The snowball Earth hypothesis is NOT now more accepted. There are major problems with it. One of which is "The snowball Earth hypothesis does not explain the alternation of glacial and interglacial events, nor the oscillation of glacial sheet margins."
I saw another documentary that said there was a snowball earth type situation going on 2.4-2.1 Billion years ago, also. So this was not the first time this had happened.
"could we survive if snowball Earth happened today" I think the biggest problem would be food security. Quite simply, there are no crops that grow in ice. You need to either import soil atop the ice or keep an area ice-free when it's cold enough outside at the equator that salt water will freeze. You need a way to stop a glacier in its tracks and prevent any ice or snow accumulation on farmland and remove any ice or snow that does fall. You also need crops that can grow in very cold environments like permafrost, or widespread greenhouses. I suspect the latter is more practical. So large scale production of greenhouse tents would likely be necessary. Enough to cover all arable land you wanted to save. You could irrigate by putting greenhouses with black interior over the ice itself and melting it inside a greenhouse tunnel, thus giving a supply of clean water for farming.
We would turn to hydroponics on a large scale. All vegetables would be grown indoors. The problem would be the animal food chain. We would have to find a way to feed other mammals, and creatures. Likely that we'd lose part of our food chain....?

I wonder if, when they calculate the historical location of the rock relevant to its magnetic density, they also consider the likelihood of the earth's magnetic poles being in a totally different location at that time? 🤔
Yup. And the surface was totally different, as was the atmosphere.....we cant comprehend it because we think of the Earth as it is now not as it was.....and we forget magnetism and the Suns' affect...
Pole flip plus shield loss could release the entire atmospheric layers and rapidly freeze the surface due to exposure to space .....locking the oxygen and hydrogen as ice......the planet would also have to be at its furthest point of orbit from the Sun....and therefore magnetically challenged by the distance...🤷♀️

Interesting how the notion of Catastrophism has become suddenly popular, whereas 100 years ago Evolution and Gradualism were the orthodoxy. Note that Australia's glacial past is suggested by 'continental drift' theory (now Tectonic Plate Theory) but periodic Pole Shifts might also account for that, and fit neatly within the idea of catastrophic and sudden changes to the planet which have a good deal of evidence to support them.
The physical poles don't shift, only the magnetic north and south pole do. Only plate tectonics and continental drift can explain the empirical evidence.

Whoaaaah there brother.....no matter how much the earth was frozen there would still be hundreds, possible thousands of volcanoes giving warmth and life to many, many animals. Also I suggest in all of that time, the land (plates) would be rising and sinking depending on the weight of the ice thickness. In other words...not all of the earth would be frozen at the one time. This series has facts that may be bent.

@Troll King yes they do. The magnetic fields left in rocks define it as such. Why do you suppose there are hippos, rhinos and wooly mammoths in Siberia found buried with vegetation in their stomachs buried beneath mud up against the sides of mountains? Also, satellite surveying of Siberia discovered kms of canels buried beneath the permafrost? What about the salt water mark on the sides of the giza pyramids, 2/3 rds up the face, that resemble a high tide mark at over 60 000 years old? Pole shifts have occurred, do occur and will continue to occur. What we, humanity, have, is the capacity to preserve this information for the future generations other than allowing, much less resigning ourselves, to allow others, such as the Vatican or the Freemasons to continue to withhold these records at the detriment of the future generations. As the ancients claimed, knowledge is wealth.
@Sarah Nyb same as these Africans claiming they built them I suppose? There is technology that is capable of reading how long a rock surface or face, has been exposed to sunlight.... didn't know? Guess at what length of time the giza pryamids have been exposed? Ohhh, and it's much much more accurate than carbon dating as well..... how about the pryamids in europe, and the balkans, or in china?

