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.
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.
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.
Every year buoyant bundles rise from a spawning coral, giving the impression of an upside-down snowstorm.
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?
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 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.
Mining social media posts from tourism hotspots such as coral reefs could turn tourists into environmental citizen scientists without them even realising it.
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.
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.
The Great Barrier Reef has avoided being listed as "in danger" by UNESCO. But celebrating this is dangerously short-sighted.
Politics podcast: Anna Krien on the climate wars.
Anna Krien's latest Quarterly Essay explores the debates on climate change policy in Australia and the ecological effects of not acting.
A full valuation of the Great Barrier Reef leads to a number so high it is essentially not worth considering in economic terms.
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.
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.
As the Great Barrier Reef suffers a second wave of mass bleaching, there is a way to get involved.
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.
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. Without greater action on climate change and water quality, its World Heritage status could be listed as "in danger".
