- Oceans are acidifying at a rate faster than any time in the last 300 million years. This year, we've seen the most drastic and damaging coral bleaching event in recent history - and it's attributable to warmer, more acidic oceans. It's time to take bigger steps to reduce our impact on the ocean's ability to restore itself.

Anyone else here for schoolwork? Or is it just me?
Yup lol
same lmaoo
Me
Unfortunately yes
I’m here
I have a question: If the Oceans are indeed warming, then doesn't it stand to reason that some areas, which had previously been just a bit too cold for reefs to form, will become hospitable for reefs? I'm not trying to make light of what's happening in reefs, it's just my sense of logic and curiosity forces me to ask.
Thats actually an interesting question! All I know is that there are other factors than temperature that play a huge role in these ecosystems, for example the amount of dissolved nutrients in the water, the presence of topografic structures on which the reef can form itself, the amount of light and type of ocean circulation and currents. Those factors can be limiting. Tropical reefs need clear water with few nutriënts and need light for there symbionts to do fotosynthesis.
@@meestorn2065 Hello Mees Torn,
Thank you for the reply. You make good points about the necessary ingredients necessary beyond temperature. That said, I'm optimistic the right recipe will continue to exist as long as there are zones with the right temperature and different types of pollution don't ruin everything.
What if the were way off with their predictions. They said by 2013 the poles would be ice free
🙏🙏🙏for the all coral reefs
Omg, when I went snorkelling at the great barrier it was like dead
your people did this, now you must pay

Anyone who dives the GBR knows most of the time the temps are 75-78, and I have never seen more than 82 degrees anywhere in the Coral Sea GBR area even closer to the equator in Indonesia.
Why are you using fahrenheit ? Talk in Celcius that is used by the international scientic community.
It was 86 degree fahrenheit

OMG. Such a big impact.
Ok, but the advertisement I watched before this video was actually super cool. Go, Katie Sowers, you’re badass.

Filter feeders, Nature’s clean up crew, are rapidly decreasing. Mollusks, corals, sea sponges ect. As a result pollution levels will rise much quicker till it reaches a point where the environment becomes no longer inhabitable.
A snowball effect.
Civilizations do not decline gradually but disintegrate.
There has been three major bleaching events on the Great Barrier Reef (1998, 2002, and 2016).
Bleached coral are normally just nutrient deficient, but the bleached coral surveyed were dead due to the severity of the high temperatures.
In 2016, severe coral bleaching has been reported in the Pacific Ocean, in the Ocean, and in the Caribbean.
In a year, severe heat stress has caused negative impacts such as changes in marine species distribution, storm surges intensification, glaciers melts, sea level rises causing human displacement.
Thus, countries like France have been adopting renewable energy resources to reduce the emission of green house gases to fight against global warming and strengthen the oceans.
It's so sad to know that these coral are dying and on an individual scale, apart from spreading awareness and using more sustainable products, there isn't much we can do. As a planet we really need to invest in renewable energy resources. Imagine every coral in the world was dead, all brown and dark and murky, unlike their usual bright colours. Now that would be a sad world to live in!
Coral bleaching is a natural process
@@wandameadows5736 No
i think the culprit sad to say is we humans..well the people who "dont" think nature will grow back itself..it will eventually will happen..if we make solutions to it.
Turns out this is completely false. New studies confirm the highest coral cover on the reef EVER, in the 36 years records have been kept never before has the coral overage been so great.
Agricultural runoff, sunscreens, and natural predators like crown of thorns sea stars are responsible for local portions of reefs experiencing coral bleaching. Temperatures remain 78-82F. Reefs survive at low tide exposed to the air with temperatures hovering around 90F.
Each video that claims water temps have killed portions of any reef must specify the exact location using latitudes and longitudes.
2023.... you should see the records broken today
They were also caught lying about temperatures
Coral are not endangered of extinction. Once the sixth great mass extinction is over the few coral specials that survived will evolve into new forms as they take on new environments and whatever else survived the mass extinction
Seems correct in today's scenario (deteriorating cause above). Coral bleaching a give challenge.
Lowering O2 levels and effecting sea animal health.
At least someone is paying heed to it good coverage.
Well that video switched from utter despair to compounding assurance and belief that the Paris Agreement will resolve all environmental issues. I think I'll just sit back with a beer in hand, knowing now government across the globe have everything under control. What a relief :)
If you want a real good laugh, actually read the Paris Agreement. Some countries simply sent a single piece of paper saying "We recognize there is a climate."
J P sounds like we’re in a good place
Most of us are totally not here for a lesson.
2019 anyone lmao hey
No 2020

