What I remember most of this book is that it scared the @#%$*&amp; out of me! This was one of the earliest popular works about nuclear winter. As a teenager in the midst of the Cold War, it firmly influenced my thinking on this subject. Not for the weak at heart -- this book is certainly not written in Sagan's usual style. It's definitely drier, if I remember correctly. But if you are interested in the subject, I recommend it. As far as I am aware, the findings of the early nuclear winter studies have not been refuted by subsequent science.

A Path Where No Man Thought: Nuclear Winter and Its Implications

Big nuclear wars cause fires that put so much soot into the air that it can kill crops for years.  But the cost in lives from the blasts alone is already so unthinkable that it's difficult for me to care about this added cost. Maybe this is due to my privilege from living in a time where nuclear war is synonymous with near human extinction, and I take it for granted that people understand this. Maybe Sagan helped this come about.  Still a boring read... from my favorite author of all time.
