In an interview with Yale Environment 360, marine biologist Gretchen Hofmann discusses how well mollusks and other shell-building organisms might evolve to live in increasingly corrosive ocean conditions caused by soaring CO2 emissions.

Brown pelicans were removed from the U.S. Endangered Species List in 2009, in what was considered a major conservation success story. But a recent crash in Pacific Coast populations of sardines, the pelican’s prime food, is posing new threats to these oddly elegant birds.

Originating in Europe, \"nature-like\" fishways are now being constructed on some U.S. rivers where removing dams is not an option. Unlike traditional fish ladders, these passages use a natural approach aimed at significantly increasing once-abundant runs of migratory fish.

Congo's Virunga National Park has long been known for its mountain gorillas and for the lawless militias that operate there. But the recent shooting of the park warden and plans to begin oil exploration in the park have sparked concern about the future of this iconic World Heritage Site.

High-altitude neotropical ecosystems known as páramos are increasingly at risk in Colombia and elsewhere in South America as major mining companies seek to exploit rich deposits of gold and other minerals. Such projects, scientists warn, could have serious impacts on critical water supplies.

A recent study shows that a surprisingly large amount of the seafood sold in U.S. markets is caught illegally. In a series of actions over the last few months, governments and international regulators have started taking aim at stopping this illicit trade in contraband fish.

In its latest report, the UN's Intergovernmental Panel on Climate Change makes a strong case for a sharp increase in low-carbon energy production, especially solar and wind, and provides hope that this transformation can occur in time to hold off the worst impacts of global warming.

Conservation groups are mounting campaigns to persuade Vietnamese consumers that buying rhino horn is decidedly uncool. But such efforts are likely to succeed only as part of a broader initiative to crack down on an illicit trade that is decimating African rhino populations.

As global population soars, efforts to boost food production will inevitably be focused on the world’s tropical regions. Can this agricultural transformation be achieved without destroying the remaining tropical forests of Africa, South America, and Asia?

Scientists, engineers, and government regulators are increasingly turning their attention to solving one of the chief environmental problems associated with fracking for natural gas and oil significant leaks of methane, a potent greenhouse gas.

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.

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.

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.
