They are scientists, they knew where that big chunk of ice fell from, " looks like it came from up there " brilliant.
They also have extensive knowledge on study grants and thesis projects that folks like YOU, don't know where to begin with, cowboy.
@@discojelly well actually, you can probably learn everything thing they been thought on TH-cam
That’s why they get paid the mediocre bucks!
@@discojelly Did you know they don't use facts found by extensive testing the way science was supposed to ? Now a days science is mostly based on opinions because of their agenda ! Ever notice they never offer any proof of claim ? They never do and wont ! And people blindly take their word for everything they say now ! With just a little bit of research , you will find out we are all being lied to ! All you gotta do is look for yourself !

I remember visiting a cave like this but it was in New Mexico. Before it became part of a nation park it was used like a refrigerator by the natives
Same.
Carlsbad caverns
Not Carlsbad but in a lava flow on way to Albuquerque from Phoenix.Was hardly any structures beside a parking lot and a park ranger. A wooden walkway out into the razor sharp lava field. Middle of August, hotter than 3 kinds of hell! Then a staircase going down into a lava tube. As you decended you could feel very cold air moving up your body as you continued downstairs. The ice cave had been used for cold storage by people way way back in time. It was Amazing
@@mikeashcraft4354 Our middle school used to take all 8th graders to that ice cave and a cave that I believe was east of grants. Really great memories made there.
my co worker was just telling me about it yesterday... cant remember the name ill ask him
Bandera Ice Cave
Very cool place
Look at the perpetual ice cave near Grants, NM. In volcano a vent tube, ice was harvested in late 1800s and early 1900s, open to the public. Growing ice all year long

Dreamlike and beautiful!! To immerse yourself in Nature must be thrilling beyond words..
I first thought, hey, I could make a trip to this cave by myself. Then seeing them crawl into dark holes - I think not. I'm good.
there is also a gate
@@acel2413 he doesn't care. He heard that but pretends he didn't.
@@JM-yx1lmagreed. Guess he’s missing the whole point. The earth is very sick and it’s because of us and no telling what will happen to us.
There could be frozen
Virus stuff too!!
Good thing they lock
the cage door! Let's
stay out!
@@lotusflo12 I don't think the Earth is sick. It is just going through natural cycles of climatic change. I'm sure the humans who lived during the various ice ages would have been huge fans of global warming.
Where the 'dying Earth" idea comes from is because these natural cycles can spell bad news for human life. But the Earth is doing just fine because it has no obligation to keep itself habitable for us. Humans haven't even been here that long when you look at the entire history of life on Earth. I think there is a clock metaphor for life on this planet where the very first human ancestors only popped up in the last 1 second or so.
Pretty cool! I'm always happy to explore old gold mines here in Southern California, but this would be a totally different experience!
on video yes but risky in person .
@@Q_QQ_Q risky is what makes it more special 🙂 I have few videos on my channel, check them out.
Where at do you explore? There's some old silver mines in Calico that my friends and I like to explore. If you haven't yet you should definitely check them out!
@@jacobmcguire1051 I haven't been up there yet, I'm mostly at Sam Gabriel Mountains. Angeles National Forest etc, there's a lot here 🙂
@@MichalOlender you ever find anything cool?
That's interesting information about the earth, because it says: that past 10,000 years ago; this planet was much warmer environment, followed by an ice age. And that region had been warmer for a long period for that stalagmites too form, as far back as 400,000 years ago.
So it can be said that if gets warm enough to cause the ice to melt , the earth is going too trigger a iceage event right after it.
100% correct
There has been, SEVERAL
ICE AGE PERIODS.

Some humans servived, by
going undergroud, like in
Africa. And, other places.
Then, we start all over
again.
Maybe, by 2080 , we will
deal with the Earth full

Then, by 2120, we get to go
underground again.

