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.
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.
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.
Losing just one pollinator species leads to big plant declines
(07/22/2013) A shocking new study finds that losing just one pollinator species could lead to major declines in plant productivity, a finding that has broad implications for biodiversity conservation. Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are in major trouble as they are hit by habitat loss, pesticides, disease and other impacts. In fact, the EU has recently banned several pesticides that have been linked to the global bee decline.
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.
Featured video: saving animals from the illegal pet trade in Guatemala
(07/22/2013) Found in Central America's largest forest, the Maya Biosphere Reserve, the Guatemalan organization Arcas has rescued and rehabilitated thousands of animals since its inception in 1989. Unlike many wildlife rescue centers worldwide, Arcas focuses on rehabilitating every animal for eventually release back into the wild. This means intensive training for each species, including food gathering and predator avoidance. A new short video by Arcas highlights the group's decades-long work.
Featured video: mangroves in El Salvador imperiled by climate change
(07/17/2013) A new short video by Friends of the Earth International highlights the impacts of climate change on mangroves in El Salvador, which local fishermen depend on for their livelihoods.
The Warbler Guide - book review
(07/15/2013) Written by Tom Stephenson and Scott Whittle, with illustrations by Catherine Hamilton, The Warbler Guide by Princeton University Press is the "go-to" guide for identifying the 56 species of warblers in the United States and Canada. Warblers are notoriously difficult to identify. These champion singers are small, hidden amongst the tree top canopy, flighty and dancing from branch to branch, with variegated coloring blending greens, yellows, reds, browns, and grays.
Obama to take on elephant and rhino poaching in Africa
(07/03/2013) Barack Obama launched a new initiative against wildlife trafficking on Monday, using his executive authority to take action against an illegal trade that is fueling rebel wars and now threatens the survival of elephants and rhinoceroses. The initiative, announced as the president visited Tanzania on the final stop of his African tour, was the second time in a week Obama has used an executive order to advance environmental policy, after announcing a sweeping new climate change plan.
San Francisco seafood restaurants go sustainable
(07/02/2013) The Seafood Watch Program, first created by Monterey Bay Aquarium in the late 1990s, is arguably the best-known guide to sustainably-caught seafood in the U.S. Listing seafood choices in three categories—green (best choices), yellow (good alternatives), and red (avoid)—the guide informs consumers of the best options. However, it's one thing to create a well-respected guide, and another issues altogether to get producers and consumers to use it. But a newer partnership, the San Francisco Seafood Watch Alliance, is working to bridge this gap. Maggie Ostdahl of Aquarium of the Bay works with the Seafood Watch Restaurant program and restaurants across San Francisco—one of the best places in the country for seafood—to source sustainable seafood. Restaurant partners avoid seafood on the guide's red list.
Activists, indigenous people plan healing walk in 'sick' tar sands landscape
(07/01/2013) Hundreds of activists including Bill McKibben and Naomi Klein are going into the heart of Canada's tar sands this week – not to protest the destruction of the local environment, but to pray for the 'healing' of land and the people. Native elders from all over North America will lead people past lakes of tailings wastewater and massive infrastructure of the tar sands industry along the Athabasca River in Fort McMurray, Alberta.
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.
NASA image shows nearly ice-free Alaska as temps top 96 degrees
(06/24/2013) After a colder-than-average spring, Alaska is suffering a sudden and record-breaking heatwave. Temperatures on Monday, June 17th hit a stunning 96 degrees Fahrenheit (35 degrees Celsius) in Talkeetna, Alaska, just below the state's highest temperature ever record of 98 degrees Fahrenheit in 1969. On the same day, NASA's Terra Satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) took a rare image of a cloud-free Alaska.
Flying rainbows: the scarlet macaw returns to Mexico
(06/11/2013) On April 21, 2013, the first flock of scarlet macaws (of many more to come) was released into the jungles of Aluxes Ecopark, nearby classified World Heritage Site Palenque National Park, as a part of a massive reintroduction project to restore the popular and culturally-significant bird to the well preserved rainforests of Palenque and the rest of its southern Mexico homeland—where the species has been extinct for close to 70 years.
Southern U.S. logging soars to meet foreign biofuel demand
(06/06/2013) In order to meet the European Union's goal of 20% renewables by 2020, some European utility companies are moving away from coal and replacing it with wood pellet fuel. The idea is simple: trees will regrow and recapture the carbon released in the burning of wood pellets, making the process supposedly carbon-neutral. But just like other simple ideas, it misses out important details that can turn it on its head.
