The number of new corals on the Great Barrier Reef crashed by 89% after the climate change-induced mass bleaching of 2016 and 2017. The results, published in Nature, show not only a dramatic reduction in new coral recruitment compared with historic levels, but also a change in the types of coral species produced. Across the entire reef the scientists measured an 89% drop in new corals, but that average includes a small increase in new coral in the southern-most sections of the reef, which were less affected by bleaching.
