How did the mammals get that far underground? Let me guess a sinkhole. That is evidence of a thawing freezing cycle. Seems almost natural we are thawing right now.
I am a fossil researcher and that requires understanding Earth features which very few do.I did vids on these sinkholes when a Fla man was sucked in (2013). A Japanese researcher told me the Russians wanted to disscuss these holes with me....at the time there was 13. I spoke with the Russians (I think Academy of Science?? not sure long ago) about these holes as I studied them many years. I understand them and the gases and what can and cannot be done. This is a very dynamic situation we are facing. Under "Fair Use" I believe it is permitted to comment using your content (even copyright). I do hope you will understand I am trying to help and your info is VITAL...I LOVE PBS and NOVA
Obviously, the evidence of methane chimneys prove the earth is warming from the inside.... not caused by human emissions. Perhaps the moving of magnetic north is causing the melting of permafrost?
I lived in Anchorage in the 70s, and I recall local news reporting on permafrost thaw. The main complaint was the smell and the increased mosquito harvest. It was worrisome that the groundwater was thawing the permafrost and scientists we're studying it. I would say that this mega methane leakage is far greater than any methane produced by cattle around the world.
I remember learning about predictions of massive methane releases from melting permafrost a couple of decades ago. Why is Nova presenting this as a surprise to scientists? It's long been known that once methane starts pouring out of the permafrost would be a signal that the tipping point has been reached. Nova is making this sound as if it's a brand new idea. Does David H. Koch being one of Novas biggest sponsors have anything to do with that?
It isn't the fact that it's been releasing that has taken them by surprise. It is that the rate at which it is being released has taken scientists by surprise. It is far faster than they have predicted.
The tipping point is right. I don't understand how anyone can still argue that climate change is not real, it's very obvious just how real it is. I've lived in the Midwest for the past 22yrs, and in the past 8yrs (give or take) I've noticed a significant difference in our weather; the winters are warmer, it rarely snows anymore, the lakes & rivers no longer freeze over, spring lasts much longer, summers seem shorter. In the past 2yrs we've only had a small handful of summer days where the temp reached into the high 90's, our typical summer temp is high 90's into low 100's. I wish there was something we could do to fix our current problems.
@@pandap4ntz Has there ever been a time in the Earth's history that it's climate didn't change? I know this is a somewhat vague question based on what time period you use as a metric, but let's pick a ridiculously small time period in the scope of the Earth's age and say 1000 year blocks. I posit that the Earth's climate will never stop changing, whether it's man made or not. The most important question in my mind is: Does said change doom mankind or are we able to adapt? Man has adapted for hundreds of thousands of years....I wouldn't underestimate our ability to do so. Now, once our Sun goes Red Giant the party is over as far as Earth goes...but let's hope by then we are colonizing other planets/systems.
imagine being able to be wrong about everything you say and still get mountains of funding first it was global cooling then it was acid rain then the ozone was gone now its global warming all doom fantasy. I have a house in fl directly on the gulf of mexico the high water mark on my seawall has not moved in 20 years hell even the storms have been mild this decade

Yes indeed. I am from here in Kotzebue Alaska. Thanks to the scientific research on our area. We've always known that lake had some form of anomaly hole like structure way below the permafrost underneath the lakes. We have a lot going on, been doing this research all my life. This video tells a lot of whats happening here, and all over as well. #kotzebuealaska #thegallahornfamily

@@joew.3400 especially on the Florida coastline for example someone said in 40 years all the mansions by Miami on the coast will be underwater up to a few feet
Imagine what you could learn if you did your own research into the existence of atmospheric heating from government funded programs like H.A.R.R.P. and chemtrails instead of listening to this propaganda. 🤔
If you do the research, the Arctic is situated on top of what used to be a tropical rain forest. I believe it was before the last pole shift. Seems to me what's happening now is that as the region is warming up, that whole area that was once lush with life (before being re-situated, I suppose) is now beginning to decompose. If there was as much life thriving there before it became polar territory as it seems, this "thaw" is just the beginning of what could turn out to be a frighteningly enormous problem.
@@nicksshitbro True....that's what they say. The evidence seems to back it up, as the poles are clearly moving faster than man has ever recorded before. I'm fairly certain it's not just a "theory" as they know for sure that the land mass underneath the Arctic was indeed once a tropical rain forest. You can't fake the evidence for that, either it's there or it isn't. Seems to me like the "thaw" that is releasing all this decomp methane gas is further proof of material under the permafrost that is obviously decomposing.
@@alphaomega1351 No, but shit's going to be much more difficult and expensive. A lot of people will die from starvation, heat stroke, and hypothermia, but it's not going to kill everyone.

No; he stabs it again, and she goes to put the torch to the fire again! Melodramatic!!!!! And that permafrost tunnel, looks like a hollywood scifi set, very cool!
@@poop464 It's better to burn methane than it is to release it into the atmosphere. Methane is an order of magnitude a more effective barrier for infrared radiation than carbon dioxide, and burning it only creates carbon, water, and heat
I live in Fairbanks. I remember my dog walking in the ponds and releasing a trail of gas bubbles from the sediments. Back in the 80s I was lucky to get on a tour of the permafrost tunnel in Fox. Like the guide said in the video, the smell is unique, and it's amazing to see all the specimens thawing out of the ceiling and walls.
if SCIENTIST SAY AND AGREE THAT HUMANS ARE THE CAUSE OF GREEN HOUSE GASSES... THEN DO WHAT HITLER WOULD DO AND CULL 2/3rds of the POPULATION... Or we can do the same thing with ABORTION MOTHERS CULLING all the blacks and natives like PETOLA AND JOE BIDEN want. GET RID OF HUMANS and save the planet. PERHAPS lets get FOuchie to make COVID 2023 like he made 2019. IT WOULD BE A PERFECT WAY TO get the planet to have less carbon and methane gasses.
Living near the Arctic circle I've got my own little pond that is producing a small volume of gas in the late spring thaw. Suspected and probably methane, I've crudely collected and burned it at the source several times over the years. However the last two years I've tried to set the gas alight in my collector it's failed to ignite, actually snuffing out the torch I was using leading me to believe that the gas composition is changing to having greater CO2 levels than previous years. Spring thaw is coming soon and I'm anxious to see what kind of results I have this year. Just tickled not to not to be having the major conflagrations the Siberians are having... WOW.
Methane has a LEL (lower explosive limit) of 5-17%. This means that outside this concentration range you would see the same results you describe. Considering this it may be just as likely that you’re actually seeing higher concentration. Until you get expert analysis, I would err on the side of caution and assume the danger is still present.
Careful with those science experiments Cj lol. You may wanna recruit some grad students from U-Alaska Fairbanks since they seem to be the most involved (at least in this program) or other researchers in the area.
IDEA : Maybe these arctic "sinkholes", which are actually burst-holes, are the result of the thawing permafrost turning back to liquid, which would not only re-start the underground decomposition process, but also weaken the upper ground so it can no longer contain the gas & liquid pressures below ?
That's what I'm thinking because you can see debris around the rim that was expelled. If it was a sink hole earth from the rim would be falling into the hole. I also don't believe that the sink hole would be that perfect of a circle.
These methane bubbles occur in New Orleans Louisiana, USA area as well. Although they found some to be butane gas escaping from fractures in the natural salt mines where oil is stored pre-refining. Some have cause explosions and fires & evacuations - even of a permanent evacuation of an entire city. Accidental drilling into the wall of a salt mine can cause the escape of the butane gas. Sink holes, too...there are videos here on You Tube about it - whole trucks swallowed up by sinkholes.
Wasn't it in Louisiana that an old salt mine was drilled into causing a lake to drain? 😆 🤣 the sinkholes in Louisiana aren't caused by thawing permafrost though. Louisiana and here in Florida the sinkholes are MUCH more run-of-the-mill same for the methane bubbles, run-of-the-mill swamp gas...rotting vegetation etc. nothing out of the ordinary, geologically speaking. Unlike what's held down by permafrost. But I dont get how they know thats been locked up for millions of years. Seems to me like the Earth has been HOT(er) in our past. Before civilization? Research, on my part, is required. 🤔
Is oil in the Earth's crust a heat sink, insulating the crust from heat of the core of the earth? When oil is extracted, over time, the crust is absorbing core heat with the surface getting warmer.
Essential info in this documentary. These are the questions that remain: 1. Have the areas around the Russian tundra craters been tested with VLF to assess the presence of other deep chimneys of melting tundra? 2. Is the carbon isotopic signature from the melting tundra different from the fossil methane? 3. Is satellite imagery being used to track the development of tundra lakes?
@Sunny Quackers worried about an infinitesimal amount of fuel burnt by folks trying to find a solution to the non-existent problem you so desperately "need" a solution to... Yup makes "sense" to me!
These are called Pingos they are caused by aquifers and underground streams pressing up against the permafrost. They are driven by a frozen surface with geothermal warmth or moving subsurface water. Essentially cryo-vulcanoes. They would stop happening if the ground was thawing. They are not new, natives coined the name for them and knowledge of them goes back centuries. The makers of this video are trying to fool you because AGW alarmism is an excuse to control and tax you; and PBS in turn is funded by politicians.
@@nustada I'm sure these scientists are familiar with Pingos. Even if these are related to Pingos then the fact that they are exploding is new. Finding a phenomena in permafrost and equating it to those shown in the video (even though the two are very dissimilar, one being a hill and the other being a hole) does not mean the information in the video was wrong or deceptive. Pingos usually grow only a couple of centimetres per year, with Ibyuk Pingo growing at a rate of 2 cm (0.79 in) a year,[10] and the largest take decades or even centuries to form. The process that creates pingos is believed to be closely related to frost heaving. The base of the pingo tends to reach its maximum diameter in its early youth. This means pingos tend to grow higher rather than growing in diameter and height at the same time.[6] The height of pingos can range anywhere from 3 to 70 m (9.8 to 229.7 ft) and their diameters range from 30 to 1,000 m (98 to 3,281 ft).[1] The shape of pingos in usually circular. Smaller pingos tend to have curved tops whereas larger pingos usually have collapsed mounds or craters due to the melting of exposed ice.[1]

