ive read alot of papers on coral reefs adapting to bleaching and i read one on how some of them have acclimatized to heated waters it was super cool it was a recent paper
I just wanted to say thank you so much for "hope spots" like this and your recent video on reducing bycatch. Hope can be easy to lose sight of, and it makes such a difference to be reminded of the ways people are making things a little less bad right now.
I wish we could reduce carbon emissions enough to make these kinds of workarounds unnecessary, but I still think they're really cool! We've already reached a point where temperatures will continue to rise, so we might as well prepare for a certain amount of inevitability.
Carbon emissions have absolutely nothing to do with global temperature rise. You were lied to in order to implement carbon taxes. The global temperature was going to go up anyway. We go through cycles of warming and cooling, and we are still in the warming phase since the end of the ice age. We have more than enough plants on Earth to offset the carbon emissions, even though we've literally lost more than half of the worlds trees in my lifetime (40 years). When the Earth was nothing but magma, without any plants to offset any carbon emissions, the Earth was doing nothing but cooling. If it didn't, we wouldn't have any solid land today. Do you know what would actually happen if we grew so many plants that they sucked up all of that CO2? The Earth would get a lot warmer. If you haven't noticed, rainforests, which are all plants, tend to be very warm climates while deserts, which have hardly any plants, get to below freezing at night, even near the equator. When you have a greenhouse, what actually causes the greenhouse to warm? The sun, right? It isn't so called greenhouse gases causing it. Because in a greenhouse, the plants are taking up almost all of that CO2. They have windows to let air flow through so the plants don't run out of CO2, and to release excess heat. The CO2 isn't causing the excess heat since there would be a lot less of it. By the way, empirical evidence, or proof, is gained by experience, not by education.
Laser specifically. It stands for "laser imaging, detection, and ranging". RADAR originally meant "radio detection and ranging", but that is now an anacronym.
Pumping water from the deep to cool coral close to the surface might accelerate the heating of the oceans by heating water that might have been protected in the deep.
3D printing coral is cool and all, but it kinda feels like putting a band aid on a gunshot wound. What we really need to do is stop destroying the planet in the name of the almighty dollar.
So we’re now looking into putting a bandaid on a problem vs fixing the root cause of the problem? Have we just given up, discovered that we can’t win, or are we just plain stupid?
Well that seems like an terrible idea... Only a small fraction of the coral is surviving and they want to mess with that to? That strikes me as hubris. Especially if they're trying to 'cool' those patches. Those patches likely have heat resistant subspecies. When the corral around them dies, that will allow them to expand. That's evolution/natural selection. If they cool those patches, that may allow the non-heat resistant subspecies to move in and compete with the heat resistant ones, which may have an advantage in cooler temperatures. These heat resistant patches may be expanding 'because' of the warming water. Cooling them would create a selective pressure against the very traits we should be cultivating. The smart move would be to work 'with' evolution and take a limited number of buds from the surviving heat-resistant subspecies help them to spread. I get it, we're sapient, and so we think we're smart. But sapience is only one kind of intelligence. Evolution, using an entire 'world' of biomass as a computational substrate, is going to be able to come up with and test far more ideas than we can. However highly evolved our brains are, they still only make up a tiny fraction of the worlds biomass. And if you treat the pseudorandom nature of evolution as a type of computation, it dwarfs ours. I think it's hubris to step forward so brazenly as if we were born to lead this world. I think humility and caution are the virtues in this circumstance. Both evolution and sapience have strengths and weaknesses. They are both tools. And a smart ape uses the right tool for the right job, or the right 'combination' of tools. Binary thinking is so often foolish thinking. We should be working with evolution, finessing it, not trying to dominate it..
@@BrooksLittletree Really? Well personally I'm open to the possibility I'm wrong. It 'would' be ironic, and hypocritical, to accuse others of hubris while refusing to consider new ideas myself. But being convinced of it would require new information. So, present your argument.
I find it both hopeful and unnerving how many SciShow videos lately have been like "Here's how scientists and engineers have been bandaging the symptoms of climate change".
It's interesting (and sad) how scientific consensus has shifted from trying to lower carbon emissions to creating new technologies capable of mitigating the effects of climate change. It's like everyone agrees that politics will never fix this
What’s sad is that so many of you have fallen for this nonsense. Earth has been much hotter than the cliff edge science keeps whining about. Humans evolved into history at a much higher temperature and corals have lived through the hottest of times.
@@bdawg-qj9bq This shows that you've never taken a single biology course in your life. The environment changing is not a bad thing as life can always find a way and evolve. The issue with modern climate change is just how fast it is. The changes that occurred over the past century alone would have taken the earth many thousands of years to replicate. This is way too fast for most species to evolve to survive better. Don't get me wrong, even with the most extreme climate change, life on earth will absolutely still survive, but it certainly won't be as hospitable to humans, and that's our problem
"As our oceans heat up..." So then why is the guy who insists it's all a hoax getting back into power? Check back in four years and we'll see if the country cares. I do, but then I'm on the losing side.
In general, I am not a big fan of the video. The first „solution“ is technically extremely complicated borderline impossible to do. Same for the 3D-printing. I would definitely not call it „saving coral reefs“
Corals have been around for literally hundreds of millions of years, through many warmer and cooler periods on earth. Why are they suddenly having problems now?
The issue is not change, but change at such an unnaturally accelerated pace that evolution cannot adapt fast enough. And sure, it's likely that even if we did nothing, a few corals would survive the extinction and the evolutionary line would not die out entirely and would eventually recover and rediversify, but it would still be catastrophic and take thousands of years if not millennia
There are dozens of reef building lifeforms that went extinct back than for the same reasons. Salt, heat, cold, acid. Ocean lvl rising and falling. The corals we have now didnt exist as plentiful before the extinction of the dinosaurs. Probably 10mio. Year ago when oceans were warmer diffirent corals lived in the oceans that like warm waters but then ice ages happened. Corals can and will bounce back but it takes a long time
In other eras, climate change happened over thousands or even millions of years. The coral and microorganisms had thousands/millions of generations of time to evolve. This current era of climate change has barely been happening for a century. Also, fossil fuel companies buried the environmental impacts of petroleum and natural gas extraction and emissions back in the 70s. The richest people in the world did not want their investments to lose value. The same people are still alive.
The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS), and that is despite reports of supposed repeated bleaching, despite starfish predation and despite any bad weather. It should be renamed the Greatest Barrier Reef! If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades. GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool - the hottest major water mass on earth. Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
Remember a few years ago when every news source proclaimed that the eminent coral apocalypse was upon us? Whatever happened with that? It's been like 3 or 4 years and the great barrier reef is apparently still kickin. A brief search of news articles brought me to an article about the fact that tourists are regularly destructive towards Australian ecosystems. Makes me wonder if the government has played down direct human roles in Australian environmental degradation.
@Concidineart Everything about that thumbnail is screaming ai. Look at the build plate, the extruder, the lines from the motors shooting up into nowhere, the comically oversized coral that goes beyond the build plate, the senseless buttons. Quit rage baiting
"We're a species who can look at coral reefs from space" is a good perspective to have.
ive read alot of papers on coral reefs adapting to bleaching and i read one on how some of them have acclimatized to heated waters it was super cool it was a recent paper
The Sealife aquarium in Orlando grows coral in their exhibits. They transplant coral back into the wild once it’s large enough.

