Mountains preserve evidence of ancient oceans, moving continents and tectonic processes that have shaped Earth over millions of years. Later deformation, erosion and burial, however, can obscure important parts of this geological record. An international research team led by Istanbul Technical University (ITU) has…
Per- and polyfluoroalkyl substances (PFAS)—a vast family of chemicals used largely for their nonstick, water-repellent and grease-resistant properties—are called "forever chemicals" because of their remarkable resistance to degradation. They are now ubiquitous in our environment.
Polar oceans may play an important role in storing carbon and supporting biodiversity, but current science and policy frameworks are not yet ready to fully recognize their potential.
Filmmaker and outdoorsperson Quinn Barabash recently made headlines when he found a swordfish carcass nearly two meters (6.6 feet) long on the remote shores of Haida Gwaii in northern British Columbia.
Parts of Earth's climate system can change abruptly once warming pushes them beyond critical thresholds. The Greenland and Antarctic ice sheets, the Amazon rainforest, coral reefs and major ocean currents are all among the systems containing potential climate tipping points.
Nitrogen is one of life's building blocks, but it's only helpful in the right amounts. Too much nitrogen in water, for example, can lead to poor water quality and the gradual death of aquatic organisms. Microbes remove nitrogen from water by converting it to a gas that escapes into the atmosphere. But scientists have…
Climate change is worsening. There's now no chance of holding temperature rise to 1.5°C. The future will bring worsening floods, glacial melt, megafires and lethal heat.
Image: While the final eight IRIDE Eaglet II satellites were launched a week ago, the first images from Eaglet II satellites launched earlier are being returned, including a view of Gibraltar featured here.
Malaysia closed schools in Kuala Lumpur and other parts of the country Friday as haze from fires in neighboring Indonesia again pushed local air quality to some of the world's worst levels.
Isaias strengthened to a Category 2 hurricane on Thursday as it headed toward the U.S. Gulf Coast, the U.S. National Hurricane Center said, prompting mandatory evacuations and disrupting oil and gas production.
