Northeast Greenland Glaciers
Are Now Melting Rapidly, Study Finds
The glaciers of northeast Greenland, long thought to be the most stable part of the massive Greenland ice sheet, are melting at an accelerating pace, losing roughly 10
billion tons of ice annually for the past decade, say researchers
from the U.S. and Denmark. The finding will likely boost estimates of global sea level rise, which had previously not accounted for massive ice loss from that region, scientists say. The Zachariae ice stream in northeast Greenland, which drains 16 percent of the ice sheet, has retreated roughly 12.4 miles in the past decade, outpacing the fast-moving Jakobshavn glacier, which has retreated 21.7 miles over the last 150 years. Ice loss from the region is likely accelerating, the researchers say, because ice dams in nearby bays that had been blocking the glaciers' paths are now also melting, freeing the way for the glaciers to flow into the ocean.

Major Winds Have Lashed
North Atlantic This Winter, NOAA Map Shows
Forty-three hurricane-force winter storms have lashed the North Atlantic since late October, boosting the region's average wind speed in January and February by more than 12 miles per hour, as shown in this map
the U.S. National Oceanic and Atmospheric Administration (NOAA). The blue colors indicate areas where wind speeds exceeded the 1981-2010 average; browns indicate winds that were lower than average. In the North Atlantic, an unusually high number of hurricane-force storms, with winds exceeding 74 mph, battered southeastern Greenland, Norway, and the coast of western Europe. The U.K. Met Office recently issued a report on the December and January storms that ravaged the British coast, saying
, "For England and Wales this was one of, if not the most, exceptional (two month) periods of winter rainfall in at least 248 years." No studies have confirmed a link between these intense winter storms and climate change, but some scientists think climate-driven changes in the jet stream
may be behind the wild weather.

Solar City Partnering With
Best Buy to Sell Residential Solar Leases
Solar City, a company that installs and leases solar panels to homeowners, is partnering
with big-box electronics seller Best Buy in hopes of boosting solar sales in California, Arizona, Hawaii, Oregon, and New
A Solar City residential installation in Hawaii
York. Solar City will station salespeople in 60 stores throughout those states to pitch the benefits of their 20-year solar contracts directly to consumers, and Best Buy will take a cut of the sales. Based on a homeowner's utility company and monthly electric bill, Solar City representatives will be able to quickly give potential customers an estimate of the costs and savings associated with a solar lease. Leasing enables a homeowner to avoid the large upfront costs associated with purchasing and installing solar panels by spreading those investments over a 20-year lease and locking in a set rate for electricity generated by the panels. Residential solar installations have accelerated in recent years due largely to the popularity of leasing programs, with 2013 showing the fastest growth ever.

Nine Chinese Cities Outpaced
Beijing in Air Pollution in 2013, Report Says
China's air pollution problems are more severe and widespread than previously thought, with nine cities experiencing more days of extreme air pollution than Beijing in 2013, according to
a new analysis by Greenpeace's Energy Desk. Fine particulate (PM2.5) pollution plagued dozens of cities and millions of people in China — most of them outside of Beijing, although the Chinese capital captured the most air pollution headlines last year. The city of Xingtai, southwest of the capital, fared worst, with 129 days of emergency air pollution — more than doubling Beijing's 60 days. More than half of the cities in the top 10 are in Hebei province south of Beijing, where many steel, cement, and coal-fired power plants are located. "There are now millions of Chinese people living in cities with air pollution above emergency levels for a third of the year, while other urban areas have gone a whole 12-month period with hardly any days of good-quality air," said a member of Greenpeace's East Asia climate and energy campaign. Beijing had only 13 days ranked as "good" on the U.S. air quality scale, along with one day considered "beyond index," or off the pollution scale.

