Great Barrier Reef ocean temperatures hit 400-year record: study

CANBERRA: For the past decade, water temperatures along Australia's famed Great Barrier Reef have been the warmest in 400 years, a major study said on Thursday (Aug 8).

Ocean temperatures around the spectacular coral system have increased yearly since 1960 but were particularly hotter during recent mass coral bleaching events, according to a study in the science journal Nature.
