- Can high-tech solutions help protect the climate? What would be the side effects of further human intervention in nature?
Attempts are being made to reduce the CO2 in the atmosphere with technical solutions. For example, new carbon capture technology that can extract CO2 from air and water, even if the amount currently captured is minimal and not enough to prevent the climate crisis and its consequences.
Still, there is no shortage of ideas. Adding basalt rock dust to agricultural fields not only binds carbon dioxide but keeps the soil fertile. Biochar, made from organic waste, has a similar effect.
Some ideas are bolder: A protective screen of particles in the upper layers of the atmosphere could filter sunlight, as seen with the eruption of the Pinatubo volcano in the Philippines in 1991. The millions of tons of sulfur dioxide spewed into the stratosphere cooled the earth significantly.
Theoretically, aircraft could be used to deliver the particles. But experts warn that the consequences for humans and the weather would be felt worldwide and could never be fully controlled.

Green fencing with real leaves , in cities , could be an easy way to lower temperatures. And they don't need much space , being mostly vertical.
Often trees damages buildings. Would love to see green roofs instead and some roof with is strong enough to grow food too would be great
we've knowned about climate change for decades at this point. What we must do is reduce consumption and yet it increases each year.
And think about work also. I work in a textile company. With less consumption more coworkers are without income. We need solutions here also. Some smart people also tell me that we can find job as a nurse in a retirement home. But I was helping old people in the past but it made me depresst and sad.
yeah and thats okay. all we need to do is suck the co2 out of the air.
if you do not want people to consume more then you want them to be poor. you want them to live in poverty. the solution is abundance and reuse
Yup reducing consumption is fine, but there is more that we need to consider! ☝️
@@MarcPagan What you said is taken out of context. Plants, the soil and the ocean absorb approximately the same amount of CO2 that they emit on a yearly basis. This is why when vegan extremists claim that cows are the biggest cause of climate change, they are factually wrong because surface CO2 and methane generated from plants and animals themselves is irrelevant to the calculation (which doesn't mean that we do however consume too much meat which causes deforestation and the need of tons of artificial fertilizers and pesticides, but that's another topic).
However, humans take carbon and methane that was stored under the ground during millions of years (under the form of fossil fuels) and we burn it. This increases the concentration of CO2 and methane in the atmosphere. Even if it only represents 2% of CO2, this increase in concentration on a global scale is actually massive and it's getting worse every year and has a real impact on our climate.
DW's documentary series regarding climate change is commendable👏.
giant CO2 vacuum cleaners are a fossil fuel ploy... that fact that DW showcases it shows they are part of the problem... Do better DW
Did anyone warn you climate criminals are committing env and human rights atrocities acts of ecocide? And the campaign to prosecute them under the mandate of the international Criminal Court ? Ref Stop Ecocide International
We need less cars, less cruise ships, less chemical plants, and less private jets. We need more walkable cities, more trees, and more white(reflective surfaces)
We need less people, lower standards of living, less talk of health and happiness, and an overall goal of reduced human flourishing.
@@MalachiWhite-tw7hlwe are not overpopulated contrary to what you may think.

@@MalachiWhite-tw7hl the rich get richer the poor get poorer its not gonna work
Would you consider adding less births to your list, why not nip the carbon problem in the bud, so to speak, less births naturally means less carbon emissions.
God, i love this channel. more please
Thanks for watching :)
Or how about we plant some more trees?
..oh wait. That doesn't make anyone obscenely rich.
And why not Go back to Hemp...
Stop nuclear power companies. U know what who even cares all a lie
@@jsaintr.i.r4018 We should be building more homes with bamboo, hemp, and wood especially in earthquake zones like Turkiye. Hempcrete walls are breathable with high insulation qualities and can lock up carbon for hundreds of years.
If you're the people who grow the seedlings people buy to plant, you can become "obscenely rich".
As they said at the beginning of the video, there's lots of different ways to get to the same goal.
