, a part of the Federated States of Micronesia.
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.
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.
France upholds nationwide ban on fracking
(10/14/2013) France's landmark ban on fracking has survived constitutional challenges lobbed by U.S.-company, Schuepbach Energy. On Friday, the nation's Constitutional Council decided that the ban did not violate France's constitution. Passed in 2011 under then President Nicolas Sarkozy, the ban has since been upheld by current President Francios Hollande.
Sea and storm: coastal habitats offer strongest defense
(10/11/2013) Surging storms and rising seas threaten millions of U.S. residents and billions of dollars in property along coastlines. The nation's strongest defense, according to a new study by scientists with the Natural Capital Project at the Stanford Woods Institute for the Environment, comes from natural coastal habitats.
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.
Russia charges non-violent activists with 'piracy' for protesting Arctic oil drilling
(10/07/2013) In what is being described by Greenpeace as an 'imaginary offense,' Russia has charged 30 people with piracy after activists protested against oil exploitation in the Arctic. The 30 charged included not only protestors, but a British journalist and Russian videographer who were on board Greenpeace's ship, the Arctic Sunrise, when it was stormed by the Russian military late last month.
Myanmar faces new conservation challenges as it opens up to the world
(10/04/2013) For decades, one of Southeast Asia's largest countries has also been its most mysterious. Now, emerging from years of political and economic isolation, its shift towards democracy means that Myanmar is opening up to the rest of the world. Myanmar forms part of the Indo-Burma biodiversity hotspot, and some of the largest tracts of intact habitat in the hotspot can be found here.
Climate change could increase diarrheal disease in Botswana
(10/03/2013) Climate change may increase the incidence of diarrheal disease in Botswana, according to a recent study in the International Journal of Environmental Research and Public Health. "Diarrheal disease is a very important public health problem in Botswana," said lead author Kathleen Alexander, who led a unique 30-year analysis (1974-2003) on the incidence of diarrhea in Botswana. "As a water-restricted country, Botswana is predicted to be heavily impacted by climate change.
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.
Climate change pushing tropical trees upslope 'exactly as predicted'
(09/27/2013) Tropical tree communities are moving up mountainsides to cooler habitats as temperatures rise, a new study in Global Change Biology has found. By examining the tree species present in ten one-hectare plots at various intervals over a decade, researchers found that the proportion of lowland species increased in the plots at higher elevations. The study, which was undertaken in Volcan Barva, Costa Rica, adds to a growing body of evidence that climate change is having an impact on species range distributions.
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.
Climate change policy is just good economics
(09/25/2013) For the majority of the new century, Americans have largely stopped caring about the environment. In that time, America has suffered 9/11, two of the nation's four longest wars, the deepest depression in 80 years, increased inequality, and incompetent or fractured leadership. There's been a lot on the public mind.
Climate change to hurt children most
(09/25/2013) Children will bear the brunt of the impact of climate change because of their increased risk of health problems, malnutrition and migration, according to a new study published on Monday. And food prices are likely to soar as a result of warming, undoing the progress made in combating world hunger.
Climate change could kill off Andean cloud forests, home to thousands of species found nowhere else
(09/18/2013) One of the richest ecosystems on the planet may not survive a hotter climate without human help, according to a sobering new paper in the open source journal PLoS ONE. Although little-studied compared to lowland rainforests, the cloud forests of the Andes are known to harbor explosions of life, including thousands of species found nowhere else. Many of these species—from airy ferns to beautiful orchids to tiny frogs—thrive in small ranges that are temperature-dependent. But what happens when the climate heats up?
'Heading towards an ice-free Arctic': sea ice extent hits sixth lowest on record
(09/18/2013) Sea ice cover in the Arctic shrank to one of its smallest extents on record this week, bringing forward the days of an entirely ice-free Arctic during the summer. The annual sea ice minimum of 5,099m sq km reached on 13 September was not as extreme as last year, when the collapse of sea ice cover broke all previous records.
African grass could substantially cut greenhouse gas emissions from livestock industry
(09/17/2013) Scientists will call for a major push this week to reduce the amount of greenhouse gas emissions from agriculture through the use of a modified tropical grass. Brachiaria grasses have been found to inhibit the release of nitrous oxide, which has a more powerful warming effect than carbon dioxide or methane, leading them to be called a super grass.
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.
Mesoamerican Reef needs more local support, says report
(09/13/2013) From massive hotel development through the agriculture industry, humans are destroying the second largest barrier reef in the world: the Mesoamerican Reef. Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change.
Natural cooling cycle in Pacific may have slowed global warming...for now
(09/12/2013) Cooling waters in the tropical Pacific Ocean appear to be a major factor in dampening global warming in recent years, scientists said on Wednesday. Their work is a big step forward in helping to solve the greatest puzzle of current climate change research – why global average surface temperatures, while still on an upward trend, have risen more slowly in the past 10 to fifteen years than previously.
