  • so why are we trying to "prevent" global warming?

  • Hm it was in 2008 not in 2011 now we will have a burning world

  • If humans thousands of years ago survived this we're well able to do so for another one.

  • Narrator : What will happen when the world is frozen over?!

    Uhh the government goes into their underground eco system and we all die ?

  • Aussie Aussie Aussie... Oi Oi Oi !!!

  • What do you think will happen snowball earth or lava field earth? :O

  • lets do it.

  • ...Trapped in an ICY HELL. .. Lol!

  • '' walking in a winter wounderland'' Oh what Thumb Me Up Dudes If You Think You Are Cool :)

  • atleast africa would finally get some water...

  • while everyone is declaring these emergencies, us Canadians will be figuring out a way to dig realy deep ice holes... dicks

  • @KulakxFilms I KNOW MAN, SOME NONSENSE CANADIAN HATERRS. 'Least we canadians will get some fish!

  • did humans do this as well?

    

  • This is untenable. Anyone with slightest sense of logic and knowledge of geology would instantly know that a so called "snowball earth" could have never happened. The carbon dioxide cycles would have and will prevent any such event. As the water surfaces freeze and land is covered in snow, they stop absorbing CO2, which then accumulates in the atmosphere, warming up the globe and reversing the freeze. So where did all the CO2 and SO2 go if earth is totally frozen over? INTO the atmospher..

  • I blame Canada, that is where the cold comes from.

  • snowball earth?? Isn't it called an Ice Age...

  • @Maisy2499 snowball earth is basically an ice age, but the difference is that the whole world is covered in snow and ice (literally!)

  • @Mrcryptidsarereal O I C. Thats scary :S

  • Comment removed

  • @hotboyclarence this is a valid point. But then how do you explain the presence of dropstones deposited at the same time at the equator (proved by Joe Kershvink (spelling?) and his paleomagnetic experiments?). Or perhaps the cap carbonate rocks that are deposited directly and conformably above the dropstones indicating a rapid change in environment (i.e. snowball to no snowball) caused by a build up CO2 from volcanic activity? The snowball earth is such an interesting debate :)

  • @Fredholt56 Thanks for being civil instead of caling me names (as others do). A vast glaciation at the south pole (that is where the continents had presumable bunched, steteching to lower latitudes, would have brought LAND glaciers much closer to the equator in the SOUTHERN hemispher. Stronger ocean currents caused by much stronger winds (the difference of temperature between warm seas and glaciated land being the cause), would have carried rockladden icebergs closer to or at the equator....

  • Respond to this video... This would then allow for "dropstones" to be deposited near or occaionally at, the equator, carried in huge icebergs, calved by the land galciers (already closer to the equator), and pushed into the lower latitudes by stronger ocean currents circling the southern supercontinent. If the this southern supercontinent was also mountainous, the glaciers could have stretched directly into under the equator itself (as do today in Kenya and the Andes).....

  • Respond to this video... Then having icebergs floating into the equatorial waters carrying dropstones would be a routine. The warm water deposits would then alternate with the glaciers dropstone at the equator.

  • @hotboyclarence I completely understand your point and i can genuienly see no flaw in your argument! The only thing im still unsure about is the mathematical work of budyko where he proved that as glaciers moved closer to the equator (whether they be land ones or not) we enter a vicious circle of positive feedback whereas the earths albedo increases and thus so the earth cools more and more ice covers the earth. Once we enter this then we will be in a snowball earth surely? This theory is...

  • @Fredholt56 His calculations are not wrong in their numbers on in their premises. For the "point of no return" he supposes a precondition that IF it occurred (which did not and could not happen). We know that the continents were all bunched up in the southern hemisphere and were presumably glaciated. Fine. What makes them think the the norther hemisphere--being all ocean and easy heat transfer mechanism (ocean currents) also froze? The "threshold" could not be reached because......

  • ...theory is truly fascinating and your i value input alot as i am actually doing a project on the theory to go towards a university application this year!

  • @Fredholt56 because the northern hemisphere remained liquid (water). The Southern continents with a lot of high mountains (if they had just collided to form a super continent, then they must have had many many mountain ranges at the point of collision) could have been full or almost fully glaciated, that that would be only about 30% of the earth surface (actually less, realizing that 600 million years ago, there was less continental crust than it is today--it is continuously increasing....

  • @Fredholt56 So, with only 20-30% of earth being land, and the glaciation being primarily land phenomemon, and primarily just in the southern hemisphere, that threshold "point of no return" was never reached.

    BUT, even if that threshold were reached (no matter how unlikely) and the earth completely froze over, it could not last more than, say, 1000 years. The buildup of SO2 and CO2 in the atmosphere of a frozen earth would thaw it back and cause a strong GREENHOUSE condition to boot too...

