About three quarters of the world’s reefs had not previously been mapped in this kind of in-depth way, and many not at all.
“Natural World Heritage sites are amongst the world’s most precious places, and we owe it to future generations to protect them,” IUCN Director-General Bruno Oberle said.
The 345,400 sq km World Heritage-listed coral network has been devastated by four coral bleaching events since 1998.
Over the 6 decades past, recent warming was 450% that of earlier warming — a big increase in rate of climate change effects.
The Amazon Reef is one of the world's largest reefs but its existence became known only in 2016.
Fish and coral have a codependent relationship, the fish rely on the reef to evade danger and lay eggs.
A 1.5 degree Celsius rise in global temperatures could see 70-90% of Earth's coral reefs vanish.
Unlike corals that undergo bleaching, halos are formed when corals are healthy and thriving.
Healthy corals need 10 years to recover after major damage — ten years they probably don't have.
The insides of a particularly long-living genus of corals, Porites, led to the new finding.
Corals can recover if the water temperature drops and the algae are able to recolonise them.
Coral reefs aren't facing a threat just from global warming, but also damage from rats, study finds.
The government should support and use the findings of such long-term monitoring.
Australia's iconic Great Barrier Reef has experienced widespread coral decline and habitat loss than previously thought
Australia's Great Barrier Reef has almost fully recovered from the worst coral bleaching ever known in recent history, authorities said on Monday.
The massive drop in visitors due to coral bleaching can lead to a loss of 1 billion Australian dollars in income, and 10,000 tourism jobs, the report said.
Improving the quality of water in the Great Barrier Reef in northeastern Australia requires around $11,571 billion over the next decade, according to a government study released on Thursday.
Offering a glimmer of hope to those managing the impact of bleaching on the world's coral reefs, a new UN report has found that part of the ecosystem may survive in barely known deeper environments, known as mesophotic coral ecosystems
Warm ocean temperatures have caused large expanses of coral to bleach in the pristine reefs northwest of Hawaii's main islands, scientists said.
