Although it may seem simple, measuring rainfall worldwide has proven to be a difficult job for scientists. But a recently launched satellite is set to change that, providing data that could help in understanding whether global rainfall really is increasing as the planet warms.

Sci­en­tists Charles H. Greene, of Cor­nell Uni­ver­sity, and Daniel M. Kam­men, of the Uni­ver­sity of Cal­i­for­nia, Berke­ley, offer this com­men­tary on the recent Yale Envi­ron­ment 360 Point/Counterpoint arti­cles by Bob Massie and Robert N. Stavins on the fos­sil fuel divest­ment movement.

A sophisticated and challenging experiment in Antarctica is the latest effort to study ocean acidification in the polar regions, where frigid waters are expected to feel most acutely the ecological impacts of acidic conditions not seen in millions of years.

The mining of Canada’s tar sands has destroyed large areas of sensitive wetlands in Alberta. Oil sands companies have vowed to reclaim this land, but little restoration has occurred so far and many scientists say it is virtually impossible to rebuild these complex ecosystems.

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.

Student and activist groups have been urging universities to take a stand against climate change by divesting from companies that produce oil, natural gas, or coal. In a Yale Environment 360 debate, activist Bob Massie makes the case for divestment as a necessary tool in pushing for action on climate, while economist Robert Stavins argues it would be merely symbolic and have little effect.

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.

For six decades, writer Wendell Berry has spoken out in defense of local agriculture, rural communities, and the importance of caring for the land. In an interview with Yale Environment 360, he talks about his Kentucky farm, his activism, and why he remains hopeful for the future.

The degradation of soils from unsustainable agriculture and other development has released billions of tons of carbon into the atmosphere. But new research shows how effective land restoration could play a major role in sequestering CO2 and slowing climate change.

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.

Scientists are trying to understand if the unusual weather in the Northern Hemisphere this winter — from record heat in Alaska to unprecedented flooding in Britain — is linked to climate change. One thing seems clear: Shifts in the jet stream play a key role and could become even more disruptive as the world warms.

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.

In the last year, the U.S. government and nonprofits have put a spotlight on the illegal poaching of Africa’s elephants and Asia’s insatiable demand for ivory. But the media coverage has ignored a dirty secret: The U.S. has its own large ivory trade that has not been adequately regulated.

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 a sharp decline in pollinating insects, farmers are being encouraged to grow flowering plants that can support these important insects. It’s a fledgling movement that could help restore the pollinators that are essential for world food production.

A new strategy of granting animals “personhood” under the law is being advanced by some in academia and the animal rights movement. But this approach fails to address the fundamental truth that all species have an equal right to their own existence.
