A study of fossils from the Permian-Triassic extinction event 252 million years ago shows that forests in many parts of the ...

Here's how much the balance has changed: For the last 400,000 years, the amount of carbon dioxide in the atmosphere fluctuated between 200 and 280 parts per million, according to NASA.

Within a human lifetime, concentrations of CO2 in Earth's atmosphere could reach levels associated with 19 "mass extinctions" that have taken place in the last 534 million years, new research ...

Roughly 252 million years ago, Earth experienced its deadliest known extinction. Known as the Permian–Triassic Mass ...

Although no one was around to measure the atmosphere's CO 2 concentration millions of years ago, paleoclimatologists can reconstruct past temperature and carbon dioxide levels using ice cores ...

A misleading graphic circulating on social media understates man-made contributions to carbon dioxide (CO2) levels in the Earth’s atmosphere, overstates “natural” levels and downplays the ...

Discussion of the greenhouse effect and the importance of maintaining a balance of carbon dioxide in the atmosphere. The main gases in the atmosphere that contribute to the greenhouse effect are ...

The CO2 – the compound humans breathe out – was found in the atmosphere of a planet orbiting a star 700 light-years away. It was discovered by the James Webb Space Telescope.

Webb Telescope Sees a Carbon Dioxide Atmosphere Way Out There. WASP-39b, ... The planet, known as WASP-39b, is a puffy and very hot gas giant, about the mass of Saturn.

For the first time, astronomers have found unambiguous evidence of carbon dioxide in the atmosphere of an exoplanet (a planet outside our solar system). The discovery, accepted for publication in ...

Chemically, carbon dioxide is incredibly simple—it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's ...
