Study finds soil releases carbon for decades after forests are felled
(03/11/2015) According to a study by researchers with Dartmouth College, the carbon stored in mineral soils, which lie underneath the organic soil layer, is released for decades after a forest is cut down. This may have serious implications for how carbon emissions from deforestation are accounted for.
Hunters and birdwatchers make good conservationists in the U.S.
(03/11/2015) What do hunters and birdwatchers have in common? Both groups are much more likely to support conservation than the average rural American, according to new research published in the Journal of Wildlife Management.
Arctic upheaval: new book outlines challenges at the top of the world
(02/16/2015) For most of us, the Arctic is not at the front of our minds. We view it as cold, stark, and, most importantly, distant. Yet, even in an age of vast ecological upheaval, one could argue that no biome in the world is changing so rapidly or so irrevocably. Two hundred plus years of burning fossil fuels has warmed up the top of our planet more quickly than anywhere else.
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.
Feds confirm first wolf in the Grand Canyon area shot dead
(02/12/2015) Last fall, tourists to the north rim of the Grand Canyon reported seeing a gray wolf. The only problem was there had been no wolves in the area for over 70 years. Still, it turned out the animal in question was not a coyote or stray dog, but, indeed a female gray wolf known as "914F". She had migrated hundreds of miles from the northern Rockies. Unfortunately, this was near the end of her story.
Super-rare carnivore photographed in Yosemite after missing for nearly a century
(02/03/2015) For years, biologists believed the Sierra Nevada fox was down to a single population of around 20 animals in California's Lassen Volcanic National Park. But then in 2010, biologists found a small population near Sonora Pass. Now, more good news: last week, scientists documented the first Sierra Nevada fox in Yosemite National Park in nearly 100 years.
Monarch butterfly population rises a little, but still perilously low
(01/28/2015) The world's migrating monarch butterfly population has bounced back slightly from its record low last year, but the new numbers are still the second smallest on record. According to WWF-Mexico and the Mexican government, butterflies covered 2.79 acres (1.13 hectares) in nine colonies this year in the Mexican forests where the insects overwinter.
Scientists call on Obama to stop logging in old growth forests
(01/27/2015) Seven conservation societies have joined a campaign to push the Obama administration to end old-growth forest logging in Alaska's Tongass National Forest.
Accounting for natural capital on financial exchanges
(01/26/2015) Last month, Norway's stock exchange, the Oslo Børs, introduced a way for investors to use their money to promote sustainability. A new list by the stock exchange highlights green bonds, financial products issued by companies to raise capital for environmentally friendly projects. Notably, the list requires that issuing companies obtain and publicize outside opinions on the projects' environmental features.
Changing California forests may help us prepare for the future
(01/21/2015) A new study published by the Proceedings of the National Academy of Sciences examines how California’s forests have changed since the 1930s--and, according to its authors, can help us understand how forests will respond to the changing global climate in the future.
Judge protects Midwest wolves after 1,599 killed in three years
(01/06/2015) Future wolf hunting and trapping seasons in the Upper Midwest are on hold after a judge ruled the Obama Administration erred in removing the top predator from the Endangered Species Act. The ruling came nearly three years after the U.S. Fish and Wildlife Service dropped federal protections for the Great Lakes' wolf population. Since then hunters and trappers have killed 1,599 wolves.
Two vanishing prairie butterflies added to the Endangered Species Act
(01/05/2015) This fall, the U.S. Fish and Wildlife Service added two little-known prairie butterflies to the Endangered Species Act. One of the species, the Poweshiek skipperling, may be down to only a few hundred individuals. The Dakota skipperling is faring a little better, but both have lost the majority of their habitat in the pass few hundred years and continue to decline.
Top 10 HAPPY environmental stories of 2014

