On Earth, our familiar carbonate is calcite (calcium carbonate), forming vast limestone deposits. This is a cornerstone of Earth's long-term carbon cycle: volcanic CO2 enters the atmosphere, dissolves ...

Ancient carbon is trapped in rocks, peat bogs and wetlands. The findings suggest that as much as 1 gigatonne of it is being released back into the atmosphere each year through rivers.

NASA's Curiosity rover has uncovered evidence of a past carbon cycle on Mars. This breakthrough provides scientists with new insights into the Red Planet's potential to have hosted life. This ...

Carbon sequestration Rover finds hints of an ancient Martian carbon cycle Rather than cycling, some of Mars' carbon took a one-way trip into rocks.

Global heating over this millennium could exceed previous estimates due to carbon cycle feedback loops. This is the conclusion of a new study by the Potsdam Institute for Climate Impact Research ...

Reaching net-zero carbon emissions goals requires finding transformative paths to manage carbon in difficult-to-electrify economic sectors.

Plastic has become a major part of the carbon cycle, a discovery that has implications for how we tackle climate change.

Through its effects on the plants, animals and microbes which make up the biosphere, on the climate and on the oceans, this industrial flow of carbon links the Earth’s distant geological past to ...

Most of Earth’s carbon is stored inside the planet. But giant lava outflows and now humans have released huge amounts of carbon into the atmosphere.

Since 1750, humans have disrupted Earth's carbon cycle more severely than have some of the most cataclysmic asteroid impacts in history — and, new research suggests, the long-term effects on our ...

The 2nd State of the Carbon Cycle Report (SOCCR-2) reports on changes to sources and sinks of atmospheric carbon in North America. Although addressed to policy makers and citizens alike, the report ...
