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.

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.

What Is the Carbon Limit? That Depends Who You Ask
Scientists are offering widely varying estimates of how much carbon we can emit into the atmosphere without causing dangerous climate change. But establishing a so-called carbon budget is critical if we are to keep the planet a safe place to live in the coming century.

For Cellulosic Ethanol Makers, The Road Ahead Is Still Uphill
While it has environmental advantages over other forms of ethanol, cellulosic ethanol has proven difficult to produce at commercial scale. Even as new production facilities come online in the U.S., a variety of economic and market realities suggest the new fuel still has big challenges to overcome.

Innovations in Energy Storage Provide Boost for Renewables
Because utilities can't control when the sun shines or the wind blows, it has been difficult to fully incorporate solar and wind power into the electricity grid. But new technologies designed to store the energy produced by these clean power sources could soon be changing that.

Drive to Mine the Deep Sea Raises Concerns Over Impacts
Armed with new high-tech equipment, mining companies are targeting vast areas of the deep ocean for mineral extraction. But with few regulations in place, critics fear such development could threaten seabed ecosystems that scientists say are only now being fully understood.

Electric Power Rights of Way: A New Frontier for Conservation
Often mowed and doused with herbicides, power transmission lines have long been a bane for environmentalists. But that’s changing, as some utilities are starting to manage these areas as potentially valuable corridors for threatened wildlife.

The Case Against a Legal Ivory Trade: It Will Lead to More Killing of Elephants
Proponents of easing the global ban on ivory are ignoring the fact that it was a legal market for ivory that pushed elephants toward extinction only a few decades ago. What’s needed now is not a legal ivory market, but better regulation and enforcement of the existing ban.
-
The Case for a Climate Goal Other Than Two Degrees Celsius
Scientists and climate negotiators have largely agreed that limiting global warming to no more than 2 degrees Celsius is an important goal. But political scientist David Victor disagrees, arguing that the benchmark is too simplistic and should be abandoned in favor of other indicators.

With the Boom in Oil and Gas, Pipelines Proliferate in the U.S.
The rise of U.S. oil and gas production has spurred a dramatic expansion of the nation's pipeline infrastructure. As the lines reach into new communities and affect more property owners, concerns over the environmental impacts are growing.

He’s Still Bullish on Hybrids, But Skeptical of Electric Cars
Former Toyota executive Bill Reinert has long been dubious about the potential of electric cars. In an interview with Yale Environment 360, he talks about the promise of other technologies and about why he still sees hybrids as the best alternative to gasoline-powered vehicles.

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.

Oil Companies Quietly Prepare For a Future of Carbon Pricing
The major oil companies in the U.S. have not had to pay a price for the contribution their products make to climate change. But internal accounting by the companies, along with a host of other signs, suggest that may soon change — though the implications of a price on carbon are far from clear.

How Norway and Russia Made A Cod Fishery Live and Thrive
The prime cod fishing grounds of North America have been depleted or wiped out by overfishing and poor management. But in Arctic waters, Norway and Russia are working cooperatively to sustain a highly productive — and profitable — cod fishery.
-
Can Carbon Capture Technology Be Part of the Climate Solution?
Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels.

The Case for a Moratorium On Tar Sands Development
Ecologist Wendy Palen was one of a group of scientists who recently called for a moratorium on new development of Alberta’s tar sands. In a Yale Environment 360 interview, she talks about why Canada and the U.S. need to reconsider the tar sands as part of a long-term energy policy.

How Drones Are Emerging As Valuable Conservation Tool
Lian Pin Koh believes drones can be a key part of conservation efforts, particularly in remote regions. In a Yale Environment 360 interview, he talks about how his project, ConservationDrones, is promoting the use of drones for everything from counting orangutans to stopping poaching.

A New Frontier for Fracking: Drilling Near the Arctic Circle
Hydraulic fracturing is about to move into the Canadian Arctic, with companies exploring the region's rich shale oil deposits. But many indigenous people and conservationists have serious concerns about the impact of fracking in more fragile northern environments.

As Small Hydropower Expands, So Does Caution on Its Impacts
Small hydropower projects have the potential to bring electricity to millions of people now living off the grid. But experts warn that planners must carefully consider the cumulative effects of constructing too many small dams in a single watershed.

The Soil Pollution Crisis in China: A Cleanup Presents Daunting Challenge
Chinese officials are only starting to come to grips with the severity and extent of the soil pollution that has contaminated vast areas of the nation’s farm fields — by one estimate more than 8 percent of China’s arable land. But one thing is already clear: The cost and complexity of any remediation efforts will be enormous.