Global warming may ‘flatten’ rainforests
(09/12/2013) Climate change may push canopy-dwelling plants and animals out of the tree-tops due to rising temperatures and drier conditions, argues a new study published in Proceedings of the Royal Society B. The development may be akin to 'flattening' the tiered vegetation structure that characterizes the rainforest ecosystem.
Indonesian villagers sue president over climate change
(09/11/2013) Eight Indonesian villagers have sued the country’s president and a number of other high-level government officials over the impacts of climate change and environmental destruction in their province, reports Mongabay-Indonesia. The villagers say they have suffered health problems, experienced financial losses and seen a general decline in their quality of life due to forest and peatland clearing, and they are pinning the blame on some of Indonesia’s highest elected and appointed officials.
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?
Whale shark mapping: scientists uncover global distribution for the largest fish in the world
(08/27/2013) Polka-dotted and striped. Massive but docile. That’s the whale shark for you - the largest fish and shark in the world. But despite being major tourist attractions, the lives of these awe-inspiring creatures of the ocean remain far from being demystified. However, a team of researchers from Australia may now have some answers to where these whale sharks (Rhinocodon typus) occur.
Activists propose naming hurricanes after politicians who deny climate change
(08/27/2013) Environmental activists are petitioning the World Meteorological Organization (WHO) to start naming storms after policy makers who deny human's role in driving climate change.
Yasuni could still be spared oil drilling
(08/26/2013) When Ecuadorean President, Rafael Correa, announced on August 15th that he was abandoning an innovative program to spare three blocs of Yasuni National Park from oil drilling, it seemed like the world had tossed away its most biodiverse ecosystem. However, environmental groups and activists quickly responded that there may be another way to keep oil companies out of Yasuni's Ishpingo-Tambococha-Tiputini (ITT) blocs: a national referendum.
Google Earth presents fish-eye view of coral reefs
(08/20/2013) You can now visit up-close and personal some of the world's most imperiled ecosystems on Google Earth: coral reefs. The Google team is working with scientists to provide 360 degree panoramas, similar to Google street-view, to give armchair ecologists a chance to experience the most biodiverse ecosystems under the waves.
Climate change killing harp seal pups
(08/20/2013) As sea ice levels continue to decline in the northern hemisphere, scientists are observing an unsettling trend in harp seal young mortalities regardless of juvenile fitness. While a recent study found that in harp seal breeding regions ice cover decreased by up to 6% a decade from 1979 on, a follow-up study in PLoS ONE compared the rate of harp seal strandings to total ice cover from 1992 to 2010.
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.
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.
Worst drought in 30 years threatens millions in southern Africa with food insecurity
(08/19/2013) Around 2 million people face food insecurity in northern Namibia and southern Angola as the worst regional drought in decades takes its toll, according to the UN. Two years of failed rains have pushed families into desperate conditions in a region already known for its desert-like conditions. In Namibia alone, experts estimate that over 100,000 children under five are at risk for acute malnutrition.
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.
Zoo races to save extreme butterfly from extinction
(08/15/2013) In a large room that used to house aquatic mammals at the Minnesota Zoo, Erik Runquist holds up a vial and says, 'Here are its eggs.' I peer inside and see small specks, pale with a dot of brown at the top; they look like a single grain of cous cous or quinoa. Runquist explains that the brown on the top is the head cap of the larva, a fact that becomes more clear under a microscope when you can see the encased larva squirm. I'm looking at the eggs of a Poweshiek skipperling, a species that is more imperiled than pandas, tigers, or bluewhales. Once superabundant, only several hundred Poweshiek skipperlings may survive on Earth today and the eggs I'm looking at are the only ones in captivity.
Fracking sucks up all the water from Texas town
(08/15/2013) Beverly McGuire saw the warning signs before the town well went dry: sand in the toilet bowl, the sputter of air in the tap, a pump working overtime to no effect. But it still did not prepare her for the night last month when she turned on the tap and discovered the tiny town where she had made her home for 35 years was out of water.
Climate change to increase violent crime
(08/06/2013) Bring on the cool weather – climate change is predicted to cause extreme weather, more intense storms, more frequent floods and droughts, but could it also cause us to be more violent with one another?
Journey to the Edge of Eden: the struggle to preserve Southwest Florida
(08/05/2013) Gary Schmelz, in a Journey to the Edge of Eden, takes us through a wonderful personal account of the conservation history of Southwest Florida. Journey to the Edge of Eden is one part personal memoir similar to the English naturalist Gerald Durrell and one part Florida conservation history. With hilarious stories of unintended naturalist misadventures and recounting conservation “as it happened,” a Journey to the Edge of Eden is one of those rare books you read in a coffee shop and with gusto and pride while laughing along out loud at Gary Schmelz stories.
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.
