The Mauna Loa laboratory in Hawaii has measured atmospheric carbon dioxide, which — along with other planet-warming pollution ...

New data shows that CO2 levels have broken through 430 parts per million, an indication that human-caused global warming will ...

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 ...

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 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 ...

Scripps Oceanography has managed and monitored the Mauna Loa readings and charted the Keeling Curve since the late 1950s. Since 1974, NOAA also maintained records in cooperation with Scripps.

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.

Volcano eruption in Hawaii shuts down UCSD’s ‘Keeling Curve’ carbon dioxide tracker Researchers at UC San Diego’s Scripps Institution of Oceanography are scrambling to find a temporary ...

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 ...
