Why don't we start casting Lava to build homes Lava rock homes use to be a thing.
Hawaii has a active and relatively calm volcano that has Lava flows.
Thoghts.
Please indicate when a video is a compilation, thanks
@babysquirrels bro, the guy just has long hair. Don't be dumb
Why is CO2 making volcanoes?
False thumbnail
CO2 is definitely odd stuff. Think the weirdest thing I've run into was when I was working as a mud logger my boss told me about an accident on a rig back in the 70's that he was working on. From what they could figure out they ran into an old lava tube that was totally filled with compressed liquid CO2. Shot out the entire drill string, blew out the blowout preventer, and sprayed liquid CO2 all over for a couple hours. I forget exactly where it was, but it was in the southwest desert in summer, and he said that a frozen rig sparkling with ice crystals in the ninety degree sunny day was the most surreal experience of his life. Man, I wish I could have seen that.
Did anyone die?
Thank you for sharing your imagery. i have a good imagination and it looks spectacular !:-) 🙏
Sounds like a story to me.. at 1 atmosphere of pressure there can't be liquid CO2. In order to do that you are talking about Temps of -78⁰C or at least 5atm of pressure and the porosity of a lava tube would not contain that kind of pressure. It's a cool story even if it's fabricated
@@dhirmer Probably a mixture of CO2 and water, which would lower the vapor pressure and be more realistic to find in the ground. Plus he may not have actually hit the lava tube, just removed enough overburden that the pressurized mixture could finish it's own excavation
@@dhirmer Ever wondered how a fire extinguisher gets cold when used? If gases expand they drop in temperature. The reason being that the total heat energy remains the same while being spread out, causing the tempature to drop. So if the gas gets cold enough, it could become a liquid.
(Note that heat energy and tempature are not the exact same thing)
"You venture into the darkness, and you never know what you might find. Glowworms, crystals, millions of sleeping bats, a horcrux, Grendel's mom." Nicely played.
Geez is that a Beowulf reference?
MacKenly, that is definitely a Beowulf reference.
As a collector of different versions, tellings, editions, etc of 'Beowulf' : Especially appreciated.
They forgot Grendel himself!
@@fionagibson7529 You don't go find Grendel.
Grendel comes and finds you.
These vids always reminds me of how much Hank has changed over the years. And how this channel itself has changed, for the better, of course! ☺️
Hank used to have a very persistent tic to bring up his hand to his glasses, he was fidgety. You'd think that with the progress he's made in SciShow, he woulda completely lost those, but he's actively suppressing. You can see it on his tiktok videos/personal channel, he still got them. Super interesting stuff!
Thank you. Appreciate the complexity and intricacy of our earth and your coverage.
"... to be honest, they're a bunch of creepy looking weirdos, but I guess living in total isolation in darkness for millions of years will do that to you..."
ROFL
Love you guys!
"Explosive De-gassing", yes, I'm familiar with that effect, it causes me much giggling... :P
Can we get a slow mo vid of Michael shaking out his hair like a super model? I came for the science but the eye candy is a bonus 😂
I thought it was just me that couldn't focus because of that gorgeous mane.
This is what people mean when they say "The lake is going to turn over soon" -alluding to the processes that cause the CO2 on the bottom to bubble up to the top, causing the silt to rise and spread nutrients through the lake
Most often the mixing of the strata in lakes (overturns) are caused by changes in temperature, driven by seasonable temperature variation, not CO2 or other gases. The lakes mentioned in the video are extremely rare.
I love that you guys are back to this set up. It brings me comfort. Also, Grendel's mom! Lmao
I miss young hank always cracking jokes about the video subjects.
the Beowulf reference caught me so off guard and shot me into 7th grade english class oh my god i haven't thought about that book since i put it down
Mike, still rockin those righteous locks, lookin good🤟
When lightning strikes it actually helps clean pollutants in the air so assuming everything wants to be balanced. I would say this is earths attempt to balance out that acidity
7i my baby 🍼
8:01... I find this fastening. I would like to know more about the process of harvesting methane from the water and using it as fuel... I watched the entire video. But, I have to say. Around 22:57, my brain began to ache. I enjoyed this one. Thanks.
Probably began to ache because they contradicted themselves so much.
Fascinating*
2:38, I once knew someone who had the same problem
Very interesting video! Love this channel and the videos 😊👏
9:31 I- was that a Beowulf reference??? Or was it a reference to something else inspired by it or something?
My 6yo thanks you so much for the details on the explosive degassing.
