After the Great Quake, Living with Earth’s Uncertainty
The Japanese earthquake and tsunami remind us that we exist in geologic time and in a world where catastrophic events beyond our predicting may occur. These events — and the growing specter of climate change — show how precariously we exist on the surface of a volatile planet.

In Aeolus Cave, A Search for the Vanishing Bats of the Northeast
When wildlife biologists ventured into a Vermont cave this month, they found disturbing evidence that white-nose syndrome was continuing to take its toll on once-abundant bat populations. But the question remains: What can be done to halt the spread of this still-mysterious ailment?

Tracking the Destructive Power of the Pacific Ocean’s Tsunamis
The devastating tsunami in northeastern Japan is only one of many that have battered Japan over the eons. In an interview with Yale Environment 360, tsunami and earthquake expert Lori Dengler describes the historic and paleological record of tsunamis across the Pacific, and what it may mean in the future for Japan and the western United States.

Agribusiness Boom Threatens Key African Wildlife Migration
The Ethiopian region of Gambella is home to Africa’s second-largest mammal migration, with more than a million endangered antelope and other animals moving through its grasslands. But the government has now leased vast tracts to foreign agribusinesses who are planning huge farms on land designated a national park.

‘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.

Climate’s Strong Fingerprint In Global Cholera Outbreaks
For decades, deadly outbreaks of cholera were attributed to the spread of disease through poor sanitation. But recent research demonstrates how closely cholera is tied to environmental and hydrological factors and to weather patterns — all of which may lead to more frequent cholera outbreaks as the world warms.

Arctic Roamers: The Move of Southern Species into Far North
Grizzly bears mating with polar bears. Red foxes out-competing Arctic foxes. Exotic diseases making their way into once-isolated polar realms. These are just some of the worrisome phenomena now occurring as Arctic temperatures soar and the Arctic Ocean, a once-impermeable barrier, melts.

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.

A Fierce Advocate for Grizzlies Sees Warning Signs for the Bear
Doug Peacock has been tireless defender of the Yellowstone grizzly for decades, but he believes the bear may now be facing its toughest threat yet. In an interview with Yale Environment 360, Peacock talks about the insect infestation that is destroying a key food source for grizzlies and recalls some of his closest encounters with the bears.

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.

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.

A Veteran of the Climate Wars Reflects On U.S. Failure to Act
One of the many casualties of the recent U.S. elections was Congressman Rick Boucher, a Virginia Democrat who played a key role in passage of cap-and-trade legislation by the House of Representatives. In an interview with Yale Environment 360, Boucher discusses the bitter failure of the Senate to pass a climate bill and future prospects for tackling global warming.

As the Arctic Ocean Melts, A Refuge Plan for the Polar Bear
With the Arctic Ocean heading toward a largely ice-free state in summer, scientists are looking for areas that may help preserve ice-dependent creatures. In an interview with Yale Environment 360, geologist Stephanie Pfirman talks about the need for a refuge north of Canada and Greenland that researchers say could be a kind of Noah’s Ark in the age of global warming.

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.

‘Perverse’ Carbon Payments Send Flood of Money to China
To offset their own carbon emissions, European companies have been overpaying China to incinerate a powerful greenhouse gas known as hfc 23. And in a bizarre twist, those payments have spurred the manufacture of a harmful refrigerant that is being smuggled into the U.S. and used illegally.

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.

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.
