Following a global underwater heatwave, scientists have confirmed that for the third time in history coral bleaching is taking place in the world's oceans.
Since 2014, climate change has caused the oceans to rise in temperature which in turn has affected the coral by bleaching them of colour and causing them to die. By the end of 2015, 38% of the world's coral reefs will have been affected and 5% will have died forever.
Unfortunately things are set to get only worse in 2016. El Nino continues to increase global temperatures and an area of hot water on the North Pacific Ocean, known as "The Blob" will mean that more of our coral reeefs will bleach and die.
Professor Ove Hoegh-Guldberg, director of the Global Change Institute at the University of Queensland, Australia, predicts that with the continued rise of global temperatures the worlds coral reefs will be totally wiped out by the middle of this century.