Watching this makes things like "Don't Look Up" seem very extremely realistic instead of farce. I don't have the answer, but society is definitely going to have to change with the tides, so to speak.
In the Amish ice House where food is stored one would put saw dust packed in with the ice the saw dust acted as a thermo blanket. The saw dust would absorb heat as the inside of the dust froze and acted like permafrost keeping the cubes of ice frozen longer. Saw dust a natural element is useful.
So it's a natural insulator. Got it. LOL If you soak the sawdust with water and lay a 1 inch layer on the floor, you can freeze it and use it for walls. 🙄
This is very concerning. Not only because methane is being released but because whatever bacteria and viruses are in that permafrost are waking up. We have no idea of what's being released and it's very possible that one or more of them are capable of causing diseases to which we have no immunity.
It's very rare for a disease to jump from animal to human. It's even more rare for a disease to jump from plant to human. It's not only unlikely but it's highly improbable that any disease or virus would be capable of infecting a human. Before you go and say Corona Virus jumped from animals to humans that isn't known for sure and it's also extremely rare. There are tons of diseases that commercial livestock get like Boop that you've probably never heard of because they only infect animals and don't jump to humans.
@@JonnoPlays - The possibility of human/animal transfer is not as rare as once believed. Swine flu, avian flu, Hantavirus, Bovine Spongiform Encephalopathy, Cryptosporidiosis, and the list goes on and on of diseases and afflictions that humans can acquire from animals, directly or indirectly, either by direct contact or through a vector is very real. Now lets add an unknown factor of ancient bacteria and viruses from melting permafrost to the mix of possibilities, some of which are completely unknown to modern man. Oh, and lets not forget about naturally occurring mutations.
Fantastic documentary from Nova again!! Thank you for the learning of our earth giving all incite to the truth around the world.this segment " Arctic sink holes!" Was an eye opener....❤❤it!!😊
Here's a theory, the tundra is warming, pockets of methane begin seeping to the surface, by chance lightning strikes the seeping spot and the exploding methane blows out, creating the raised rim and ejecta.
I like the theory. Would there be a way to calculate the saturation of methane needed to produce such a cylindrical shaft "70 metres deep with an icy lake at its bottom" and yet at the top are blast formations in a triangular pattern? It is as if a cylindrical formation existed already as a means of escape for ground methane. Was most of the sod melted from the heat and turned into a mist that fell back into the hole? If your theory is not workable then I only see one other theory that few have mentioned that most, but not me, scoff at.
I have to agree with All Time. I'm in my 50's and I remember hearing about the melting permafrost when I was in high school. Why wasn't the "Big Deal" over melting permafrost made back then. As the years have gone by I have wondered if what I heard back then was real or conjecture since nothing more was real said. I have lots of questions now.
Big oil has a lot of influence in politics and media, even more so in the past. People are now slowly learning the truth of how we're damaging the planet.
@@sailingaeolus who is this entity lol? I'm just talking about how the big oil industry is misleading the public, exactly the same way big tobacco did. Nothing new. No Qanon conspiracy required.
It was well-made. Great first exposure for those who don't know about methane release throughout the Arctic. BUT they did not give some key relevant facts, for example, they left viewers with the impression that the only Siberian methane holes/mounds are the less than a dozen that are in Yamal. They didn't mention that we know there are some 7,000 methane mounds throughout Siberia and that 400 are unexploded and swollen to the breaking point. Not completely forthcoming.
I can imagine a lightning strike igniting a methane seep, or even detonating a mixture of air and methane. That might explain the blown-out craters in the Russian tundra.
Wow now dats good observation... U ever seen dat movie da Truman Show? When da time comes, bet it'll be done just like dat.... da bolts 2 ignite da entire earth plain from All da gas.... Look at all these earth quakes.....Deliberate. All seems 2 b on a clock.... Then there's man n his reasoning 2 take Out da innocent... where is ah portal somebody!!!
It is more likely to be an explosive release of gas under building pressure on a thinning 'crust' - I don't see any indication that 'igniting' is required. If it were igniting it would be less of a problem since burning methane releases CO2 and methane is at least ten times worse (as a greenhouse gas) than CO2 (though it would still be a major problem since, as they say here, there is at least twice the levels of CO2 trapped in the tundra as is currently in the atmosphere)
@@DwayneShaw1 I gave that some thought, but I think the perfecty round craters better fit with a detonation model. I suppose one could look for scorched plant material in the ejecta as evidence.
@@jpdemer5 - and how did you determine there is a significant difference between the explosive effects of an ignited gas vs an explosive release of pressure? (except for a 'scorching' which doesn't appear to exist in the images?) How exactly did you determine only one type of explosion can produce a round shape? Are you aware that arctic lightening is very rare? the lightening increases with warming - but it's still pretty cold, and rare, in the region - to date. Where, exactly, did you get your degree in physics??????
Well, all it would really take is one spark of atmospheric friction or static discharge-whatever the realistic occurrence of like conditions would be in that geographical region...
I recently read an article about how salt from the Atlantic Ocean was increasing the salinity of the Arctic Ocean, which has had a lower salt content than the Atlantic and Pacific Oceans for millennia due to the presence of an underwater land barrier between Greenland and the Norwegian Island of Svalbard know as the Spitzbergen. This underwater land barrier, I understand, has been sinking and letting in more salt water into the Arctic Ocean and thus has cause increased salinity in the Arctic Ocean that makes sea ice more difficult to form resulting in what is called "dirty ice". This kind of ice doesn't reflect as much sun as the mostly freshwater sea ice that used to form primarily in the Arctic. This causes more sunlight to be absorbed and causes warming of the Arctic Ocean water that no doubt is contributing to the melting of the Arctic permafrost. I heard no discussion of this problem in the documentary. Did the contributing scientists not know about this phenomenon? Restoring the height of a sinking underwater land bridge seems like an impossible task meaning that the increase in Arctic Ocean salinity is probably an irreversible process that will lead to more permafrost melting and methane release from both permafrost organic matter and deep stores of fossil carbon. I don't think these processes are going to be reversed by humans. And shutting down fossil fuel use by humans to zero would have virtually no impact on what seems to be an inevitable increase in greenhouse gases. Perhaps we need to start adapting to these seemingly inevitable changes. Perhaps Antarctica, Canada, and Siberia will become tropical paradises again. I am not sure about what will happen to the rest of the planet. Will it all turn into a tropical paradise? Perhaps the amount or area of habitable human, plant, and animal land will expand rapidly in the near future. Would that be so bad? Another part of the global warming models that has been left out has been the role of cloud formation. Clouds cool the land and water beneath them. Perhaps this is another reason why models of global warming have been so far off.
They didn't TRAP the Co2 and Methane, they thrived on it. Our current temperature isn't all that different from where it was thousands of years ago when we plunged into a mini-ice age, and neither is the Co2. Co2 is a fraction of what it's been throughout Earth's history and our lack of plant diversity shows it. Plants thrive in high Co2 and heavily watered environments. This shouldn't come as a surprise really. What does surprise me is how little people know about Earth's climate history, as if the period of Ice Ages are the only times that matter when our Earth is 4.6 BILLION years old. We have climate records for specific parts of Earth during a very limited time scale. Furthermore, that scale of time is broken down into thousands of years yet scientists today try to use variations in daily weather patterns to draw conclusions on long-term changes. Even something occuring over a decade before reversing isn't long enough to call a trend. EVEN FURTHER, ocean levels were 400 feet lower 20,000 years ago than they are today. Humans were around when that occurred and survived. Humans were also around during the last interglacial period and survived, or rather, thrived, during the next ice age. So this idea that there is a catastrophe isn't based in reality.
Be careful the climate change people may come after you. It was never that warm before. Remember, we’re having global warming oops sorry climate change. You’re never supposed to tell anybody that it was warm before.
Exactly. Now it's warming up again and climate activists are trying to say that the human race is responsible. This would be happening and will continue regardless of whether man inhabited the planet or not. It just may be happening a little quicker due to our emissions.
I've been trying to learn more about interglacial periods lately as I knew that the earth had heated up and cooled down numerous times in its history and wanted to see to what extent they had happened before like maximum ice and lowest sea levels compared to high sea levels and not much ice and see how those compared to today's levels. I do think to deny humans have had an environmental impact on the planet is ridiculous but after investigating I think its very obvious that the climate would change dramatically naturally just like it had always done before I just find it strange that it's not more widely spoken of or taught in schools is it because the scientists think humans would just use it as an excuse to do nothing about the way they treat the planet or is it because many governments use climate change as a way of taxing the people, who knows? I am finding this stuff very interesting though and appreciate the comment/explanation.
Our tiny southeast Texas town of Daisetta has been dealing with sinkholes since the 70s. In 2008, we were on world news when one the size of several football fields formed within a day across the street from our high-school. Another, roughly a quarter the size of the original, suddenly appeared next to it. Several of us, myself included, had reported hearing gunshot like sounds around the same time each day before it, and were mocked. They aren't mocking now. As the ground warmed each afternoon, you could hear small explosions without a clear origin. If it's happening here, where we are actively pumping salt water into the ground, why wouldn't it happen where the environment is more delicate?
@@chefscorner7063 You ought to sit back and watch my fellow locals having fits about dead livestock appearing in the new waterhole. I'm waiting for them to start saying someone is sacrificing to Cthulu when, in reality, someone else is just feeding Bob the resident alligator.
So much oil has been pumped from the ground there. The giant crevices that was created is lowering the ground level. The sounds that you heard were more then like methane gas explosions.
@richardwood5262 The most frustrating thing is that this is a problem we struggle with on a state and national level, yet very little financial aid has been provided to even monitor the situation. Our grand scientific way of keeping watch on things is whether two t-posts driven into the ground have shifted. That's it. Texas A&M checked on things a few times after the main event, but the rest is on us and our nonexistsnt budget. We barely have 1300 residents. No money. A failing water system. Constant flooding from state building projects gone wrong, and the main way in and out of town that doesn't flood is currently under construction after the bridge (state highway) failed. I have every faith it will get worse, but we'll never be told anything. Such is life!
It was mentioned that methane is 100x more potent as a greenhouse gas than CO2 over a 10 year time frame. There's enough methane in the Arctic to turn the planet into Venus.
Nova is great I remember watching a Nova documentary about the Aborigines of Australia and my young mind was blown. That was sometime in mid 90s and this show still packs a punch
I recall our 2nd grade teacher, Ms Carter, rolling out a tv to have us watch NOVA. She was mean as a rattle snake but when she brought that TV out all was forgiven. 😉😆HAPPY 2023!
CO2 levels in the atmosphere are 430 parts per million (ppm). Put another way it is less than 1/2 of 1/10th of 1%. CO2 is the single most important plant nutrient and plants barely have enough, plants are actuely in slight distress due to the lack of CO2. In the past CO2 levels in the atmosphere have been a thousand times higher than they are now, the Planet did not cook, plants thrived and then the planet went into an iceage for millions of years. They are taking us for a ride and too many scientists are going along with it to stay on the gravy train.
The land bridges under water near Norway, Greenland, as well as the Bering strait have been sinking allowing more salt water into the Arctic Ocean, having a tremendous effect on the amount of sea ice that would form leading to less ice that protects Arctic coastlines and ice that would reflect more sunlight. Thus, leading to more warming in the Arctic. There's lots of natural phenomena that's changing the climate. Amazing documentary,wish this aspect was included in it bc it is major contributor to warmer weather.
I really liked your explanation of the facts. It does make perfect sense, when you put it plainly. I wish more people could see this video, along with this comment. Thanks for the extra info!
Planet earth went through many such cycles of warming and cooling. Humans cannot stop this no matter what effort we make. Solution for humans - mass migration
what an intriguing documentary! i really appreciated how it shed light on the complexities of climate change in such a captivating way. however, i can't help but wonder if these sinkholes are more of a natural occurrence rather than a direct consequence of human activity. it seems like we might be overestimating our impact sometimes. would love to hear what others think!
Outstanding! I loved this! I did not know about some of the grasses and things that were green and frozen in the permafrost for about 40,000 years and that was WILD to see them in that permafrost cave... Very eye opening to how our world is not standalone, but an accumulation of the worlds of the past, and we are all interconnected with them. Wish everyone had to watch this for schools! This was not taught in schools other than as "oh the ice caps are melting! stop driving cars and making carbon dioxide emissions!" This should be required viewing for any class that has a substitute teacher one day.
@@Jayf1981 idk man I don't listen to what people tell me I formed that idea myself.

