- 034 - Global Climate Change
In this video Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans on the planet. A discussion of the greenhouse effect and greenhouse gases (including water vapor, carbon dioxide, methane, nitrous oxide, and CFCs) is included. Countries have committed to reduce through both the Kyoto Protocol and the Paris Agreement.

Hello Mr. Andersen, Thank you for keeping these videos on your channel, I am a mexican girl training for my TOEFL test and It has been the best way to learn academic vocabulary because all the key words are put on context and the speed of speach is adecuate to a good practice. I waste many time looking for academic vocabulary and always founding boring lists of words or people repeating "specifics" vocabs, until I discovered your channel and It make a real difference in my learning. I encorauge you to keep it. Success!
WELL,THAT'S REALLY REALLY WONDERFUL WAY OF PRESENTATION....EXCELLENT ...KEEP DOING MORE SUCH VIDEOS ...
Very informative! Thank you so much
you explain this sooo much better than my teacher thank you
Excellent. Thank you Paul. Very well done. I like the way you get viewers to pause the video and try to fill in the gaps. Helpful!
this was so good!
Thank you so much, I am watching this video with three of my closest friends in my life. We enjoyed this so much, very informative. Keep going, sir!!
Very hopeful thanks alot am watching from Zambia 🇿🇲
Good video! :)
impactable
Thank you so much for trying to educate. Really well-done video. Much appreciated! Subbed!
worth to watch your videos..thanks, subscribed!
Thank you so very much for taking a topic I know little about and making it simple, and quite understandable for people of a wide diversity of educational backgrounds. I'll be back to you when I have similar inquiries. Well done.
sir make some videos on environmental economics topic like pigovian tax,material balance model n other important topics. n thank you so mch for you understandable video.
helpfull
This is perfect material for my essay on global climate change.
And by the way I find all your videos incredible to get a better understanding of biology. Big thank you.
I have a question concering deforestation, I've heared it has one of the strongest impacts on influencing the climate change.
Would you confirm that, if so, to what extent?
Read up on the "Carbon Cycle" on Wikipedia man. Carbon Dioxide is being emitted into the atmosphere and taken from the atmosphere due to both natural and unnatural means.
The main point is that we take large carbon deposits that has been naturally stored in the ground for thousands of years (fossil fuels), and we use it to produce tonnes of CO2 in the atmosphere from transport and industry etc,,, on top of natural means, tipping the balance so that more CO2 is in the atmosphere.
We can encourage behaviours which counteract this by either capturing carbon dioxide in the atmosphere by artificial means (energy intensive and inefficient though) or by growing more forests where the plants capture the carbon dioxide from the atmosphere.
By destroying forests for land space and commercial operations, we are lessening the amount of carbon dioxide that can be taken from the atmosphere. We are causing both increased CO2 emissions into the atmosphere, and decreased CO2 Absorbsion from the atmosphere. It's all about balance of the carbon cycle.
Yo shoutout Mr Powell and APES!!
You are my hero in teaching
Thank you
is there a way to do this simulation in real life? is there a handheld meter that can measure greenhouse gases and temperature that I could replicate on something scaled?
I like this video

Could you perhaps cover some longer-term projected effects, such as anoxia/euxinia after slowing of the thermohaline circulation?
Amazing Video! Thank you so much!
really good video, but what i keep missing from those simple visualisations is the following.
the sun also emit IR radiation (48% of the total solar energy output?) as does everything above absolute zero.
those IR photons coming from the sun, are they absorbed by GHG in the atmosphere or is there a mechanism like Ozone in the stratosphere that already deals with those photons?
All because of you, my IB life is easier.
My Running Start life is easier!

I love you
Extremely. helpful
Thanks a lot!
I do love the irony of flying everybody out to a conference to talk about how to remove unnecessary pollution
Do you think people from Australia and the United States and Brazil can walk to Paris?
@@romano3839 Do you think the technology didn't exist to do a video conference call? Go take a seat.
@@Lolaroflwaffle Do you have a lot of experience with a conference call with 195 countries speaking different languages with translators helping out signing a historic achievement in climate science over the internet? After you.
@@romano3839 Imagine thinking they don't have plenty of time to converse prior to it. You are acting as if this kind of shit has to happen in a single day. Most countries change nothing regardless of if they supported a global change or not. There is 0 reason to fly people out, it is only done now as a display to media.

