29 to 8.2 percent over the past decade, and the practice is gaining momentum under the guise of special infrastructure projects, according to information obtained
by the London-based advocacy group Environmental Investigation Agency (EIA). In 2013, Laos exported 1.8 million cubic yards of timber to Vietnam and China — more than 10 times the country’s official harvest, EIA found. Trade data also show that in 2014 China received $1 billion in illegal timber from Laos — a 22-fold increase from 2008. The high figures imply that the bulk of this timber is composed of valuable rosewood species, which are supposedly protected under Lao law. Virtually all logging operations are linked to infrastructure projects, especially hydropower dams, roads, mining, and agricultural plantations, EIA says.

The Hard-Working Beaver
Is A Fighter Against Nitrogen Pollution
As beaver populations rebound across North America, the ponds they create are proving to be an important factor in removing rapidly
growing levels of nitrogen

from waterways and estuaries, according to a new study. By creating ponds that slow down the movement of water, the beavers enable nitrogen — which comes from agricultural runoff, septic systems, and other human sources — to seep into soil, where much of it is broken down by bacteria. Reporting in the Journal of Environmental Quality
, researchers at the University of Rhode Island said that beaver ponds can remove up to 45 percent of nitrogen in the water. One scientist said that when they began to consider the widespread presence of beaver ponds, “we realized that the ponds can make a notable difference in the amount of nitrate that flows from our streams to our estuaries.”

Three-Fourths of Americans
Now Say that Climate Change is Occurring
It might be Pope Francis’ forceful stance on global warming, or increasing outbreaks of wild weather, droughts, and fires.
Americans who believe climate change is occurring
But whatever the cause, 76 percent of those polled in the U.S.
say that climate change is occurring, according to a poll from the University of Texas (UT). That is a 12-percent increase from March 2012, when only 65 percent of respondents said they believed in climate change. In that same period, the number of people saying that global warming is not occurring has fallen from 22 percent to 14 percent, according to the poll. All the recent publicity about climate change even seems to have been persuasive to Republicans, who traditionally have been more skeptical that climate change is taking place. The UT poll showed that the percentage of Republicans who say climate change is happening has risen from 47 percent in March of this year to 59 percent in September.

California Solar Development
Often Occurring On Wilderness Lands
More than half of the large solar energy installations that have been built or are planned in California are being
constructed on undeveloped lands

rather than in previously developed, less-sensitive areas, according to a new study. Researchers at the University of California, Berkeley, said that of 161 planned or operating utility-scale solar power developments in the state, more than 50 percent are being located on natural shrub or scrublands, such as the Mojave Desert. About 28 percent have been built on agricultural land and 16 percent have been built in developed areas, according to the study
, published in the Proceedings of the National Academy of Sciences. The researchers said that it makes far more sense for the state’s robust solar power industry
to locate its installations on farmland, especially considering the severity of California's ongoing drought.

permanent prohibition on cars in its downtown area. The newly elected city council announced that the city would also build at least 60 kilometers (37 miles) of new bike lanes by 2019 and provide a “massive boost” of investment in public transportation. Business owners in central Oslo fear that the car ban will reduce revenues, but leaders of the new council said the ban could even increase visitors to downtown and that the city would take steps to reduce negative impacts, including allowing vehicles to transport goods to stores and conducting trial runs of the ban to work out problems. Oslo, with 600,000 inhabitants and almost 350,000 cars, would be the first major European city with a permanent central car ban.

Oil and Coal Companies
Say They Back CO2 Cuts, Climate Talks
Ten major oil companies, mainly from Europe, on Friday acknowledged their industry’s role in climate change and said they agreed with United Nations goals to limit temperature increases
to 3.6 F. Their statement follows a similar declaration
on Wednesday by 14 major companies closely tied with the fossil fuel industry, including coal giants BHP Billiton and Rio Tinto, as well as Royal Dutch Shell, BP, and the world’s largest cement maker, LafargeHolcim. The Friday statement by European oil company executives acknowledged that the “existing trend of the world’s net global greenhouse gas emissions is not consistent” with UN climate targets. But the companies did not commit to specific production cuts or supporting a price on carbon. With UN climate talks opening in Paris in December, the statements by both groups are part of public relations efforts to demonstrate that oil and coal companies are willing to join in the fight to slow global warming.

