AP: Caribbean Coral Suffers Record Death
A one-two punch of bleaching from record hot water followed by disease has killed ancient and delicate coral in the biggest loss of reefs scientists have ever seen in Caribbean waters.
Early conservative estimates from Puerto Rico and the U.S. Virgin Islands find that about one-third of the coral in official monitoring sites has recently died.
These are corals that took hundreds of years to grow, many of which died off in the past three to four months.