Edit: oh shoot my bad I thought this was my comment lol I've got the poo brain
The "clock" is always ticking for all species that have ever lived on Earth, it's just a matter of time for us too. Earth will be fine, we will be gone.
our Biosphere is dynamic; the fact we're currently in an Ice Age there is only one direction global temperatures can go and its not a death sentence for humanity. there are many other factors that determine global temperatures other than the gases in the atmosphere. fear is a very useful tool - it keeps the Sheeple distracted and compliant. showing propaganda like this to your kids and not exploring the other factors is ignorant. you need to do your own research and stop being told what to think.
@@ericmartin2470 I'm sorry but I feel you are incorrect. I didn't simply watch one show and come to such a conclusion. It has been something I've studied and followed since the 1980's when potential problems started to become well known. We can look back pretty far into our earths past and what we are seeing is not normal and such sharp changes have never been normal. Regardless of who's right or wrong I'd hope that everyone can agree that polluting our environment is bad in way more ways than just climate change and that cleaning it up and teaching our kids how to be better stewards of this planet is a good thing.
@@Off-Grid indeed, i've watched the same "documentaries" - first it was global cooling, then global warming. its unclear if elevated CO^2 levels are the cause or result of higher average global temperatures - but everyone can agree there is a correlation. i dug-up 3 videos of PBS Space Time... the first 2 goes over the other factors i was talking about and the third talks about a solution - energy, the cause of the vast majority of debates on this topic. ua-cam.com/video/ztninkgZ0ws/v-deo.html ua-cam.com/video/wwGeCfWc100/v-deo.html ua-cam.com/video/ElulEJruhRQ/v-deo.html
These 'blow holes' look so perfectly round. I live in Florida where sinkholes are common. They never look like that. Of course, there is a difference in methane vs. limerock shifting.
Limerock "shifting"??? You must be high...Florida is sinking due to man made disasters like trying to drain swamps to build more houses...get it together man
They never look like that because yours are collapsing limestone. These are dirt and the more likely culprit is the Russian Air Force going to bomb rivers and ports. The bombs release prematurely.
@@billiamc1969 get it together man? I've lived here for almost 40 years and no doubt developers have a lot to do with it but I have seen the and lived in places where no matter where you dig, there is an abundance of limerock! When we get our rainy season, the lime begins to dissolve and move and holes , like the one in the woods near me begin to open. The town I live in also has underground springs that have been here for millennia. Between them and the rains, limerock gets dissolved little by little and the earth begins to shift.
I wish there were better news! Really captivating and well done, though. Wish this had been available in about 2007. Very shareable. I, too, wish they had slipped in the point about the Arctic Ocean about to flip from a reflector to an absorber.
@@brianbgood The Earth spends most of its time without Ice caps so life will go on. If humans don't make it, which is so extremely unlikely its probably not worth consideration, then so be it. Simply nature doing with nature does.
I'm confused as to why people think the climate would not change eventually and fast. There are so many ancient stories , seas crashing in, land collapsing into the waters, lands freezing over, jungles drying out and turning to desert , land splitting apart, lands becoming habitable, lands becoming inhabitable , islands appearing and others getting swallowe by the seas etc, it's how it's always been it's how it always will be, wether we are here or not
The difference is the rate of change. What happened in 10 thousand years, now is happening in 10. The difference is the flora and fauna that exists on the world today. When the arctic was lush and green, insects were a meter long, and humanoids did not exist.
The only things we know can trigger such rapid climate changes are volcanic winters or asteroid impacts. Now we're discovering and living through a 3rd way of drastic climate change. The only things that can happen faster are geological events such as volcanoes blowing up their cones in a violent explosive eruption or earthquakes that can split the ground in a matter of minutes.
But the politicians need to do something about it! But they are too busy taking money from the companies that are causing it and then denying it's even happening!!
I'm 67 years old and as a teenager he used to tell me that all the oil and other things we keep pumping out of the ground must be leaving huge voids deep underground. He thought that sinkholes may be the cause and that it could also throw the Earth out of balance. It sounded crazy at the time but today I'm wondering if he wasn't on to something 50 years ago.
@@elizabethsnowpaws3751 shifting the axis isn't throwing the earth out of balance lmao its shifting the axis. Artic sink holes also aren't massive earth quakes so they're not comparable
Lol you seriously think that pumping oil out of regions is going to throw the Earth out of balance? You’ve got to be kidding me. Earth has been pummeled by astroids as big as America one actually, that is called our wonderful moon, and it did not get out of balance, good grief. 😂
When I worked in Dead horse in the mid 70's there were miniature ponds as far as the eye could see in the permafrost. I didn't notice any change in the size or quantity of the ponds during my four year stay. It looked exactly like the ones shown on this show.

