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.

By 2100, atmospheric carbon dioxide levels could rise to 800 parts per million by volume (ppmv) — almost double the concentration of roughly 421 ppmv recorded this year — if we fail to curb ...

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 ...

New research from the University of California, Davis, the Chinese Academy of Sciences and Texas A&M University reveals that massive emissions, or burps, of carbon dioxide from natural Earth systems ...

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 ...

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 ...

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.

The claim: The 'six great ice ages' began when CO2 was higher than now; all plants and animals die when CO2 levels are cut in half A July 4 post (direct link, archive link) on X, formerly Twitter ...

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.

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 ...