Why is it that the at the first mention of greenhouse gasses, the first one mentioned is CO2 - when water vapor is by far the most abundant greenhouse gas in our atmosphere, both in quantity and effectiveness…. 🤔
Probably a good thing they go to pretty remote locations and dig really deep. If you took a large amount of really old rocks with fossils from one location and time period and buried them in the correct time period but in a different location I bet you’d throw them off for a second or 2.
We are one but we are many and from all the lands on earth we come. we share a song and sing with one voice. I am,you are,. we're all just human's. This vid shows just how insignificant we all are and how important life really is.
Baseball hail, flooding, colder winters, heavy snow in deserts, all from the oceans being too warm in key areas like the N.Pacific where it brings rain in winter to Alaska and freezes oranges in Florida. The polar air now is flowing south only over land, a huge difference, the jetstream travels north, not east into N.America this amping heat gained in the Eastern Arctic, it's thawing everything pretty fast if you ask residents. CO2 is a most powerful gas regards climate for this planet and its biology.
@@DjGlenJon The sun sure does take part in "weather", for "climate" the tiny humans took over with 100ppm of CO2 in 100-years, the sun can't do that, eh? So, the carbon bomb is acidifying oceans 10x faster than extinction events with regard to aragonite, the sun can't do that. "The rate of acidification is 10-times faster or more than anything we have seen for the past 50-million years and perhaps over the last 300-million years.".

This is off topic, but there is _something_ about English accents that just demand my attention and make everything automatically more interesting. I wonder if the reverse effect happens in European countries? (American accents on documentaries instead?)
I don't know about the accent but I have read comments on multiple documentaries here that the American presentation style is a big turn-off for the continentally educated.
Too many "American accented" narrated documentaries sound to me like they were written for or by 12 year olds. Sorry, but I'm completely turned off by false, inappropriate inflection on the part of the narrator on serious subjects. JS.

Nevermind nuclear, you want to survive a modern snowball earth, coal. Burn enough, and everything gets covered in black soot. Good thing there's plenty of it.
I like that way of thinking. Dig in in a (old) coal mine which has still some reserves left. But if too many do it, wouldn't you also deplete the earth of oxygen? I guess you could tunnel out and grow some trees (heated by coal , they would love the CO2) but you would need to get the sunlight somehow down deep enough.
funny thing is that both sides are wrong, science disproves god and this video.if you fill an ice cube tray with water and put it in your freezer the ice that forms will fill the tray not the whole freezer. earth doesnt have enough water to cover all the land with ice