Gates Calls Divestment
A `False Solution’ to Global Warming
Bill Gates, the founder of Microsoft and co-chair of the Bill and Melinda Gates Foundation, has called the fossil fuel divestment campaign a “false solution”
to climate change and says the best way to decarbonize the global economy is by developing revolutionary renewable energy technologies. “We need an energy miracle,” Gates told The Atlantic magazine.
“That may make it seem too daunting to people, but miracles in science are happening all the time.” Gates said he is pledging $2 billion of his foundation’s endowment to research and develop alternative energy technologies. He criticized the divestment movement
for “using up (campaigners’) idealism and energy on something that won’t emit less carbon.” The Gates Foundation, the world’s largest charitable organization, has $1.4 billion invested in fossil fuel companies, and activists have been calling on Gates to sell those holdings.

Toyota Vows to Eliminate
Nearly All of Its Gasoline Cars by 2050
The global automobile giant, Toyota, has announced plans to steadily phase out production of gasoline-powered cars
and to slash emissions from its fleet by 90 percent by 2050. Speaking in Tokyo, Toyota executives vowed to work with government officials and other companies to replace internal combustion cars with hydrogen fuel cell vehicles and hybrids. “You may think 35 years is a long time, but for an automaker to envision all combustion engines as gone is pretty extraordinary,” said a senior Toyota executive. The company said that by 2020 annual sales of its hybrid vehicles will reach 1.5 million and sales of fuel cell vehicles will hit 30,000 — 10 times the projected figure for 2017. Meanwhile, Volkswagen, shaken by scandal over falsifying emissions data on its diesel cars, announced it will increasingly shift production
to hybrid and electric vehicles.

Antarctic Ice Shelves Face
Major Threat If CO2 Emissions Keep Rising
A new study says that many of Antarctica’s floating ice shelves — which play a key role in holding back vast amounts of land-based ice — could become highly unstable
later this century if greenhouse gas emissions are not sharply reduced. An international team of researchers, reporting in Nature Geoscience
, said that surface melting of Antarctica’s ice shelves could reach the point where many could disintegrate. Such surface melting has already led to the collapse of numerous ice shelves along the rapidly warming Antarctic Peninsula. The study said that surface melting of the continent’s ice sheets would double by 2050
under both intermediate- and high-emissions scenarios. After that, the fate of the ice shelves diverges sharply depending on emissions levels, with a high-emissions scenario leading to surface melting equaling or exceeding intensities associated with ice shelf collapse. Loss of the ice shelves could lead to major increases in sea level as inland glaciers flow to the sea, scientists say.

New Head of IPCC
Calls For Shift from Science to Solutions
The new chairman of the Intergovernmental Panel on Climate Change says it’s time for the global scientific body to shift from documenting the impacts of climate change to finding solutions to global warming.
Hoesung Lee, a South Korean economist who was chosen by the IPCC last week to replace former chairman Rajendra Pachauri, told the Guardian that the window to begin slashing greenhouse gas emissions is “closing very rapidly” and said that the IPCC must help spur a move toward the widespread adoption of renewable energy technologies. He said that while the IPCC, which periodically issues voluminous scientific reports on climate change, had been doing a “fantastic job” of identifying the problem, “I believe the next cycle of the IPCC should be more focused on opportunities and solutions.” Lee said that placing a global price on carbon would be “the most important building block” for reducing CO2 emissions to zero by 2100.

‘Land Grabbing’ Is Accelerating
As Pressure on Agriculture Resources Grows
An area about the size of Japan — roughly 140,000 square miles — has been purchased or

leased by foreign entities for agricultural use during the last 15 years, according to a report
by the Worldwatch Institute. An additional 58,000 square miles are under negotiation, the report found. “Land grabbing,” a term for the purchase or lease of agricultural land by foreign interests, has emerged as a threat to food security in several nations. Globally, over half of this land is in Africa, especially in water-rich countries like the Congo. The largest area acquired in a single country is in Papua New Guinea, with nearly 15,500 square miles (over 8 percent of the nation’s total land cover) sold or leased to foreign entities. Foreign purchase of land in developing countries has surged since 2005 in response to rising food prices and growing biofuel demand in the U.S. and the European Union, as well as droughts in the U.S., Argentina, and Australia. “Essentially no additional suitable [agricultural] land remains in a belt around much of the middle of the planet,” writes Gary Gardner, a contributing author to the report.

