The Paris climate conference set the ambitious goal of finding ways to limit global warming to 1.5 degrees Celsius, rather than the previous threshold of 2 degrees. But what would be the difference between a 1.5 and 2 degree world? And how realistic is such a target?

The revisionist effort to increase the percentage of ethanol blended with U.S. gasoline continues to ignore the major environmental impacts of growing corn for fuel and how it inevitably leads to higher prices for this staple food crop. It remains a bad idea whose time has passed.

Physicist Klaus Lackner has long advocated deploying devices that extract carbon dioxide from the atmosphere to combat climate change. Now, as emissions keep soaring, Lackner says in a Yale Environment 360 interview that such “air capture” approaches may be our last best hope.

As the world moves to slash CO2 emissions, the shipping and aviation sectors have managed to remain on the sidelines. But the pressure is now on these two major polluting industries to start controlling their emissions at last.

Facing one of the worst droughts in memory, South Africa’s leaders have doubled down on their support of the water-intensive coal industry. But clean energy advocates say the smartest move would be to back the country’s burgeoning wind and solar power sectors.

Winning protected status for key natural areas and habitat has long been seen as the gold standard of conservation. But these gains are increasingly being compromised as governments redraw park boundaries to accommodate mining, logging, and other development.

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.

In the face of rising temperatures and worsening drought, the world’s repositories of agricultural seeds may hold the key to growing food under increasingly harsh conditions. But keeping these gene banks safe and viable is a complicated and expensive challenge.

Until recently, little was known about the extent of methane leaking from urban gas distribution pipes and its impact on global warming. But recent advances in detecting this potent greenhouse gas are pushing U.S. states to begin addressing this long-neglected problem.

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.

Subsistence hunters in the Arctic have long taken to the sea ice to hunt seals, whales, and polar bears. But now, as the ice disappears and soaring temperatures alter the life cycles and abundance of their prey, a growing number of indigenous communities are facing food shortages.

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.

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.

With the recent opening of a “bike highway,” Germany is taking the lead in Europe by starting to build a network of wide, dedicated bicycle thoroughfares designed to lure increasing numbers of commuters out of their cars and onto two wheels.

The U.S. Supreme Court order blocking President Obama’s plan to cut emissions from coal-burning power plants is an unprecedented step and one of the most environmentally harmful decisions ever made by the nation’s highest court.

Europe and the United States have very similar standards of living, but significantly different carbon footprints. Aerial photographer Alex MacLean documents this phenomenon in images that show how Northern Europe uses smart design and planning to reduce the amount of carbon it emits.

An unprecedented global wave of virulent fungal infections is decimating whole groups of animals — from salamanders and frogs, to snakes and bats. While scientists are still trying to understand the causes, they are pointing to intercontinental travel, the pet trade, and degraded habitat as likely factors.