I'm a little DUMB please
explain
I used to go caving in WV a lot while in high school.....back in the 1970's. There was one particular cave that had a lot of that stuff the guy on the vid said looked like Toffee.......we called it "Bacon" because it has a bacon like appearance when you shine a light through it......light and dark areas. Going "real" caving is fantastic vs a tourist cave. I've gone in caves where the entrance is an 80' pit. Another cave had a huge "big room" that the military supposedly used during WWII to story equipment and materials. No ice caves though. Temps would stabilize at around 50 degrees year around. We did have to worry about hypothermia though, especially in very wet caves.
Back in the 1970's we used carbide lamps to light our way through the caves. Add water to the carbide rock nuggets and it turns to acetylene gas (or some type of flammable gas) that you light up. Man, those were fun days. I even attended a "caving camp" one summer where all we did for two weeks was go caving......and also did some climbing. I lived around DC in NoVa but really enjoyed camping, hiking, caving and climbing in WV in HS and college.
Why don’t you still cave now ?
@@basstion4146 Cause I'm old. fat and lazy :)
That was fun for you.
When we were young,
We went to.small canyons.
to hunt for wild rabbits.
We would work as a team, and flush them out to the front of us.
We were very good shooters because, we usrd to go to a
frozen lake on a windy day.
We would throw empty beer
cans out on the lake. The
wind would move them
very fast! We would shoot
the cans. We got good!!!!!
I used to own a log cabin in Slanesville WV. There is a mountain there called Ice Mountain and the mountain's interior stays frozen all year. There is a small opening you can look into and see the ice in the middle of July or August. Settlers and Indians used to use it to store food in.
@@christschool We used to camp over near Franklin, WV and did a lot of the main caves in that area. Unfortunately, a lot of those cave are closed or limited these days. land owners don't want issues with cavers plus there is white noise syndrome which involves preservation for bat colonies.
If cave formations were not protected by law, the formations could be cored and possibly be dated using isotopes included in the individual layers deposited annually. Sequences of Volcanic eruptions have specific signatures.
Good luck getting coring equipment into a cave lmfao
People I mean thugs would sneak in and draw graffiti on them.
@@A_Degenerate_with_Glasses A camera with security nearby and a 10yr prison sentence (or a harsher penalty) for anyone who desecrates the site would put an end to that rather quickly.
@@kingdomcome1617 no it wouldn't
I have a question for all the human induced global warming nuts out there. Ready? Here we go….
What caused the climate to change, ending the ice age, when there were no significant humans inhabiting the earth? Maybe mammoth farts heated everything up.
Love to hear your wacko responses. Maybe AOC has the answer.
I like it when it’s warm enough to feed the 7+ billion people on earth. Imagine the jam we would be in if it suddenly cooled from a large volcanic eruption or the dust put in the atmosphere from an asteroid.
I couldn't agree more
It would be biblical. It will happen again, the only thing we don’t know is when…
Thank you for displaying more intelligence than most scientist we get to see.

*@John Rand* i'm not sure about global warming, but if you think all these pollutants we're putting in the air, and plastics (which come from oil) we're dumping in the sea and on land are not going to eventually have some type of negative effect on us, then you're naive.

@@Ucandoit_ it’s more along the line of earths orbit. Earth hit a point in its orbit where it sunlight was hitting earth more directly. This causes more heat to be absorbed by the earth warming up the earth just enough to end the ice age. And then the earth eventually hits an orbit where sunlight is hitting it less directly doing the opposite

Thank you for sharing this!
I'd like to understand the mechanics of the ice cave. How, at that latitude, does it not only get below freezing, but maintain that temp fy thousands of years? It's not like it was under a mountaintop glacier, either.
I think it as under a glacier at some point 10,000 years ago. But since the cave penetrates so deep in the mountain, it still hasn't fully thawed out.
My ice despencer occasionally malfunctions and it gives me similar results..
Wait, so are they saying global warming is cyclical? Where have I heard that before?
From the “““conspiracy theorists””” that have debunked the absurd claims of the doomsday climate cultists.
It is a cycle but the main reason for the concern about climate change is that the cycle goes around every like 10 thousand years and in the last 100 years we’ve sped it up a lot. This is a problem because it means plants and animals won’t have enough time to evolve to the colder temperatures which could be bad.
truly stunning, absolutely beautiful
makes me wanna leave a crate of beer inside ther for the summer break
Yer beer would become alcoholic popsicles
It would explode while freezing.
its a cycle cooling and warming that's what the earth has done as long as it has been spinning
But you should buy these really expensive solar panels so you can charge the Tesla we force you to buy. Cha. Ching.
We have had 4 warmings, and 4 ice ages in 400,000 years, yet only one was warm enough.
Sometimes it get warm, sometimes it gets cold. Milankovich cycle.

