Climate change has killed billions of corals and fundamentally changed coral reefs. The response, especially in Australia, has been to fix the symptoms, not address the cause – climate change for which humans are responsible.
Much money and research effort is expended in replacing, regrowing and supporting corals, in the hope reefs may survive a warmer world.
These technological and scientific “solutions” give hope that something can be done. But as we argue in Nature Climate Change today, there is little evidence these measures will create resilient or healthy reef ecosystems over the long term.
