The keeling curve shows, the ongoing change in the concentration of carbon dioxide in the Earth's atmosphere since 1958.
Based on continuous observations made at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present, the Keeling Curve is a graph depicting the buildup of carbon dioxide in the Earth's atmosphere. The scientist Charles David Keeling, who initiated the monitoring program and oversaw it until his passing in 2005, is honored by the curve's name. The first convincing evidence of rapidly rising carbon dioxide (CO2) levels in the atmosphere was provided by Keeling curve's measurements. One of the most significant scientific discoveries of the 20th century, in the opinion of Harvard University's Naomi Oreskes, is the Keeling curve. Many scientists believe that the Keeling curve was responsible for drawing attention to the present increase in atmospheric CO2.
