Endangered green turtles like this one on Raine Island in Queensland’s far north face an uncertain future – one that depends largely on effective conservation measures.
With 99% of green sea turtles in the northern Great Barrier Reef hatching as females due to changing climate, the future for this species now depends largely on effective global conservation measures.
Corals near Lizard Island on the northern Great Barrier Reef experienced some of the worst bleaching in 2016.

The 2016 bleaching on the Great Barrier Reef was the worst on record. Now a new analysis points the finger squarely at human-induced warming, and warns that the entire reef's future is at stake.
Some reefs are strong sources of coral larvae.
A new study identifies dozens of individual reefs on the Great Barrier Reef that are especially important for coral larvae dispersal and which could help the entire ecosystem bounce back.
During mass spawning events coral young rise from their parents to ocean surface.

Would you pay more if you thought it would help?
Is Australia undervaluing its most valuable natural asset by only charging $6.50 a day to visit the Great Barrier Reef? And would it help if tourists were asked to pay more?
How the Great Barrier Reef can be helped to help repair the damaged reef.
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.
Water quality is one of the major issues that threatens the Great Barrier Reef’s health.

The updated plan for improving water quality on the Great Barrier Reef still doesn't address the need to curb intensively farmed crops such as sugar cane, and to enforce existing environmental laws.
Social media posts, such as this image uploaded to Flickr, can be repurposed for reef health monitoring.

Mining social media posts from tourism hotspots such as coral reefs could turn tourists into environmental citizen scientists without them even realising it.
Parts of the Great Barrier Reef’s outer reefs can form a natural barrier to coastal recession, thus protecting urban centres.
Coral bleaching on the Great Barrier Reef could lead to increased vulnerability of Queensland coastal cities and towns, and not only through its impacts on the tourism industry.
Dozens of reefs around the world have bleached in the past three years, of which the Great Barrier Reef was merely the most high-profile.

Amid fears for the world's coral reefs, the UN World Heritage Committee has issued its most wide-ranging statement so far on protecting heritage sites from climate. But the problem doesn't end there.

Anna Krien's latest Quarterly Essay explores the debates on climate change policy in Australia and the ecological effects of not acting.
How do you value the Great Barrier Reef?
A full valuation of the Great Barrier Reef leads to a number so high it is essentially not worth considering in economic terms.
The southern Great Barrier Reef escaped both of the recent mass bleaching events. But time is running out.

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.

South African economist is one of leading voices questioning the way we relate everything to a single statistic.
This year’s bleaching has mainly affected the Great Barrier Reef’s central region.
For the first time the Great Barrier Reef has been hit by mass bleaching in consecutive years, with only the reef's southernmost stretches having escaped both events unscathed.

The Great Barrier Reef is in crisis, as a second wave of coral bleaching hits. But the system of bodies and laws that protect it are getting more complicated – and less productive.
Hundreds of thousands of crown-of-thorns starfish have invaded North Queensland, devastating reefs.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
The Great Barrier Reef is bleaching again, in its first back-to-back mass bleaching event.
The Great Barrier Reef is bleaching again. Without greater action on climate change and water quality, its World Heritage status could be listed as "in danger".
