Global Warming Disrupts Recovery of Coral Reefs The damage caused to the great barrier reef by global warming has compromise the capacity of corals to recover, according to new research published today in nature. Professor Terry Hughes, director of the arc centre of excellence for coral reef studies at James Cook University (JCU), said dead corals don't make babies. The number of new corals settling on the great barrier reef has declined by 89 percent following the unprecedented loss of adult corals from global warming in 2016 and 2017. The unique study measured how many adult corals survived along the length of the worlds largest reef system following extreme heat stress, and how many new corals they produced to replenish the great barrier reef in 2018. The loss of adults resulted in a crash in coral replenishment compared to levels measured in previous years before mass coral bleaching. Co-author, professor Andrew Bird, said the number of coral larvae that are produced each year, and where they travel to before settling on a reef, are vital components of the resilience of the great barrier reef. Our study shows that reef resilience is now severely compromise by global warming. So far, the great barrier reef has experienced four mass bleaching events due to global warming, in 1998, 2002, and back-to-back in 2016 and 2017. Scientists predict that the gap between pairs of coral bleaching events will continue to shrink as global warming intensifies. Hughes said there only one way to fix this problem and thats to tackle the root cause of global heating by reducing net greenhouse was emissions to zero as quickly as possible. Answer the question. 3. What did professor Hughes say about dead corals?