'Canary in the cornfield': monarch butterfly may get threatened species status
(09/08/2014) Monarch butterflies were once a common sight throughout the North American heartland. But declines in milkweed – their caterpillars’ only source of food – have led to a 90 percent decline in monarch numbers. Now, the U.S. Fish and Wildlife Service is reviewing a petition that would grant the iconic species protection through the Endangered Species Act.
The last of her kind: centennial of the death of the world's last passenger pigeon
(09/01/2014) They once numbered in the billions, flying 60 miles per hour in flocks that darkened the sky. But on September 1, 1914, one hundred years ago today, the last member of what may have been the most numerous bird species on the planet died in a cage in the Cincinnati zoo.
Invasion of the lionfish: new research finds the situation may be worse than we thought
(08/27/2014) You may have recently read the controversial story on invasive lionfish research involving Dr. Zack Jud of Florida International University and a young girl named Lauren Arrington. While the issue of attribution in scientific research is crucial to the discipline, much of the media focus so far has sidestepped the real issue: what lionfish tolerance for brackish water really means for the environment.
How do we save the world's vanishing old-growth forests?
(08/26/2014) There's nothing in the world like a primary forest, which has never been industrially logged or cleared by humans. They are often described as cathedral-like, due to pillar-like trees and carpet-like undergrowth. Yet, the world's primary forests—also known as old-growth forests—are falling every year, and policy-makers are not doing enough to stop it.
Invasive species worsen damage from Hawaii's storms
(08/22/2014) Damage from Hurricane Iselle, which recently battered Hawaii's Big Island, was exacerbated by invasion of non-native tree species, say experts who have studied the transformation of Hawaii's native forests. selle, which made landfall on the Big Island on August 7, was the third-strongest tropical cyclone to hit Hawaii since 1950. It caused upwards of $50 million in damage.
Planting meadows in the ocean: technique may help restore disappearing seagrass beds

U.S should sanction Mozambique for its role in elephant, rhino poaching, urges NGOs
(07/03/2014) Two prominent NGOs U.S should sanction Mozambique for its role in elephant, rhino poaching, urges NGOsare petitioning the U.S government to slap Mozambique with trade sanctions due to the country's role in regional poaching. The groups contend that Mozambique has done little to combat both its own poaching epidemic or stop its nationals from spilling over the border to kill rhinos and elephants in South Africa and Tanzania.
Global warming puts trillions at stake, but mitigation offers big economic gains
(06/25/2014) Two new reports this week look at the economics of global warming. The first, Risky Business, tallies the cost of climate change to the U.S., including tens-of-billions lost to destruction of coastal property, crop failures, drought, wildfires, and heatwaves. In contrast, the second report, by the World Bank, turns climate change economics on its head.
U.S. raises $800 million for oceans, including $7 million from Leonardo DiCaprio

EPA carbon proposal may be crucial step in addressing global climate change
(06/10/2014) The U.S. Environmental Protection Agency's (EPA) June 2nd regulation proposal hit all the expected chords. Following on the heels of a January regulation for new power plants, the Clean Power Plan focuses on all existing electric generation. By 2030, the plan aims to reduce 2005-level carbon dioxide emissions by 30 percent.
By the bones: herring populations were superabundant before commercial fisheries
(06/09/2014) Scientists analyzed almost half a million fish bones to shed light on the population history of Pacific herring (Clupea pallasii) in the North Pacific Ocean. Their paper reveals a decline of unprecedented scale, and suggests that while the abundance of Pacific herring does fluctuate naturally, their numbers have fallen precipitously since commercial fishing started targeting the species in the 19th century.
New species has its anus behind its head
(06/09/2014) In the dark caves of southern Indiana in the United States, scientists have discovered a new species of cavefish that are blind, pinkish, and have their anus behind their heads.

