The biological productivity of the Southern Ocean in the summertime is substantially greater than many previous estimates have suggested, according to new airborne research by the U.S. National ...

Rivers have long played a key role in the planet’s carbon cycle. They move and release gases like carbon dioxide (CO₂) and methane (CH₄), connecting land, air, and ocean systems. Until recently, ...

A new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as CO₂ released from the surfaces of ...

The carbon cycle is Earth's natural balancing act, moving carbon between the atmosphere, oceans, land, and living organisms. Human activities like burning fossil fuels are disrupting this flow, ...

A new study by planetary scientists at Harvard offers an explanation for one of Earth’s great climate puzzles: how the Sturtian glaciation, an ancient ice age when the planet was nearly entirely ...

The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study. The carbon stored globally by plants is shorter-lived and ...

To mitigate the worst impacts of climate change, it's crucial to pull carbon dioxide out of the atmosphere. It's a challenge startups are tackling with approaches like Direct Air Capture, which uses ...

Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from freezing or quickly evaporating. However, geological evidence has led scientists to conclude ...