'Space Frame' Wind Tower
Allows Turbines to Be Built in Remote Places
New wind power technology could bring turbines to hard-to-reach locations, according to engineers from General Electric
. The company has developed a new
type of wind tower, dubbed the "Space Frame Tower," consisting of metal latticework wrapped in weather-resistant fiberglass. Unlike conventional steel tube wind towers, the latticework can be bolted together on-site, which means the tower's framework can be transported using standard shipping containers and trucks, allowing taller wind towers to be installed in locations previously inaccessible to the longer trucks needed to transport conventional towers. The Space Frame Tower also has a five-leg base that's wider than conventional towers, increasing stability and ultimately allowing it to reach heights up to 450 feet — an advantage at sites where higher turbines can reach stronger winds. A 318-foot tall prototype is up and running in Tehachapi, California, with a 2.75 megawatt turbine nearly 400 feet wide.

Arsenic Remediation Project
Will Begin Decontaminating Water in India
New technology that removes arsenic from drinking water is set to be deployed on a large scale in India, according to
researchers from Lawrence Berkeley National Laboratory and an India-based water technology company. The device removes arsenic by passing electricity through steel plates submerged in a water reservoir. The electric current causes the plates to rust more quickly than they would under normal conditions, and the rust chemically binds to arsenic in the water and sinks to the bottom of the reservoir. The precipitated sludge can be removed from the tank, rendering the water safe to drink. Notoriously high levels of arsenic, a tasteless and odorless contaminant, naturally occur in groundwater sources in India, Bangladesh, and even California's Central Valley. Long-term exposure can cause cancer and severe damage to organs. A commercial plant is set to begin operations in West Bengal, India, this year and researchers estimate the drinking water can be sold for as little as eight cents per gallon.

U.S. Car-Sharing Programs Have
Taken 500,000 Cars off Roads, Report Says
The rapid growth of car-sharing programs has cut the number of vehicles on U.S. roads by more than half a million, according to new research
by AlixPartners, a consultancy group with clients in the automotive industry. The trend will continue beyond 2020, the group projects, at which point 4 million people will be participating in car-sharing programs and 1.2 million fewer cars will be on the road. Of the 10 cities surveyed, residents of Boston, home of the Zipcar company, were most aware of car-sharing programs. Young people and, surprisingly, households with children were least likely to own their own cars, the survey said. Roughly half of the people who had tried car-sharing had already decided not to purchase or lease their own car, and did not plan to do so in the future. Rather than environmental concerns, nearly 60 percent of interviewees said cost and convenience led them to participate in car-sharing.

Warm River Water Plays Major
Role in Arctic Sea Ice Melt, Study Finds
Relatively warm water flowing into the Arctic Ocean from rivers contributes significantly to Arctic sea ice melt each summer, a phenomenon that will intensify as the region warms, according to NASA researchers
. The river discharge not only melts coastal sea ice, it also has
a wider climate impact as it creates more open water, which is darker than ice and absorbs more heat from sunlight. As these NASA images show, when water from Canada's Mackenzie River flowed into the Beaufort Sea in the summer of 2012, average surface temperature of the open water rose by 6.5 degrees C (11.7 degrees F) after the pulse of river water. Flow from the Mackenzie raised sea surface temperatures as far as 350 kilometers (217 miles) from the coast. The researchers note that river discharge is becoming an increasingly important contributor to melting Arctic sea ice because the volume and temperature of fresh water discharge is increasing as inland Arctic areas warm more each summer.
An e360 Interview with Wendell Berry:
Strong Voice for Local Farms and the Land

environmental movement. At age 79, Berry still speaks eloquently about the importance of local communities and of caring for the land, while warning about the destructive potential of industrialization and technology. In an interview with Yale Environment 360
, he talked about his Kentucky farm and why he has remained there, why sustainable agriculture faces an uphill battle, and why strong rural communities are important. “A deep familiarity between a local community and a local landscape is a dear thing, just in human terms,” Berry said. “It’s also, down the line, money in the bank, because it helps you to preserve the working capital of the place.”

