In Japan’s Managed Landscape, a Struggle to Save the Bears
Although it is a heavily urbanized nation, fully two-thirds of Japan remains woodlands. Yet many of the forests are timber plantations inhospitable to wildlife, especially black bears, which are struggling to survive in one of the most densely populated countries on Earth.

Geoengineering the Planet: The Possibilities and the Pitfalls
Interfering with the Earth’s climate system to counteract global warming is a controversial concept. But in an interview with Yale Environment 360, climate scientist Ken Caldeira talks about why he believes the world needs to better understand which geoengineering schemes might work and which are fantasy — or worse.

The Economic Case for Slashing Carbon Emissions
Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.

The Spread of New Diseases and the Climate Connection
As humans increasingly encroach on forested lands and as temperatures rise, the transmission of disease from animals and insects to people is growing. Now a new field, known as “conservation medicine,” is exploring how ecosystem disturbance and changing interactions between wildlife and humans can lead to the spread of new pathogens.

The Other Inconvenient Truth: The Crisis in Global Land Use
As the international community focuses on climate change as the great challenge of our era, it is ignoring another looming problem — the global crisis in land use. With agricultural practices already causing massive ecological impact, the world must now find new ways to feed its burgeoning population and launch a "Greener" Revolution.

Provocative New Study Warns of Crossing Planetary Boundaries
The Earth has nine biophysical thresholds beyond which it cannot be pushed without disastrous consequences, the authors of a new paper in the journal Nature report. Ominously, these scientists say, we have already moved past three of these tipping points.

Korea’s Four Rivers Project: Economic Boost or Boondoggle?
The natural landscape of South Korea has been largely re-engineered, with nearly every river damned or forced into concrete channels. Now the government is reviving plans for a mammoth water project that would dredge and develop hundreds more miles of waterways and put added stress on the country's remaining wildlife.

Why I Still Oppose Genetically Modified Crops
Introduced more than a decade ago, genetically modified crops are now planted on millions of acres throughout the world. But the fundamental questions about them remain — both about their safety and their long-term impact on global food security and the environment.

The Great Paradox of China: Green Energy and Black Skies
China is on its way to becoming the world’s largest producer of renewable energy, yet it remains one of the most polluted countries on earth. A year after the Beijing Olympics, economic and political forces are combining to make China simultaneously a leader in alternative energy — and in dirty water and air.

The Folly of ‘Magical Solutions’ for Targeting Carbon Emissions
Setting unattainable emissions targets is not a policy — it’s an act of wishful thinking, argues one political scientist. Instead, governments and society should focus money and attention on workable solutions for improving energy efficiency and de-carbonizing our economies.

Report Gives Sobering View of Warming’s Impact on U.S.
A new U.S. government report paints a disturbing picture of the current and future effects of climate change and offers a glimpse of what the nation’s climate will be like by century’s end.

With the Clearing of Forests, Baby Orangutans Are Marooned
As Borneo's rain forests are razed for oil palm plantations, wildlife centers are taking in more and more orphaned orangutans and preparing them for reintroduction into the wild. But the endangered primates now face a new threat — there is not enough habitat where they can be returned.

A Plea to President Obama: End Mountaintop Coal Mining
Tighter restrictions on mountaintop removal mining are simply not enough. Instead, a leading climate scientist argues, the Obama administration must prohibit this destructive practice, which is devastating vast stretches of Appalachia.

The Damming of the Mekong: Major Blow to an Epic River
The Mekong has long flowed freely, supporting one of the world’s great inland fisheries. But China is now building a series of dams on the 2,800-mile river that will restrict its natural flow and threaten the sustenance of tens of millions of Southeast Asians.

The Challenge of Copenhagen: Bridging the U.S.-China Divide
The United States powered its rise to affluence with fossil fuels, and China resents being told it should not be free to do the same. So as negotiators prepare for crucial climate talks this December, the prospects for reaching agreement remain far from certain.

Putting a Price on Carbon: An Emissions Cap or a Tax?
The days of freely dumping greenhouse gases into the atmosphere are coming to an end, but how best to price carbon emissions remains in dispute. As the U.S. Congress debates the issue, Yale Environment 360 asked eight experts to discuss the merits of a cap-and-trade system versus a carbon tax.

Using Peer Pressure as a Tool to Promote Greener Choices
Environmentalists, utilities, and green businesses are turning to behavioral economics to find innovative ways of influencing people to do the right thing when it comes to the environment. Is this approach really good for the planet or just a fad?
-
Consumption Dwarfs Population as Main Environmental Threat
It's overconsumption, not population growth, that is the fundamental problem: By almost any measure, a small portion of the world's people — those in the affluent, developed world — use up most of the Earth's resources and produce most of its greenhouse gas emissions.

China’s Grand Plans for Eco-Cities Now Lie Abandoned
Mostly conceived by international architects, China’s eco-cities were intended to be models of green urban design. But the planning was done with little awareness of how local people lived, and the much-touted projects have largely been scrapped.

Despite Economy, the Prospects for Green Energy Remain Strong
The economic downturn need not halt the development of green energy. In fact, with renewable technologies improving dramatically and new U.S. policies emerging, continued progress toward an energy revolution is inevitable.

Finding New Species: The Golden Age of Discovery
Aided by new access to remote regions, researchers have been discovering new species at a record pace — 16,969 in 2006 alone. The challenge now is to preserve threatened ecosystems before these species, and others yet unknown, are lost.
