This video is part of a longer presentation at the Humanist Institute in New York in 1989, and it demonstrates yet again that the broad outlines of the climate change story have been understood for decades by, well, intelligent men who are guided by science.
During the late 1950s and 1960s, Asimov shifted gears somewhat from science fiction to sc ience, and substantially decreased his fiction output (he published only four adult novels between 1957's The Naked Sun and 1982's Foundation's Edge, two of which were mysteries). At the same time, he greatly increased his non-fiction production, writing mostly on science topics; the launch of Sputnik in 1957 engendered public concern over a "science gap", which Asimov's publishers were eager to fill with as much material as he could write.
Meanwhile, the monthly Magazine of Fantasy and Science Fiction invited him to continue his regular non-fiction column, begun in the now-folded bimonthly companion magazine Venture Science Fiction Magazine, ostensibly dedicated to popular science, but with Asimov having complete editorial freedom. The first of the F&SF columns appeared in November 1958, and they followed uninterrupted thereafter, with 399 entries, until Asimov's terminal illness.
These columns, periodically collected into books by his principal publisher, Doubleday, helped make Asimov's reputation as a "Great Explainer" of science, and were referred to by him as his only pop-science writing in which he never had to assume complete ignorance of the subjects at hand on the part of his readers. The popularity of his first wide-ranging reference work, The Intelligent Man's Guide to Science, also allowed him to give up most of his academic responsibilities and become essentially a full-time freelance writer.
