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.

Driven by State Incentives
Electric Cars Top Vehicle Sales in Norway
Norwegians have been snapping up electric cars: In the last three months of 2013, the Tesla Model S and Nissan Leaf outsold all other cars, including conventionally fueled models. But rather than environmental concerns,
An EV charges up in Oslo
a host of government incentives — totaling an estimated $8,300 per vehicle — are largely driving the boom, the Guardian reports
. Norway, a country of only 5 million people, currently has around 21,000 electric vehicles (EVs) on the roads, compared to 70,000 EVs among 313 million Americans and 5,000 EVs among 63 million people in the UK. More than 1,200 EVs are being sold in Norway per month thanks to incentives that include free electricity for recharging, lower sales tax rates, waived tolls, free parking, insurance discounts, and permission to drive in bus lanes, which are less crowded. The EV rush is expected to slow, however, as bus lanes become more crowded, and the government plans to end financial incentives once 50,000 EVs are registered, which could occur by 2016.
Interview: Activist Kumi Naidoo
On Russia and the Climate Struggle
Kumi Naidoo, the international executive director of Greenpeace, is intimately familiar with the Prirazlomnaya drilling platform in the Russian Arctic. In 2012, he and five other Greenpeace activists were hosed down with frigid water and pelted with pieces of metal as they attempted to climb aboard the platform.
Greenpeace and Prirazlomnaya were back in the news recently when 28 Greenpeace members were arrested and held for several months for storming the rig before being released in December. In an interview with Yale Environment 360
, Naidoo talks about what’s needed to get global climate talks off the ground and launch a green energy revolution, and the reason his activist organization has decided to take such a strong stand against oil drilling in the rapidly melting Arctic Ocean. "We went back [to Prirazlomnaya]," says Naidoo, "because we’re trying to draw a line in the ice, because once this starts it will have breached another threshold of meeting our rapacious appetite for oil and gas in the most fragile of environments."

Hydropower "Battery" Could
Even Out Wind Energy Supply, Scientists Say
Norwegian hydropower stations could be linked to wind farms
and serve as giant "batteries" to even out power supply fluctuations, a Scandinavian research organization says. A major hurdle for renewable energy suppliers is intermittent power production — sometimes too much power is generated, other times too little, and periods of peak demand often don't coincide with periods of peak supply. By using excess electricity from windy periods to pump water uphill into reservoirs, hydroelectric power stations could smooth out the intermittent power supplied by large wind farms, Scandinavian researchers from the firm SINTEF say. At times of low wind energy supply, the stored water could be released through dam turbines and hydroelectricity would fill the gap. The plan requires updating and refurbishing existing Norwegian hydropower plants, which could increase their output potential by 11 to 18 gigawatts, enough to provide an adequate backup power supply.

U.K. Government Pledges
To Stop Backing Foreign Coal Power Plants
The United Kingdom has joined the U.S. in pledging
to stop using government funds to finance coal-fired power plants in other countries. "The two governments are going to work together to secure the support of other countries ... and the multilateral development banks to adopt similar policies," Britain's energy secretary told journalists gathered in Warsaw at the U.N. climate talks. The U.S. made the same pledge last month in an attempt to slow CO2 emissions from the world's coal-fired power plants. The International Energy Agency reports that coal accounted for 44 percent of global carbon emissions in 2011, and the fossil fuel remains the world's largest source of electricity and heat. While many diplomats applaud the U.K.'s move, U.N. Secretary General Ban Ki-moon and environmental groups are pushing for even stronger action, including more spending on renewable energy. "The rapid development of low-carbon infrastructure needs large injections of public capital," Ki-moon said.

Underground Heat From
Cities Could Help Power Them, Study Says
The heat generated by urban areas and their buildings, factories, sewers, and transportation systems could be used to power those cities, according to a new study by German and Swiss researchers
. Thermal energy produced by the so-called "urban heat island effect" warms shallow aquifers lying below cities, and geothermal and groundwater heat pumps could tap into those warm reservoirs to heat and cool buildings, the scientists say. In the southwest German city of Karlsruhe, the researchers found that the city of 300,000 generated 1 petajoule of heat per year — enough to heat 18,000 households. Karlsruhe's underground heat production increased by about 10 percent over the past three decades, the team reported in Environmental Science and Technology
. The biggest contributors to the city's underground heat flux were its densely populated residential areas and surface temperature increases associated with paving. Sewage pipes, underground district heating networks, and thermal waste water discharges also contribute to warming shallow aquifers, the study found.

