Using sophisticated equipment, David Kohlstedt has recreated the pressure, temperature and chemical conditions in the Earth’s mantle, which humans cannot observe directly. His findings have laid the basis for understanding many of the processes that drive the planet’s dynamics.

With the award of a 2022 Earthshot prize, new technology to remove carbon from the air by speeding up natural underground chemical reactions moves closer to reality.

A guide to some of the most provocative and groundbreaking talks at the world’s largest gathering of earth and space scientists.

Tharp co-published the first world map of the ocean floors and helped prove the theory of continental drift.

Several weeks during summer 2021 saw heat records in the western United States and Canada broken not just by increments, but by tens of degrees, an event of unprecedented extremity. To what degree was it climate change, bad luck, or a combination?

Dust from the land that gets blown into the ocean appears to influence natural climate swings. A new study looks into where much of that dust came from in the past 260,000 years.

As the Arctic melts, permafrost there has the potential to send huge amounts of carbon into the atmosphere, but exactly how much is up for grabs, depending on what we do to stem climate change in coming years.

Sudden plunges of lake waters from glacial surfaces to ice-sheet beds may not speed up the movement of Greenland’s tidewater glaciers, as previously thought.

Visitors played with glacial goo, watched trash cans erupt with water and ping pong balls, and performed hands-on science experiments — all while learning how Lamont researchers help us understand our planet.

Researchers are working at a remote ranch in the Aleutians, commuting by helicopter to the brim of a volcano to perform maintenance on their monitoring equipment.
