With all due respect to T. S. Eliot, maybe the world really does end with a bang, not a whimper. Whether of our own creation (nuclear holocaust) or of nature’s (asteroid impact), plenty of cataclysms could doom civilization—perhaps even putting the survival of the species in jeopardy.

The probabilities listed here are not scientific fact—an impossible goal when estimating the possibility of unprecedented events—but informed conjecture based on researchers’ expert opinions.
