The Blue Climate and Oceans Project - HOME. Keeling Curve. The Keeling Curve is a graph which plots the ongoing change in concentration of carbon dioxide in Earth's atmosphere since 1958. It is based on continuous measurements taken at the Mauna Loa Observatory in Hawaii that began under the supervision of Charles David Keeling. Keeling's measurements showed the first significant evidence of rapidly increasing carbon dioxide levels in the atmosphere.
Many scientists credit Keeling's graph with first bringing the world's attention to the current increase of carbon dioxide in the atmosphere.[1] Charles David Keeling, of the Scripps Institution of Oceanography at UC San Diego, was the first person to make frequent regular measurements of the atmospheric carbon dioxide (CO2) concentration, taking readings at the South Pole and in Hawaii from 1958 onwards.[2] Prior to Keeling, the concentration of carbon dioxide in the atmosphere was thought to be affected by constant variability.

The Keeling Curve: Atmospheric CO2 concentrations as measured at Mauna Loa Observatory Since 1956 Mauna Loa Observatory (MLO) has been monitoring and collecting data relating to atmospheric change, and is known especially for the continuous monitoring of atmospheric carbon dioxide (CO2), which is sometimes referred to as the Keeling Curve.
The latest observation of CO2 concentrations from MLO can be found at web sites along with data from other sites[2] and trends at Mauna Loa.[3] The MLO levels can be compared with other sites in the global monitoring network. MLO has activities at five locations on the Big Island.
