According to the new report, some of the Great Barrier Leaf have suffered the largest annual decline on the coral cover since the record began almost 40 years ago.
The Australian Maritime Science Research Institute (AIMS) said that the huge northern and southern branches of the Australian reefs had the most extensive coral bleach.
In recent months, coral reefs have been assaulted by tropical cyclones and crowns feasted in corals, but the main reason for heat stress driven by climate change, AMS said.
The goal warns that habitats can reach the tipping point where corals cannot be recovered quickly and to face “volatile” among the fatal events.
AIMS examined the health of 124 coral reefs between August 2024 and May 2025. We have been investigating since 1986.
Great Barrier ReEF is a wide range of tropical corals that accommodate biodiversity of tropical corals of 2,300 km (1,429 miles), often called the world’s largest living structure. Repeated bleaching events are once turned into a vast crowd of lively coral white.
Ningaloo, the second largest reef in Australia on the west coast of Australia, experienced repetitive bleaches, and this year, the two main reefs were the first to turn white for the first time.
Coral is essential for the earth. The nickname of the sea architect builds a vast structure that accommodates about 25%of all marine species.
The bleach occurs when the coral is stressed and the water that lives is so hot that it turns white.
The stressful coral will probably die if you experience more than 1C (1.8F) of more than 10 years of heat for two months. If the water is 2C higher, it can survive for about a month.
The abnormally warm tropical seawater has caused a wide range of coral bleaches in the sixth event since 2016 in 2024 with Great Barrier REEF and the first few months in 2025.
In addition to climate change, natural weather patterns such as El Niño can also play a role in mass bleach.
“I have experienced an unprecedented level of heat stress, which has been the most spatish and severe bleach so far.”
According to the report, all recovery can take several years and depends on future coral reproduction and minimal environmental disturbance.
In the latest AIMS survey results, the most influenced coral species was Acropora, which was vulnerable to the preferred foods of heat stress and crown’s starfish.
Dr. MIKE EMSLIE told ABC News.
“Great Barrier REF is a beautiful and symbolic place, and it’s really worth fighting. And if we can give a chance, it has shown a unique ability to recover.”
The Australian government’s Thor Crown’s Welcome Curling Program was a bit of success, which injected vinegar or bull bile to kill more than 50,000 starfish.
“Because of the vertical crown control, there was no potential, establishment, or serious onset of Thorn’s crown recorded in the central GBR reef in 2025.”
Bigs are unique to Great Barrier ReEF and can eat a vast amount of coral. However, since the 1960s, their numbers have increased significantly, and the nutrients of land -based agricultural outflows have been considered the most likely.
Richard Leck, a global environmental charity organization, says the reef is a “amazing stress ecosystem” according to the report, and scientists are concerned about what happens when the reef does not come out in that way.
LECK warned that some coral reefs around the world are already beyond recovery, and Great Barrier Leaf can suffer the same destiny without ambitious and quick climate action.
Great Barrier REF has been listed on cultural heritage for more than 40 years, but UNESCO warns that Australian icons are at risk of warm sea and pollution.