Dim Sun Snowball planets everywhere. Some planets just the right size for plate movements thus volcanos and co2 heating the air melting the ice. Perhaps we are rare in the cosmos.
I find Tony Robinson very easy to watch, but (of course there is a "but"), When there is a leap in evolution or the climate takes an unusual turn, I wish that he could find any other phrase to beginthe task of explaining things without first saying "Something remarkable happened..." Taken at its most basic, I hope it IS remarkable because you are remarking on it in this film
This is exactly why I don't get too concerned about global warming, when things go bad, it gets cold, not hot. Its been warmer and the seas have been higher just 120,000 years ago. Coal is the energy of the future.
I think you will find he is speaking that strange language borrowed by the Americans, English. And being a man of the theatre and BBC TV his command of the language is excellent.
Everyone is told that the earth is blue and beautiful, but the time when the earth is blue and beautiful is only about 500 million years out of 4.5 billion years.
The point of no return was the point at which the temperature of the atmosphere was sufficiently low enough to prevent global freezing and the growth of the ice sheets, and was not made in reference to the survival of living organisms. The presenter states this point quite clearly.
One obvious example of a dropstone, a.k.a. glacial erratic, would be a granite boulder in a layer of sandstone. You see, the granite is an igneous rock (that is: a rock that arises from the solidification of molten rock); and the sandstone is sedimentary.
39:15 "Volcanoes have another formidable weapon in their asshole"? I know it's arsenal...but listening to that real quick the first time was a very jarring and confusing moment.
The evolution of life seems to boil down a lot to that famous quip: If it wasn't for bad luck, I wouldn't have no luck at all. There may be planets that have such mild environments, for so long, that evolution never really goes anywhere, just staying in a perpetual state of goo.
Someone tell the people responsible for this video that the dominant green house gas is water vapor not carbon dioxide. At the end of the last ice age when the ice melted for whatever reason carbon dioxide levels started rising 800 to 1000 years after the melt started. The last ice age was very dry, all that water locked up in the ice cap, and very cold. The drought in Africa very nearly did for our species.
The position of extremophiles both of the cold and hot varieties could act as a barrier to extinction on the planet by jump starting viable lifeforms to an evolutionary path that would develop into complex lifeforms. If so, then introduction of those extremophiles to a planet like Mars might theoretically initiate life on that planet. If so, then cultures of these lifeforms may be the key to terraforming.
In my opinion, science and God are not mutually exclusive. The bible is a spiritual guidebook, not a science or history book. The people who wrote it were inspired by God, but their understanding was limited by the scientific knowledge of the time. I am a Christian but people who think there is no evolution, or that the Earth is 10,000 years old, are crazy.
A spiritual guide book? JESUS CHRIST use some logic. The bible is a tool to indoctrinate people into what is technically a fascist ideology that forbids existential thinking. An ideology designed to control the masses and is fueled by the number one predominant human trait "greed". @Advanced Cavemen It wouldn't hurt to use your brain before you hit the post button.
Well said Noneofyourbusiness!! Religion as a filter sure ruins what we are able to see, to try to understand. I totally agree and feel for those who don't know if God even wants them to entertain questioning his existence by watching science documentaries! Must be confusing.
Never mind the volumes of CO2, The thousands of cubic miles of ash ejected would cover the ice and absorb the radiant heat of the sun.. after the dust settled.
If volcanic eruptions reversed the snowball effect, why didn’t volcanic eruptions prevent it from happening in the first place? Seems like they would have kept things at a fluctuating balance rather than going to the extreme.
Before snowball: Volcanoes exist but cyanobacteria use more CO² than volcanoes produce. During snowball earth: Almost all cyanobacteria are dead. Volcanoes now produce more CO² than cyanobacteria use. CO²-content of the atmosphere slowly rises over millions of years, global warming happens, glaciers recede. It´s not that hard ffs
Oceans dropped by hundreds of feet as evaporated moisture remained largely locked up as ice on land. I don't believe there was ice 'miles deep' across the entire globe. I won't say all of earth wasn't below freezing, just not there was thick ice everywhere.
No, just posh English for glaciers... That is gla...ci...al ( 'a' as in clay, not 'a' as in apple). They do the same with grass, pronouncing it 'grarse' and 'barth' for bath, amongst many other words.
That’s how the English pronounce it. I do prefer the American pronunciation of glacier and I am English. We also say vitamins differently. I don’t like the way we say that either. It’s a bit like Tomato 🍅 Tomato 🍅
Single cell life occupied all the habitats, leaving little room for multicellular "experiments". Enter Snowball Earth, greatly reducing viable habitats, reducing the number of single cell life. As the earth recovers (from any great catastrophe), habitats open with minimal competition. Experiments are given a chance to develop superiority. As life fills all the habitats, life becomes (relatively) static again, requiring another catastrophe for the next big step. That is my story and I'm sticking to it....
Religion and science....both are curses to man kind at the moment. Everyone has to be "right". When in reality....both go hand in hand. Science is the breaking down and descriptive communication of the "magic" or creation like features of the universe and religion is the simplistic approach to give credit to a creator of life. We can't comprehend the truth of the universe....yet we try, with both science and religion.
We here in America say it the same way as everyone but the narrator in this video. We pronounce it "glay-see-er", which when said quickly becomes two syllables and sounds like "glay-sure". Really the only difference is the pronunciation of the A. The narrator says it like the A in "ass", while we pronounce it like the A in "day".
All the Ice on earth surface forms when the snow that falls on it, gets to be more and more and, doe to its own weight, it compresses itself into ice. So when the big freeze enveloped the whole planet it also froze the surface of the oceans and, in my humble view, that meant the end of cloud formation and precipitation all together. So where did those hundreds of meters thick equatorial ice sheets come from, just from residual air humidity? Or were they pushed towards the equator by the large weight of the whole northern and southern hemisphere, kilometre thick ice sheets? Just wondering how that was even possible. Is there anyone with an educated guess who could add light to this dilemma of mine? Thanks!
Snowball earth developed from glaciers moving below the 30 degree latitude tipping point. Thus glaciers formed in the north and south and moved towards the equator, creating the drop-stone formation the documentary talks about (which cannot be created by normal snow formation processes). The glaciers over land would have joined at the equator ahead of glaciers over sea (the supercontinent spanned the equator on one side of the planet, with ocean on the other side), and the sea glaciers may only have been narrowly preceded by sheet ice (how much sheet ice I don't know). Once the oceans were covered in ice, no more water vapour could cycle from the sea into the atmosphere, which created a limiting cap for humidity in the atmosphere, but global temperatures would also drop the closer the glaciation got to the equator (the reflectivity of all the ice over the earth's surface area would lower planetary retention of heat), so water vapour remaining in the atmospheric system that would not have frozen before would have done so now, adding to the ice sheets. And yeah, glaciers actually move, so the glacier creation starts far from the equator, where year-around snow builds up, and the increasing weight of snow layers on top of each other incites a process that transforms ice into a glacier state (driven by the pressure gradient). The glacier movement follows the temperature differential. Someone else here might give you more but if you want more information than the basic broad outline I've given here, I suggest looking up the topic ("glacier formation and movement" might be helpful depending on what you want to know).

