Coral in the Great Barrier Reef is once again bleaching, with water temperatures up to 3°C higher than normal in some places.

The reef is suffering environmental conditions that are so extreme, scientists are struggling to simulate these scenarios in laboratories.
Marine heatwaves will happen so often that reefs will struggle to weather successive bleaching events.
The package comes as the Morrison government tries to convince the World Heritage Committee it is making every effort to preserve the reef.
The rapid rate of species declines means we should trial potential solutions before it’s too late.
New research shows just 2% of the Great Barrier Reef remains untouched by bleaching since 1998. Its future survival depends on how much higher we allow global temperatures to rise.
Academic research can shed light on crucial questions about what life on Earth will be like under the most plausible emissions scenarios. And a warning: the answers are confronting.
Friday’s decision from the World Heritage Committee doesn’t change the irrefutable evidence that dangerous impacts are occurring on the Great Barrier Reef.
Just because coral is dying, doesn’t mean marine life in reefs will end. New research found dead coral hosted 100 times more microscopic invertebrates than healthy coral.
Researchers found 16% of coral species have not been seen for many years. This finding is alarming, because local extinctions suggest global extinctions may be looming.
The development is significant for several reasons – not least that Australia’s progress under the Paris Agreement is being linked to its stewardship of the reef.
This is not an imaginary future dystopia. It’s a scientific projection of Australia under 3°C of global warming – a future we must both strenuously try to avoid, but also prepare for.
New research shows nature started its long road to recovery in 2020 – especially in NSW and Victoria. But overall conditions across large swathes of the country remain poor.
Humanity is destroying Earth’s ability to support complex life. But coming to grips with the magnitude of the problem is hard, even for experts.
New research involving CRISPR technology has furthered our understanding of corals’ gene functions. Specifically, it has revealed a mechanism underpinning how corals withstand heat stress.
There are fundamental knowledge gaps around coral in the Great Barrier Reef, including how many species live there and where they’re found. Our new study finally starts to fill those gaps.
Hundreds of organizations are working around the world to restore damaged coral reefs. New research shows that rapid ocean warming threatens these efforts.
They’re more used to taking visitors to the reefs, but COVID-19 gave tour operators time to help check the condition of the corals. What they found doesn’t bode well.
Reef fish vanish during marine heat waves, but may bounce back quickly on reefs that have few other environmental stressors.
While most corals turn ghostly white when they bleach, some turn neon purple. Scientists were baffled – until now.