Routes of Young Sea Turtles
Shed Light on Mystery of Turtles' Lost Years
By placing satellite tags on newborn sea turtles along the coast of Florida and tracking them in the western Atlantic Ocean, researchers have gained new insights
into the early migrations of threatened and endangered
turtles during their so-called "lost years" between hatching and returning to coastal waters as large juveniles. Rather than swimming in the currents of the North Atlantic gyre, as scientists had assumed, the young turtles actually leave the gyre and travel to the Sargasso Sea, which lies in the middle of the North Atlantic Ocean. While there, sensors on the turtles' shells registered more heat than the scientists expected, leading them to believe
that the young turtles swim near the surface of the Sargasso, basking in sunlight and feeding on a type of seaweed that grows in deep ocean waters. "From the time they leave our shores, we don't hear anything about them until they surface near the Canary Islands, which is like their primary school years," said an author of the study.

Atlanta Leads U.S. in
Electric Vehicle Sales Growth
Atlanta is the fastest growing market for electric cars in the U.S., according to an analysis
by the electric vehicle charging network ChargePoint. Electric vehicle (EV) sales in Atlanta jumped by 52 percent from the third quarter to the fourth quarter of 2013, with more than
3,000 EVs sold in the final three months of the year, according to state motor vehicle records. Washington, D.C., was the second-fastest growing market, with a 21 percent increase in sales, and Portland, Oregon, had the third-fastest growth, at 19.4 percent. While Los Angeles added the most EVs — more than 5,000 — to its streets, for a 19 percent growth rate, Atlanta outpaced it on a per capita and percent growth basis. Nationally, EV sales grew by nearly 450 percent
in the first three quarters of 2013 compared to the same period in 2012. ChargePoint's CEO speculated that popularity is increasing because charging station networks have expanded and EV designs have improved. "We’re well on our way to having twice the number of EVs on the road by the end of 2014," he said.

Harsh Winter Causing Large
Die-off of Invasive Insects, Researchers Say
As a frigid winter takes a toll on the United States and Canada, invasive insect populations are also taking a hit. The U.S. Forest Service estimates that up to 80 percent
of emerald ash borers, which have been decimating ash tree populations, were killed by long
Emerald ash borer
stretches of bitter cold in the the upper Midwest this year. Several other insect pests, many of which have migrated northward because of milder winters in recent years, also are faring poorly this winter, including corn earworms and gypsy moths. Researchers remain skeptical, however, that the die-offs will have lasting effects on pest populations. Emerald ash borers in Chicago, for example, survived the sub-zero weather because Chicago temperatures fell only to -17 degrees F, rather than Minnesota's -20 degrees F, which seems to be a critical temperature threshold for the pests.

Seafaring Drones Could Reveal
Mysterious Lives of Sharks, Researchers Say
New automated watercraft
are helping scientists understand the secret lives of great white sharks, which gather in large numbers each winter in an area nicknamed the "White Shark Cafe." Although this stretch of ocean between Baja California and Hawaii
contains relatively few food sources, the sharks congregate and display strange behaviors, perhaps related to mating or feeding, one researcher explained to the San Francisco Chronicle
. Scientists haven't had a way to efficiently track and observe sharks in this environment, but new seafaring drone technologies might change that. For example, drones could follow migrations by homing in on acoustic tags on the sharks themselves. Marine biologists at Stanford
were recently able to track two great whites on their journeys from California to Hawaii and the White Shark Cafe, as the map shows, but current technology only allows scientists to recreate the sharks' journeys after monitoring tags pop off and are recovered. The new drones may prove useful not only for tracking sharks and other pelagic fish in real time, but also for collecting important ocean data such as temperature, acidity, and salinity, researchers said.

Pine Forest Aerosols Play
Significant Role in Climate, Study Says
Pine forest vapors form small aerosol particles that may significantly cool the climate by reflecting the sun's energy back into space, according to new findings
. Scientists have known for decades that gases from pine
Hyytiälä pine forest in Finland
trees can form particles that grow from just 1 nanometer in diameter to 100 nanometers in about a day. The new research, published in Nature
, shows the rapid growth of these particles relies on a chemical chain reaction among pine-scented molecules and atmospheric ozone and oxygen. The growing particle then grabs others like it, eventually snowballing into a 100-nanometer particle — one that's large enough to condense water vapor, prompt cloud formation, and, ultimately, influence climate. Boreal or pine forests give off the largest amount of these compounds, so the finding is especially relevant for the northern parts of North America, Europe, and Russia. But other types of forests emit similar vapors, and the scientists think these may undergo similar rapid chemical reactions.

