Throughout Earth’s history, climate has varied greatly. For hundreds of millions of years, the planet had no polar ice caps. Without this ice, the sea level was 70 meters higher. At the other extreme, about 700 million years ago, Earth became almost entirely covered in ice, during an event known as “Snowball Earth.” What causes these swings in the planet’s climate? Lorraine Lisiecki investigates.

Am I the only one who almost passed out laughing at the Earth moving around the sun and shaking its arms like that?
No, we did too. :)
Hahahaha me too
😂
it's cute
Alyson Henrique i was more wondering if the sun was happy because earth was happy. Or is he happy because we are his more favotite planet in our system, the only one that has complex life?
*Snows a little*
School: closed
*Ice age*
School: Opened
So true though
If we were in an ice age, then we would have to go virtual. Forever
Only in America.
Here in Sweden when we get like a lot of snow, they don't close
lol
@@rullvard8245 well even then the northern US usually still does school unless it's above like a foot. However, in the south, especially places like Dallas, TX, and Atlanta, GA, where it's very possible to see snow, but it doesn't happen often enough for any preparation to be made, that's when a tiny bit of snow will cancel school
The animation was so cute in this one
Especially the animation of the earth circling the sun.
Very much

TedEd: When will the next Ice age happen?
1.1 million people: can't wait!
Jesus loves you ❤️
It's amazing how ted ed always seem to have the answers to the random questions that pop up on my head in the middle of the night
Thanks, buponki 1230!
You're saying global warming is a dream that scares children? Yes, it is. The reality that should scare you, is how these cultists think children should be killed by gory explosion, if they dare to not drink the poisoned flavour-aid. Thankfully, kids are getting smart to it, regardless. Younger people and educated people are falling away from global warming religion.
Maybe it was when the sea froze over, that the shift started?
Van Ivanov A person denying Climate Change with a Russian-Esque name is so beautiful
"Answers", more like guesses by so called scientists. It is impossible to measure how many thousands of years ago something happened as precisely as this video and other sources suggest. I'm not denying climate change but us humans have a negligible effect on it. Not saying greenhouse gases are not bad either, they got their own negative effects. I'd say we are closing on the temperature peak, and after that the earth will start cooling down. Nobody can prove the 100 000 year cycles, what if there actually were shorter time periods between the ice ages? Or that there were a lot more of them than what the current knowledge tells us?
You know what this means...
More ice age movies
Lmao😂😂

4:26 when *I* was a student, we were told the only thing we could do about atmospheric CO2 was give our allowances to those "save the rainforest, buy an acre" deals. Whatever happened to those?
Y'all got scammed

Also TED-Ed: wE sHoULd uNdO tHaT
yup! 🤣
I wonder if it has anything to do with the sea level rising by 200 feet. 🧐🤔
please never stop doing this. i love this videos. better than food to me: feeds my brain
Make sure you keep eating, though! :) czcams.com/video/xyQY8a-ng6g/video.html
oh thank youuu that video actually helped me to want to eat healthier ^^ ❤
Yes... instead of giving the people bread, they are fed on propaganda. America has terrible issues with poverty, and children not being fed enough. Yet, all the kids have iphones, and access to plenty of government instructions on what to feel, think, and want.
well, English is not my first language so i probably couldn't get what did you said perfectly, i think its don't have a fancy phone like iphone but its all up to you to search for your brain food. i mean i am watching this video instead of slime videos. idk how to cure those issues but more children search the more they'll wake up and see what is going on
tell me what is the lie here
Really love the animation in this one
Thanks!

Well this video gave lots of information leaving only ONE?
When will be the frea***kin next ICE AGE?
It's overdue but global warming
@@reinatr4848 its estimated in about 1,450 years or so but it still will happen no matter how bad co2 in the air it just will be in a smaller scale
Anytime. Earth is already overdue for its next ice age. If man made global warming is real then we can thank it for saving our race, a new ice age would be far more harmful to our species than the temp going up a digree or two.
@@braxxian a deg or two is going to keep increasing though
I saw a CZcams video on the beginning of the next solar Maunder Minimum and that time is now. Predict a cooling trend fir the next 20 to 30 years. Hope it isn’t the beginning of the next ice age.

