I would recommend this book to anyone who is concerned about these issues. Although I can't agree with everything in it, I know that those who read it are likely to be skeptical and discerning enough to make up their own minds. And the book is certainly quite readable. Most of the anecdotes and trends he cites are easily verified by a casual observer. You can say that about Nostradamus.
Nuclear winter is a good example.
Sagan once said that some issues were too important for mere truth. And it shows an attitude I cannot encourage people to accept. I concede the point. Pseudoscience is, in my opinion, a serious problem requiring serious thought. But most of the people who are against it do little more than whine about it.
