Global warming, a radical idea?
Broadcast Date: April 21, 1975

Broecker of Columbia University. He predicts the planet is actually going to warm up soon thanks to all the carbon dioxide in the atmosphere. Frum wonders: is this just an "academic interest" or is it really important? "Possibly, it could be terribly important," answers Broecker in this 1975 clip.