French Utility Company
Agrees to Build Major Nuclear Plant in U.K.
The British government and the French state-controlled utility company, EDF Group, have agreed to build the U.K.'s first nuclear power plant in a generation. The new plant, to be built at Hinkley Point in southwest England, is part of the British government's ongoing efforts to cut carbon emissions in half by the mid-2020s. To meet that goal, the U.K. plans to renew some of its existing nuclear plants and build several new plants to replace aging ones, the New York Times reports
. Once completed, the Hinkley Point nuclear power station will supply 7 percent of the country's electricity — enough to power 6 million homes. Consumers and taxpayers will cover most of the projected £16 ($26 billion) overall cost, but the proposed project is expected to face opposition since EDF will be guaranteed a price of roughly £90 ($145) per megawatt hour for 35 years, a rate that is considerably higher than current electricity costs.

Nine in 10 Europeans in Cities
Breathe Dangerous, Polluted Air, Study Says
More than 90 percent of Europeans living in cities are exposed to harmful levels of air pollutants, according to a new assessment
from the European Environment Agency. Concentrations of ground-level ozone, or smog,
pose a danger to 97 percent of city populations, and levels of fine particulate matter (particles with a diameter less than 2.5 microns, known as PM2.5) exceed European standards for 91 to 96 percent of city-dwellers — and European standards for both pollutants exceed World Health Organization
recommendations. A new study of European mothers linked higher PM2.5 exposure
to lower birth weight, a standard indicator of fetal development. Eastern European countries have the highest levels of PM2.5, whereas ground-level ozone is worst in northern Italy. Although emissions of most air pollutants have steadily declined over the past 10 years — lead and carbon monoxide levels, for example, now meet international standards in most areas — emissions haven't fallen as much as predicted.

Ikea to Sell Home Solar Panels
In All British Stores Within a Year
The Swedish furniture retailer Ikea will begin selling residential solar panels in its 17 UK stores within the next 10 months. The basic package's $9,500 price tag will include 18 panels, installation, maintenance,
design consultation, and energy monitoring. With energy savings and current green energy subsidies in the UK, consumers should typically earn as much as $1,244 per year and break even in about seven years, Ikea said. Great Britain's heavily subsidized green energy market is smaller than other European countries', but it has shown steady growth, rising 25 percent in the last year, the Guardian reports
. The decision by the world's largest furniture retailer comes after a successful test run at a store outside London, where solar panel sales averaged one unit per day. Ikea has not announced plans to sell units in the U.S., where some utility companies have sought an end to public subsidies of
residential solar installations.

Greenland Ice Hides Gorge
Longer than the Grand Canyon
A massive gorge nearly twice as long as the Grand Canyon is hidden under Greenland's ice sheet, reports a team of researchers from the U.K., Canada, and Italy.
With a width of about six miles and a maximum depth of 2,600 feet, the previously undiscovered canyon is as wide as its Arizona counterpart and nearly half as deep. Flowing water likely carved the canyon long before the formation of the mile-deep ice sheet that has blanketed it for the past few million years. Researchers found the feature using ice-penetrating radar equipment, they reported in Science
. The canyon does not yet have a name. "It's remarkable to find something like this when many people believe the surface of the earth is so well mapped," said lead author Jonathan Bamber, of the University of Bristol.

Ocean Acidification Could
Amplify Global Warming, Study Says
The increasing acidification of the world’s oceans caused by rising concentrations of atmospheric carbon dioxide not only poses a threat to marine creatures, but also could lead to an intensification of planetary warming,
according to a new study. A team of U.S., British, and German researchers conducted experiments in seawater enclosures, known as mesocosms
, showing that the increasing acidification of the ocean leads to a drop in production of an important sulfur compound, dimethylsulphide, or DMS. Marine emissions of DMS are the largest natural source of atmospheric sulfur,
and those sulfur aerosols play an important role in reflecting the sun’s energy back into space and cooling the planet. Reporting in the journal Nature Climate Change
, the scientists found that when they created acidic conditions in the seawater enclosures that match pH levels expected in 2100, emissions of DMS fell by roughly 18 percent. The scientists said their study was the first to prove the link between rising ocean acidification and the potential decrease in planet-cooling sulfur dioxide aerosols.

