The Scripps CO2 measurements at Mauna Loa have been supported for many years by the U.S. Department of Energy (DOE), and have more recently been supplemented by Earth Networks, a technology company that is collaborating with Scripps to expand the global GHG monitoring network. Support for website development was provided in part by the National Science Foundation (NSF).

Supports continued operation of the iconic measurement series Scripps Institution of Oceanography at UC San Diego today announced that Wendy and Eric Schmidt have provided a grant that will support continued operation of the renowned Keeling Curve measurement of atmospheric carbon dioxide levels. The grant provides $500,000 over five years to support the operations of the Scripps CO2 Group, […]
The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve.
In response to a recent reader comment about wide fluctuations in CO2 readings at Mauna Loa, Ralph Keeling and Stephen Walker of the Scripps CO2 Group gave the following answer: It’s fairly normal, especially in the summer time, to see strong afternoon “dips” in the CO2 concentration. The dips are generally caused by upslope winds […]
Several readers have asked why Keeling Curve cannot set up a mechanism to receive donations via PayPal. The short answer is that to do so would violate University of California policy. The UC Office of the President has found that PayPal’s security procedures do not comply with UC standards. For the latest on support efforts for […]
The Mauna Loa carbon dioxide (CO2) record, also known as the “Keeling Curve,” is the world’s longest unbroken record of atmospheric carbon dioxide concentrations. This record, from the NOAA-operated Mauna Loa Observatory, near the top of Mauna Loa on the big island of Hawaii, shows that carbon dioxide has been increasing steadily from values around […]
