Technically we are still in the last Ice Age, until the poles are free if ice, we are still in it.
Changing the goal posts. Nice.
Interesting perspective
@@Encephalitisifynot really, it's a fact.
@@Encephalitisify For 90 percent of its existence, Earth was ice cap free. Greenland has ancient trees and elephant bones buried under the ice sheet. Antarctica once was cover in jungles. Earth today is much colder than normal.
@@revolutionaryhamburger there is so much missing from your comment, it would require an essay to give the details on why this simple statement is entirely deceptive.
The " temperate climate" that we enjoy today is not the " norm" but the exception!
Stone age man surviving an ice age is much more impressive than the space shuttle, tbh.
With the earth as insulation, living like Escomos just above freezing. Bbrrr...
A single-celled organism being able to crash the whole world's ecosystem sounds more familiar when you consider that single-celled organisms were the most complex life form on the planet at the time. The most complex life form on the planet still has the ability to crash the planet's ecosystem.
this is just a upload of a program called naked science. It’s specifically episode 7 of season 5 (available on Apple tv) “Snowball earth”.
Content theft isn't cool, but paywalling science content is worse. Some of us can't afford to pay to access content - and shouldn't have to pay for it ourselves when advertisers are so eager to shoulder that burden for us.
I would have thought it was a near certainty, the last ice age only ended about 10,000 years ago and it's cyclical
It generally is cyclical, but because of climate change that date has been put off several thousand years. Normally, from what can be ascertained, an interglacial has generally lasted 10,000-12,000 years.
Yeah.. basically a 10-15k yr cycle.. but the earth doesnt 'completely' freeze over in those times.. like 30% or more of the planet..
100% has only happened about two times in earths history.. (one of those lasting 15million yrs)..
The rapid acceleration since the 1970's is well beyond the natural scale., so if we're cant figure it out, then we might trigger another one of those snowball earth situations and there will be no safe zone for any human, or most of life as we know it, for potentially millions of years.
well that is because you were misinformed!
The cyclical ice ages are a separate cycle than the prior examples of a snowball Earth we're being asked to consider. The snowball (Or slushball if you prefer) were much rarer events, happening mayb as many as 3 times in the past history of the planet. 2.20 billion years ago in one example, 650 million years ago ini a subsequent example and
I did not hear mention of any time frame suggestion for the third snowball example. The more typical and less severe more typical ice age glaciations happen at roughly 80k - 100k year periods.
Environmental politics vs science vs people. What will the major plot points be when the climate moves stepwise towards burying everything above 40 degrees north under ice, and turns the corn and wheat belts into permafrost?
I guess youtube turned down the volume of this video by about -14db, could be a sign that some parts of the video were too loud, this video about an Ice age is very quiet. Unfortunately the ads still play at max volume.
Edit: -15.9db with the setting 'stable volume' turned off.
Google 'youtube revanced'.
If you're on iOS, there are other solutions but I'm not familiar, apparently there's something called 'sideload utilities', like "AltStore", and from there "youtube++" or "uYou+"

Of course there will be another ice age. The earth works in cycles. Besides a number of other reasons (volcanic eruption, meteor impact, etc.)
Straight to the comments .
Long story short..,
If it gets too hot too fast, then the Glaciers melt too fast.. if the Glaciers melt too fast then the Ocean cools too fast.. if the oceans cool too fast then the Gulf Stream and other currents shut down and everything freezes. The End.
Hopefully that will happen the day after tomorrow.
@@world_still_spinsI see what you did there.
Brrrrrrrr
i know were you have been last summer @@davidhughes6048

Can we finish up the ice age we are currently in before worrying about the next one lol?
"The ability to convert carbon dioxide into oxygen using the sun's energy" misses completely what plants actually do. They convert carbon dioxide and water into sugars, using the sun's energy, and then use these sugars to grow.
Oxygen is released by this process as a waste product. They're not trying to produce oxygen any more than a gold mining company is trying to produce tailings dams. It's just a waste product they're dumping in the ecosystem and hoping someone else will clean it up for them.
This isn't an argument for or against the snowball earth theory, but Professor Alan's argument against the theory is flawed. Wind isn't the only mechanism that would create ripple effects on the sea floor. Water currents also create ripples on the sea floor, and those are created by the Coriolas Effect and tides.
The title of this video will have people watching this wondering if we'll someday go back to Pleistocene conditions, but the content jumps immediately to snowball Earth which was a completely different time period and much more severe conditions with an ecology we don't have anymore. It's like watching a video with a title that say "Why Headaches Happen" and the first thing they talk about is a major skull fracture.
The middle doesn't freeze but the rain doesn't fall
My heater went out 2 weeks ago. Feels like ice age right now for me.