Yes people will make money, out of it.
YOU could be one of those people IF you want to be one.
@@jimthain8777 I was referring to various companies that are milking government funds for "re-inventing warm water". The "revolutionary" world saving technologies, when it is so obvious the simplest things can make the biggest impact.
Out of all these amazing technology, we need to plant more trees all around the world and reduce the emissions, as soon as we can.
Amazing Documentary❤️❤️❤️
Also carbon is a good building material, burying it seems wasteful and ironic considering we use too much cement that releases carbon into the atmosphere.
Concrete is a heavy carbon luxury. If one gathered all the concrete companies in the world and labeled them as a country, it would be the third highest carbon producer in the world.
Do you know where your concrete ingredients come from and how it is mined and shipped.
DW needs to report how much CO2 these guys are reducing.
They are very neat tech, but quantitatively isn't it just a drop in the ocean?
Nothing will get better with these effort sadly.
its early days in research
For now, it’s experimental. But what is learned from the experiments can be scaled. Remember, at one point there was only a single car in the world.
Thank you for this interesting and very important documentary. Let's all work together to save the climate !
Thank you for watching and taking the time to comment!
Another ultra wonderful scientific journalist doing shared by (DW) documentary channel ...thank you for sharing...
Our most advanced technology is the human mind. We should be doing less, learning how to control our destructive desires, and restructuring everything to promote ecosystem health.
No that was true but the human mind is now second to AI and within 5 years by orders of magnitude we will be left behind. The estimate for AI IQ in five years is 1,600 compared to our average of 100. AI will solve this not humans.
there is no money in that so it will not happen. dont worry capitalists will harvest billions trying to figure out carbon capture before they give up
yeah doing less is about where things are, Did you mean to write MORE ? where are these destructive desires?
Australia is helping by opening new coalmines and gas fields. Kudos Tanya Pliversek!
LMAO!🤣🤣
Exactly, Australia selling most of its coal to china, china does more damage than all the countries combined and thinks if the rest of the world does most of the work they will get clean air. China last summer reached 50 Celsius,people there suffer in the warm months.
"With its large land mass and long coastline, China has exceptional wind power resources: it is estimated China has about 2,380 gigawatts (GW) of exploitable capacity on land and 200GW on the sea." China is accelerating its move to renewables. ""Solar power generation over the years has increased exponentially, reaching 330 TWh as of 2021. Wind power is the second most crucial renewable energy for China ."
Not true! China is creating more green energy, yes, but at the same time adding much more coal energy. That’s why their carbon output is still massively increasing.
Australia is huge they have lots of forest ( carbon storage ) . Probably Australia needs more reforestation
Thanks for posting.
Wow basalt rock . What is the name country to take its?
The promise of a technological solution is often an excuse to avoid taking the difficult and unpleasant actions that are really needed. No need to sacrifice economic growth and the comfort of our unsustainable lifestyles, when you can just promise that some scientists will invent a problem-solving miracle in the future.
The proposal for sulfur powder shielding has the obvious drawbacks of the potential for fallow farming or lower evaporation.
The problems faced have emerged from chronically elevated CO2 concentrations.
Perhaps other measures should be approached.
I’m more concerned about the creation of sulfur dioxide or sulfuric acid..hydrogen sulfide etc. in the atmosphere.
There can be no solutions without, at the same time, a lowering of energy and material consumption
How it will happen if we reach 11 billions in 2100 ?
@17:11 in the water to the right of the pilon (below the red square on the bridge).....lol, what breaks the water surface??!! Thank you for the video, very educational, and appreciated!
I think it is a pelican that is having himself a fun little swim. Looks like a wing.
I wish we had an automotive cabin air filter and engine air filter that could sequester carbon. The total accumulated volume of air processed through vehicles could be substantial.
Would it be as much as the carbon required to make it and run it in the first place I wonder? Maybe work from home and not drive at all or build business communities close together that you can bike around.
