A regional exchange of relatively small nuclear weapons could plunge the world into a decade-long "nuclear winter", destroying agriculture and killing millions, according to a new study. Now scientists have re-calculated the likelihood of nuclear winter using modern, vastly improved climate models and a more likely modern scenario for small-scale nuclear war. Brian Toon, head of atmospheric and oceanic sciences at the University of Colorado at Boulder, and Alan Robock of Rutgers University in New Jersey, both in the US, predict less cooling than the 1980s modellers. However, they predict the cooling would last longer, with potentially devastating consequences. For the full article Click Here .

Good link. Very interesting.

Very thought provoking, thanks. For all of our "wisdom", we still don't realize how fragile the biosphere is.
