Climate Change, Chaos, and The Little Ice Age: Crash Course World History  

First. -stan

"We're trying to educate the world for free, that of course requires money" Ha!, sad but true.

The funniest part of this episode was "history is not controversial"

'History is never controversial' HAAHAHAHHAHAHAHAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHHAHAHAHAHAAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAAHA

We got 1k climate change deniers 😑

does anyone else just watch these videos for fun?? I love them so much they dont even feel educational they are just super interesting :D

This series is a cut above most other educational content i've indulged here on RU-vid. Everyone responsible for it truly deserve a pat on the back.

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

"climate is not weather" That's all I came for.

As a plant scientist, I am working on things I hope will lead to the 'cast iron ploughs of the future'. Probably not, but I'm trying.

So when will our society begin talking about sex education and overpopulation instead of constantly telling people about the need to have families and family values?

Don't tell me this is the same guy that wrote Fault in our Stars.

2:12: The viking expansion occurred during the Medieval Warm Period, not the Little Ice Age. The vikings discovered America a good 300 years before the onset of the Little Ice Age. In fact, the viking expansion could only have occurred during the Medieval Warm Period, because it was caused by an increase in population pressures in the Norse homelands due to the warmer weather. When the weather cooled, the vikings stop expanding and even abandoned their settlements in Greenland (which was no longer suitable to their lifestyle). This is really a pretty significant factual error, I'm disappointed to see it in this great series.

*Winter is Coming*

"Where's all your food?" "Well, the whole planet is colder, not just Korea." And then they were already there and decided to have a Dinasty. That could be an ending to a book.

Did anyone see the avatar go across the screen at 5:12

actually, there WAS a snowball era in Earth's history -> geologists are more creative in naming things than historians

"Some blamed it on witches, always a safe bet." LMAO

Nobody can conquer the ice age unless you are wait for it... The Mongol

2:58 - 3:16 Europa Universalis Taught me all of that :3

"We're talking about history, and history is never controversial." Every time. I can't stop laughing every time I hear that line. Absolute genius.

5:12 WAIT thats aang and appa from The Last Airbender! :D

The thing I find very interesting about this (as an AS Level British history student who recently studied 17th century britian) is that none of this really effected british economy. In the 17th century britian began to monopalise in our colonialism in the americas and in east India. We also brought about better agricultural techniques and created a new agricultural revolution. We also had a huge increase in population. Our population doubled from 2.5 million in 1600 to 5 million in 1688. We also found a decrease in disease and a better isolation of disease to stop any epidemics. The lesser gentry (the middle class) were also on the rise in this period with the rise of merchants and professions who became MP (members of parliament) later on in life showing their gain in power and influence. In fact in 1649 we decided that we wanted a republic and got rid of our King in favour of the gentry. In 1653 Cromwell a member of the lesser gentry became the lord protector of britian. Britian enjoyed a stable economy through out the 17th century. This completely contrasts to the evidence you show in this video. I believe the reason for this is that britian was able to fall back on imperialism to secure the economy when many other countries were unable to.

Nobody: John Green: Crash course is made possible by these nice people: has his own name.

4:00 Comet sighted!

Norsemen went to America in 1000AD, then they left 50 years later as the sea port in Greenland began freezing over. They didn't go to America because it got cold, they left America because their supply chain was broken, and they kept getting attacked by natives. They had been living sea based lives since before 700AD... inaccuracies like that one are very damaging to the credibility of the facts presented.