Canadian province cancels tar sands pipeline due to environmental impact
(06/04/2013) Efforts to expand production from the Alberta tar sands suffered a significant setback on Friday when the provincial government of British Columbia rejected a pipeline project because of environmental shortcomings. In a strongly worded statement, the government of the province said it was not satisfied with the pipeline company's oil spill response plans.
Plants re-grow after five centuries under the ice
(05/27/2013) While monitoring the retreat of the Teardrop Glacier in the Canadian Arctic, scientists have found that recently unfrozen plants, some of which had been under ice since the reign of Henry VIII, were capable of new growth.
New prehistoric animal named after Johnny Depp due to its 'scissorhands'
(05/19/2013) Half a billion years after an arthropod with long triple claws roamed the shallow Cambrian seas, scientists have named it after Hollywood movie actor, Johnny Depp: Kooteninchela deppi. Depp, known for his versatility as an actor, played Edward Scissorhands—an artificial man with long scissors for hands—in a popular 1990 film.
Canadian government drops over $16 million on advertising its tar sands
(05/16/2013) The Canadian government has nearly doubled its advertising spending to promote the Alberta tar sands in an aggressive new lobbying push ahead of Thursday's visit to New York by the prime minister, Stephen Harper. The Harper government has increased its advertising spending on the Alberta tar sands to $16.5m from $9m a year ago.
Common moth can hear higher frequencies than any other animal on Earth
(05/09/2013) A common little moth turns out to have the best ears in the animal kingdom. According to a new study in Biology Letters, the greater wax moth (Galleria mellonella) is capable of hearing frequencies up to 300,000 hertz (300kHz), which is 15 times the frequency humans can hear at their prime, around 20 kHz.
Featured video: saving sea turtles in Mexico's Magdalena Bay
(05/09/2013) A new short film, Viva la tortuga documents the struggle to save loggerhead and green sea turtles in Magdalena Bay, Mexico. Once a region for a massive sea turtle meat market, the turtles now face a new threat: bycatch. Loggerhead sea turtles are drowning in bottom-set gillnets, unable to escape from the nets once entangled. The issue has even raises threats of trade embargoes from the U.S.
U.S. loses nearly a third of its honey bees this season
(05/09/2013) Nearly a third of managed honeybee colonies in America died out or disappeared over the winter, an annual survey found on Wednesday. The decline—which was far worse than the winter before—threatens the survival of some bee colonies. The heavy losses of pollinators also threatens the country's food supply, researchers said. The US Department of Agriculture has estimated that honeybees contribute some $20bn to the economy every year.
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.
Uranium mine at edge of Grand Canyon National Park approved
(05/08/2013) Uranium mining on the doorstep of the Grand Canyon national park is set to go ahead in 2015 despite a ban imposed last year by Barack Obama. Energy Fuels Resources has been given federal approval to reopen its old Canyon Mine, located six miles south of the canyon's popular South Rim entrance, that attracts nearly 5 million visitors a year.
Ten U.S. cities pledge to kick fossil fuel investments to the curb
(05/01/2013) The cities of San Francisco and Seattle have pulled their money out of fossil fuel companies, taking a climate divestment campaign from college campuses to local government. The campaign group 350.org said on Thursday it had won commitments from a total of 10 cities and towns to divest from 200 of leading fossil fuel companies.
Citizen group finds 30 toxic chemicals in air following tar sands oil spill in Arkansas
(04/30/2013) Independent air samples by locals have yielded "a soup of toxic chemicals" in Mayflower, Arkansas where an Exxon Mobil pipeline burst on March 29th spilling some 5,000 barrels of tar sands oil, known as bitumen. Chemicals detected included several linked to cancer, reproductive problems, and neurological impacts such as benzene and ethylbenzene. Air samples were taken by community leader and University of Central Arkansas student April Lane a day after the spill. However, the Environment Protection Agency (EPA)'s and Exxon Mobil's air samples have yielded chemical levels below harm except in the direct clean-up area, according to the Arkansas Department of Health (ADH).
Obama Administration to propose stripping protection from all gray wolves
(04/29/2013) The U.S. Fish and Wildlife Service (USFWS) is proposing to end protection for all gray wolves (Canis lupus) in the lower 48 states, save for a small population of Mexican wolves in New Mexico, reports the Los Angeles Times. The proposal comes two years after wolves were removed from the Endangered Species Act (ESA) in western states by a legislative rider on a budget bill, and soon after in the midwest. Since then hunting and trapping has killed over 1,500 wolves in these two regions.
The Crossley ID Guide: Raptors - book review
(04/22/2013) Richard Crossley, Jerry Liguori, and Brian Sullivan have produced a unique and much needed bird book in The Crossley ID Guide: Raptors. The Crossley ID Guide: Raptors is a book you study at home so you can easily recognize North American raptors.