great stuff here. thank you for producing it PBS.
I once thought I'd like caving. I didn't.
Long ago in a galaxy far away, I climb an aircraft tower thru a caged ladder. It was outside Chico CA in the '80's, at the abandoned "silos" a few miles out of town. I got to the top of the cage about 4' form the top where the cage ended. scariest 4' I climbed. Shaking and sweating. Once on the platform, it was chill for hours. Sometimes you gotta try something to know you don't like it.

I'd have to get paid.Im a shameless capitalist🐖like that
fascinating!
Imagine all the frozen breathes in there. Sure that cave has been visited for 1000's of years
Incredible amazing discoveries
Last I knew all Permafrost has been frozen since the last Ice Age. Whoa, whoa, whoa, shouldn't we be more worried about saving the planet instead of saving humanity.
We are still in an ice age. An ice age contains usually 2 to 10 “glaciations” More are coming
Thats so weird because the global temperature went up by 1 degree in 20 years. Would be a hell of a miracle if ice just started to appear in the arctic.
Beautiful!
So, the earth was warmer before then it got cooler. How many time did that happened?
Can’t wait until I can work in the field like this
Caves that dead end in ice? Makes me wonder.
About what?
If ice doesn't melt, it is basically just rock or soil.
Dump more rock and soil on top and unless it melts it will be likr that forever.
Neat cave.
Climate change is a natural cycle. The earth warms, it cools, it warms, it cools. It's ok.
Exactly. We will go back to another Ice Age in the future but before that the earth will warm up again. The cycle repeats itself until our Sun turns into a Red Giant and possibly engulfing Earth before becoming a white dwarf.
Facts
Its natural, but not nearly at the rate we have been going. Humans can definitely affect the earth cycles.
@@tommyrileydrums8743 Sorry, but no.
The largest contributor to global climate on the Earth is that gigantic fusion reactor 93 million miles away. You know, that main sequence type G star we affectionately call our Sun.
But please explain how you can justify your absolute arrogance in believing that we have more power than the combined might of 99.8% of ALL mass in the solar system?
@@deterrumeversor8680 I assume you have not heard of our ozone layer being affected by human polution i guess? That big old sun hurts alot more when we destroy our protection.
Just so beautiful!!!
I would feel very guilty entering such a microcosm. My mere breath could cause damage.
i wish i could eat some of the ice to taste ice age
Don't give yourself so much credit it's only been there for a million years I'm sure you're breathing on it's not gonna hurt it not even one little bit.
They should have taken some disco lights in.
Funny how I get this video in my recommendations after watching a video that showed how bad permafrost melting can be. They were explaining how viruses can come from the melting permafrost... we could be in for a real treat.
Guessing it wasn't a video made by scientists. A virus can't really survive permafrost conditions because it had to have been deposited while unfrozen and there aren't really any virus that live long outside of a suitable LIVING host. Once the host dies, virus are pretty well doomed too.
Fantastic !
Hey ty. Did you watch this?
Once visited an ice cave in New Mexico , I couldn't get my head around the ice in the desert!
Oh waaaaauw... Just.. Waaaauw😲❤️
Chilling information...
While humans are contributing to global warming, we are also in a natural warming cycle. I don’t even think we can slow it down.
We would have to eliminate 100% of carbon emissions. Shut down every volcano in the world. We have have to stop all dead life from decaying and somehow stop all sun activity. Then maybe we can stop climate change.
If anyone thinks, humans are the problem then scientists have them duped. Follow the money.
@@agon1963 Yeah, so we should give big oil companies another huge tax break, and cut down another rain forest just make sure, huh?
@@moemuggy4971 nope. My point was that humans are not creating all the temperature changes. Growing up in the early 70s, scientists said we were going to have a mini ice age. Then in the 90s, ice caps were going to melt now they call it climate change. The earth goes through cycles.
@@moemuggy4971 Nobody is saying that. The only place anyone is saying that is in the strawman fallacy memes the leftist climate cultists make.
@@moemuggy4971 ..
Environmentalism =/= Climate Cultism
You can care about the environment while not believing the insane doomsday alarmist claims of the climate cultists. In fact, from my experience, the people that reject the climate cult’s claims usually care WAY MORE about the environment than the climate cultists. And not only that, but they actually have ideas that are reasonable, feasible, practical solutions.
its good to know that it was actually warmer than it is now. I like global warming. We can get back into the parts that froze over before the ice age.
Well, not us exactly, but our kids can.
I bet there could be pre ice age relics in there somewhere
Ayyy Alberta, love this place
How did they melt 400,000 years ago? There were no emissions back then lol