Trawling: destructive fishing method is turning seafloors to 'deserts'
(05/28/2014) Previous research has linked trawling to significant environmental impacts, such as the harvest of large numbers of non-target species, collectively termed “bycatch,” as well as destruction of shallow seabeds. Now, a new study finds this method is also resulting in long-term, far-reaching consequences in the deeper ocean and beyond.
Upcoming EPA Proposal could put America back on track to lead on global warming
(05/27/2014) A regulation proposal on coal plants that the U.S. Environmental Protection Agency (EPA) will release in June could be great news for the climate change initiative. The EPA rolled out tough regulations on new constructions of electric generation facilities in January, but the nation's 1,500 existing power plants were left unaffected.
Extreme cold and drought in U.S. linked to climate change
(05/23/2014) The U.S. Midwest and Northeast experienced one of the coldest, snowiest winters on record this past season. This might seem contrary to warming trends forecast by climate scientists, but a new analysis released today in Science points out that climate change caused by greenhouse gas emissions may actually have contributed to the well-below average temperatures seen in parts of the U.S.
The quiet zoo revolution
(05/19/2014) A quiet zoo revolution has also been occurring over the past twenty-five years. Rather than just stand by the sidelines as species vanish in the wild, many zoos have begun funding on-the-ground conservation efforts. This revolution signals a widening realization by zoos of the positive—and wholly unique—role they could play in combating global mass extinction. But are zoos doing enough?
53 indigenous activists on trial for police-protester massacre in Peru
(05/15/2014) In the summer of 2009, on a highway in Peru known as Devil's Curve: everything went wrong.

The incredible shrinking salamander: researchers find another casualty of climate change
(04/04/2014) Climate change is contributing to a slew of global problems, from rising seas to desertification. Now, researchers have added another repercussion: shrinking salamanders. Many amphibian populations around the world are currently experiencing precipitous declines, estimated to be at least 211 times normal extinction rates. Scientists believe these declines are due to a multitude of factors such as habitat loss, agricultural contamination, and the accidental introduction of a killer fungus, among others.
U.S. citizens willing to spend billions to protect monarch butterflies
(04/03/2014) New research shows Americans are willing to pay for the protection of the ailing monarch butterfly, which is experiencing a steep decline in numbers.

Death of young Sumatran rhino shouldn't discourage captive breeding efforts say conservationists
(04/01/2014) Just over two weeks ago, conservationists in the Malaysian state of Sabah managed to finally catch a wild Sumatran rhino female after months of failed attempts. But following such hopeful events, comes bad news thousands of miles away: a young female rhino, named Suci, died over the weekend at the Cincinnati Zoo.
Cocaine: the new face of deforestation in Central America
(03/11/2014) In 2006, Mexico intensified its security strategy, forming an inhospitable environment for drug trafficking organizations (also known as DTOs) within the nation. The drug cartels responded by creating new trade routes along the border of Guatemala and Honduras. Soon shipments of cocaine from South America began to flow through the Mesoamerican Biological Corridor (MBC). This multi-national swathe of forest, encompassing several national parks and protected areas, was originally created to protect endangered species, such as Baird's Tapir (Tapirus bairdii) and jaguar (Panthera onca), as well as the world's second largest coral reef. Today, its future hinges on the world's drug producers and consumers.
Greenpeace stunt targets Procter & Gamble’s Cincinnati headquarters over palm oil

Despite frigid cold in U.S., January was the fourth warmest on record worldwide
(02/27/2014) Worldwide, this January was the fourth warmest since record-keeping began, according to new data released by National Oceanic and Atmospheric Administration (NOAA). While parts of the world, most notably eastern North America and northern Russia, experienced temperatures well-below average, overall the month was a scorcher. In fact, another dataset, from NASA's Goddard Institute for Space Studies (GISS), that uses different methodology, found that January was the third warmest since record keeping began.
Obama announces new strategy to tackle wildlife trafficking, including toughening ivory ban
(02/12/2014) Yesterday, the Obama administration announced an ambitious new strategy to help tackle the global illegal wildlife trade, including a near-complete ban on commercial ivory. The new strategy will not only push over a dozen federal agencies to make fighting wildlife trafficking a new priority, but will also focus on reducing demand for wildlife parts and actively engaging the international community. The U.S. is the world's second largest destination for illegal wildlife trafficking after China.

