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.
This short video produced by NOAA tells the story of how Charles David Keeling of Scripps Institution of Oceanography, UC San Diego, worked with scientists from the U.S. Weather Bureau and NOAA at NOAA’s Mauna Loa Observatory to create what is now an iconic record of carbon dioxide in our atmosphere. The measurements of carbon dioxide in the atmosphere taken from 1958 to the present have become the most widely recognized record of mankind’s impact on the Earth, linking rising levels of carbon dioxide from man’s burning of fossil fuels to the warming of the planet.
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.
