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

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

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.

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.

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

First. -stan

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

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.

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.

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

*Winter is Coming*

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

"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.

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

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

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.

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

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

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

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

"....I'm Your History Teacher!" BEST LINE EVER!

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

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.

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.

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

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.

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

Possibly the best Thought Bubble ever.

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

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

Ice age is freezing 🥶🥶🥶

i just love your crash course's , especially the cause and effect parts of this one...really puts things in a clearer view

Every video, pretty much a masterpiece

4:00 Comet sighted!

Amazing stuff, John! So interesting. Loving the new format and subjects. Thank you!!

You learn something new everyday! I had no idea there was a mini ice age only a couple hundred years ago! Thank you Crash Course

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

SKY BISON SIGHTING!!! 5:13

I love these presentations / snippets ! Quick refreshing boost of knowledge and intellect ! A spritzer for the brain! Good job!

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.

5:11 Hahaha Aang and Appa!

Requesting 10 hour loop of John repeating "climate is not weather".

Another great video guys, I love this channel :D

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

why was there no open letter?

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?

thanks to keep it free! i love crash course

A very informative video as usual. I'm always intrigued by the content of this channel. :)

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?

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

Thank you. You, guys, are THE BEST teachers

Awesome. Love this channel, the explanations are great and its a plus that the host is HOOSIER!! Keep em coming.

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

THAT THOUGHT BUBBLE WAS THE BEST (AND CREEPIEST) ONE

Crash course is AWESOME!

thanks for teaching me so much John Green.

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."

the thought bubble was scary in this one :(

This series makes history fun and sexy, thanks John Green

while it shouldn't be surprising that a person has gotten better at something he's done a lot, that was the most thorough and well argued clip you've made. much kudos and keep up the good work!

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

great topic! keep them coming

I Appreciate Crash Course, Thank You.

I saw that sneaky Simpsons reference! :D

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!

One of the best episodes yet~

great stuff as always John Green.

"I would be as good as [Shakespeare] if only we were in a time of climate change." - John Green #humblebrag

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^)

"Let's go to the thought bubble". My favorite part of every episode!

Hi John Green thank you for these videos, I'm 24 I never could afford college so I like to watch your videos to educate myself. Many many blessings hope the world gives you all the best things

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.

We got 1k climate change deniers 😑

Whenever he goes to read the end credits it sounds like he is about to burst laughing... its hellerious

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!

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.

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

Crash Course - would be great if you could do an episode on the medieval warm period - the climate anomaly that preceded the mini ice age.

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

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.

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

Another great video - thanks!

u are just awesome ..john green..

GOD DAMN COMETS!!

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

"I am your history teacher!" 7:42 Idk why I found that so funny

Cool video 👍🏾

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.

5:13 last airbender reference! love it

I learned so much about little ice ages in geography i feel like John :D

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.

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.

thank you for mentioning the welsh

In my social studies class we've watched so many of your videos xD