  • Aaaaaarghhhhhh Global warming aaaarghhhhhhh

  • and the worst thing.... cars won't start!!

  • canadians kills harp seal pups.  let the canadians die

  • Humans survived the first Ice Age. We can survive another.

  • @TheUnknown8999 Because that was just the small ice ages that has been around for the last two million years where only the most nothern globe was covered in ice in the winters for some ten thousands years or so. This is freaking snowball earth ice ages where the hole earth all the way to the equator was covered in ice for millions of years so bacteries only could survive by living near volcanoes.

  • 95% of all life dies when this happens

  • if the world froze over today, i'd go ice skating

  • This is so typical of any TV documentary, and this is why you also don't learn science from TV documentaries.

  • The ice will melt, covering the Earth with water. Those who'll survive, will adapt to a new world. Waterworld.

    bad joke huh?

  • Damn nature you scaryy

  • poor canadians...

  • @chungwkh haha but the problem is we have a highly uneducated obese population in america..... well 2 bad 4 them

  • Nimps ?

  • Wait... we now worrying about Snowball Earth in our lifetime? I mean, didn't we just get over how absurd The Day After Tomorrow was, and that was just an ice age equivalent to the one that ended 10,000 years ago.

  • Don't worry people we can survive this I mean cavemen survived the ice age

  • @johntheant snowball earth is a different type of ice age, very few life forms would survive

  • @johntheant

    Thing is, a change like this wouldn't happen by tomorrow. It would happen over a very long time.

  • @johntheant cavemen lived closer to the equator, in the last ice age not all of the earth was covered in ice, only northern Europe, Canada, part of Russia, Chile, Argentina, Australia and parts of southern Asia. This means that they only survived it because they didn't live in it. Neanderthals lived in the ice areas to hunt mammoths. (Look where that got them! ) :P

  • JUST FIND A WAY TO LIVE ON MARS NOWW!!

  • The stone alone are barely even circumstantial evidence of glaciation. They could have been deposited by a number of other factors for one. And even if by melting ice, that doesn't tell us how big the "cube" was or where it came from, eg. how far it traveled before melting.

  • Well there goes my night...

  • Our descendants're gonna need thicker snowcoats. Brrr...

  • 1:12 Looks like a messed up keyboard to me.

  • is it global warming or snowball earth? i'm confused....

  • Ice Age looks good. Bring it on ;)

  • @gnabeel yeah i agree!!!

  • haha day after tomorrow

  • Hoth.

  • Mmmmm! Earth flavored marshmallow snowballs. I could get rich with this!

  • snow is badass.

  • were gonna freeze!! on snowball earth!!

  • The astute will note that the speculation about "what would happen if..." is just guessing based on no premise. No where do they say that one might happen in the future. AGW is here in the near term, later (~20,000 yrs) we have a renewing of an temporarily arrested ice age. Snowball? Maybe, in the far future (1 myrs), but then anything could happen out there. One nightmare possibility is that AGW remediation could get out of hand and cause one, but I think that would be the least of worries.

  • @puncheex isn't it also true that soot shot into the air from volcanoes can cool an area locally? I'm just curious.

  • @plymouthbaccaruda426: For a while. It washes out of the atmosphere within a year or so; even the gargantuan caldera volcano's emissions wash out within 6 years of the end of the eruption.

  • GRADE A BULLSHIT!

  • @Gandalfgrey93: evidence?

  • wow canadians are going to have to dig much deeper holes when they go ice fishing... dumb americans... >:(

  • ive heard that philippines experienced cold climate , philippines is a tropical country. im from the philippines but i live in japan is it possible that ice age may occur this year?

  • The scariest thing is that the climate is comming a bit closer to that every year. 0_0

  • @ingarsss

    sorry buddy, its the opposite.

  • @RainFTWs

    Oh yeah? In Latvia it's the most cold and snowy winter ever. And that lighthouse turning into icehouse?

  • @ingarsss

    you cant judge by one or two winter being cold....

  • Why are the first 2 minutes of this video just unsubstantiated speculation about what freezing poles would mean for humans? The implied leap from "the earth has been really cold in the past" to "the earth will be cold in our lifetimes!" is really amazingly stupid.

    There are all of 2 actual facts in this 3½ minute clip: that the earth has been cold in the past and that drop-stones in Australia are most likely due to glaciation.

  • how is this even possible?

  • @barr65: It is possible because without the greenhouse gases in the atmosphere the average temperature on Earth today would be -19C (-2F), rather than 14C (57F). So, if a geologic period thrusts up calcite which locks up CO2 into limestone, that could (and probably did) happen, perhaps three times: 780-735mya, 720-700mya, and 685-635mya. Happen in the near future?  No, probably not. But if it did, there'd only be extremophiles left afterward.