Too Many Urban Beehives
May Do More Harm Than Good, Experts Say
A surge in urban beekeeping may be doing more harm than good to honeybee populations
, according to UK scientists. As the number of rooftop hives increases in cities worldwide
— including London, where there are
A Berlin beekeeper
now 10 hives per square kilometer — two researchers from the University of Sussex warn that too many hives can be detrimental. Writing in The Biologist
, the magazine of the Society of Biology, they suggest that inexperienced beekeepers can create conditions in which there isn’t enough food for their insects. “If there are too many colonies in an area, then the food supply will be insufficient,” Francis Ratnieks, a professor at the university’s Laboratory of Apiculture and Social Insects, told the BBC. “This will mean that colonies do not thrive, and may also affect other species that also visit flowers.”

Whales Shown to Flee
From Mid-Frequency Military Sonar
Two new studies show that the use of military sonar can provoke whales to flee
, providing evidence that the naval operations may be a factor in mass strandings of whales and dolphins worldwide. According to one study
A blue whale
most marine mammal strandings related to naval sonar exercises involve beaked whales, a notoriously shy species that responds to noise levels well below those used by the U.S. Navy. Scientists believe the beaked whales may interpret the sonar noises as the sounds of killer whales. A separate study
found that even mid-frequency sonar affected the behavior of blue whales, the largest animals on earth, especially during feeding. After exposing tagged blue whales to simulated military sonar and other mid-frequency sounds, the animals often ceased feeding, increased swimming speeds, and traveled away from the sound. “Noise pollution threatens vulnerable populations, driving them away from areas important to their survival, and at worst injuring or even causing the deaths of some whales and dolphins,” Sarah Dolman of the non-profit group Whale and Dolphin Conservation told the Guardian

Desert Tree Plantings
Could Lower Atmospheric CO2 Levels
The large-scale planting of jatropha trees in the world’s arid regions could help reduce atmospheric levels of carbon dioxide
, a new study says. Using computer models and data from plantations in Egypt, India, and
Madagascar, a team of German scientists calculated that plantations of the durable, scrubby jatropha — which can also be used as a biofuel — could capture 17 to 25 tons of carbon dioxide per hectare annually. Jatropha is particularly suited for so-called “carbon farming” because it can grow in hot, dry regions where the soil is unsuitable for food crops, according to the study, published in the journal Earth System Dynamics
. In addition, the researchers estimate that there are about 1 billion hectares of “unused and marginal” land suitable for cultivating such tree plantations. Since jatropha trees do require some water, the authors suggest they should be planted near coastal regions where desalinated seawater could be accessible.

Wired Honeybees Show
Harmful Impacts of Pesticides on Navigation
Using tiny radar antennae glued to the backs of honeybees, European scientists have found that bees exposed to neonicotinoid pesticides were more likely to become disoriented
and separated from their hives.
Honeybee wired with radar antennae
After attaching the small transponders to 200 bees, including some that were fed pesticide-laced syrup, scientists discovered that the exposed bees had difficulty navigating and were unable to retrace the path back to their hives. “We find the control bees are just fantastic — they use their landscape and their vector memory and they do fine,” Randolf Menzel, an insect neurobiologist at the Free University in Berlin, told the London Telegraph
. “The treated bees, depending on the doses of the substance, are more confused.” The findings appear to support a theory that neonicotinoids make bees more vulnerable to pathogens and could be a factor in so-called “colony collapse disorder,” a phenomenon that has decimated honeybee populations
in recent years.

European Investment Bank
Will Not Finance Most Coal Power Stations
The European Investment Bank (EIB), the main lending arm of the European Union, has decided to stop financing most coal-fired power plants
, part of an effort to help the 28-nation bloc meet ambitious greenhouse gas reduction targets by 2030. The EIB says that new and refurbished coal-fired power stations will be ineligible for funding unless they emit less than 550 grams of carbon dioxide per kilowatt hour, a standard that traditional coal power plants would be unable to meet. Power stations that burn coal would only be able to meet the standards if they also produce heat for municipal or commercial heating systems or burned biomass. The EIB says it plans to further tighten its emissions standards for coal- and natural gas-fired power plants in the future.
Interview: Leaving Our Descendants
A Whopping Increase in Sea Levels
Last week, a group of scientists led by Anders Levermann of the Potsdam Institute for Climate Change Research released a paper
that made a stark forecast:
For every 1 degree Celsius of temperature increase, the world will eventually experience a 2.3-meter increase in sea level. That means that should carbon emissions continue to rise at or near current rates, and temperatures soar 4 to 5 degrees C in the next century or two, the world could well experience sea level increases of many meters — dozens of feet — in the centuries and millennia to come. In an interview with Yale Environment 360
, Levermann discusses how he and his colleagues reached their conclusions, how much disruption such large sea level increases might cause, and why we need to ponder the effect of our actions on future generations. “Society needs to decide about how much damage it wants to do in the future and how much damage future generations can actually cope with,” he says.

