Are Corals COOKED in THE LAST PARADISE when its so HOT?!

[@Leo555ZZZ]

Years ago I thought it strange to claim that warmer water on the GBR will cause damage , when coral reefs thrive in significantly warmer water in other places. It is clear that climate change alarmists are willing to blame any damaging event on climate change which they then claim to be caused by human activity. Great video , thanks to all those involved.

[@reefrebels]

Yes exactly , its a weak argument the climate alarmists use

[@Llamamagic2024]

Yes, thanks Peter for a consistent message of calm rationality

[@gbsailing9436]

Thanks Peter for keeping up the pressure on our politicians. Don't let me continue to scare us into thinking the GBR is doomed! Perhaps you could do a show on the effects of Urea on corals and help publicise that so that the public can be better informed about using toilets when visiting the reef as opposed to relieving themselves in situ while snorkelling.

[@jules2545]

Urea is utilised by bacteria and then the bacteria is used by corals as a food source, think of fish pee.

[@stephenpelletier8947]

Thanks for your efforts. Love seeing this as a one-time reef keeper. It's not emphasized enough that coral diversity is highest at the equator. I suspect that's more from the higher insolation rather than the higher temperature, but either way coral thrives at higher temperatures than the GBR sees. I also applaud your pointing out how important coral sporulation is to coral diversity, resilience, and health. Few folks have any idea that coral also reproduces sexually and propagates to establish new colonies across long distances. That's what's allowed them to survive and thrive for hundreds of millions of years in the face of enormous planetary changes up to and including extinction events. They are very resilient indeed.

The “Fragile Reef Hypothesis”. It’s amazing how so many hypotheses are lazily born from what appears to be flat ignorance.

[@TXDude]

This is what 'science' has become. Toss out a guesstimate in an assertive manner and leave it for your peers to replicate or refute. They no longer do that because they're busy throwing out their own guesstimate. So the 'connsidered opinion' becomes fact until someone wants to challenge it.

[@druspork7737]

A few years back I visited Lady Eliot Island (resort). Full of climate placards under the guise of "education". Claims that the aquatic life would rapidly diminish under warming. It struck me, that being on the very far south of the GBR, lethal warming would result in species following cooler conditions (to the south) - if so actually a rapid increase in life might indicate warming. Ditto here with equatorial reefs and the GBR.

Keep it up Peter, 👌

[@awakennow5852]

Im 59 and have regularly dived the outer barrier reefs, Ive seen natural infestations of COT starfish and refuction of various species due to illegal overfishing, but coral bleaching etc is a completely natural ocurrence. It could be argued that fringing inner reefs are damaged by ag runoff, but even this i find hard to vouch for. After reading the british royal comission report into climate change, and studying various ice core reports, i am definately inclined to agree with CC being a natural occurence, relative to the beginning of data recording

I can't recall making my request lol > I think it was a very well done presentation on the resilience of corral ecosystems. I doubt (and from much of the rhetoric I have seen) most have any understanding of just how "mobile" and resilient the inhabitants of reef ecosystems are. Over the 40 years I had out in the water I lost count of the number of corral spawns I have witnessed (Holds nose thinking about it. Messy, smelly little critters lol). I have watched it move around and change in familiar places over that period, Small bleach events and regrowth, storm events and regrowth etc. it's slower than the naked eye to see over one or two trips, but it is very dynamic as you watch it over a longer time period. I also think something that modern society has difficulty with (more recent decades) is the concept of geological time. Some events occur on a small time scale, others occur over very long periods. The geological time period encompassing the life and evolution of the reef as a whole is mind boggling. It is a fascinating environment to experience and watch over time, even in a very short human lifespan :) > Thank you for the effort on the video.

Some of the closer inner reefs (Cattle creak line to Rattlesnake Island line) as well as the closer sections that come out on very low tides out off Berildgie Beach (I not sure if that's how it is spelt. Can't even find the name on a map anymore) also have an amazing range of life to witness.

We live by the coral triangle, went diving last weekend and the coral was looking fine. Lots of species look similar to that of Aus. Temperature was a little warmer than NW Australian waters

[@reefrebels]

Yes exactly :)

[@Oliver-tx8dh]

Perfect video! Interestingly, we don't have much study about corals from the Coral Triangle, the most studied being GBR, the Persian Gulf, Hawaii and the northern Red Sea. In the Ice Ages, Coral Triangle is a coral storage facility for better times. It also has the largest biodiversity of zooxanthella in the world - clades C, D, A. Scientists have amazing results in experiments with corals, e.g. Acropora milleopora with super heat-tolerant zoox Durusundium from GBR at 32.5C for 15 days and were completely healthy. Most scientists can now only use their policy, in my opinion there should be scientific studies with more opinions and more perspective - this is the main problem of science today.

The "fragile reef hypothesis" is such a strange idea. Basically all living things are anti-fragile. This applies to individual organisms, including humans, as well a systems of organisms. To hypothesise that a reef system, or reef systems in general, are fragile is absurd. It would imply that they would have all been wiped out by the many adversities that they have faced over the eons.

