- In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.
Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive sinkholes. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future.

If I didn't have any other channel than PBS, I would be happy! You learn, but it's never boring and that's a treasure! Blessings all!😃
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.
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.
@@jtlanden9771 And volcanos also put out more pollution than all of mankind's ambition.
@@scottashe984 pollution? Does this include noise, light, plastics, ... what kind of pollution?
@@scottashe984 -Wrong. Carbon dioxide created by humankind is over 100 times what volcanos emit. Check it out.
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?
Anywhere white goes, the place become a shithole soon.
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.
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. 🙄

Incredible documentary. Thank you PBS I've been watching since I was a little kid!
Yep and I love to listen to NPR in my car.
I think they have gotten so liberal it's not even worth defending anymore. They used to have the best woodworking, and hobby shows, and now it's gotten so political from the donors it's like watching Fox for liberals, and them believing everything they say. I still can relate to them better than conservative BS, but I'm not afraid to call a spade a spade
lol
This is just another scaremongering clip! It happened before, it will happen again and again......
I grew up on pbs, I enjoyed it so much and now it's why I enjoy documentaries!

Weird how we hate school and being educated as children…

Because you educated in school. You're force fed what they want you to learn. When you actually educate yourself and learn what you want it's liberating and fun.

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. ;)

This was a fantastic documentary
Hye, is it true that the sun doesn't rise from the same spot anymore? I'm just wondering 🤔
I've lived in North Carolina for 30 years, Virginia over 20 and it's very very clear to me that the climate has changed compared to years past. Heck I've seen a huge change here in va just over the past 5 to 10 years.

@@taradeviwest9351 Fair enough. However climate change can't alter the earth's orientation or axis.

Im not living in Alaska or in any place near that area but understanding this whole thing made me worry and sad about the future and the people living near that area.. I hope more people will/can watch this video to raise awareness. This is very informative and important, my kids are watching with me right now.. 🥺❤
Climate change has happened the moment the globe formed & cooled. It will continue to be different from one day to the next & we will Adapt. We cannot control the climate nor the giant nuclear reactor in the sky which is where our heat primarily comes from. It's the ebb & flow of life.As soon as there's an eruption those particles will filter the sun making a cooling effect. Antartica used to be lush & green the core samples show it. Stop worrying & live as the so called man made global warming scientists are corrupt- follow the money
I wouldn't worry too much about our current warming trend. We're really still just coming out of the little ice age that began in the 1300s. When interpreted by unbiased scientists, climate proxies from all over the world indicate the planet was actually 1 to 6 degrees C warmer than today during most of the last 10,000 years. It's the cold periods when humanity has suffered most from hunger, plagues, hurricanes, flooding, and extreme weather events.
Most people aren't aware that the thermal capture capability of atmospheric CO2 diminishes at a logarithmic scale, and at 420 PPM we're already well into the flattening part of the curve. Even if CO2 levels doubled the maximum effect would only be about another 1 to 2 degrees C of warming. Beyond that the warming effect of additional CO2 in the atmosphere would be virtually nil.
Increased CO2 levels do however have a very positive effect on plant life, which is why many commercial greenhouses use CO2 generators to pump the CO2 levels of their growing environments up to between 1000 and 1200 PPM. CO2 is the all in one fertilizer, food, and hydrator for plants. Think about it. When giant redwood and sequoias grow to be hundreds of feet tall, they don't suck up tons of soil, creating a huge pit in the ground. They're built from what they absorb through their leaves from the air, not the trace minerals they absorb through their roots.
Photosynthesis uses the sun's energy to convert CO2 and water into sugar and other hydrocarbons, releasing O2 as a byproduct. The higher the CO2 levels in the atmosphere the fewer stomata the plant requires to absorb the CO2 it depends on to live and grow. As such, the less water it loses during the process of gas exchange, making the plant more tolerant to drought. This is a big part of why the greening of the earth has been so visibly apparent over the last few decades in satellite images.
I watched PBS as a child as well always loved this channel !! A BIG THANKS for staying around til now, don't you go anywhere😉🤩👽❤💯💯

@@modernhaze3 that's really stretching the definition of propaganda. Everyone has a bias, and media generally has some point or idea behind it, but propaganda is a specific form of media. If I make a painting celebrating trees, that doesn't make it tree propaganda. Btw, I'm an actual person.
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.

