Call it climate change or not- doesn't matter... facts are facts- billions & billions being spent to repair / replace entire towns, cities... islands.   Warmer waters from disrupted gyrations will lead to not only more severe destruction ABOVE ground but also long-lasting, perhaps irreparable damage below the surface.  
If you travel to the Rocky Mountains National Forest, you'll see entire mountainsides of pine trees that are dead from the pine beetle infestation.  Bugs' population size used to be kept in check from 'harsh winters' and snow pack.  
Hopefully, people won't make the coral habitats a political issue and instead recognize its healthy presence is part of both a healthy coastal habitat AND strong facet of Island tourism.  Its to everyone's benefit to pursue multi-faceted solutions- reducing soil runoff, stopping pollutant runoffs that otherwise foster algal growth (NPK), and expanding the status of sanctuary status to assure protection for the viable, healthy coral reefs.
