*Though Dr. Sagan is one of the most frequently cited experts on atmospheric issues by the media, his predictions are often wrong. For example, at the outset of the Persian Gulf War, Sagan warned that if Saddam Hussein delivered on his threat to set fire to Kuwait's oil wells, so much black soot would be sent into the stratosphere that sunlight would be blocked and a variation of the "nuclear winter" scenario would occur. Hussein followed through on his threat and by the close of the war over 600 wells were on fire. But the fires had little environmental or climatic effect beyond the Gulf region and virtually no ill effects globally. [http://www.nationalcenter.org/dos7124.htm]

[[Fred Singer]] famously rebutted Sagan's prediction on national TV and was vindicated a few days later, when Sagan's "[[nuclear winter]] scenario failed to materialize. <ref>"Retired atmospheric physicist Fred Singer dismissed Sagan's prediction as nonsense, predicting ['''correctly'''] that the smoke would dissipate in a matter of days."
