Panel Chief on the Gulf Spill: Complacency Led to Disaster
William Reilly led the national commission that investigated the Deepwater Horizon oil spill and says he was struck by the totally inadequate response plans that were in place. In an interview with Yale Environment 360, he talks about why it’s crucial to carry out the reforms needed to prevent future disasters.

Massive Outbreak of Jellyfish Could Spell Trouble for Fisheries
The world’s oceans have been experiencing enormous blooms of jellyfish, apparently caused by overfishing, declining water quality, and rising sea temperatures. Now, scientists are trying to determine if these outbreaks could represent a “new normal” in which jellyfish increasingly supplant fish.

Calculating the True Cost Of Global Climate Change
Researchers disagree about what the economic costs of climate change will be over the coming decades. But the answer to that question is fundamental in deciding how urgent it is to take action to reduce emissions.

In China, a New Transparency On Government Pollution Data
The Chinese government has begun to make environmental records available to the public, empowering green groups and citizens as they try to force factories — and the Western companies they supply — to comply with the law.

Did Cancun Prove the UN Irrelevant in Tackling Climate?
The Cancun conference is being credited with keeping international climate talks alive. But the real potential for bringing emissions under control may lie in a Plan B, with nations acting on their own in moving toward a low-carbon economy.

Is the End in Sight for The World’s Coral Reefs?
It is a difficult idea to fathom. But the science is clear: Unless we change the way we live, the Earth's coral reefs will be utterly destroyed within our children's lifetimes.

The Warming of Antarctica: A Citadel of Ice Begins to Melt
The fringes of the coldest continent are starting to feel the heat, with the northern Antarctic Peninsula warming faster than virtually any place on Earth. These rapidly rising temperatures represent the first breach in the enormous frozen dome that holds 90 percent of the world’s ice.

As Shark Slaughter Continues, A Defender Targets Fin Trade
As the economies of China and other Asian nations have boomed, demand for shark fins — a prized delicacy — has soared, leading to severe overfishing of many shark species. In an interview with Yale Environment 360, shark conservationist Sonja Fordham talks about the battle to save one of the world’s most magnificent fish.

China Turns to Biogas to Ease Impact of Factory Farms
In China, millions of tons of waste from livestock farms are causing severe water pollution and massive emissions of methane. Now, some large livestock operators are turning to biogas fuel production in hopes of creating “ecological” factory farms.

Hatch-22: The Problem with The Pacific Salmon Resurgence
The number of salmon in the Pacific Ocean is twice what it was 50 years ago. But there is a downside to this bounty, as growing numbers of hatchery-produced salmon are flooding the Pacific and making it hard for threatened wild salmon species to find enough food to survive.

A Positive Path for Meeting The Global Climate Challenge
Climate policies that require public sacrifice and limiting economic growth are doomed to failure. To succeed, policies to reduce emissions must promise real benefits and must help make clean energy cheaper.

Forging a Landmark Agreement To Save Canada’s Boreal Forest
Last spring, conservation groups and timber companies signed an historic agreement to protect a large swath of Canada’s boreal forest. In an interview with Yale Environment 360, the Pew Environment Group's Steven E. Kallick, a key player in the agreement, explains why the accord is integral to a larger plan to eventually preserve half of Canada’s extensive boreal forests.

Exploring the Links Between Hurricanes and Ocean Warming
One of the more contentious issues facing climate scientists is whether rising ocean temperatures will cause more frequent and powerful hurricanes. In an interview with Yale Environment 360, Kerry Emanuel, of the Massachusetts Institute of Technology, says that amid the uncertainty, one thing seems likely: an increase in the most potent — and destructive — storms.

A Steady, Steep Decline for The Lowly, Uncharismatic Eel
The freshwater eel, which spawns in the middle of the ocean, was once abundant in much of the world. But the proliferation of dams, coastal development, and overfishing have drastically reduced eel populations, with few defenders coming to the aid of these fascinating — though still not fully understood — creatures.

On China’s Beleaguered Yangtze, A Push to Save Surviving Species
The Yangtze has been carved up by dams, used as an open sewer, and subjected to decades of overfishing. Now, Chinese scientists — alarmed by the disappearance of the Yangtze river dolphin and other creatures — are calling for a 10-year moratorium on fishing in the world’s third-longest river.

The Legacy of the Gulf Spill: What to Expect for the Future?
The Gulf of Mexico’s capacity to recover from previous environmental assaults — especially the 1979 Ixtoc explosion — provides encouragement about the prospects for its post-Deepwater future. But scientists remain worried about the BP spill's long-term effects on the health of the Gulf and its sea life.

A Looming Oxygen Crisis and Its Impact on World’s Oceans
As warming intensifies, scientists warn, the oxygen content of oceans across the planet could be more and more diminished, with serious consequences for the future of fish and other sea life.

Growing Shortages of Water Threaten China’s Development
With 20 percent of the world’s population but just 7 percent of its available freshwater, China faces serious water shortages as its economy booms and urbanization increases. The government is planning massive water diversion projects, but environmentalists say conservation — especially in the wasteful agricultural sector — is the key.

Tracking the Himalaya’s Melting Glaciers
Unearthing photographs of the Himalaya dating back more than a century, mountaineer and filmmaker David Breashears has assembled a powerful visual record of the rapid retreat of the region’s glaciers. By comparing archival photographs from such renowned explorers as George Mallory to photographs taken in the past three years, Breashears has documented the steady disappearance of these great rivers of ice, whose melting will eventually threaten the water supplies of hundreds of millions of people across Asia.

For Hudson Bay Polar Bears, The End is Already in Sight
The polar bear has long been a symbol of the damage wrought by global warming, but now biologist Andrew Derocher and his colleagues have calculated how long one southerly population can hold out. Their answer? No more than a few decades, as the bears’ decline closely tracks that of the Arctic’s disappearing sea ice.

High Above the Earth, Satellites Track Melting Ice
The surest sign of a warming Earth is the steady melting of its ice zones, from disappearing sea ice in the Arctic to shrinking glaciers worldwide. Now, scientists are using increasingly sophisticated satellite technology to measure the extent, thickness, and height of ice, assembling an essential picture of a planet in transition.
