As warmer waters and ocean acidification reduce coral formation, the seas will take up more carbon dioxide – an effect that ...

In 1850, the atmospheric CO2 concentration was about 280 parts per million. The increase to the current level of 421 parts per million is all a result of human activity, Schmidt told USA TODAY in ...

The latest anomaly in the climate system that can’t be fully explained by researchers is a record annual jump in the global mean concentration of carbon dioxide in the atmosphere measured in 2024.

Over the last decade, humanity's emissions of carbon dioxide (CO₂) have stabilized after a period of huge growth. Average growth is now down to just 0.6% per year, compared to 2% per year in the ...

The concentration of CO2 in Earth’s atmosphere has increased, opens new tab from around 278 parts per million (ppm) (0.028%) in 1750 to 417 ppm (0.042%) in 2022, according to Copernicus data.

The concentration of carbon dioxide in the atmosphere is measured in parts per million, and measurements are taken at an observatory in Hawaii. In May, the atmospheric CO2 concentration peaks ...

Carbon dioxide may be a naturally occurring substance on Earth, but too much of its presence has contributed to global ...

The work has revealed a contradiction: while atmospheric CO2 is the main source of carbon for crops, its high concentration in the atmosphere limits the presence of phosphorus fertilizer in the ...
