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?

  • sooo we're going to spend trillions of dollars for years to slow climate change just so we dont have to abolish capitalism?

  • 자막추가점여 ㅠㅠ

  • didn't the Animatrix tell us why spaying gas to block the sun was a horrible idea?

  • Isn’t this the plot of Snowpiercer?

  • What do plants breathe, CO2 what do we create? a ton of it. The world is actually greening and getting a looooooot better. Now I can't help with the warming problem but the plants are loving it. The only real thing I can see being a problem with warming honestly is Antarctica melting but honestly, we shouldn't be too worried. It's nature nothing we will do will change it. We can try to prolong It but eventually, we’ll get wiped out by something we need to be learning how to adapt to the coming harsh weathers and environments not fearing them. Life will go one we can't change that. This is the way the world has been for millions of years. This will probably anger people. I'm very willing to have a calm debate and learn more but I don't feel like getting yelled at if you do comment.

  • bUt FarMs NEed sUNlIGHT :(

  • We could saturate the solution and attempt to crystallize it out

  • Farting plane.

  • World: Is gonna end and we have to take a risky strategy. Kurzgesagt: Oh no Anyway this video is sponsored by Brilliant Edited: *Not Hater*

    • but... you didnt edit the comment

  • Look, dear kurgeast, I will not learn English just for this video. Just give Turkish subtitles I don't want that much

    • NOTE: I am writing all of these with the support of English translation.

  • 5:02 Ngl scientists made a smart move there

  • I actually just learned something my teachers are failing to teach me thank you

  • There is something i dont understand... why does he first say. That we need to stop rapid climate change. But then at 7:20 he say that we try to see how fast we can heat op earth😐

  • And everyone ignores the safest and most reliable renewable source of energy:nuclear.

  • "And this experiment Is about to get really exciting" Indeed, fellow people

  • We do not have to worry about these climatic changes. More than likely a large volcano will inject the dust required to chill the climate. There is the possibility it will chill the globe a bit too much and we will be selling snow shovels in Arabia. Maybe we just accept the heating and work on ways to mitigate the adverse effects.

  • Try it over Turkey or Russia and see how that goes.

  • But warmer means wetter, not drier.

    • @GaryOak yes, and a temporary dry spell helped precipitate the civil war in Syria, and the fluctuations at the start and end of the last ice age show decades-long drops in plant cover. What's fine at the scale of a few centuries can be catastrophic at the scale of the next harvest.

    • @William Chamberlain Global warming may be a problem for the equilibrium, but warmer times on earth have also been the ones with the highest fertility Preliminary results from a Smithsonian Institution project led by Scott Wing and Brian Huber, showing Earth's average surface temperature over the past 500 million years. For most of the time, global temperatures appear to have been too warm (red portions of line) for persistent polar ice caps. The most recent 50 million years are an exception.

    • Depends where you are. Should mean more moisture bin the atmosphere overall, but can change wind patterns, cause El Nino, cause monsoons to fail, stop tropical troughs from forming...

  • Isn't meddling with nature what got us in so much mess in the first place?

    • @Neo Smith set another fire so you can stand on the just-burnt bit and not get burned when the unburnt bit burns.

    • 💀 If you love something, set it on fire

    • Could be we've got to the point of needing backburning

  • Le Transperceneige....

  • can kursegagt be trusted

  • can kusegagt be trutsted?

  • Airplane spraying chemicals. Conspiracy theorists: .....O_0

  • And not a mention of Chemtrails in the whole video!?!? How can you talk about something and not mention it at all? Diabolically fascinating world we have created with our stories.

  • Every time I watch Kurzgesagt video that related to science, I can't help from feeling useless knowing I contribute nothing to the society to prevent any possible earth damages. Let me just vanish into thin air....

  • even if the whole thing worked and we lived out the acid rain,, the effects from whats above the acid would just kill us

  • i dont want to live on a train😭

  • Maybe we could Geoengineer naturally with those crazy brown & green CO2 scrubbers. I think they are called trees or plants.

  • looks like we already done it wrong. from safe weather 20 yrs ago to a city get destroyed everytime it rains now...

  • errrrr, have already been doing for decades - it is no secret

  • warming oceans have nothing to do with less fish.... it is the over fishing, geoengineering is great idea, but just using the planet not killing is sufficient for us to survive, but who cares planet does not need us for anything ...

  • by the way, the writing on the bottom or whatever is about random stuff 6:53

  • horribly dangerous ideas that encourage the continuation of our destructive system. . yep these are gonna happen.

