The draft of the latest report from the Intergovernmental Panel on Climate Change warns that the world faces serious risks from warming and that the poor are especially vulnerable. But it avoids the kinds of specific forecasts that have sparked controversy in the past.

Having universities divest from fossil fuels is a feel-good measure that would do nothing to address the problem of global climate change. Instead, we should be focusing on efforts to push for strong government action.

From forests in Queens to wetlands in China, planners and scientists are promoting a new approach that incorporates experiments into landscape restoration projects to determine what works to the long-term benefit of nature and what does not.

As an ambitious program in Colombia demonstrates, combining grazing and agriculture with tree cultivation can coax more food from each acre, boost farmers’ incomes, restore degraded landscapes, and make farmland more resilient to climate change.

Few companies have done as much damage to the world’s tropical forests as Asia Pulp & Paper. But under intense pressure from its customers and conservation groups, APP has embarked on a series of changes that could significantly reduce deforestation in Indonesia and serve as a model for forestry reform.

The emerging field of “energy scavenging” is drawing on a wide array of untapped energy sources — including radio waves, vibrations created by moving objects, and waste heat from computers or car exhaust systems — to generate electricity and boost efficiency.

With a massive dam under construction in Laos and other dams on the way, the Mekong River is facing a wave of hydroelectric projects that could profoundly alter the river’s ecology and disrupt the food supplies of millions of people in Southeast Asia.

With hydraulic fracturing for oil and gas continuing to proliferate across the U.S., scientists and environmental activists are raising questions about whether millions of gallons of contaminated drilling fluids could be threatening water supplies and human health.

As these photographs and illustrations show, architect David Waggonner has decided that the best way to protect low-lying New Orleans is to think about water in an entirely different way.

For decades, hazardous electronic waste from around the world has been processed in unsafe backyard recycling operations in Asia and Africa. Now, a small but growing movement is seeking to provide these informal collectors with incentives to sell e-waste to advanced recycling facilities.

With some species of Arctic birds experiencing steep drops in population and their prey also undergoing marked shifts, scientists are working to understand what role climate change is playing in these unfolding ecological transformations.

Research shows that biochar made from plant fodder and even chicken manure can be used to scrub mercury from power plant emissions and clean up polluted soil. The big question is whether biochar can be produced on a sufficiently large scale to slow or reverse global warming.

Powered by solar panels and biomass, microgrids are spreading slowly across India, where 300 million people live without electricity. But can these off-grid technologies be scaled-up to bring low-carbon power to tens of millions of people?

In a Yale Environment 360 interview, the outspoken executive director of Greenpeace discusses why his organization’s activists braved imprisonment in Russia to stop Arctic oil drilling and what needs to be done to make a sharp turn away from fossil fuels and toward a green energy economy.

Even if reviving extinct species is practical, it’s an awful idea. It would take resources away from saving endangered species and their habitats and would divert us from the critical work needed to protect the planet.

As the world becomes more urbanized, researchers and city managers from Baltimore to Britain are recognizing the importance of providing urban habitat that can support biodiversity. It just may be the start of an urban wildlife movement.

In Borneo's Danum Valley — one of the last, untouched forest reserves in a region ravaged by logging and oil palm cultivation — a team of international and Malaysian scientists is fighting to preserve an area of stunning biodiversity.

Photographer Peter Essick has traveled the world documenting the causes and consequences of climate change. In a Yale Environment 360 photo essay, we present a gallery of images Essick took while on assignment in Antarctica, Greenland, and other far-flung locales.

By encouraging the adoption of innovative architectural design and energy-saving technologies, Singapore has emerged as a model of green building in Asia — an important development in a region that is urbanizing more rapidly than any other in the world.

Although coal has dominated the South African electricity sector for decades, the country’s abundant solar and wind resources offer a promising renewable energy alternative. But entrenched political interests connected to the ruling party are fighting to expand coal’s role in the national economy.

As debate over the Keystone XL and other pipeline projects continues, crude oil from the Alberta tar sands and western U.S. oil fields is increasingly being hauled by railroad. Critics warn that this development poses a threat not only to the environment but to public safety.
