Aerial survey data from the three mass bleaching events on the Great Barrier Reef

In 1979 widespread bleaching was seen for first time stretching throughout the Caribbean and the Florida Keys. 

According to the UN report on climate change that Australia had itself deleted from, and a paper in Nature it cites, a 2C rise in global surface temperatures will result in the loss of more than 95% of coral around the world.If the world limits warming to 1.5C, we might save 10%.

If we want to save 50% of what’s around right now, we need to limit warming to just 1.2C – and we’re already more than 80% of the way there.
