Water Too Hot? Hope for a Hurricane
Posted on July 5th, 2007 by Scientific American - Nature
A hurricane can destroy a coral reef. The fragile superstructure created by millions of marine microorganisms does not fare well when slammed by high winds and powerful waves. But coral reefs worldwide have bigger fish to fry, so to speak, most notably the bleaching brought on by warmer waters. In that case, it appears that hurricanes are actually a boon.
