About the curve:

• The Keeling Curve is a graph of the accumulation of carbon dioxide in the Earth's atmosphere.
• It is based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
• The curve is named for the scientist Charles David Keeling, who started the monitoring program and supervised it until his death in 2005.
• Keeling's measurements showed the first significant evidence of rapidly increasing carbon dioxide (CO2) levels in the atmosphere.
• Many scientists credit the Keeling curve with first bringing the world's attention to the current increase of CO2 in the atmosphere.