Africa Can Increase Renewable
Energy Use Four-Fold by 2030, Study Finds
The African continent could generate nearly a quarter of its energy needs from renewable sources by 2030, according to a report
Solar PV minigrids serving 30 villages in Mali
by the International Renewable Energy Agency
(IRENA). The report identified potential renewable energy sources — including solar, biomass, hydropower, and wind resources — equivalent to more than 375 million tons of coal. While half of energy use in Africa today involves traditional biomass consumption, the report estimated that a shift to renewable-energy cooking solutions would reduce traditional cook stove usage and the resulting health complications from poor indoor air quality, leading to savings of $20 to 30 billion annually by 2030. In the African power sector, the share of renewable sources could increase to 50 percent by 2030, reducing carbon dioxide emissions by more than 340 million tons, the IRENA report says.

Styrofoam May Be Biodegradable
After All, Thanks to Mealworms, Study Says
Mealworms can survive on a diet of polystyrene plastics — commonly used to make Styrofoam — according to research published in
Mealworms devouring Styrofoam
the journal Environmental Science and Technology
. The findings point toward a possible solution for dealing with one of the most-polluting forms of plastic. In the study, 100 mealworms consumed between 34 and 39 milligrams of Styrofoam per day. These worms were as healthy as those fed a normal diet, the researchers report, and excreted biodegraded Styrofoam fragments that were usable as agricultural soil. While studies have found that other organisms, including waxworms and Indian mealmoth larvae, are able to digest plastics such as polyethylene, this is the first organism able to digest Styrofoam, which is generally considered non-biodegradable. The discovery could aid in better understanding of the conditions and enzymes that contribute to plastic degradation.

Icelandic Seafood Giant
May Be Involved in Endangered Whale Hunt
Iceland’s controversial annual hunt of fin whales — classified as "endangered" by the International Union for Conservation
of Nature — ended with a catch of 155 fin whales, the largest slaughter since the 1986 moratorium on commercial whaling, reports the London-based advocacy group Environmental Investigation Agency (EIA). The EIA and the Animal Welfare Institute obtained evidence
revealing the ongoing involvement of international seafood giant HB Grandi — a Reykjavík-based company with an annual income of roughly $230 million (as of 2011) — in the whaling business, despite its claims to the contrary. HB Grandi is Iceland’s largest seafood company and its CEO has repeatedly insisted that the company “is not involved in whaling and never has been.” Despite the international moratorium, Iceland recently has allowed commercial whaling and has shipped whale products to Japan.

Brown Carbon Plays Larger Role
In Climate Than Assumed, Study Says
Climate models are underestimating the effects of so-called brown carbon from sources such as forest fires because the models
do not account for regional factors — such as areas where wood-burning stoves are common — when estimating brown carbon's climate-warming impacts. Black carbon, primarily from urban combustion sources like vehicles and factories, absorbs the most sunlight, the researchers explain, and it's well-accounted for in climate models. However, most models don't properly account for brown carbon, the researchers say. Brown carbon "can be a significant absorber of sunlight, making it as bad for climate warming as black carbon," said co-author Manvendra Dubey of Los Alamos National Laboratory. The study, published this week in Nature Communications
, stresses the differing effects of black and brown carbon on the climate: Solid wood combustion, a source of brown carbon soot, is pervasive during United Kingdom winters, but very uncommon in other study locations, such as Los Angeles, which generally sees more black carbon soot from vehicles.

Liaoning Province ranks sixth in China in terms of aquaculture production, and this group of fish farms, which face the Yellow Sea, is the largest set constructed along the province's coastline. The fish farm basins are built on shallow seabeds, mudflats, and bays. Outer barriers protect the basins from winter storms and large waves generated by passing ships. Most aquaculture products are purchased live in China, with less than 5 percent being killed and processed for selling in local or foreign markets, the U.N. Food and Agriculture Organization (FAO), says. Shellfish, a traditional marine food source, still dominates China's marine production, according to the FAO's Fisheries and Aquaculture Department, accounting for 77 percent of the market.

