#Ecological baseline shifts, often because of external forcing. #Reefs are no exception to that, with warming and #sea level taking their toll, and the near-term fossil record allows us to track that and see how coral communities were before we got there.

#News: Corals in Crisis with 84% of the world’s #coral #reefs are experiencing the worst bleaching event on record, driven by #climatechange and record ocean temperatures.

‘Ticking timebomb’: #sea acidity has reached critical levels, threatening entire #ecosystems
#OceanAcidification has crossed a crucial threshold for planetary health, scientists say.
Ocean acidification, called "evil twin" of #climatecrisis, is caused when #carbondioxide is absorbed by ocean, where it reacts with water molecules leading to a fall in #pH of #seawater. It damages #coral #reefs and other #ocean habitats and, in extreme cases, can dissolve the shells.

There was this notion, that as things get warmer, corals will expand to higher latitudes. But that seems not to be the case. Corals are too slow, and #warming is too fast. Not great news for the future of corals #reefs.
Something also to remember when we look at past extinction events.

The Hawaiian Drowned #Reefs expedition was one of the coolest things #IODP did before the program ended. Now all the site reports and core descriptions are online.
(And I just need to get around to reading them)

... still sad I didn't get to join it.

A major #coral bleaching event is happening across the world’s oceans. Scientists say it has now affected about 84% of the world’s coral reefs. This includes many #reefs in the #Caribbean, which are showing clear signs of stress. https://www.thestkittsnevisobserver.com/caribbean-coral-crisis-84-of-reefs-under-threat/

More than 80% of the world’s #reefs hit by bleaching after worst global event on record
Reefs in at least 82 countries were exposed to enough heat to turn corals white. #CoralReefs are known for their high concentration of biodiversity that supports about a third of all #marine species and a billion people. Record high #ocean temperatures have spread like an #underwater wildfire over corals across the #Pacific, #Atlantic and Indian oceans.

Largest #coral bleaching event on record harms 84% of #global #reefs

Bleached coral dies when exposed to #heat stress for too long, threatening the bountiful #marine #ecosystem that depends on it for survival.

#CoralReefs around the world are losing their color at an unprecedented scale as a result of rising #sea #temperatures, marine scientists announced this week, w/ 84% of reefs exposed to bleaching levels of heat since 2023.

I have my own critique on the possible over-focus on #reefs sometimes, but the simple fact is, today and across the #Phanerozoic, reefs have been loci of #biodiversity hotspots.