The more intelligent we become, the more we advance, definitely is not all good news. Mankind is not ready for all technologies we developed.

Circles occure in nature... However, can't stand the documentaries that are biased and sensationalized.

Absolutely, BS. methane indigenous to permafrost. Duh! Magma coming close to the surface. They mentioned it can't be lava ( magma on the ground) but did not mention magma. Mouthpiece for One World Order
There is a lake in northern Alberta that is full of methane as well, the western coast of Africa according to another documentary with the same amount as that lake you had as an example. How many other natural emissions are accruing else where globally ? Not all can be blamed on human activity. I do agree for everyone to really try to decrease the amount going into the atmosphere as well as dumping all kinds of items that can go into the trash cans, etc.
My understanding is that human contribution to greenhouse gasses since the dawn of the industrial age has contributed significantly to the initial warming over the last 150 years or so (which is more than in the last 5,000 years) , and even a slight increase of 1-2 degrees has created this snowball effect where the ice caps are melting, etc., and allowing this permafrost to melt in the first place. I don't think early climate change models had any idea that the thawing would have these cascading effects or end up thawing the fossil methane as well. In other words; we lit a match, that started a fire, that's about to run into a dynamite cache.
I live at about 87.00 W 39.89 N which is a long way from the Arctic, but for two long years I lived on an island, whose name I never learned, above Canada and well inside the Arctic circle. I built a dome there with materials I found out and about that trapped methane and I used that gas for light and heat in my shelter. Now I live very rural. I have also built a dome here I have used to trap methane. I was going to use this dome for methane from compost, However, I found this dome traps methane and holds it at about 7psig with sufficient flow to run a methane driven electrical generator with enough output to heat, light, and air condition a 3200 sq ft residence and 2200 sq ft barn and work shop, with a methane forge. This is methane that simply seeps out of the earth beneath the dome. I believe this to be much more prevalent than most people know. This patch of land also has a 6 acre pond that bubbles up methane. Earth's crust is leaking methane everywhere. As for the climate change computer models, the predictions made using them have yet to come to fruition.
What an amazing undertaking you managed. I have been really trying to envision the dome's you have built, your land area, the pond with the methane activity. Your story is also interesting.

The amount of work that these scientists have to conduct to gather sufficient data to prove or disprove their hypotheses is incredible. And to know all their work might be wrong and then need to go out there and collect more and more data is even more amazing.
Wait? They dont assume they have all the data? They dont assume they are right? They dont run on consensus? They sound like real scientists. What wrong with these people? They might not get the data they are hoping for. They might discover this is a natural cycle of some kind (most likely, but uncertain).
Or they are just taught the wrong things to begin with, because libtard education doesn’t teach anything it just convinces them of an already decided agenda !
@@WristWatcher we can see how it was a much warmer planet, for anyone say we have to stop the warming you have to ignore what we see to conclude this is the temperature that is the prefect for the planet. Waste billions$ on something we cannot control.