European Fish Stocks
Show Signs of Recovery, Study Says
A major assessment of fish stocks in the northeast Atlantic Ocean shows that many species are recovering and are now being fished sustainably.
The surprising findings, reported in the journal Current Biology,
are based on data from government research institutes that collected millions of measurements of fish, both at sea and in markets. The study showed that for the first time in decades the majority of fish stocks in the northeast Atlantic are recovering, thanks to reforms instituted by individual nations and the European Union in 2002. This good news comes amid widespread criticism of EU fisheries policies
, which recently have undergone further reform. “We should be aware that low fishing pressure needs to be maintained until stocks recover,” said researcher Robin Cook of the University of Strathclyde in Scotland. “This is only the first step. Now we need to see numbers increase as a result of continued low fishing pressure.”

fishing interests in the region, according to news reports. The plan, which was proposed by the U.S. and New Zealand, would have protected a total of 2.3 million square miles in the Ross Sea, a deep, high-latitude body of water in the Southern Ocean. But during a meeting of the 25-member Commission for Conservation of Antarctic Marine Living Resources, Russia questioned whether the organization had the legal right to create such a haven. A key sticking point for the Russians was the potential loss of the fishery for krill, a shrimp-like creature that is a critical food source for penguins, seabirds, seals, and whales, but is netted for use in Omega-3 dietary supplements.

Europe’s Offshore Wind Sector
Is Growing, But Troubles Lie Ahead
European nations installed a record number of offshore wind turbines
during the first half of 2013, adding more than twice the capacity installed during the same period in 2012, according to the European Wind Energy Association (EWEA), an industry group. A total of 277 new turbines in seven wind farms were fully connected to the grid during the six-month period, adding 1,045 megawatts of capacity, with another 130 turbines installed but awaiting connection, the group says in a new report
. Although the new turbines bumped Europe’s total offshore wind energy capacity to 6,040 megawatts, officials say the sector’s growth is already slowing as a result of regulatory uncertainty in key countries. While European nations such as Germany and the UK have relied on large-scale wind projects to achieve renewable energy targets by 2020, the lack of a binding target for 2030 will cause growth to stall, said Justin Wilkes, EWEA’s policy director. “Financing of new projects has slowed down with only one project reaching financial close so far this year,” he said.

Largest Offshore Wind Farm
Opened in North Sea Off British Coast
British Prime Minister David Cameron has inaugurated the world’s largest offshore wind farm
, a 630-megawatt project capable of producing enough electricity to power 500,000 homes. The $2.3 billion project — located 12 miles offshore in the North Sea, east of London — is being operated by an international consortium that includes China’s Dong Energy, German’s E.ON, and Abu Dhabi’s Masdar. The so-called London Array
project, which contains 175 turbines, began producing energy in April but was officially inaugurated yesterday by Cameron. The project’s opening solidifies the UK’s position as a global leader in offshore wind energy. The country currently produces 3 gigawatts of power from wind energy and by 2020 aims to develop 18 gigawatts, much of it from offshore wind power installations.

Bird-Mimicking Mobile Apps
Harmful to Species, UK Groups Say
Wildlife officials in the UK are urging people not to use mobile phone apps that mimic bird songs in nature reserves, warning that the devices can harm some sensitive species
, particularly during breeding season.

The increasingly popular apps, which use recordings of bird calls to lure the birds closer for photographs or better viewing, can distract birds from critical tasks, such as feeding their young, according to the Royal Society for the Protection of Birds. The Dorset Wildlife Trust (DWT), a conservation group that oversees 42 reserves, is discouraging the use of the mobile apps at its reserves
, calling it an intentional disturbance of sensitive species such as the Nightjar, a nocturnal bird that has experienced a recent recovery in the area. “I’m sure visitors would be devastated if they realized the possible disturbance they were causing to wildlife,” said Chris Thain, a manager at DWT’s Brownsea Island reserve.

Growing Number of Pests
Developing Resistance to GM Crops
An increasing number of pest species are developing resistance to crops genetically engineered to be toxic to insects
, according to new research. In an analysis of 77 studies conducted in eight countries, a team of U.S. and French scientists found that five of 13 major pest species had become resistant to so-called Bt cotton or corn plants, which are genetically modified to exude a bacterium, Bacillus thuringiensis
, that is toxic to insects. While researchers say all insects inevitably adapt to threats such as pesticides, the study found that farmers who planted non-Bt crops in nearby “refuges” were more likely to slow that resistance. “Either take more stringent measures to delay resistance, such as requiring larger refuges, or this pest will probably evolve resistance quickly,” said Bruce Tabashnik, a professor at the University of Arizona and lead author of the study published in the journal Nature Biotechnology
. The total land area planted annually with Bt crops has increased from 1.1 million hectares in 1996 to more than 66 million hectares in 2011.

