Viral posts claimed scientists developed "artificial trees" to clean the air 1,000 times more efficiently than real trees.

Earth inhales and exhales carbon, indicating where and when vegetation is growing (sucking up carbon dioxide) or dying off (releasing carbon dioxide).

Yet the new study reveals that many proposed marine carbon dioxide removal (mCDR) methods—especially those based on biological processes—could in fact intensify oxygen loss in the ocean.

The nascent carbon dioxide removal industry expects to hit a milestone this year: 1 million tonnes of planet-warming CO2 removed from the atmosphere. That certainly is progress, but things aren ...

Researchers develop a nickel catalyst that converts carbon dioxide to carbon monoxide with 99% selectivity by precisely tuning the electronic structure of the nickel atoms.

The James Webb Space Telescope has directly observed the key chemical of carbon dioxide in planets outside of our solar system for the first time, scientists announced Monday. The gas giants are ...

This artificial leaf makes hydrocarbons out of carbon dioxide The solar-powered device can make valuable energy-dense molecules from carbon dioxide and water.

This New, Yellow Powder Quickly Pulls Carbon Dioxide From the Air, and Researchers Say ‘There’s Nothing Like It’ Scientists say just 200 grams of the material could capture 44 pounds of the ...

But what happens if it leaks? California’s carbon deadline is approaching, but activists worry that piping millions of tons of carbon dioxide to the Central Valley could lead to disaster.

A high-resolution visualization from NASA's Scientific Visualization Studio shows global carbon dioxide emissions from January to March 2020.

The amount of planet-warming carbon dioxide in the Earth’s atmosphere has hit a new record, as humanity struggles to rein in emissions of greenhouse gasses from burning fossil fuels.

Carbon dioxide "acts like a blanket in the atmosphere," NOAA explained — much like other greenhouse gases that amplify the sun's heat toward Earth's surface.
