Coral gets its color from algae called zooxanthellae, which it depends on for photosynthesis.
Bleaching is actually due to the coral expelling those algae. Bleached corals are not dead, and remarkably they can not only let the algae in again but can also select a different algae species to cultivate (changing colour in the process)!.
This is thought to be a deliberate survival strategy to optimize the species of algae under different conditions (Adaptive Bleaching Hypothesis).
Bleaching is caused by the same stressors (like high temperature) which kill coral, but bleaching itself is not death of the coral.

Due to the coral or due to the algae? Put another way, could we engineer UV resistance into the algae?
booi 6 hours ago [-]
It's not UV that's the problem but heat. We could possibly cultivate algae that are more heat resistant?
skew-aberration 6 hours ago [-]
I'm not an expert, but yes we can and we do.
And so does the coral!
If a species of algae cannot handle high temperatures without generating chemicals like hydrogen peroxide which trigger the bleaching, then that species is ejected sooner and more frequently during warmer months, creating selective pressure for species that can.
To survive these conditions without getting ejected, the algae need to essentially run their photosynthesis process more slowly. They produce less chlorophyll per cell and create sacrificial 'photoprotective carotenoid pigments' which act like sunscreen and dissipate that potential sunlight energy as useless heat (coral has a few tricks too fluorescent proteins).
So the coral is actually in a delicate balancing act, selecting the most aggressive/productive algae which won't also try to kill it during summer. Corals will learn to be more conservative in their selection and algae will get more conservative themselves. We want this process to happen quickly enough so that we don't lose coral coverage and diversity in the coming decades / centuries, but we can be confident that on longer timescales the coral will adapt, assuming we don't get runaway warming.
dillydogg 6 hours ago [-]
This is actually in process, though my understanding is that it doesn't seem to keep up with the pace of ocean temperature rise.
Having been a diver on the Great Barrier Reef numerous times, the scale of bleaching events means that there is often no non-bleached neighbour for vast distances. Healthy propagation rarely occurs before the brown sludge sets in, then its game over.

It's really just climate change. (Ocean warming is what causes bleaching.) Luckily, since the 80s we've had the technology to generate energy without releasing greenhouse gases. I wish more people knew about the harms caused by climate change because maybe if they were they'd be more interested in preventing them.

The things you have to trade to get the reef back are not usually the things you want to trade. Otherwise, we could happily trade those things. It's not like there are that many people making space rockets, after all.

skew-aberration 7 hours ago [-]
Corals are killed en masse by other events, particularly cyclones. These have a much bigger affect on coral coverage, in the short term, than ocean temperatures / bleaching (which is transient and more localized).
Bleaching is not death of the coral, it is the expulsion of algae (typically in high temperatures). The coral can find a different species of algae, or the algae can return once temperatures drop.
There are corals living in regions of the ocean with different temperatures, so it is not that high temperature alone would kill all coral, but populations adapted to a given region (like north vs south GBR) are being affected by the speed of the changes.

Not necessarily but they do measure diversity too, and it has not changed dramatically.
Typically the biggest change in diversity is due to cyclones which kill of the delicate and fast-growing corals like staghorns, which are also the fastest to grow back.

Anecdotally I was also there around 2006/2007 - somewhere near Cairns - and the part I saw was esentially dead, not just bleached. It really depends on where you go.
Btw since many in this thread mention ocean warming I want to mention that after having followed this for many years, and observed changes first hand in different parts of the world, my conclusion is that the main factor is direct human influence, not something more abstract like global warming. Especially water pollution as a result of agriculture, unchecked population growth and tourism.
One of the problems is all the people who say they love the reefs want to go where the reefs are still intact, after other parts have already been destroyed. Which then puts even more pressure on those last remaining healthy reef systems. Just talk to divers and listen to the exotic locations they travel to these days. I think many aren't even aware they're part of the problem. Or maybe they subconsciously shift the blame. Reefs are usually healthiest where there are no or very few people around.
