Volume of E-Waste
Projected to Soar by 2017, Study Says
The volume of electronic waste generated worldwide is expected to climb by 33 percent by 2017
to 65 million tons, according to a study conducted by a partnership of United Nations organizations, industry, governments, and scientists. So many computers, televisions, mobile
phones, and other devices are being tossed away annually that within four years the volume of e-waste would fill a 15,000-mile line of 40-ton trucks, the report
said. The report, released by a group called StEP
( Solving the E-Waste Problem Initiative) said that in 2012, 50 million tons of e-waste was generated worldwide, about 15 pounds for every person on the planet. China generated the most electronic waste last year, with 11.1 million tons, followed by the U.S. with 10 million tons. But in per capita generation, the U.S. dwarfed China and most other countries, with each American producing 65 pounds of e-waste, the study said. “The explosion is happening because there is so much technical innovation,” said Ruediger Kuehr, executive secretary of StEP.

U.S. Energy Department
Invests in Small-Scale Nuclear Reactors
Small, nearly meltdown-proof nuclear reactors are receiving a big boost from the U.S. Department of Energy
. The department will give a company in Corvallis, Oregon, as much as $226 million to develop so-called "small modular reactors," which can be used with many local power grids that can't accommodate conventional nuclear reactors. Because of the extremely low likelihood of meltdown, the next-generation, small-scale reactors are safer than many currently operating reactors, engineers say. The company, NuScale Power, plans to encase their reactors in something akin to a large thermos, which would sit at the bottom of a pool. If a reactor fails and threatens to overheat, the container would fill with water and remove excess heat without pumps or valves, which can sometimes fail. The Energy Department's investment is the second one in a $452 million, multi-year program to accelerate the development of such reactors. The reactor designs use water as a coolant, which is technologically conservative and increases the likelihood that the small modular reactors would be approved by the Nuclear Regulatory commission, The New York Times

Final Shipment of Russian
Warhead Uranium Set to Reach U.S. Today
A U.S. nuclear storage facility today will receive the final shipment of decommissioned nuclear warheads from Russia, NPR reports
. Since 1993 the Russian uranium has been generating 10 percent of all electricity consumed in the U.S., part of a deal struck with the former Soviet state when its nuclear industry, crippled by arms reduction agreements, was struggling to make
Russian uranium ready for shipment to U.S.
ends meet. Negotiations began when a U.S. official visited Russia in the early 1990s and found bomb-grade uranium from thousands of decommissioned warheads lying around in crumbling storage facilities. Concerned that the radioactive material was unsecured and vulnerable to theft, the U.S. asked to buy it. Russian officials reluctantly agreed to convert roughly 500 tons of bomb-grade uranium into nuclear fuel and sell it to the U.S. Experts say it was a win-win scenario: Russia made a substantial profit ($17 billion), U.S. power plants could buy the uranium at a good price, and 20,000 bombs' worth of radioactive material was converted into relatively clean electricity. The deal will go down in history as one of the greatest diplomatic achievements ever, one expert told NPR.

Chinese State Media
Criticized for Touting Benefits of Smog
For Chinese citizens worried about smog, which has been blanketing major cities and smashing air pollution records recently, China's state media has some advice: Look on the bright side. State broadcaster CCTV and a Communist Party tabloid, Global Times
, yesterday published editorials
attempting to put a positive spin on China's air pollution crisis. The state-run outlets said smog has military benefits because it can interfere with the guidance systems of foreign missiles, as well as personal benefits such as bolstering Chinese citizens' sense of humor, making them more united, more sober, better informed, and more equal because smog "affected the lungs of both rich and poor," The Telegraph
reports. Internet commenters and other media outlets, including several state-run publications, were outraged. "Is the smog supposed to lift if we laugh about it?" asked the official publication Beijing Business Today
. The pro-smog pieces have both been deleted from the publications' websites.

