Every other Wednesday we present a new video, so join us to see the truth laid bare...
This spectacular five-part documentary series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence and suggesting that we are the product of catastrophe.
99% of all the creatures that have ever lived, no longer exist. They were wiped-out in a series of global catastrophes. Each disaster changed the course of evolution on earth. Without them mankind, nor any of the life we see around us, would be here today. For out of catastrophe comes rebirth. Evolution is a savage, imperfect and violent process. It's survive or perish. The earth's history of catastrophes has both moulded the planet and determined evolution. For each disaster led to another leap forward on the evolutionary trail form single celled bacteria to humankind itself.
Episode 2 - Snowball Earth
This programme delves into a world lying beneath a frozen surface. It is the greatest climate disaster ever to have hit Earth. 650 million years ago, a cataclysmic ice age sealed the entire planet beneath ice and snow, almost destroying life and turning the world into one huge snowball.
Snowball Earth uncovers the story behind one of the most controversial theories in science today. To investigate, the programme travels the world to follow scientists scouring southern Australia, Nevada's Death Valley and Alaskan glaciers for tantalising clues as to how our planet ran away into this doomsday scenario. The results could improve understanding of evolution and survival of life. - Наука та технологія
I don't know how they can talk about extremophiles surviving snowball Earth without discussing the deep sea geothermal activity. Vents and smokers on the sea floor give a rich mix of nutrients and warmth that do not require light for life to live and thrive. That's a big chunk they left out.
True. Another good documentary, Miracle Planet, explains just that and shows how thermophile bacteria live today in geothermal ponds in frozen parts of Iceland. Maybe there was life on shorelines too, where ice would break.
Theyre racist

He does it so nonchalantly, as if alone in a studio. I'd be paralyzingly self-conscious.

LOVE Tony Robinson! Watched him filming near Southwark Cathedral years ago. Used to love Time Team and when there was a pause in the filming I went up to him and said I didn’t want to interrupt but I just wanted to say a thank you for all the enjoyment he had given us over the years. He looked surprised and said ‘Thank You’ and as I walked away he said Thank You again!❤️
Glad to see that snowball earth is now more accepted. First learned about it in 2009. The Miracle Planet is another great documentary on it.
Watch GeoCosmic Rex with Randal Carlson
His earlier shows are the best. He talks about the North America’s ice melts and the way it shaped the landscape. His theories are very compiling.
@Larry Hillyer
Edit
That’s just 11,000-12,000 ago
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."
Why on earth does Tony makes it so easy to be appealing? I'm so excited Instumbled on this....I'd already binged every Time Team on the Tube

Thank you for posting these documentaries, at least for me it’s an escape from the day to day and I feel it’s important to know what we’ve come from and how lucky we are to be alive
Wow, I live right near the Flinders Ranges in the mid north of South Australia!! Love watching this series!!
Are you still living there 8 months later?
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....?
@messrsandersonco5985 in that situation no animal food supply,....plant indoor beans legumes,vegetables, fruit trees if possible, hope nothing rocks our boot 👋🚣♀️
Imagine being Charlton Heston as an astronaut coming back to earth in the future and it froze again...
I would have loved to have witnessed the monster tides travelling between 100-300 mph with wind speeds of 500 mph plus 😮
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? 🤔
I’m sure they take readings from other rocks in the surrounding area or continent and of the same age
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...🤷♀️
Yeah that's basic geology
They do infact it's these magnetic signitures which tell us the poles have changed position
nature is ultimate teacher for every one and every religion. it shows us and teaches us how to get repaired when intense pressure surround us.
IT'S SO FUNNY SEEING PEOPLE GET EXCITED OVER ICE,DIRT AND PLANTS!!!! ☺😊😀😃😁😄😂
Great work 🥳🥳🥳 Thank you 💜💜💜
This episode 2 - Snowball Earth reminds me of one of Jupiter's moons called - Europa.
Interesting and nice video, thanks.
@Ramboghini Balboni I agree with @86cleo86 i was thinking about the ice moon too there's no need to be such an ass about someone's comment
The new mission to 2 of Saturn’s moons, titan and esceledus (I spelled the second one wrong), will be leaving in a few years, huge chance there is more complex life on both of them, beyond, bacteria, Fido plankton, imagine civilization of octopus😂, the mission is called dragonfly, search it out

