Warnings of global ecological tipping points may be overstated
(03/05/2013) There's little evidence that the Earth is nearing a global ecological tipping point, according to a new Trends in Ecology and Evolution paper that is bound to be controversial. The authors argue that despite numerous warnings that the Earth is headed toward an ecological tipping point due to environmental stressors, such as habitat loss or climate change, it's unlikely this will occur anytime soon—at least not on land. The paper comes with a number of caveats, including that a global tipping point could occur in marine ecosystems due to ocean acidification from burning fossil fuels. In addition, regional tipping points, such as the Arctic ice melt or the Amazon rainforest drying out, are still of great concern.
New York Times slashes environmental coverage
(03/05/2013) On Friday at 5 PM the New York Times announced it was shutting down it Green blog, which highlighted diverse stories online, from energy to endangered species to climate change. The loss of the New York Times environment blog follows shortly after the paper announced it was dismantling its environment desk and moving all of the reporters to other beats.
Global warming to open new Arctic sea lanes
(03/05/2013) Rapidly melting sea ice in the Arctic due to global warming will open new shipping lanes that will speed transit between northern Asia, Europe, Canada and Alaska but unleash new safety, environmental and legal issues, according to scientists writing in this week's issue of the Proceedings of the National Academy of Sciences.
Tokelau, 1st county with 100% renewable energy, leads call for climate action
(03/02/2013) The tiny territory of Tokelau is today leading a call by 14 Pacific island nations for the world to take action to stop climate change.
Leatherback sea turtles suffer 78 percent decline at critical nesting sites in Pacific
(02/27/2013) The world's largest sea turtle, the leatherback (Dermochelys coriacea), is vanishing from its most important nesting sites in the western Pacific, according to a new study in Ecosphere. Scientists found that leatherback turtle nests have dropped by 78 percent in less than 30 years in the Bird's Head Peninsula on the island of New Guinea. Worryingly, these beaches account for three-fourths of the western Pacific's distinct leatherback population; globally the leatherback is listed as Critically Endangered by the IUCN Red List, the highest rating before extinction.
Scientists: stop treating population growth as a 'given' and empower women
(02/27/2013) Climate change, biodiversity loss, resource depletion, water scarcity, and land issues: almost all of the world's environmental problems are underpinned by too many people inhabiting a finite planet. A new study in the Proceedings of the Royal Society B warns that overpopulation—combined with over-consumption—is threatening to push the entire globe into "a collapse of global civilization." But cultural changes, especially more empowerment of women and access to contraceptives, may hold the key to reducing population growth and eventual sustainability.
Good news about climate change? Evolving technology could make cleaning the air more profitable than fouling it
(02/26/2013) In the wake of the hottest and driest summer in memory throughout much of North America, and Super-storm Sandy that flooded cities and ravaged large swaths of the Mid-Atlantic coast, many now recognize that the climate change isn’t just real, but that it is already at our doorstep. As this realization continues to sink in, the political will may ripen to take more aggressive action to put a brake CO2 emissions. Already, President Obama, who had remained mostly silent on the issue during his reelection campaign, has made it clear that tackling climate change will be among his top second-term priorities. But the fact remains that even if the entire world switched magically to 100 percent solar and other non-polluting power sources tomorrow, it’s too late to roll back some of the impacts of climate change.
Rise in 1.5 degrees Celsius likely to spark massive greenhouse gas release from permafrost
(02/25/2013) While nations around the world have committed to keeping temperatures from rising 2 degrees Celsius (3.6 degrees Fahrenheit) above the pre-industrial era, new research published in Science suggests that the global climate could hit a tipping point at just 1.5 degrees Celsius (2.5 degrees Fahrenheit). Studying cave stalactites and stalagmites in Siberia, scientists found that at about 1.5 degrees Celsius the Siberian permafrost melts, potentially releasing a greenhouse gas bomb of 1,000 giga-tonnes, according to some experts.
Full Product Transparency: Cutting the Fluff Out of Sustainability - Book Review
(02/25/2013) Full Product Transparency: Cutting the Fluff Out of Sustainability, by Ramon Arratia, Sustainability Director, Interface, provides us with a clear, concise challenge.