  • If the earth is covered with ice then the north n south poles will not melt!!!!

  • fish wouldn't die..... there are fish living under the ice on north pole ffs its one of the richest ecossistems on earth

  • @Gonzaga78: Yeah, but it ultimately depends upon sunlight for nutrients. A half mile thick ice sheet would kill everything which uses oxygen within a few tens of thousands of years. What would be left are extremophiles of one kind or another, who can live on the sulfur coming out of deep volcanic vents, or on those that can. We would have to go off-planet or invent a tech-heavy hydroponic civilization on top of the ice, which would be drastically smaller than today's.

  • @puncheex lol i got to say ur right xD

  • well that doesnt have sense because there is global warming which lead to the melting of the ice in the poles and not forming it And the global warming problem is increasing due to reckless human activities and this problem have been even discussed in one of the conferences so how would snowballs form?

  • @dida5100: No one said it was coming; in the grand theme of universal tragedy that the media often dons, they only asked what would happen to man if a snowball earth happened next week, not whether there was any inkling that it would. Global warming is likely in the near term, another ice age in the longer (20,000 yrs) term, and a snowball Earth if things get really out of hand in the farther future (1+ million yrs).

  • I like how almost none of the more recent comments have nothing to do with the video. Just taxes.

  • Canada shall be refuckulated.

  • Snowball Earth won't happen cause GLOBAL WARMING!

  • 0:31 HOGWARTS!??! =DDD

  • lol canadians dont have to dig holes to fish xD i should know im canadian :P...and i go to the store to get fish ^^...only people up in the far northern regions of canada have to dig holes to fish :P

  • free ice cream YAYY! (:

  • chuck norris made his snow ball in 3:36 minutes.

  • @stephenph um y do u keep thinking chuck norris does alot of stuff? i always hear like chuck norris does something which is and almost exaggerated, almost impossible. Why do these people keep saying chuck norris?

  • @stephenph chuck norris blows guys for free.

  • pinguin have it all

  • just eat snow and get hydrated

  • Why don't scientists create a giant microwave??0.o

  • @XxImm0rtallityxX you're obviously incredibly dumb...microwaves work by exciting the water molecules contained in the food...if they built a giant microwave and used it we would all die...even though micro waves have very low energy, they are enough to make us explode....

  • @rumive you are a complete joke.....your the dumb one mate. It was a simple joke, y the fk do you need to get serious about a joke, huh? If you imagine it, how the fuk will the microwave encapsulate the earth anyway? Dont give me simple facts that I already know...

    So next time use your common sense to differentiate between a joke and a serious question moron.

  • cool!

  • @hubz500 yeah you are right if they (humans) build lazers,rockets and nuclear weapons why cant they build something that will save our lives like a giant lazer destroys a metor that is going to hit earth...ETC

  • If this happened again humans would overcome it, we're to smart of a species just to sit there and be like "omg we're all dead let's all give up and die frozen". We would build new houses/buildings that were constantly heated, some how we would learn a way to extract energy from all the ice, after all hydro power exists and ice is frozen water. Also if it lasted a long time our bodies would adapt to the temp over time. Only way humans will ever be wiped out is a zombie infection xD.

  • DAMN NATURE!!!!!!!!!!!!!!!!!!!!!!!!

  • only mexicans survive

  • DAMN NATURE YOU REALLY SCARY!!!!

  • @2afrosamurai I thought there wasn't a REALLY in that statement 

  • @demonwolfdawg i added the REALLY cuz thats REALLY SCARY

  • @2afrosamurai lol

  • lets go to mars duuuuuuuuuuuude

  • @demonwolfdawg no wait, it colder

  • @davidlee110 aw SHIT!

  • @demonwolfdawg ....Mars FTW :D

  • @demonwolfdawg Mars is a fucking red ice age.

  • @BaxterXenon yea but its coooool

  • Ok then 2012 is better than if the whole world freezes to death!

  • don't worry guys its only a theory!it could or NoT happen.well just be prepared

  • Its a nice theory but it doesnt have alot of evidence to support it. A couple of my Geology profs have debunked or given evidence against in lectures.

  • When earth will be frozen, Global Warming will come and fix this! Problem solved

  • Omg typical.... a few drop stones in Australia and he whole earth is a snowball.... just like 1 swallow makes summer

  • aw shit its summer where i live and my house is covered with snow

  • Icy London, Icy France, Icy Philippines!

  • If it did why do we have animals and people still today?

  • @MyAero13 idk

  • @MyAero13

    Because microorganisms that survived deep in the ocean, where it was not frozen, were able to proceed with the evolutionary process.

