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.

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 ...

For the first time, the seasonal peak of carbon dioxide concentrations in the atmosphere exceeded 430 parts per million (ppm) ...

Carbon dioxide is very good at trapping heat ... emissions is like turning on the tap in a bathtub and the amount of water in the tub is the atmospheric concentration. Earth has natural ways of ...

Total amount of CO2 in atmosphere more important than percentage ... "Thus, it is the total amount of CO2 that matters, not so much its concentration. On Mars, for instance, the air is 95% CO2 ...

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 ...