climate change happens over and over (6x in 1200 years). 13th-19th centuries, average temperatures were cooler, but featured volatile shifts bw bitter cold winters, wet summers, long droughts and weather not the same globally. 1:30 climate is not weather. 1:45 monks/winemakers/farmers kept logs at time reporting catastrophic bad weather bad harvests. less food meant more starvation disease crime riots unrest. 2:40 a couple bad harvests in a row was fatal. 2:50 list of dozen uprisings/unrest. 3:30 taxes were high food was short because harvests were bad. 4:00 fewer recorded sunspots in 1617/1618 when 30 years war began. 4:12 12 volcanic eruptions 1638-1644 producing dust veils that helped cool planet. 4:25 1642 so cold massachusetts bay froze. 4:40 1641 coldest weather ever in scandinavia. 4:55 mini ice age leads to population decline 'thought bubble': thomas c. smith: farming was the principal occupation and source of income for most families and its rhythms defined the cycles of work rest worship and severe annual variations in the harvest reverberated through family life and social fabric. 5:20 jeffrey parker: in latitudes north of temperate zone each of 0.5C in mean summer temp decreases number of days on which crops ripen by 10% and doubles risk of a single harvest failure, and increases risk of double failure six fold. harvest failure > food shortages rising food prices > malnutrition > hunger > diminish the capacity to work due to low calorie diets > disease death population decline (5:50 when not enough money for food people stop spending on other stuff). 6:40 soldiers looted food. costs of war was burdened on peasants via taxes ex. bread taxes > bread riots.

how come you do not speak about the thames frost fairs?

Learning about history is helping me see where all the fantasy writers get their inspiration from. For example, GRRM's Iron Bank of Braavos is probably inspired by the Knights Templar and Brandon Sanderson's Ashmounts are probably inspired by those 12 volcanoes.

"And history is never controversial" Lol, I love you John.

SKY BISON SIGHTING!!! 5:13

The Norsemen settled in Iceland, Greenland and North America long before the little ice age. This period is commonly referred to as the medieval warm period. The Norwegians who settled in Greenland made a living from agriculture.

why was there no open letter?

Question: I have a Geology professor who uses this as an argument against global warming being human influenced. He says we are coming out of a little ice age and that is why the ice caps are melting and the planet is warming. Can you speak to that please? It's very confusing because my Lab professor swears climate change is real. For what it's worth...I hate to ad hom the guy, but I live in south texas where there is a lot of drilling and he seems very pro oil and gas. In fact, most of the Geology dept. at my college are climate change "skeptics."

Wait, what? If you pass a law forbidding widows to kill themselves, how are you going to enforce that law when the widows are already dead?

Stay away from this comment section if you don't want to read pages of Denialism about Science.

Crash Course you are amazing af, for putting in that tiny reference to Avatar: The Last Airbender (ATLA). :3 And if anyone else saw it and likes ATLA you're a cool person. (^o^)

Ice age is freezing 🥶🥶🥶

I see far more people whining about denying climate change than people denying climate change.

A grand solar minimum is what we are heading into. Ice age farmer Adapt 2030 Utube.

John, there were no vikings in the 13th century. The Viking age ended in the 12th century. Vikings did not colonise America in search of food, they colonised it because they could sail very far during the medieval warm period. Look, I know people who believe in modern man made climate change (I'm not sure myself but whatever) like to brush away the medieval warm period because it's inconvenient for their theory that only humans can create such dramatic change to warm weather, but I seriously must ask you not to spread this kind of misinformation. You do it so rarely, it'd be a shame. In fact, the 13th century marked the period when the Norse STOPPED going to America. Good show though. :)

" History is never controversial"?! Really? You think evening history text book says is fact? It is too much politics in history. History is written by historians who write what politics tell them to write. They can skip something, add something, change some facts. History is similarly to news. If you read about same event in different books from different countries, there is different info. Same as in news. Every country says what is good for it.

When John complained about the U.S. Winter.... Please come to Canada, there was a 15 feet snow pile covering a huge part of my road one week when I didn't even go to school because we had 5 snow days In a row

The painting on 4:26 of ice skating does not, as you suggest, depict Massachusetts. It is a painting of a town in the Netherlands in winter, by the Dutch artist Hendrick Avercamp. Other than that, I'm a big fan of your videos!

