Coral Bleaching Occurring Too Frequently for Reefs to Recover, Scientists Say
Scientists say reefs are bleaching so often that hard coral cover has fallen 9.5% below historical averages and recovery gaps now average five to six years.
- On Monday, the Global Coral Reef Monitoring Network released a report finding that coral reefs lack sufficient time to recover between bleaching events, with intervals shrinking from decades to just five or six years.
- Rising ocean heat and pollution drive this decline, with lead author Manuel Gonzalez Rivero describing the trend as a "staircase of decline" and noting a steep change in coral cover since 2010.
- The 2023 bleaching event was the most extensive on record, impacting 77% of the world's reef areas, while living coral cover has fallen 9.5% compared with the 1980–2009 historical average.
- Pacific leaders gather in Palau on Aug 31 for the Pacific Islands Forum, where they are expected to coordinate climate priorities ahead of the COP31 conference later in 2026.
- David Obura, chair of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, warned that "delayed action risks locking in irreversible losses," urging immediate investment in resilience solutions.

Coral bleaching occurring too frequently for reefs to recover: Scientists - The Tribune
Coral reefs are experiencing bleaching events so frequently that they no longer have time to recover before the next one strikes, with global coral cover now well below normal levels and at risk of irreversible decline, scientists said on Monday. The world’s coral reefs sustain a quarter of all marine life, make coastlines more resilient […]
Worldwide, the hard coral stocks continue to shrink after every heat wave. A new report shows that there is hardly any time for regeneration between the bleaching. The ongoing climate phenomenon El Niño further aggravates the situation.
