Kuwaiti oil fires

During Operation Desert Storm, Dr. S. Fred Singer debated Carl Sagan on the impact of the Kuwaiti oil fires on ABC News[?] "Nightline." Sagan said the smoke would loft into the upper atmosphere, disrupt the monsoons and lead to ecological disaster. Singer said such a view was ridiculous, that the smoke would go up only a few thousand feet and then rain out. Three days later, black rain began falling over Iran, which pretty much put an end to the speculation.