Featured video: moving green, local energy forward in Southeast Asia
(02/25/2013) A new video highlights the work and drive of renewable energy proponents at the inaugural meeting of Southeast Asia Renewable Energy People’s Assembly (SEAREPA) in the Malaysian state of Sabah. Held last year, the meeting brought together 80 organizations from 12 countries to discuss the potential and challenges of green energy in the region. The idea of SEAREPA came about after activists in Sabah successfully defeated plans for a coal-fired power plant to be built adjacent to old-growth rainforest and one of the world's most biodiverse coral reefs.
Arctic sea ice volume plunges over a third in less than 10 years
(02/18/2013) Few places are changing as rapidly as the Arctic due to global warming. Last year, scientists were stunned when the Arctic's seasonal ice extent fell to record low that was 18 percent below the previous one set in 2007. But new research in Geophysical Research Letters finds that the volume of ice is melting away just as quickly: satellite and ocean-based measurement have found that Arctic sea ice has fallen by 36 percent in Autumn since 2003. In winter, the ice volume has dropped 9 percent.
Over 35,000 march on Washington demanding climate action and rejection of Canada's 'carbon bomb'
(02/18/2013) Yesterday over 35,000 people rallied in Washington D.C. for urgent action on climate change, which, according to organizers, was the largest climate march in U.S. history. Activists called on the Obama Administration to do much more to tackle climate change, including rejecting the Keystone XL Pipeline, which would bring carbon-heavy tar sands oil from Canada through the U.S. to a world market.
Will Amazon species lose the climate change race?
(02/14/2013) Deforestation could increase the risk of biodiversity loss in the Amazon by forcing species to migrate further in order to remain at equilibrium with changing climates, says new research. "As migration models are made more realistic through the inclusion of multiple climatic, biotic, abiotic and human factors, the predicted distances between current and future climate analogues invariably increases," Kenneth Feeley, lead author of the paper published in Global Change Biology, told mongabay.com.
Obama connects climate science and policy in State of the Union
(02/13/2013) After several years of silence on climate change, U.S. President Barack Obama has begun speaking out following his re-election last November. The President surprised many by giving climate change a central role in his inauguration speech last month, and he followed-up in his State of the Union speech last night when he called on congress to "pursue a bipartisan, market-based solution to climate change," but added that the administration would take action itself if congress failed.
Head of IMF: climate change is 'the greatest economic challenge of the 21st century'
(02/06/2013) Climate change not debt or austerity is "the greatest economic challenge of the 21st Century," according to Christine Lagarde, the head of the International Monetary Fund (IMF). Speaking at the World Economic Forum in Davos, Switzerland, Lagarde painted a stark picture of the challenges the world faces when up against rising temperatures.
U.S. proposes to list wolverine under Endangered Species Act
(02/05/2013) Arguably one of the toughest animals on Earth, the wolverine (Gulo gulo) may soon find itself protected under the U.S.'s Endangered Species Act (ESA) as climate change melts away its preferred habitat. Last week, the U.S. Fish and Wildlife Service (FWS) announced it was proposing to place the world's largest terrestrial mustelid on the list. Only 250-300 wolverines are believed to survive in the contiguous U.S.
Lean Design Management: Applications to Natural Resource Management
(02/04/2013) Lean Design Management is a design management process that is applied most often within the construction sector. Its applicability to natural resources management is evident through the similarities between construction management and natural resources management.
China responsible for 46 percent of global coal consumption
(01/30/2013) A new chart by the U.S. Energy Information Administration shows how China's coal habit has grown to such an extent that it now accounts for 46.9 percent of the world's consumption. In 2011 coal consumption hit 3.8 billion tons in China, making up nearly half the world's coal use of 8.1 billion tons. Coal comes with a number of environmental issues—including toxic air and water pollution—but the most pressing globally is climate change.
Controversial research outlines physics behind how forests may bring rain
(01/30/2013) It took over two-and-a-half-years for the journal Atmospheric Chemistry and Physics to finally accept a paper outlining a new meteorological hypothesis in which condensation, not temperature, drives winds. If proven correct, the hypothesis could have massive ramifications on global policy—not to mention meteorology—as essentially the hypothesis means that the world's forest play a major role in driving precipitation from the coast into a continent's interior. The theory, known as the biotic pump, was first developed in 2006 by two Russian scientists, Victor Gorshkov and Anastassia Makarieva of the St. Petersburg Nuclear Physics, but the two have faced major pushback and delays in their attempt to put the theory before the greater scientific community.
