Case in point: Satellites calculated the annual rise in atmospheric carbon dioxide to be 2.9 ppm over the same period—a lower number than Mauna Loa recorded, but still the second largest jump on ...

Let's look at global patterns in atmospheric CO2 concentrations by examining the Keeling curve. The Keeling Curve shows seasonal and annual changes in atmospheric carbon dioxide (CO2) concentrations ...
