Hans Kristensen and co-authors explore the consequences of a hypothetical nuclear exchange. “…There could be famine for millions or billions of people – even for the smaller amounts of smoke in the scenarios presented here.”
A report by Alan Robock, Owen B. Toon, Charles G. Bardeen, Lili Xia, Hans M. Kristensen, Matthew McKinzie, R. J. Peterson,Cheryl S. Harrison, Nicole S. Lovenduski and Richard P. Turco.
This article describes how an India-Pakistan nuclear war might come to pass, and what the local and global effects of such a war might be. The direct effects of this nuclear exchange would be horrible; the authors estimate that 50 to 125 million people would die, depending on whether the weapons used had yields of 15, 50, or 100 kilotons. The ramifications for Indian and Pakistani society would be major and long-lasting, with many major cities largely destroyed and uninhabitable, millions of injured people needing care, and power, transportation, and financial infrastructure in ruins. But the climatic effects of the smoke produced by an India-Pakistan nuclear war would not be confined to the subcontinent, or even to Asia. Those effects would be enormous and global in scope.
