- REEF REBELS Episode 6: The Reef Climate Crisis
Is hot water really killing the Great Barrier Reef? Or has there been a little exaggeration?
Coral bleaching, far from being a death sentence for coral, is actually a remarkable adaptive response mechanism that allows them to cope with changing climates.

Interesting slant on what maybe happening with corals around the world. I have seen some beautiful coral reefs in equatorial regions and have often wondered if a little bit warmer waters might just cause/allow corals to spread further away from the equator.
Thank you.
Keep up the great work Peter, you are a legend !
Very informative Peter. Your presentation should be used as an essential education tool in schools.
Unfortunately the corrupt schools in australia re more interested to brainwash the children about the climate change SCAM and the other 52 genders.
Thank you for this. Clear, simple, logical. It’s no wonder they come after you.
Well that was an awesome way to spend a cpl hours. Up to date now, keep em up doc :)
Well done Dr Peter Ridd!
Just learning that coral bleaching is a natural phenomenon. Thanks mate . Weird times .
Cool thanks mate
Still the best and most important video of reef rebels.👌
Thank you Peter. Always informative.

I am being a little lazy by asking this without looking more deeply into the research myself. A common Doom and gloom argument is ocean acidification from CO2 absorption will destroy the reef.. We know that water, rain and the ocean is the largest collector of atmospheric CO2 and readily turned into carbonic acid. Many paint this as a devastating proposition for the GBR. We also know that lime/calcium will easily react with H2CO3 to produce calcium carbonate which the polyps use for the corral home creation.
Many of our northern rivers and streams have quite high concentrations of calcium compounds running off into coastal areas inside of the GBR.
My question:
Are there enough concentrations of calcium compounds such as calcium hydroxide making it to the reef regions to react with the carbonic acid in the coastal GBR waters to produce beneficial CaCO3 for the reef?
Keeping in mind that fresh and salt water does not easily mix, and our coastal currents tend to have a slight close to shore northerly flow. Obviously our GBR must obtain the billions of tones of CaCO3 from somewhere.
So I guess I am asking does the amount of calcium compounds from our rivers offset the oceanic H2CO3 concentrations in coastal reef (GBR) regions and bearing that in mind does ocean acidification have a noticeable negative, or positive impact on the reef?

P.S. Locals such as myself were quite aware of small patches of bleaching on the reef well before 1980 as well as spawning events, although we did not have an understanding of these events as we do today.
Great Question. I have completed an episode on "ocean acidifcation" that will appear in a month or two. So stay tuned. Regarding the effect of rivers on CaCO3, they are too small to effect the reef very much - the flushing from the dominates.
@@peterridd5844 Thank you. I look forward to that. It has been a question on my mind for some time. Obviously all of the corrals calcium carbonate comes from somewhere so there must be correlations/reactions/balances somewhere.

I have also read that ocean salinity is dropping to the lower limits of what salt water species can tolerate. I don't know if this is a world wide generalization or the scope of the claims with regards to individual oceans and have no validation of the claims. People don't offer references to the actual scientific studies any more when making these claims so it is difficult to check the claims.

When it comes to concepts of looking after our planet, and even the effects of climate variability etc. I do take notice, I just refuse (make every effort not to) to get caught up in the subjective, emotive climate doom and gloom rhetoric.

Again sorry for leaning on you, but it may offer video discussion points for you. You are doing well with the presentations and I am enjoying them. Even though I have spent most of my life on the reef and around marine science it's not really my forte. I am far more comfortable coding CPUs :)
We need to get you on Triggernometry or Prageru. God Bless you Dr. Ridd.
Thanks Dr. Ridd.
Dr. Ridd, why is there so little bleaching in raja ampat? Is it the huge range in temperature the water there experiences every day? What needs to be done to preserve the coral triangle and to keep it safe/help it recover?
El Niños and La Nina’s are associated with bleaching-changes sea level (lower) and sudden changes in water temperature. Warmer waters are fine for corals.
This was an amazingly good presentation. Do you know anything about the coral reefs of south Florida and Caribbean? I've seen some stuff claiming the amount of dead coral there is catastrophic, but in today's cultural fetish for catastrophism it's hard to trust the media.
Caribbean reefs are relatively healthy, with many corals recover after 2023. The main problems of the Caribbean reefs are disease, water pollution and the decline of sea urchins, but not bleaching. If you watch the Coral morphologic videos, you will see the hardest corals - Acropora in Florida that resist bleaching thanks to the resistant zooxanthels Durusundium and continued to thrive during the summer of 2023. Life always finds a way. ruclips.net/video/3IdvD-YjVqc/видео.html
Good to see some common sense
Bravery to to say the truth (which sad this is the case).
Is 'coral ivf' effective?
It works, but is a total waste of time - not necessary. There is so much coral spawn, because the reef is healthy, that corals will effectively grow completely naturally on any suitable surface. Scientists are playing around planting areas of coral the size of a few tennis courts. The Reef is as big as Victoria.
octane really?
No, it's the average increase. The problem is long hot periods which correlate with the minor increase in average temperature.
So you're saying it's donaldtrumpdioxide?
Nice cherry picking there Peter. Still getting paid by Gina?
Gina _pays_ him for picking her cherry? Damn, the guy _is_ a rebel.
ROFLMAO
Our coral reefs are dying. It is only partly due to climate change. Any diver knows this very well because you can SEE IT WITH YOUR OWN EYES (as in get out of your house and look for yourself). I am not sure who this guy is or what qualifications he has, but it is scientifically inaccurate to assume that in the span of human timeframes that the coral reef will return to what it was say in the 1960s. At any rate, though, I'm being a downer for the nothing-to-see-here climate change deniers who watch this stuff (I thought that crowd was keeping their mouth shut more nowadays, but I see they won't disappear until the bitter end). So carry on with your climate change denial! I know you need it to face your kids.
GBR is the largest it’s been since records started being kept. They are not “dying” as you intimate.
This is a scientist explaining science. There’s only one denier here. Now I grew up diving on Australian reefs from the 1960s now I dive in the coral triangle which has much warmer waters and I see all the same corals I see in Australia.
