Scientists at the Palau International Coral Reef Center estimate that it takes at least nine to 12 years for coral reefs to fully recover from mass bleaching events, according to research ...
After corals experience a bleaching event to increased temperature stress some reefs are able to return to their original, pre-bleaching state. [168] [169] Reefs either recover from bleaching, where they are recolonized by zooxanthellae, or they experience a regime shift, where previously flourishing coral reefs are taken over by thick layers ...
The NOAA coral reef authority declared the global bleaching event in April 2024, making it the fourth of its kind since 1998. The previous record from the 2014 to 2017 mass bleaching affected just ...
Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared Monday, a result of warming ocean waters amid human-caused climate change. Coral ...
Coral reefs are important ecosystems that sustain underwater life, protect biodiversity and slow erosion. They also support local economies through tourism. Bleaching has been happening in various regions for some time. In the world's largest coral reef ecosystem, Australia's Great Barrier Reef, bleaching affected 90% of the coral assessed in 2022.
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.
Marine scientists tracked coral colonies in a remote area of the Great Barrier Reef and found that corals previously more resilient to bleaching suffered devastating and fatal bleaching during ...
Water temperature changes or disease of the coral [56] can induce coral bleaching, as happened during the 1998 and 2004 El Niño years, in which sea surface temperatures rose well above normal, bleaching and killing many reefs. Bleaching may be caused by different triggers, including high sea surface temperature (SST), pollution, or other ...
