The world's southernmost coral reef is on a "knife-edge" after warmer seas blamed on climate change bleached large parts of it for the first time, an Australian scientist warned on Wednesday. Peter Harrison, who has been monitoring the world heritage-listed Lord Howe Island since 1993, said a two degrees Celsius (four Fahrenheit) rise in sea temperatures had drained much of the reef of its distinctive colours. "We're hoping the vast majority of these corals will be able to recover, but at the moment this whole system is on a knife-edge and we don't know what's going to happen," Harrison told AFP.