Alaska roasting: new NASA map shows the Final Frontier in grip of January heatwave
(02/05/2014) Alaska got California weather at the end of January, as displayed by a new map based on data by NASA's Terra satellite's Moderate Resolution Imaging Spectroradiometer (MODIS). The U.S. state experiences one of its warmest winter periods on record during the second half of January, including some temperatures that ran 40 degrees Fahrenheit (22 degrees Celsius) above average. According to the EPA, temperatures in Alaska have risen an average of 3.4 degrees Fahrenheit (1.9 degrees Celsius) in just the last 50 years due to climate change.
Migrating monarch butterflies hit shockingly low numbers
(01/31/2014) The monarch butterfly population overwintering in Mexico this year has hit its lowest numbers ever, according to WWF-Mexico. Monarch butterflies covered just 0.67 hectares in Mexico's forest, a drop of 44 percent from 2012 already perilously low population. To put this in perspective the average monarch coverage from 1994-2014 was 6.39 or nearly ten times this year's. For years conservationists feared that deforestation in Mexico would spell the end of the monarch migration, but now scientists say that agricultural and policy changes in the U.S. and Canada—including GMO crops and habitat loss—is strangling off one of the world's great migrations.
Over 2,500 wolves killed in U.S.'s lower 48 since 2011
(01/28/2014) Hunters and trappers have killed 2,567 gray wolves in the U.S.'s lower 48 states since 2011, according to recent data. Gray wolves (Canis lupus) were protected by the Endangered Species Act (ESA) for nearly 40 years before being stripped of their protection status by a legislative rider in 2011. Last year total wolf populations were estimated at over 6,000 in the region.
NASA picture reveals shocking impact of California's drought

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.
Rewilding Chile's savanna with guanacos could increase biodiversity and livestock
(01/06/2014) Local extinctions have occurred across a variety of habitats on every continent, affecting a gamut of species from large predators such as the wolves of North America, to tiny amphibians like the Kihansi spray toad of Tanzania. The long trek toward reversing such extinctions has begun, but it is not without its challenges, both ethical and logistical.