@@channel1_channel because the hottest temperatures recorded have been in the past 5 years while we were in a solar minimum , heading towards a grand solar minimum. The whole globe should be cooling, not warming, if these cycles were the chief influence of climate change, and theyre not. Volcanic eruptions have cooler the earth more than solar minimums
@@markwestfall9410 "because the hottest temperatures recorded have been in the past 5 years" - I don't agree with this, but hey, our temperature records are so scant and over such a small timeframe (plus they are manipulated). Further, the poles are supposed to warm first. Last year was one of the coldest on record (if not the coldest) for Antarctica. Antarctic sea ice cover is higher on average over the last decade than it was around 30 years ago. It appears the climate is subject to numerous cycles, with sun spots and ocean cycles being of great importance. Let's not forget the Milankovitch cycles.
I have a couple of problems with some of their conclusions. One: They stated that the magnetic properties of those dropstones proved that those stones were deposed there by glaciers at or very near the equator. But earlier, they explained that those rocks got their magnetic qualities when they were formed. So in my way of thinking, the magnetic qualities of those rocks only showed that they were originally formed near the equator. That could have been two billion years before they were moved by the glacier. In that billion years, isn't it possible that piece of the earth's crust could have been in both of those places? Near the equator when those rocks were formed, then slowly but surely that same piece of land, a billion years later, is near one of the poles and covered with glaciers. I'm not saying that's what happened. I'm just saying that these scientists didn't sell their theory very convincingly this time.
+Edward bourgeois You may have it backwards. They were formed far from the equator and then carried toward the equator by the glaciers, I think. Also, the Tetonic plates did a lot of moving around. Land used to be all one continent and I think when it was, it was closer to the equator, but not sure of that.
I find it weird that the Earth was moving for millions, billions of years but those just laid there since glaciers moved them not affected by changes going on around them? wouldn't they erode? move to another place? get sucked into magma under plate tectonic and be destroyed?
@@wiezyczkowatayes. How about the theory that the rock landed there from being blown out of an erupting volcano or because of being ejected from a meteor impact. They didn't say they knew where the rock came from, just that it wouldn't get there by normal processes.

Note that Australia's glacial past is suggested by 'continental drift' theory (now Tectonic Plate Theory) but periodic Pole Shifts might also account for that, and fit neatly within the idea of catastrophic and sudden changes to the planet which have a good deal of evidence to support them.
The physical poles don't shift, only the magnetic north and south pole do. Only plate tectonics and continental drift can explain the empirical evidence.

Whoaaaah there brother.....no matter how much the earth was frozen there would still be hundreds, possible thousands of volcanoes giving warmth and life to many, many animals. Also I suggest in all of that time, the land (plates) would be rising and sinking depending on the weight of the ice thickness. In other words...not all of the earth would be frozen at the one time.

Solar minimums, red dwarfs with their own numerous moons, pole shifts both magnetic and physical......
@Troll King yes they do. The magnetic fields left in rocks define it as such. Why do you suppose there are hippos, rhinos and wooly mammoths in Siberia found buried with vegetation in their stomachs buried beneath mud up against the sides of mountains? Also, satellite surveying of Siberia discovered kms of canels buried beneath the permafrost? What about the salt water mark on the sides of the giza pyramids, 2/3 rds up the face, that resemble a high tide mark at over 60 000 years old? Pole shifts have occurred, do occur and will continue to occur. What we, humanity, have, is the capacity to preserve this information for the future generations other than allowing, much less resigning ourselves, to allow others, such as the Vatican or the Freemasons to continue to withhold these records at the detriment of the future generations. As the ancients claimed, knowledge is wealth.