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.
tell this to Klauss Schwab 😂

I've been known to release a trail of gas myself.😜😜😜😜

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.

@@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
Planet x
And he asked if he was smoking.
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.
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.
The end product from burning methane is Freindly.
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
Love this channel. It’s like how discovery channel used to be.
Now it is ran by a greedy CEO that loves to make cheap content.
I miss the old discovery channel
This entire channel is a propaganda mill to push the Climate change hoax.
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.
Very interesting program. The problems with thawing in towns might be solved by the same process that is 'geo-thermal' heating in 'the south'. In the far north, the process would be used to keep the ground frozen. With a new foundation the holes fore the coils are drilled and the hardware installed that allow a 12v 'fan' to circulate the air from 30ft down to the top 10ft. Insulate the top, and you might not even need any 'pylons' as the frozen slab would be 'stable' as is.
Having a 4ft space would be used as 'warm side' temps to a water tank and septic tanks could be located there, keeping them from freezing as well as making servicing easy.
In theory, you could also freeze the roads, but that might be expensive compared to the gains. What might work is laying some train tracks on the road and have everyone switch so that is used. The 'town' could have its own 'electric street car' that is on call 24/7. Towers used for transmission lines use small ground mounts, a few of those in a village would eliminate 'power poles' as well as allow for easy expansion.
Lakes in Canada and Russia could have a history that goes back to impacts a few billion years ago or as a sinkhole from that far back. That cone of dense material goes down to where magma is flowing under the crust. The Oceanic Crust map crust shows 40,000 miles of Oceanic Ridges that are spreading about the speed fingernails grow. Those outflows hug the bottom of the crust until they meet an outflow coming from the opposite direction. Both then begin to descend to replace the magma that is rising at the rifts.
The Pacific Blob is said to have a 60K year cycle, one that would see ice-ages come and go. Ice may seem to cool the land, but after there is a 'sheet' the ice begins to act like a blanket that inhibits heat from escaping. Over time, that allows the magma to 'heat up' to the extent that lakes of water can form on the ice of Greenland's Glaciers.
Areas that are melting can be aided by seeding the area by air with hemp. Air drops of 'chopped hemp' could also be done, as the goal is to fill up the void (road washout) with an insulating material that is also resistant to 'rotting'. Smaller blemished could have crews fo in when the hemp is mature and cut it and lay it in a pattern that compress into a 'mat'. Sidewalks in villages could be done the same way when going over areas that melt in the summer. Fabric in an existing road and then covered with a thin layer of gravel would prevent rutting and pot-holes, so would adapting travel by rail.
Thank you for this amazing Documentary. Most valuable and interesting.

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. 🤔
Whole lake swallowed up into a salt mine. Probably on plainly difficult channel
It's harder to preach about global warming in that case so they dont mention it
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.
Very nice awesome thank you for all you do and the recordings you put on they're beautiful keep up the good work😊
Its very interesting that native Alaskans have known about this for many years and this program presents it as a brand new mystery. And with the music building in the background as they list the amounts of change and the scary predictions they cause a panic.
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.

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.
100 % facts
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.

My undergrad is in environmental science and my immediate thought is how does this excess methane effecting the ground water and what would the large long term effect of that amount of methane leak be on the atmosphere 😳 this is as fascinating as it is frightening. Never heard of this before, loved learning about yet another mysterious wonder of earth 🥹🌎
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.
I think it's too late, we're in for a wild ride.
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.
Nah.... it's Aliens.

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?