Climate change happens.
Not all of it is human related however.
Based on solar cycles we should however be in a cooling phase.
Given climate change is happening we should be looking at accomodating for quite a bit of ocean level rise (bye bye Florida)
I recall an article about a silver mine, I think in Nevada, that had to be abandoned, due to permanent ice that made operations impossible-
No doubt due to global warming (climate change).
I’m surprised they don’t wear gear that better protects the cave, rebreather mask or n95 at least and sterile coveralls. Maybe it’s not a big deal.
smiling to myself thinking all the people nodding along till the last 90 seconds then grasp for the mouse screaming "NoT gLoBaL wArMiNg!"
It the ice is still from the ice age, doesn’t that mean we are still in that ice age???
It's like your car running on E, or empty... technically you're still on that tank of gas
(the cave was warm in that past) almost like there is a normal natural cycle to it
Genuine question: if greenhouse gases keep heat from the sun from escaping then how do they let it in in the first place? Some sort of atmospheric one-way mirror?
@Anderson That was way more information than I was expecting. The CO2 thing always felt fishy to me since plants need CO2 to grow. From everything I've seen the Earth is incredibly adept at keeping everything in balance, relatively speaking. We get some hot years and some cold years, but in the end life survives and the pendulum swings back the other direction.
@Anderson Cutting off the heat flow? Are you talking about the canal letting water pass through? Or are you talking about Panama acting as a barrier between the two oceans?
@Anderson Interesting. I wish I had a time machine to go back and watch those changes as they happened.
@Anderson Fingers crossed, though with great power comes corrupt politicians finding a way to use it against us. 😕
@Anderson I completely agree with you. I almost wish there was an aptitude test required in order to vote.
Wow, some commenters need a very tight hug. 🤔🤗💚🤙
In austria there is a cave "eisriesenwelt/höhle" (icegiantworld/cave) i was there for a few times and it is the largest cave thats always frozen on the world with a length of about 40km
Does the moisture in their breath impact the ice cave?
Yes thats prolly why craws spaces got bigger over time
Hopefully, it'll get much warmer in the next 10-20 years
?
Haven’t had this much snow dumped on my area in years 🤔
“This cave has been frozen since the last ice age”
Humans: I’m about to do what’s called a pro gamer move
So it was warm and flowing before, then there was an Ice Age that froze everything and theyre saying ‘yikes’ to temperatures possibly rising to the point where things return to flowing? Like, return to the way things were before the Ice Age? Sounds like things will be returning to normal. So what happens when all that carbon is released? Will it be a feeding frenzy for plant life?
Pretty much. Massive amounts of plant life, which of course, dies and lies on the ground, where it forms things like peat and eventually oil and coal. Natural cycle of life. Humans can either grow plants they eat or they can let the grass take over the planet.
How did you gain access?
Thanks brilliant
As the evidence suggests, the Earth cools and heats on its own with or without humanity. An incredible find.
I'm interested in the waters contents from before Man's pollution. Did they take samples to see how or if water has different molecules ?
Theres a conveyor belt system in the pacific like the one in the alantic they say the water on the bottom of it supposedly dates back to the dinosaurs
When water seeps through the ground, it's filtered. Above ground pollution might not be found.
What's with the self loathing
Water by definition is composed of only H20 molecules.
@@nobodyspecial4702 in itself. But other chemicals and molecules can attach themselves to it.
when they made that gate with that tiny door did they account for being able to get rescue equipment in there? if theres an emergency are they going to be able to rescue people or are people going to die because the door is to small?
Scientists accept that if they are doing science stuff and a cave collapses on them, no rescue effort is required. It's just recreational cavers who insist they be rescued no matter how stupidly dangerous the cave they want to explore is.
@@nobodyspecial4702 Citation needed.
@@xy4489 Check reality. When's the last time you heard of a scientific expedition getting trapped in a cave and requiring an international rescue. Oh, wait, it happened on last first of never.