0:41 Fannette Island. I have stood in that spot. It's on a hiking trail. Lake Tahoe is such a nice area!
Loved his white and gold shirt 🤣
Came to say this same thing, saw someone beat me to it by almost a year; ain't even mad, just glad to see someone else with the same sense of humor! 😂
*High five*!
Thank you. Your efforts are highly appreciated.
Looking for a lava lake? Dont forget to bring a fire resistance potion with you...and netherite armor
There are "about 5" active lava lakes in the world......ABOUT 5??
Sure, when volcanoes do it, they call it Explosive Degassing. But when I do it....
Very cool to use Lake Tahoe as your “beautiful lake” and emerald bay at that!
My favorite part of Tahoe! 💚
Enjoyed this!
I feel like I should compliment you on the beautiful hair. It’s gorgeous
My favorite part of CO2 lakes.. industry is proposing putting our extra CO2 on the ocean floor where it'll become liquid.. and one quake away from disaster.
His hair is phenomenal.
Is there a published experiment with different greenhouses with different gases demonstrating the measurable temperature differences they can have? I feel like this would settle the debate.
There are such studies, they were generally done within a few decades of 1900. You'd be well advised to look them up if you're interested, but in general you get two small glass enclosures, label which is which, take some initial measurements with normal air in both, designate one to be the reference object, change the atmosphere of the other at night, and record measurements of both internal & external weather (internal weather will usually just be gas composition, temperature, and maybe pressure). If you had clouds, drafts, etc., then you might occasionally need to duplicate an experiment.
Mount Erebus is named after the HMS Erebus, later to disappear (till 2014) in the Franklin expedition.
I’ve never been so mad to finally totally understand pH. I HAVE A GEOLOGY DEGREE AND NO ONE TAUGHT US THAT. That makes it SO much easier to understand my Organic Geochemistry class from 5 years ago. 😤
OMG Phil Oakey”s kid brother!
Harsh, but fair.✌️
Do plants process methane too or just CO2?
Just CO2.
1:48
So like a fountain? I’m sure that would be a better analogy
Two distinct individuals, who don't even resemble each other - and yet, they have almost exactly the same voice. How does this happen?
How many people think that chemosynyhsis is the most likely form of life in the universe. It's easy not to notice species buriedbunder crust. What if photosynthesis is an anomaly of earth?
15:50 So why not put a giant outdoor Marx generator tuned for the same impulse profile as natural lightning on a ship and go for a trip? That would be far better than a beaker of salt water and a 100kV HV power supply bought from eBay without the 9v battery. Still not quite as good as the real thing, but 200m- sparks are better than 2cm ones.
movile cave is (hopefully) the closest thing we have irl to the mystery flesh pit. idk why that was my first thought but i stand by it
1:17 Noone talking about Mount Terror there? Huh.
It always bugs me when the first note of the intro music comes in late and sounds cut off, at least it sounds like it to me.
Giant lava lamp..nice mother nature
Maybe he's born with it. Maybe it's ... Michael Aranda.
I love hank's white and yellow shirt
“Outside of Minecraft”😭😭
Not sure the title makes sense. Isnt it meant to be be 'the weirdest places CO2 IS made'
They think CO2 is a very powerful molecule.
In reality is heat and magma shaped Mt. Erebus, its main crater and lava lakes; The Movile Caves were shaped by water and most of the other things were shaped by other totally unrelated environmental factors with CO2 being a completely inconsequential feature that shows up around all of them.
The CO2 made these places
How did scientists measure the depth of the lake ?
I think they used a Ground Penetrating Radar, or GPR. It's just a guess, but they do use those machines to map out underground caves and determine how much liquid, usually water, is in the area. So, it wouldn't surprise me if they did use it! Hope this helps!
That beaker co2 experiment seems like bad methodology. Surely the co2 bubbles would act as nucleation points for the simulated lightning, but ocean acidification doesn't cause co2 bubbles to rise from the bottom(except maybe a local event dissolving something somehow)
I can't remember if I checked out the paper when they originally posted that video or if it was pay-walled. Regardless I don't think the beakers were actively bubbling when they tried running a current through them in the actual experiment.
@@VariantAEC that's reassuring. I would expect they knew what they were doing, but the animation sure makes it out like they just started bubbling it with the power still on. Still, I'm not sure that's a good analogy to the straight diffusion of atmospheric CO2, I mean even if it got much worse, the seas are still going to be flat(like the earth trollolol) not carbonated like a soda.
