In Germany, the Netherlands, Denmark and other countries, European governments are beginning to push farmers, industry, and municipalities to cut back on fertilizers and other sources of nitrogen that are causing serious environmental harm.
Innovative government policies have helped propel Texas into the forefront of wind energy generation in the U.S. But the main impetus for the Lone Star State’s flourishing wind sector is the revenue it has generated for landowners and local communities.
With the Keystone XL and other pipeline projects running into stiff opposition, Alberta’s tar sands industry is facing growing pressure to find ways to get its oil to market. One option under consideration would be to ship the oil via an increasingly ice-free Arctic Ocean.
The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans’ heat-buffering ability may be weakening.
For two towns in northern India, melting glaciers have had very different impacts — one town has benefited from flowing streams and bountiful harvests; but the other has seen its water supplies dry up and now is being forced to relocate.
For decades, the slaughter of sharks – sought after for their fins and meat – has been staggering. But bans on finning and new attitudes in Asia toward eating shark fin soup are leading to optimism about the future for these iconic ocean predators.
In the American West, where sage grouse populations have plummeted, conservationists, ranchers, and oil and gas companies are taking part in an experiment in which private landowners are paid to protect and restore critical habitat for the beleaguered bird.
Drinking water supplies around the world often contain trace amounts of pharmaceuticals and synthetic compounds that may be harmful to human health. One solution being tried in the U.S. and Europe is to construct man-made wetlands that naturally degrade these contaminants.
It’s not just the potential for a catastrophic spill that makes President Obama’s proposal to open Atlantic Ocean waters to oil exploration such a bad idea. What’s worse is the cumulative impact on coastal ecosystems that an active oil industry would bring.
Blessed with lots of sun and keen to cut its reliance on imported oil, Hawaii has moved to the forefront of residential solar installations in the U.S. But financial and technical hurdles are slowing the state’s drive to generate 40 percent of its electricity from renewable energy by 2030.
Interview: For Buddhist Leader,
Religion and Environment Are One
Ogyen Trinley Dorje, spiritual leader of a 900-year-old lineage of Buddhism, says his deep concern for environmental issues
His Holiness the 17th Karmapa
stems from his boyhood living close to the land on the Tibetan plateau. Now, as His Holiness the 17th Karmapa, he is promoting a program that seeks to instill good environmental practices in Buddhist monasteries in the Himalayan region. In an interview with Yale Environment 360
, the Karmapa talks about how ecological awareness fits with the Buddhist concept of interdependence, why the impacts of climate change in the Himalaya are so significant, and what role religion can play in helping meet the world’s environmental challenges. “The environmental emergency that we face is not just a scientific issue, nor is it just a political issue,” he says. “It is also a moral issue.”

A new online mapping tool could help governments and investors evaluate the geothermal energy potential for locations around
the globe through satellite measurements, lowering the risks and costs involved in developing this clean energy source, its creators say. The tool
uses gravity measurements from European Space Agency (ESA) satellites to look for certain characteristics unique to geothermal reservoirs, including areas with thin crusts, subduction zones, and young magmatic activity. This helps determine which locations are most likely to possess geothermal energy potential, narrowing the search — and cost — for prospectors. The project, which is a partnership between the ESA and the International Renewable Energy Agency (IRENA), will "help make a strong business case for geothermal development where none existed before,” said a director at IRENA.
Canine Conservation: Using Dogs
In War Against Poachers in Kenya
In Kenya’s Ol Pejeta Conservancy — home to some of the most endangered subspecies of rhinoceros — officials are deploying a new weapon to combat rampant rhino poaching: highly trained K-9 dogs. Six Belgian Malinois tracking and attack dogs are now working with Kenyan rangers to protect tiny populations of northern white rhinos and eastern black rhinos, which have been hunted to near-extinction by poachers seeking rhino horn for supposed medicinal purposes. Overseen by a former military dog instructor with the U.K. Royal Army Veterinary Corps, the K-9 units are being deployed not only in Ol Pejeta but also in a Tanzanian park that has been plagued by poaching.

The second annual Yale Environment 360 Video Contest is now accepting entries. The contest honors the best environmental videos. Entries must be videos that focus on an environmental issue or theme, have not been widely viewed online, and are a maximum of 15 minutes in length. Videos that are funded by an organization or company and are primarily about that organization or company are not eligible. The first-place winner will receive $2,000, two runners-up will each receive $500, and all winning entries will be posted on Yale Environment 360
. The contest judges will be Yale Environment 360
editor Roger Cohn, New Yorker
writer and e360
contributor Elizabeth Kolbert, and documentary filmmaker Thomas Lennon. The deadline for entries is June 15, 2015.
Interview: Why This Tea Partyer
Is Seeing Green on Solar Energy
Debbie Dooley’s conservative credentials are impeccable. She was one of the founding members of the Tea Party movement and
continues to sit on the board of the Tea Party Patriots. But on the issue of solar power, Dooley breaks the mold. To the consternation of some of her fellow conservatives, she has teamed up with the Sierra Club and other environmental organizations, first in Georgia and now in Florida, to form the Green Tea Coalition. The group is working to get an initiative on the Florida ballot that would allow individuals and businesses to sell power directly to consumers. In an interview with e360
, Dooley explains why she supports solar energy campaigns and why she’s willing to go up against conservative organizations when it comes to this issue.

A large reservoir of methane — a greenhouse gas many times more potent than carbon dioxide — was recently discovered on
Knipovich Ridge in the Arctic Ocean
Knipovich Ridge in the central Arctic Ocean, according to
research published in the journal Geology
. The methane in this deposit is locked up in icy crystals of water and gas called hydrates, and it was produced by abiotic geological processes rather than by microbes breaking down organic matter, as most methane is, the authors explain. Until now, scientists had not known that hydrates could contain this type of methane. "Up to 15,000 gigatons of carbon may be stored in the form of hydrates in the ocean floor, but this estimate is not accounting for abiotic methane," said co-author Jürgen Mienert. "So there is probably much more."