"it's unlikely that mankind will be around to witness another snowball Earth" That statement leaves a lot to ponder. Is the author saying that we are unlikely to survive or that we will all be living on other planets? Today, we have a much greater hope and need to be an interplanetary species. A million years is a long time for any species to survive. Yet, we are extraordinary creatures of intelligence and ingenuity. I believe we will survive for much longer.
Leonard Nimoy seems to think so on that show in search of.
Who knew all you had to do to be a science professor at Harvard was freeze rocks
Anyone that believes we could do any actual long term change to the climate from driving to work and heating the house needs to give their head a shake.
There's no way we'd be able to burn our way out of that one.
Wisconsin isn’t on that list (1:50) because we’re accustomed to this shit.
So would the ice reach the equator before the ocean levels drop so low the Gulf starts rebounding and becomes a frozen beach. Or would the ocean become ultra salty and not freeze?
Will the earth experience a ice age. Absolutely. Will we be around to see it? Maybe.
First great story
There are glaciers on the equator right now.
And the curie point, how is that affected?
Wheres the volume...?
Please, oh please, please, PLEEEEASE!!!❤️❤️❤️
Nice
We could control the temperature by floating material in the oceans. These floaters would be black on one side, and white on the other, and could be engineered to flip as needed. Hm.
We were warned that it was coming over 100 years ago!
I would like to witness the 2nd Ice-Age will happen where these details would happen for many years to come, for example, while we'll all make the best of everything:
1. Each and every last wrestling company and their Pay-Per-View shows, including the WWE (the World Wrestling Entertainment) and WrestleMania, would each end up with literal-zero fans in attendance, where it is like having the shows to each and every one of the fans
2. All animals, including the marine and mini ones, each had to be vaccinated with anti-freeze by many camouflaged-drones’ needleless syringes to avoid extinction and become adapted to the powerful second ice-age while being fed by veterinarians
3. Like the COVID-19, everybody had to be inside their homes and would order drinks and food online and then delivered, live-action movies and series, including Doctor Who, were to be released online early while others being filmed had changed to be winter-snow themed while many voice actors and actresses at films and series, Anime included, would still voice their respective characters from their homes, famous bands, musicians, singers, and rappers would perform at-home concerts
4. Every last freight and minor passenger trains, each with snowplows, were still in service while flights and cruises would be cancelled until Anti-Freeze will work on each vehicle
5. Schools, Colleges, Universities, Trials, Funerals, Weddings, etc. would instead take place online
6. Many outdoor live shows, including Dick Clark's New Rockin Eve, would be altered
Etc.
Pray to God we don't end up out off ice age, if that happens Earth would be 100% water.
lets goooo a new ice age! love those movies...
The theory I heard about snow ball earth is that there was a collapse in atmospheric CO2 levels due to blue green algae converting too much CO2 into oxygen and glucose.
There is plenty of science explaining the snowball earth ice ages. But whoever wrote this show couldn't be bothered finding out.
Lifes a cycle enjoy the ride❤️
All those brilliant scientists, and none of them thought to look past the boundaries of our little planet for contributing factors? They should have asked a solar scientist about the cycles the sun goes through over long time periods. They should have asked an astronomer about the possible changes exploding bolides and large impactors could have caused.
How can anybody predict the Ice Age could repeat on Earth not knowing what caused the Ice Age?
Tremendous presentation!! Thanks so much 😊
I'd like that fellow to look at the magnetic rock I found... it's weird.
Is it possible, sure. I still don't see enough evidence.
It takes thousands of years to have glaciers miles deep , it certainly wouldn't happen quickly.
Do we have evidence from more than one location for each episode? It's not inconceivable for ocean currents to carry icebergs along a particular path fast enough that they get to the equator before they melt if the world is in normal ice-age conditions - it doesn't need to be full snowball.
Also, the presence of dropstones in multiple layers kind of proves that the ice was routinely melting at this location - which is not full snowball anyway.
We need one. A lot of idiots could do with being frozen
@davidharkness9629 were in a cyclical, Rember this was a ball of fire cyclical Do you understand? surprised you stayed to the end did you?
Re: "Is There A Possibility Of A New Ice Age On Earth"?....It's an inevitability!
Do you think the last 5 or 6 were 'One Offs' FFS?
It's not if.. it's when
The Earth is in an Ice Age now and has been for at least 3 million years. What's coming up in the next maybe hundreds to a few thousand years is the start of the next glaciation cycle.
What did he name his kid?
Alnico?
Magneto
Geomagnetic pole shift trust me bro
Winter is coming !
To those at Spark, ice will be your least problem . You know what is coming.
There's no way we'd be able to burn our way out of that one if it happened.