Can we get back to planting a crap ton of trees like we did in the 90s for some reason. We can have gardens of any type on the roofs of most every building. Old lants might kill us but maybe enough new plants could save us. I heard that bamboo is great for clean air and it's very useful.
I'm sorry but we would need more CO2 for that. You know, since plants breathe CO2. If we increased the CO2 in the atmosphere plants would LOVE IT..!! The jungles would go CRAZY..!! Now that is GREEN..!! Funny how politicians have convinced the sheeple that less CO2 makes things greener. Then taxed CO2 when they weren't looking. Just another ploy to separate you from your money.
The problem is that one year's growth of trees isn't going to correct burning 1000 years of tree growth worth of fossil fuel. All the cold that ever existed came from a 70 million year timeframe from when plants invented cellulose and bacteria and fungi finally developed the ability to break it down. And , also, we are burning it way faster than a thousand years per year. P. S. Trees don't sequester a significant amount of carbon until there 12 years old and they stopped sequestering significant amounts of carbon when they are about 25 years old.
In addition, there is the common misconception that most of the planet's oxygen comes from trees/vegetation. It doesn't. Most of the oxygen comes from the ocean.
What kind of creatures would be found in this lake? Sorry, I don't know that much about Alaska. I am always shocked and impressed when people enter murky waters, it frightens me. Great video.
Sink holes scare me to death....when I was a kid my grand parents had one open up in the back yard big enough to swallow 4 concrete trucks .....the scary thing to me is that it opened up right underneath the sand box i used to play in everyday.....it caused my grandparents to move...nobody would buy the house and eventually some 30 years later the house was bulldozed and shoved into the sink hole.
I'm sorry to hear about that. I know that would scare me to death. There's alot of sinkholes in Kentucky. I'm originally from Cincinnati and I've seen several sink holes south of me , I can't remember where too many years ago.
@@arlenecraig4028 well you don't live to awful far from where we live and the sink hole happened...we live in Floyd county Indiana which is across the Ohio river from Louisville KY in indians.

During the Cretacious Era, CO2 concentration in the atmosphere was 10 times as high as it is today, and Earth was teeming with life. It would suffocate humans, though. If the Arctic thawed, it would be covered with forests, which would use and incorporate a lot of carbon.
@@MegaMeaty Just to say it's hard to come to any definitive conclusions about what will happen. There could be mitigating circumstances that encourage rather than destroy life forms. I didn't know about the snowball era - thanks for the info.
How do you know it would suffocate humans? How do you know if when the C02 rises so does the oxygen level as the plants have more to use and in return give off more oxygen. C02 is not dangerous at all to humans if there is enough oxygen to compensate. If animals can survive the high C02 levels then so can humans so teaming with life would also include humans.
Humans wouldn't suffocate, we'd be just fine. This is such a big issue (the doomsday that we are destroying the Earth Wall-E style) I have with Space Frontier people. As if terraforming a planet or star that has no atmosphere or water is easier than surviving our planet going through another cycle. Sure, it's a dramatic cycle, but so was the astroid that wiped out most of the dinosaurs, and mammals still made it through. We have more time than they did to acclimate. We will have even more time if we can slow down the progression. We won't suffocate, we will likely thrive, after we have a shaving of our population for a bit. Humans are smart. Heck, we might even get taller. Bring back the giant sloths and Titanoboa!

Is there a way we can capture the methane as it's coming through the perma frost and use it as a commodity? Maybe using it in a way that the gases given off of how we use it will not damage the atmosphere.
possibly, but methane oxidises to create even more CO2 its extremely potent. To capture and use it in a way to not damage the atmosphere is impossible because you're going to be damaging the atmosphere. Unless you somehow capture all the methane that's seeping it out, harnessing it and capturing the CO2 it turns into and then storing that deep underground well in the bedrock of the Earth.
The methane from the permafrost is all over the artic, I’m pretty sure folks already been mentioning that, and there’s forests and other lands sinking, it is too dangerous to start putting equipment to just extract the methane alone, and there’s tons of methane gases from the permafrost since the planet is continuing to rise and warm up, she will continue to grow while some of us will continue to deny the facts and try to cover things up until the planet decides when she wants her planet how she wants it.
@@staywoke2198 People love to be scared out of their wits! "Fear" not only sells, it paralyzes people and allows them to easily be manipulated. Many people want this, as it absolves them of the obligation to think for themselves or be responsible for anything, and they don't have to make any difficult decisions in life. They can just parrot what they are told to believe .. and that, in their pea brains, can substitute as some sort of real contribution to the discussion. I think we're in for a long battle for very survival of human individualism. We are almost literally turning into insects. We are actually, in many ways that can be demonstrated, developing a "hive mind". And .. unlike actual insects who can rebel and choose to go against the current .. we are increasingly being prevented from mounting any resistance whatsoever.
Diving on a source of gas bubbles can be deadly. If the concentration of gas is high enough, you can sink down and find yourself trapped for lack of buoyancy. The bubbles can emerge from an underground source, but it can also happen in turbulent, tumbling rivers/creeks such as the Strid at Bolton Abbey, Yorkshire.
The Earth never stays the same. We have had several MASSIVE changes on earth over eons. Not due to human activity. Its because of the cycles our galaxy and solar system and planets go through. New creatures evolve to enjoy the new earth each time.

It's not the temperature we need to be concerned with, it's the composition of the atmosphere. We can keep cool if it gets too hot, we have no options if the air is unbreathable.
An upward explosion does create a symmetrical hole unless the material on the surface is not of the same consistency, like the shape of an air bubble rising in the water.

I worked in the oil and field for many years. I think there may be a Way too recover some of the gas as it makes it to the surface Small recovery machines that can be moved around.
I get your thinking but that would just compound the problem. We need to put all sources on the grid and only run big industrials and supply gas heat with fossil sources. The rest could energize cars, small industrials, etc. The Pickens plan. ;=))
@@SaltyMinorcan No on said to drill just capture the gas making it to the surface. It’s coming to the surface anyway. There is no way to put back the thermo frost. .
These are not caused by gas, but permafrost and aquifers or subsurface rivers. They are called Pingos. The maker of this video is trying to fool you. The soil below permafrost will always release some methane when exposed to the atmosphere, it is barely enough to detect, not enough to run anything off of.

How did the mammals get that far underground? Let me guess a sinkhole. That is evidence of a thawing freezing cycle. Seems almost natural we are thawing right now.

Obviously, the evidence of methane chimneys prove the earth is warming from the inside.... not caused by human emissions. Perhaps the moving of magnetic north is causing the melting of permafrost?
Ppppp9
I lived in Anchorage in the 70s, and I recall local news reporting on permafrost thaw. The main complaint was the smell and the increased mosquito harvest. It was worrisome that the groundwater was thawing the permafrost and scientists we're studying it. I would say that this mega methane leakage is far greater than any methane produced by cattle around the world.
Based on what? And your feelings don't count.
I’d say they are about the same amount but the more thaw the more methane will be added so it’s an inverse effect.

I remember learning about predictions of massive methane releases from melting permafrost a couple of decades ago. Why is Nova presenting this as a surprise to scientists? It's long been known that once methane starts pouring out of the permafrost would be a signal that the tipping point has been reached. Nova is making this sound as if it's a brand new idea. Does David H. Koch being one of Novas biggest sponsors have anything to do with that?
It isn't the fact that it's been releasing that has taken them by surprise. It is that the rate at which it is being released has taken scientists by surprise. It is far faster than they have predicted.
And it's releasing fossil methane reserves. What's next, mass methane hydrate melts?
The tipping point is right. I don't understand how anyone can still argue that climate change is not real, it's very obvious just how real it is. I've lived in the Midwest for the past 22yrs, and in the past 8yrs (give or take) I've noticed a significant difference in our weather; the winters are warmer, it rarely snows anymore, the lakes & rivers no longer freeze over, spring lasts much longer, summers seem shorter. In the past 2yrs we've only had a small handful of summer days where the temp reached into the high 90's, our typical summer temp is high 90's into low 100's. I wish there was something we could do to fix our current problems.
@@pandap4ntz Has there ever been a time in the Earth's history that it's climate didn't change?

