4:04 “There’s estimated to be four times more carbon trapped in permafrost than all of the human-generated CO₂ emissions in modern history. The release into the atmosphere of even a fraction of this as carbon dioxide and methane will have a profound effect on the climate.”
The lede is buried exactly at the midpoint of the video.
I read a book maybe 15 yrs ago called Under a Green Sky. The author talked about what would happen if the permafrost melted and released all that methane. It was frightening then and more so now.
Nice positive-feedback loop we got there, let's do nothing at all to prevent it being kicked off :
@@danielmorris3687 Yes, and the release of “even a fraction” of the carbon dioxide and methane now locked up in the permafrost would help create a reinforcing feedback loop that then results in _even more_ carbon dioxide and methane being released into the atmosphere-which _could_ eventually result in “a pale green sky” that “has the smell of death and poison” and, even before that, a mass extinction event. That should frighten anybody.
_Edit:_ @isbestlizard I was drafting my comment as you were posting yours. Great minds…and ours, too.
#467 "There is no methane in permafrost because there is no carbon under the thin layer of tundra and thatch, only glacial flour, sand, gravel and ice lenses. Permafrost melts, every summer, then like Greenland snow and ice, _refreeze a month later._
Pioneering research done 20 years ago found no methane! "We hope this negative finding 'informs' arctic region climate research." DELIBERATE DISINFORMATION conflating *clathrates* (rare and deep ocean frozen methane,) with common permafrost tundra.
_How dare you!?_ Mil.Gov.Sci.Edu ministers once again trying to pad their '30-and-Out' pensions for life, stolen from Workers and their children!" Peter Torbay
@@paulhoughton1691 Yeah, we knew about the problem several decades ago, we should have taken it seriously and done something then. Even today, we act as if we've a lot of time to severely reduce human co2 emissions.
What happens? The methane stored will get out and make the climate change even worse because it's way worse than carbon dioxide.
Ahahahahaha, yep, ahahahahaha *continues clapping and laughing in despair and sadness* Oh I so wish humanity meets its end before reaching the stars, this race doesn't deserve a second chance!
Which will result in more permafrost thawing and thus even more methane being released. I think 'runaway' is an appropriate word😳
it's not the methane trapped in permafrost we should be worried about. it's the methane that's frozen on the sea floor
Yes methane hydrates is a planet killer
I'd be more worried about the (zombie) viruses that have been frozen for millions of years. If they get free we have no defense against them.
When I was in Svalbard a couple years ago. One day, it was so insanely hot I had to walk around in a T-shirt! I talked to a man who had lived up there for 40 years. He said it was the hottest day that early in the season he had ever seen in the 40 years he was up there.
It was shocking to see the ice shelf broken up into melting ice. Heartbreaking. (I also had to wear a T-shirt one day in Antarctica) Folks, this is very real.
People will watch this and a week later continue winging about how wind turbines aren't very nice to look at
A scab on the landscape
This should be taught in high schools!
You have to fund them, first.
It's taught in primary schools in the UK. What countries are not teaching it at that level?
Consumerism pays better.
They likely are teaching students to be community activists and complain about it rather than become scientists and solve the problems. Therefore, we are going to die.
... and then what happens? It's not lack of knowledge that results in dangers like this, it's the indifference/denial and outright opposition to knowledge that's the disease
Jesus Christ, the comments in this video make me root for global warming to wipe us all
We’re all going to die one day anyway.

