The urgent need: today, the world captures only 200 tons of CO2 a year, while the required level stands at ten billion tons.

A new study finds that ocean acidity may have prevented life on Earth from developing for the planet’s first 500 million ...

Researchers have developed a reactor that pulls carbon dioxide directly from the air and converts it into sustainable fuel, using sunlight as the power source.

The results of Foote’s simple experiments were confirmed through hundreds of tests by scientists in the US and Europe. It ...

Peat bogs sequester a massive amount of the Earth's carbon dioxide. But even as scientists work to better understand bogs' ...

Rising temperatures make plants lose more water, weakening their ability to absorb carbon dioxide and survive heat stress.

It is called a greenhouse gas because —like the glass structure of a greenhouse — carbon dioxide molecules trap heat in the atmosphere. Carbon dioxide accounts for two-thirds of the global warming ...

A new study reveals that peatlands—a vital carbon store that many people have never heard of—are dangerously under-protected, ...

Adaptation can also involve changing how and where people live, prohibiting them from rebuilding in areas that repeatedly ...