Genetic Study Reveals Cheaper
Process to Convert Sawdust to Biofuel
A team of genetic engineers reports it has developed an inexpensive process that uses fungus to convert raw materials such as straw and sawdust into a productive biofuel
. While it was previously known that the Trichoderma
fungus produces the enzymes needed to break down such lignocellulosic wastes into a form of biofuel, the process was prohibitively expensive since the molecular switch required stimulation from a pure substance known as disaccharide sophorose, which is worth 60 times more than gold. Through genetic analysis, scientists from the Vienna University of Technology identified the specific gene that triggers the process — as well as the protein that the gene mutation affects — enabling them to mimic the same mutation in other strains of fungus. “We have understood the mechanism of this molecular switch and, consequently, many wonderful possibilities are opening up for us,” said Astrid Mach-Aigner, leader of the study published in the journal Biotechnology for Biofuels

Solar-Powered Airplane Finishes
First Leg of Coast-to-Coast U.S. Trip

aircraft, which runs on energy collected from 12,000 solar cells
View from the cockpit
in its long wings, flew from San Francisco to Phoenix in 18 hours and 18 minutes. The solar cells simultaneously power four batteries with the storage capacity of an electric car, which allows the plane to fly in darkness. The airplane, with a 208-foot wingspan, is made of lightweight, carbon fiber materials that help it conserve energy, but its spindly structure also makes the plane unable to fly in windy or stormy conditions. Project organizers hope the five-leg journey — which will include stops in Dallas, St. Louis, and Washington and end in New York — will demonstrate the feasibility of long-distance air travel without fuel. By 2015, the project's co-founders, Bertrand Piccard and Andre Borschberg, hope to complete a flight around the world.

Green Energy Investments
To Triple by 2030, Analysis Predicts
Annual investment in renewable energy is predicted to triple between now and 2030
, according to a report by Bloomberg New Energy Finance. In an analysis
of several factors shaping the global energy future —
First Solar Inc.
including economic conditions, market demands, and the evolution of technologies — the group predicted that annual spending may increase from $190 billion last year to $630 billion by 2030. A key factor in the growth is the plunging cost of wind and solar energy, which in the short term has bankrupted many manufacturers. The Bloomberg report also forecast significant growth in hydropower, geothermal, and biomass sources of energy. In the most likely scenario, 70 percent of new power generation capacity between 2012 and 2030 would come from renewable sources — with wind and solar accounting for 30 and 24 percent, respectively — while only 25 percent would come from fossil fuel sources.

Renewable Energy Generated
70 % Of Portugal’s Electricity in Quarter
Portugal generated more than 70 percent of its electricity
from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator. Hydroelectric generation provided 37 percent of the nation’s electricity from January to March, a 312-percent increase compared to last year, while wind energy accounted for 27 percent, a 60-percent increase, Redes Energéticas Nacionais (REN) reported
. While favorable weather helped drive the record levels in wind and hydroelectric power, the results also reflect Portugal’s investment in renewable energy projects
— including wind farms, hydroelectric, solar and wave energy — and an improved electricity grid that allows green energy providers to connect into the system. Nearly 45 percent of the country’s electricity will come from green sources this year compared with just 17 percent five years ago, ThinkProgress reports.

Marine Council's ‘Eco-Labeling’
Process Is Too Lenient, Report Says
The process by which the Marine Stewardship Council (MSC) certifies seafood as sustainable is too lenient and discretionary
, allowing for “overly generous interpretations” from third-party certifiers and adjudicators, a new report says. Launched in 1997, the UK-based MSC administers a well known eco-labeling process to inform consumers which fisheries are sustainable and provide incentives for better fisheries management. But in an analysis of 19 formal complaints against the council, a group of researchers found that several of the fisheries that received the MSC’s “sustainable” label — accounting for 35 percent of labeled seafood — apparently do not meet the council’s standards. For example, they found that Canada’s longline fishery for swordfish resulted in an extraordinary amount of incidental bycatch of other species, with the annual catch of 20,000 swordfish also netting 100,000 sharks, 1,200 endangered loggerhead turtles, and 170 leatherback turtles, according to the report, published in the journal Biological Conservation