I lived in Death Valley over the winter once. While it is rather warm in the summer, freezing temperatures in the winter are not uncommon. In fact, I even went SNOW skiing in Death Valley.
It’s an AWSOME place
That’s deserts for you
A desert is, by definition, a place that receives less than 250 mm of precipitation annually. Actually, the world's largest desert is Antarctica.
there are rivers under the ice glaciers formed by the earths internal heat
There actually seems to be a riverine system under the ice in Antarctica that is larger than the Amazon system

Here watching the video. Love the quality!
Great video with beautiful nature
What an extremely informative history the lil green and bkue planet we call home!
its really good and presented in an accessible way - its action packed :)
Snowball Earth has happened many times in our past.
wrong fucktard ice-ages are not snowball earth that happened because of trees before termites and yeast could break them down!!!!!
Snowball earth is just happens every 4 to 3 times in the billion year.
@Lost In thoughts Which is serveral orders of magnitudes less than snowball earth...... Fucktard.
Only happened once cause the earth is flat and only once has the bottom side of the earth saw the sun once it flipped back over the earth warmed up and melted the ice.

Amazing how earth keeps changing and evolving.
Now we're helping to change it. Or so we're lend to believe
Almost like the earth goes through a cycle of life and unlife which as been ongoing since (possibly even before) Thea collided with Earth
"...a cunning plan!" Baldrick could figure out how to avoid a second snowball Earth, I'll bet.

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.
Greatness from humble beginnings.
Why would anyone dislike this video?
Possibly because they've just discovered that they're chumps compared to bacteria?
Because this video goes against the global warming narrative .
Most likely because they didn't watch it
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.
@Troll King Google itself ......
@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? How about the pryamids in australia covered in hieroglyphics....... yeah 5000 years old..... ?!? Riiight!!
😍 it’s just the thing I was looking for
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.
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.
Amazing

So ......... just curious ........ ? First, the study of the stones magnetism to discover where is came from is amazing! My question is how they account for pole reversals when studying the magnetism to determine origin. Wouldn't a pole reversal alter this drastically??
Dating of the apparent rock deposit. Which allows matching to known polarity changes. I believe.
great video by the way, riveting.

Awesome theories
Not theories but scientific facts.
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).

A mention of when a glacier melts away it looks like a bulldozer came through. I'm thinking it might also open up a world of discovery. Am I rightly thinking about the discoveries that may be found on such a terrain?
The Geologists have already beaten you to it.
Mostly rocks and sand. It does indeed bulldoze the landscapes. Went to the end of a glacier and gigantic rocks had been grinded to fine sand.
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.
Common in the Northeastern US and southern Canada along the Great Lakes.
"Ice thousands of meters thick" - Hey buddy where did you get all that water? All the oceans and moisture in the air just ain't enough to do the trick. 😛
Bacteria would be able to survive near hydro-thermal vents on the ocean floor as well.

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
it comes in second to "...some people think..."
some people think they have seen Elvis
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 🍅
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.
the sun controls our climate. the elietes just say its this n that to tax people
@@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.".

In areas of Australia has ice and snow like blue mountain NSW. And in the cool area where tiger snakes lived. To be honest that everywhere in Australia is temporated in south east. Tasmania is not that hot due to its climate the way it is.
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.
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".

