Don’t expect the U.S. Congress to take any action on climate change in the next four years. But by continuing to use its regulatory authority and working with the states, the Obama administration can make significant progress on reducing greenhouse gas emissions.

Conservation organizations are working with industry to try to make beef production more sustainable. But some are questioning whether green groups should be accepting funds from the beef industry or whether they should instead be urging consumers to stop eating beef.

Martha Schwartz, a professor at Harvard’s Graduate School of Design, explains in a Yale Environment 360 interview how creative landscape architecture can help cities become models of sustainability in a world facing daunting environmental challenges.

With the relationship between utilities and their customers changing in unprecedented ways, new companies are deploying vast amounts of data and social psychology techniques to try to persuade people to use less electricity in their homes.

The rapid development of Alberta’s tar sands has spawned a new proposal for a 731-mile pipeline that would transport oil to the British Columbia coast. The project is strongly opposed by conservationists and First Nations leaders, who fear the environmental risks it would bring.

The killing of rhinoceroses has escalated dramatically, especially in South Africa, which is home to 75 percent of the world’s rhino population. The slaughter is being orchestrated by brazen, highly organized gangs that smuggle the rhinos' horns to black markets in China and Southeast Asia.

With a new round of climate negotiations about to get underway, Christiana Figueres, head of the United Nations climate organization, explains in a Yale Environment 360 interview why, despite the obstacles, she thinks the world community is slowly inching its way toward an agreement.

No broad-based international agreement on sharing rivers currently exists, even though much of the world depends on water from rivers that flow through more than one nation. But that may be about to change, as two separate global river treaties are close to being approved.

Years of sanctions against Myanmar’s military regime helped protect its extensive wild lands. But as the country’s rulers relax their grip and welcome foreign investment, can the nation protect its forests and biodiversity while embracing development?

Climate change received scant attention in the election campaign. But with public concern about global warming growing in the wake of Hurricane Sandy, President Obama has an unprecedented opportunity to take bold action on climate and clean energy.

Given the failure of international climate negotiations, a tax on carbon consumption is the most effective way of lowering CO2 emissions. If nations are serious about addressing climate change, then they must pay for the carbon pollution caused by what they consume.

New York City had been gradually preparing for a world of rising seas and more powerful storms. But the devastation caused by Hurricane Sandy is now forcing officials to consider spending billions of dollars on storm protection, including a network of surge barriers.

For the past six years, photographer James Balog has deployed dozens of time-lapse cameras around the world to chronicle one of the starkest examples of global warming — melting glaciers. In a Yale Environment 360 interview, Balog talks about his passion to capture these vanishing landscapes.

Researchers have been documenting the deadly threat that fishing lines and ropes pose to large whales that become entangled in them. Now, new studies are pointing to another disturbing fact: the ensnared whales endure enormous pain and prolonged suffering.

Few creatures in the United States have come as close to extinction as the Mexican wolf, which was wiped out in the U.S. by 1970. Now, scientists and conservationists contend, federal officials are caving into political pressure and failing to implement a legally mandated reintroduction plan.

The concept of pricing ecosystem services and allowing them to be bought and sold has gained wide acceptance among conservationists in recent years. But does this approach merely obscure nature’s true value and put the natural world at even greater risk?

A host of startup companies are pursuing new technologies that they claim will soon lead to large-scale commercialization of biofuels made from algae. But questions remain about the viability and environmental benefits of what some of its developers are calling “green crude.”

Inadequate sewage systems and the lack of toilets in much of the developing world have created a major public health and environmental crisis. Now various innovators are promoting new kinds of toilets and technologies that use little or no water and recycle the waste.

In Guatemala’s vast Maya Biosphere Reserve, conservation groups are battling to preserve a unique rainforest now under threat from Mexican drug cartels, Salvadoran drug gangs, and Chinese-backed groups illegally logging prime tropical hardwoods.

Experts believe the next deadly human pandemic will almost certainly be a virus that spills over from wildlife to humans. The reasons why have a lot to do with the frenetic pace with which we are destroying wild places and disrupting ecosystems.
