From Britain to the Czech Republic, European nations have been restoring rivers to their natural state — taking down dams, removing levees, and reviving floodplains. For a continent that long viewed rivers as little more than shipping canals and sewers, it is a striking change.
As debate over the Keystone XL and other pipeline projects continues, crude oil from the Alberta tar sands and western U.S. oil fields is increasingly being hauled by railroad. Critics warn that this development poses a threat not only to the environment but to public safety.
India is planning to burn more of its trash to generate badly needed electricity. But as the case of a waste-to-energy plant in New Delhi shows, critics are worried about lax air pollution controls and the impact of incineration on people who eke out a living picking through waste dumps.
Endangered North Atlantic right whales are disappearing from customary feeding grounds off the U.S. and Canadian coasts and appearing in large numbers in other locations, leaving scientists to wonder if shifts in climate may be behind the changes.
A shortage of "rare earth" metals, used in everything from electric car batteries to solar panels to wind turbines, is hampering the growth of renewable energy technologies. Researchers are now working to find alternatives to these critical elements or better ways to recycle them.
Large-scale solar projects are enjoying steady growth in California and the southwestern United States. But will shifting government incentives and mandates slow the expansion of this key part of the solar energy industry?
After three decades of unbridled economic growth and mounting ecological problems, China and its new leadership face a key challenge: cleaning up the dirty air, polluted water, and tainted food supplies that are fueling widespread discontent among the country’s burgeoning middle class.
Recent studies in Asia and Australia found that community-managed areas can sometimes do better than traditional parks at preserving habitat and biodiversity. When it comes to conservation, maybe local people are not the problem, but the solution.
China is engaged in a push to build hydroelectric dams on a scale unprecedented in human history. While being touted for producing lower-emission electricity, these massive dam projects are wreaking havoc on river systems across China and Southeast Asia.
One year after Hurricane Sandy devastated parts of the U.S. East Coast, the government is spending billions to replenish beaches that will only be swallowed again by rising seas and future storms. It’s time to develop coastal policies that take into account new climate realities.
Although the latest U.N. climate report significantly increases its projections for sea level rise this century, some scientists warn even those estimates are overly conservative. But one thing is certain: Predicting sea level rise far into the future is a very tricky task.
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.
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.
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.
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.
Fish 2.0: A Contest Seeks to Foster
A More Sustainable Seafood Industry
Twenty pioneers in the sustainable seafood business climbed a stage at Stanford University in November in an effort to woo the judges at the Fish 2.0 contest

with proposals on how to change the way the U.S. catches, distributes, and markets fish. A business competition at heart, Fish 2.0 brought together entrepreneurs and investors to spur innovation in the tradition-bound seafood industry. Competitors's proposals ranged from converting waste at fish processing plants to expanding a Hawaiian network of aquaponic growers, who raise fish and vegetables together in tanks, into the developing world. One proposal aimed to create a data system to track catches in real time, enabling fisheries managers to hold the line on harvests. Contestants headed home with more than $75,000 in prize money.

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.
