Detailed explanation-1: -The Keeling Curve is a graph of the accumulation of carbon dioxide in the Earth’s atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.

Detailed explanation-2: -CO2 in the Ice Core Record Today, however, for the first time in more than 400, 000 years, CO2 is at 390 parts per million and continuing to rise at 2 parts per million (ppm) per year.

Detailed explanation-3: -Charles David Keeling of Scripps Institution of Oceanography was the leading authority in establishing the global atmospheric carbon dioxide (CO2) record. In 1958, Keeling began measuring atmospheric CO2 concentrations from Hawaii’s Mauna Loa Observatory.

Detailed explanation-4: -The Keeling Curve is a measurement of the concentration of carbon dioxide in the atmosphere made atop Hawaii’s Mauna Loa since 1958. It is the longest-running such measurement in the world. The Scripps CO2 program was initiated in 1956 by Charles David Keeling and operated under his direction until his death in 2005.
