The Nuclear Winter Meltdown, (see below) has given rise to a warm exchange with Eric Hundman of the Center for Defense Information : http://www.defensetech.org/archives/003108.html
When I have finished reading the second of the new studies by Robock et al. dealing with the injection of 5 teragrams or so of soot into model atmospheres I may draft a formal response to submit to the peer reviewed literature in which they appeared. Right now, I'm waiting for the Harvard library system to awake from its customary two-week Yuletide nap to review the refernces in the first.
It is no small irony that if one takes these papers , er, interesting, assumptions about the lifetime of and distribution of stratospheric aerosols to heart, one must take Paul Crutzen's proposal for using sulfate precursors to intervene in climate change very seriously indeed. On the other hand, in 1991, during Operation Desert Storm , Carl Sagan predicted a global climatic impact from multiteragram soot emissions from the Kuwaiti petroleum fires on ABC News Nightline. Sagan said smoke from the sooty holocaust would loft into the upper atmosphere and disrupt the monsoons , creating a disasterous Asian famine. Others objected that instead of being lofted by solar heating, the soot would be be washed out of the atmosphere by rainfall. Three days later, black rain began falling over Iran and a normal monsoon season followed. Instead of a global catastophe, as modeled in 1983, and by Robock et al.