Intensifying Storms Are
Contributing To Ongoing U.S. Wetlands Loss
The U.S. is losing wetlands at a rate of 80,000 acres per year, in part because of intensifying coastal storms and sea level rise, according to a new government study
. From 2004 to 2009, the country lost more than 360,000 acres of freshwater and saltwater wetlands, a decline driven both by traditional factors, such as coastal development, as well as worsening storms and slowly rising seas, the study says. The rate of loss is a signal that government efforts to protect and restore wetlands are failing to keep pace with major environmental changes, experts told The Washington Post
. The most pronounced wetlands losses were along the Gulf of Mexico, where major hurricanes have wreaked havoc on coastal lands. Along the Atlantic coast, a rapid increase in coastal development is funneling stormwater runoff into wetlands that cannot handle it, the study said. The loss rate of 80,000 acres annually represents a 25 percent increase over the rate of wetlands loss during 1998-2004, the last time government agencies examined the problem.
Five Questions For Jerry Brown
On the West Coast Climate Pact
California Governor Jerry Brown was one of the moving forces behind a new agreement among three Western states and British Columbia to align their policies to combat climate change. Under the pact, signed on Oct.
28 by Brown and the governors of Oregon and Washington, the states and the province agreed to a series of actions, including putting a price on carbon and adopting a low-carbon fuels standard. Yale Environment 360
spoke with Brown and asked him five questions about the pact and overall efforts to tackle climate change.

Urban Car Use Declines
As Biking and Public Transit Rise in the U.S.
Americans in urban areas are driving less, biking more, owning fewer cars, and using public transportation more frequently, according to new research by the U.S. Public Interest Research Group
(U.S. PIRG). The number of people driving to work fell in 99 of 100 major urban areas between 2006 and 2011, and the number of miles driven by car fell in three-quarters of the cities studied over that time, the PIRG study showed. The proportion of people biking to work increased in 85 of 100 cities, while the number of miles traveled on public transit increased in 60 of 98 cities. Meanwhile, the number of people working from home grew in all 100 cities, the report said. From 2004 to 2012, the average number of vehicle-miles driven per person decreased by 7.6 percent nationwide. "There is a shift away from driving,” said Phineas Baxandall, an analyst for the U.S. PIRG Education Fund. "Instead of expanding new highways, our government leaders should focus on investing in public transit and biking for the future."

New Paper Offers Sweeping
Plan to Decarbonize the Global Economy
Eighteen prominent international climate scientists and economists have authored a paper
that seeks to answer the most vexing environmental question facing the planet: How to reverse soaring carbon dioxide emissions and prevent the world from experiencing destabilizing climate change. Their answer, presented in the journal PLOS One,
boils down to this: Offer global leaders a detailed blueprint for decarbonization that involves setting a steadily rising price on carbon, the large-scale deployment of nuclear power and renewable energy, increased research into low-carbon energy technologies, and a reform of forestry and agricultural policies that leads to massive sequestration of CO2 — all while not spending more than 1 percent of global gross economic output. “In terms of economics, comparing a path to decarbonization versus a path of wrecking the planet are not even close,” economist Jeffrey Sachs, a co-author of the paper and director of Columbia University’s Earth Institute, said at a press briefing. “We haven’t shown the path of decarbonzation clearly enough (and) what the real choices are.”

China Set to Open
World's Second Largest Carbon Market
China is in the midst of launching seven carbon markets, the largest of which will open next month in Guangdong
, the country's most populous province. The carbon markets are a key element of China's plan to cut carbon emissions by up to 45 percent per unit of GDP by 2020. The Guangdong carbon permitting scheme will cap 2013 emissions at 350 tons for 202 companies in the heavily industrialized province. Twenty-nine million permits will be auctioned in the market this year and next, which will be the world's second largest carbon market after the European Union's, dwarfing carbon markets in Australia and California. In 2015 the number of permits auctioned will more than triple, officials said. Shanghai's carbon market launched yesterday and a similar market, about a quarter of the size of Guangdong's, is set to open in Beijing tomorrow. China's seven carbon markets together will regulate roughly 700 to 800 million tons of CO2 annually, roughly equal to the annual emissions of Germany.