Large Offshore Wind Farms
Could Soften Blow of Hurricanes, Study Says
Offshore wind farms with thousands of wind turbines could have sapped much of the power of hurricanes Sandy, Katrina, and Isaac, significantly slowing their wind speeds, decreasing their accompanying storm surges, and possibly preventing billions of dollars in damages, according to a new study
. Computer models
used in the study said that deploying tens of thousands of offshore wind turbines could absorb enough energy from a hurricane to reduce peak wind speeds by 56 to 92 mph and storm surges by 6 to 79 percent. "We found that when wind turbines are present, they slow down the outer rotation winds of a hurricane," said Stanford engineer Mark Jacobson, who led the research. "This feeds back to decrease wave height ... which in turn slows the winds of the entire hurricane and dissipates it faster." For Hurricane Katrina, a massive turbine array could have slowed wind speeds by 58 percent and storm surge by 79 percent, and for Sandy wind speeds could have been cut by 14 percent and storm surge by 34 percent, according to findings published in Nature Climate Change

Massive Alaska Avalanche
Depicted in NASA Satellite Photograph
Southeastern Alaska recently experienced the largest landslide the planet has seen since 2010, and the aftermath is captured in this NASA satellite image
Triggered by the collapse of a near-vertical mountain face on the flanks of Mount La Perouse, 75 million tons of snow and sediment formed a debris flow nearly five miles long. The avalanche material appears light brown in contrast to the snow in the photo. Researchers at Columbia University first detected the event when seismic records from the region showed a large number of low-frequency waves; this satellite image and other aerial photos confirmed their hunch. The American Geophysical Union also posted this blog
featuring photographs from an Alaskan pilot who flew over the landslide.

Maps Show Extent of
Oil and Gas Drilling in Southwest Wyoming
Oil and gas wells, including those involved in hydraulic fracturing operations, scar a major portion of southwest Wyoming, according to a recent analysis by the U.S. Geological Survey
. Nearly 17,000 well pads and former
drilling areas associated with oil and natural gas production were identified in satellite images across a 30,000-square-mile region. The maps include well scars dating from around 1900, when oil drilling started in the region, up to 2009, at which point natural gas extraction far outweighed oil production. Since then, production has only intensified in Wyoming, a leading state in the U.S.'s unconventional oil and gas boom. The mapping effort, a first step in determining how oil and gas drilling operations impact wildlife and ecosystems, focused on southwestern Wyoming because it not only has some of the nation's largest natural gas reserves, but also because the region has high-quality wildlife habitat and encompasses a major portion of the country's remaining intact sagebrush steppe.

Rewritable Paper and Water Ink
Could Cut Paper Waste, Scientists Report
A new type of rewritable paper that uses water as ink could slash the amount of paper that's wasted daily, researchers say
. The paper contains hydrochromic dyes — chemicals that change color when wet — and a single
page can be reused dozens of times, the scientists report in Nature Communications
. Other types of rewritable papers have been developed, but they are all more expensive and energy-intensive to produce, and some versions use inks that pose environmental and safety hazards. The new system costs less than 1 percent of standard inkjet printing, the researchers estimate, primarily because ink cartridges are expensive. The researchers found they could refill cartridges with water and use them, along with the rewritable paper, in typical desktop printers. Print on the rewritable paper is only visible for about 22 hours, or as long as it takes the paper to dry completely. The scientists note that, while 90 percent of business information is retained on paper, most printed documents are read only once before being discarded.

