For 67 years, the observatory on Hawaii's Mauna Loa volcano has been taking these measurements daily  — tracking the invisible gas that is building up in our atmosphere and changing life on Earth.

The Keeling Curve, once the noble graph soon to be named after Charles David Keeling, has been the world’s definitive record of atmospheric CO2 since 1958.

Keeling maintained this record, known as the Keeling Curve, using a running hodgepodge of short-term grants until 2005, at which point geochemist Ralph Keeling, a professor at UC San Diego’s ...

The Keeling Curves are a set of figures nobody argues with, and everybody knows. “Our measurements have a connection for people because they’re more aware of them. In a way, they’re globally ...

Perversely, while the Keeling Curve has attained iconic global importance, this actually can hinder, rather than help the funding situation. Environmental programs tend to be organized by geographic ...

“The Keeling Curve is going to be eligible for Medicare next March,” Lueker said. (He and the curve share a birthday.) As he drove higher, houses became fewer and the temperature fell.

In 1958, when the Keeling Curve began, the concentration of CO2 in the Earth’s atmosphere was 313 parts per million. In 2024, that had risen to 424.61 ppm, and this year, monthly average CO2 ...
