The Keeling Curve is the record of atmospheric CO₂ from the Mauna Loa Observatory, starting in 1958.

Scripps CO₂ measurements at Mauna Loa are currently supported by Schmidt Sciences with supplemental support from Earth Networks, a technology company collaborating with Scripps to expand the global GHG monitoring network. Support for website development was provided in part by the National Science Foundation (NSF). The Mauna Loa Observatory is run by the National Oceanographic and Atmospheric Administration.
