Severe Heat and Cyclones Devastate Northern Great Barrier Reef Corals

The Great Barrier Reef has suffered significant coral loss due to extreme heat, cyclones, and flooding, with some areas losing over a third of their coral cover. The Australian Institute of Marine Science reports that climate change-driven heat stress is the primary cause, exacerbated by cyclones and freshwater flooding. The mass bleaching event is part of a global trend linked to rising ocean temperatures from fossil fuel emissions. Conservationists warn that the reef's resilience is nearing its limits, urging significant emissions reductions and a halt to new fossil fuel projects.