Scientists could name every species on Earth in 50 years
(01/28/2013) A bold new paper in Science argues that the world's species could be named and described before they vanish into extinction, though the threat of eventual extinction will remain for many, especially as climate change worsens. The scientists say that contrary to popular belief, there are more taxonomists working than ever before and there are likely less species on Earth than often reported, making finding and naming the world's species within reach this century.
Cute koalas have become 'urban refugees'
(01/28/2013) According to Susan Kelly, koalas have become "urban refugees," under siege by expanding cities that bring with them deforestation, dogs, traffic, and other ills for native wildlife. Director of Global Witness, and writer, producer and director of the new documentary Koala Hospital, Kelly has spent 3 years working to understand the rising threats to one of the world's most beloved marsupials. While Koala Hospital highlights the many perils facing koalas, including climate change due to record fires across Australia, it also looks at the efforts of individuals who work to save koalas one—by—one at Port Macquarie Koala Hospital, taking in patients who have been orphaned, hit by cars, scarred in fires, or attacked by dogs.
Energizing Sustainable Cities: Assessing Urban Energy - book review
(01/28/2013) Energizing Sustainable Cities: Assessing Urban Energy, edited by Arnulf Grubler and David Fisk, is a very well written book describing challenges and opportunities to define, analyze, and implement sustainable energy development for 21st Century urban centers. Urban populations, while roughly 50% of the global population, consume over 75% of the globe's energy. Therefore, developing frameworks to assess, analyze and implement sustainable energy systems that meet the criteria for these urban populations is foundational to mitigating climate change, halting biodiversity loss, and improving water quality globally.
Global warming - 56 million years ago
(01/23/2013) Sandy, Irene, Katrina... Hurricanes are fast becoming household names and have many people worried over the connection between extreme weather and the amount of greenhouse gases people are pumping into the atmosphere. No one can predict for sure what will happen decades or centuries from now as such gas concentrations increase. But scientists have a pretty good picture of what did happen in the past; greenhouses gases were released into the atmosphere in massive amounts at least once before—around 56 million years ago.
Climate change melting glaciers in the Andes
(01/22/2013) Glaciers are melting faster than ever in the tropical Andes, warns a new study published in The Cryosphere, which puts the blame for vanishing glaciers squarely on climate change. The study — the most comprehensive to date — found that since the 1970s glacier melt in the region has been speeding up, threatening freshwater supplies in Peru and Bolivia.
Obama: 'We will respond to the threat of climate change'
(01/21/2013) In Obama's second inauguration speech today, the newly re-elected president of the U.S. reaffirmed his commitment to taking action on climate during his second term. Noting that ignoring climate change would "betray our children and future generations," Obama argued whole-heartedly for a transition to clean energy.
Asia's third largest animal may be on the rebound
(01/17/2013) Unlike Asia's largest animal (the elephant) and its second largest (the rhino), the wild yak—the third largest animal on the world's biggest continent—rarely makes headlines and is never paraded by conservation groups to garner donations. Surviving on the top of the world, in the Tibetan-Qinghai Plateau, the wild yak (Bos mutus) lives it life out in such obscurity that even scientists know almost nothing about it.
NASA says 2012 was the 9th warmest year since 1880, blames global warming
(01/15/2013) 2012 was the ninth warmest year since annual record-keeping began in 1880 say NASA scientists who cited rising greenhouse gas emissions as the chief culprit.
Soot is second biggest man-made contributor to global warming
(01/15/2013) Soot is the second largest man-made contributor to global warming, according to a comprehensive new study published in the Journal of Geophysical Research: Atmospheres.
Climate change already pummeling U.S. according to government report
(01/14/2013) Climate change is on the march across the U.S. according to a new draft report written by U.S. government scientists with input from 240 experts. It documents increasing and worsening extreme weather, rising sea levels, and ocean acidification among other impacts. Released Friday for public review, the report will be officially launched later this year or early in 2014.
A second look at 'Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors'
(01/14/2013) Fewer, Richer, Greener: The End of the Population Explosion and the Future for Investors (November/December 2012, Vol. 68, No. 6: 20–37), by Mr. Laurence B. Siegel provides us with a commentary of population explosion and green investment opportunities over the long-run.
