Forests help reduce global warming in more ways than one

Trees are often touted as bulwarks against climate change for their capacity to sequester carbon, but that’s just one part of the story.

How did we get here? The roots and impacts of the climate crisis

Over the last century and a half, scientists have built a strong case for the roots and impacts of human-caused climate change.

A UN report shows climate change’s escalating toll on people and nature

The latest United Nations' IPCC climate change report underscores the urgent need for action to avoid the worst consequences of global warming.

Tech

Materials of the last century shaped modern life, but at a price

From our homes and cities to our electronics and clothing, the stuff of daily life is dramatically different from decades ago.

Animals

50 years ago, scientists were genetically modifying mosquitoes

In 1971, scientists turned to genetics to control disease-spreading mosquitoes without DDT. Today, there are a variety of pesticide-free methods.

Climate

Wildfire smoke may ramp up toxic ozone production in cities

A new study reveals how wildfire smoke produces toxic ozone and how urban air pollution could exacerbate the problem.

Plants

Invasive grasses are taking over the American West’s sea of sagebrush

Cheatgrass and other invasive plants are expanding rapidly in the western United States, putting more places at risk for wildfires.

Climate

Climate change could make Virginia’s Tangier Island uninhabitable by 2051

Tangier Island could be lost to rising seas sooner than previously realized. Whether to save the island or move its residents remains undecided.

Environment

Corals may store a surprising amount of microplastics in their skeletons

In tropical waters, coral reefs may be a “sink” for tiny bits of plastic debris. It’s unclear how corals’ trash pickup might affect reef health.

Environment

50 years ago, corporate greenwashing was well under way

Concerns about companies distorting their environmental record are nothing new. Environmental ads were flagged as deceptive back in 1971.

Chemistry

This eco-friendly glitter gets its color from plants, not plastic

Using cellulose extracted from wood pulp, researchers have created a greener alternative to traditional glitter.

Agriculture

Potty-trained cattle could help reduce pollution

About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, researchers say.