Global Forest Watch Tool
Allows 'Near-Real Time' Forest Monitoring
A new online tool
called Global Forest Watch employs a trove of high-resolution NASA satellite imagery and large amounts of computing power to help governments, conservation organizations, and concerned citizens monitor deforestation in "near-real
time." Organized by the World Resources Institute (WRI), Global Forest Watch
uses satellite data to track changes in forest cover since 2000. It's the first tool with the capability of monitoring forests on a monthly basis, potentially allowing groups to take action against deforestation while it's in progress. Businesses committed to eliminating deforestation from supply chains can also use the tool to verify that vendors are not engaging in practices that harm forests. A custom alert feature can also notify a user when there are signs of deforestation in a region the user has selected. "Businesses, governments and communities desperately want better information about forests," said WRI president Andrew Steer. "Now, they have it."

Loss of Arctic Sea Ice
Has Greater Warming Impact Than Expected
The steady disappearance of Arctic sea ice, which is causing the exposed and darker surface of the Arctic Ocean to absorb more sunlight, is having a more profound impact on global warming
estimated, according to a new study. The decline of albedo, or reflectivity, from the Arctic Ocean equals roughly 25 percent of the warming caused by rising carbon dioxide levels, according to scientists at the University of California, San Diego. The impact of this "albedo feedback," in which the highly reflective white surface of sea ice is replaced by heat-absorbing open ocean, is considerably stronger than climate models had predicted, according to the UCSD research
, published in the Proceedings of the National Academy of Sciences.
Researchers had thought increasing Arctic cloud cover might slow the albedo feedback, but this study indicates that is not happening.

Website Allows Whistleblowers
To Report Wildlife and Forest Crimes
A new whistleblower site
offers people a secure and anonymous way to report incidents of poaching, wildlife trafficking, and illegal logging around the world. The site is called WildLeaks, a nod to the well-known WikiLeaks site, and it's backed by the California-based Elephant Action League. Users can upload documents, video, or images detailing the crimes, and submissions will be encrypted so data and identities remain secure. The aim
is to provide a safe way for citizens to report these illegal activities so that local and federal governments can take action. Prosecuting wildlife crimes and illegal logging is often a low priority in countries where some of the worst offenses occur; moreover, local government corruption often deters people from reporting such crimes, organizers say. "We [will] work to transform this information into a verified and actionable item, a point for launching an investigation or sharing it with the media or, when possible, with selected and trusted law enforcement officers, always aiming at exposing wildlife crimes and bringing the responsible individuals to justice," said the WildLeaks project leader.

New Maps Pinpointing Wind
Turbines Will Help Track Effects on Wildlife
More than 47,000 wind turbines dot the U.S. landscape, predominantly clustered in the Midwest and Great Plains, as a new interactive tool
developed by the U.S. Geological Survey (USGS) shows. The maps — the first
publicly-available, nationwide data set for wind energy generation — show the locations of every turbine in the U.S., from large wind farms to single turbines, and are accurate to within 10 meters. The maps are part of the USGS's effort to assess how wind turbines impact wildlife, and they show detailed technical information such as the make, model, height, area of the turbine blades, and capacity of each turbine. Turbine-level data will improve scientists’ ability to study wildlife collisions, the wakes causes by wind turbines, the interaction between wind turbines and ground-based radar, and how wind energy facilities overlap with migratory flyways, the USGS says.

Climate Benefits of Natural Gas
Are Questioned in A Major New Report
The U.S. Environmental Protection Agency has been underestimating methane leaks from natural gas production and use by 25 to 75 percent, according to a comprehensive assessment
of more than 200 studies. When the methane leaks are accounted for, natural gas contributes to climate change more than industry and the EPA have claimed, concludes the report by a team of U.S. scientists. In some cases, natural gas contributes to warming more than other fossil fuel sources. For instance, fueling trucks and buses with natural gas instead of diesel likely increases emissions, because diesel engines are relatively efficient, according to the researchers. Natural gas has been touted as an important "bridge fuel" because it emits less CO2 during combustion than oil and coal. Recently, though, studies have indicated that leaks of methane, a more potent greenhouse gas than CO2, during natural gas production, transportation, and consumption may offset its climate benefits. The new report, published in Science
, synthesized the results of 20 years' worth of methane leakage studies.