Was previously thawed for thousands of years, yet scientists can sit there with a straight face and act like it's the end of the world when glaciers melt.
Sounds like a normal process.. The earth climate is cyclical and will always change. It's our responsibility to adapt to it. Not try to control it.
Absolutely
Sounds like you dont know what you are talking about and coming up with a belief that suits you best.
What caused the Earth to heat up back then was not humans. Now, it is. And we cannot adapt to the scale of the change. At least not without billions dying.
Yeah nah youre a moron. Were controlling it already but pumping chemicals into the atmosphere ruining it allowing more suns rays to hit the earth. Theres a hole the size of the continental united states torn straight out of our ozone layer that gets bigger and bigger. The more chemicals are pumped out the bigger that hole gets until we have no ozone and were mars. Boom. This has nothing to do with the earths cycles. Read a fuckin book
@@ayo886 The moron would be you. The ozone layer issue was dealt with decades ago. We no longer use CFCs anywhere on the planet so the ozone layer has been largely repaired by nature itself. Do yourself a favor, try reading books by actual scientists.
The temp will go up.
The ice will melt.
Ocean "conveyor" stops
Temps plumit over the ice caps
Ice Age occurs.
Fresh water stored over ice caps
Ocean "conveyor" starts
Ice Age ends.
Truly breathe taking literally I bet.
It was warmer 400,000 years ago than today, enough to melt the cave and have flowing water make the cave formations. However, CO2 levels were 100 ppm lower than today? If CO2 is the potent greenhouse gas they say it is, why isn’t it much hotter now? They said it right in the documentary. They need to explain. They also showed CO2 levels at 1000 ppm in the past with lush, warm forest growing, then showed a time of elevated CO2 where it was dry and hot, (horses got very small) as a warning. Which is it? Fact is, some parts will dry out as other parts become wetter. Adaption is the key to survival on this planet. Humans are the most well-suited mammals on this planet at adaptation due to our brains. I’m not sure that even the elevated CO2 levels now can prevent the cooling that is bound to happen looking at the past couple million year cycle.
Hmm Maybe it's like slamming the gas pedal in my car. It takes a little time to get up to speed
@@TheCosmosagan Were there cars 400k years ago?
Lots of Co2 is good for plants. Greenhouse gas is methane. Horses started small. A single tree absorbs Co2 at the rate of 48 lbs per year, 900-1200 PPM for a cannabis plant, and 1,000 to 1500 (max) is best for most plants. Adaption for humans just like other animals is way less the measure of adaptation or evolving due to our brains, but the water we drink, the food quality that we eat, air pollutants, stress are involved, and more, dude. Animals were adapting far many millions of years ago before we began to evolve.
@Anderson omg does Greta know about this?
@Anderson seems like the “experts” do mean to put us into an ice age again. I can’t figure out why all the climate change advocates keep buying beachfront property. They keep saying the Earth is warming but each winter here in Montana is exactly the same. COLD.
Interesting they said this cave was warm enough 400k years ago that the ice melted. The Earth goes through cycles we're only beginning to understand, that's why I'm highly sceptical how much humans are influencing our current warming period when we know the earth has been far warmer than it currently is today multiple times in history.
Do you really want to take the chance and assume the scientists, after decades of study, are wrong? 10-12,000 years ago, the world entered an unprecedented period of climate stability called the Holocene. It’s no coincidence that civilization developed when it did. Sure, there were periods when the planet warmed previously; but we were still living in small hunter-gatherer bands that could respond by moving to other places. We didn’t have a massive, worldwide interdependent civilization that relies on infrastructure we build. Using the far past as a way to justify doing nothing now makes no sense whatsoever. When the planet warmed previously, humans were in a very different situation. People weren’t less intelligent 50,000 years ago; they just didn’t have a long enough period of climate stability for civilization to develop. It’s not humanity itself or the world that’s threatened; it’s civilization. Humans will survive. But the majority of people will die and civilization with it.
