Great Barrier Reef

A scientist told "Newsweek" he was shocked to find some and coral communities have vanished completely since 1928.

"We simply believe that human life must be prioritised over the lives of sharks," head of the state government of Queensland, Australia, said.

It is clear that despite management efforts at local, regional and national levels, a significant number of threats to the reef are getting worse.

"The tourism industry, desperate to maintain tourist numbers, is looking beyond the natural beauty of the reef because it's not quite what it was," said dive operator Tony Fontes.

"The window of opportunity to improve the reef's long-term future is now," the report urged.

"The presence of corals in these extreme mangrove habitats challenges our understanding of the conditions some corals are capable of living in," researcher Emma Camp said.

Ambitious reef-wide health check could provide valuable information to save the largest barrier reef.

"Global warming is happening. As a society, we need to understand how species and ecosystems will respond to such change," said study author Lewis Jones.

Climate change is one of the greatest threats facing coral reefs around the world today.

Recent heavy rain in Australia has washed sediment and harmful chemicals into rivers that flow into the sea where the reef is located.

Deep-water seagrass covers an area twice the size of New Jersey and stores 28 million metric tons of blue carbon.

Coral reef resiliency after back-to-back marine heat waves has given scientists some hope.

Coral reefs around the world are facing a number of threats which are devastating coral populations.

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.

NOAA experts predict coral reefs in Florida, Hawaii and the Caribbean will be heavily impacted by global warming effects as soon as this summer.

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