1000 years from now Federation Diplomatic Science will observe and assist such processes on many various Klingon planetoids. ❤
absolutely brilliant
Good job keep it up❤ 🌴🌲🌳
Alge is one of those good solutions, plus it could also be used to be turned into bio fuel or synthetic fuels for cars or be used as other things
No it's not. The energy returned on energy invested for biofuels is abysmal. Try doing some actual research.
Why does TH-cam put up a "Context" link at the top page of the video?
Excellent. Keep up the good work
Thanks for watching!
It calls for concerted effort from everyone involved
And need more energy.
Just plant trees
Absorbing co2
Absorbing water
Keep the soil cooler.
Thank you for sharing these worthy initiatives. Climate change is a collective issue. Nature is intrinsically connected. Humankind cannot survive as a bunch of 7 or 8 billion individuals. We can only survive interdependently. Now we need some 4 billion people like you to take actions that would enable nature to start recovering. What we need is a persuasive and convincing consumption alternative. The one common incentive that I could think of is money. Virtually every person on this planet would be willing to adopt change if they get money for it. And all over the world money is governed by administrations. If we could persuade a sufficient number of administrations to agree on ways to compensate people for their change of consumption of products energized by fossil fuel, to products created by alternative energy sources, with money, we could reverse the climate digression.
I am hopeful. Alex Goslar
It is so bad that all the people in power that are warning you about it have beach houses and fly around in private jets. For 50 years I have heard this or that was going to kill us in twenty years, still here. Yet nobody talks about the pole shift or the core slowing/stopping.Millions of people in poor countries would die if there was a sudden stop of fossil fuels. The planet has gone through billions of years of problems. As George Carlin said, " The planet will be fine, it's humans that are fd.!" Humans going extinct is inevitable whether you like it or not.
Unfortunately the governments get their money (tax) from the people purchasing or making the products. I’m wracking my brain but I can’t see how a money/sales based economy can ever be sustainable with respect to the environment. Perhaps the shift we need is bigger.
@@davidcooper5790 I believe those with means need to deeply understand what the seven sociopathic pillars of capitalism are, in order to create the changes needed.
@@paul9156c could you list those for us?
Sometimes the thought doesn't count and in the case of every single technology discussed in this video, it's too little, too late. Nature does need to recover but there's far more too that process than meets the eye, and the bulk of the "nature" that needs to recover was in the soil we dug up to grow our food, serve as the foundations for our buildings, and build our infrastructure.
The Rhizosphere is the foundation of all terrestrial life, and of the Carbon Cycle. Within it lies the bulk of all terrestrial biomass, the majority of all natural carbon storage potential available now, as apposed to hundreds of years from now when any of these technologies might theoretically (if built by machines and AI) begin to have an impact on global CO2 levels in the atmosphere.
Life is Carbon. The Rhizosphere is the single largest vessel of Life open to human manipulation, and only requires that we process and distribute a quarter of our organic waste per year to millions of acres of diminished land. Within 50 years this process, which would cost essentially nothing if deployed properly as a career for the unskilled laborer, can and absolutely will have a statistically significant impact on global CO2 levels. And that's just if adopted in North America.
If around 5 million people per continent were actively employed in the process of spreading organic waste over diminished land, not only would the GDP of every participant nation go up, but it would solve the river of problems being literally leeched down stream by the catastrophic failure of Industrial Agriculture.
This Carbon Crisis is an opportunity to put all global societies back on a path of ecological, social, and economic equilibrium. We simply have to put a few million dirt farmers to work doing what Industrial processes can never properly synthesize. Dirt Farming.
Excellent, you guys are doing extraordinary activities and allowing us to see a more hopeful view of the world and ecosystems.
Est ce que la vision optimiste que vous avez signifie que vous espérez que nous pourront continuer de « profiter »sans restriction comme à présent de notre mode actuel de confort?