I guess you could tunnel out and grow some trees (heated by coal , they would love the CO2) but you would need to get the sunlight somehow down deep enough.

That crazy Brit. Obviously, it wasn't the point of no return because he's sitting up there yapping.
The point of no return was the point at which the temperature of the atmosphere was sufficiently low enough to prevent global freezing and the growth of the ice sheets, and was not made in reference to the survival of living organisms. The presenter states this point quite clearly.
One obvious example of a dropstone, a.k.a. glacial erratic, would be a granite boulder in a layer of sandstone. You see, the granite is an igneous rock (that is: a rock that arises from the solidification of molten rock); and the sandstone is sedimentary.

The evolution of life seems to boil down a lot to that famous quip: If it wasn't for bad luck, I wouldn't have no luck at all.
There may be planets that have such mild environments, for so long, that evolution never really goes anywhere, just staying in a perpetual state of goo.
Someone tell the people responsible for this video that the dominant green house gas is water vapor not carbon dioxide. At the end of the last ice age when the ice melted for whatever reason carbon dioxide levels started rising 800 to 1000 years after the melt started. The last ice age was very dry, all that water locked up in the ice cap, and very cold. The drought in Africa very nearly did for our species.

The position of extremophiles both of the cold and hot varieties could act as a barrier to extinction on the planet by jump starting viable lifeforms to an evolutionary path that would develop into complex lifeforms. If so, then introduction of those extremophiles to a planet like Mars might theoretically initiate life on that planet. If so, then cultures of these lifeforms may be the key to terraforming.
An awesome idea that i've never read about and never heard about and never thought about before.

The history that science has built up of the earth is far more beautiful and awesome than anything in any 'holy' book.
The HOly Bible teaches atat even nature itself shows you God.
In my opinion, science and God are not mutually exclusive. The bible is a spiritual guidebook, not a science or history book. The people who wrote it were inspired by God, but their understanding was limited by the scientific knowledge of the time. I am a Christian but people who think there is no evolution, or that the Earth is 10,000 years old, are crazy.
A spiritual guide book? JESUS CHRIST use some logic. The bible is a tool to indoctrinate people into what is technically a fascist ideology that forbids existential thinking.

