13:00 - there's face of an intelligent man who has been utterly devastated by the conclusions of his studies. It's hard to bear watching the slow death of everything around us
The Great Barrier Reef has fantastic coral coverage. Over the very short period of around 36 years since people have been taking more notice of it, growth over the the last couple of years has seen an all time high. Coral reefs flourish better in warmer waters. Coral reefs of Scotland don't do so well. Coral reefs towards the equator flourish much better.
I'm really surprised there are so few likes/comments/views of this video.... Like really this is like THE GUY to listen to about the coral reefs. The lack of traffic here is just indicative of how many people know about this issue... too few.

I am a Marine Meteorologist and this is what I know. Up-welling currents from deep in the Coral Sea are pushed up against the coast in north Queensland by trade winds from the south east (for most of the year) to the extent the mean sea level at Cairns is 30 cm (a foot) higher than the mean sea level at Sydney Harbor far in the south. Since water seeks the lowest level this gives rise to the East Coast Current (ECC) which flows south at around 4 knots measured at the flow meter on the monitor buoy off Cape Byron. The effect of this river in the ocean along the east coast of Australia is to continually flush the Great Barrier Reef (GBR) with fresh sea water and nutrients as well as distributing coral polyps during the annual blooming. Run off from the land and any pollution are quickly carried away on the current which can extend up to 100 kms off shore. This process has been happening for millions of years and the ECC determines the extent of the GBR. However, it has been discovered that the El Nino/La Nina Southern Pacific Oscillation can effect trade winds and even reverse them for a time and this will effect the ECC. The effects are still being understood and may contribute to coral bleaching. Current flow on the land side of the ECC can be confounded by a series of eddies moving down the coast inshore which can provide confused seas. These are termporary effects and the GBR soon returns to normal. Overall, the GBR is in good health.
The Peter Ridd court case concerned Bramston reef off Bowen and a photograph taken in 1994 that Terry Hughes from James Cook University has been claiming proves Acropora corals that were alive in 1890 are now all dead - the fringing reef reduced to mudflat.Meanwhile, Peter Ridd from the same university, had photographs taken in 2015 showing live Acropora and the need for quality assurance of Hughes’ claims.
This knowledge and consciousness of what is happening to our coral reefs all around the world, including our island of Vieques’s, off the coast of Puerto Rico, home the natural reserve **Parque La Ceiba de Vieques, is no exception. NOAA has implemented several programs and recruited community involvement to study, replant, control the Stony coral soft tissue disease affecting the coral reefs. We will share this video, and any others you can share to educate, recruit and make our people conscious of coral reefs importance and all they contribute to the balance of the ecosystems we are part of.