If you do the research, the Arctic is situated on top of what used to be a tropical rain forest. I believe it was before the last pole shift. Seems to me what's happening now is that as the region is warming up, that whole area that was once lush with life (before being re-situated, I suppose) is now beginning to decompose. If there was as much life thriving there before it became polar territory as it seems, this "thaw" is just the beginning of what could turn out to be a frighteningly enormous problem.
This would coincide with the theory that the poles are currently shifting again, as per the 25,600 year cycle.
@@nicksshitbro True....that's what they say. The evidence seems to back it up, as the poles are clearly moving faster than man has ever recorded before. I'm fairly certain it's not just a "theory" as they know for sure that the land mass underneath the Arctic was indeed once a tropical rain forest. You can't fake the evidence for that, either it's there or it isn't. Seems to me like the "thaw" that is releasing all this decomp methane gas is further proof of material under the permafrost that is obviously decomposing.

Living near the Arctic circle I've got my own little pond that is producing a small volume of gas in the late spring thaw.
Suspected and probably methane, I've crudely collected and burned it at the source several times over the years. However the last two years I've tried to set the gas alight in my collector it's failed to ignite, actually snuffing out the torch I was using leading me to believe that the gas composition is changing to having greater CO2 levels than previous years.
Spring thaw is coming soon and I'm anxious to see what kind of results I have this year. Just tickled not to not to be having the major conflagrations the Siberians are having... WOW.
Maybe a sign the concentration is lowering. Be safe
@
Methane has a LEL (lower explosive limit) of 5-17%. This means that outside this concentration range you would see the same results you describe. Considering this it may be just as likely that you’re actually seeing higher concentration. Until you get expert analysis, I would err on the side of caution and assume the danger is still present.
Fire up that tiktok and take us on the journey together
Careful with those science experiments Cj lol. You may wanna recruit some grad students from U-Alaska Fairbanks since they seem to be the most involved (at least in this program) or other researchers in the area.
"how fast it's going to happen, we don't know"
Whenever they say that, it happens much faster than anyone predicted
IDEA : Maybe these arctic "sinkholes", which are actually burst-holes, are the result of the thawing permafrost turning back to liquid, which would not only re-start the underground decomposition process, but also weaken the upper ground so it can no longer contain the gas & liquid pressures below ?
Suspicious Observers
That makes sense. And we are observing within years, not millions of years.
Isnt that what the video said?
That's what I'm thinking because you can see debris around the rim that was expelled. If it was a sink hole earth from the rim would be falling into the hole. I also don't believe that the sink hole would be that perfect of a circle.
Thawing permafrost..... There were no SUVs or humans back then to thaw it 🤔🤔🤔🤔🤔....
These methane bubbles occur in New Orleans Louisiana, USA area as well. Although they found some to be butane gas escaping from fractures in the natural salt mines where oil is stored pre-refining. Some have cause explosions and fires & evacuations - even of a permanent evacuation of an entire city. Accidental drilling into the wall of a salt mine can cause the escape of the butane gas. Sink holes, too...there are videos here on You Tube about it - whole trucks swallowed up by sinkholes.
Dear Govinda, Thank you for pointing this out. Yes, you are right. I am from New Orleans and am familiar with the phenomena.
Wasn't it in Louisiana that an old salt mine was drilled into causing a lake to drain? 😆 🤣 the sinkholes in Louisiana aren't caused by thawing permafrost though. Louisiana and here in Florida the sinkholes are MUCH more run-of-the-mill same for the methane bubbles, run-of-the-mill swamp gas...rotting vegetation etc. nothing out of the ordinary, geologically speaking. Unlike what's held down by permafrost. But I dont get how they know thats been locked up for millions of years. Seems to me like the Earth has been HOT(er) in our past. Before civilization? Research, on my part, is required. 🤔
It's harder to preach about global warming in that case so they dont mention it

These are called Pingos they are caused by aquifers and underground streams pressing up against the permafrost. They are driven by a frozen surface with geothermal warmth or moving subsurface water. Essentially cryo-vulcanoes.
They would stop happening if the ground was thawing. They are not new, natives coined the name for them and knowledge of them goes back centuries.
The makers of this video are trying to fool you because AGW alarmism is an excuse to control and tax you; and PBS in turn is funded by politicians.
@@nustada I'm sure these scientists are familiar with Pingos. Even if these are related to Pingos then the fact that they are exploding is new. Finding a phenomena in permafrost and equating it to those shown in the video (even though the two are very dissimilar, one being a hill and the other being a hole) does not mean the information in the video was wrong or deceptive.
Pingos usually grow only a couple of centimetres per year, with Ibyuk Pingo growing at a rate of 2 cm (0.79 in) a year,[10] and the largest take decades or even centuries to form. The process that creates pingos is believed to be closely related to frost heaving. The base of the pingo tends to reach its maximum diameter in its early youth. This means pingos tend to grow higher rather than growing in diameter and height at the same time.[6] The height of pingos can range anywhere from 3 to 70 m (9.8 to 229.7 ft) and their diameters range from 30 to 1,000 m (98 to 3,281 ft).[1] The shape of pingos in usually circular. Smaller pingos tend to have curved tops whereas larger pingos usually have collapsed mounds or craters due to the melting of exposed ice.[1]

In the Amish ice House where food is stored one would put saw dust packed in with the ice the saw dust acted as a thermo blanket. The saw dust would absorb heat as the inside of the dust froze and acted like permafrost keeping the cubes of ice frozen longer. Saw dust a natural element is useful.

It's very rare for a disease to jump from animal to human. It's even more rare for a disease to jump from plant to human. It's not only unlikely but it's highly improbable that any disease or virus would be capable of infecting a human. Before you go and say Corona Virus jumped from animals to humans that isn't known for sure and it's also extremely rare.

so was your mom!
Here's a theory, the tundra is warming, pockets of methane begin seeping to the surface, by chance lightning strikes the seeping spot and the exploding methane blows out, creating the raised rim and ejecta.
I like the theory. Would there be a way to calculate the saturation of methane needed to produce such a cylindrical shaft "70 metres deep with an icy lake at its bottom" and yet at the top are blast formations in a triangular pattern? It is as if a cylindrical formation existed already as a means of escape for ground methane. Was most of the sod melted from the heat and turned into a mist that fell back into the hole? If your theory is not workable then I only see one other theory that few have mentioned that most, but not me, scoff at.
why not? any recordings out there? maybe sat photos?
Is it better to let the CH4 burn? or suppress it's ignition?
Accelerating climate change. How nice.
Even if lightning didn't strike the lack of pressure would have the same effect i suppose.

It was well-made. Great first exposure for those who don't know about methane release throughout the Arctic. BUT they did not give some key relevant facts, for example, they left viewers with the impression that the only Siberian methane holes/mounds are the less than a dozen that are in Yamal. They didn't mention that we know there are some 7,000 methane mounds throughout Siberia and that 400 are unexploded and swollen to the breaking point. Not completely forthcoming.

It's a review of a particular phenomenon.
@@asecretturning Its spin. Looking at a "particular" phenomenon would include the entire pie, not just a tiny slice of the pie.
I can imagine a lightning strike igniting a methane seep, or even detonating a mixture of air and methane. That might explain the blown-out craters in the Russian tundra.