Unfortunately the way how the world politics goes there probably will never be any meaningful changes to stop climate change until there are severe effects that is felt by a superpower nation/s
Dear cultists, CO2 is not a pollutant. It's the Gas of Life
@@JamesSmith-qs4hx In that case you would be full of life if you only breathed CO2. In biology everything is a poison it just depends on the dose.
Don't worry, after that they will try to elect fascists who will convince people there are simple easy solutions to this.
Only after THEN someone will be given power to do anything.
ln'dia is a 'super-power'. Sort of. Their solution to climate change is buy a tech visa and move to USA, where there is no climate crisis!
Yep bang on.
Then the north is permafucked, and the coast is permaflooded.
When permafrost thaws, it releases vast amounts of greenhouse gases like carbon dioxide and methane, exacerbating global warming and leading to a feedback loop of further thawing. This process can destabilize ecosystems, infrastructure, and communities in Arctic regions. The critical question is: How can we mitigate the impacts of permafrost thaw and prevent the acceleration of climate change?
Yes it will accelerate. Will take 5000 years instead of 10000 years. Why do you think Obama bought a house near the ocean and tells us we will die of rising oceans? Man open the eyes. The climate was and will be always changing, but it won't impact us at any rate. In 1970 they were telling Maldives will be under water by 2020, they are not. Oceans are rising 0.1mm (human hair thickness) per year.
@@GallAnonim-jx2cz You are misunderstanding acceleration. Oceans are rising at a very small rate at the moment. Over the next couple of decades it will be a small rate and next century it will be at a noticeable rate. The issue is not the ocean level, it is to do with the energy absorbed by the ocean and atmosphere. This energy makes the effects our weather much stronger. We will have more storms and of greater intensity, we will have more droughts and of greater intensity, we will have greater floods and of greater intensity.
What would take 10,000 years will now take 200-400 years. And no, no scientists were saying that the Maldives would be underwater by the 2020s.
@@trevx3680 the ice that remains is what remains from the last Ice Age. And life did perfectly fine before that, when there was no ice LOL
@@matthewbaker2573 You have no idea about life in earlier ages. We are on track to quickly reach 500ppm. The last time this happened terrestrial life collapsed and the marine life went through massive changes and ultimately new species adapted and flourished. The same collapse of terrestrial and upheaval of marine life happened when global temperatures sharply decreased during the ice ages.
Life did not do well.
Exponential melting. I wonder if we've reached or passed the tipping point yet.
We’ve passed it already. We’ll need to simultaneously reduce emissions and block incoming light to avoid further catastrophe.
I thought we have plot armour, but I'm not sure about this
'The Tipping Point' was a Wikkan book title about Salem. Try to keep up. Gore stole his '97%' I.T. movie jingle from Mazola Margarine: _"It's 97% Fat Free!_ See, Madison Avenue focus groups found '97%' was the magic number for full compliance. If Biden had claimed 97% of those who took the )ab would survive, he might have had compliance! Nancy's Existential Climate Crisis! used a Big Word. Existential. That's a no-no. _She should've said Climate Crisps!_
If July and August provide two more record global average temperatures then it's confirmed - phase shift
Which is likely chaos for decades or centuries until the perturbed system reaches a new equilibrium
@@AogNubJoshh Would a nuclear winter help? :\

Thank you for saying 'when' rather than the usual reticent 'if'...
What happens when that permanent frost becomes not permanent
It becomes part of the active layer, and eventually melts down, releasing trapped CO2, methane, and other organic materials.
The internationally-accepted lPCC prediction is '+1.8°C by 2100'. That's +0.04°C per year. For the math-challenged, it will be _1,000 years_ before Seattle is 'CLIMATE BOILING!' Delhi, yet 33,000,000 residents of Delhi are doing fine. 32°C today. It's Summer!
@@robertmarmaduke186 Nope. It is increasing exponentially. For those who don't understand exponential mathematics, it will be between 100-200 years. Well before that the changing climate patterns will result in multiple ecosystems collapsing (including where we get our food from).
This video is repost from one of other BBC channels. I actually want to give big thumbs up for this piece, it explains really well what permafrost is and why it will be dangerous when it thaws.
Right now, story with CO2 is very simple, we have to drastically cut everything down NOW if we want to be in hospitable hell. If not, we simply gonna die as species, along with others. There is no way for us to mass adapt to +7C for example. There are no physically possible solutions. it is that simple.
And that is if we take only temperature raise alone into account. If we ignore storms going nuts, destruction of plantations, food sources and chains. Mass migrations. Possible wars.
I should be numb but I am pretty convinced I know what I must do for rest of my life. It is easy choice to make. Also I know, majority of people trolling under such videos are not real people, actual denial is small, yet the political structures of Western countries are built to defend wealthy and rich. So as oil barons have massive war chests....it is simple choice, them or us.
Again, it is very easy to choose.

