Great Barrier Reef suffers 89% collapse in new coral after bleaching events

Study shows dramatic fall in baby coral numbers but also change in type of coral

The number of new corals on the Great Barrier Reef crashed by 89% after the climate change-induced mass bleaching of 2016 and 2017.

Scientists have measured how many adult corals survived along the length of the world's largest reef system and how many new corals they produced in 2018 in the aftermath of severe heat stress and coral mortality.
