The report of the New Australian government finds a decrease in coral through coral reefs due to “thermal stress caused by climate change”.
The great coral barrier in coral bleaching suffered, according to a new Australian government report, with an increase in ocean temperatures in 2024.
The Australian Institute of Maritime Sciences (AIMS) said on Wednesday that he had surveyed coral reef health between August 2024 and May 2025 and found “the most comprehensive” whitening since the records began in 1986, which were “mostly driven by thermal stress caused by climate change.”
The scientists also found that the coral cover decreased by nearly a third, to 26.9 percent, in the far south of coral reefs, as the southern reefs witnessed the highest levels recorded of heat stress..
“The decreases in the north and the largest south were in one year since the monitoring began 39 years ago,” the study authors wrote at the conversation.
Great Barrier REEF is described as the largest living structure in the world, and it is an extension of 2300 km (1400 miles) of tropical coral reefs that include an amazing set of biological diversity.
“The mass whitening events have become more intense and occurred at more hesitation,” said Professor Selena Stad, CEO of AIMS.
“The future of coral reefs in the world depends on reducing strong greenhouse gas emissions,” Steid said.
She added that the local pressure management and the assistance of coral reefs “adapting to the effects of climate change and recovery” were also important.
According to Unesco, which ranked Great Barrier Reef as a World Heritage Site, the ecosystem is home to the largest group of coral reefs in the world, including 400 types of coral.
It is also home to 1500 species of fish, 4000 species of mollusks, and 240 species of birds, as well as types such as Dugong and the large green turtle, according to UNESCO.

While United Nations experts say that the great coral reefs should be included among the World Heritage sites classified as “in danger”, the Australian government I pressed To keep it out of the endangered list, for fear that it will affect billions of dollars in the revenues of tourism it generates annually.
In a report released last week, the Climate Change Authority in Australia said that the opportunities to protect the Great Covering Cover barrier include the main countries that export the main fossil fuels that adopt low -emission alternatives and stronger work on climate pollutants, such as methane, which “contribute more to climate retreat in the short term.”
But Australia is still a The main source of fossil fuelIncluding charcoal from ControversialWhich is shipped through the great coral barrier.
The Authority’s report also indicated that about 93 percent of the excess heat in the air was absorbed by the oceans in the world, and that the ocean temperatures 2024 exceeded the previous record in 2023.
