For those that argue that the “science is still out” on global warming, it’s good to be reminded that we’ve already had more than a half-century.

Here’s an excerpt from the 1958 Frank-Capra-produced Bell Laboratory Science Series, from the episode The Unchained Goddess, in which Frank C. Baxter explains mankind’s long-term impact on the weather:

The Bell Laboratory Science Series is available on DVD as 2 episodes per disc.

The Bell Laboratory Science Series was a series of educational television specials made for Bell Labs by Frank Capra, Walt Disney, and others. Each special explored a single subject in detail. The host of seven of the eight films was Dr. Research, played by Frank C. Baxter. In one of the films, The Alphabet Conspiracy, Baxter played essentially the same character, but with his name changed to Dr. Linguistics. The host for the last film in the series was Walt Disney.

Each movie intertwined animation and live action to better explain the complexity of a particular subject.