Never mind the volumes of CO2, The thousands of cubic miles of ash ejected would cover the ice and absorb the radiant heat of the sun.. after the dust settled.
If volcanic eruptions reversed the snowball effect, why didn’t volcanic eruptions prevent it from happening in the first place? Seems like they would have kept things at a fluctuating balance rather than going to the extreme.
Same thought went through my head. What, no volcanoes prior to 650 million ya? And for the entire 25 million years locked in the ice? Not buying that.
Before snowball: Volcanoes exist but cyanobacteria use more CO² than volcanoes produce.
During snowball earth: Almost all cyanobacteria are dead. Volcanoes now produce more CO² than cyanobacteria use. CO²-content of the atmosphere slowly rises over millions of years, global warming happens, glaciers recede.
It´s not that hard ffs
Where did ALL that water (ice) come from and where did it go? to cover the earth that thick?☔
Oceans dropped by hundreds of feet as evaporated moisture remained largely locked up as ice on land. I don't believe there was ice 'miles deep' across the entire globe. I won't say all of earth wasn't below freezing, just not there was thick ice everywhere.
Glassy-ers are British Glaciers, right?
No, just posh English for glaciers... That is gla...ci...al ( 'a' as in clay, not 'a' as in apple). They do the same with grass, pronouncing it 'grarse' and 'barth' for bath, amongst many other words.
Glassiar?!!!!!! Wow that's something new!!!!!!!?
That’s how the English pronounce it. I do prefer the American pronunciation of glacier and I am English. We also say vitamins differently. I don’t like the way we say that either. It’s a bit like Tomato 🍅 Tomato 🍅
Single cell life occupied all the habitats, leaving little room for multicellular "experiments". Enter Snowball Earth, greatly reducing viable habitats, reducing the number of single cell life.
As the earth recovers (from any great catastrophe), habitats open with minimal competition. Experiments are given a chance to develop superiority.
As life fills all the habitats, life becomes (relatively) static again, requiring another catastrophe for the next big step.
That is my story and I'm sticking to it....
Religion and science....both are curses to man kind at the moment. Everyone has to be "right". When in reality....both go hand in hand. Science is the breaking down and descriptive communication of the "magic" or creation like features of the universe and religion is the simplistic approach to give credit to a creator of life. We can't comprehend the truth of the universe....yet we try, with both science and religion.
Love the way he says glacier lol
If you sound it out, that’s how it’s pronounced.
how do you say it?
We here in America say it the same way as everyone but the narrator in this video. We pronounce it "glay-see-er", which when said quickly becomes two syllables and sounds like "glay-sure".
Really the only difference is the pronunciation of the A. The narrator says it like the A in "ass", while we pronounce it like the A in "day".
All the Ice on earth surface forms when the snow that falls on it, gets to be more and more and, doe to its own weight, it compresses itself into ice.
So when the big freeze enveloped the whole planet it also froze the surface of the oceans and, in my humble view, that meant the end of cloud formation and precipitation all together. So where did those hundreds of meters thick equatorial ice sheets come from, just from residual air humidity? Or were they pushed towards the equator by the large weight of the whole northern and southern hemisphere, kilometre thick ice sheets? Just wondering how that was even possible.
Is there anyone with an educated guess who could add light to this dilemma of mine? Thanks!
Snowball earth developed from glaciers moving below the 30 degree latitude tipping point. Thus glaciers formed in the north and south and moved towards the equator, creating the drop-stone formation the documentary talks about (which cannot be created by normal snow formation processes). The glaciers over land would have joined at the equator ahead of glaciers over sea (the supercontinent spanned the equator on one side of the planet, with ocean on the other side), and the sea glaciers may only have been narrowly preceded by sheet ice (how much sheet ice I don't know). Once the oceans were covered in ice, no more water vapour could cycle from the sea into the atmosphere, which created a limiting cap for humidity in the atmosphere, but global temperatures would also drop the closer the glaciation got to the equator (the reflectivity of all the ice over the earth's surface area would lower planetary retention of heat), so water vapour remaining in the atmospheric system that would not have frozen before would have done so now, adding to the ice sheets.
And yeah, glaciers actually move, so the glacier creation starts far from the equator, where year-around snow builds up, and the increasing weight of snow layers on top of each other incites a process that transforms ice into a glacier state (driven by the pressure gradient). The glacier movement follows the temperature differential.
Someone else here might give you more but if you want more information than the basic broad outline I've given here, I suggest looking up the topic ("glacier formation and movement" might be helpful depending on what you want to know).

@@markwestfall9410 "because the hottest temperatures recorded have been in the past 5 years" - I don't agree with this, but hey, our temperature records are so scant and over such a small timeframe (plus they are manipulated). Further, the poles are supposed to warm first. Last year was one of the coldest on record (if not the coldest) for Antarctica. Antarctic sea ice cover is higher on average over the last decade than it was around 30 years ago. It appears the climate is subject to numerous cycles, with sun spots and ocean cycles being of great importance. Let's not forget the Milankovitch cycles.
I have a couple of problems with some of their conclusions. One: They stated that the magnetic properties of those dropstones proved that those stones were deposed there by glaciers at or very near the equator. But earlier, they explained that those rocks got their magnetic qualities when they were formed. So in my way of thinking, the magnetic qualities of those rocks only showed that they were originally formed near the equator. That could have been two billion years before they were moved by the glacier. In that billion years, isn't it possible that piece of the earth's crust could have been in both of those places? Near the equator when those rocks were formed, then slowly but surely that same piece of land, a billion years later, is near one of the poles and covered with glaciers.
I'm not saying that's what happened. I'm just saying that these scientists didn't sell their theory very convincingly this time.
+Edward bourgeois You may have it backwards. They were formed far from the equator and then carried toward the equator by the glaciers, I think. Also, the Tetonic plates did a lot of moving around. Land used to be all one continent and I think when it was, it was closer to the equator, but not sure of that.
good point
I find it weird that the Earth was moving for millions, billions of years but those just laid there since glaciers moved them not affected by changes going on around them? wouldn't they erode? move to another place? get sucked into magma under plate tectonic and be destroyed?
@@wiezyczkowatayes. How about the theory that the rock landed there from being blown out of an erupting volcano or because of being ejected from a meteor impact. They didn't say they knew where the rock came from, just that it wouldn't get there by normal processes.
