How the 2016 bleaching altered the shape of the northern Great Barrier Reef

The 2016 bleaching event resulted in 30% mortality on the Great Barrier Reef, with many corals dying of the heat before they bleached and the loss of branching corals creating less complex reef structure.

Our acid oceans will dissolve coral reef sands within decades

Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.

The Great Barrier Reef can repair itself, with a little help from science

Corals on the Great Barrier Reef that are tolerant to warmer waters can be used to help repair other parts of the reef damaged by recent coral bleaching events.
The southern Great Barrier Reef escaped both of the recent mass bleaching events. But time is running out. AAP Image/ARC Centre of Excellence for Coral Reef Studies, Tory Chase

The world’s coral reefs are in trouble, but don’t give up on them yet

Tropical coral reefs can be saved from climate change and other pressures, but the window of opportunity is closing. And reefs are guaranteed to be markedly different in the future.
Months after the bleaching event on the Great Barrier Reef, signs of the hoped-for recovery are scant. Kirsten Tidswell/Climate Council

The Great Barrier Reef’s ‘new normal’ is a forlorn sight

Member of the Climate Council this week returned to one of the areas of the Great Barrier Reef that was worst affected by this year's coral bleaching. What they found was far from encouraging.
We think of coral reefs as a diverse ecosystem, but each coral is an entire and complex microworld of organisms imperceptible to our eyes. Floriaan Devloo-Delva

What we have in common with corals and their unexplored microbial world

Just like humans, corals live with myriad microscopic organisms. We are just starting to understand this unseen world.

Healthy microbes make for a resilient Great Barrier Reef

A new study provides insight into coral-dwelling microbial communities and how they react to pollution, overfishing, and climate change. What does it mean for the Great Barrier Reef?
Malcolm Turnbull and his colleagues have pointed $1 billion of the government’s existing green energy funding towards the Great Barrier Reef. AAP/Lukas Coch

PolicyCheck: What are the parties really offering to save the Great Barrier Reef?

The Coalition has ramped up the race to fund the Great Barrier Reef's protection. All three major parties have promised hundreds of millions of dollars, but where from, and what will they be spent on?
