Son of climate pioneer Keeling takes over role

In 1958, Charles Keeling began monitoring CO2 levels – a measurement now known as the Keeling Curve.

We would not have any direct evidence of carbon dioxide in the atmosphere if it was not for Charles Keeling.

Back in 1958, he began monitoring CO2 levels – a measurement now known as the Keeling Curve.

He painstakingly recorded CO2 levels every day for decades. And that is a job his son Ralph has now taken over.
