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

Carbon dioxide is a greenhouse gas that causes climate change. Here's what to know about carbon dioxide, carbon and global warming.

The research looked at peaks in biodiversity loss and their relationship with atmospheric CO2, finding 50 events over the last 534 million years that can be considered mass extinctions.

John Muir once said, “When we try to pick out anything by itself, we find it hitched to everything else in the ...

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 ...

Purported ice age data isn't nearly as clearcut as claimed, and plants and animals survive when CO2 levels are half of modern levels.

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.

New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will continue to warp the environment.

Webb Telescope Sees a Carbon Dioxide Atmosphere Way Out There WASP-39b, a distant world with a mass equivalent to Saturn’s, is the first exoplanet known to harbor the gas.

UCSC astronomer Natalie Batalha leads a team that detected carbon dioxide in the atmosphere of the exoplanet WASP-39b using the James Webb Space Telescope.

This graphic indicates Earth’s atmospheric concentrations of CO2, expressed in parts per million (ppm), throughout the Cenozoic era from pre-industrial times back 65 million years. These are ...

Carbon dioxide is what people and animals breathe out after breathing in oxygen. But that's balanced by the plants we eat, so humans and animals aren't affecting the balance of atmospheric CO 2.