Paradigm shift needed to avert global environmental collapse, according to author of new book The Blueprint: Averting Global Collapse
(01/10/2013) Global strategist, trained educator, and international lecturer Daniel Rirdan set out to create a plan addressing the future of our planet. His book The Blueprint: Averting Global Collapse, published this year, does just that. "It has been a sixty hour a week routine," Rirdan told mongabay.com in a recent interview. "Basically, I would wake up with the burden of the world on my shoulders and go to sleep with it. It went on like this for eighteen months." It becomes apparent when reading The Blueprint that it was indeed a monumental undertaking.
Australia reels from record heatwave, fires
(01/09/2013) Yesterday Australia recorded its highest average temperature yet: 40.33 degrees Celsius (104.59 Fahrenheit). The nation has been sweltering under an unprecedented summer heatwave that has spawned wildfires across the nation, including on the island of Tasmania where over 100 houses were engulfed over the weekend. Temperatures are finally falling slightly today, providing a short reprieve before they are expected to rise again this weekend.
2012 was America's warmest year on record
(01/08/2013) 2012 was the warmest year on record for the contiguous U.S. according to the National Oceanic and Atmospheric Administration (NOAA).
Mountain pine beetle threatening high-altitude, endangered trees
(01/02/2013) In the western U.S., few trees generally grow in higher altitudes than the whitebark pine (Pinus albicaulis). Providing shelter and food for bears, squirrels and birds, the whitebark pine ecosystems also help regulate water flow from snowmelt. But, according to a new study in the Proceedings of the National Academy of Sciences (PNAS), climate change has produced a novel threat for these high-altitude forests : mountain pine beetles (Dendroctonus ponderosae).
Top 10 Environmental Stories of 2012
(12/18/2012) Below is a quick review of some of the biggest environmental stories of 2012. The 'top stories' are listed in no particular order. Climate change, overpopulation, consumption, and ecological destruction is pushing planet Earth toward a tipping point according to a major study in Nature released over the summer. This could result in a new 'planetary state' that would be far harsher and bleaker than the current one (beginning around 12,000 years ago), which saw the rise and success of human society.
99.999% chance 2012 will be hottest year on record for continental U.S
(12/13/2012) 2012 will almost certainly be the hottest year on record across the 48 contiguous United States, says a new analysis published by Climate Central.
Climate Summit in Doha characterized by lack of ambition
(12/09/2012) Ahead of the 18th United Nations Framework Convention on Climate Change (UNFCCC) in Doha, Qatar a variety of reports warned that the world was running out of time to avoid dangerous climate change, and that there was a widening gap between what nations have pledged to do and what the science demanded. A landmark report by the World Bank painted an almost apocalyptic picture of a world in which global temperatures have risen 4 degrees Celsius above pre-industrial levels, including unprecedented heatwaves and droughts, rising sea levels, global agriculture crises, and a stunning loss of species. In addition, scientific studies released near the two week conference found that sea levels were rising 60 percent faster than predicted, forests around the world were imperiled by increasing drought, marine snails were dissolving in the Southern Ocean due to ocean acidification, and ice melt in Greenland and Antarctica was on the rise.
Illegal logging, mining worsened impact of Philippines' killer typhoon
(12/06/2012) According to Filipino officials, rampant illegal logging and mining were likely a part of the cause for the high casualty count from Category 5 Typhoon Bopha (Pablo), especially in the Compostela Valley where government officials had warned people to stop the illegal activities. So far, 370 people have been found dead on the island of Mindanao with another 400 missing. Waters rose so high even emergency shelters were inundated.
Wealthy nations' fossil fuel subsidies dwarf climate financing
(12/05/2012) A new analysis finds that 21 wealthy countries spent five-times more on subsidizing fossil fuels in 2011 than they have on providing funds for poor nations to cut greenhouse gas emissions and adapt to the impacts of climate change. The analysis, by Oil Change International, comes in the midst of the current UN Climate Summit held in Doha, Qatar; progress at the talks has been stymied due to the gulf between poor and rich nations, including on the issue of climate financing.
Animals dissolving due to carbon emissions
(12/03/2012) Marine snails, also known as sea butterflies, are dissolving in the Southern Seas due to anthropogenic carbon emissions, according to a new study in Nature GeoScience. Scientists have discovered that the snail's shells are being corroded away as pH levels in the ocean drop due to carbon emissions, a phenomenon known as ocean acidification. The snails in question, Limacina helicina antarctica, play a vital role in the food chain, as prey for plankton, fish, birds, and even whales.
