Nuclear winter, would it happen?

  1. Apr 5, 2013 #1
    Models suggest that the ash and fumes caused by cities set on fire by nuclear war would cause a nuclear winter.

    Are these models still valid, or do more refined models suggest that such a scenario would not occour, or that even a limited nuclear war would cause an extended nuclear winter?

    What is the update on the model of nuclear winter out of the 80s?
