#Coral #Bleaching is the whitening of corals caused by the expulsion of symbiotic algae (zooxanthellae) due to environmental stress, primarily rising ocean temperatures.

Coral bleaching vs mortality
When the ocean get too hot, corals expel the zooxanthellae algae that lives in their tissue.
In Western Australia, the damage to coral reefs including the World Heritage-listed Ningaloo has eclipsed any previous bleaching events.
These microorganisms give corals their bright pastel colours and disease resistance.
Their absence creates the bleaching effect many Australians have become all too familiar with.

Mass coral death at Ningaloo Reef
A fresh survey of eight sites along WA's Ningaloo Reef has revealed more than 60 per cent of corals have died.
Record water temperatures caused widespread bleaching last summer.
Of the 1,600 corals counted in March [last year], only 600 were still alive come late October.

Climate category, third place: Bleached
‘An unprecedented heatwave struck the coast of Western Australia during the summer of 2024-2025. We headed out to document the worst coral bleaching event ever recorded on the Ningaloo reef. White skeletons of suffering corals swept far beyond what our eyes could see. An estimated 60-80% of our reef was bleaching before our eyes.’

We usually associate rising temperature with #reef demise (e.g., #coral #bleaching). But it might be that temperature increase was fundamental to the establishment and formation of the Great Barrier Reef. Not a lot, just 2°C, but it brought carbonate production to the sweet spot to grow. But now #climatechange is shifting it out.

#Korallenriffe stehen durch die #Klimakrise vor dem #Aussterben. In nur 18 Monaten gab es vier globale #Bleaching-Ereignisse, bedingt durch steigende #Meerestemperaturen.
#Korallenriffe sind nicht nur ein ökologischer Schatz, sondern sichern auch die Ernährung von Milliarden Menschen. Um diese lebenswichtigen #Ökosysteme zu retten, sind globale Zusammenarbeit und lokale Maßnahmen gegen #Klimawandel und #Umweltverschmutzung unverzichtbar.

Over 97 Percent Of Bleached Coral Died At Lizard Island Reef After This Year's Event
The #GreatBarrierReef was struck by an extremely harsh mass #bleaching event this year, and it looks like parts of the reef are struggling to bounce back. Drone imagery of #LizardIsland’s North Point Reef shows that 97 percent of the bleached coral has died since the event earlier this year.

"The world is currently experiencing a global coral #bleaching event, according to #NOAA #scientists. This is the fourth global event on record and the second in the last 10 years... As the world's #oceans continue to warm, #coral bleaching is becoming more frequent and severe. When these events are sufficiently severe or prolonged, they can cause coral mortality"

"The world's #coralreefs are #bleaching. What does that mean?
Huge stretches of coral reef around the world are turning a ghostly white this year amid record warm ocean temperatures.
On Monday, the U.S. National Oceanic and Atmospheric Administration confirmed the world's fourth mass global bleaching event is underway - with serious consequences for marine life and for the people and economies that rely on reefs."

The Widest-Ever Global #Coral Crisis Will Hit Within Weeks
Rising sea temperatures around planet have caused #bleaching event that is expected to be most extensive on record. It is fourth such global event on record and is expected to affect more reefs than any other. Bleaching occurs when #corals become so stressed they lose symbiotic algae they need to survive. Corals can recover, but if water surrounding them is too hot for too long, they die.

"#Coral research finds bleaching impedes reproduction and hinders recovery
#Bleaching can suppress reproduction in a common coral species found in the Great Barrier Reef, hampering future reef replenishment, new research led by the Australian Institute of Marine Science (AIMS) and James Cook University (JCU) has identified."

Many #CoralReefs are dying. This one is exploding with life.
Scientists recently observed a rare phenomenon on a reef in #Cambodia that left them in awe — and filled them with hope.
By Benji Jones@BenjiSJones Mar 14, 2024
"Globally, coral reefs, which underpin commercial fisheries and protect coastlines from storms, have declined by half since the 1950s, largely due to #ClimateChange. Spells of extreme #MarineHeat break down the relationship between #coral and a type of symbiotic #algae that gives it both food and its vibrant colors. The coral turns white — a process referred to as #bleaching — and can then easily starve to death.
"The reefs in Cambodia and in the broader #EastAsian region, however, appear to be bucking this trend. Surveys indicate that they haven’t declined in recent decades, perhaps because they’re more resilient to warming. Their secret to survival may ultimately help safeguard ailing reefs elsewhere."
