- Life on Earth has weathered boiling-hot oceans and volcanic-ash-darkened skies-but that’s nothing like the climate change we’re experiencing now. In this episode of Crash Course Biology, we’ll talk about the greenhouse effect, learn why our climate is like a tangled pair of headphones, and discover that we’ve understood the science behind climate change for much longer than you might think.
Chapters:
Introduction to Climate Change 00:00
The Greenhouse Effect 2:24
Measuring the Greenhouse Effect 4:46
Carbon Sinks 8:26
Environmental Justice 10:07
Review & Credits 12:09

Kudos for doing this episode. Just like you can't present a nature documentary anymore without referencing how climate change is affecting life, you can't discuss biology without discussing this topic. It's tragic that so many people still refuse to accept that this is a big problem, which means refusing to take the necessary steps to force a change in course.
baby boomers refusing to adjust because money is better. They'll die off before they are affected by global climate change.
The earth will survive climate change
Life will most likely also survive climate change
Whether WE survive climate change, is mostly up to us, and we're running out of time.
I knew climate change was going to effect us eventually... But I thought I'd be my parents age before it got to where we are now.
It happened alarmingly fast.
Excellent video on the topic and a great host!
People who make excuses like "oh, the earth has been this warm before" don't stop and realize that humans or the crops we need to survive were not alive and thriving in those eras of hot earth climate.
I really like his approach at presenting. Hope to see more videos of him.
Of him or with him (as the host)?
It's definitely hitting some folks way harder, like right now as I write this comment. I've been seeing "record highs" in a lot of headlines all over the place. Where I live it's really, really noticeable and really, really bad. The US southeast is "supposed" to be hot and humid, sure, but not 111F every day for a week!! We have trees dying from too much heat and not ENOUGH moisture, which is something I really never thought I'd see in this area. And I'm not sure how anybody's alive in Phoenix AZ right now >.>
And you are VERY right. We have to get every human on Earth to work together if we wanna solve this as quickly as humanly possible... sad to say we can't even get people to stop shooting at each other much less agree on climate policies.
Noo, all the recent forest fires are a conspiracy to inflate their value by Big Fire.
Got to love that despite most of us knowing this is awful stuff, the few people who refuse to see it are also the ones paying for all the stuff that causes it
"It is difficult to get a man to understand something when his salary depends upon his not understanding it."
It's not the ones paying for the stuff that's causing it. It's the ones profiting from the stuff causing it.
Yes. It’s because of all the Stuff people buy.
They put the blame every body and then they go shopping.
the nr1 polluter is the US military, good job Americans!
Yes, the big company owners caused so much damage
I'm saddened that we're still split politically in the acknowledgement of climate change. We really need a global effort to combat this issue but it looks like it's going to be an uphill battle all the way.
Remember Crash Course Climate Change
That was surprisingly not terrible. I've never watched this channel before, because I am an engineer and these things are generally too, well, general.
The presenter is great, the graphics are good, the data - little as it was - is sound, but I was most surprised by the obvious links between the ability of our planet to sustain life as we know it is only due to the Earth's natural greenhouse effect. That's pretty refreshing, and not often brought up In these micro courses. Well done!
The green house effect was originally hypothesised in the 1820s by Joseph Fourier, some three decades earlier than Foote's experiments.
Yep, but "neither of them recognized the increase in solar heat by CO2 and water in the atmosphere, which was unique to Foote's findings." according to Wikipedia
Great stuff- this is very educational. Really appreciate it!
Thank you for your clear explanation ❤
Thank you for this
You've got that 'LeVar Burton on Reading Rainbow + Dr. Neil DeGrasse Tyson' energy! LOVE IT!! 😍🥰
I love how Crash Course weaves in themes of the other Climate series into this. Also this video can be added to the Environmental Science curation playlist!
great job guys
I am in love with your teaching energy❤
Phenomenal video
This video helped me get better in my test 😊
Cocuklarim cok seviyor bu kanali ❤😊
Please do a deep dive video on the Sixth Extinction. That’s what people really need to hear.
This is such an informative video!
I see the Lavar Burton influence
Wow 🎉 very good education videos with excellent animation
When is the cells episode coming out???
I feel smarter
Very important information. Thanks for not making it about the hats 🎩, jolly good, eh wot!
Great video, applause to the speaker!
I like him
not the furbies 😭
2023(Gregorian) “Respect and dignity.” Furthermore:
This makes me want to vomit. It seems illegal to destroy our plant, I guess if ur rich enough u can do whatever want 😔
eight billion of any species is going to have an effect on its surroundings
Big countries like America, China, Russia and so on need to do more. If they don't start reducing the output we are not in a good position. The little countries like Germany, Sweden and so on can't handle it alone
Russia is no longer considered a "big" country. Germany and Sweden both have greater influence on world politics at this point.
