This didn’t make clear the full risk of methane, which is 80X stronger than CO2, has a much faster impact (tho tappers off in some decades). There is also even more stored in the ocean that is also thawing. As for hope, stopping climate change… there simply is none. CO2 emissions we have added will last centuries, and more tipping points, such as increased forest fires, loss of ice just adds more heat, more carbon… more heat… and more carbon. We have sealed the fate for the planet.
Did you not take grade 9 physics in the 70s. We filled a sealed bell jare with Methain and are and set it in the sunlight. In 30 minutes, it was full of CO2 and water vapor. I spent 43 years in factory maintenance and over saw the installation of many huge gasoline installations. When we did a high-pressure line purge, we had to have our supplier shut off all the pilot lights in a 2 mile radious. It had to be a sunny day. Then, they would open the line until it was discharging 90 pure methane. We tested the surrounding are and in half an hour, and when the LEL was below 5 percent, they would relight all of the pilot lights.we are talking many times the methain that all of the world permafrost melting would put out per day.
I live in the northern end of the Marseilles shale. If I put an opaque bucket upside down in my backyard, the air inside will alarm the 10 percent methane lel in 2 hours. The Arctic is less than a fart in a hurricane!
Utter nonsense. Have you heard of the Holocene Thermal Optimum? This was 5000-7000 years ago, when most of the permafrost in the Northern Hemisphere had melted, and the arctic Ocean was normally ice-free in Summer. Baffin Island was forested. Did this result in catastrophe?
Not for the planet but for humans.
@@terenceiutzi4003 SO you work for oil/gas industry. Got it.
Throughout planetary history extinction events have always been good things except for the victims.
Humans need to go so the planet can recover from the damage we’ve done.
What about the 450+ nuclear power plants?
bear in mind that all of this has happened to allow a very few people to become obscenely wealthy.
change that capitalist paradigm, and then maybe the outcome won't be so dire.
Money cannot be eaten.
@@ThibauddeLaMarnierre it'll take a while for that to sink in.
since for the last century and a half,
we have been told it can solve allll our problems.
uh, no its happened because we have overpopulated this planet.
All the hope in the world isn't going to stop what's already set-in.🥵💀😿
Is it too late?
Yes.
But there's still hope, right?
@@A3Kr0n Well.....
When the permafrost thaws, we boil to death. Simple.
It has happened dozens of times in the geologically recent past.
I guess it's a good thing that we only have about 30 to 50 years of fossil fuel resources left at our current level of usage. Just imagine, we might be taking holidays to the tropics( rain forrest ) of Antarctica soon.
Anyone seen the documentary about the Russian dude who wants to save the permafrost through the reintroduction of massive herds of bison and reindeer and the like? Crazy dude but some interesting ideas.
Jessie lives where I was born. My parents told stories about leaving the Arctic in a prop plane where they had to build bonfires under the engines to get them warm enough to turn over. -60C wasn't uncommon then.
Wow! 😮 Many thanks for watching
Permafrost loss seems like *the* climate time bomb considering the effects of its methane release.
Permafrost has melted many times in the past (most recently during the Holocene) without problems.
@@romanpolanski4928 oh good 👍
Good luck teaching common sense to the rest of humanity.
A giant fart will replace the Polar Vortex.
This important production I found on you tube, but what about NRK?
Loss of permafrost is a self feeding system. The more that melts the warmer it becomes and the more thaw. If no other factors were in place I think it would balance things out. However mitigation is not taking place place and the process will only accelerate.
The permafrost has melted and reformed dozens of times in the Quaternary Era. When has this resulted in catastrophe?
Cold is hitting Finland, currently!
O permafrost é um pedaco do bioma polar. Uma peca do quebra cabeca do dominio da agua na terra. Um pedaco da tecnologia da continuidade da vida . Fazer isso virar um reino inteligente e cheio de vidas e especies não é nada fácil. Sera necessario mexer nas geleiras e mudar cursos de aguas e ventos . E alterar o sistema de aquecimento fotonico e geotermico natural . Um trabalho genial. E cheio de muitas ideias .
Vcs vivem num lugar que era parte disso na Terra.
Alas, it’s too late to change or plan or adapt. We’re all responsible for this - even the people most affected by disappearing permafrost, as they live in propane-heated houses and ride around in pickups and snowmobiles while dressed in synthetic clothing. In my lifetime, I’m 65, the world’s climate has changed dramatically for everyone, though it’s more noticeable if you live in an area of permafrost, semi-desert, or a low-lying island or equatorial coastline. Those us in semi-prosperous North America might be fine for a while longer…at least until those in the South, about for and a half billion of them, need to move North to survive. I don’t expect it’s going to be very pretty.
we have about 3-5 years left so go home be with family 😢 !¡!!
Every time they say 2050, I laugh, sadly knowing it can’t
Fam is dysfunctional
we are so royally screwed. at least i will get to see how humanity ends.

