By the end of the 21st century, humanity is becoming desperate. Decades of heatwaves and droughts have led to unusually poor harvests, while the warming oceans yield fewer fish each year. In the tropical zones, millions suffer from famine and resource wars have made millions more flee to the north. As things quickly get worse, in an act of desperation, the world's governments decide to enact an emergency plan...
It is far from certain that a grim scenario like this will play out. But the failure of world leaders to effectively address climate change, makes it far from impossible.
So in the near future it might become necessary to try something radical to slow down rapid climate change: Geoengineering. Interventions so massive in scale that they might undo centuries of human behavior. Or make everything much worse.
What is geoengineering, is it really an option and what if it goes wrong?

  • First, can we appreciate the beauty of the volcanic eruption animation? Second, can we please test this in Kuwait first! It's passing 50 degrees celcius in summer!

  • Anything is better than nothing, why are we not doing anything big already

  • Mt Pinatubo was from Philippines

  • It sounds like another disaster to be created by short sighted leaders.... Why can we just do things properly, and stop trying to cut corners so much. No amount of technology is enough to counter human stupidity.

  • Really?!! Nothing new here. It is and has been happening for while now. You see it in sky almost daily all around the world and it matches all the patents for it. It is one the largest contributors to climate change.

  • only 3 reasons i watch this; animation, education, AND HIS DAMN VOICE

  • What will happpen to The plants they will die with no sun

  • Dear pinheads, this is all ready happening, for a long time now.

  • Do a video on nuclear vs solar and wind energy. I’m particularly interested in their environmental impact rather than economic viability.

  • Good video

  • What if we use Co2 for energy?

  • No Arabic translation 😓

  • I dare you to watch all the Kursgesat videos (trust me, you will have a big brain after)

  • That sky gas thing->Animatrix vibes.

  • Some parts from this reminds me of Animatrix, where they blocked off the sun becoz they believed *those robots get energy from the sun" And the line "Thus the man become architect of his own demise" from the film.

  • Am I the only one who is seriously baffled that there are people considering this? I guess the only thing that surpasses human stupidity is it's hubris.

  • Please turkısh subtitle!!!!!

  • Stop propagating globo-bolshevik scams.

  • Its solar system warming and not exclusively here on earth. If thats the case why do we need to poison the earth and teraform our environment then? Do you homework and stop helping the agenda

  • Geo engineering “we might have to do”? They don’t have to do it and They have been doing it for over 50 years. You dummies are just trying to normalize it for the general, oblivious, willfully ignorant public.

  • Sub indonya mana gan

  • At least I will be dead by then

  • Imagine, all of humanity, trapped in a spaceship. The engineers and scientists have discovered something drastic: this spaceship is on a direct collision course with a massive planet, albeit in the far future. However, turning the ship is hard: it needs a lot of pilots and captains to do it, and it might take years. But there is time, so they have two options: Either they try to steer the spaceship away from the planet, which will take a lot of effort and money, and will require everyone on the ship to push on one side, but the scientists are confident this will work with less drastic measures and consequences than the second option: blowing up the planet. Sure, everyone might continue their usual life, but the risks are immense: the planet may not blow up, the explosion may even fling a part of it directly to the spaceship, damaging it even further. But it might work. Despite this, a lot of captains and pilots deny the planet approaches. Now, which solution will you choose? Reduce the CO2 in our lives to steer away from danger, or blow up the planet?

  • I wonder how many people's presentation were saved by this channel but that sure was the case for me

  • I'll always say: Biofilters using the photosynthesis to trap the excess of carbon dioxide away of the atmosphere

  • plss vietsub vid

  • Yeah. I'm gonna live in my car in the woods. Not only will I be doing better for the environment, but I can also disconnect myself from the BS that's constantly propagated on media. Besides, having anything more than what you need doesn't do anyone any good, not even you. Consuming a lot of expensive junk will never fulfill you

  • Hello

  • Hey could you please make more videos about technology like the dyson spear and the stellar engine?

  • Who else thought the plane was farting in the thumbnail?

    • If they can cool the planet, then I can live with more pollution! Yay!

  • Man, Alex Jones was right about everything lol

  • is this climate change?

  • Nuclear - the savior for our sins.

  • here comes the chemtrials conspies

  • OMG!! Absolutely the most ludicrous idea..... Ever. Do people actually believe this drivel?? SMH

  • So it's still a "conspiracy theory" - or is it now ok for us to talk about how we have been doing this for over 50 years?

  • To the 1% of people reading this, Jesus loves you. Take care and be safe.

  • They are already spraying us like bugs! Just look up! It does not take a genius to figure it out! Could, may, might my butt! They have been spraying us for decades!

  • I swear, if we resort to releasing sun blocking gas, people are gonna be crazy about chem trail theories.

  • This is like the backstory of The Matrix.

  • This is like geostorm movie trailer

  • This channel is pure brainwashing

  • Ainda não lançaram as legendas em Português 😢

    • Entendo sua dor.

  • There is so much marine life that is sensitive to even small amounts of iron!

  • The future is basically “Interstellar”

  • Thumbnail: plane fart

  • If they can cool the planet, then I can live with more pollution! Yay!

