Global coral reefs shrink 9.5 percent
The report focused on the decline of global coral reef cover by 9.5% since the period between 1980 and 2009, following four major bleaching events since 1998 caused by marine heatwaves. It was based on the analysis of over 21 million observations from 36,800 sites across 124 countries, highlighting that each new bleaching event has led to significant decreases in coral cover, with an 8.9% decline expected during 2023-2024 compared to previous rates. The report also pointed out that climate change is the primary cause of coral bleaching, and that recovery periods are becoming shorter, with reefs able to recover by about 6% between 2017 and 2019 when given enough time. It emphasizes that time is running out for reefs to recover from increasing environmental pressures.