Being skeptical is easy; facing hard truths is hard. No one wants to be the bearer of bad news. If we could continue using oil without any problem, no one would worry about it. It’s only because the science says otherwise that scientists are being those bearers of bad news.
And really, it doesn’t matter if you believe the scientists or not; there are many other good reasons to go green: lessening the health harming effects of pollution, and finding other energy sources as billions of people worldwide move to a more advanced lifestyle and the competition for scarce resources that will bring (i.e., wars over resources) are good reasons to find a better way. Either we can be leaders and sell green technologies to the world, or we can get left behind and become a second rate nation. It would be like if we tried to continue to power our nation on whale oil.
@@keirfarnum6811 Let me guess ...the answer is to cut a big check?
Nuclear power is ignored by all the "green" solutions. And that is how you know it's all a scam.
Yes. I will take the chance and call BS.
@@keirfarnum6811 so many things wrong or unable to be proven in your comment. Fact is the earth has been warmer multiple times in history, life has been more abundant in those times because there was more usable landmass. We should be skeptical because there's no way to prove how much or if any of our current warming period has anything to do with human activity. If our current warming period is purely caused by our activity then what warmed the earth in previous periods? How can we prove there isn't something else contributing or completely responsible for our current warming period?
Oil is finite but not in our lifetime or multiple generations from now, there's hundreds of years worth of oil in the US alone. I completely agreed about wanting to clean our energy usage up, but if you think cutting the US emissions in half or even completely to zero is going to make a difference then you are misinformed. We haven't even reached peak carbon output yet, china is adding coal plants every year to their grid and those are not clean burning by any stretch. In the last decade china has burned more coal than every other country in the world combined!
I think everything should be on the table for energy production, natural gas, modern coal plants that filter and carbon scrub their emissions, nuclear, solar, wind, hydroelectric and other renewables.
Damn right I'm skeptical of the current "science" many of these "scientist" are paid activist. There's big money in being a climate alarmist and funding for research in the areas they care about so they are more than happy to work people up over something that has happened multiple times before.
One of the biggest and most well known climate alarmist is Obama, yet he bought a $12 million dollar mansion in Martha's Vineyard with beachfront access. He's only a few feet above sea level yet he wants us in fear about sea level rise from global warming. Doesn't seem like he's too concerned, just like all the other alarmist that fly around in their private jets, own multiple mansions and own massive yachts. They've got bigger carbon footprints than a whole city block of residents, yet they want to put us in fear and tell us we've got 12 years to turn this around.
Nature will go on whether we do something or not. Personally, I think humans are too stupid and selfish to make decisions that have a positive impact in keeping our world clean and healthy. There have been many die offs in the past, there will be more in the future, it's unlikely our species will be there to see the results.
What about the smell? is the scent inside there different from outside?
You know, considering it's that old
Smells like old wet cave.
So if they take samples of the ice what will it tell us about climate at the time
It is sad how hardly anyone understands what permafrost melt actually means. Few comprehend what this actually entails.
@Anderson Hardly anyone debates that Earth will be fine for billions of years. The debate is what those changes mean for the human species.
@Anderson My bad I mistook your comment on Earth's historic CO2 levels as dismissing it's impact in the way that Creationists dismiss climate science.
A ice world that changed into a non-ice world .