Your mom
I know about Snowball Earth thanks to the History of Earth documentary
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.
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.
A fantastic comedy. Thanks heaps.
Happy Halloween
We still have an ice age in northern Alberta, Canada.
I have a question: where did so much ice come from, hundreds of meters thick covering the areas of the equator, when the evaporation of water from the oceans was stopped?
I was thinking the same thing, but it dawned on me, that the oceans froze to a very deep extent, more land exposed, more snow from evaporation of shallower seas, water expands when frozen also,
Even ice evaporates. Put ice trays in your freezer. Check the ice cubes every few months and you will notice them shrinking.
the ocean, as the ice freezes it expands and separates the salt, the salt then pushes down below, the expanding ice then just starts travelling being pushed along through new ice forming, expanding and pushing along the last one which can explain how boulders got up on mountain ranges and hilly areas, in reality we don't know exactly which ice age dropped what stone when because ice is the perfect criminal, it disappears without questioning.
If this planet was ever pushed out of the orbit as a thought, then it would freeze over into a ball of ice and by the time that we get out as far as Voyager is, the oxygen would start to rain.
Great question and very mysterious, just like the unknown origins of earths fresh water and salt water oceans.
Imagine how shallow the oceans must have been having kilometers thick ice covering the entire planet. I don't buy that the earth was covered with ice for 25 million years. Perhaps the land mass was covered to a great extent, but I have reservations about the entire ocean and equator area being cover, even for a short period of time. A completely frozen earth for 25 million years would have frozen all of the water in the ocean down to its floor. Subsequently, a thaw from such a horrific event would have scoured and forced a runoff of all of the land into the ocean. There would be no land mass remaining, just a deep ocean. They also say that these mega glaciations happened several times since 1 billion years ago. Land mass is fragile and easily broken down to silt and ash. To think that it could withstand even one full glaciation of kilometers thick ice seems in the realm of fairytale time to me.
Much of life today is still slime. Some of it with two legs.
starting right at the top, politicians/lawyers for who systemic & systematic "slime" is just a way of life.

Interesting facts about congratulations mrNelson1963
what about underground ? , but we'd need oil or petroleum products to keep our heat generators up and running or is this what is meant by "for a short time"
4 and a half billion YEARS later, along comes Tony ROBINSON, !

Of course all these ideas will evolve, as we learn more.
It is a miracle we Are here today, to argue bitterly over abstractions.

Makes you think how fortunate we are to be here with all that's gone on.
If even one thing had been different we would not be here.
This is why such fantastic documentaries as this are so important.
Maybe - just maybe - the more that humans realise just how fortunate we, and all other species that share the planet with us are to be here, the better we'll be to the planet, its environments and to all our fellow 'Earthlings'.
Unfortunately $$$$$$$$ puts a stop to that every time! 😪
@@iraceruk Good grief. Fact, you shop for best value, and more often than not that means $$$$ to you. Fact, you do not limit your CO2 footprint all you can. Self-righteous such as yourselves mean nothing to Mother Nature. Man is along for the ride.
I like the theory of reflection better than cyclic energy output of the sun, it makes more sense.
Imagine see a thousands of feet thick, thousands of feet tall & heavy as hell giant wall of ice slowly coming toward you & nothing that you can do to stop it?!?!
Anyone ever thought how much we can mess with geologists if we got random rocks and buried them in random parts of the earth?
🤣🤣🤣👍
thats such a "Rick" thing to say lol
@Carol Young it was a joke 🤦
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.
That was already done. Pyramids
Ten different programs, ten different theories.
Could be worse. Two economists three different opinions. Or is that lawyers?
Nitpicking question: if we're looking only to cover the surface entirely, then this scenario's fine; if we're looking more specifically for "thousands of meters of ice", it seems to fall somewhat short -- what am I missing? Total area = A (currently dry ~0.29, currently oceanic ~0.71); in order to cover the currently dry area with ice from oceanic water, we'd need to move ~0.41 of the current oceanic volume. With a current average oceanic depth of ~3.5 km, we'd get an Earth-area sheet of ice (even assuming all water to have frozen) of ~1.5 km.
Have a look at this It could explain where the water etc.. went. even if its not accurate it's an interesting watch
@@willdeit6057, I don't see a URL -- was there supposed to be one there?
nice
Surely life would have survived around hydrothermal vents.
That is why we have 2 eco systems on our planet.
actual life might have came from the vents

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.
