Earth-Shattering: Violent Supernovas, Galactic Explosions, Biological Mayhem, Nuclear Meltdowns, and Other Hazards to Life in Our Univer by Bob Berman
4.0
Somewhere in the 3.5 to 4 range. Berman does a good job of discussing some of the many ways - past, present, or future - that the earth and the universe are in danger (or have been impacted) by cataclysmic events. I did feel that he spent too much time on some of the items while barely covering some of the other ones, but overall it was well-written and informative.