As i understand it lab experiment on Carboniferous exoskeleton groups with higher CO2 concentrations leads to improved ability to form said exoskeleton. The temperature is the main basis for bleaching (apart from run off) but is not significantly anthropogenic (only a fraction of average temperatures is attributable to CO2). Glad that these systems can recover and glad that we are entering a period of lowering temperatures (solar minima).
Most of it didn't and many animals wen't extinct. What you are seeing today is the result of evolution beyond the last extintion events....but do you want to wait millions of years to see the earths ecosystems to recover...this is VERY RAPID change within 100s of years not millions...humans will make their own environment unlivable if we keep up the pace we are currently on...it is as if we have a DEATH WISH....an EXTINCTION WISH...I don't want any part in this insanity!
While this is all wonderful and very impressive, the future is already doomed to failure. (It is about as effective as yelling to everyone in the house that the bathtub is overflowing and mopping up the wet floor, while the faucet is still running full blast!) We all agree that the oceans temperature is rising, especially when the planets protective ozone layer has massive holes in it and is rapidly letting in more heat from the sun, because billions of tons of toxic pollution is dumped into the air, when you have Japan dumping over 1.5 MILLION TONS of boiling hot nuclear waste into the ocean (the result of the 2011 tsunami that destroyed their 3 nuclear reactors) and when the population of the planet increases at an alarming rate (consider the population of the planet was 1 billion in 1919, and today it is over 8 billion in 2019. At that rate, the population of the planet will be over 16 billion in 50 years) there is no way the population of this planet can afford to stop the industrial giants from polluting the planet when so many people are desperate to find work to feed themselves and survive at any cost. Man is a cancer eating this planet alive, and there is no way to stop the lethal effect man has on the environment, from greedy and corrupt corporations using the oceans and the air, as a toilet for their toxic industrial waste. (Sad to say, but it is simply too little, too late folks.)
You cant state that coral is dying more then ever, just by counting or observing dead coral. If i would count the number of dead people in my home city, i would come to the conclusion that humans-species is terminal, since more people are dying every year. If i would analyse increase of cementairys,my conclusions would fit this projective since they got bigger . BUt we all know that this is BS. You must count dead coral relative to dead coral of previous years relative to still living coral in those years. higher water temperature seems not effect coral since the temperature is different throughout the whole east coast of Australia, also it seems that the hotter the sea, the more coral. and thus in "bad"times,more dead coral. Also in his estemated coral loss picture you can see that there is no correlation between dead coral and sea temprature,you can see a relation that more see coral is dead the closer to the University, So conclusion, more James Cook University causes dead barrier reef! In the middle east,where sea temperature is much higher there is no huge bleaching event. In his talk hes connecting global climate change with the dying of the reef, however he never explains WHY temperatures increase would cause bleaching. the picture in the beginning of his lecture of good coral is taking way closer to the sea, also change in seasons explain alot. I can show you a picture of my back garden in Winter,and Summer and claim that summer is way better for the plants and flowers and that climate change is a good thing! This talk proves NOTHING!
Temperature increase causes coral bleaching because when the coral becomes stressed (from unusually high temperatures) the algae that live in the tissue of the coral is expelled, depriving the coral of its colour and vital nutrients. The coral then starves as a result
well in the end you say to keep this treasure , i would say to stay alive !! as without coral ocean life will die and without ocean not life on the planet , so hello just speak it up , !
Exactly and well said ...it was another Australian coral scientist Charlie Veron that said exactly what you have said...if the coral reefs die then the oceans will die because they provide 25% of the total ocean biodiversity and provide nursery zones for many species beyond that...if the oceans die we surely will die and much of life on the planet will die...at least for a while until we die off and stop killing the planet...then the planet will recover and in a few million years the place will be magnificent again..
if you think the solutions for coral reef to survive is reducing emission all coral reef is going to go extinct that is not a solution its a big problem. Changing emission takes time can't change in a day.
Well then I guess we won't have coral reefs then ....this is the problem.....we can save the coral reefs and the earth if we CHOOSE to....it is not a matter of possible but of choice and we will all have to live with THAT
Unfortunately nothing concrete about how global warming affects the corals; the sea temperature is rising I suppose? And with how many degrees, and what is the desired temperature around the corals?
The desired temperature is what they have evolved. In nature, temperature variations to large areas of sea are very slow, and coral have time to adapt, whereas with human caused climate change it's getting warmer quicker.
The rising sea levels also reduce the sunlighrisk getting to the reef, whigh the algae on the corals requires. It also adds to the amount of storms which can kill coral.
Additionally to the other replies the increases in CO2 into the atmosphere make there way into the oceans lowering their Ph(acidic/alkaline levels) lower ph = more acidic. This makes it much more difficult for hard corals and other organisms to secrete their skeleton of calcium carbonate. The lower Ph levels also effect coral settlement.
@@daebyun and what are the ph leves of the australian east coast at this moment compared to say 20 years ago? And is there an actual test in a controlled environment that vindicates an increase of coral death relative to the supposed ph change that occurred?
I am working as a Teacher. I will influence my students and their families 👪to be part of solution to Coral bleaching..decline. let's find possible window of opportunities instead just talk. We can. We have only one Earth 🌎❤ we have to save
What? That is your level of comment? This man has devoted his life to researching the magnificent reefs of this earth most especially the Great Barrier Reef located in Australia (add so you might be able to figure that out) and all you have to say is "Poo". That is totally pathetic and I don't understand why you even bother to add your comment...you probably made it though a minute of the video and then bailed.

This speech is so important I will let all my family member to watch this😍

4 years later and we've only regressed since then.
Wow this video si really good every one should see it
I wonder if you could divert some of the cold deeper water to the corals to cool them during a heat wave?

Choose... " COAL" or CoRaL. Let's contribute to save coral

It's serious issue to think million times before lead lavish life. Coral devastating promoting industry goods should be reduced
Please I would love a chat about some fundraising I want to do for your research and the ARC .

How did coral survive the jurassic age. Wondering
Most of it didn't and many animals wen't extinct.

Very impressive information
I work what I can to save coral by changing lifestyles instead blaming just polluting industries