It's the natural cycle for the planet. You don't hear about that anymore because climate change supporting doesn't permit anything that contradicts it to be reported.
Same lol…
What's with the gate? You can go in it but I can't?🤣
“Whoaaa, like total science bruh! Totally!”
You should just take some pictures and go home leave it alone
Scientist: "We have to stop global warming:
Same Scientist: " The earth has moved in these cycles since the beginning of time"
We’re just in an even worse cycle and we’ve unbalanced it
He said “this is one of the most amazing places I’ve been on this planet” 👀👀👀 mans is an alien
Makes you wounder what's behind that ice wall
And humans that have the ability, won’t do anything about it.
"Scientist restrict their visits every few years" - Says the mountain guide with a key to the cave.
We're gonna miss all this ice when it's gone.
That's the thing, they said this cave was warm enough 400k years ago that the ice melted. The Earth goes through cycles we're only beginning to understand, that's why I'm highly sceptical how much humans are influencing our current warming period when we know the earth has been far warmer than it currently is today multiple times in history.
I need to find this place and take down that fence to that entrance
I dream for the day when science gets separated from political-religion.....again.
Let’s go in and probably encounter a new virus or bacteria that’ll end humanity
We got one of those in iowa albeit a tiny one. There some almost extinct species of flowers that survived from the last ice age on a North slope on a hill were temperature are cool enough from the ice cave leaking cold air out of the grouns
Add another place onto my list of “places I want to visit but probably can’t”
Wow, the planet warms and cools kind of like a natural cycle. Hmm LOL
Ok. So nature has rhythms, Cycles. Dont be scared of change. There is plenty of room for the population in antarctica and the arctic if we swing to warmer temperature. Survive and adapt. Everything is going to be ok.
Anyone knw what lantern they had?
So is that water-deposited material basically Agate, just instead of being deposited inside volcanic rock, it is left on the outside of a rock wall?
Depending on the composition there are a number of different minerals deposited like that. Malachite comes to mind if there's a lot of copper in the surrounding rock to be leeched out by the water.
@@nobodyspecial4702 So it is agate then. Maybe with a little calcite inclusions and some others
Yes climate change happens in cycles. Antarctica was once subtropical, the groundwater table in Egypt was much higher and the region was tropical just a few thousand years ago. These things happen in cycles. Yes it should be in everyone's best interest to not waste consume less fuel and pollute less. However some political types have taken advantage of climate changes and turn it into an extortion racket.
What you are saying is partially true but the thing is, the average temperature of earth has been increasing almost exponentially since the start of the industrial revolution and this increase in temperature happened in less than 200 years. Climate change does happen in cycles but it does not happen in such a short span of time.
Tell us you don't understand climate change without telling us
@@SaintAnimus no one really does. Wen was the thermometer invented? To say climate change has accelerated since the industrial revolution is not really based on any data. It was a lot hotter during the Middle ages. And there was a little ice age before and during the revolutionary war. Ever see that picture of Washington crossing the Delaware? They were pushing blocks of ice out of their way.
@@SaintAnimus the fact is we've only been scientificly studying the weather patterns for about 100 years so that's basically 0 data being as humans have been on earth for 100,000 plus years and the earth itself is billions of years old... 100 years is less than a blink of the eyes worth of data
@@stephenm8100 There's thing called logic. We know T.Rex was a carnivore not cos we had a dude w/ a camera filming, but from making inferences. Idk exactly the methods if ur desperate I can look them up, but there are ways to estimate global temperatures w/o having a dude with a thermometer and a time machine.
