Caribbean corals struggling to produce enough calcium carbonate to survice
By Summit Voice
SUMMIT COUNTY — Many coral reefs in the Caribbean are struggling to keep pace with erosion, as their ability to produce and accumulate calcium carbonate declines in the face of human-caused impacts, researchers from the University of Exeter reported this week. That inability to grow raises serious questions about whether the reefs will be able to adapt to rising sea levels, the researchers reported.
Coral reefs are important ocean biodiversity hotspots and serve as nurseries for a profusion of marine life. In a sweeping decision several weeks ago, federal biologists said at least 66 species of coral in the Caribbean and Pacific are in danger of going extinct because of threats linked to global warming caused by greenhouse gas emissions.
Coral cover on reefs in the Caribbean has declined by an average of 80 percent since the 1970s, driven mainly by human disturbance, disease and rising sea temperatures, and are only expected to intensify as a result of future climate change. (more…)
