The worst coral whitening on the Western Australian Reefs

Scientists say the world -famous coral reefs along the coast of Western Australia (WA) suffered the worst whitening after scientists say that the “largest” state “sea wave”.

Since August and this in May, warmer water temperatures led to significant thermal tension at the reefs, resulting in many corals kicked out algae, which gives them life and color – a process called whitening, which is often deadly.

Damage – for assessment – these months – cover 1500 km (932 miles) and include areas previously intact climate change.

Coral reefs worldwide suffer from two-year worldwide coral events due to record high ocean temperature.

Usually eight weeks of thermal stress are enough to destroy corals, and early estimates have shown that many reefs suffering from 15 to 30 said that the Maritime Scientific Agency in Australia.

“The duration and intensity of thermal stress and its mark in several regions is what we have never seen in most reefs in Western Australia before,” said James Hilmur of the Australian Maritime Science Institute (AIMS).

In the new report, AIMS researchers found that the 2024-25 year season was “the hardest whitening of coral” for the coral reef coral reef both in the northwest and central reef.

“The districts that gave us hope because they rarely had or did not whiten – like Rowly Schles, North Kimberly and Ninghal – this time they suffered hard. Finally, climatic heating caught up with these reefs,” he said.

Ningaloo Reef is a website that lists the world heritage, as well as the great barrier reef on the east coast of Australia, which in recent years has suffered from major coral whitening.

Last week, New Report A large barrier reef is revealed – the world’s largest coral system, which lasts more than 2300 km (1429 miles) – has survived the largest decrease in corals for almost four decades.

Federal Environmental Minister Murray Wat told the Australian broadcast corporation that Ningaloo’s coral damage “emphasizes the need for Australia and the world to take urgent measures, including pure zero emissions.”

Climate change means that events whitening becomes more frequent, more intense and more common, which, according to D -R -Gilmore, gives coral reef – which needs from 10 to 15 years to recover – little time to bounce back.

“Climate change caused by carbon emissions remains the biggest threat to our coral reefs and all reefs in the world,” he said.

Earlier, the UN warns that even if the world limits the global temperature to 1.5C above the industrial level, 70 to 90% of the world tropical coral reefs are killed.