  • Would you consider to make a video on meditation? The science, not personal Experience (unless you have integrated it to Experience) A lot of the science is based on people’s experience and integrated with neuroscience. I think your (I know you are multiple peaople btw :) ) channel with a great meditation video could help a lot of people and the world. I’ve watched your greatful video Those combined are really strong (according to other people, I haven’t really focused consciously on being grateful. Meditetion need more objektivity and that’s done through science, you guys are in a great position to make a video on it Great day

    • Now why can't Alegria be this pleasant to look at?

  • let's not forget that this acid forming in the atmosphere will come raining back down again

    • Love this show, wake up early just to watch it ??

  • Türkish suptiters

  • Soooooo we're buggered then😮

  • I love videos about the world ending

  • We could actually make an international agreement to make a lot more white surfaces... It would be ratther cheap to change all asphault to concrete, paint all roofs white and make a lot of vertical gardens...

  • Capitalism is destroying the planet They don't want to stop using fossil fuels because it makes their pockets full with superprofits

  • “Oh no zone” That got me

  • Nice video, althought the wrong spinning direction at 6:40 hurt.

  • Love your content as usual, but on this occasion I do have a small criticism. Your comparison between the greenhouse effect and a duvet is, I think, misleading. With a blanket or duvet, you are attempting to disrupt convection, NOT radiation. The two are not really analogous.

  • 한국어 자막좀 제발ㅠㅠㅜㅜ

  • Yeah, next let's release Cane Toads into Australia and stop the native Cane Beetles destroying our crops. Nothing could go wrong with us interfering with the natural world's complex systems huh!

  • Could it be that there were martians and they did this?

  • Yeah, capitalism is destroying the planet, and it would use this technology as an excuse to make things even worse

  • Exiteing

  • sooo... should I do GeoEngineering instead of getting an undergraduate in Atmospheric science?

  • 4:53 this dude is doing science lmao

  • Now why can't Alegria be this pleasant to look at?

  • For some reason I thought the thumbnail was a whale as a plane and I was thinking of bio instead of geo when I saw it so I thought we were making fleshy planes


  • Snowpeircer. 1001 (994) Cars Long.

  • I love the new intro :)

  • predictions based on a model that is factually untrue, but this fantasy future sure sounds like a bad place.

  • People will just adapt the important thing is for the countries watch out for themselves and their people

  • Thank Thank

    • *OhFreaking*

    • Freaking awesome

  • *Well u should be happy thanksgiving*

    • Thank goodness for the imposter syndrome and the imposter syndrome

    • Do you wanna knowledge it

    • F***s

    • Hats Heckling

    • Childish flush

  • It will 10000% happen as you said. We cool the earth, goverments say "Look snow cold we no need stop fossile fule" and go on. OR even better with what is happening right now they'll pump artificial money into fossilfule comapies to keep them "alive"...

  • Bruh the plan in the thumbnail looks like its farting

    • I envy the people who created all these problems and will die blissfully without even having thought about solving them for a second.


    • I am so disappointed to the people in the comment section as they keep making jokes instead of making this become serious people is dumb accept it

  • Why are these horrible ideas?

  • I've heard people talk about using nuclear winters to slow global warming

  • Where is the hero who translate to Spanish aaaa

  • Boy, the chemtrails people are going to loooove this.

  • I loved the idea much better than ending the factories

  • Honesty this whole Climent change thing is SUPER over hyped I'm not denying it and I know we have to change the CO2 thing but this is bonkers risking the death of humanity because """"ClImeNt CAnG"""" is tarded I propose we switch to nuclear energy slowly and then switch away from nuclear to somthing better then oil and better and safer for nuclear

  • The climate has always changed and always will. Climate was never expected to be static. Get over it.

    • @Best around humans will be just fine. You literally just made that up.

    • Yes, but the difference is that this is man made climate change. It is far too fast for life to properly adapt. While life in general is will more than likely survive, anything close to our current way of life won't. If we stay on this path mass extinction is going to happen, and humans may be apart of those animals that get wiped out.

  • My god, the earth has been through so much chaos.. A few degrees change will never do anything the earth hasn't been through a million times. So those gasses they wanna put in the earth to keep the sun out is bs

  • "You probably won't have to do any of that yourself..." Me: Nope. I definitely won't. "...but who knows?" Me: PLEASE DON'T

  • D:

  • Technological innovations driven by short-term profits will never be a long-term solution for problems caused by infinite growth.

  • Lol we can barely get people to wear a mask, don't climate change will ever be solved

  • So yep, suffering encountered by Philippines on Mt. Pinatubo eruption, become an inspiration for a science project.

  • Why why why we need to interfere with nature. We are already doing enough damage. Let the nature heal itself.

  • I am so disappointed to the people in the comment section as they keep making jokes instead of making this become serious people is dumb accept it

  • I envy the people who created all these problems and will die blissfully without even having thought about solving them for a second.

  • If these clouds from the sulfer stuff is pink like that im cool with it.

  • I think it’s a bit narcissistic to think us humans can do natures work better than nature. If the world heats up and destroys humanity, nature will reach equilibrium alone. I mean earth was just a carbon ball of fire a billion years ago.

    • Humans can do things better than nature, idiot. That's why contemporary humans live decades longer than earlier humans. Who gives a fuck about whether nature will reach equilibrium after humans die off? What does nature matter if life isn't here?