Thanks! 🙏
Considering the salinity of oceanic water, I'd doubt that carbonic acid has much of a effect at all. Not saying it's benevolent, but acidification is a long stretch to link to lightning intensity. The destruction of coral will be much more significant. Just my opinion, though
I have had my share of explosive degassing episodes after a trip to Taco Bell.
I think I did see that coming, it was your thumbnail after all.
Nice
i just realized how well written these vids are. the imagery helps so much to visualize and intellectualize what is occurring. the whole episode is written very logically and is easy to follow. i even get some of the physics vids :)
and, of course, delivery is everything when it comes to understanding also. every one of you is great at voicing these lectures like actors need to do.
i don’t know why i haven’t thought of this before. Oscars to everyone. 😋😊😻🌷🪻🌱
I love your productions! Your "water scorpion" is actually a Giant water bug, a true bug. Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs.
Hi @SciShow
Why does the description speak to joining Michael Aranda.... when Hank Green covers the majority of the content... and Michael Aranda puts in a few transitions, and ancient content where his hair is like 6" Shorter?
Outside of Minecraft got me rolling😂
Red sprites have bee observed more often above storms over the ocean.
red sprites??
@@88smileandnod go look at Pecos Hank's channel
Earth needs more CO2 not less.
No it doesn't.
Question is can we harvest the energy from the lava lake with a thermal electric generator
We already did, Yay!!!
That's what Geothermal Power Plants are for. There is some in Norway, Indonesia and several other countries with volcanoes. Its reliable, relatively cheap, might last a long time (some volcanoes remains dormant/no eruptions for centuries or more).
If we can find metals that
a can survive that constant heat and wear an tear, and b if we can find ways to prevent the internals from melting
@@classydemongaming847 You don't need to have a metal that can survive the lava, just place the pipe near the depth where water could boil(100°C, most metal alloys can handle 5-20 times more than that, and with the water cooling it, it will almost last forever, minus the corrosive damage) and use the steam to move a generator/steam engine.
@@drextrey I just liked the idea there because it's Antarctica. Thermoelectric generators work better with greater differences in temperature
@@samuelruiz7377 True, but under current technology, Peltier Plate are very inefficient , steam engine do much better for less cost.
And even if they want to build generator using peltier plate or something similar, it won't make sense to let the plate directly in contact with the lava or any direct heat since it would destroy those equipment easily, the most sensible way is to use water or similar heat transfer method to provide the heat(and cold) for the peltier plate in a controllable manner.
What does more intense mean? More current, voltage, charge, frequency...?
Also consider that it might refer to intensity of light. (Just adding to the list)
Totally unrelated but I love micheal's hair, it looks really healthy and beautiful thrown over his shoulder.
I also have explosive de-gassing coming from deep within my magma chamber 😂
😂
explosive degassing. whoot.
I sure love hank
Play this at 0.5x speed then your host is absolutely drunker than piss! Your welcome
8:08
I’m telling you know that idea will be met with a lot of xenophobia and may be seen as trying to take control.
0:42 I'd recognize lake tahoe from any angle
If the moss can be that effective we might actually have to be careful about how much we use then... we're talking about something that started a whole entire cycle of global glaciations simultaneously. All glaciers have that upper age limit, as he said it was an entire greenhouse earth before that with tropical like poles.
Also I hope opening that cave up won't cause atmospheric differences that would endanger that ecosystem. I understand that at least co² is slightly heavier than average air so that probably will stay mostly put, but hydrogen, at least elemental hydrogen, isn't... maybe they need to put an ecological preserving airlock on that...
8:00 wait, Methane can be used to generate electricity!? Why aren’t we doing that with all the methane that factory farming is producing?
Economics. Collecting the Methane turned out to require not insignificant amounts of infrastructure. Given that factory farming is about cutting every cost possible (and getting subsidies to cover the rest) most don't even try.
There are farms that do use this, thought. But the ones I've read about has been smaller ones that has gotten some kind of government subsidy to to it as an experiment/demonstrator. Effective greenhouse gas taxes would probably make it a lot more attractive.
The amount of life we have found that can exist without light or oxygen is astounding. Are their theories as to whether this sort of environment could support larger life and brains large enough to to support intelligence?
