Thinking the Unthinkable: Engineering Earth’s Climate
A U.S. panel has called for a concerted effort to study proposals to manipulate the climate to slow global warming — a heretical notion among some environmentalists. In an interview with Yale Environment 360, Jane C. S. Long, the group’s chairwoman, explains why we need to know more about the possibilities and perils of geoengineering.

Can Wildlife Corridors Heal Fragmented Landscapes?
Conservationists have long called for creating ecological corridors that would enable large mammals and other wildlife to roam more freely across an increasingly developed planet. But now scientists are taking a closer look at just how well these corridors are working and what role they might play in a warming world.

The Crucial Role of Predators: A New Perspective on Ecology
Scientists have recently begun to understand the vital role played by top predators in ecosystems and the profound impacts that occur when those predators are wiped out. Now, researchers are citing new evidence that shows the importance of lions, wolves, sharks, and other creatures at the top of the food chain.

A Huge Oil Palm Plantation Puts African Rainforest at Risk
As global agricultural companies turn to Africa, a U.S. firm is planning a massive oil palm plantation in Cameroon that it says will benefit local villagers. But critics argue that the project would destroy some of the key remaining forests in the West African nation and threaten species-rich reserves.

Saving Ancient Walnut Forests In the Valleys of Central Asia
The former Soviet republic of Kyrgyzstan is home to some of the world’s largest remaining forests of walnut and wild fruit trees. In an effort to sustainably manage this global resource, an international project has focused on ending Soviet-style management and giving power — and a profit incentive — to local farmers.

The Long Strange Journey Of Earth’s Traveling Microbes
Airborne microbes can travel thousands of miles and high into the stratosphere. Now scientists are beginning to understand the possible role of these microbes — such as bacteria, fungal spores, and tiny algae — in creating clouds, causing rain, spreading disease, and even changing climate.

A Solar Panel on Every Roof? In U.S., Still a Distant Dream
Daunted by high up-front costs, U.S. homeowners continue to shy away from residential solar power systems, even as utility-scale solar projects are taking off. But with do-it-yourself kits and other innovative installation approaches now on the market, residential solar is having modest growth.

Assessing Emerging Challenges In U.S. Environmental Health
From understanding the cumulative impacts of widely used chemicals to preparing for life in a warming world, a host of environmental health issues now face medical experts. In an interview with Yale Environment 360, Lynn Goldman, dean of the George Washington University School of Public Health and Health Services, talks about meeting the challenges.

On Lake Taihu, China Moves To Battle Massive Algae Blooms
For two decades, the once-scenic Lake Taihu in eastern China has been choked with devastating algae blooms that have threatened drinking water for millions. Now, in a move that could provide lessons for other huge lakes worldwide, China is taking steps to restore Taihu’s ecological balance.

The World at 7 Billion: Can We Stop Growing Now?
With global population expected to surpass 7 billion people this year, the staggering impact on an overtaxed planet is becoming more and more evident. A two-pronged response is imperative: empower women to make their own decisions on childbearing and rein in our excessive consumption of resources.

On Biking, Why Can’t the U.S. Learn Lessons from Europe?
Building bike paths alone will not get people out of their cars in the U.S. and onto bicycles. To create a thriving bike culture in America’s cities, people must begin to view bicycling as Europeans do — not just as a way of exercising, but as a serious form of urban mass transportation.

A World Centered on Sea Ice Is Changing Swiftly at the Poles
For eons, the polar marine food chain has been closely linked to the seasonal formation and retreat of sea ice. Now, as that ice rapidly melts in the Arctic and along the Antarctic Peninsula, this intricate web of life is undergoing major shifts, benefiting some creatures and putting others at risk.

New Model for Aquaculture Takes Hold Far from the Sea
With ever-greater quantities of seafood coming from aquaculture operations, some companies are working on ways to reduce the environmental impact of fish farming. In an interview with Yale Environment 360, Josh Goldman of Australis Aquaculture talks about his highly praised closed-containment fish farm in Massachusetts.

Forum: Just How Safe Is ‘Fracking’ of Natural Gas?
New technologies for freeing natural gas from underground shale formations have led to a hydraulic fracturing boom across the U.S. that is now spreading to other countries. In a Yale Environment 360 forum, eight experts discuss whether “fracking” can be done without serious harm to water and air quality and what environmental safeguards may be needed. -
The Unfulfilled Promise of the World’s Marine Protected Areas
Biologists and conservationists maintain that establishing marine reserves — areas where fishing is off-limits or severely restricted — offers the best hope for recovery for our overstressed oceans. So why is such a small area of the world's oceans protected?

As Arctic Sea Ice Retreats, Storms Take Toll on the Land
For millennia, the blanket of ice covering the Arctic Ocean protected the shore from damaging storms. But as that ice buffer disappears, increasingly powerful storm surges are eroding the coastline and sending walls of seawater inland, devastating Arctic ecosystems that support abundant wildlife.

Forum: Is Extreme Weather Linked to Global Warming?
In the past year, the world has seen a large number of extreme weather events, from the Russian heat wave last summer, to the severe flooding in Pakistan, to the recent tornadoes in the U.S. In a Yale Environment 360 forum, a panel of experts weighs in on whether the wild weather may be tied to increasing global temperatures.

Off the Pedestal: Creating a New Vision of Economic Growth
The idea of economic growth as an unquestioned force for good is ingrained in the American psyche. But a longtime environmental leader argues it’s time for the U.S. to reinvent its economy into one that focuses on sustaining communities, family life, and the natural world.

Oyster Aquaculture Offers Hope for Louisiana Fishery and the Gulf
Last year’s oil spill in the Gulf of Mexico severely damaged Louisiana’s oyster beds, one of the world’s last thriving wild oyster fisheries. In a Yale Environment 360 video, journalist Jon Brand reports on an experimental oyster farm in Louisiana that offers hope for a smoother recovery for the Gulf’s oysters and its oystermen.

Germany’s Unlikely Champion Of a Radical Green Energy Path
The disaster at the Fukushima plant in Japan convinced German Chancellor Angela Merkel that nuclear power would never again be a viable option for her country. Now Merkel has embarked on the world’s most ambitious plan to power an industrial economy on renewable sources of energy.

What’s With the Weather? Is Climate Change to Blame?
One of the thorniest questions facing climate scientists is whether human-induced climate change is leading to more heat waves, floods, and extreme weather events. Now, employing increasingly sophisticated methods of studying weather extremes, climatologists say they are closer to answering that key question.
