Assessing coral bleaching vulnerability in the Caribbean

Climate change has fueled coral reef bleaching throughout the tropics, with negative consequences for reef ecosystems and the people who depend on them. A new study finds that in the Caribbean, independent island nations such as Cuba and Jamaica are less vulnerable to coral bleaching than island territories like Saint Barthélemy.
