Great Barrier Reef bleaching would be almost impossible without climate change

This summer’s record-breaking coral bleaching on the Great Barrier Reef was made 175 times more likely thanks to climate change.

The bleaching hitting the Great Barrier Reef not only harms corals. As these close-up photos show, it also deprives many other species of a home and livelihood.

Coral Bleaching Taskforce: more than 1,000 km of the Great Barrier Reef has bleached

Bleaching has hit a huge swathe of the Great Barrier Reef, with many corals in the reef’s remote northern reaches now expected to die as a result of warm waters linked to this summer’s El Niño.

Great Barrier Reef bleaching event: what happens next?

Authorities have moved the Great Barrier Reef onto its highest alert level in response to widespread coral bleaching. Months of monitoring will now be needed to assess the ongoing damage.

High-tech fertilisers and innovation have to come to the Great Barrier Reef’s rescue

The latest Great Barrier Reef report shows some improvements to water quality over the past five years, but there’s still a lot to do on one particular problem: nitrogen.

Australia’s ‘other’ reef is worth more than $10 billion a year - but have you heard of it?

The Great Southern Reef covers 71,000 square km and contributes more than A$10 billion to Australia’s economy each year.

Not out of hot water yet: what the world thinks about the Great Barrier Reef

Australia was spared the ignominy of having the Great Barrier Reef listed as officially in danger. But comments from member countries of the World Heritage Committee show the world is still worried about it.

It’s time for the new Great Barrier Reef expert panel to wade into the issue

The government’s plan to save the Great Barrier Reef hinges on hitting a series of pollution and conservation targets within just a few years. A new expert panel will advise on how best to get there.

The Barrier Reef is not listed as in danger, but the threats remain

Whether it’s on the official “in danger” list or not, the Great Barrier Reef is clearly under threat. UNESCO has placed its faith in Australia, but without urgent action the problems will not go away.

Australia reprieved – now it must prove it can care for the Reef

UNESCO’s World Heritage Committee has spared Australia’s blushes by opting not to list the Great Barrier Reef as ‘in danger’. But it has also demanded that Australia make good on its plans to save it.