Despite Discord, Climate Talks
in Warsaw End With Last-Minute Deals
After more than 36 hours of continuous negotiations, delegates at the U.N. climate talks in Warsaw agreed to two last-minute deals that kept alive hopes for staving off climate change. At talks that ended Saturday, delegates agreed to a proposed system for pledging cuts in greenhouse gas emissions. They also gave support to a new treaty mechanism for tackling the human cost of the effects of global warming, including floods, rising seas, and stronger storms, The New York Times reports
. Parties also agreed that countries will have until early 2015 to lay out their plans for cutting greenhouse gas emissions. Those plans are to be published in advance of a major U.N. climate meeting in Paris, set for late 2015, at which international leaders hope to reach an agreement to curb global emissions starting in 2020. Discord and acrimony characterized the talks, during which a vocal negotiating bloc emerged among developing countries, including India, China, and Saudi Arabia. This bloc forced the watering down of key aspects of the deal, according to the Guardian

Majority of Americans
Uninformed About Fracking, Survey Finds
Most Americans are uninformed and lack opinions on hydraulic fracturing, or fracking, a process used to extract oil and gas from rock formations, a new survey says
. Fifty-eight percent of people surveyed specifically reported that they knew nothing at all about fracking, and the same percentage said they didn't know whether they supported fracking or opposed it. Seven percent said they were aware of some of the process's environmental impacts, and 3 percent said they knew of positive economic and energy supply impacts of fracking. Of those who held an opinion on it, 20 percent were opposed to fracking and 22 percent supported it. "Broadly speaking, our results paint a picture of an American populace that is largely unaware and undecided about this issue," the study says. The study
— conducted by researchers at Oregon State, George Mason, and Yale universities — was recently published in the journal Energy Policy

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.
Interview: How Big Agriculture
Has Thwarted Factory Farm Reforms
In 2008, the Pew Commission on Industrial Farm Animal Production released a landmark report
that condemned the way the U.S. raised its cattle, pigs, and
chickens and made a sweeping series of recommendations on how to reduce the severe environmental and public health problems created by the current system. Last month, the Johns Hopkins Center for a Livable Future released a study
analyzing the fate of these reforms and reached a stark conclusion: The power of the industrial agriculture lobby had blunted nearly all attempts at change. In an interview with Yale Environment 360
, Robert Martin, co-author of the Johns Hopkins report, discusses what went wrong and how reforms can proceed. One hopeful sign, says Martin, is "there are more and more people who are concerned about where their food comes from and how it’s produced."Read the interview.

U.N. Climate Chief Says
Many Coal Reserves Must Be Left in Ground
United Nations climate chief Christiana Figueres said that coal power can be part of the solution to curbing global warming, but it would require shuttering older coal power plants, advancing carbon capture and storage (CCS) technology, and resolving to leave much of the planet's existing coal reserves in the ground. Her remarks, given at the International Coal and Climate Summit in Warsaw, are drawing criticism from environmentalists who oppose continued reliance on coal power. John Gummer, the chair of the U.K.'s climate advisers and former U.K. environment minister, told the Guardian
that "calling coal a clean solution is like characterizing sex trafficking as marriage guidance." Figueres said that coal power holds promise as a means of helping poorer countries develop their economies and reduce poverty, but said that the industry "must change." Figueres joins the growing list
of climate leaders who say that more than half of remaining fossil fuel reserves must be left in the ground
in order to avoid massive carbon emissions that could destabilize the climate.

U.S. Crushes Six Tons
Of Illegally Trafficked Elephant Ivory
The U.S. Fish and Wildlife Service
(FWS) destroyed six tons of elephant ivory
today that field agents seized over the past 25 years. The U.S. Ivory Crush event, which took place in Denver, Colorado, marked the first time
the FWS has destroyed large quantities of ivory. The move was an attempt to send a clear message that the U.S. will not tolerate illegal ivory trafficking and the toll it's taking on elephant populations in Africa and Asia, the FWS said. Seized ivory is usually kept as evidence for prosecuting traffickers, then later used for education and training, but the FWS had accumulated far more ivory than it needs. The ivory that was crushed included full tusks, carved tusks, jewelry, carvings, and other objects, and came from at least 2,000 poached elephants, the FWS estimates.

