Australia’s next government may be Great Barrier Reef’s last chance after sixth mass bleaching, conservationist says | Great Barrier Reef
The great coral barrier was shown by the sixth widespread Coral bleaching event Since 2016 of this summer-the second time that the largest coral reefs in the world have seen a apparent blow in successive years-according to government authorities.
The reaction of scientists and the wealthy of the two preservatives to Khaza was that bleaching is widely – driven by global heating – became nature, as one of them said that the state of Australia coming from the government may be the last natural shot to survive.
“It is terrible,” said Professor Terry Einsworth, of the University of New South Wales and Vice President of International. Coral Coral reef community.
“The influence on coral reefs is a successive and severe bleaching events now a decade for a decade is mainly changing nature and the ecosystem of coral reefs.”
the Large reef barrier Marine Park Authory released an update on Wednesday, saying that the data indicates that REEF had witnessed a “wide -scale whitening of coral reefs” across the north and Al -Faqis in the north.
The update said: “This event is the sixth since 2016, and although it is less comprehensive than the coral whitening event in 2023-24, this is the second time that coral reefs have suffered from large-scale bleaching events through the successive summer.”
And the authority said in Compatible report The “whitening of the severe and widespread coral reefs” was caused by marine heat waves led by the climate crisis.

What is coral whiten?

Coral bleaching describes a process in which the coral animal is expelled algae that lives in its tissues and gives it color and a lot of nutrients.
Without algae, a skeleton of coral can be seen through its transparent flesh, with the appearance of a pesticide appearance.
Coral reef whitening causes large areas, and noticed for the first time in the eighties of the last century around the Caribbean, due to the high temperatures of the ocean.
Some coral reefs also display the colors of fluorescent under pressure when they launch a light nominating tincture. Sunlight also plays a role in bleaching bleaching.
Coral reefs can escape bleach if the temperatures are not extreme or very long. But extremist sea heat waves can kill coral reefs.
Coral reef whitening can have effects and gestures, including increased disease exposure and reduced growth and reproduction rates.
Scientists say that the gaps between bleaching events have become very short that they do not allow coral reefs to recover.
Coral reefs are one of the ecosystems of the planet at risk of global heating. Coral reef supports fisheries that feed hundreds of millions of people, as well as support for the main tourism industries.
Great Barrier Reef has suffered in Australia – from seven mass whitening events since 1998, including five in the past decade.
The previous bleaching occurred on its back on the great coral barrier in the summer in 2016 and 2017.
Last year’s whitening was the most widespread. Subsequent investigative studies in the months that were found after that Record the annual losses in the coral cover in several regions.
The Albanian government has previously made a budget of $ 1.2 billion to save coral reefs until 2030, but there was no new money in the latest budget for its recovery. Last week, the Labor Party pledged 10 million dollars for coral reef projects.
Until now, the decline in coral reefs was not one of the topical issues of the elections that he discussed in detail, either the Prime Minister or Peter Daton, whose mother condition is. Queensland.
The Authority said there is also evidence that the floods resulting from standard rains in Queensland during the summer had been damaged by coral reefs near coral reefs near the beach in the central and northern regions.
“It will take some time to understand the extent and effects of these climate -based events,” the authority said.
Coral reefs were also exposed to the Australian heritage list on the coast of Ninjo in West Australia. Extreme levels of whitening and heat stress since February.

A study last year found that temperatures on the great coral barrier were now in Heat in at least 400 years.
Bleaching in Ningaloo and Great Barrier Reef was part of Fourth global group whitening event This reached 83 % of coral reefs from planets across at least 82 countries and regions between January 1, 2023 and April 10, according to US government data.
“The bleaching is now almost almost every year. People are not affected by it as it was because it has become the new natural and does not hesitate to resonate the way it is used to,” said Professor Morgan Bratchit, a coral reef expert at James Cook University in Townsville.
“The biggest cause of coral deaths is climate change. From the sorting perspective, this is where we must start. These effects will get worse until we do something serious on this topic.”
Richard Lake, the ocean head of WWF Australia, said coral reefs “screaming for climate work.”
“The whitening of the new natural coral has become,” he said. “Year after year, coral reefs are cooked by underwater heat waves. The next government’s mandate can be the last opportunity to give coral reefs an opportunity to fight.”
Simon Miller, a severe activist at the Australian Navy Preservation Association, said that coral reefs are still trying to recover from the mass whitening event last year.
“These reports continue to show the damage caused by climate change, but it must lead to a procedure. Monitoring is necessary, but it cannot be our response. Australia must quickly reduce climate pollution and stop new fossil fuel approvals.”
“The first thing that its Australian governments and Queensland governments must do is to adopt safe climate policies.
“This means 90 % reducing climate pollution by 2035 and stopping approvals for new fossil fuel projects. Without addressing the root cause of the problem, the health of coral reefs is exposed to the long term and flexibility at risk.”
