What endangers one of world's most vibrant Hawaii's coral reefs

Just four years after a major marine heat wave killed nearly half of Hawaii's coral reefs, researchers are predicting another round of hot water will cause some of the worst coral bleaching the region has ever seen. Here's what is endangering the world's most abundant and vibrant coral reefs:

At the edge of an ancient lava flow where jagged black rocks meet the Pacific, small off-the-grid homes overlook the calm blue waters of Papa Bay on Hawaii's Big Island — no tourists or hotels in sight. Here, one of the islands' most abundant and vibrant coral reefs thrives just below the surface.

Yet even this remote shoreline far from the impacts of chemical sunscreen, trampling feet and industrial wastewater is showing early signs of what's expected to be a catastrophic season for coral in Hawaii.

Just four years after a major marine heatwave killed nearly half of this coastline's coral, federal researchers are predicting another round of hot water will cause some of the worst coral bleaching the region has ever seen.

"In 2015, we hit temperatures that we've never recorded ever in Hawaii," said Jamison Gove, an oceanographer with the National Oceanic and Atmospheric Administration. "What is really important — or alarming, probably more appropriately — about this event is that we've been tracking above where we were at this time in 2015."
