Jenny Ferron The Keeling Curve Since 1958 the Keeling Curve has been measuring the amout of CO2 in our Earth's atmopshere.Dr. Charles David Keeling was the first to study the CO2 amout by watching the annual fluctuation.Which are the swirls on the graph.Studying the CO2 levels lead to Dr. Keeling discovering that the earth's system behaves regulary.Scripps institution of oceanography Scripps Institution of Oceanography Over time the graph showed the decay of land, plants and the use of fossil fuels. In the Early 70s the Keeling curve played a vital part in the launch of a CO2 reseach program. With data from the polar ice cores, scientists have been able to find the CO2 levels from 4000,000 years ago.In the days before industrarial life , the CO2 level was in the upper 200s