It is more likely to be an explosive release of gas under building pressure on a thinning 'crust' - I don't see any indication that 'igniting' is required. If it were igniting it would be less of a problem since burning methane releases CO2 and methane is at least ten times worse (as a greenhouse gas) than CO2 (though it would still be a major problem since, as they say here, there is at least twice the levels of CO2 trapped in the tundra as is currently in the atmosphere)
@@DwayneShaw1 I gave that some thought, but I think the perfecty round craters better fit with a detonation model. I suppose one could look for scorched plant material in the ejecta as evidence.
That was my first thought and if so more to go. Very good, and thanks, they should have suspected the same thing, shame on them.
@@jpdemer5 - and how did you determine there is a significant difference between the explosive effects of an ignited gas vs an explosive release of pressure? (except for a 'scorching' which doesn't appear to exist in the images?) How exactly did you determine only one type of explosion can produce a round shape?
Are you aware that arctic lightening is very rare? the lightening increases with warming - but it's still pretty cold, and rare, in the region - to date.
Where, exactly, did you get your degree in physics??????
Wouldn't a lightning strike ignite a methane source on the surface and potentially result in a large explosion?
Very clever.
@@SchemeTintFocus Oh, well, thank you...
Well, all it would really take is one spark of atmospheric friction or static discharge-whatever the realistic occurrence of like conditions would be in that geographical region...

I recently read an article about how salt from the Atlantic Ocean was increasing the salinity of the Arctic Ocean, which has had a lower salt content than the Atlantic and Pacific Oceans for millennia due to the presence of an underwater land barrier between Greenland and the Norwegian Island of Svalbard know as the Spitzbergen. This underwater land barrier, I understand, has been sinking and letting in more salt water into the Arctic Ocean and thus has cause increased salinity in the Arctic Ocean that makes sea ice more difficult to form resulting in what is called "dirty ice". This kind of ice doesn't reflect as much sun as the mostly freshwater sea ice that used to form primarily in the Arctic. This causes more sunlight to be absorbed and causes warming of the Arctic Ocean water that no doubt is contributing to the melting of the Arctic permafrost. I heard no discussion of this problem in the documentary. Did the contributing scientists not know about this phenomenon? Restoring the height of a sinking underwater land bridge seems like an impossible task meaning that the increase in Arctic Ocean salinity is probably an irreversible process that will lead to more permafrost melting and methane release from both permafrost organic matter and deep stores of fossil carbon. I don't think these processes are going to be reversed by humans. And shutting down fossil fuel use by humans to zero would have virtually no impact on what seems to be an inevitable increase in greenhouse gases. Perhaps we need to start adapting to these seemingly inevitable changes. Perhaps Antarctica, Canada, and Siberia will become tropical paradises again. I am not sure about what will happen to the rest of the planet. Will it all turn into a tropical paradise? Perhaps the amount or area of habitable human, plant, and animal land will expand rapidly in the near future. Would that be so bad? Another part of the global warming models that has been left out has been the role of cloud formation. Clouds cool the land and water beneath them. Perhaps this is another reason why models of global warming have been so far off.

Interesting how green and warm Alaska used to be when all those plants 🌱 were growing that trapped the CO2 and methane.
They didn't TRAP the Co2 and Methane, they thrived on it. Our current temperature isn't all that different from where it was thousands of years ago when we plunged into a mini-ice age, and neither is the Co2. Co2 is a fraction of what it's been throughout Earth's history and our lack of plant diversity shows it. Plants thrive in high Co2 and heavily watered environments. This shouldn't come as a surprise really.
What does surprise me is how little people know about Earth's climate history, as if the period of Ice Ages are the only times that matter when our Earth is 4.6 BILLION years old. We have climate records for specific parts of Earth during a very limited time scale. Furthermore, that scale of time is broken down into thousands of years yet scientists today try to use variations in daily weather patterns to draw conclusions on long-term changes. Even something occuring over a decade before reversing isn't long enough to call a trend.
EVEN FURTHER, ocean levels were 400 feet lower 20,000 years ago than they are today. Humans were around when that occurred and survived. Humans were also around during the last interglacial period and survived, or rather, thrived, during the next ice age. So this idea that there is a catastrophe isn't based in reality.
Be careful the climate change people may come after you.
It was never that warm before.
Remember, we’re having global warming oops sorry climate change. You’re never supposed to tell anybody that it was warm before.
Exactly. Now it's warming up again and climate activists are trying to say that the human race is responsible. This would be happening and will continue regardless of whether man inhabited the planet or not. It just may be happening a little quicker due to our emissions.
Yes, plenty of CO2.
.
I've been trying to learn more about interglacial periods lately as I knew that the earth had heated up and cooled down numerous times in its history and wanted to see to what extent they had happened before like maximum ice and lowest sea levels compared to high sea levels and not much ice and see how those compared to today's levels. I do think to deny humans have had an environmental impact on the planet is ridiculous but after investigating I think its very obvious that the climate would change dramatically naturally just like it had always done before I just find it strange that it's not more widely spoken of or taught in schools is it because the scientists think humans would just use it as an excuse to do nothing about the way they treat the planet or is it because many governments use climate change as a way of taxing the people, who knows? I am finding this stuff very interesting though and appreciate the comment/explanation.
Our tiny southeast Texas town of Daisetta has been dealing with sinkholes since the 70s. In 2008, we were on world news when one the size of several football fields formed within a day across the street from our high-school. Another, roughly a quarter the size of the original, suddenly appeared next to it. Several of us, myself included, had reported hearing gunshot like sounds around the same time each day before it, and were mocked. They aren't mocking now. As the ground warmed each afternoon, you could hear small explosions without a clear origin. If it's happening here, where we are actively pumping salt water into the ground, why wouldn't it happen where the environment is more delicate?
I thought the start of your comment would make a great start to a story, then it turned into one. ;)

So much oil has been pumped from the ground there. The giant crevices that was created is lowering the ground level. The sounds that you heard were more then like methane gas explosions.
@richardwood5262 The most frustrating thing is that this is a problem we struggle with on a state and national level, yet very little financial aid has been provided to even monitor the situation. Our grand scientific way of keeping watch on things is whether two t-posts driven into the ground have shifted. That's it. Texas A&M checked on things a few times after the main event, but the rest is on us and our nonexistsnt budget. We barely have 1300 residents. No money. A failing water system. Constant flooding from state building projects gone wrong, and the main way in and out of town that doesn't flood is currently under construction after the bridge (state highway) failed. I have every faith it will get worse, but we'll never be told anything. Such is life!
The question is not "Can the sinkholes add to global warming?",
but, rather, "how much can they increase the speed and severity of global warming?"
It's not the sink holes, but the methane and other greenhouse gasses. But other than that, yes, it is a hard variable to predict in the equation.
It was mentioned that methane is 100x more potent as a greenhouse gas than CO2 over a 10 year time frame. There's enough methane in the Arctic to turn the planet into Venus.

