The 2016 bleaching event resulted in 30% mortality on the Great Barrier Reef, with many corals dying of the heat before they bleached and the loss of branching corals creating less complex reef structure.
Corals near Lizard Island on the northern Great Barrier Reef experienced some of the worst bleaching in 2016.

The 2016 bleaching on the Great Barrier Reef was the worst on record. Now a new analysis points the finger squarely at human-induced warming, and warns that the entire reef's future is at stake.
The extent of future coral bleaching is likely to vary from place to place.

Regional variations in sea temperature can make all the difference between a coral reef suffering major bleaching or surviving as a refuge for corals, new research shows.

The Great Barrier Reef is in crisis, as a second wave of coral bleaching hits. But the system of bodies and laws that protect it are getting more complicated – and less productive.
The Great Barrier Reef is bleaching again, in its first back-to-back mass bleaching event.
The Great Barrier Reef is bleaching again. Without greater action on climate change and water quality, its World Heritage status could be listed as "in danger".

Two-thirds of the corals in the northern part of the Great Barrier Reef have died on in the reef's worst-ever bleaching event, according to the latest underwater surveys.
Bleached corals are still alive, but they are starving, and often die in the following weeks.
Months after record breaking coral bleaching, research teams are taking stock of the damage on the Great Barrier Reef.

Member of the Climate Council this week returned to one of the areas of the Great Barrier Reef that was worst affected by this year's coral bleaching. What they found was far from encouraging.

An estimated one-third of corals have now died in the parts of the Great Barrier Reef hit hardest by bleaching, meaning recovery could take years or even decades.
Perception is everything when it comes to Great Barrier Reef tourism.

The statistic that bleaching has been seen in 93% of surveyed areas of the Great Barrier Reef has sparked worldwide coverage - not all of it accurate.
