Wonderful video of Dr. Isaac Asimov speaking at the Humanist Institute in January 1989.
The good doctor speaks of the threat of the greenhouse effect before it was fashionable. Part 1 identifies the problem. On Part 2 he offers answers.
From YouTube:
Part 1: Threats to Humanity
Part 2: The Answer for Humanity
