A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.

How to set carbon prices that are consistent with goals of both climate experts and economists.

A new approach to carbon pricing avoids the pitfalls of calculating the social costs of carbon.

Starting this month, scientists aim to study the Antarctic Circumpolar Current’s past dynamics by drilling into the seabed in some of the planet’s remotest marine regions.

A new website provides an interesting and easy-to-understand primer on the carbon cycle.

Coastal waters play an important role in the carbon cycle by absorbing carbon into sediments or transferring it to the open ocean, a new study confirms.

Mercury’s dark surface is revealing intriguing new clues about the formation of the solar system, including evidence announced today that the planet closest to the Sun may have formed in part from carbon, a key component of life.

Globally, individual nations have volunteered greenhouse gas reduction targets in anticipation of the Paris meetings. Unlike Copenhagen, where calls for mandatory reductions and transfer payments to the developing world caused the collapse of any potential agreements, the world community seems more realistic as it approaches the Paris meetings.

The Indonesian peat fires that have been choking cities across Southeast Asia with a yellow haze are creating more than a local menace—burning peat releases immense stores of CO2, contributing to global warming.
