400-Year High Ocean Temp Threatens Great Barrier Reef

The Great Barrier Reef is experiencing its highest sea surface temperatures in 400 years, driving unprecedented coral bleaching and threatening marine biodiversity, according to a new study published in Nature. The study reveals temperatures from January to March 2024 were 0.34°F (0.19°C) above the previous record, exacerbating coral bleaching. Scientists warn that urgent action is needed to reduce emissions and prevent further damage to this vital ecosystem.