China's Renewable Power
Sector Set to Outpace Rest of World by 2035
China is on track to generate more electricity from renewable energy by 2035 than the U.S., the European Union, and Japan combined, the International Energy Agency (IEA) said in a new report
. In its World Energy Outlook report, the IEA also said that by 2035 renewable energy sources — wind, solar, hydropower, and biomass — will make up more than 30 percent of the world's electricity supply, surpassing natural gas and rivaling coal as the leading energy source. Wind and solar photovoltaic power will see especially large gains, helping renewable energy account for nearly half the increase in global power generation over the next two decades, the IEA said. Carbon emissions related to energy generation will likely rise by 20 percent over that time, the report said, but policies and initiatives in the U.S., China, Europe, and Japan may help limit those emissions. "The right combination of policies and technologies is proving that the links between economic growth, energy demand and energy-related carbon dioxide emissions can be weakened," the IEA said.

Ozone Treaty From 1987
Has Also Slowed Global Warming
The 1987 Montreal Protocol, an international treaty designed to protect the ozone layer by banning chlorofluorocarbons (CFCs), has also slowed global warming since the mid-1990s, a new analysis has found
. The ban has lowered global temperatures by about 0.2 degrees F since it was enacted, scientists report in the journal Nature Geoscience
. Researchers say that's a significant decline considering the planet has warmed by an average of 1.6 degrees F since 1900. CFCs, a class of refrigerants banned because of their ozone-depleting qualities, are also powerful greenhouse gases, with warming potentials many thousands of times higher than CO2. A widely used replacement for CFCs — hydrofluorocarbons, or HFCs — are less powerful greenhouse gases, but negotiations are underway to amend the Montreal Protocol to apply to HFCs as well. The study's lead author, Francisco Estrada of the National Autonomous University of Mexico, told Climate Central that by "pure luck" the Montreal Protocol has effectively slowed global warming, even more so than the Kyoto Protocol, which was was directly aimed at reducing greenhouse gas emissions.

Beijing To Limit New Cars
By 40 Percent in Anti-Pollution Drive
In an effort to reduce severe air pollution in the Chinese capital, Beijing will limit by 40 percent the number of new cars sold annually for the next four years, cutting license plate allocations from 240,000 to 150,000 each
Chang'an avenue in Beijing
year. The cap, which should also help ease the capital's worsening traffic congestion, means Beijing will license only 600,000 new cars between 2014 and 2017 — fewer than in 2010 alone, Reuters reports
. By 2017, 40 percent of those licenses, which drivers vie for in auctions and lotteries, will be reserved for hybrid and electric cars. New car sales in China are currently capped in four cities — Beijing, Shanghai, Guangzhou, and Guiyang — and the government plans to limit sales in eight additional cities, the China Association of Automobile Manufacturers said.

Treaties May Not Be The
Key to Global Sustainable Development
Sweeping international treaties are no longer the key for charting the planet’s path to sustainable development, according to international leaders gathered at the “Rio+20 to 2015” conference last week. Instead, they said, partnerships among governments, businesses, and NGOs hold the most promise for measurable progress on sustainability issues, including climate change. "There’s been an enormous focus on treaties," Hans Hoogeveen, director general of the Dutch Ministry of Economic Affairs, told the conference at Yale University. "Lawyers and diplomats think they can rule the world, govern the world, from New York, Nairobi, or Rome. I think we have to learn that this not reality anymore." The United Nations convened a summit in Rio in 2012 to secure sustainability commitments from private businesses, societal groups, and leaders at all levels of government. Last week’s conference sought to develop recommendations for producing timely, measurable results from those commitments before international talks planned for Paris in 2015.Read more

Obama to Sign Order
Calling For Adaptation to Climate Change
President Obama was expected to sign an executive order on Friday
directing federal agencies to make it easier for states and communities to adapt to the rising seas, more intense storms, and droughts that are expected to increase as the planet warms this century. A key aspect of the order aims to ensure that states and local communities take into account likely climate conditions in the future when they spend federal money on projects like roads, bridges, and flood control structures. Critics say that such planning has often been lacking
as the northeastern U.S. rebuilds from Hurricane Sandy. Obama’s executive order also will set up a task force of state and local leaders to advise the federal government on how best to enable local communities to plan for storms, droughts, and disasters as temperatures increase. “All of that is going to be shaped by the awareness of climate change and the things that can be done to make those investments produce a much more resilient society,” said John P. Holdren, the president’s science adviser.