Where can I find all of their documentaries?
CO2 levels in the atmosphere are 430 parts per million (ppm). Put another way it is less than 1/2 of 1/10th of 1%. CO2 is the single most important plant nutrient and plants barely have enough, plants are actuely in slight distress due to the lack of CO2.
In the past CO2 levels in the atmosphere have been a thousand times higher than they are now, the Planet did not cook, plants thrived and then the planet went into an iceage for millions of years.
They are taking us for a ride and too many scientists are going along with it to stay on the gravy train.
The land bridges under water near Norway, Greenland, as well as the Bering strait have been sinking allowing more salt water into the Arctic Ocean, having a tremendous effect on the amount of sea ice that would form leading to less ice that protects Arctic coastlines and ice that would reflect more sunlight. Thus, leading to more warming in the Arctic. There's lots of natural phenomena that's changing the climate. Amazing documentary,wish this aspect was included in it bc it is major contributor to warmer weather.
yup and there was a land bridge between europe proper and the UK and even from asia to australia.

what an intriguing documentary! i really appreciated how it shed light on the complexities of climate change in such a captivating way. however, i can't help but wonder if these sinkholes are more of a natural occurrence rather than a direct consequence of human activity. it seems like we might be overestimating our impact sometimes. would love to hear what others think!
Outstanding! I loved this! I did not know about some of the grasses and things that were green and frozen in the permafrost for about 40,000 years and that was WILD to see them in that permafrost cave...

I could imagine it being an actual firey explosion, you get a sinkhole on a methane deposit and it causes compression ignition of the methane.
Limerock "shifting"??? You must be high...Florida is sinking due to man made disasters like trying to drain swamps to build more houses...get it together man
They never look like that because yours are collapsing limestone.
These are dirt and the more likely culprit is the Russian Air Force going to bomb rivers and ports. The bombs release prematurely.
@@billiamc1969 get it together man? I've lived here for almost 40 years and no doubt developers have a lot to do with it but I have seen the and lived in places where no matter where you dig, there is an abundance of limerock! When we get our rainy season, the lime begins to dissolve and move and holes , like the one in the woods near me begin to open. The town I live in also has underground springs that have been here for millennia. Between them and the rains, limerock gets dissolved little by little and the earth begins to shift.

I'm confused as to why people think the climate would not change eventually and fast. There are so many ancient stories , seas crashing in, land collapsing into the waters, lands freezing over, jungles drying out and turning to desert , land splitting apart, lands becoming habitable, lands becoming inhabitable , islands appearing and others getting swallowe by the seas etc, it's how it's always been it's how it always will be, wether we are here or not
The only thing constant about this planet is that it is ALWAYS changing.
The difference is the rate of change. What happened in 10 thousand years, now is happening in 10.
The difference is the flora and fauna that exists on the world today. When the arctic was lush and green, insects were a meter long, and humanoids did not exist.
The only things we know can trigger such rapid climate changes are volcanic winters or asteroid impacts. Now we're discovering and living through a 3rd way of drastic climate change. The only things that can happen faster are geological events such as volcanoes blowing up their cones in a violent explosive eruption or earthquakes that can split the ground in a matter of minutes.

There is a lake in northern Alberta that is full of methane as well, the western coast of Africa according to another documentary with the same amount as that lake you had as an example. How many other natural emissions are accruing else where globally ? Not all can be blamed on human activity. I do agree for everyone to really try to decrease the amount going into the atmosphere as well as dumping all kinds of items that can go into the trash cans, etc.
My understanding is that human contribution to greenhouse gasses since the dawn of the industrial age has contributed significantly to the initial warming over the last 150 years or so (which is more than in the last 5,000 years) , and even a slight increase of 1-2 degrees has created this snowball effect where the ice caps are melting, etc., and allowing this permafrost to melt in the first place. I don't think early climate change models had any idea that the thawing would have these cascading effects or end up thawing the fossil methane as well. In other words; we lit a match, that started a fire, that's about to run into a dynamite cache.
I live at about 87.00 W 39.89 N which is a long way from the Arctic, but for two long years I lived on an island, whose name I never learned, above Canada and well inside the Arctic circle. I built a dome there with materials I found out and about that trapped methane and I used that gas for light and heat in my shelter. Now I live very rural. I have also built a dome here I have used to trap methane. I was going to use this dome for methane from compost, However, I found this dome traps methane and holds it at about 7psig with sufficient flow to run a methane driven electrical generator with enough output to heat, light, and air condition a 3200 sq ft residence and 2200 sq ft barn and work shop, with a methane forge. This is methane that simply seeps out of the earth beneath the dome. I believe this to be much more prevalent than most people know. This patch of land also has a 6 acre pond that bubbles up methane. Earth's crust is leaking methane everywhere. As for the climate change computer models, the predictions made using them have yet to come to fruition.

I'm sorry but we would need more CO2 for that. You know, since plants breathe CO2. If we increased the CO2 in the atmosphere plants would LOVE IT..!! The jungles would go CRAZY..!! Now that is GREEN..!! Funny how politicians have convinced the sheeple that less CO2 makes things greener. Then taxed CO2 when they weren't looking. Just another ploy to separate you from your money.
The problem is that one year's growth of trees isn't going to correct burning 1000 years of tree growth worth of fossil fuel.
All the cold that ever existed came from a 70 million year timeframe from when plants invented cellulose and bacteria and fungi finally developed the ability to break it down.
And , also, we are burning it way faster than a thousand years per year.
P. S. Trees don't sequester a significant amount of carbon until there 12 years old and they stopped sequestering significant amounts of carbon when they are about 25 years old.
In addition, there is the common misconception that most of the planet's oxygen comes from trees/vegetation. It doesn't. Most of the oxygen comes from the ocean.

During the Cretacious Era, CO2 concentration in the atmosphere was 10 times as high as it is today, and Earth was teeming with life. It would suffocate humans, though. If the Arctic thawed, it would be covered with forests, which would use and incorporate a lot of carbon.
During Iceball earth - nothing we know survived. Does that mean you have a point? I don't see one.
@@MegaMeaty Just to say it's hard to come to any definitive conclusions about what will happen. There could be mitigating circumstances that encourage rather than destroy life forms. I didn't know about the snowball era - thanks for the info.
How do you know it would suffocate humans? How do you know if when the C02 rises so does the oxygen level as the plants have more to use and in return give off more oxygen. C02 is not dangerous at all to humans if there is enough oxygen to compensate. If animals can survive the high C02 levels then so can humans so teaming with life would also include humans.
Humans wouldn't suffocate, we'd be just fine. This is such a big issue (the doomsday that we are destroying the Earth Wall-E style) I have with Space Frontier people. As if terraforming a planet or star that has no atmosphere or water is easier than surviving our planet going through another cycle. Sure, it's a dramatic cycle, but so was the astroid that wiped out most of the dinosaurs, and mammals still made it through. We have more time than they did to acclimate. We will have even more time if we can slow down the progression. We won't suffocate, we will likely thrive, after we have a shaving of our population for a bit. Humans are smart. Heck, we might even get taller. Bring back the giant sloths and Titanoboa!

Is there a way we can capture the methane as it's coming through the perma frost and use it as a commodity? Maybe using it in a way that the gases given off of how we use it will not damage the atmosphere.
This is the biggest mistake we humans has done, trying to get intelligent than nature.
In some places, we have been using methane from land fills to power houses already. Let's just say it's not impossible.
possibly, but methane oxidises to create even more CO2 its extremely potent. To capture and use it in a way to not damage the atmosphere is impossible because you're going to be damaging the atmosphere. Unless you somehow capture all the methane that's seeping it out, harnessing it and capturing the CO2 it turns into and then storing that deep underground well in the bedrock of the Earth.
It's spread out over the entire arctic, there's no way you could capture all of it without blanketing it in equipment which is obviously unrealistic
The methane from the permafrost is all over the artic, I’m pretty sure folks already been mentioning that, and there’s forests and other lands sinking, it is too dangerous to start putting equipment to just extract the methane alone, and there’s tons of methane gases from the permafrost since the planet is continuing to rise and warm up, she will continue to grow while some of us will continue to deny the facts and try to cover things up until the planet decides when she wants her planet how she wants it.
