Carbon Dioxide

Cooling caused by volcanic eruptions accounts for 15 percent of the global warming "pause," the mismatch between actual warming and climate-model predictions.

Rapidly growing mountains have higher rates of soil production and weathering than scientists thought possible, suggesting they may be able to act as carbon sinks.

Jumping sea snails may turn sluggish due to ocean acidification, as lower pH levels disrupt their ability to flee predators, a new study finds.

A type of greenhouse gas that is thought to have a potent impact on global warming was detected in trace amounts in the atmosphere for the first time, according to a new study.

The higher levels of carbon dioxide in the atmosphere could spur mold to grow more allergenic proteins, exacerbating people's response to the fungus, new research finds.

In one of the most shocking tales of survival-at-sea ever told, a man lived for almost three days inside a sunken ship at the bottom of the ocean.

By aerating cow dung, dung beetles may help reduce the amount of methane released into the atmosphere, a new study suggests.

A report assessed the capacity of the U.S. to store carbon dioxide inside rocks deep underground.