I always love the computer. "THIS MACHINE KILLS FASCISTS"

APPA!!!! At 5:12 he flies by.... You are my hero.

The next 200 years are going to be... well there going to suck.

THAT THOUGHT BUBBLE WAS THE BEST (AND CREEPIEST) ONE

Did any one else see Aang and Oppa from the last air bender in the middle of this video O_O

"... because history is never controversial." Oh, John. You crack me up. I had ALL the laughs. *so says the history major*

Every video, pretty much a masterpiece

GOD DAMN COMETS!!

What's really funny is that back in the middle ages the weather being bad was attributed to sinfulness, we find out now that it's kind of true today (in a way). Only it's more about sins against the environment rather than the laws of God.

It's a good thing they had all those gas sucking, CO2 producing cars back in the little ice age so they could drive to places where there was more food and better climate. I am currently looking for an early 1400's Chevy to add to my ice age collection.

Possibly the best Thought Bubble ever.

Thank you for doing what you do John Green and company. I've been enjoying your videos for years now and have never been disappointed.

You owe us another video since last week you were a no show :(

So it sounds like warming is a good thing.

Of course Shakespeare's writing was dependant on climate. He's British. What else would he have to talk about

"History is never controversial" I guess he's never heard of *insert literally anything here* deniers

climate change is still considerd controversal?? oh w8 this video is made usa... here in the netherlands climate change is a fact. and people are now discussing how to solve it and how much should there be done, and how much money it cost.

Really glad to see a new Crash Course World History as not only do I get more of an awesome thing, but it also means you are feeling better. Welcome back, I missed the updates while you were sick.

Shakespeare is overrated

A note on the sunspots theory: during the 1600's, the sun went through a grand minimum in its sunspot cycles. This means that basically a couple sunspot cycles in a row were essentially missing for 70 years. The cycles didn't completely go away, but they were very, very significantly weaker and had much less sunspots during that period. Also, during this period of global warming we've been in the past century, sunspot cycles have been significantly stronger, with a decline similar to the early 1600's decline happening in recent years. This suggests that we may be approaching another grand minimum in the sunspot cycles.

How could you from the past be wearing a shirt from a book you haven't even wrote yet??

5:11 Hahaha Aang and Appa!

I simply cannot believe a huge portion of the comment section is "modern climate change is not caused by humans r u stoopid". I've lost my hope for mankind once more.

China 1688 : "We forbid you from killing yourself!" Emo Kids : "Aww shucks!"

Great video and great history. Are you going to do a video on the positive effects of warming like with the Medieval Warm Period and the Roman Climate Optimum two of the great period of human expansion in history? At the height of the MEWP some parts of europe were having 2 harvest a year.

Trump should watch this.

It's not hard to guess what the cast iron ploughs of the future will be. All you have to do is to apply the rule "Swords to ploughshares" to lighsabres, and... tadaaaaa: Lightploughs!

How did I just realize that this guy wrote "A Fault in Our Stars......"

If climate change is real, then home come I'm an idiot?

I just wanna say thanks cause I've been BINGING on crash course world and US history all quarantine long and its great

How many fascists has that computer killed? I want a tally!

5:12 - Aang and Appa (The last Airbender)! 6:05 Wilhelm scream

Wait.. Wait.. I need to ask.. Are the Mongols immune to this little ice age?

The poor polar bear! -my sister

I know it's sad but I am so happy he mentioned the English Revolution!

Ugh. This separation of "history" and "science". Dear Americans, please stop studying sciences as one inseparable bunch in high school and start studying them separately, as chemistry, physics, biology, and start using the term "natural science" for those disciplines becuase they are but one branch of modern science. History itself is part of another so when you say "history and science" it's like saying, "I buought apples and also some fruits." Sincerelly, Europe.