Hey, TED-ED, I have a video idea for you guys. "What would earth look like today, if there were never humans?"
thats awesome

woah they made a video of this.
We would be in an ice age. They kind of said it in the video.

Actually global warming can cause Ice Age
Nicely explained and easy to understand
ikr we can get answers on other places too but their explanation is the best
I agree soft kitty..
Most of the time I prefer Ted Ed
Indeed, a cartoon for children. Very good for scaring little ones into believing anything. We can also tell them God is going to send the rapture, by a similar cartoon.

WINTER IS COMING
🐳 It "Came"
Nikka Kuran Literally every Game of Thrones episode
These animations are so well done and help me understand the video much better. Keep it up!
The sun and earths faces are so cute!! I just wanna hug them!! 💖
When you think of it the main reason some people deny this is because of how expensive it would be to fix
That is correct. Killing millions or billions of people does not seem like a good solution. That is what would happen if you crashed our economies the way some environmentalists would like us to.
no one is ever to young to inspire or affect positive change; and this animation was absolutely wonderful!
Hi! I always learn so much! Keep it up!
must commend the animator. it takes a lot of hardwork and creativity for each clip
I believe that no matter what your age is. You can do something great to help our mother earth. Its not the end, we can do something.
I mean for us it would be the end but for the earth its just another cycle. So don't worry about the planet. She's fine. Unless we somehow managed to blow it up or something. Then she'll be dead
Let’s not forget when there were so many huge plants (including the massive ‘scale trees’) that too much carbon dioxide was being sucked up, leading to the reverse of global warming and causing an ice age.
Those same plants also increased the oxygen level so much that Arthropods increased significantly in size, leading to three metre centipedes and eagle-sized dragonflies. What a time the Carboniferous period was!
in my city it was snowing well till 2 years ago. this year we didn't see any snowflake :c how can winter be warm!!! i miss winter and i wish all humanity was aware of the danger
that actually happens naturally, have you watch the video?
''depending on how much additional fossil fuel we burn''
co2 level is 410.31ppm now and increases fast, 5th warmest January happened this year.
do you think everything happened naturally or we ruin mostly? i think we should focus on how to fix it
Snowball Earth is a much worse fate: czcams.com/video/P8q13Fqj6MA/video.html
Most human population and life on major continents extinct within the first year.
And from that point forward, it just gets worse... for about 100,000 years or longer...
@@matheusd.rodrigues429 we should be _cooling,_ not _warming_
@@idontneedaname318 hotter is better
According to the geological survey, we have stagnated on the low end of the interglacial temperature scale.
In other words we are far from reaching the past
high temperature.
Given that the tilt/wobble of axes is receding from its peek of 24.5 degrees 11,000 years ago (end of the ice age) to present 23.5 means we are headed toward cooling.
And according to the geological graph, we are like on a washboard with temp's bumping up and down.
The tilt of axes is on our side, proven to cool temperatures in time.
To say warming is the cause of the past 150 years is ridiculous.
We have been in this stagnant interglacial period for hundreds of years.
But as the degree of tilt recedes toward 22.1 degrees, we will be cooling.
We don't know when, but Minnesota is ready. If you ever visit here from sometimes October to May, we have powder like crazy. We also have many farms and orchards that produce food and oxygen. The town I live in has more trees than cars.
It's 2020 and there's rumors that's it's gonna happen this year
What’s gonna happen this year?
It can't happen in a year
Hey guys december 31, it happened
When will be the next ice age?
Me: when that damn squirrel messes up with the iceberg once more.
Which application did you use to animate the video? Plz reply.
The earth spinning around the sun was so cute!
So will there be another ice age, even a mini one. Like when the River Thames froze over for several years? Great video by the way.
It's a horrible video. I work in palaeoclimatology, and it completely failed to address its own question, and failed to address how "fixing the planet" would cause northern North America and northern Europe to cease to exist.
Climate activists on both sides are wrong.
@@tallard666any good videos you do recommend on this from your field of research?