  • o.o thats really scary!Dx

  • this can never happen

  • Meh. I live in Quebec, that would'n make much of a differance.

  • And just think "It has happened at least 3times before". Guess what..WE had nothing whatsoever to do with it, and have NO way of stopping it again...

  • im scared aaaaaaaaaaaaaaaa!!!!!

  • if global warming was true it would happen in winter when the earth is closet to the sun

  • What? seasons like winter are caused when the earth tilts, so when the northern hemisphere is in winter, the southern hemisphere is in summer. seasons are not caused by the distanse from the sun

  • i dont think so its possible because its means earth must move away from the sun or earth must be covered with water than ice earth is possible but not just like that because anyway there is south and north so one side should be warm and other cold

  • of course it was covered in a thick ice man... Ice age was here once...

  • With global warming ice is melting and winters are colder! u should know that.. if global warming continues sea levels will rise and flood continents and that is deadly with cold winters.

  • In just FIVE YEARS between 2004-2009 the thickness of arctic ice has DROPPED 42%.

    This was discovered by NASA satellite measurements. Reported 7/7/09

    Search:

    New NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning

    Global Warming is changing our world NOW. CO2 is 35% above levels for 650,000 years. In just 30 years CO2 will be over 450ppm, enough to acidify oceans to the point of stopping the growth of many planktons and corals. They are at the base of the oceans' food chain.

  • That's enough to make me shit myself

  • @Riste1986 If u dont like NG than why are u watching this? o.O

  • Well i have to compare the science with the real science, man has to know the both sides Lie and Truth.

  • @Riste1986 I guess you got a point. I like NG

  • At 2:10 I've been there! xD I went to Flinders Rangers in the holidays right now they have a big mining hole for all that kind of stuff.

  • The thing with this and the warming fear mongering is that people act like this will happen all at once or something, umm no.

  • I think your right

    the people who made this just said this bullshit to get people to watch it when the scientists have said nothing other than it has happened before and havent given any evidence it will happen anytime soon

  • Please read something and know what you're talking about before posting such a comment ;]

  • Is it bad that I laughed when the guy said canadians have to dig deeper holes to fish?

  • @EmoEthanOwns

    LOLOLOLOLOLOLOL LMFAO

  • @EmoEthanOwns obviously you know nothing about canada, typical stupid american.

  • Well they already live on a tundra, so to a Canadian. "Ehh its is more of the same-o"

  • @TheRadicalRyushin

    Not true. Where I live we can grow cactus's outside and summer temps reach 40 C. Please don't stereotype Americans as being not worldly smart.

  • You are not smart, do I need to repeat myself. And growing a cactus? Hell, I grew a cactus when I was four years old, so don't give me that shit. It is always Americans who term the easiest things in the world as though you need rocket science intelligence in order to figure. It must a miracle of intellect that you had figured out how to get out of bed this morning, huh? I bet that in it self is enough of a mental challenge, huh? Fucking lazy ass idiots who don't like paying taxes.

  • @TheRadicalRyushin

    Again you are stereotyping yourself. Canadian pay a much higher taxes on average than Americans (Illinois is a notable exception). With my $20 hour job, about 40% goes to taxes. We have 15% sales tax too. Then there is property taxes etc. etc. You didn't read what I wrote first time so I'll repeat it: We grow wild cactus's outside.

  • @EmoEthanOwns no that is actuall pretty funny, im pretty sure australia would be fine if there was an ice age, u guys could all come and live down under

  • @EmoEthanOwns lmao damn maybe the Eskimos up North do that but not here down South. O_O hahahaha

  • @EmoEthanOwns yes it is bad >:(

  • @EmoEthanOwns Yea that is bad. :D

  • @EmoEthanOwns

    no.

  • National Geographic has turned into BBC / Fox :(

  • Sounds like north dakota.

  • im lucky coz i leave in a tropical country

  • ur rite tho

  • Woah ultimate snowball fight! :D

  • Pole shift!!We will die :D.

  • Comment removed

  • Its happening now

    UltimaXproductions.

  • i know i made a mistake O_O

  • What a crap. Scientists says the Earth is becoming hot and hot.

    So, how the fuck we gonna back to Ice Age?

  • watch the episode!!

  • well scientists are only saying this bc environmentalist dont allow them to tell the truth. sciencists are now ignoring this, and telling the truth now.

    some people are trying to get to them without them being stopped.

    in this case, this is why this video is on youtube.

    -ultimaXproduction's sister.

  • dumbass

  • bullshit, there trying to scare you , no fear.

  • its true but it won't happen for like a billion years or maby a lowest of 100 years

  • U wish UltimaXproductions...u wish..

  • ya i wish it is happening O_O
