Sir David Attenborough has issued a call the save the Great Barrier Reef.
Bleached coral can take on luminously beautiful pink and purple hues - but don’t be deceived, these corals are under stress.
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.
Recent aerial surveys found huge amounts of coral bleaching in the Great Barrier Reef.

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.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

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.

Right on cue, coral bleaching has struck the Great Barrier Reef, as the world's third mass bleaching event continues.
Don’t dismiss what science has to say about the fate of coral reefs.
Marine scientists have been accused of being biased towards 'doom and gloom'. But it's not bias if the outlook for coral reefs really is gloomy.
Corals grow better in the more alkaline ocean conditions that existed in pre-industrial times.
By artificially going 'back in time' to more alkaline ocean conditions, researchers have shown the damage that ocean acidification is already doing to the Great Barrier Reef.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
Land clearing rates in Queensland tripled since 2010.
Land clearing in Queensland has tripled in the past five years.
Nutrient runoff is one of the major contributors to crown-of-thorns outbreaks.

Despite 15 years of concerted action by the Australian and Queensland governments the health of the reef is not improving and in fact may be continuing to deteriorate.
Soon the oceans will be too warm to support thriving coral reefs.

Corals are experiencing only the third global bleaching event in recorded history, caused by warming seas. But worse is yet to come.
Nitrogen pollution is one of the factors driving outbreaks of crown-of-thorns - giant starfish that devour the reef.

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.
Diving in Indonesia’s Raja Ampat Marine Park to see these clownfish will cost you more than before – but for good reason.
Diving in many parts of Indonesia, Thailand and Malaysia now costs a little more than it used to – but you might be happy to discover why.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.

The World Heritage Committee’s deliberations involved far more than a simple tick for 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.