Thank you, that was very interesting!
Great 👍 work !!!!!!!
Hello Om Chadha, I'm MurChadha.
My question is if we just stop increasing our carbon emissions rather than completely going carbon neutral would the natural forces that push the earth towards cooling eventually override our carbon footprint and push us back into an ice age?
mmm yeah that would be interesting also yeah idk if we need to go completely carbon nutreul
Anyone know what software they use to make the animations?
November 2019, Florida, 6 degrees Fahrenheit below average for the month, so far.
Can you do a video about being judgemental and more perfectionism?
Freaky Freaky hey that's a cool concept
I'm so happy this channel exists, our teachers does not want to learn us these things so I can just watch this channel! ;^;
a teacher teach. YOU learn, so it is "our teachers don't want to teach us these things" or "our teachers don't want us to learn these things"
I'm sure many teachers would *love* to teach you this sort of stuff, its just there's a limited amount of time you're in a classroom, and a set curriculum they must adhere to.
Very nice animation and the narrator also has a very clear and nice voice😊
Everyone: The Ice Age
Geologists: *THE LAST GLACIAL MAXIMUM*
This made so much sense to me. I always thought/believed that climate change was just a natural process but once I heard the nifty fact that scientists studied air bubbles in Antarctica, I changed my mind. We should be cooling but are not due to the amount of pollution we create. Makes perfect sense!
Yeah..... I'll take the heat, thanks.
If history repeats 90,000 years.
Hm, you really missed the info. We are 4k-8k years late on the glaciation cycle (Milankovitch Cycles). Re-glaciation SHOULD be happening in the next 5k years. But it likely won't, which will be catastrophic for humans. But the rest of the animal kingdom will be thrilled. I wrote a full response in the main comment level.
Awesomely great animation 👏🏻👏🏻
Thank you soo much for such beautiful and informative videos
As we head deeper into the Solar minimum cycle.
what about the mini ice age that is suppose to come between 2030 and 2040 .
Oppenheimer report and others can tell you about that like iceagefarmer adapt 2030. And check out behind the green mask by Rosa koire. czcams.com/video/hgGnQFReS7Y/video.html
@@Lifecomesfromwithin not sure what your video was but it's a dead link now.
We have been falling into the mini ice age for the past three years; the earth has been cooling since the year 2000. we've lost almost all of our sunspots. this is described as I said by Ice Age farmer, adapt 2030, Oppenheimer Ranch project. Those are CZcams users. They base their work on dr. Valentina zharkova who has been the most correct in predicting the last three solar cycles and has been terrified to say that we will fall into a mini Ice Age worse than the maunder minimum. The maunder minimum history is in Ice Age farmer Wiki. We will have a breakout of it in 2035 for about a decade. You got some misinformation about the dates possibly from frauds who don't want people to realize it's already here. Helps with depopulation if people die in the cold. The climate change hoax is described in the Iron Mountain document around page 33. In the Google search box you can put Iron Mountain document stop the crime.net and a PDF should come up. I keep lots of things in my favorites and liked videos as well. And I did Gus, find some Rosa Koire videos, although that particular link was from a deleted account. I just watched another very good one about things and I will post the link to that next.

