Climate change presaged

I’ve known about climate change and greenhouse gases since 1988.

We can’t say we weren’t warned!

1980: Walter Cronkite on Climate Change

The warnings go back even further than that

1958 - Global Warming - It's NOT newly known

For FIFTY YEARS scientists have known about global warming. This exerpt is from the well known educational documentary "Unchained Goddess" produced by Frank Capra for Bell Labs for their television program "The Bell Telephone Hour." It was so well made, that it went on to live a continued life in middle school science classrooms across the nation for decades.
