A bit of good news about the health of Earth’s highly sensitive coral reefs: Some are more resilient than others, at least in Australia’s Great Barrier Reef.

After a 2016 marine heat wave destroyed or severely damaged corals in the Great Barrier Reef, a period of extreme warmth a year later revealed to scientists that the survivor corals adapted to the higher temperatures. Their findings were published in the journal Nature Climate Change, detailing how extreme climate change affects such ecosystems.
