The BBC reported unheard of levels of coral bleaching in continuous years that has destroyed two thirds of Australia’s Great Barrier Reef. Bleaching is loss of algae and has affected a 1,500km (900 miles) of the reef, according to scientists.

Prof Terry Hughes and expert from James Cook University, said governments must address climate change to prevent bleaching. He said “Since 1998, we have seen four of these events and the gap between them has varied substantially, but this is the shortest gap we have seen”.
