As seas warm and acidify with climate change, corals worldwide are bleaching – but in the north of the Red Sea there is a ray, or rather reef – of hope.
Over the next 20 years, scientists estimate about 70 to 90% of all coral reefs will disappear primarily as a result of warming ocean waters, ocean acidity, and pollution.
Warm water can leave corals looking dead – but in some cases polyps still survive deep in the coral skeleton and in time they can return the coral to life.
The Allen Coral Atlas is building out a database - fed with satellite imagery - that can detect changes in coral reefs and hopefully help us better manage this dwindling natural resource.
Mass coral bleaching has altered the behaviour of species such as butterflyfish, a finding that identifies an early signal that fish populations are in trouble, researchers say.
