Half of World's Coral Reefs Hit by Bleaching
11 Feb
Summary
- Over half of the world's coral reefs have experienced moderate or worse bleaching.
- 15% of global reefs have suffered significant coral mortality due to warming.
- Coral reefs prevent damage from waves, storms, and erosion.
Recent scientific analysis confirms that more than half of the world's coral reefs are currently experiencing moderate to severe bleaching. The study, which examined data from over 15,000 reefs globally, also found that 15% have suffered significant mortality.
Ocean warming is increasingly recognized as the main cause behind the heightened frequency, extent, and severity of coral bleaching events. This phenomenon is impacting reefs across the Atlantic, Pacific, and Indian oceans.
Researchers noted that the current Fourth Global Coral Bleaching Event, which began in early 2023, is even more severe than previous occurrences. This ongoing crisis threatens the irreversible degradation of these essential marine ecosystems.
Beyond their ecological importance, coral reefs provide crucial coastal protection by acting as natural barriers against waves and storms. They are also vital for biodiversity, supporting nearly one-third of all marine species.