'No-one is listening to the entire scientific community': global carbon emissions set to hit new high
(12/03/2012) Global carbon dioxide (CO2) emissions from industrial sources are set to hit a new record high this year according to a new analysis by Global Carbon Project. The analysis in Nature Climate Changes predicts that CO2 emissions will rise another 2.6 percent, hitting 35.6 billion tonnes. The scientists warn that such steep climbs in global emissions year-after-year means that the door is rapidly closing on a global agreement to keep temperatures from rising 2 degree Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
Science and Public Reason - book review
(12/03/2012) Professor Sheila Jasanoff’s superb treatise Science and Public Reason, part of Earthscan's, is a wonderful book describing, through a collection of her essays and articles from the past 25-years, the rise of the field of Science and Technology Studies. The book could not have arrived soon enough, as we now globally face the triple threat of 1) massive biodiversity loss, 2) nutrient cycling disruption (greenhouse gases, Montreal Protocol gases, nitrogen fertilizer caused eutrophication, etc.), and 3) water quality degradation (saltwater intrusion, depleted aquifers, lack of clean drinking water, etc.).
Greenland and Antarctica ice melt accelerating, pushing sea levels higher
(12/03/2012) A massive team of scientists have used multiple methods to provide the best assessment yet of ice loss at the world's poles, including Greenland and a number of Antarctic ice sheets. Their findings—that all major ice sheets are shrinking but one; that ice loss is speeding up; and that this is contributing to the rise in sea levels—add more evidence to the real-time impacts from global climate change. Melting ice sheets at the poles have raised sea levels 11.1 millimeters, or about 20 percent of observed sea level rise, in the past twenty years, according to the landmark study in Science.
Reduction in snow threatens Arctic seals
(11/28/2012) Arctic snowfall accumulation plays a critical role in ringed seal breeding, but may be at risk due to climate change, according to a new study in Geophysical Research Letters. Sea ice, which is disappearing at an alarming rate, provides a crucial platform for the deep snow seals need to reproduce. Ringed seals (Phoca hispida) require snow depths of at least 20 centimeters (8 inches): deep enough to form drifts that seals use as birth chambers.
Watery world: sea level rising 60 percent faster than predicted
(11/28/2012) Sea levels are rising 60 percent faster than Intergovernmental Panel on Climate Change (IPCC) has estimated, according to a new study in the open access Environmental Research Letters. In addition to imperiling coastal regions and islands, global sea level rise is worsening the damage inflicted by extreme weather such as Hurricane Sandy, which recently brought catastrophic flooding to the New Jersey coast and New York City.
Organic farming keeps carbon out of the atmosphere
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
Hopes pinned on Obama again as Doha Climate Summit opens
(11/26/2012) A number of observers have expressed hope that the Obama Administration, fresh from a re-election victory in the U.S., will take a more active and ambitious role at this year's UN Climate Summit, held in Doha, Qatar. The summit opens amid fresh—and increasingly dire—warnings over climate change from the World Bank, the International Energy Agency, and the UN itself.
Unique program to leave oil beneath Amazonian paradise raises $300 million
(11/26/2012) The Yasuni-ITT Initiative has been called many things: controversial, ecological blackmail, revolutionary, pioneering, and the best chance to keep oil companies out of Ecuador's Yasuni National Park. But now, after a number of ups and downs, the program is beginning to make good: the Yasuni-ITT Initiative has raised $300 million, according to the Guardian, or 8 percent of the total amount needed to fully fund the idea.
China and India plan 818 new coal plants
(11/26/2012) Even as the clamor to reduce greenhouse gas emissions reaches a new high—echoed recently by such staid institutions as the World Bank and the International Energy Agency (IEA)—a new analysis by the World Resources Institute (WRI) finds that 818 new coal-fired plants are under proposal in China and India. In all 1,199 new coal-fired plants are currently planned worldwide, according to the report, totaling 1.4 million megawatts of energy.
As Doha Climate Summit kicks off, more ambitious cuts to greenhouse gas emissions needed
(11/26/2012) As the 18th meeting of the UN Framework Convention on Climate Change (UNFCCC) kicks off this morning in oil and gas rich Qatar, the world body warns that much more ambitious greenhouse gas cuts are needed to keep catastrophic climate change at bay. A new report by the UN Environment Program (UNEP) and the European Climate Foundation finds that even if all current emissions pledges are kept, the world will still spew 8 billion tonnes of CO2 equivalent above what is needed by 2020, putting the globe on a fast-track to dangerous climate change.
