Catastrophe - Episode 2 - Snowball Earth

[@brylcreemy]

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.

[@petersmythe6462]

"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.

[@messrsandersonco5985]

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....?

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.

[@carloammann6127]

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!

[@13minutestomidnight]

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).

[@lawneymalbrough4309]

Even ice evaporates. Put ice trays in your freezer. Check the ice cubes every few months and you will notice them shrinking.

[@SkashTheKitsune]

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.

[@michaelbruns449]

Great question and very mysterious, just like the unknown origins of earths fresh water and salt water oceans.

[@PopsMdub]

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.

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.

[@edwardbourgeois1965]

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.

[@govindagovindaji4662]

+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.

[@robertplatte5700]

good point

[@wiezyczkowata]

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?

[@PopsMdub]

​@@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.

@@Mossyz. ​ @Mossyz Channel I'm amused by his opinion...but it begins to fall apart right out of the gate; the Earth isn't *ON* any place. It's travelling through a whole lot of places (likely all of which form an elliptical orbit around the sun). There have been *SEVERAL* glaciations/"ice ages..." What's the association with ice-age and being a moon of Jupiter anyway? Is that because our moon happens to be a cold, barren wasteland? So if Earth was a cold barren wasteland, it could be mistaken for a moon? And Jupiter's because, well, the Sun notwithstanding, everything in our solar system is under the influence of the Jovian Beast (it accounts for some obscenely large proportion of the matter in our solar system, *again, THE SUN NOTWITHSTANDING* At least one of Jupiter's moons (Io I think) is thought to be earth-like, but that's the inverse association; Earth's lush greenery subsumed into whatever you think Jupiter's moons might be like, as opposed to Earth's barren frigidity supplanted out into Jupiter's orbit, cuz, reasons.... I don't understand the need for the fanciful tale. Consider: at some point in time, the earth was a hellish ball of rock and fire, under continuous bombardment from asteroids and planetesimals for a billion years or so, when, seemingly out of nowhere, Theia, a planet roughly the size of Mars, collided with the earth in such a terrifyingly cataclysmic impact that a piece of it broke off and became our moon, while the rest of it was subsumed into the hellish inferno that would "soon" show the first signs of intelligent life. Why the fairy tales? I mean, I can appreciate the value of imagination, but if the original poster went looking for what they could learn about awesome astronomical events, or catasclysmic planet formation or whatever, then they could have come across not only the little tidbit about Theia and our moon, but all kinds of other cool things like what *spaghettification* means and what a white hole is and why combustion engines don't work in space and who knows what else.... It just strikes me as a more productive use of one's cognitive skills to get lost in the stupefying magic that is the real world (I couldn't resist that punny juxtaposition; *DON'T JUDGE ME!!) live well

@@OoogaBoog There is evidence of a global iridium layer in clay dating precisely from the Permian K-T boundary, a global carbon layer also indicates a mass extinction event;; otherwise, Iridium is only found in extra-terrestrial bodies (asteroids). The assumption is that Iridium may exist in greater amount below earth's crust, nearer the core. But it is otherwise non-existant upon the Earth apart from the known extra-terrestrial depositions. In practical terms, Iridium is more abundant in the asteroid belt it is that rare. A massive force is required to disperse Iridium globally like the Permian K-T boundary layer: 1) it is the most corrosion resistant metal in the table of the Elements 2) it is the 2nd most densest metal of all the elements 3) It has a melting point of 2,446C, and a boiling point of 4,130C.

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....
