maybe you should stop attacking carl sagan? or show some actual evidence for your attacks.

SINCE 1983, scientists have been bitterly divided over whether a nuclear war is likely to result in a catastrophic global chilling. But the five scientists who introduced the term ''nuclear winter'' now acknowledge that they overestimated its severity, and their concession appears to have moderated the longstanding debate.

Maybe you should try to know a little about what you are talking about.

please reread my first comment, it explains why you are wrong and sagan was right. also, try googling climate models (they are not just for global warming) and the super computers that do the heavy lifting. i sure hope you educate yourself.

Sagan himself said the paper was incorrect.

Though I am certain you know better.
