| 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. |

| ▲ | verelo an hour ago | parent [-] | | This kills me. I saw the reef for the first time around 2007. I went back twice, and the last time I was there (2017) I honestly couldn't believe what I saw. Wasteland? An under water desert? I don't have words for it, but I don't really want to go back because it hit me so hard. Our planet is dying and we're sitting here debating why/who and not doing anywhere near enough to fix it. I'm so glad we have space rockets, flying cars and drone warfare...but I'd trade it all in for the reef to come back. | | |

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. | |
| ▲ | mikepurvis 21 minutes ago | parent | prev | next [-] | | That's horrifying to hear. I also went on a multi day dive trip at gbr and the coral sea in 2007 and it was spectacular; I can't imagine going back and seeing it degraded. | |

If only we were just debating why/who! Thanks to Social Media, filter bubbles, and “alternative facts,” we are back to debating whether it is actually even happening or not. | |
| ▲ | kbutler 41 minutes ago | parent | prev | next [-] | | Happy to report the northern and central GBR coral cover is currently higher than any time measured before 2020. Southern is currently below its long-term average, but 2024 was a record high in coral cover. https://www.aims.gov.au/monitoring-great-barrier-reef/gbr-co... This doesn't mean everything is fine, but it is doing way better than 2017. | | |
| ▲ | grosswait 8 minutes ago | parent [-] | | Wow, I wasn’t aware of this. I’ve always read climate change as the primary driver for bleaching. If that is the case, do we know why/how they’ve recovered? |

| ▲ | dcrazy 2 hours ago | parent [-] | | I remember hearing that the concern with our best techniques for rescuing coral reefs is that they would create a monoculture, and monocultures tend to be very susceptible to specific diseases. |

| Only if they are clones - genetically identical. So not much use in practice, unfortunately. |
| |
| ▲ | smallerize 3 hours ago | parent | next [-] | | I think the article says they just haven't tested other cases. I wouldn't expect the symbiotic microalgae to be that picky. Edit - The article makes Okkef's point, I just missed it. | | |
| ▲ | ceejayoz 2 hours ago | parent [-] | | The article says otherwise. > Fragments from different species and even different animals of the same species did not fuse together, and so did not nurse the bleached piece back to health. |

| ▲ | kulahan 2 hours ago | parent | prev | next [-] | | Sounds like a solution is still well within our reach. Normally I wouldn’t suggest something as extreme as using cloning techniques to restore wild creatures, but of course it was extreme actions that got us here in the first place, so I think this balances it out. | | | |
| ▲ | idontwantthis 3 hours ago | parent | prev [-] | | We could create a bank of coral clones tagged to each individual location. |

| Some good news :) anything to bring back coral reefs |

| Could this also, have anything to do with, Nikola Tesla's resonance theory on dark matter and consciousness, in play in living matter? More intelligent individuals should look more into this field. |
| |
| ▲ | aappleby 2 hours ago | parent | next [-] | | No. Tesla's resonance theory has nothing to do with dark matter, consciousness, or living matter. | |
| ▲ | tcdent 3 hours ago | parent | prev | next [-] | | I'm all about the concepts you're presenting, but care to elaborate on how you think the corals relate? | | |
| ▲ | asjkff 3 hours ago | parent [-] | | Disclaimer: I am still finding my way in life, so take this theory with a grain of salt. New age movement, claim everything on earth is actually a hologram of the universe, experiencing itself. So perhaps, just being in close proximity with another coral, the hologram frequency was now more in tuned. | | |
| ▲ | rbn3 2 hours ago | parent | next [-] | | Since you mentioned you’re still finding your way in life: please be aware that the appeal of a lot of new age and „woo“ is that the act of noticing a pattern in nature, that feeling of „aaah NOW it makes sense“ is inherently pleasant and can become something you chase like a drug. These frameworks or schools of thought can provide a steady source of that feeling without necessarily being tethered to reality at all. Kind of like acid - very fun at times but catastrophic if you make it a core part of your identity. | | |
| ▲ | hmokiguess 29 minutes ago | parent [-] | | Well said, I have found myself in this place before in life and it can be quite dangerous |
| |
| ▲ | hmokiguess 3 hours ago | parent | prev | next [-] | | Why would the frequency of the healthy one win over the frequency of the non-healthy one though? I assume both would have their own frequencies, are you implying there's an order or tendency across frequencies? | | |
| ▲ | asjkff 2 hours ago | parent [-] | | Same reason, stem cells repair damage body cells, I guess. I am just glad coral can repair themselves. Thumbs up to the researcher. |

| ▲ | willy_k 39 minutes ago | parent | prev [-] | | You might be interested in Catholic theology + philosophy. It takes a LOT of background, and a lot of time to accumulate it, but you clearly have some already, and once you get comfortable with reframing terms that have a lot of societal baggage attached to simpler, honest understandings (for example, God, as a sky dude vs the universe as a mind), you can go so far. |

| ▲ | patmorgan23 2 hours ago | parent | prev [-] | | No that's ridiculous woo woo. It's just that some of the symbiotic algae from the healthy coral transfer over to feed and revive the sick coral. |