If the world has gone through periods where the oceans rose dramatically and then fell dramatically. Then what is the problem with it happening again, even if it is caused, more or less, by humans? Yes, it would hurt island nations and coastal regions, but the changes would happen gradually over about 100 years, according to this video. That's a good amount of time to come up with a way to either evacuate these places or defend them against the ocean; and enough time to follow through with the plan/plans. Also, something interesting about rising sea levels, the Sahara desert used to be a massive jungle when the ocean level was higher. So, we would lose current coasts for new ones, and, potentially, gain some arable land from deserts; also the land under the ice sheets, we would get that as well.
The issue is it won't stop after 100 years, but would get worse and worse.
Also this would cause refugee crisis, which would make the ones from the past look like a joke.
The rate of change. Global temps increasing at 2 degrees per 100yrs is too fast. It's roughly 100 x the speed the climate usually changes. Humans can't adapt that fast and neither can plants and animals. That's why we are already in the 3rd greatest extinction event in Earth's history.
Also, instead of gradual change that closely follows the previous cycles of climate change that we can study and then prepare for. We are changing the climate in a manner that has never been seen before and we can predict exactly what will happen and so we can plan properly. For example, we now know the Ice caps are melting much faster than the rate we thought they would melt 10 yrs ago.
100 yrs is not much time to move 60% of Humans and even if we did that we would be just giving up on plants and animals.
And 100yrs from when? We've been warning that most coastal cities will be uninhabitable in 100 years for 20yrs now and people haven't started moving cities to places they be safe in 2100. Some cities are making small changes to defend against sea level rise that has already happened but those defenses will be overwhelmed soon too. By the time enough people realise they have to move most peoples and cities to entire new locations we might only have 25yrs, not 100.
It's way easier to do small change now when it's easier, than making HUGE change later when it's nearly impossible.
I definitely agree with your final statement, that it's easier to make small changes than it is to make large ones. But, what kind of small changes? Assuming you mean solar and wind energy, the main issues are the lack of reliability (we can't force the sun to come out when we need it); and the fact that producing solar panels/ wind turbines requires a lot of energy and produces a lot of toxic waste. That lack of reliability has already proven to be a big issue. In Germany, all of the power comes from green energy sources, however, there have been periods where there is massive energy waste, due to the fact that they can't store it all; and there have been periods of energy drought, where there is not enough energy and cities don't have any power, this can last for days or weeks before it is resolved. Even though I agree that it is easier to make small changes, I just don't think switching from coal/oil/gas to solar/wind would be an effective enough way to stop there from being huge issues in the future. Massive energy droughts would cause instability and people, potentially in large numbers, would die or suffer because of it. Plus, what's to stop the world from deciding to warm up anyway? What if we make all of these changes and we still have to move people inland? My point is that there are too many potentials, no matter what we decide to do, making a big decision now, like switching to solar/wind, would be rash and not through enough, and might not be the most optimal choice we have. Regardless, arguing about it in the comments of a CZcams video won't solve anything. So, agree to disagree?
Christiangamer14 sorry to correct you, but in germany we don't produce 100% of our energy from green enerhy sources. We still have some nuclear and coal power plants running.
+Christiangamer14
"So, agree to disagree?"
Sorry but you base a lot of what you write on wrong informations. Thoser are not opinions, but pure facts.
For example:
" In Germany, all of the power comes from green energy sources"
Not true, Germany is investing a lot in green yes, but they still us a massive amound of coal, which is one of the dirtiest, but also cheapest ways to produce electricity.
"massive energy waste, due to the fact that they can't store it all;"
It is possible to store, it, but wasting it and using coal instead is cheaper, cause the coal power plants are already there. To store the energy, new infrastructure and new investments would have to be build. There is a way, but not a will.
"where there is not enough energy and cities don't have any power"
What are you even talking about, I live in Germany and the last power out I can remember was over 20 years ago and it was when I lived in the US, where we had power outs once a month at least. Germany has one of the most reliable energy grids in the world.
"the main issues are the lack of reliability (we can't force the sun to come out when we need it)"
This is also a total misconception. Those sources are super reliable, as there is no more reliable source for energy, than the sun. Yes we can't force the sun to come out, but we know when it comes out.
There are also many reliable ways to store energy. For example in Germany they have some test power plants, where renewable overproduction is converted into "natural"-gas and pumped into the pipeline grid, so it can be used a half year later or the next day.
"What if we make all of these changes and we still have to move people inland?"
We will have to make those changes anyhow. The later we start, the longer it will take.
This argument sounds like, I don't know if putting water on my burning house will safe it, so I will continue puring gasaline in it.
1:26 my mind during math
I know we won’t all be alive then but it’s still scary.
thank you for the film.
we are in a inter glacial period that is going to end soon and the ice ages will come again there will be no stopping it.
Even though I am a student and young but I still feel that all our individual actions impact the global climate change and we can reduce it on individual levels by reducing our demand and dissatisfaction
Thks for making the videos ,we learn more information from your videos..
Try checking out the grand solar minimum...that is what will affect (and is affecting) our climate.
And yet during the current minimum, temperatures rise and Arctic ice melts. This year even the year over year modest growth of the Antarctic ice sheet got reversed. Image what happens during the next 60 years.

