For climate scientist Kim Cobb, this year’s massive bleaching of coral reefs is providing sobering insights into the impacts of global warming. Yale Environment 360 talked with Cobb about the bleaching events and the push to make reefs more resilient to rising temperatures.

The 'ōhi'a is Hawaii’s iconic tree, a keystone species that maintains healthy watersheds and provides habitat for numerous endangered birds. But a virulent fungal disease, possibly related to a warmer, drier climate, is now felling the island’s cherished 'ōhi'a forests.

Marine scientist Christopher Clark has spent his career listening in on what he calls “the song of life” in the world’s oceans. In an interview with Yale Environment 360, he explains how these marine habitats are under assault from extreme—but preventable—noise pollution.

Researchers are only beginning to understand the complexities of the microbes in the earth’s soil and the role they play in fostering healthy ecosystems. Now, climate change is threatening to disrupt these microbes and the key functions they provide.

Low gasoline prices and continuing performance issues have slowed the growth of electric car sales. But that has not stymied progress in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight giants like FedEx.

If the world is to have another Green Revolution to feed its soaring population, it must be far more sustainable than the first one. That means finding ways to boost yields with less fertilizer and rethinking the way food is distributed.

Angel Garcia, of Young Conservatives for Energy Reform, is working to persuade Republicans about the need for renewable energy. In an interview with Yale Environment 360, he explains why his group avoids mentioning climate change when it makes its pitch to conservatives

As part of India's modernization program, Prime Minister Narenda Modi has called for doubling the nation’s coal production by 2020.

In the wake of the Paris climate agreement, developing countries find themselves in need of analysts capable of monitoring their emissions. It’s a complex task, but organizations are stepping in with online courses to train these new green accountants.

Agribusinesses are increasingly using computer databases to enable farmers to grow crops more efficiently and with less environmental impact. Experts hope this data, detailing everything from water use to crop yields, can also help the developing world grow more food.

Development pressures are threatening Istanbul's centuries-old gardens, which have produced food for the city's markets since Byzantine times. A coalition of gardeners and environmentalists is fighting to preserve them.

A group of small-scale Japanese fishermen are waging an increasingly public struggle against industrial fishing fleets that are using sonar and huge nets to scoop up massive catches of spawning Pacific bluefin tuna.

As India looks to bring electricity to the quarter of its population still without it, nonprofit groups are increasingly turning to solar microgrids to provide power to the nation’s villages. But the initiatives so far have faced major challenges.

An increasing number of nonprofit organizations are relying on satellite imagery to monitor environmental degradation. Chief among them is SkyTruth, which has used this data to expose the extent of the BP oil spill, uncover mining damage, and track illegal fishing worldwide.