Big facts here !!
Germany is sadly backsliding back to coal. They got rid of nuclear power and obviously Russian gas.
It’s because of all the stuff people buy.
@@Philitron128 Sweden and Poland are similar, the first country to be destroyed when the Second World War began, do you brag without thinking about the actual situation, European countries are so small, there is no strategic depth, a few nuclear bombs can solve it, you really want to be as powerful as you say, why the European Union? It's afraid that the United States will beat you, last winter you were very cold, American dad sucked your blood, you still need to thank the United States, it's ridiculous, I found that you European smart people speak almost nothing, the speech is very magical, you don't even understand the basic situation, personally I feel that you Europeans are stupid, especially from the standpoint of your country, there is no correct thinking at all
Sammy- love ya guy. But… in the intro you said “make energy”……
Eh….
Please do a video explaining how the governments of the world's massive geoengineering operations effect the changes in climate we're seeing.
So corporate power just doesn't exist in your sad little worldview. Bad bot.
Sooooo . . . explain Mt. St. Helens. That happened kinda fast.
We need these companies to start not putting so much into lur atmosphere
Yeah but corporations need to kill the entire biosphere to make line go up. So oh well.
They won’t stop as long as people keep shopping.
People needed to stop shopping decades ago.
I’ve said it many times, the Industrial Revolution is where it all went wrong.
Imagine how peaceful it would be if we had limited industrialisation, not technology but heavy industries.
Someone forward this to Xi!
Remember to share this with the Fox viewers in your life (and help them with understanding it if you have the patience).
They won’t understand until the famine of a 1.5 Celsius world, and even then,….?
😌😌😌
US THAT A JOJO REFERENCE
Can't wait until Earth becomes Venus with its runaway greenhouse effect.
I though C o2 is what plants breath?
Isn't water what humans drink? So, by your implied reasonning, an excess of water is impossible, people just cannot drown.
@@franckr6159 Yeah thank god I never drowned whenever I drank an excess of water.
CHANGE is better words than warming as in Ireland our weather is certainly not hotter but wetter
Lol
The issue that I have seen has been that most climate activists go after their fellow man rather than the governments and companies that are doing the most damage. You can't expect creatures of habit (humans) to change their diets overnight or at all. You can however hold large corporations accountable and force them into changing their practices and invest in carbon recapture.
Activists do all sorts of work regarding governments and companies, you're just less likely to see it because it doesn't involve you.
If that was possible it would have already happened.
The Activists just spent 60 years doing what you said but it didn’t work.
individualism

third 😑
It is true that consequences of famine, flooding, droughts, bad crops and even polution disproportionately affect poor people regardless their race, is because this fact that is so cruel that the proposed solutions for 'climate change' also affect the most poor people, making food, energy, housing, transportation and almost everything else
expensier, therefore making poor people less likely to have access to it.
In fact the proposed solutions make the rich richer eg Bill Gates, the powerful more powerful, and the poor poorer. How is that a good solution?
Second comment
First comment
How many times did you fart per person to save others from theirs?
What I do t understand is why very cold winters are considered weather but hot days are considered climate change.
Of course climate change is real* but the way we communicate about it is steeped in political sensibilities that date back decades
It is brutal self interest. There is good reason why conservatives mostly believe in zero sum game theory. They do not care, are interested, or believe in common good. There is nothing sensible about that, just one political force representing egocentristic and sociopathic people.
@@Pecisk Spot on !
Electric cars👎
Why hasn't anything al gore said would happen come to past...n I've never been in a private jet so I'm sure my carbon footprint is smaller than any company or politician ...maybe the ppl in charge should practice what they preach...I'm sure af1 isnt even a green/eco friendly airship
Gore isn't a climatologist, who cares what he thinks? Predictions published in journals have been remarkably accurate. Get your science from the scientists, not enthusiastic laypeople.
Because Al Gore was a politician and not a science communicator. Yes we should be putting much more pressure on corporations or governments than individual working class humans. None of this actually makes climate change not true.
Medicine is a science way older and more advanced that climate science. Hi many times people goes to doctors and specialists, get tested with many technologies and still medical scientists can say what’s the problem or how to fix it?
The reality is that we know very little about many areas of science. Particularly climate science has proven to have been wrong many times in the past.
The worst part is that real scientist are silenced if they have theories distinct to the mainstream. How is this science?
PLEASE BE VEGAN, IT IS A MUST.
JUST REQUESTING YOU ALL
im sorry to say chicken wings are soo goood 🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤🤤 really if i became vegan this will became the end of the world😐pasta with chicken 😘
there is nothing we can do
:)
I will respect that you refuse to eat meat and products made from animals. Please respect that I do.
Every time a vegan tries to control my life I buy another pack of bacon
That does nothing. Just a way for people to feel important and better than others.
Spreading lies is not cool