    • @TheAdvertisement "Destructive system" shows me that he cares not for society nor having a normal life. These shut-offs only bitch and whine and have no life.

    • @If Only We could Lmao how is he a crybaby.

    • Do you need a diaper change crybaby?

  • Perhaps they're already doing it.. the conspiracy theorists were right. No more delaying the inevitable switch for profit... Carbon tax now. Fusion now. Renewables now. Easy. Also carbon capture is shit. Plant trees, save the plankton, save our nature reserves, rewild, cut out animal agriculture.

  • am i the only one who thinks that the house at beginning looks like coopers house from interstellar

  • I love this video🥰

  • After reading the latest comments, I have concluded that humanity won't survive for much longer.

    • @MineBlown nice, but I was talking about the people who think climate change is fake, or maybe you are those people.

  • I think you need to look at different political parts of climate change and not just say if awful and we’re gonna die in 50 years

  • LMAO!

  • 7:40 When the crew mates have ejected only other crew mates and there’s 4 crew mates and 2 imposters “We screwed up it’s time to call emergency meeting“ “Green was not an imposter”

  • Outro: *quack*

  • ✈️✈️☣️☢️⚠️✈️✈️😭

  • Funny thing because this is happening in the reverse

  • For those who still don't have the subtitles in their language. You can select a subtitle from another language, leave the transcription open (by clicking "..." next to the save option) and then apply Google Translate 😉

  • Geo-engineering is the main plot point of Geostorm, where humankind successfully controls climate all around the world, using a special Satellite network, until something goes wrong, threatening to start a Geostorm. You should watch it.

  • Climate change isn’t real lmao

    • You could say that in 2003-2005 and get away with it, because there was hardly any concrete evidence. Ice melts all the time they said, but in the last 10 years lakes have been receding and ice stayed melted.

  • who 's idea is dis

  • I always watched you and my family calls me "big brain" lol

  • Carinho pelos fãs brasileiros por favor ;-;


  • Basing videos on false assumptions is a good way to lose subscribers. Allow me to demonstrate by unsubscribing...

    • at least the percentage of idiots out of the total people subscribed had lowered.

  • Pretty despicable video here. Wow. We better fix the “hole in the ozone layer” first. Wow

  • Maybe politicians could effectively address climate change if they weren’t politicians. Politicians suck.

  • Русский перевод пожалуйста!!

  • there's a movie called "snowpiercer" and in the movie people did the exact same thing in this video and it went wrong then the whole planet froze to death

  • Windmills and solar panels aren't gonna be all that great and that may be why switching away is so hard Especially if we're trying to _block_ the sun, the effort into getting any solar energy would get much higher If you want an alternate source of energy that is both relatively eco-friendly and is incredibly effective I would advise nuclear energy, we already have weapons made of nuclear materials And once we start getting into fusion reactors and thorium all our power problems will be but a fever dream And there will be no more giant fields of windmills and solar panels taking up the land that could've been used for farming or left to the wildlife (thus more eco-friendly) When all you need is one comparatively small facility

    • They recently did a video talking about nuclear energy on their german channel, I can send you the link if you want

  • No legends

  • Sounds like a terrible idea

  • 7:24 The music is so good, it is calm and soothing but has a certain tension

  • 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.

    • Nuclear is the best by far in all categories. The waste produced by modern reactors is extremely small in quantity; better than burying millions of turbnine blades and old silicon panels in teh desert. The death toll is far less: especially less than wind power, which kills more utitlity workers per watt than any other.. oh and it works when the sun goes down and the wind is low.

  • Good video

  • What if we use Co2 for energy?

    • @Prime Royal So is your mom

    • @If Only We could The reason to use liquid nitrogen is that it is efficient and cheaper in the industrial scale.

    • @Prime Royal Wrong, liquid nitrogen is a lot harder to produce, CO2 becomes a liquid at a very cold temperature and a lot can be obtained into blocks which last for 35 minutes at room temp, whereas liquid nitrogen quickly evaporates and is much harder to condense.

    • @If Only We could Dry ice making process is energy-intensive. Besides, liwuid nitrogen is much cheaper and efficient than dry ice. Also because of the liquid state, liquid nitrogen can be used in ALL machines, as opposed to solid dry ice.

    • @Prime Royal CO2 can just be extracted and turned into dry ice for other futuristic machines to use.

  • 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

    • You mean those newfangled... waht are they called? TREES?

  • 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 space/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?