New Agreement Yields Hope for
Saving World's Second-Largest Rainforest
In advance of the Paris climate talks, European and African countries announced
an initiative to stem the rising tide of forest destruction in Central Africa, one of the world’s last large expanses of rainforest. Norway is the first country to pledge funds to the Central African Forest Initiative (CAFI) — up to $47 million dollars per year through 2020 — to support the program. The agreement calls for the six participating Central African countries — Cameroon, the Central African Republic, the Democratic Republic of Congo, Equatorial Guinea, Gabon, and the Republic of Congo — to devise national investment plans that will tackle complex factors leading to deforestation, and it prioritizes long-term solutions over short-term, one-time actions. Central Africa is home to the world's second-largest tropical forest, but the region is increasingly under threat, mostly from small-scale slash-and-burn agriculture. Its preservation is key to global efforts to slow climate change, scientists say.

year if the city's buses were to run on electricity rather than diesel fuel, according to a study
by the Volvo Group and the audit and advisory firm KPMG. Factors such as noise, travel time, emissions, energy use, natural resource use, and roughly $2.9 million in avoided health care costs contributed to the annual savings, the analysis says. Gothenburg, Sweden's second-largest city, recently began operating a new electric bus line built by Volvo and powered by wind and hydro electricity, says Niklas Gustafsson, Volvo's head of sustainability. The buses' environmentally friendly design, combined with the fact that they are completely silent and emissions-free, has made the line popular in Gothenburg, he says.

future, saying in a statement that the reserves it had discovered were not “sufficient to warrant further exploration.” Shell began operating its first exploration well on July 30, 2015, in the Chukchi Sea off the northwestern coast of Alaska. But the company reported that although it had found indications of the presence of oil and gas, the reserves in the basin where they were drilling were, in the words of one company official, "clearly disappointing." Under Shell's federally approved exploration plan, all rigs and support vessels must leave the Chukchi Sea before the end of October. Environmental groups hailed Shell's announcement.

‘Pop-up’ Wetlands Will
Help Millions of Migrating Birds This Fall
Birds migrating south from the Arctic this fall will have access to 7,000 new acres of temporary wetland habitat for their California
stopovers, according to
researchers with NASA, The Nature Conservancy, and other academic and conservation organizations. The BirdReturns program creates “pop-up habitats” — temporarily flooded rice fields — for some of the millions of sandpipers, plovers, and other shorebirds that migrate each year from their summer Arctic breeding grounds to winter homes in California, which is in the midst of a severe drought, Mexico, and Central and South America. By combining on-the-ground observations and NASA satellite data, researchers can identify areas where birds flocked during previous migrations. Matching the location and timing of the pop-up wetland habitats with the route and timing of migrating shorebirds is critical, researchers say.

at the consumer level as people throw away spoiled or uneaten seafood at home, according to a new study. Researchers from the Johns Hopkins Center for a Livable Future estimated the edible U.S. seafood supply at 4.7 billion pounds a year, and said that 2.3 billion pounds of that are wasted. The study, published in the Journal Global Environmental Change
, said that 573 million pounds are lost annually as commercial fisherman catch and discard the wrong species. Roughly 330 million pounds are lost during distribution and retail, and 1.3 billion pounds are lost at the consumer level. The researchers recommended a number of changes to reduce the waste, including stricter limits on by-catch by commercial fishermen and efforts to encourage consumers to purchase frozen seafood.

New and Reactivated Coal
Mines Fell to Lowest Levels Ever Recorded
The opening of fewer new coal mines, combined with the closing of less-efficient mines, led to 2013 having the lowest number of active coal mines in the U.S. on record, according to an analysis
by the Energy Information Administration. In addition, the number of new and reactivated coal mines that began production in 2013 reached its lowest level in at least the past 10 years, the analysis says. Although 103 mines were added that year (the most recent year for which complete data are available), 271 mines were idled or closed, amounting to a 14-percent decline in the total number of productive coal mines compared to the previous year. The 2013 total was 397 fewer coal mines than in 2008, when U.S. coal production peaked. The declining number of new mines reflects reduced investment in the coal industry, strong competition from natural gas, stagnant electricity demand, a weak coal export market, and regulatory and permitting challenges, the EIA says.
Interview: A Scientist’s View
On How to Repair the Planet
For an environmental scientist who studies how humanity is pushing the earth close to potentially disastrous tipping points, Johan Rockström
of a new book, Big World, Small Planet
— is surprisingly optimistic. Although he reckons that our species has crossed four of nine “planetary boundaries,” including those on climate change and deforestation, he believes there is still time to pull back from the brink and create a sustainable future based on renewable energy and a “circular” economy that continually reuses resources. In an interview with Yale Environment 360
, Rockström describes how an alignment of science, technological advances, and a growing public hunger for action can get civilization back on track. “It’s not a journey where we are backing into the caves,” says Rockström. “It’s a journey of high technology ... and huge, multiple benefits.”