Thanks a lot, the film is very educational!
is the sedge at ~22:50 still alive, then? i can't imagine chlorophyll remaining green for 20,000 years. But if it's still alive, how did it access sunlight? or does the cold preserve the chlorophyll cells in a way the larger animals just weren't? I would be super grateful if anyone in the comments knows more about this than me.
This is a really neat documentary. Definitely inspires me to learn and understand more about the world we live in.
I’ve had some planes that were killed by frost / ice damage. One turned a very dark green that almost looked like it would have been a very healthy leaf color, if not for the stem showing the truth. All that to say, the sedge is most likely dead but the color has been persevered in this similar way.
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.

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.
I love this one, what an interesting natural puzzle!
Went to have a look at the Yamal peninsula and wow, what a hole-covered area! I figured round shapes would stand out in the landscape, but not here. Can't imagine a wetter landscape over such a massive land area.
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.
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??????
They didn't mention that if polar ice melts, that decreases the earth's ability to reflect radiation from the sun back into space since that is what the ice does. That is an addition to the already alarming warning signs we are seeing.

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.
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

Scary documentary, but interesting and well presented.
sounds to me that we need to stop drilling oil from other places and start using up the methane that is in the permafrost instead, unless we find a way to keep it locked into the ground. but it sounds to me that we get a larger burst of uncontrolled methane that will return into co2 over the 12 years timespan. if we speed up that process while still a problem to get rid of the co2 we avoid the big spike we would otherwise experience. Not sure if there is a other way to manage the problem since i dont expect we can revert the melting from happening
There's no better documentary maker, than Nova/PBS. I've watched them for decades now, and it's always quality programming!
it ,s called nature,try watch something else then doomsday
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.
Key words: 'Watched for decades' and 'programming'

@@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.
@@brianbgood correct, the stalling of the jet stream is one of several dangerous tipping points.
This shows me that this is a natural phenomenon. Our earth goes through cycles and shifts through time. When you look at our earth through the idea of millions of years, it is not that startling.
I have an old Alaskan oddities book from the 1960's that details these things in South West Alaska. It explains that the think they could be fresh meteor impact sights though no evidence of meteoritic material is present.
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.

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.

those clouds are water vapor, that is how nuclear energy works, they use radioactive material to heat itself AND heat water so that the water vapor spins a turbine generator so we get electricity.
the clouds are not dangerous, the vapor is not dangerous, the water used to spin the turbine and that is leaving the giant towers are not in direct contact with the radioactive fuel, so there is no contamination, there is a separate water used to cool the nuclear reactor which is radiated and is taken care of safely and cleanly WHILE NOT RELEASING GREEN HOUSE GASSES IN ITS PROCESS.
only contamination produced from these power plants is the radiated material near the reactor which is very safely taken care of, extremely safely to be more accurate.

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.

Yet but don't mention a word of this to Faux news.
We don't want to distract them from relentlessly
pushing crypto currency to the Trump cult.
You have a layer of water flowing under the tundra. Gas in water heating up and the preasure of tundra on top. The gases have to exhaust in different place depending on the weak spot created by tundra melting...thins that area until,bumm..blows a hole in surface...
hahaha i loved the jump back and pause after the flame came up
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.
That doesn't make Elon musk any money fool, they would never.
Boy, or Girl, You really need to hear the rest of the story! You're being lied to!
@@Jayf1981 idk man I don't listen to what people tell me I formed that idea myself. They're very insistent on telling you it was caused by natural gas...that...is not what that looks like, at least to me. Looks like they were testing bombs dude you know Russia.
Edit: oh shoot my bad I thought this was my comment lol I've got the poo brain
@@4piecespicy589 You're putting spicy-petroleum chemical-waste in your body, what do you think poo is?
@@Jayf1981 the hell does that mean
Edit: it's been 20 minutes I still dont know why you talking about petroleum but ok. XD
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 remember that documentary. It really was a great one
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!
I love it
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.
Does the rate of melt per year relate to the age of that particular layer of permafrost?
