Noted actor and activist Mike Farrell plays Dr. David Keeling, the scientist whose research on CO2 gave the world its first early warnings of global warming. In this highly acclaimed performance, Farrell brings to life the quirky and brilliant man who created the Keeling Curve, the iconic chart that illustrates the rise in atmospherice CO2 levels from 1958 to the present.

The story combines Keeling's personal journey with the insights of atmospheric scientists who, hundreds of years earlier, made discoveries that laid the foundations for Keeling's own extraordinary work. We meet Jean Joseph Baptiste Fourier whose obsession with heat led to an understanding of the greenhouse effect, and Svante Arrhenius who proved a link between global warming and CO2. The play paints very human portraits of these and other great scientists.
