Some three-quarters of Australia's famed Great Barrier Reef is suffering from coral bleaching, authorities said in a report on Wednesday, days after climate scientists warned the condition was blighting such reefs worldwide.
At least 54 countries and regions have experienced mass bleaching of their reefs since February 2023 as climate change warms the ocean's surface waters, the US National Oceanic and Atmospheric Administration (NOAA) has said.
"The Great Barrier Reef is an incredible ecosystem, and while it has shown its resilience time and time again, this summer has been particularly challenging," said Roger Beeden, of the Great Barrier Reef Marine Park Authority.
"Climate change is the greatest threat to the Great Barrier Reef, and coral reefs globally," added Beeden, the chief scientist of the Authority, which manages the area.
Coral bleaching was observed on 73% of the surveyed reefs in the park, the Authority said in its report, according to Reuters.
Bleaching is triggered by changes in water temperatures that cause corals to expel the colorful algae living in their tissues. But the corals cannot survive without the algae, which deliver nutrients to them.
On Monday, the world's top coral reef monitoring body, Coral Reef Watch, which is run by the NOAA, declared the fourth global bleaching event in the last three decades.

King Charles III will take part in his official birthday celebrations in a little over two weeks, as the monarch eases his way back into public duties while continuing to undergo cancer treatment, Buckingham Palace confirmed on Thursday.
The news came amid reports that Prince William’s wife, Kate, will miss a public rehearsal for the event as she, too, receives treatment for cancer. It remains unclear whether the Princess of Wales will attend the main ceremony, known as Trooping the Color, on June 15, Britain's Press Association reported.
Kate has revealed few details about her illness or treatment since announcing her cancer diagnosis on March 22.
Charles had been returning to public duties before Prime Minister Rishi Sunak last week called a snap election. That forced the king to postpone engagements that might divert attention from the campaign, raising questions about whether he would attend the birthday celebration.
Trooping the Color is a 460-year old tradition in which troops in full dress uniform parade past the king with their ceremonial flag, also known as their “color.”

Charles is likely to travel to the event by carriage with Queen Camilla and is expected to watch the Trooping ceremony seated on a dais, rather than on horseback as he did last year.
