Should zoos educate the public about climate change?

2013-06-18T17:37:00Z

Zoos are usually thought of as entertainment destinations. As a place to take the kids on a nice afternoon, they are sometimes perceived to lack the educational heft of an art museum or a theatre. However, over the past few decades many of the world's best zoos and aquariums have also worked to educate their visitors about conservation issues, in addition to funding and supporting programs in the field to save the ever-growing number of imperiled species. But as threats to the world's species mount—including climate change—many are beginning to ask what, if anything, zoos and aquariums should do to address the global environmental crisis.

New York City may mandate composting of food scraps to cut garbage bill

2013-06-18T12:38:00Z

The mayor of New York, Michael Bloomberg, is preparing to roll out a new composting plan for the city, aimed at diverting some of the 100,000 tons of food scraps that ends up in landfill every year.

Fertility in Africa could push world population over 11 billion

2013-06-13T18:31:00Z

The global population could grow by another 4 billion people by the end of the century if fertility rates in Africa don't decline, according to a new report by the United Nations. Currently around 1.1 billion people live on the continent, but that number could skyrocket to 4.2 billion (a 380 percent increase) by 2100, causing global population to hit 11 billion.

Bachmann was right? $2 gas, with a catch

2013-06-11T22:04:00Z

One of Republican House member Michele Bachmann's most famous and controversial campaign promises — that Americans would see $2-a-gallon gasoline prices if she were elected president — may have come true without her even winning the nomination. Only not in the way she expected.

Ocean acidification pushing young oysters into 'death race'

2013-06-11T18:08:00Z

Scientists have long known that ocean acidification is leading to a decline in Pacific oyster (Crassostrea gigas) in the U.S.'s Pacific Northwest region, but a new study in the American Geophysical Union shows exactly how the change is undercutting populations of these economically-important molluscs. Caused by carbon dioxide emissions, ocean acidification changes the very chemistry of marine waters by lowering pH levels; this has a number consequences including decreasing the availability of calcium carbonate, which oysters and other molluscs use to build shells.

U.S. govt has role to play in stopping commodity-driven deforestation

2013-06-07T18:58:00Z

Southern U.S. logging soars to meet foreign biofuel demand

2013-06-06T18:12:00Z

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

2013-06-04T17:51:00Z

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.

Canadian government drops over $16 million on advertising its tar sands

2013-05-16T15:33:00Z

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.

Industrialized fishing has forced seabirds to change what they eat

2013-05-14T19:30:00Z

The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.

Featured video: saving sea turtles in Mexico's Magdalena Bay

2013-05-09T14:42:00Z

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

2013-05-09T12:53:00Z

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.

Uranium mine at edge of Grand Canyon National Park approved

2013-05-08T14:53:00Z

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.

Frankenfish or scientific marvel?: giant GM salmon await U.S. approval

2013-05-07T15:15:00Z

It is hard to think of a more unlikely setting for genetic experimentation or for raising salmon: a rundown shed at a secretive location in the Panamanian rainforest miles inland and 1,500m above sea level. But the facility, which is owned by an American company AquaBounty Technologies, stands on the verge of delivering the first genetically modified food animal—a fast-growing salmon—to supermarkets and dinner tables.

The Hawaiian silversword: another warning on climate change

2013-05-06T21:28:00Z

The Hawaiian silversword (Argyroxyphium sandwicense), a beautiful, spiny plant from the volcanic Hawaiian highlands may not survive the ravages of climate change, according to a new study in Global Change Biology.

Ten U.S. cities pledge to kick fossil fuel investments to the curb

2013-05-01T13:32:00Z

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

2013-04-30T21:49:00Z

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

2013-04-29T17:56:00Z

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.

With addition of smog, trees may generate air pollution

2013-04-26T19:32:00Z

In 2004 scientists found that isoprene, a compound produced by trees to protect their leaves from oxidation and temperature fluctuations, plays a role in the production of particulate matter, tiny particles that can cause lung damage, asthma, and other health problems. The finding — which led some to argue that forests are worsening air pollution rather than helping mitigate it — was incomplete however. Researchers didn't fully understand how isoprene and air pollution was linked.

Despite unseasonable cold in EU and U.S., March was tenth warmest on record

2013-04-22T12:34:00Z

While the month of March saw colder-than-average temperatures across a wide-swath of the northern hemisphere—including the U.S., southern Canada, Europe, and northern Asia—globally, it was the tenth warmest March on record in the last 134 years, putting it in the top 7 percent.

How many animals do we need to keep extinction at bay?

2013-04-15T16:32:00Z

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

2013-04-10T19:44:00Z

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.