@@claireheadspeath9873 How do I travel to that time wit you?
Ocean acidification is caused by Agricultural run off that has caused explosive growths in the crown of thorns starfish. these predatory starfish consume the coral reefs as it dissolves them away. warming waters due to increased sun activity (solar flares) and trapping of heat due to water vapor and C02 emissions have also contributed to the shrinking populations of fish that prefer cooler waters.
Agricultural run off ??? More fertilizer comes out of river systems that dont have farming on em but rainforestry.
Greenpeace boat loading deisal on board had deisal spillage into river....didnt hit the news did it.
The Paris agreement is not legally binding.
The Paris Agreement was complete garbage. Read it! Countries like China actually made a promise stating "We will continue to increase CO2 emissions until 2030" with NO PROMISE to start decreasing after 2030. Germany made a bold, BULLCRAPPY promise they didn't keep. They actually increased their emissions. The USA has pulled out of the agreement, and the USA actually saw a decrease in emissions during the 1st year of Trump.
wow

We have to add shade from space to the poles
Coral bleaching is a characteristic which the creature has evolved from an evolutionary perspective. Essentially, the coral has learned over thousands of generations how to respond to changes in temperature. Wait a minute! I thought that climate change was a new thing. How on earth would it have developed this response. Uhggg! My cognitive dissonance is returning.
nice music
thoes are a lot of bleached corals, wow

Coral reefs have been in the sea for more than 40,000,000 million years living sometimes in water a lot warmer than the warm seas of today. All corals live in warm water and the tropics, that's why you don't get coral at the poles. Plants and animals have always lived and died since the world began they call it natures way of overall survival. The first living things on earth during the volcanic era when the world was unstable and full of gas and fumes Co2 carbon were "plants" there was no other life.
There are a few things you say that are not true. Tropical corals live in warm water, but cold water corals do occur near the poles, in deep and cold water. They are heterotrophic and do not have symbionts that use sunlight to make food. You say the first living thing on earth where plants, thats also not true. Bacteria and archaea where dominant in the first stage of earths life. Because of the oxygen produced by cyanobacteria, earths atmosphere became more suitable for life on land.

Paper or should i say papal
Dapat hindi natin sirain ang corals
Fukushima Dai'ichi: it is an extinction level event - very sad - with whales, dolphins, birds, fish like salmon - all being decimated along the West coast of USA and Canada - the die-off temporally correlates with events at Fukushima Dai'ichi. The die-off is hardly mysterious - it is very clear. There has been the biggest media coverup of the accident in history - Japanese political and industry leaders are in denial - hoping that forgetting about the accident will make the accident disappear - such attitude is sheer madness and delusional.
so many nice words.. so little effort and interest put into it...
catalina 77 for the all coral reef i am sad.

Really. THIS WAS MADE IN 2016. Just me crying over the Earth dying. Nobody even cares anymore. Why? Why.. We need to save the Earth. Please help and spread the message of saving the Earth. I honestly don't know what to do anymore. This is disappointing and we care too much about our high needs. Search up the song Dear, 2045. That should help you realize what is really happening...I love the Earth and all I see is trash everywhere. I think the Earth is dead, from our damage. Barley anyone is helping us...this started in 1985.
It’s just sad man...I keep hearing my friends saying “oh the earth isn’t dying people are saying that just to scare people” and that ticked me off really
@@Zi_on133 Because it's not dying, deal with your delusion and misplaced anger.
Lonelyy shorties... you need psychological help.
The lies started in 1985, the fact is we are doing better now than at almost any other period.
@@GoA7250 So you don't care about the planet? About it dying? I see trash on the highway everyday, I guess a bunch of trash means our planet is doing so much better than It was back then with heaps of trash.
@@maizie.roblox3025 not dying ifiot.
could fukoshima have contributed to this
Ray Barker possibly, but the currents tend to pull more towards the west. Just a wild guess on my part.
was happening long before. Ocean acidification is caused by more carbon in the oceans from my understanding.
Ray Barker yep

Blame it on the French for testing their Nukes in the Ocean right next to our shores!!

This is bad
Coral don't live forever. Among myths promoted. Polyps have a life cycle, while colonies may die in some areas & migrate they become established & reinvigorated in another. Beside that truth, coral reef & colonies have perpetuated over many years of climate variation beside catastrophic meteorologic events & tectonic changes. Other paramount factors are obscured especially adverse direct effects from the coastal & littoral activities imposing physical changes, eradicating ecosystems, & emit toxic pollution. Even exploitation, interference, disinformation, misunderstanding, hubris, dubious conservation & mismanagement impose problems. Coral are diverse, regional & exist in scale not so much massively global, colonies have always only become established where possible. Frankly, much effort needs happen toward promoting transparency & honesty along with overcoming egregious corruption, kleptocracy, & socio-economic disparity prevalent in the world.