Point of fact: The Earth is still in an ice age, we are simply at the height of an, "interglacial period." They never last more than 13k years or so...🥶
Had to be increased volcanism that caused those frozen CO2 deposits ,like the ones in the Atlantic off the Florida coast and the Arctic Ocean to release explosively. They would explode through thick ice easily.
It's not frozen Carbon Dioxide. It's frozen Methane. People are so stupid.
All a cycle. The carbon crowd acts like it’s something new and we should all be shocked. 😂
Most understand that, particularly the scientists who study it. What's new is emissions from human activity - not weather or climate. A species with a massive population that's literally reshaped the surface of the planet. But you don't need to be a scientist to understand that introducing new factors in a relatively closed system will have abnormal effects on the cycles in said system. Life in all its different evolutionary forms has been affecting systems on this rock for millions of years, for good and for bad. Those that didn't adapt died out. The planet doesn't need saving. You do, especially with that comfortable delusion you're living in.
He ain’t no scientician!
Love to se ourselves burn our way out of a snowball Earth.
You overestimate your ability to affect global cycles. If you cared, you would sell your private jet.
So, 44 minutes of why a 'snowball Earth' is going to wipe out life, finished off by a 10 - 20 second statement about how improbable the scenario actually is because the sun is hotter than ever before? Ha-ok
This was posted 7 days ago. The bacteria was in a battle. The first forms of life couldn’t photosynthesise then new forms of life that spread through the sea and changed could photosynthesis,they produced oxygen as waste. Oxygen was a killer to the old forms of life and so on and so on until the earth balanced out. In between all this it caused ice ages. I watched a documentary about how the first forms of life was in a battle and the gasses,oxygen ect. It was the atmosphere because of all the gasses and dying life forms that caused the ice ages. This has already been proven?
Do you mean one other than the ice age we are in currently?
Tards, the earth weather goes in cycles. So yes it can happen. The earth warms and cools. Why is this so surprising?
The world is in an ice age
Snowball earth sounds much like animal deaths after an asteroid impact. But here on earth we now have the flimsiest life you can think of. Birds. Theropods. Dinosaurs that could fly. But no pterosaurs. An older life form that had been evolving much longer. Didn't make it when it had a longer run so must have not been able to adapt like feathered critters did. In fact the feathers might be the answer. Ability to fly, ability to have warm clothing. Some factor doomed the pterosaurs, which might have been feathers.
New Ice Age...? no, New Head Age.. 😒
What is the current Co2 level in the earths atmosphere ? What is a normal Co2 level for the earth ? At what Co2 level does photosynthesis stop?
I don't believe that this whole planet was all ice. Nothing can change the temperature of the equator unless it becomes really far from the sun. That's why it's a theory, most likely never happened.
A second ice age. Great post apocalyptic survival video game setting
I'm sorry. But at 11:58 did that guy eat the bug that was crawling down into his mouth??? And not even skip a beat in that interview.
Yes.
It was delicious apparently.
I don’t think my 6 horse ariens will do me much good.Hey honey did it snow a lot last night?Ya about a quarter mile.
Actually the 800 pound impotent CO2 gorilla in the room is that no "expert" has a plausuble clue as to how an earth at 4000 ppm CO2 snowballed earth when bathed in normal solar radiation or how it at maximum albedo could have ever returned to life form friendly as today.
As an Australian, God i hope so.
As an Australian, she’ll be right mate.
@@glennllewellyn7369 have you seen our government lately?
@@mrgray5576
No. They left Australia 40 years ago.
Whatever you see now are hobgoblins and freakazoids.
It's all up to what the sun does.
Water makes CO2 at night. Makes o2 during the day.
We can not hear this video. Please resubmit it with an increased volume. Or, maybe the Utube police turned the volume down because it speaks the truth, contrary to the Global Warming discussion.
A global ice age can happen faster than you think. All that needs to happen is the core needs to change its direction. The Poles flipand the Earth begins to oscillate, changing the spin on the Earth and all of a sudden. The continents are no longer in the same orientation that they are either lined up along the equator or not. It's happening right now where the core is switching its direction
For decades I've seen animations of plate tech tonics moving continents around our globe BUT NEVER showing tidal fluctuating as well as crust appearing and disappearing on this vast liquid earth. Islands and continents rise and fall through our history BUT never mentioned or illustrated. C'mon now "scientist!". Something is missing!! Thx for healing me out.
Healing you out or hearing you out 😮? Yep, the whizzy graphics of continental drifting are dizzying but, as you say, somewhat incomplete as a representation of the full magmatic, mountain building and crust-fracturing, ocean floor expanding processes.
If a new ice age were to take place, it may well have been a result of a cooling of the Sun. Does our solar body experience cooler periods in their celestial life?