When coral reefs get cooler upgrades than my living room.
I flooded my living room with cool water and it didn't make me less stressed
@@Vidar_Odinson Did you try turning the breaker off and on?
Mini split. It can heat and cool. Many can cool a lot more efficiently than a whole house unit.
Cyborg coral is pretty sick
Coral reefs: "we're cooked"
Yup, we humans are bad on this planet.

I know what RaDAR is I am assuming a bit but LiDAR is the same thing essentially but they use light?
Yeah it uses lazers!

Am I the only one getting serious science fiction vibes from a living entity that has been manufactured to spy on its living counterpart?
You seen the BBC/PBS _Spy in the Wild_ series?
@GSBarlev I have not.
I’m thinking the same 😂

Bioengineering coral and teraforming Mars. And then we do what we do at sea level.

5:02 ARAGONITE! I have a nice chunk of that from my Rocks Box!! 😂🤍🤍
Already with the lies. The coral reef growth has been setting records.
It's UV from the sun that's killing the reef, UV light has increased in strength, so has infra red

Immature, undeveloped.
Because he is rich and enough people are, depressingly, even dumber than him
I think those corals are just refugia'n to change. 🤷🏼
Sorry, but the first sentence of the video is already incorrect. Oceans are the part of earth warming the slowest. Land regions warm much quicker.

The speed of the changes is unprecedented. When it gets too hot, no more leaves.. and mammals shrink. Algae dies, and the oceans become acidic.
