George Shea published a video of his play (1 hour, 17 mins), Dr. Keeling’s Curve, on YouTube in February 2017. Based at the Scripps Institute of Oceanography, Dr. Keeling measured carbon dioxide levels around the earth, starting in 1958. In plotting the graph of his findings over more than twenty years, he demonstrated it’s inexorable rise, the curve of which matched the rise in earth’s average temperature during the same time. It’s a powerful story, which isn’t hurt by the fact that Mike Farrell (M.A.S.H. fame) plays Dr. Keeling in this one-man play. How is it that we don’t all know about this?
Keeling’s curve, and the history of carbon dioxide in the earth’s climate are expanded in videos from the American Museum of Natural History.
