HONOLULU — Scientists have found the first evidence of coral bleaching in the Hawaiian Islands, providing a worrisome sign of more potential environmental damage from global warming.
Coral bleaching happens when the algae that populate and build the coral die off.
The bleaching was discovered around the northwestern Hawaiian Islands, 10 mostly uninhabited islets and atolls that extend 1,200 miles northwest of the main Hawaiian Islands. The reefs are some of the most pristine in the world.