It has done, in recorded history. Whether it would be enough to outweigh our current carbon pollution is another question. Just think of all the lovely new coastal plains that would open up for agriculture if the sea level dropped a bit!
These scientists go on about carbon dioxide and methane warming the atmosphere but I hear nothing about air pressure. Has it decreased? During warmer periods millions of years ago atmospheric pressure may have been much higher and hence the temperatures. It hasn’t been discounted that the recent global warming has been caused by undersea volcanoes heating sea surface temperatures, water vapour and world temperatures.
We were supposed to be frozen in the 80's
Now
We're gonna burn up in 26 years
Honestly
We're still figuring this out and everyone wants to jump to conclusions
I don't make decisions about a planet thats been here billions of years when i only have 80 years on it at best.
I'm just livin what's left of my life man
We'll have to start prepping for this scenario right now, its clear that taking our foot of the co2 peddle will be disastrous for us. We need to start burning anything combustible preferably stuff with a high carbon content and pray were not to late.
What about global warming?😂😂😂
According to the Milankovitch (astronomical) Cycle Theory, another Ice Age is guaranteed. The problem is just when it will occur. The way human activity is messing up the planetary environment, that makes it harder to predict its arrival. Don't wait around for cooling, however, it is going to happen 50,000 years (or more) from now.
Hahahahaha humans messing up the planet’s atmosphere - how arrogant!
You DO know that the milankovitch cycle is 26,000 years.....right ??
One entire cycle happens every 26k years, so at the longest, it will be anout 13k years.
Misleading title. We are already in an ice-age. But this is about the much more extreme and rare snowball earth! Fortunately I only wasted 5 minutes...
Does atmosphere even matter?
And windmills and solar farms are over
Not such a bad thing , it might cool the temperature on political discourse 😂
If dark matter phase transition is a baseline temperature controller of every object with an internal gravitational barycenter then we can control the planets temperature by controlling the flow of dark matter to the planet
Would have loved to complety seen this, but you tube bombarded me with 11 commercials in 13 minutes, all done, bye bye
And humans how much CO2 does they produce..
What a silly question. Not only possible but inevitable. Silly hyoe video
The volcanos reversed everything bugger
Poles shifting only completely this time and of course it's still over a matter of time. But south pole will become North Pole and the north pole will become the south pole. Causing unspeakable devastation. As this type of pole shift has not happened before. But it's what I see happening. The north and south poles shifting in totality entirety.
They've happened before. They can happen as often as every 10 thousand years or so and as infrequently as every 50 million years or more. We can see evidence of magnetic polarity reversals by examining the geologic record. When lavas or sediments solidify, they often preserve a signature of the ambient magnetic field at the time of deposition.
@@sacredstarclairvoyantkat what's the evidence for your statement ?
@@HepCatJack I'm guessing you are unfamiliar with what clairvoyant is judging by this question to me. Visions are always subjective. It's important to know not everything is set in stone as there is free will which can change things.
@@sacredstarclairvoyantkat I'm familiar with how the observance of a phenomenon in quantum physics can somehow alter the phenomenon in the past. However I will take from your answer that you have no solid basis for claiming that the poles have never shifted in totality.
@@HepCatJack North and South Poles have shifted yes like normal but they haven't shifted in totality entirety of the physical north and south poles. I'm not sure how to write it so you can grasp or fully comprehend what I'm saying but this is my last attempt at it since it's a complete waste of my time trying to explain it to you. I usually just explain to the people who really want to know not some random person who may be one of those types of people that wants to be right all the time or strictly fact driven even though not everything in life is factual or science based knowledge. The key is " entirety ". The poles have never shifted in their entirety, but yes they have reversed and shifted as normal but not in their entirety. Have a good day.
Yes. The probability near 100%.... like wtf is going on with history these days?
Nature would have already have made this occur by now. Weather modification has been active for decades, with the first Military conflict involving such technology, taking place during the Vietnam era in the USA's history. Truth about Global Warming and mini Ice Age's occuring, relating to evidence from Milinkovic cycles, doesn't cater for the fact that our weather is artificially controlled and has been for a long time. Once it was started, it could not be rerurned to natural control, without devistating consequences.
Greta Thunberg disagrees! Marsha Marsha Marsha global warming warming warming
I’d love to watch all your docs however all that dramatic music and sound effects make it impossible. Please stop being so superficial. The topics are intriguing as they are already.
It will absolutely happen again. It’s how the earth cleanses itself. Look at pole reversal and micro move events.
Don’t attribute religious terms like “cleanse” to nature. Nature doesnt cleanse anything. Nature just is.
When will you yanks use the same terms of measurements as the rest of the world? -10 degrees what?