1:38 These aren't the only dynamic that effect the Earth in this way. The Solar systems position and movement through the Galaxy have an impact as well.
Good teaching.concept made easy.thanks.
Just send this video to any climate change deniers. It's just science!
I had a feeling the earths wobble affects the sun's impact on us. Remember, we, humans are only a fraction of the earths time line. Anything can and will most likely happen with or without us
Your comment didn’t get the ‘like’ from the channel, because what you have wrote make actual sense.
Along with spreading awareness it is better to evolve new ways of reducing carbon emissions as well as from atmosphere.
Awareness as a single effort will never work
1:36 this looks like me trying to dance😐😂😂
So if I understood correctly, our CO2 emissions are keeping us from being in an ice age???
Yes. It's keeping us from slowly moving towards an Ice Age in 10,000 yrs. An Ice Age that will only be equivalent to a normal Northern Winter now, for which we will slowly adapted to and prepared for.
We've avoided this natural climate cycle that Humanity has survived before by crash heating the Earth in a way the planet's eco-system can't adapt to and has helped kick off the third great extinction event in Earth's History and putting Humans in a race for survival that gets exponentially more difficult whilst simultaneously stripping away the resources we depend upon to live.
Sorry I was being a bit cheeky. I do understand what you posted above. I moved into a house 4 years ago after college and have managed to reduce my gas and electric bills by over 65% by doing renovations to the house. As I save money I am able to do more like last week I put more insulation in the attic. Saving up to replace a really old refrigerator with a smaller much more efficient one. I know my little changes don't help a lot in the grand scheme of things but it's how I know how to be more efficient! Thank you for the reply!
MyWasteOfTime
Well done! Sarcsm in text can be hard. :)
No, the sun is the biggest factor in ice ages. There are cycles known as the maunder minimum where it stops producing sun spots and temperatures cool. It's likely there will be a very long period of 90000 years with few sun spots and 10000 years with lots.
my point exactly I don't understand the problem either. earth have a history to become cooler our green house gases is keeping it warmer means warmer summer will melt the ice or keep it from stacking up. means no ice age. yay! Why is this BAD.
i hate the coments before 10 min
Polox 😂 lol
Like when its said that sea levels will rise say 50 feet, does that mean 50 feet higher up? meaning deeper, or does that mean 50 feet further inland? very big differences that are never really clarified either way within this and several other similar videos ive watched.
I feel like there's nothing I can do even though I'm not young... I really feel quite hopeless about the climate situation, even though I know that there are so many amazing people out there making a difference.
John C F how old are you?
Chill out. Life is too short to worry about the climate hoax
@@alanbiancardi2531that's selfish to not think of our future generations.

Y'know why there were ice ages?
god accidentally put the Earth in his freezer
Wait aren't we in a warm stage of an Ice age ? I thought the (most) famous Ice age we know never ended
animation was AMAZING!!!
So, does the ocean get more acidic during glacial maxima?
I love the ignorants saying that it is just propaganda.
“When will the next ice age happen”
“Derails the subject, starts talking about global warming”
Question have been left unanswered!
so what happens when the sea increase by 10m? Besides the fact that several land areas would be covered by water, what other impacts would there be?
weakpig water absorbs sunlight very well, so it would get even hotter : p many species of animals would likely move north.
The best way to fight pollution is to limit the amount of clothes you buy per year and to shun fast fashion. An example of this is buying from thrift stores and repairing your clothes.
Here come the climate change deniers 😕
Climate change is a hoax!!
Am I doing it right?
Hey you reading this, if you don't believe in climate change go and watch potholer54
The Earth Is FLAT !
Most of us couldn't be bothered to reply.... We are out there though lol ... MAGA!
That humans cause the changes. They are natural, have been for millennia and ain't gonna change no matter how much money or Carbon reduction we throw at it.
I get the feeling that someone is going to take some of this out of context to claim that the current global warming isn't something we need to prevent. The global climate has been much warmer and colder than it is today, however the current level of human activity induced global warming is dangerous due to the rapid rate at which global temperatures are rising.
Yeah. It doesn't sound that dangerous. I think you are paranoid and I don't think it's going to be a very big problem.
My mom: "when you leave the refrigerator door open"
Gradual longterm cooling since 1000s years. Suddenly with industrialism upward warming curve. So, what is so special with the warming trend in our time compared to the warming trends of the Minoan age, the Roman age and the Medieval warming? Those warming trends were transitory. How d'you know the last warming tendency is not transitory, too? How do you know the contemporary warming is due to Industrialism, and not due to natural factors like the earlier warming periods? In which case it would have happened regardless of human impacts?
Chara Choppel it said the co2 in the atmosphere is at an all time high. They know this from Antarctic ice core samples. Next time watch the whole video.