Great ideas, but is it neccessary for humans to create problems via anthropogenic activities in order to enhance our technological advancements to tackle the same problems?. Am not saying that to advance technology is an issue per se, but we would not be able to catch up with rate at which we emitt CO2 in the long-run. Thank you DW for amazing documentaries like this.
Thanks for watching and sharing you thoughts!
Thanks for a very informative and interesting documentary!
Smart ideas won't do much. Changing societies will. Plant trees wherever possible. Rinse, and repeat.
The algae project for the consumption of the C02 includes the heat. Certainly heat has a function as well as a format all it's own. This is the action of Fire in Nature.
How does the carbon released in mining, crushing and spreading powdered basalt compare with the carbon the dust later absorbs?
Yes, this.
The air filter reminds me of an episode of sea quest
All these technologies are great, of course, but we need to approach more thoroughly what is the cause of growth, in short, our way of life and consumption, it needs to be changed and preferably radically, from construction, industry to everyday life.
What about Industrial Hemp?
how much fossil fuel is used to come up with ways to stop using fossil fuel
Less than the 115.000.000 barrels we burn every day.
Stories are very aggressive but subtitle English may also be included please for understable ideas
Maybe focus on real doable solutions now, like stopping the deforestation of the Amazon forest and other equatorial forests.
How is that doable though, if you don't own the land and you're not on the ground with machine guns to shoot the poor people that are trying to make a living selling lumber and growing crops?
We should build white platforms in the Arctic to reflect the sunlight. They would be embedded in the ocean floor and over the time the ice would reform around them. If it is possible to place them in the atmosphere as well than that should also be done.
Lol, are you five years old? Embedded in the ocean floor? That might be the dumbest thing I've ever heard 😂
Avec quelle matière et quelle énergie?
yes we need to invest first
We should implement new solutions to climate but the government has a major role to play
I wish this is brought to my country so that we participate also to help our world.
We need to use fugi and liverwort, to make big panels that can be stacked, the diffent types of fugi will do all the work, you can connect the panels with the funige with will create one big bio structure working together, it will have more co2 surface area than a tree, and the panels can be placed on roofs, you can then either use a diffrent fugi to deposit the co2 into the ground, or save it and make bio flue, it you can incorporate this into a indoor super farm, then we can both carbon capture and produce food in the same space
I’ve learn in petroleum engineering we can use CO2 for EOR injection process to reduce oil density in the oil reservoir, but compare to water injection the CO2 are more expensive, hope the CO2 capture technology are getting reliable to use in the future.
there was a start-up on one of the american continents which released sulfur particles and was selling 'credits' last year i seem to recall. they got shut down i believe. It was however very small scale and wasnt in operation for any length of time
Honest question......is the quantity of co2 we exhale as humans miniscule in comparision to the burning of fossil fuels and wouldn't planting more vegetation be an easier fix to the problem seeing as platns absorb same naturally.....again, honest question.
I especially like the algae solution.
Why not farm it in the sea and then scoop it all out. No need to use land area at all.
@badrinair I think you need a controlled enviroment to make them more effective and to avoid algae uncontrolled growth and hence environmental problems. But there are many suitable spots on land! Problem is cost of infrastructure vs effectiveness.
For the same reason we don't dig ditches by hand. It doesn't make economic sense.
Even if these are long shots, it does my mental health a world of good to see climate solutions. The doom and gloom stuff, while important, is painful.
the doom and gloof stuff is also fake.
For a simple idea of mine
Grind it up with live stock end trails to decrease the dust trails
to control all the technology to move... energy or fuel or electricity is needed, and it needs to be obtained from something.... and to maintain all this equipment, how many resources are needed....
The final message was the most important. We have to reduce drastically the emissions. That will cost much less. Actually will bring a lot of savings
No.
I am glad to help you out.
#1 It's not the planet itself that's in danger... Just the fragile things that live there currently. Eventually we're all dust in the wind, so it only matters to life, not the planet.