[@PhilJonesIII]

I think there is some confusion sometimes between the ginormous reef systems and systems people run as a hobby. Fresh water fish are generally hardy enough to tolerate home systems. Saltwater systems are several levels more difficult to maintain. For this reason, keepers of saltwater systems tend to use high volume tanks to maintain stability. Yes, home systems are still delicate, the chemistry is more complex and can be destabilized easily and quickly. Natural systems are not because the sheer volumes of water constantly moving around. That's my take but, it could also be an excuse for them.

If it’s not temperature, is it acidification or sunscreen that causes coral bleaching? I went to Heron Island, quite a bit were bleached. Is it a seasonal thing?

The GBR often goes through cycles of bleaching and has been for ages, the important thing to note is it always bounces back with strong recovery. We did earlier videos that debunks ocean acidification kzbin.info/www/bejne/gXqzZ2eYeNCkbqc and sunscreen damage kzbin.info/www/bejne/gaDFYnqdiLeNgMU

Peter Ridd I'd like to hear your thoughts on this very important new study on coral adaptation. Study - Algal symbiont diversity in Acropora muricata from the extreme reef of Bouraké associated with resistance to coral bleaching The study shows not only that the corals in lagoon Bouraké have resistant symbionts, but are also adapted from previous bleaching events- Cladocopicum C1. From the study-Cladocopium is one of the most diverse genera in the Symbiodiniaceae with functional variation in symbiont thermal performances , and functional variation in gene expression across reefs . C. proliferum has already been described as a dominant symbiont species in HEALTHLY colonies of A. muricata from Bouraké collected coral samples housing C. proliferum in 2016, during the first documented HEAT WAVE reported in New Caledonia that caused widespread coral bleaching. It is therefore likely that corals in Bouraké, and their C. proliferum, HAVE PREVIOUSLY BEEN EXPOSED TO SEVERE THERMAL STRESS. Several heat-evolved (i.e. thermally selected) strains of C. proliferum were found to display faster growth rates and higher photosynthetic efficiency than their wild-type counterparts under elevated temperatures . Similarly, some heat-evolved C. proliferum strains also enhanced bleaching tolerance when in symbiosis with coral larvae and recruits . Previous studies have also demonstrated the improved thermo-tolerance and physiological performances of corals hosting C. proliferum in controlled conditions by testing the effect of temperature only. Our data provides new ecologically RELEVANT evidence showing that corals ALREADY HOSTING THERMO-TOLERANT C. proliferum are able to better face extreme conditions, and maintain host-related physiological traits, to the combined effects of high temperature, low pH, low oxygen, and variable salinity. I THINK THAT IT'S A GOOD SUBJECT FOR A VIDEO.

[@reefrebels]

Thanks. Interesting stuff. Just shows that corals are clever critters and able to deal with changing environment in remarkable ways.

[@rogerthat487]

I recall reading a study some time ago that explained coral bleaching in the context of periods of exposure at low low water associated with el nino la nina not ocean temp. I guess that didn't fit the narrative

[@Debbie-henri]

Is it possible that corals in different regions have evolved to tolerate differing temperatures - just as most other creatures, including humans have done? Bring someone from the Inuit tribe and throw him in the latest Italian heatwave, and I'd be surprised if he makes it through the day. Similarly, I would expect most marine animals to travel to more comfortable regions if the water in their usual haunts is getting too hot. Coral can't do that, and no one can deny that those pictures are of coral bleaching events. It is happening, there must be a reason, the bleaching of the GBR isn't going to be subject to pollution sensitivity - because there must be even more pollution in the Indonesian archipelago region. I don't see why it isn't impossible for the corals making up the GBR to be more temperature sensitive than ones around Indonesia, if temperatures are often a lot hotter there. The Indonesian ones have just evolved to tolerate it, the Australian ones haven't. Therefore, transplant Indonesian ones onto the GBR and see what happens.

I’m a layman but I don’t have to be a scientist to roll my eyes at the crap regarding the barrier reef as this dwiddle, delicate ecosystem. Just knowing that only a few thousand years ago it was often the shoreline of a far shallower ocean level, that it’s a barrier against the violent might of the Pacific ocean with massive cyclones, storms winds, wind & tide change that lifts and displaces millions of tonnes of sand and silt constantly etc etc Yet I have to listen to disingenuous twits who tell me that a trace of a trace gas is going to cook the water via reradiated IR when IR only heats the top of the water surface a few thousandths of a mm and is evaporated off ? Please , even a layman knows it’s the suns UV radiation that heats water not IR…. The best response I get to that logic is the modern incantation from the holy and infallible religion of ‘Scientism’ ..”But but but the SCIENCE.” The Great Barrier Reef is robust and resilient not a piss weak, over sensitive and delicate system …. you know, akin to a progressive’s emotional life 😏
