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 was struck by an extremely harsh mass event this year, and it looks like parts of the reef are struggling to bounce back. Drone imagery of ’s North Point Reef shows that 97 percent of the bleached coral has died since the event earlier this year.

Australia's Great Barrier Reef suffered mass coral bleaching in 1998, 2002, 2016, 2017, 2020, 2022, and 2024.

#ClimateCrisis: NOAA confirms fourth global #CoralBleaching event phys.org/news/2024-04-noaa-fou

"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."