Powdered rock sounds like a silicosis risk. It would be safer to make it into pellets before using.
keep hope'n
Hank Greene talked about cloud seeding and that using sulfur is a very bad idea. Another project sprays sea water into the air to form "clouds " which is just as promising
Younger people are pissed and we WILL fight for our future. This video gave me hope.
While innovative solutions are essential, a balanced approach that considers potential side effects and long-term sustainability is crucial. Collaboration, research, and cautious implementation will play key roles in our fight against climate change, ensuring a better world for future generations.
Sulphur in the atmosphere is the dumbest idea I have ever heard, reduces temperature, but also food production... globally... Not to mention if a major volcanic eruption decides to tip us into multiple years of extreme winters...
They are researching if acid is bad for lifeforms at 19:00?
Sulphur + water. Omg how bad could it get?
Hmm, firstly a set of loosely arranged agreements must be fell upon.
This way, as the active mind is successfully kulled then how to activate the gathering? These agreements must be based upon sustenance and progress. This list must be small in number; list of agreements.
Smart ideas can of course save the planet. However, the main thrusts would have to be nature based.
Natural measures have 4 times the impact of human made moves.
So, centering on greenery, plantings, afforestation, water retention, desalination, and healthful soil practices are paramount.
Collaboration on an unprecedented scale would also have to be seen.
The technical factors and implementations are as pragmatic as they are lucrative. Technical portfolios are merely upgrades, all tolled.
Saying that solutions have to be "nature based" to be the most effective is not necessarily true. They need to be SCIENCE based, whether that means natural or artificial, most likely both.
btw; the planet doesn't need saving. It's some of THE LIFE on the planet that is in danger.
the planet could never remove all of the carbon we've produce, it wont magically vanish, it needs to be artificially shoved under ground forever,
trees only store it temporairily, but they all die.
if they don't say Rhizosphere they aren't selling solutions, that's all there really is to it. Can't fix the carbon cycle without rebuilding the global Rhizosphere, so if that ain't the first thing out of somebody's mouth, they don't have a solution. They have a motive.
Science takes its cues from nature. @@theobserver9131
@2:37 Carbon dioxide is NOT a harmful gas. It is a colorless, odorless, non-toxic gas that is an absolutely essential building block for all life on the surface of the Earth.
Let the market decide.
10:56 it generates acid rain ? Will it generate sulfuric acid in the rain?
It will enhance the acidification of the ocean?
If you want to reduce/remove CO2 from the atmosphere quickly? Reverse desertification! Unfortunately I doubt that much money can be made in doing this, so it’s unlikely that businesses will bother!
sounds like the beginning story of SnowPiercer hehe
The summary of climate change is easy.
It is the change of humidity in atmosphere, which produce between the (land)and the(seas & oceans) on the other hand...
Occurring of rains, snow, storms, and floods at time and in unexpected places, confirm my theory(the change in the directions of winds)which must be balanced...
How to reduce the heat of the earth and atmosphere?
We must supply the earth with a natural cooling places...
Results:
----------
1- To balance the water vapor which produces between the( ground)and the(seas and oceans )...
2- To balance the pressures of the air in the atmosphere...
3- To balance the directions of winds which caused the climate change...
4- To control upon the storms and harricans...
5- To revive the the first theory of climate change (dynamic horizontal movement).
6- To balance the percentage of gases forming the atmosphere.
NOTE :The lack of water vapor is of land not of seas and oceans...
These studies had completed and sent on July 26th 2000...

Grate.I hope more solutions like this.
Basically this kulling is important, because. There does exist a small, quite small(rare) group of Noble Natural Gasses. If the injection of these gasses into the atmosphere is approved without the proper scenario becoming abducted , ahead of schedule or poorly planned this could be a disaster! Because there is basically only one single injection packet large enough to have the effect of some lasting standard
Human Beings still haven't learned how to leave things alone. They repeatedly find out their ...Solutions become Mistakes become Solutions become Mistakes.....over and over again. We have an irresistible and obsessive need to tinker.......and eventually this screws up the balance of ANYTHING and EVERYTHING around us.
