Every day, two NASA space instruments known as the Orbiting Carbon Observatory-2 and -3 (OCO-2 and OCO-3) capture more than a million observations of sunlight reflecting off Earth's surface. Using the physics of how light travels through the air, an algorithm converts these raw data into atmospheric carbon dioxide (CO₂) concentrations.

Farming, dams and agricultural runoff are the biggest threats to freshwater biodiversity globally, with Europe and Northwest Africa the hardest-hit regions, McGill researchers have found.

Chocolate lovers may not realize it, but the future of one of the world's most popular foods is increasingly under pressure.

Flowers may look simple from the outside, but inside, they can create their own miniature environments.

NAYA PADAMPUR, Nepal - A spinning wheel whirs on a rooftop in Naya Padampur in south-central Nepal, sending ivory strands of yarn through Bin Maya Gurung's practiced fingers. Smile lines crinkle at the corners of her eyes as she works. Her limbs move in synchrony with the wheel, both integral parts of the machine that ensures her family's well-being. She's sitting at the top of a building that houses a wool spinning enterprise, which has blossomed in the years since she learned to spin wool in the early 2000s. It's one of many women-led microenterprises that have sprouted across the . . .

Tesla has launched a new referral program in the US that pays owners in Full Self-Driving (Supervised) instead of rewarding car sales. A referred owner gets one free month of FSD, and the referrer gets a free month or a $99 Tesla Credit if that person starts paying. At the same time, Tesla's Refer and Earn terms no longer list any vehicle as a qualifying purchase for buyer or referrer rewards. Buy a Tesla with a friend's code today and neither of you gets anything. more . . .

A group of U.S. lawmakers is urging Secretary of State Marco Rubio not to support Colombia's plans to restart aerial spraying of coca crops in the Amazon, warning of risks to human health and the environment. The Colombian government says spraying is needed to combat cocaine production and weaken armed groups, but critics argue the decades-old strategy has failed and could accelerate deforestation. The lawmakers are questioning Washington's potential involvement and calling for alternatives that protect rural communities and the rainforest. Despite decades of U.S.-backed counternarcotics . . .

Eroding coastlines, fisheries at risk, contaminants like PFAS – researchers from across Duke are innovating to solve these and other water-related issues.

KIT researchers and partners analyze caloric cooling technologies – Nature Review highlights progress, open questions, and pathways toward sustainable cooling systems.

A new modeling study, published in the journal Nature Climate Change, suggests that the East Antarctic Ice Sheet may be more resilient to extreme long-term warming than previously estimated.

In 2017, Omar Trujillo Santos was sitting in a small wooden boat holding a crocodile, its skin soft like a snake. He helped untie the reptile, a juvenile Morelet's crocodile, and carefully guided it into the dark water. It swam off to find a new home in the Alvarado Lagoons System in Veracruz, southeastern Mexico, completing the final phase of a mangrove restoration project. Studies suggest Mexico, a country rich in mangroves, has experienced the highest degree of mangrove loss in the Americas. Conservation and reforestation efforts seek to reverse this loss, yet many projects fail to . . .

Hydrofoils have an obvious appeal. Lift a boat's hull clear of the water, reduce drag and move passengers faster while consuming less energy. I've written before about the proposed electric hydrofoil ferry between Vancouver, Bowen Island and Gibsons, where floating logs, coastal conditions and uncertain passenger demand make the economics ...
