Independent: Scientists have expressed alarm at the devastating impact of climate change on the world's coral reefs. More than a third of Earths reefs are now under threat due a process known as bleaching, in what could be the worst crisis ever to hit these vital ecosystems. Bleaching, where the symbiotic relationship between algae and small animals called polyps breaks down, can occur under heat stress and has been linked to multiple weather events including the latest severe El Nio phenomenon. The...

New York Times: Kim Cobb, a marine scientist at the Georgia Institute of Technology, expected the coral to be damaged when she plunged into the deep blue waters off Kiritimati Island, a remote atoll near the center of the Pacific Ocean. Still, she was stunned by what she saw as she descended some 30 feet to the rim of a coral outcropping. "The entire reef is covered with a red-brown fuzz," Dr. Cobb said when she returned to the surface after her recent dive. "It is otherworldly. It is algae that has grown over...

CBC: The coral on the sea floor around the Pacific island of Kiritimati looked like a boneyard in November stark, white and lifeless. But there was still some hope. This month, color returned with fuzzy reds and browns but that's not good news. Algae has overtaken the lifeless coral on what had been some of the most pristine coral reefs on the planet, said University of Victoria coral reef scientist Julia Baum after dozens of dives in the past week. Maybe 5 percent will survive, she estimated....

Washington Post: Scientists have declared that key portions of the Great Barrier Reef -- over a thousand miles long and the largest living structure on the planet, according to Australias Great Barrier Reef Marine Park Authority -- are now seeing the worst coral bleaching in recorded history. Were seeing very severe bleaching in the northern part of the reef, said professor Terry Hughes of James Cook University, where he heads the Australian Research Council (ARC) Centre of Excellence for Coral Reef Studies....