If i swam to the bottom would i find a bubble i could potentially step inside of?? I have to know
What's the probability that someone could modify Azolla to survive in saltwater? If they could, and drop it way out in the ocean where it would be more calm (like maybe the garbage patch?) And just let it grow, would that help with our current CO2 problem?
carbon dioxide is a good thing. we need more of it
Lava lakes are a little less serene 🤦♀️🔥😆
The extra long antenna are so they don't bump their heads walking through doors.
Did anyone notice how he talked weird when he talked about the lakes with the lymnic eruptions?
Yeah, he seemed to talk lightly about a lot of people dying.
@@ttun100 I noticed that too. I know the emphasis of the video is the scientific explanation behind the phenomenon but the thought of over a thousand people asphyxiating made me pause for a moment in sadness. I've just spent some time looking at photos of the aftermath of the Lake Nyos disaster on Getty Images and reading survivors accounts, it was truly a massive tragedy. I know that was an older video and Hank's presentation style was different/more exuberant but it does show how sentence intonation makes a big difference in how you convey information.
What about MSG though? That's saltier than salt and it's already used as an additive in a lot of foods.
we better get some more Azola for the planets sake then
Isn't a "crisis" something that is an immediate and pressing danger as opposed to something that plays out across 100 years or more? Science!
I have that too sometimes 3:40
Linode rhymes with commode almost
This is good news for electric eels
Just check out the weather satellite that has been taking the earth's temp since 1979 and see if you think there is really that much to worry about . We do need to clean up our act better , but plastic is a worse problem than climate .
And is needed for plants to live and grow..
lava submarine when?
Maybe acidity is why the deepsea snails have iron in the shell.
What would happen if people stopped using vehicles?
"explosive degassing" sounds like something you should see a doctor about
Are we planning on studying the gas emissions on our expedition to Uranus?
Sorry to ruin your fun, but yes.
Did anyone catch the fact that Scishow mentioned cold water retains CO2 better? That is true.
Now in this very same compilation they mentioned CO2 will be trapped in the oceans... but how would that work if CO2 keeps the water at the surface too warm for CO2 to dissolve into it in the first place?
I eagerly await answers.
Additionally that fern they were talking about didn't eat up significant amounts of CO2 and instead it was the shift in the land-masses that drove monumental changes in the Earth's climate allowing water to reach the poles and cool off radically in the winter months to the point where parts of it permanently it freeze creating a constantly cool mass of ocean water. But I mean I am no expert... those are just my thoughts.
Interesting it's probably in different situations
I take that back. I think it comes from rainwater.
@@AndrewTBP
That is generally another way CO2 precipitates out of the oceans also being incorporated into the shells of mollusks. That is something Sci Show has almost claimed could be the demise of shellfish...
I've already tried to explain that the most acidic sea water plays host to many crustaceans and the like. Expectedly the most acidic sea water is at the poles where it is cold and CO2 can remain dissolved in solution... because it is cold.
Ocean water isn’t saturated with CO2. Hence even with slightly elevated temperature there is more CO2 to be absorbed. Water a few feet down is much cooler than the surface and hence can absorb for CO2. There’s your answer.
@@AndrewTBP I was initially thinking this, that most of it ended up there as marine snow or critter shells.
“Lava Lakes” sounds like a location in Fortnite
if lightening gets stronger will that regenerate ozone?
As a canadian, I really don't see why y'all fret so much about the climate warming up. I imagine lots of people will find Canada a wonderful place to visit jungles and tropical fruit orchards, and for once the inhabitants of future Cuba will visit The Northern Territories for the wonderful beaches and a respite from THE SCORCHING SUN ...
Next year I will sell my snow-blower and buy a HUMMER, the greatest ice-age-be'gonner in history. Wroom Wroom
All statements that begin with "as a Canadian" will undoubtedly be epic.
Yeah, I hope your immigration system is ready for a couple of hundred million desperate people from south/middle America needing somewhere to live...
As soon as he said supercharged lightning I heard a turbocharged car pass by, weird.
What does a Lava lake have in common with my dog?
Idk, what does a lava lake have in common with your dog?
Why don't we cast Lava in blocks and use it to build 🤔.
Lava rock homes use to be a thing.
Hawaii has a active volcano thars relatively calm.
Thoghts 🤔.
because real life isnt minecraft..
I think the main problem with that is that there aren't really enough volcanoes that would work for that to meet the demand of building structures
Beyond the fact that it would be so expensive it would be prohibitive, it is also nearly impossibly to get a steady supply of lava that is easily accessible. For example, only 5 consistent sights on earth where there is a lake of the stuff.
The science stories are linked to the human body already.
Insert Explosive Degassing joke here.