Featured video: U.S. forests decimated for 'green' bio-energy in Europe
(12/12/2013) Wetland forests in the southern U.S. are becoming the victims of a drive for so-called green energy in Europe, according to activist group Dogwood Alliance, which has produced a new video highlighting the issue. The activists contend that bio-energy that depends on chopping down forests not only devastates vital ecosystems, but actually emits more greenhouse gases than traditional fossil fuels.
Average American consumes 50,000 pounds of raw materials annually for the stuff they buy
(12/10/2013) The average American car weighs about 3,000 pounds. But to produce that vehicle, a lot more raw materials were used than its final weight! Maybe as much as 100 times more, as reported by scientists in a recent paper in the Proceedings of National Academy of Science. For this car to be produced, iron ore is mined in Australia and made into steel. Steel is then shipped to Japan and made into a car, which is then sold in the U.S. Most studies until now, measured national consumption by accounting only for the final weight of the products we purchase.
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.
Hedge fund downgrades stock over company's links to illegal logging in Russian Far East
(12/02/2013) A hedge fund manager has downgraded Lumber Liquidators' stock over the company's alleged links to illegal logging in the Russian Far East, reports The Wall Street Journal. Speaking at the Robin Hood Investors Conference on November 22, Whitney Tilson, the founder of Kase Capital Management, said Lumber Liquidators' stock price may be inflated due to purchases of illegally sourced timber from Russia.
Govts pledge $280M to slow deforestation for agriculture
(11/21/2013) The governments of Norway, Britain and the United States pledged $280 million toward a new initiative that aims to reduce emissions associated with forest conversion for agriculture, reports Reuters. The money will come out of previously committed funds for climate change. The initiative, called the BioCarbon Fund Initiative for Sustainable Forest Landscapes and administered by the World Bank, focuses on the 80 percent of deforestation that is driven by agriculture.
Gulf of Mexico deep sea may need decades to recover from oil spill
(11/20/2013) The catastrophic explosion that spewed some five million barrels of oil deep into the Gulf of Mexico in April 2010 will take a heavy toll in the ocean’s lowest layers for years to come. That’s the stark conclusion of seafloor research conducted six months after the Deepwater Horizon oil spill. The study, published on August 7 in PLoS ONE, examined life in the Gulf’s deepest waters near the blowout, about 1.6 kilometers below the surface. Here, the researchers found that the damages will take decades to reverse.
Fracking: the good, the bad and the ugly
(11/18/2013) The last few years have ushered in a new national and global awareness of fracking, the 150-year-old technology for extracting natural gas and oil from rock. Fracking, short for hydraulic fracturing, uses ultra-high-pressure slurries to create hairline fractures throughout solid rock. Oil, and more frequently gas, comes rushing out while sand from the mixture holds the fractures open in this nearly alchemical process. As many readers are aware, there are two very divisive schools of thought on fracking. One side touts it as the future of energy. The other derides fracking as inherently toxic and demands its immediate and permanent cessation. Like so many aspects of life, the truth lies somewhere in between.
Coal's future carbon costs may make it more expensive than wind energy
(11/15/2013) At first glance, a recent report from the U.S. White House on the social cost of carbon reads like a daunting economics exam. A small chart poses the first question about the price tag policymakers attach to future greenhouse gas emissions: Does each metric ton of carbon that billows into the air cost $11, $33 or $52? The answer is all of the above.
Powered by Google, high resolution forest map reveals massive deforestation worldwide
(11/14/2013) Researchers today released a long-awaited tool that reveals the extent of forest cover loss and gain on a global scale. Powered by Google's massive computing cloud, the interactive forest map establishes a new baseline for measuring deforestation and forest recovery across all of the world's countries, biomes, and forest types. The map has far-reaching implications for efforts to slow deforestation, which accounts for roughly ten percent of greenhouse gas emissions produced by human activities, according to the authors of the paper that describes the tool and details its first findings.
Wolves boost food for Yellowstone’s threatened grizzlies
(11/13/2013) Wolves and grizzlies aren’t best buddies. Burly bears can barge in on a feasting pack, making off with the wolves’ fresh kill. Wolves have been known to dig into bear dens and snag a cub. But after gray wolves returned to Yellowstone National Park in 1995, grizzly bears ate more berries in the summer for a pre-hibernation nutritional boost, researchers reported Sept. 4 in the Journal of Animal Ecology
Richest countries spent $74 billion on fossil fuel subsidies in 2011, eclipsing climate finance by seven times
(11/13/2013) In 2011, the top 11 richest carbon emitters spent an estimated $74 billion on fossil fuel subsidies, or seven times the amount spent on fast-track climate financing to developing nations, according to a recent report by the Overseas Development Institute. Worldwide, nations spent over half a trillion dollars on fossil fuel subsidies in 2011 according to the International Energy Agency (IEA).
Bay Area pledges to slash greenhouse gas emissions by 80 percent by 2050
(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.
'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.
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.
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.
Scientists uncover high radioactivity near fracking site in Pennsylvania
(10/07/2013) Scientists have for the first time found dangerous levels of radioactivity and salinity at a shale gas waste disposal site that could contaminate drinking water. If the UK follows in the steps of the US "shale gas revolution", it should impose regulations to stop such radioactive buildup, they said.
4 new species of legless lizards discovered in California
(09/18/2013) Four previously unknown species of legless lizard have been described in California, report researchers from the University of California at Berkeley and Cal State-Fullerton.
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.
Not just bats and frogs: snake fungal disease hits U.S.
(09/06/2013) A fungal outbreak in the eastern and Midwestern United States is infecting some populations of wild snakes. Snake Fungal Disease (SFD), a fungal dermatitis consistently associated with the fungus Ophidiomyces ophiodiicola, is showing recent spikes in occurrence according to the U.S. Geological Survey's National Wildlife Health Center (NWHC) and other diagnostic laboratories.
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.
