- Record ocean heating is causing the world's fourth mass coral bleaching event, jeopardizing marine ecosystems, the US's oceanic and marine life body has reported. BBC News
- Around 54% of the ocean waters with coral reefs have experienced such heat stress, the National Oceanic and Atmospheric Administration (NOAA) has said. Guardian (LR: 2 CP: 5)
- Up to 75% of the 1,001 reefs inspected of Australia's Great Barrier Reef have reportedly been affected — 10% of the damage being extreme. The sources say bleaching has affected some 2,300KM of the ecosystem. The Sydney Morning Herald
- Scientists say this is the fifth mass bleaching of the Great Barrier Reef since 2016, and is consistent with similar reports of bleaching from across the world. NBC (LR: 2 CP: 4)
- Bleaching occurs when corals expel tiny photosynthetic algae in response to rising ocean temperatures, causing the normally colorful marine invertebrates to turn white. NBC (LR: 2 CP: 4)
- It began in the Caribbean in 2023, where bathers reportedly found the waters as warm as a hot tub. It has since progressed to affect more than half the world's coral. BBC News
Narrative A:
- Researchers have found that shading can significantly reduce coral reef bleaching. Different species of corals respond variably to shading interventions like artificial coverings and seawater fogging systems. This strategy still offers potential solutions to bleaching. Further research and development is needed to scale up these interventions effectively and help coral reefs withstand climate change.

Narrative B:
- The climate crisis's hidden threats, such as coral damage, paint a grave picture. Climate change must be addressed as a whole — not through singular solutions — with a focus on reducing pollutants and transitioning away from fossil fuels. Scientists and activists are striving to save reefs through interventions like coral nurturing, but more must be done to protect coral reef, marine biodiversity, and the well-being of millions worldwide.

Narrative C:
- Reports had previously suggested in 2022 that ocean warming had led to mass bleaching of the Great Barrier Reef. Yet a subsequent survey revealed a significant recovery. This challenged dire predictions and showcased the reef's resilience, all while highlighting its complexity. This episode should caution us against premature conclusions overstating the extent of irreversible damage.

- There's a 15% chance that the International Maritime Organization will permit more sulphur oxide pollution by 2030, according to the Metaculus prediction community.