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.
How many animals do we need to keep extinction at bay?
(04/15/2013) How many animal individuals are needed to ensure a species isn't doomed to extinction even with our best conservation efforts? While no one knows exactly, scientists have created complex models to attempt an answer. They call this important threshold the "minimum viable population" and have spilled plenty of ink trying to decipher estimates, many of which fall in the thousands. However, a new study in Conservation Biology shows that some long-lived animals may not need so many individuals to retain a stable population.
International Paper commits to working with longtime foe to protect endangered forests
(04/10/2013) In another sign that the global paper industry may be steering toward more sustainable practices following years of bruising activist campaigns and pressure from buyers, International Paper (IP) has committed to identifying and protecting endangered forests and high conservation value areas in the southern U.S. The company, which is the world's largest paper maker, will be partnering with its tenacious NGO critic, the Dogwood Alliance, in order to map out forests in the region and, furthermore, move away from converting natural forests into pine plantations.
Greener neighborhoods have less violent crime
(04/04/2013) Turn your neighborhood green and it may prevent violent crime in the long run, according to a new study in Landscape and Urban Planning, which found that violent crimes (assaults, robberies, and burglaries) occurred less often in greener areas of Philadelphia. The connection between greener neighborhoods and less violent crime even stood up after researchers accounted for education, poverty, and population levels.
Tar sands oil spill: ruptured pipe pours 200,000 gallons of oil into suburban neighborhood (photos)
(04/04/2013) Last Saturday, an oil pipeline carrying tar sands oil from Canada ruptured in Mayflower, Arkansas spilling between 3,500-5,000 barrels of crude (at most 210,000 gallons) into neighborhood streets and lawns. Families from 22 homes have been evacuated while clean-up crews have scrambled to contain the spill. ExxonMobil, which runs the 65-year-old Pegasus pipeline, has stated it will pay for any damage, however critics say the oil spill is more evidence that the Obama Administration should turn down the Keystone XL tar sands pipeline.
U.S. Republican voters want action on climate change
(04/03/2013) A new poll by the Center for Climate Change Communication (4C) at George Mason University finds that a majority of U.S. citizens who identify as Republicans or Republican-leaning independents want the government to do more to tackles climate change. Sixty-two percent of those polled said that the U.S. government "absolutely should" or "probably should" takes steps to address climate change. This goes against the views of many Republican congressmen—as well as the party platform—who largely oppose action on climate change.
Common pesticides disrupt brain functioning in bees
(03/27/2013) Exposure to commonly used pesticides directly disrupts brain functioning in bees, according to new research in Nature. While the study is the first to record that popular pesticides directly injure bee brain physiology, it adds to a slew of recent studies showing that pesticides, especially neonicotinoids, are capable of devastating bee hives and may be, at least, partly responsible for on-going Colony Collapse Disorder (CCD).
Solar Photovoltaic Projects: In the Mainstream Power Market - book review
(03/11/2013) Solar Photovoltaic Projects: In the Mainstream Power Market, written by renewables energy pioneer Philip Wolfe, is an excellent introduction to the solar photovoltaic project development and power markets sector.
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.
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.
Genetics study claims to prove existence of Bigfoot
(02/13/2013) A new study purporting to uncover DNA evidence for Bigfoot has been published today in DeNovo Scientific Journal. While Bigfoot-enthusiasts have long argued that the cryptic monster is an unidentified ape species, the new study says their genetic evidence shows the Sasquatch is in fact a hybrid of modern human females mating with an unidentified primate species 13,000 years ago. The only problem: the journal in which the study is published—DeNovo Scientific Journal—appears to have been created recently with the sole purpose to publish this study.
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.
Over 1,500 wolves killed in the contiguous U.S. since hunting legalized
(02/06/2013) Hunters and trappers have killed approximately 1,530 wolves over the last 18 months in the contiguous U.S., which excludes Alaska. After being protected under the Endangered Species Act (ESA) for 38 years, gray wolves (Canis lupus) were stripped of their protected states in 2011 by a legislative rider (the only animal to ever be removed in this way). Hunting and trapping first began in Montana and Idaho and has since opened in Wyoming, Minnesota, and Wisconsin.
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.
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.
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.
Fish unable to pass through dams in U.S. presents 'cautionary tale' for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a "cautionary tale" for developing nations.
Presence of trees may mitigate cardiovascular and respiratory disease
(01/17/2013) Scientists with the U.S. Forest Service have observed a link between human health and trees, implying that trees may actually mitigate both cardiovascular and lower respiratory disease. Although the researchers do not yet put forward a reason why or how the presence of trees save lives, they are convinced there is a link.
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.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
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).
