Nearly all of Australia's coral reefs are at risk of being wiped out in less than two decades
There is NO evidence given for this. It's just a Warmist claim, possibly based on models but that is guesswork, not evidence
The idea that warming is bad for corals is completely unscientific anyway. Barrier reef corals are most diverse in the Torres strait, which is the WARMEST part of the reef. Like most living things, corals LIKE warmth
SHOCKING evidence has been released claiming that nearly all of Australia's coral reefs are at risk of being wiped out in less than two decades.
The report by the World Resources Institute claims that by 2030, 90 per cent of Australia's reefs will suffer from the overwhelming effects of climate change like warmer seas and acidification.
It also outlines the threat to the rest of the world's coral reefs, with research suggesting that many could be obliterated by 2050 due to pollution, climate change and over-fishing.
The report encourages Australia not to waste any time in fighting the prediction, particularly because of the impact reef degredation will have on tourism and the economy.
Dr Clive Wilkinson, the United Nations sponsored Global Coral Reef Monitoring Network coordinator, urged Australia "to be part of the global solution to climate change, as our reefs will suffer like others around the world and this will threaten the $5 to $6 billion per year that the Great Barrier Reef means to the Australian economy."
"Australians have no right to be complacent as the vast majority of our reefs will be seriously threatened by rising sea temperatures and increasing acidification in less than 20 years," he said.
Today, 40 per cent of Australia's reefs are under pressure from rising sea temperatures and other threats linked to climate change.
However, 75 per cent of the reefs are in marine protected areas, which is a contributing factor to the improvement in fish numbers and reef resilience.
On Lizard island, the reef is as good as scientists have ever seen it
I have reproduced below just a few factual bits from an article heavy with global warming prophecy. There is a feeble attempt to say that the thriving corals around the Lizard Island research station are not typical but no evidence is adduced to show that. It's just assertion.
Clearly, from the actual reports below, the various "bleaching" events have not significantly harmed the reef. The prophesied doom has not eventuated. The reef has been in existence for millions of years, surviving all sorts of weather events, so it has acquired the ability to bounce back from occasional harm
There’s a friendly atmosphere as researchers mingle at the station, often alongside large taps that run salt water into the fish tanks. The marine biologists talk about their research projects and plan when they’re next hitting the ocean. One of the best places to sink below the surface is North Point – about a 20-minute boat ride from the centre in rough wave conditions – where PhD candidate Matt Nicholson and Durham University Assistant Professor Dr Will Feeney are filming fish behaviour.
Between dives, the pair say the reef is as good as they have ever seen it. Five years ago, this area was severely impacted by mass coral bleaching and cyclone events. Now, it teems with wildlife: parrot fish with their distinct beak-like mouths nibble at bits of coral, schools of blue-green and yellow damsel fish dart around, while Feeney spots a group of six harlequin filefish fighting. They stand out among the other fish because of their aqua and orange spot colouring and long, snout-like faces. Not long ago, it would be rare for Feeney to have spotted any.
Another sign that the reef is recovering is the branching coral that appears every few metres or so. Its budding branches give scientists hope this patch of the reef is slowly recovering from the past six years which have been filled with four mass coral bleaching events since 2016 and tropical cyclones. The 2021 and 2022 summer was the first time the reef had bleached during a La Nina year.
The Australian Institute of Marine Science (AIMS) listed the outlook for the reef’s health as “very poor” in this year’s annual report, with the agency’s chief executive, Paul Hardisty, saying the increased frequency of mass coral bleaching events was “uncharted territory” for the reef following the fourth mass bleaching in seven years.
WWF Australia head of oceans Richard Leck said the recovery of the reef was patchy. In areas that had bounced back, including Lizard Island and the northern parts of the reef, recovery had predominately been of fast-growing coral which limits biodiversity. Some corals can take up to 100 years to grow and so as climate-induced events become more frequent, the diversity of the reef diminishes.
“This type of coral-dominated recovery is one that is highly susceptible to threats like coral bleaching and storm damage from cyclones. It is susceptible to Crown of Thorn starfish too.
However, he says the recovery in some parts of the reef should give people hope that the reef is resilient and that efforts to protect it are working. He adds that the government should also consider investing its next round of funding into limiting the environmental damage from pollution and sediment run-off from agriculture.