Antarctic Seafloor Life Is
Locking Away a Lot of Carbon, Study Says
The loss of sea ice over Antarctic waters has caused certain forms of life to flourish on the seafloor, and those underwater communities
An Antarctic icefish swimming over bryozoans
are acting as important and unexpected carbon sinks, according to research published in the journal Current Biology
. Based on studies of West Antarctic bryozoans — aquatic invertebrates sometimes referred to as "moss animals" — researchers have found that those and other seafloor organisms could play important roles in accumulating and burying carbon, removing it from the atmosphere for an extremely long time. The researchers calculate that growth of the bryozoans has nearly doubled over the past 20 years, with the animals taking in more than 200,000 tons of carbon per year since the 1980s. Accounting for other undersea species, the researchers suggest that roughly 3 million tons of carbon are sequestered each year, equivalent to nearly 200 square miles of tropical rainforest.

Rising seas and increasingly frequent and intense storms along the U.S. Atlantic and Gulf coasts could interact to produce alarming

. The study projects that coastal flooding could possibly shoot up several hundred-fold by 2100, from the Northeast to Texas. Even the study's most conservative calculations, based on greatly reduced greenhouse gas emissions over the next 85 years, suggest a 4- to 75-fold increase in the the combined heights and durations of expected floods. Over the past century, the East Coast has experienced sea level rise far beyond the 8-inch global average — up to a foot in much of the Mid-Atlantic and Northeast, including New York City. Most projections call for a further 2- to 4-foot rise by 2100, and some estimates go as high as 6 feet. At the same time, other studies suggest that in the future the largest North Atlantic storms may become more intense because warmer waters contain more energy.

for thousands of years, according to findings published in the journal Science
. The Arctic is an extreme environment, characterized by a cold climate and sparse vegetation. The typical diet of Greenlanders — and their ancient ancestors — is made up primarily of proteins and fats from fish and marine mammals, and carbohydrate and vegetable consumption is minimal. By collecting genetic information from 4,500 modern Greenlanders, researchers determined which genes have changed the most over the roughly 20,000 years since Greenlanders' most ancient Inuit ancestors separated from their nearest East Asian relatives, the Han Chinese. The genetic changes the researchers identified show that through natural selection the Greenlandic Inuit's genetic makeup evolved in a way that enabled them to efficiently metabolize the fatty acids from fish and to live with few carbohydrates and vegetables.

dollars annually, making it one of the world's largest illegal timber schemes, according to a new analysis by the Environmental Investigation Agency
(EIA). At stake are some of the most ecologically important remaining forests in Southeast Asia, EIA says. The report documents how Chinese businesses pay in gold bars for the rights to log entire mountains and smuggle timber out of Myanmar's conflict-torn state of Kachin. The stolen timber, primarily high-value species of rosewood and teak, is increasingly being sourced from deeper within Myanmar to feed factories in south and east China. The trade appeared to have peaked in 2005, when 1.3 million cubic yards of logs crossed the border. A brief hiatus then occurred when Chinese authorities intervened, but the scale is once again nearing peak levels, the EIA says.

Unchecked Consumerism Causing
Record-Breaking Resource Use, Study Says
Consumption of critical global resources — from meat and coffee to fossil fuels and water — has peaked in recent years, accelerating

climate change, pollution, and resource depletion to unsustainable levels, according to an analysis
by the Worldwatch Institute. The report tracked 24 global consumption trends and found many of them to be record-breaking. Meat production, for instance, has more than quadrupled in the last 50 years, leading to large-scale pressure on water, feeds, and grazing land. Aquaculture production has increased roughly 10 fold since 1984, and today farmed fish account for nearly half of all fish eaten. Global plastic production has also risen continuously over the past 50 years, while recycling rates remain very low. In the United States, for example, only 9 percent of plastic was recycled in 2012. “Untrammeled consumerism lies at the heart of many of these challenges,” said author Michael Renner.
