It is estimated that 75% of the world's coral reefs are already threatened.
Regional variations in sea temperature can make all the difference between a coral reef suffering major bleaching or surviving as a refuge for corals, new research shows.
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.
Cuban and US scientists are forming partnerships to protect coral reefs and fisheries in both countries. But President Trump may soon announce steps to slow or reverse the US opening to Cuba.
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.
The British overseas territory faces an environmental crisis.
The government's latest report to UNESCO on the Great Barrier Reef paints a rosy picture.
Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Western Australia's super-corals are adapted to high temperatures, but even they didn't escape the recent bleaching event unscathed.
Months after record breaking coral bleaching, research teams are taking stock of the damage on the Great Barrier Reef.
Once upon a time dead coral was something to be celebrated on the Great Barrier Reef.
The marine reserves review has recommended major changes to the Coral Sea, but not for the better.
The oceans are filled with sounds produced by animals. However, a recent study shows that ocean sounds are diminishing due to nutrient pollution and ocean acidification.
Not all of the world's coral reefs are in dire straits. Reef fisheries tend to do better in areas with strong ownership rights, and where people are closely involved in managing their local reefs.
Could this new technology do for the microscopic marine world what the first telescopes did for the heavens above?
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?
A combination of factors – pollution, disease and overfishing – is harming corals but scientists have found clues to effective treatment by studying corals' microbiome.