So, do you have any perfect solutions to that? You say climate change, emissions, but people will not and cannot give up on the current life style ever. Permafrost thawing is a natural process of earth which is trying to recover damage ravaged by humans. Do you want to stop carbon emissions? Then, you must not use any fossil fuel-powered transportation and food that is cultivated and grown with fertilizers made of carbon resources.
Lifestyle change for everyone or get rid of a few billion of the problems. Which will the elites choose for the world?
Civilization Collapse will end that lifestyle.
Methane apocalypse.
If permafrost thaws then it was never permafrost. 🤯
Semi frost
The frost formerly known as perma.
Soft serve 🍦
Well it will have that effect on the climate. We aren't at glacial minimum yet, this effect happens through all the cycles of glacial maximum to minimum. The Scandinavian peninsulars are still rising from being pushed down into the mantle by the weight of ice at glacial maximum. The planet has never had 8 billion people that will be effected by this. Time to plan... Just as the people living on what is now the Dogger Bank under the North Sea and where the Black Sea is had to move after the great melt at the start of this cycle. Is mankind adding to the speed that we reach glacial minimum? Probably, but we need to plan changes in where we live and where we grow crops whatever carbon catching tech we have and even if we reduce carbon emissions to zero. Mother Earth has seen this all before, she will be fine but mankind needs to plan and start by reducing pollution and the rapid destruction of biodiversity and the Oceans. Time to clean up and adapt.

"We need to"
WE'RE NOT GONNA.
We're not going to do any of what you suggest. Even if America did, China and the rest of the globe is not going to.
Environmentalists are in denial about this fact, even if their predictions were right. But if they were right then where is "ice free Arctic by 2020"?
People who are in their twenties today do not remember 1998. Or 2006.
There are all kinds of predictions just as breathless as this one. It didn't happen the way it was forecast.
Human-induced climate change is happening 10 times faster than any thermal excursion in the geologic record, with second place being the PETM, the Paleocene-Eocene Thermal Maximum (which incidentally took hundreds of thousands of years to stabilize).
The trophic cascades will likely cause a mass extinction, maybe even bigger than the Permian/Triassic, which wiped out as much as 95% of all the Earth's land species-also caused primarily by climate change due to volcanic eruptions.
The Human makes a Problem with a Psychosis Visible and that makes it Visible ,that there not a big Cance Visible is .
Humans are the passive helpless victims then!!! If only humans were intelligent!
Their is a Pole Shift Happening, What do you Think that's doing to the Earth??
tell me
If you're talking about the rotational axis, that's impossible without drastically changing the angular momentum of the entire planet. If you're talking about the magnetic pole shifting, that's nothing new-it's been moving all around for millions of years without any major catastrophes.
If there is a "pole shift" happening (and as a geologist, I've been reading the science on the matter since my textbooks in the early 1980s and throughout my education and career), then the climate zones will be shifting to "nominal" north over one range of longitudes. And moving to the nominal "south" on the opposite set of longitudes.
So, which parts of the Earth's surface are getting colder due to your putative "pole shift"?

Do the Research Yourselves plenty of information on this site plenty of videos, published materials to prove what's Really going on, and if you can't see it that's not my fault, it's up to you use your own discernment...🙏♥️💯
Blessings, Love, Peace, & Light
@@tractmcglynn3587 So you don't understand what you're proposing well enough to explain it yourself.
That's a fail, in any exam.
Latest dose of fear porn from the global warming enthusiasts. Reality is not nearly so exciting. Guess what. Permafrost refreezes every Fall.
Who is this video made for? Who are you trying to reach?
The intended audience must be composed of credulous fools who know nothing about Climatology or Geology.
anyone willing to listen
@@SpeedyCorky naaahhh - needs to be more specific than that. to have value
The earth is not wounded. It will be just fine after we are gone.
Very simple thing that can be done over night to cut auto emissions in half is federally reduce the speed limit to 50mph and ground non emergency air travel. Neither of these things will change any ones life.
Stop all the talk and complaining and actually DO something.
