‘Fracking’ Comes to Europe, Sparking Rising Controversy
As concerns grow in the U.S. about the environmental impact of hydraulic fracturing, or “fracking,” to extract natural gas from shale, companies have set their sights on Europe and its abundant reserves of this “unconventional” gas. But from Britain to Poland, critics warn of the potentially high environmental cost of this looming energy boom.

How Fisheries Can Gain From The Lessons of Sustainable Food
As agriculture and energy production have made strides toward becoming more sustainable, the world’s fisheries have lagged behind. But restoring our beleaguered oceans to health will require an emphasis on diversification and conservation — and a more sensible mix of fishing practices.

Growth of Wood Biomass Power Stokes Concern on Emissions
Across the U.S., companies are planning scores of projects to burn trees and wood waste to produce electricity, claiming such biomass plants can be carbon-neutral. But critics contend that combusting wood is not really a form of green energy and are urging a go-slow approach until clear guidelines can be established.

Why Does Energy Efficiency’s Promise Remain Unfulfilled?
Among the many measures the world can take to wean itself off fossil fuels, few match the benefits of making homes, business, and cars more energy-efficient. But financial and psychological barriers have kept individuals, businesses, and governments from realizing efficiency’s great potential.

In Novel Approach to Fisheries, Fishermen Manage the Catch
An increasingly productive way of restoring fisheries is based on the counter-intuitive concept of allowing fishermen to take charge of their own catch. But the success of this growing movement depends heavily on a strong leader who will look out not only for the fishermen, but for the resource itself.

Living in the Anthropocene: Toward a New Global Ethos
A decade ago, Nobel Prize-winning scientist Paul Crutzen first suggested we were living in the “Anthropocene,” a new geological epoch in which humans had altered the planet. Now, in an article for Yale Environment 360, Crutzen and a coauthor explain why adopting this term could help transform the perception of our role as stewards of the Earth.

Green Energy’s Big Challenge: The Daunting Task of Scaling Up
To shift the global economy from fossil fuels to renewable energy will require the construction of wind, solar, nuclear, and other installations on a vast scale, significantly altering the face of the planet. Can these new forms of energy approach the scale needed to meet the world’s energy demands?

Can We Trust Climate Models? Increasingly, the Answer is ‘Yes’
Forecasting what the Earth’s climate might look like a century from now has long presented a huge challenge to climate scientists. But better understanding of the climate system, improved observations of the current climate, and rapidly improving computing power are slowly leading to more reliable methods.

Refilling the Carbon Sink: Biochar’s Potential and Pitfalls
The idea of creating biochar by burning organic waste in oxygen-free chambers — and then burying it — is being touted as a way to cool the planet. But while it already is being produced on a small scale, biochar’s proponents and detractors are sharply divided over whether it can help slow global warming.