Three Western U.S. States And
British Columbia Sign Climate Agreement
The governors of California, Oregon, and Washington, together with the premier of British Columbia, have signed a pact to coordinate efforts to combat global warming. With a combined GDP of $2.8 trillion and a population of 53 million people, the three states and the Canadian province represent the world's fifth largest economy. The leaders agreed to a dozen actions aimed at curbing greenhouse gas emissions, including streamlining permits for renewable energy projects, improving the electric power grid, supporting more research on ocean acidification, and expanding government purchases of electric vehicles, the San Jose Mercury News reports
. Environmentalists have praised the agreement, but, as Jeremy Carl, an energy policy fellow at Stanford University, noted, "The devil will be in the details, whether they do anything substantive or whether it turns out to be a time-wasting exercise."

Major Pension Funds Question
Long-Term Outlook for Fossil Fuel Profits
Leaders from some of the largest pension funds in the U.S. and the world are concerned about the future profitability of fossil fuel companies, and they have asked those companies to report on their plans for managing a long-term shift
toward renewable energy. Managers of 70 major pension funds, which together control about $3 trillion in investments, asked 45 of the world's largest coal, oil, gas, and electric power companies to complete the profitability studies by spring. The pension funds are concerned that, because large investments in fossil fuel exploration take decades to recoup, future legislation could limit production or regulate expensive pollution controls that will significantly cut profitability. "The scientific trajectory that we're on is clearly in conflict" with the business strategy of the companies
, Jack Ehnes, the head of the California's State Teachers' Retirement System, told the AP. "We've been pleasantly surprised by the seriousness" of some of the fossil fuel companies, who are "not just blowing us off," a spokesman for the coalition that is coordinating the efforts told the AP.

Climate-Driven Disasters To Keep
Impoverished Populations Poor, Study Says
Extreme weather events driven by climate change will exacerbate poverty in regions where people are already among the world's poorest, according to a study
by the U.K.'s Overseas Development Institute. Where disasters
Floods in Mozambique
such as drought are common, those events are the leading cause of poverty, the authors say, rather than poor health or societal factors. Across the globe, up to 325 million people will be living in countries that face natural hazard risks by 2030, the report says; in sub-Saharan Africa alone, 118 million people in poverty will face extreme events. To brace against the effects of disasters
, aid money should be spent on reducing those risks, rather than only on humanitarian relief after an extreme event, the authors argue. Currently, money tends to flow to a region after a disaster instead of before, when it could be used for prevention. "If the international community are serious about ending extreme poverty, they need to get serious about reducing disaster risk for the poorest people," the institute's Tom Mitchell told the BBC.

Antarctic Research Operations
To Be Halted Amid U.S. Government Shutdown
The National Science Foundation (NSF) says it is curtailing the 2013-2014 Antarctic research season because the U.S. government shutdown has delayed funding for operations there. The U.S. Antarctic
Program, which is managed by the NSF, announced yesterday
that the three U.S. research stations, ships, and other facilities there will switch to "caretaker status" when funds are exhausted around October 14. All research activities not essential to human safety and preservation of property will be suspended, according to the statement. Because of the remote location and long lead time necessary for planning and travel, the NSF has already started the process of shuttering research facilities. Once funding is restored, some research operations could be restored, the U.S. Antarctic Program said. Around 700 scientists typically travel to the continent between October and February each year, according to Nature
Forum: Climate Scientists Assess
The Latest Report from U.N. Panel
The U.N. Intergovernmental Panel on Climate Change recently issued a report containing the latest data and

