Great Barrier Reef

Coral reefs around the world are coming under increasing environmental pressures.

But today’s threats are far more intense than those of the past.

By using a tool known as CRISPR-Cas9, scientists may be able to identify corals that are genetically predisposed to survive as the climate changes around them.

Rising water temperatures are killing corals—but researchers think we can stop the die-off.

The hungry critters are eating away at the reef and there's no good way to get rid of them.

The alarming problem jeopardizes the world's largest population.

But it can still be saved, scientists said.

Scientists discover special reefs that appear to be key to regenerating the system and may protect it from damage in the future.

The deep blue hole was spotted by Johnny Gaskell on Google Maps.

If all goes well, the giant triton snails—or even just their scent—could stand guard over the declining reefs.

Greenpeace said listing the World Heritage Site as endangered would have forced the Australian government to act on climate change.

Researchers found a lagoon system in New Caledonia with corals that can survive in hot, acidic and low-oxygen waters.

An ongoing study of their welfare delivers its latest alarming finding.

Two thirds of the coral reef—designated a world heritage site—have been damaged, according to aerial surveys.

Scientists warn it may be too late to save the Great Barrier Reef, which experienced the worst dying off of coral ever recorded in 2016.

Watch out, crown-of-thorns starfish.

Australia’s Reef is home to more than 6,000 species.