The problem of the problem is human beings. We are our own enemies. Leaning to self destruction and extinction.
I find it ‘interesting’ how Sunak has rolled back on his climate pledges in the face of so called climate change. Just confirms to me we are being lied to.
the real question is can we save our selves from politics. This Climate business is only about politics and it is hurting everyone else.
Interesting. I had thought when they started to talk about capturing the CO2 that they would reuse it to burn/heat something. Instead it is being put into the ground, filling up the holes. Does this mean the filling up of holes will cause long term flooding and the ground will no longer be porous?
Burning hump can repair the ozone layer
This problem is self-rectifying. If a couple of billion humans die off, resource demand will fall off and further GHG emissions will fall, and the human species just might survive …
Faster!
No. We are way past any of these "solutions".
These people need way more budget (>10x) to do some scale -up tests ! Take it away from war&space nonsense so we might win this battle.
I always wondered why don't we create algae plants at coal/oil/gas plants to extract the CO2 at their exhausts. We can then use the algae as bio-oil, alternative plastics etc etc. The excess we pump back into depleted oil fields
Because it's not commercially viable. You could do that, yes - but it would take a lot of land area, a lot of maintenance, a lot of nutrient feedstock. Biodiesel would flow from the outlet, but you wouldn't be able to sell it because regular diesel is cheaper to refine.
International collaboration stands as a linchpin; nations must forge partnerships, sharing knowledge and resources to collectively confront the shared challenge of climate change on a global scale.
You can’t solve fundamental problems with technical solutions.
These people all ignore the Milankovitch Cycles when discussing climate change.
Look at Dubai. No messing around with weather!

Did anyone else see the funny fish at 17:12? 😂
I respectfully question the claim that the biochar machine produces zero emissions. Nothing in the video is showing how the smoke particles, NOx, SOx, CO, and CO2 are converted from gas to liquid or solid phase...if they are truly containing all emissions, then would it be more completely truthful to show how...or else clarify the zero emissions claim in the video?
Why not go to the root of the problem and tackle that, rather then find solutions to side effects!
Too little too late.... Much better now to invest our efforts into finding ways to lessen the suffering that will ensue from the disasters that we have already initiated.
The filters have PFAS which harm our environment
So much this never stops
Geoengineering is a solution with an extremely long lever; artificially cooling the planet whilst emitting a consistent amount of CO2 into the atmosphere will lead to greater 'carbonization' of the oceans -- accelerating their acidification further. We can do it -- we just need to be *extremely* careful with it. One step forward, two steps back; we fail fast and learn from our mistakes then we make more mistakes -- this is the human condition.
Geoengeneering is going on for at least 15 years. Only in the last 2-3 years it got worse. Can't you see the chemtrails in the US, Canada, Europe, Australia? Creating bad wether almost on a daily basis? No sunshine and that metallic sky with chemical layer of artificial clouds like mass? The climate is being changed, so the world government can enact more taxes and destroy crops and nature. This is the real pollution and evil. There is nothing wrong with the Earth and climate. It is the weather modification program.
Nature makes changes over billions of years and now we need to do something in 50 years. What do I not understand?
Space industry needs to be designed for bring on from planet to the earth. Likewise, gold and silver and titanium and others also gaasoline😢
Fun fact: in pinatubo eruption is not hundreads of death it's thousand
Hard to take out seriously when you lived past the end of the world expert predictions so many times.
Some filter on a exhaust source in India China. Prevent dark FPM from entering the wind and prevent FPM from travelling to icebergs
It's great to see companies trying combat the CO2 problem with tech however, as the last scientist said, "why not stop emitting CO2 in the first place" We do have a definite solution, just no one wants to be responsible for it.
