Keeling Curve, Carbon Dioxide Measurements

The Keeling Curve is a record of atmospheric carbon dioxide measurements taken from the Mauna Loa Observatory in Hawaii. In 1958, Charles D. Keeling began measuring atmospheric CO2 levels, which have rapidly increased over the years most likely due to the burring of fossil fuels such as coal, oil and natural gas. Atmospheric CO2 has recently reached 400 parts per million (ppm), raising concerns about the long term environmental effects from our global dependence on fossil fuels. Before the Industrial Revolution, atmospheric CO2 varied from 200-300ppm as natural climates shifted between ice ages and warmer periods. Geochemical records have shown that atmospheric CO2 had reached 400ppm during the Pliocene Ephoch, three to five million years ago and before human inhabitance.
