For the first time in its history, Australia has banned the development of coal mines under environmental laws.
The government on Thursday rejected plans for a new mine about 10 kilometers (6.2 miles) from the Great Barrier Reef. Environment Minister Tanya Plibersek said the project posed an unacceptable risk to the world heritage site, which was already in a hurry.
The mine's owner, controversial Australian billionaire Clive Palmer, has yet to respond to the denial. His company, Central Queensland Coal, proposed to build an open pit mine about 700km northwest of Brisbane that would produce both thermal and coking coal and operate for about 20 years.
Ms Plibersek had suggested last year that the federal government could block the bombing. After opening it for public review, his department received more than 9,000 submissions in 10 days - many calling for the project to be stopped.
The Great Barrier Reef - the world's largest coral reef system - has experienced four major bleaching events in the past six years due to sea temperatures and its outlook is "very poor", authorities said. • Warning following record coral cover on the Great Barrier Reef

Last year, the Queensland state government also recommended the federal government reject the plan, citing "significant" environmental risks.
Department of Minister Plibersek admitted that the discovery of sediment and water flows from open mines can damage the water supply in the water area. "I have decided that the negative environmental impact is too great," the minister said in a video statement on Wednesday.
Although the state government has previously rejected plans, this is the first time the state environment minister has used his authority to do so. Australia's Labor government - elected in May - has come under pressure from some to block any future coal and gas mining projects.
This country cannot help stop extreme climate change - or keep global warming below 1.5C rise this century - if it allows new mines, conservationists like the party The politics of the Greens said. Australia is a major global supplier of fossil fuels. When exports are taken into account, the country accounts for 3.6% of global emissions, but has only 0.3% of the world's population. Although the new government has increased Australia's emissions reduction targets by 2030, it has also said it will support any new fossil fuel projects that make a business sense.




Coral has recovered from heavy rains and bleaching events to record levels across Australia's oceans, a study has found. The northern and central parts of the water have the largest coral cover since monitoring began 36 years ago.
But the coral cover in the southern part of the lake has decreased. The new coral is fast-moving, meaning that growth can be quickly reversed by climate change and other threats, officials said.
Every year, the Australian Institute of Marine Science (Aims) studies the health of the water, using air surveys and divers to slowly move the boat. After his fourth whitewash in six years in March, Aims was very concerned ahead of this year's study.
"In our 36 years of monitoring the state of the Great Barrier Reef, we have never seen a bleaching event this season," said Paul Hardisty. • Mass bleaching events hit the Great Barrier Reef
Bleaching occurs when corals are stressed by hot water that kills the algae that live there, giving them color and life.
Only two human washing events were recorded before 2016. This year's bleaching event was the first to occur during La Niña, a weather phenomenon that typically brings cooler water temperatures.



The new results show that water bodies can recover if conditions allow, Dr Hardisty says, but "very chaotic and severe" conditions are becoming more frequent and long-lasting. • Why is the Great Barrier Reef in trouble?
The crown that eats the coral has also damaged the water by catching stars and storms that cause destructive waves. Much of the new coral growth - a species called Acropora - is particularly exposed to threats from the water, Dr Mike Emslie of Aims said.
"It means that... future crises may reverse the observed recovery in the short term,” he said.


The Great Barrier Reef has been a World Heritage Site for 40 years because of its "great scientific and critical importance" as one of the world's most biodiverse ecosystems. The Great Barrier Reef Marine Park Authority, which oversees the reef, says the outlook for the landmark is "very poor" due to climate change.
UNESCO, the UN organization of science and culture, said that not enough is being done to protect the rain.