Australian Bushfire Has Grown
To Size of Melbourne, NASA Image Shows
A fire rivaling the size of the city of Melbourne is raging in southeastern Australia, as a NASA satellite image taken at night earlier this week shows. The Snowy River Complex Fire
, which is burning mountain forests near a
remote national park, is one of three bushfires that flared up last weekend. Fueled by strong winds combined with a heat wave and prolonged dry conditions, the three fires have consumed more than 180,000 hectares (695 square miles), about 100,000 (390 square miles) of which burned in the Snowy River Complex. That fire's dense, opaque smoke is visible from space during night and day, and satellite images show the smoke plume stretching across the Tasman Sea to New Zealand. The Snowy River blaze includes fires that ignited on February 9, as well as fires that were started by lightning in January. Though stunningly large in this view, they do not pose much of a threat to people or infrastructure.

Despite Costs, Most Americans
Want Action on Climate Change, Report Finds
A large majority of Americans — 83 percent — say the U.S. should make an effort to reduce global warming, even if those efforts have economic costs, according to a new report
from the Yale Project on Climate Change Communication. As many as 56 percent of Americans would be willing to pay an extra $100 each year if their power company would generate 20 percent of its electricity from renewable sources. Corporations and industry should be doing more to stave off climate change, according to 65 percent of people interviewed in a national survey, and 61 percent believe individual citizens should also be taking a more active role. Many of the survey's findings are similar across Democratic and Republican party lines. Tax rebates for energy-efficient vehicles and solar panels are popular among people aligned with both parties, for example, as well as funding renewable energy research and regulating carbon dioxide as a pollutant. And people from both parties are generally supportive of ending all fossil fuel subsidies, although Democrats (67 percent) are more supportive of that policy than Republicans (52 percent).

Shrinking Household Size
May Offset Progress in Curbing Population
Household size — the number of people living together under one roof — has been shrinking worldwide, and the trend could have major consequences for resource consumption
, new research finds
. Although global population growth has been somewhat curbed in the developed world, the number of households has continued to grow at a much faster pace in nearly all countries, Michigan State University researchers found. Average household size in developed nations declined from approximately five members in 1893 to 2.5 in 2000, while the rapid decline in household size in developing nations began around 1987, according to the research
, which analyzed trends between the years 1600 and 2000. Smaller households are typically less efficient, with fewer people using proportionally more land, water, and energy. Constructing housing units also consumes lumber and building supplies, and generally requires building more roads and commercial areas. "This will put enormous strain on the environmental life support system we rely on, even if we achieve a state of zero population growth," one study author said.

New Plant Found in Andes
Supports up to 50 Species, Researchers Say
Researchers working in the Ecuadorian Andes have discovered a new species of black pepper plant

Specialist herbivore Eios feeds on P. kelleyi
plant for survival. P. kelleyi
produces chemical compounds that are known to deter most herbivores, but a single type of caterpillar has adapted to overcome the toxicity of the plant's defenses. That caterpillar, in turn, is preyed upon by species of wasps and flies dependent on that specific caterpillar species — and ultimately the plant — for survival. Altogether, an assemblage of up to 50 species of herbivorous and predatory insects are dependent on P. kelleyi

Documented in Remote Forest in Congo

. The so-called "mega-culture," which spans 50,000 square kilometers of virtually untouched
Chimps are thriving in a remote Congo forest.
forest, is thought to be the largest population of chimps in Africa and one of the last remaining continuous populations of chimpanzees in the wild, the scientists report
in the journal Biological Conservation
. The researchers first reported on this community in 2007, but their new survey includes detailed videos of the thriving population and its unique behaviors, which include feasting on leopards, using tools to harvest giant African snails and swarming insects, and building ground nests far more frequently than other chimps. While the find is heartening in terms of chimpanzee conservation, the researchers and wildlife advocates fear the population could be decimated by habitat loss and poachers, who stand to make huge profits in the bushmeat trade.
