In honor of the 60th anniversary of the Keeling Curve, Ralph Keeling of the Scripps CO2 Program shows how scientists make carbon dioxide measurements and gives a guided tour of the original instruments his father, Charles David Keeling, developed to start the famous record known as the Keeling Curve. In 2018, carbon dioxide levels are expected to exceed 410 parts per million (ppm) on a regular basis for the first time in human history. Sixty years earlier at the beginning of the records, CO2 levels were at 315 ppm.

The story of the Keeling Curve is beautifully animated in this new video. The American Museum of Natural History will host a Google+ Hangout Sept. 9, 2014 on the topic of the Keeling Curve.
So we’ve reached 400 ppm.… Now what happens? Continue reading Now What?
Carbon dioxide is a greenhouse gas produced by natural processes and everyday human activities, especially the burning of fossil fuels. The Keeling Curve is a measurement of the concentration of carbon dioxide in the atmosphere made atop Hawaii’s Mauna Loa since 1958. Continue reading The History of the Keeling Curve
