Great Barrier Reef, Australia CNN —As the early-morning sun rises over the Great Barrier Reef, its light pierces the turquoise waters of a shallow lagoon, bringing more than a dozen turtles to life. CNN witnessed bleaching on the Great Barrier Reef in mid-February, on five different reefs spanning the northern and southern parts of the 2,300-kilometer (1,400-mile) ecosystem. “It’s a die-off,” said Professor Ove Hoegh-Guldberg, a climate scientist at the University of Queensland in Australia and chief scientist at The Great Barrier Reef Foundation.

☆ Coral bleaching: Ocean heat is driving a mass bleaching event, and it could be the worst on record

CNN —Coral reefs around the world are experiencing a mass bleaching event as the climate crisis drives record-breaking ocean heat, two scientific bodies announced Monday — with some experts warning this could become the worst bleaching period in recorded history. If ocean temperatures don’t return to normal, bleaching can lead to mass coral death, threatening the species and food chains that rely on them with collapse. Professor Ove Hoegh-Guldberg, a climate scientist specializing in coral reefs based at the University of Queensland in Australia, predicted this mass bleaching event months ago. In February, scientists at the Coral Reef Watch program at NOAA added three new alert levels to the coral bleaching alert maps, to enable scientists to assess the new scale of underwater warming. Bex Wright/CNNIn mid-February, CNN witnessed extensive coral bleaching on Australia’s Great Barrier Reef – the world’s largest coral reef system – on five different reefs spanning the northern and southern areas.

This is the seventh mass bleaching event to hit the vast, ecologically important but fragile site and the fifth in only eight years. Covering nearly 133,000 square miles (345,000 square kilometers), the Great Barrier Reef is the world’s largest coral reef, home to more than 1,500 species of fish and 411 species of hard corals. Severe mass bleaching at the Great Barrier Reef had previously been observed in 1998, 2002, 2016, 2017, 2020 and 2022. Sunrise over the Great Barrier Reef at Lady Elliot island on October 10, 2019.

☆ Conditions are ripe for a global coral bleaching event: ‘Florida is just the tip of the iceberg’

NOAA, coral reefs, Florida Keys, coral reefs, coral bleaching, climate change, warm oceansCoral reefs off the coast of Florida are being hit by a mass bleaching event due to record high ocean temperatures, and early indications suggest a global mass bleaching event could be underway. The Sentinel climate research and monitoring site in the Florida Keys has recorded 100% coral bleaching since late July. There have been eight mass coral bleaching events that have impacted the entire Florida Keys since 1987, Manzello said. "We're talking about thousands upon thousands of miles of coral reefs undergoing severe bleaching heat stress," Manzello said. "Now, it's still way too early to predict whether or not there will be a global bleaching event, but if we compare what is happening right now to what happened in the beginning of the past global bleaching event, things are worse now than they were in 2014 to 2017."

Florida’s coral reefs are facing what could be an unprecedented threat from a marine heat wave that is warming the Gulf of Mexico, pushing water temperatures into the 90s Fahrenheit. The biggest concern for coral isn’t just the current sea surface temperatures in the Florida Keys, even though they are the hottest on record. The daily average surface temperature off the Keys on Monday was just over 90 degrees Fahrenheit, or 32.4 Celsius, according to the National Oceanic and Atmospheric Administration. Corals typically experience the most heat stress in August and September. “We’re entering uncharted territories,” Derek Manzello, an ecologist and the coordinator of NOAA’s Coral Reef Watch program, said.