IPCC Scientists Warn
Of Upper Limit on CO2 Emissions
Saying it is 95 percent certain that humans have caused most of the global warming of the last half-century, scientists with the Intergovernmental Panel on Climate Change (IPCC) warned today that the world can afford to burn about 1 trillion tons of carbon
before facing extreme climate change. The IPCC’s working group on the physical sciences for the first time set an upper limit on CO2 emissions, contending that humanity can combust only one-third of the 3 trillion tons of fossil fuels that still remain in the ground. If carbon emissions continue at their current pace, IPCC scientists forecast that the trillionth ton of carbon will be released around 2040, and beyond that the world will face potentially destabilizing temperature increases exceeding 2 degrees C, or 3.6 degrees F. The physical sciences report,
compiled by hundreds of scientists and released in Stockholm, marked the first time that the IPCC had forecast that sea levels could rise by as much as three feet this century. The physical sciences report is the first of several to be released in the next year in advance of the 2014 publication of the IPCC’s fifth report on global climate change.

Major Initiative Announced
To Help Curb Elephant Poaching in Africa
The Clinton Global Initiative and 16 conservation organizations have announced that they are investing $80 million
over three years to stem the epidemic of elephant poaching in Africa, which has surged recently due to increasing demand for ivory in Asia. The Partnership to Save Africa's Elephants, which includes the governments of seven African nations, will fund programs that scale up anti-poaching enforcement, combat trafficking at ports and markets with more enforcement and harsher penalties, and curb the demand for illegal ivory with ad campaigns aimed at consumers in China, Vietnam, and other nations. "We cannot hope to reverse the dramatic decline in elephant populations without addressing all three parts of the problem," said Patrick Bergin, CEO of the African Wildlife Foundation.

U.S. Places CO2 Limits
On New Coal-Fired Power Plants
The U.S. Environmental Protection Agency will for the first time begin regulating carbon dioxide emissions from new coal- and natural gas-fired power plants
under the Clean Air Act, EPA Adminstrator Gina McCarthy announced. Speaking in Washington, McCarthy said, “Climate change is real, human activities are fueling that change,
and we must take action to avoid the most devastating consequences.” The EPA regulations, which the coal industry vows to challenge in court, will require new coal plants to emit fewer than 1,100 pounds of carbon dioxide per megawatt hour, considerably lower than the average 1,800 pounds of CO2 per megawatt hour currently produced by coal-fired power plants. Such limits would require the new plants to deploy carbon capture and storage (CCS) technology, which has not been used on a wide scale. The difficulty of using CCS technology will be at the heart of lawsuits challenging the EPA move, industry officials say.

Climate Change Reporting
Focuses on Disasters and Uncertainty
Nearly 80 percent of news articles about climate change either warn of current or future disaster scenarios related to global warming, or contain discussions about the uncertainty of climate science, an Oxford study of 350 news articles
from 2007 to 2012 has found. Fewer than two percent of the articles from the media in six countries discussed opportunities to be gained from switching to a lower-carbon economy. Journalists were attracted to "gloom and doom" stories about climate-related disasters, the team wrote, which is in line with findings from previous studies. Uncertainty was discussed in nearly 80 percent of the articles, which the researchers say poses a problem for dealing with climate change
because it keeps debate focused on what's considered conclusive proof of global warming
, rather than directing discussion toward the comparative costs and risks of different policy options.

Canadian Scientists Fight Back
Against Government Censorship Rules
Recent rules silencing government researchers in Canada have sparked protests in 16 major cities, the Guardian reports
. The Harper administration over the past few years has ordered scientists at Canada's National Research Council, Fisheries and Oceans Canada, and other government research agencies not to discuss work on a number of climate- and environment-related issues with journalists, the public, or even fellow researchers. Scientists have been asked not to comment on topics ranging from snowflakes to salmon, even after results have been published in major scientific journals. Critics charge that the Harper administration has a track record of muzzling environmental research
. Earlier this month the administration was accused of stalling a major report on greenhouse emissions — widely expected to document significant rises in carbon pollution — because the study could deal a blow to Harper's efforts to secure U.S. approval of the Keystone XL pipeline, the Guardian reports.
