Gore's Guru Disagreed

In the history of the global-warming movement, no scientist is more revered than Roger Revelle of Scripps Institution of Oceanography, Harvard University and University of California San Diego. He was the co-author of the seminal 1957 paper that demonstrated that fossil fuels had increased carbon-dioxide levels in the air. Under his leadership, the President's Science Advisory Committee Panel on Environmental Pollution in 1965 published the first authoritative U.S. government report in which carbon dioxide from fossil fuels was officially recognized as a potential global problem. He was the author of the influential 1982 Scientific American article that elevated global warming on to the public agenda. For being "the grandfather of the greenhouse effect," as he put it, he was awarded the National Medal of Science by the first President Bush.

Roger Revelle's most consequential act, however, may have come in his role as a teacher, during the 1960s at Harvard. Dr. Revelle inspired a young student named Al Gore.

Dr. Revelle would change Gore's life, particularly since the climate-change field had become cutting edge, with Dr. Revelle adding to the excitement by giving his students advance notice of the fruits of his research.