How does agriculture impact climate change? Does photosynthesis play a role in climate change?
Yes, Photosynthesis plays a large positive role against Global Warming / Climate Change.
Basically, CO2 is naturally being put into the atmosphere (through processes such as respiration of animals, volcano emissions etc...) and taken back out of the atmosphere (through processes such as Photosynthesis and Ocean Absorbsion). This is part of the carbon cycle.
By producing tonnes of CO2 into the atmosphere through transport, industry etc... we are adding this amount on top of natural sources, unbalancing the Carbon Cycle so that more of it is in that atmosphere than is usually regulated. This causes global warming / climate change due to absorbing infrared radiation from the earths surface and turning it into heat due to kinetic energy of the molecule vibrating.
By growing more forests, we can help counteract the extent of global warming / climate change by encouraging more photosynthesis, and thus more carbon being stored back into the ground and away from the atmosphere.
Another way is to encourage greater use of plant agriculture rather than animal agriculture. Crops will absorb CO2 to grow before they are sold to supermarkets, where as animals produce methane into the atmosphere as they grow (another greenhouse gas) and no CO2 absorption occurs.
Unfortunately, the only way plant agriculture can be encouraged and animal agriculture discouraged is through supply and demand. If people want to eat junk food in favour of a balanced, highly plant matter meal (like veg, potatoes, fruits, lentils and beans etc...) then animal agriculture will only continue to be encouraged over growing crops, as it is profitable.
Shrubbery thank you
Excellent lecture. I do have a question concerning CO2 being, as you put it, "the big one." I've heard that methane is a bigger threat when compared to CO2 regarding the impact on warming of the planet. Is this true?
+l CLOUD l Methane has indeed a much higher Global Warming Potential. and the levels are rising.
Yap methane is a stronger green house gas, but it doesnt last as long in the atmosphere and its emissions are alot smaller.
+l CLOUD l Methane has a larger effect if you take a fixed number of molecules. E.g. one molecule of methane is responsible for about 40 times as much warming as one molecule of carbon dioxide. I'm not sure about the exact number but that's about the right ballpark.
But there's much more carbon dioxide than methane in the atmosphere. About 200 times as much. 400 part per million for CO2 vs 2 part per million for CH4. So most of the warming is caused by carbon dioxide though methane is still a significant contribution.
Yes, but due to the extent of Animal Agriculture on the planet, Methane levels are also drastically rising.
Not even mentioning how a big part of the positive feedback loop which will drastically speed up global warming to the point of no return is the melting of perma frost deposits and methane stores which will drastically increase methane concentrations in the at,ospnere.
lgela binding needed
how water vapor causes greenhouse gases
"work together" that's what i call an optimist, lol i wish i could believe we can do that
🙏🙇thanks😅
uhh...what about animal agriculture?
He did mention in the video that Methane emissions was largely caused by Animal Agriculture. So at least this is a science video that actually covers that aspect!
Well were all screwed then.
Hey Bozeman who are you voting for?
Grow trees everyone to lower carbon dioxide. Trees consume carbon dioxide from air and convert it to oxygen. The people and businesses that cut down trees have to reforest.
Its sad reading all of these ignorant comments... just watch the damn video.
Hello to other sowell class kids that watch this
I fully trust this channel how ever I wonder how much this channel trusts the data it is using for it's video .
If this data is from the IPPC you may want to look at the people questioning the IPPC as they make some very good points on the IPPC manipulating their data .
But is it a hoax?
Edit: This post is a few months old, but if you know why please reply.
Why do charts always show a very short time span? 400,000 is very short considering the history of the Earth. A few degrees is a very small change compared to how high temps used to be. It was much warmer during the Triassic period. Look at a chart of over millions of years. The Earth's temperature today is in a trough.
Also, if CO2 is a driving factor of temperature, why doesn't it correspond with temperature on charts going back millions of years? Sometimes they go up together, sometimes they go in opposite directions.
What are the other factors? How is the relation between carbon dioxide and temp proven as causational?
There are no proofs in the video, only statement of position on the topic. Also, none of the data goes back more than 400,00 years, where there are only small variations of greenhouse gases.
You're confused. That's not a proof. That's at best a basic outline, a claim of what's happening. A proof involves rigorous explanation and data. A simple simulation, (an that's being generous calling that a sim) with no cited numbers or formulas is not a proof. Anyone with some rudimentary programming knowledge can easily do up a program claiming the earth will freeze over tomorrow. That doesn't prove anything.
"...even most climate change deniers..."
More leftist twisting and contriving to fit into your overly simplistic boxes. Nowhere have I denied that the climate changes. If you actually comprehended my first post, you'd see that I know there have been significant environmental changes, even more significant than what's being warned about.
You've done nothing so far but parrot back leftist political talking points and taken a big dump on science.
You don't even know what you're trying to argue against.
have you watched Cowspiracy ? Are you vegan Mr. Bozeman?
SECOND COMMENT!!!! HAHA
Losing mad respect.
+John Mastroligulano gaining mad respect.
I don't know why people don't ask me more questions all I have is answers. OC
I chose an electricity degree but I WOULD have chosen climate science if I hadn't been afraid of Trump being reelected. Maybe its not too late?
i caught a lie in the first 40 seconds. so goodbye
What was the lie?
@@coopergoss350 Human CO2 is a tiny % of CO2 emissions
“The oceans contain 37,400 billion tons (GT) of suspended carbon, land biomass has 2000-3000 GT. The atpmosphere contains 720 billion tons of CO2 and humans contribute only 6 GT additional load on this balance. The oceans, land and atpmosphere exchange CO2 continuously so the additional load by humans is incredibly small. A small shift in the balance between oceans and air would cause a CO2 much more severe rise than anything we could produce.”
@@marnovescovi9300 ok, thank you.
@@coopergoss350
THE LIE IS "greenhouse effect" warm the planet. First, it doesn't exist, second what warm the planet is adiabatic compression, a negative work of gas that is squished by gravity.
So 99% of all climatologists, meteorologists, biologists, etc. are either lying or wrong about human caused Climate Change and global warming?
99% of them are in a vast conspiracy or inept at their profession?
There is only one way to cure the global climate change, and that is for all of us to turn back to God and pray for forgiveness and for Him to restore our lands. I do not care if you believe or not, just do it anyway, everyday, for the next three weeks. When enough of us do it, it will happen. If I am right, then yippee! If I am wrong, then you have lost nothing.
God...a failed hypothesis.
Well that was three weeks of my life spent well : NOT praying.
Well, Jon Summers, did you really expect the climate change to snap back instantly? If it was to do so there very well could be serious ramifications involved. Jim Keller, Jesus is not a hypothesis. Just because you cannot see Him does not make Him any less real. Be sure to tell Him when you finally meet Him that he is just a hypothesis.
Dear God, please instantly make the climate snap back. ThanksThanksThanks. (God being a invisible unitritheothingy that answers magic prayers)
Well I prayed a whole minute to something somewhere (probably a zombie jew) and the climate remains changing to hell on earth. So I guess that proves that God exists because why?