When it thaws, ice turns into water... Just like when anything else thaws.
There is a reason we are finding fossils as the permafrost melts. It's not because the animal died on the ice and sunk. It's because we are still in one of the coldest periods of Earths history. One day it may be too hot for humans to survive (just like it once was). We are temporary commuters on this rock.
Meanwhile, the BBC has plenty of time to shovel your gullet full of propaganda lies
Parasites on this rock* 😂
We are a plague of destruction.
The video is about some big changes, which we have caused in the last 150 years.
You're talking about changes that take thousands to millions of years, or a global natural disaster.
We are temporary residents of this rock, tha's right. But why? Look what we did with this rock. Within the last 150 years we created several reasons why we will only be here temporarily. We are industrially destroying the entire planet on various levels. We have already triggered the 6th measurable major species extinction in the history of the earth and some other global events that are otherwise only comparable to global natural disasters especially in such a short time.

If woody mammoths are found after permafrost thaws, doesn't it mean it was warmer when they were alive?
No. It means soil covered them and the bodies were frozen
The planet has heated and cooled many times before we came along.
Yeah, at an acceptable rate due to natural processes. Now it is doing so at a higher rate for anthropogenic reasons.

That's what happens when there is not enough CO2 in the air
and ecosystems collapse and eventually evolve. Life will continue in some form.

how did life survive when there was no ice on the planet before the last Ice Age ?

Our fate is sealed.
It’s permanent frost
No more ice-cream, main thing of concern.
it's getting hot in here, because we all got gas.
It's going whatever we do now.
That's the thing - the climate changes based on how much extra heat is in it, on how much carbon dioxide or methane and other greenhouse gases.
Those additional gases on top of a normal earth expectation without anthropogenic causes don't just disappear once in the atmosphere.
And the feedback loops?
Even if we stop all human emissions possible now, the damage is there for a very long time indeed.
I don't think anyone really knows what the future really holds, except adaptation.
great vid
Basically life itself will become the cause of the extinction of life. Normally the carbon would be in it's plain form, but because of this enormous amount of things that have lived and is carbon based, it will eventually end up as carbon based gases. The problematic thing here is that we've managed to speed up the process that would've otherwise taken millions of years
Go back to the Miocene and there was no permafrost at all. So there is no argument to say we need to keep permafrost alive.
Well, only if we humans still want to live here

When it comes to tipping points this is what the IPCC (Special Report on implications of 1.5C or more warming, Chapter 3) says:“there is little evidence for a tipping point in the transition from perennial to seasonal ice cover. No evidence has been found for irreversibility or tipping points, suggesting that year-round sea ice will return given a suitable climate”. The IPCC also do not believe the melting of the arctic permafrost will cause a tipping point in the release of warming methane gas “the carbon released to the atmosphere from thawing permafrost is projected to be restricted to 0.09-0.19 Gt C yr-1 at 2°C of global warming and to 0.08-0.16 Gt C yr-1 at 1.5°C, which does not indicate a tipping point”.
The Earth's climate is a multi input thermodynamic system and will conform to Le Chatelier's Principle.

By the time the IPCC publishes just about anything, the data is wrong and out of date.
The IPCC are famously underestimating the situation with overly conservative estimates and ignoring key tipping point data. They've been bought by oil money.

I thought it's about hawk thaws 🤔
All regions of the world are reliant upon one another, the economy and agriculture are at stake because our global ecosystems are at stake. Ecosystems have been delicately balanced through hundreds of years of gradual co-evolution. The way the climate is changing so rapidly these last couple of centuries does not allow for our plants, animals, fungi, and microbial communities to adapt fast enough, which is why an increasing number of biota are becoming extinct and endangered every passing year. Humans are animals too, we are smarter than all others but our survival is still entirely predicated on the health of the living organisms around us.

Very, very little information for the time spent.
It isn't real science reporting. The reporters go out to record human perspective/interest stories to fill up the work. It may well keep a large percentage of the viewership interested in watching, but in reality, this is entertainment, not a science show. They might think the entertainment padding allows them to educate people, but I think these type people aren't the type to be educated.
