A 2021 pledge by more than 100 nations to cut methane emissions from anthropogenic sources 30 percent by 2030 might not slow global warming as much as projected, as new research shows that feedbacks in the climate system are boosting methane emissions from natural sources, especially tropical wetlands.

On a Southern California spring morning in 1973, a tanker truck driver jackknifed his rig and dumped the agricultural fumigant he was transporting onto a city street. A Los Angeles Fire Department emergency response team spent four hours cleaning up the chemical, 1,3-dichloropropene, or 1,3-D, a fumigant sold as Telone that farmers use to kill nematodes and other soil-dwelling organisms before planting.

Miles to Go: The third in an ongoing series Inside Climate News fellow Bing Lin is reporting from the Pacific Crest Trail in Northern California. Over the course of a 500-mile-hike, the series is exploring the impacts of climate change on the trail and what outdoor recreation can teach society about sustainability, adaptation and coexistence in a warming world.

It started life in the Indian Ocean, hitched a ride to the Mediterranean through the Suez Canal and kept pushing west. Now the fast-growing seagrass known as Halophila stipulacea is expanding in the Caribbean as waters warm, outcompeting important native grasses. It’s the definition of an invasive species.

In 2019, Laura Schifter’s phone buzzed with a message: “Only 11 Years Left to Prevent Irreversible Damage From Climate Change.” As she lifted her eyes from her phone back to her three children playing in her basement, she knew she had to fight for them.

The Never Summer Mountains tower almost 13,000 feet above sea level on the west side of Rocky Mountain National Park, the regal headwaters of the Colorado River. Snowmelt and rainfall trickle southwest from the peaks through jumbles of scree and colorful deposits of silicic rock, formed some 27 to 29 million years ago, then plunge into Gore Canyon. There, the river gallops downstream, absorbing other tributaries from Arizona, New Mexico, Utah and Wyoming on its way to California. More than 40 million people from seven states and Mexico depend on water from the Colorado River Basin to drink, irrigate crops, generate electricity and recreate, a demand that is greater than the river system can bear.