I saw that sneaky Simpsons reference! :D

the thought bubble was scary in this one :(

Um... The Qing Dynasty were outside invaders who defeated Shun Dynasty rebels and Southern Ming loyalists. The last Ming emperor hanged himself to avoid Shun rebels attacking Beijing. The Qing Dynasty entered Beijing in 1644 after defeating Shun forces that defeated Ming forces. Yes, Ming and Qing had been fighting for many years by the time Ming Dynasty fell, but it fell to Shun Dynasty.

It’s the sun. It’s cyclic. And it’s all about to happen again. Get ready for significant cooling

Dear Dad, I love you, but THIS IS NOT PROOF THAT GLOBAL WARMING IS FAKE Love, Emily

at 1:22, is that a woman being molested?

We are coming out of a grand solar maximum and entering a grand solar minimum. Don't get your science from memes, politicians, and english professors.

The topic of the Little Ice Age is very interesting. How come it was never mentioned when I studied history at school? Seems like it is something you should always keep in mind when talking about that period in history.

Point of order: The Viking expansion took place BEFORE the little ice age. In fact, it occurred during a very warm spell, when the Viking lands flourished, and had a population boom. Greenland was also warmer than now, which enabled them to establish successful colony, which was later wiped out during the Little Ice Age. ....So, please be more careful with your examples.

Can we focus about Southeast Asia next? Particularly Indonesia, Singapore, and Malaysia? And Brunei since it's territory took the northern part of Kalimantan.

I like how he says they we're totally wrong about witches causing bad weather but says nothing about how its equally dumb to blame bad weather on a god.

SIDESTEPPING THE CLIMATE CHANGE FURY IN SOME OF THE COMMENTS, I think the sentiment at the end - the idea that we can adapt to a changing environment - can apply to a lot of things besides the natural environment. For example, we're going to have to find a way to deal with the paradigm shift towards automation and how that affects the economic environment, as described in CGPGrey's recent video.

I think the whole global cooling (the 1970's), global warming (until recently), and now climate change is a weird kind of debate, especially when the metiorologists can't even predict what is going to happen the next day. But, I guess I'm just stupid and eveyone else is really smart....

I dont normally criticise Crash Course, because its really good, but I just wanted to bring up something that was frequently mentioned in the episode. There is no such thing as the "english revolution". There was the "British Civil war" (historians have started calling it British because it featured a large number of Scottish, Welsh and Irish people fighting in it) and the "Glorious revolution". Basically if you said "english revolution" to someone in england they would have no idea what you meant and would probably think you meant the industrial revolution

Someone else has likely already commented this, but the Norse did not go exploring because of the Little Ice Age - they started exploring at the beginning of the Medieval Warm Period and started to fall off toward the start of the Little Ice Age.

It is not check Prager university's video on it. They got a co-founder of green peace for the video.

They key lessons from the little ice age were: 1) How easy it was for people to blame other people for a natural occurrence. 2) The cold periods (such as the little ice age) were brutally harsh on people and agriculture while the warm periods in between were almost universally beneficial. These were periods of wealth and rapid agricultural growth ... kind of like now.

According to the UNITED climate change council, the Earth's temperature has risen .01 degrees in the last century. I'd hardly call this climate change 'warming'

Our current climate period is called an interglacial period which means the period between glaciers advancing down from the poles. We ARE 100% still in an ice age called the Quaternary glaciation. The current ice age is about 3 million years old while the last ice age called the karoo ice age lasted from 360 million years ago until 260 million years ago. The most stable periods of climate occur when there is no ice on our planet. Ice formation on Earth only occur rarely and it's presence on Earth is associated with ice ages. This basically means that ONLY one of these two things will eventually occur. 1. The glaciers completely melt allowing us to break out of the current ice age causing the sea level to rise and killing billions of people. 2. The glaciers start their advance and cover much of the planet in thousands of feet of ice killing billions of people. Why aren't climate scientists and global warming specialists explaining these scientific facts to you? The current sea level is 100% non sustainable...100%. Don't kid yourself about this fact.