Norwegian Pinot Noir?: global warming to drastically shift wine regions

2013-04-08T16:04:00Z

In less than 40 years, drinking wine could have a major toll on the environment and wildlife, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). The study finds that climate change will likely force many vineyards to move either north or to higher altitudes, leading to habitat loss, biodiversity declines, and increased pressure for freshwater. Some famous wine-growing areas could be lost, including in the Mediterranean, while development of new wine areas—such as those in the Rocky Mountains and northern Europe—could lead to what the the scientists describe as "conservation conflicts."

U.S. CO2 emissions fall to lowest level since 1994

2013-04-05T17:00:00Z

Carbon dioxide emissions from energy consumption in the United States during 2012 fell to the lowest level since 1994, finds a new report from the U.S. Energy Information Administration, a branch of the Department of Energy.

Greener neighborhoods have less violent crime

2013-04-04T19:41:00Z

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)

2013-04-04T18:10:00Z

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

2013-04-03T15:38:00Z

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.

U.S. book industry using 24 percent recycled paper on average

2013-04-01T16:27:00Z

From 2004 to 2010, book publishers increased their use of recycled fiber by nearly five times, from 5 percent to 24 percent on average, according to a new report by the Book Industry Environmental Council (BIEC) and Green Press Initiative. The report, which depends on voluntary statistics from the book industry, also found that nearly all (89 percent) of book publishers have environmental policies.

Is hemp the silver bullet for fighting climate change and creating green jobs?

2013-03-30T19:50:00Z

Though Obama has frequently spoken of the need for more “green jobs,” he has failed to acknowledge the inherent environmental advantages associated with a curious plant called hemp. One of the earliest domesticated crops, hemp is incredibly versatile and can be utilized for everything from food, clothing, rope, paper and plastic to even car parts. In an era of high unemployment, hemp could provide welcome relief to the states and help to spur the transition from antiquated and polluting manufacturing jobs to the new green economy. What is more, in lieu of our warming world and climate change, the need for environmentally sustainable industries like hemp has never been greater. Given all of these benefits, why have Obama and the political establishment chosen to remain silent?

Common pesticides disrupt brain functioning in bees

2013-03-27T16:47:00Z

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).

U.S. Admiral: climate change, not North Korea, biggest threat in the Pacific

2013-03-13T16:59:00Z

This week, Admiral Samuel J. Locklear II, the head of U.S. military forces in the Pacific, told The Boston Globe that climate change was the gravest threat in the region. While such an assessment may be surprising, given North Korea's recent nuclear tests, the U.S. military has long viewed climate change as a massive destabilizing force on global security.

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.

Shell suspends Arctic oil drilling for the year

2013-02-27T22:38:00Z

Royal Dutch Shell announced today that it was setting "pause" on its exploratory drilling activities in the Arctic for 2013. Shell's operations are currently under review by the federal government after the oil company suffered numerous setbacks during last year's opening attempt to drill exploratory wells in the Beaufort and Chukchi Seas, including running its drilling rig aground on Sitkalidak Island in southern Alaska in late December.

First strike: nearly 200 illegal loggers arrested in massive sting across 12 countries

2013-02-20T18:09:00Z

One-hundred-and-ninety-seven illegal loggers across a dozen Central and South American countries have been arrested during INTERPOL's first strike against widespread forestry crime. INTERPOL, or The International Criminal Police Organization, worked with local police forces to take a first crack at illegal logging. In all the effort, known as Operation Lead, resulted in the seizure of 50,000 cubic meters of wood worth around $8 million.

Over 35,000 march on Washington demanding climate action and rejection of Canada's 'carbon bomb'

2013-02-18T17:23:00Z

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

2013-02-13T20:56:00Z

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

2013-02-13T19:16:00Z

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.

Chasing down 'quest species': new book travels the world in search of rarity in nature

2013-02-13T15:50:00Z

In his new book, The Kingdom of Rarities, Eric Dinerstein chases after rare animals around the world, from the maned wolf (Chrysocyon brachyurus) in Brazil to the golden langur (Trachypithecus geei) in Bhutan to Kirtland's warbler (Setophaga kirtlandii) in the forests of Michigan. Throughout his journeys, he tackles the concept of rarity in nature head-on. Contrary to popular belief, rarity is actually the norm in the wildlife world.

Over 1,500 wolves killed in the contiguous U.S. since hunting legalized

2013-02-06T17:28:00Z

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

2013-02-05T22:19:00Z

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.

Killer kittens: U.S. cats kill up to 25 billion birds and small mammals per year

Global warming - 56 million years ago

2013-01-23T16:09:00Z

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.
