Wood Pellets: Green Energy or New Source of CO2 Emissions?
Burning wood pellets to produce electricity is on the rise in Europe, where the pellets are classified as a form of renewable energy. But in the U.S., where pellet facilities are rapidly being built, concerns are growing about logging and the carbon released by the combustion of wood biomass.

After Steep Decline, Signs of Hope for World’s Sea Turtles
Nearly all sea turtle species have been classified as endangered, with precipitous declines in many populations in recent decades. But new protections, particularly in the U.S. and Central America, are demonstrating that dramatic recovery for these remarkable reptiles is possible.

Can Green Bonds Bankroll A Clean Energy Revolution?
To slow global warming, tens of trillions of dollars will need to be spent in the coming decades on renewable energy projects. Some banks and governments are issuing green bonds to fund this transformation, but major questions remain as to whether this financing tool will play a game-changing role.

In Romania, Highway Boom Poses Looming Threat to Bears
Romania, one of Europe’s poorest nations, badly needs a modern highway system. But conservationists warn that unless the movements of wildlife are accommodated, a planned boom in road construction could threaten one of the continent’s last large brown bear populations.

Fast-Warming Gulf of Maine Offers Hint of Future for Oceans
The waters off the coast of New England are warming more rapidly than almost any other ocean region on earth. Scientists are now studying the resulting ecosystem changes, and their findings could provide a glimpse of the future for many of the world’s coastal communities.

A Scourge for Coal Miners Stages a Brutal Comeback
Black lung — a debilitating disease caused by inhaling coal dust — was supposed to be wiped out by a landmark 1969 U.S. mine safety law. But a recent study shows that the worst form of the disease now affects a larger share of Appalachian coal miners than at any time since the early 1970s.

Fostering Community Strategies For Saving the World’s Oceans
To conservationist Ayana Elizabeth Johnson, getting coastal communities involved in plans to protect their waters is critical for protecting the planet's oceans. In an interview with Yale Environment 360, she talks about her work in one Caribbean island and how it shows how such a strategy can get results.

A Conservationist Sees Signs of Hope for the World’s Rainforests
After decades of sobering news, a prominent conservationist says he is finally finding reason to be optimistic about the future of tropical forests. Consumer pressure on international corporations and new monitoring technology, he says, are helping turn the tide in efforts to save forests from Brazil to Indonesia.

Beyond Treaties: A New Way of Framing Global Climate Action
As negotiators look to next year’s UN climate conference in Paris, there is increasing discussion of a new way forward that does not depend on sweeping international agreements. Some analysts are pointing to Plan B — recasting the climate issue as one of national self-interest rather than global treaties.

Cashes Ledge: New England’s Underwater Laboratory
A little over 70 miles off the coast of New England, an unusual undersea mountain range, known as Cashes Ledge, rises from the seabed. The area teems with kelp forests, sea sponges, and a wide variety of fish and mollusks — much of it captured by ocean photographer Brian Skerry during dives made earlier this year
