Global Warming Predictions 50 Years Ago

There is only one little problem with this entertaining film: temperatures had started falling in the late 1930s and continued falling until the late 1970s. This film at least has the amusing title of "The Unchained Goddess." Possibly the problem isn't that they aren't right at the margin, but that the impact from man is so small that it doesn't really alter these overall patterns very much. I am pretty sure that I have seen this before, possibly as a kid in the late 1960s.
