as long as miss alt strides on a residential building on the warehouse in the central ukrainian city of rivera killing, at least 10 people, it's fed, some people are still buried under the rubble of the capital cheese and the northeastern city. okay. well, so that's it from me on the news team. i'll have an update for you at the top of the hour. don't go away. close up is gab office for me and to these team here in billings. excellent. the really profiteering instead of responsible for the global business of s. festus this is not a legitimate business and the people that are in don't deserve to be treated with any kind of courtesy by the governments of the world. the never ending story of asbestos starts june 21st on dw

john c o 2 vacuum cleaners. miracle dust in the fields. algae farms in africa. hi. take efforts to stop global warming and say no, i'm 10 years from now. it's too late and we need to start now and research it from all angles. what is most effective effective, what can be implemented later? that's balls. which innovations can really mitigate the climate crisis and which ones should be used with caution? your condition, we can't take one problem or humans have created to add another on top. i find that very unappealing. i'm talk high tech innovations of breaking new ground. but can they really stop the climate change? the

a muscle and son is doing the rounds in his garden. in western, germany's ryan has the region. most of his plants have recovered from last, thomas heath way, 2015. as on the locked of the lawn which was exposed to the sun and turned into a field of stomach and the ssl, it looked nothing like a lawn anymore. it looked like it was in southern spain and it hadn't rained for 30 years. i'll think it was alarming elf grove, at one point we just stopped watering at the draft scratch was too much the consequences of climate change. a palpable buzz here in the garden and more dramatically elsewhere in the world. martha and spun believes that something has to change on a small, as well as the large scale maintenance. there's a wide range of solutions. there's no one answer and it's not just down to electronic ability or rain water management or giving up meet. there are so many constructive solutions that work well for you in the news, all will show us later which of these solutions he's involved in professionally of

the intensive research and the climate change mitigation has been conducted for several years. now in iceland, nature officer solution with an ideal combination of ingredients, geothermal energy, volcanic rock, and plenty of water. the like a spaceship, stranded in the middle of nowhere, the oil could call them catch up sound is the 1st of its kind. okay, use of dr. connect to is to filter carbon dioxide a harmful greenhouse gas from the atmosphere. the, the filter captures the c o 2 while releasing the cleaner air back into the atmosphere. and uh, once the filters are full, you close up the compartments that the filter is in. and you apply seats to uh,

around a 100 degrees celsius, which released as a c o 2 that we can capture and collect the heat is produced, renew, i believe from it to you to and will power station the old keeps on, has collected $4000.00 tons per year, so far, the equivalent of the greenhouse gas emissions of $360.00 people in germany. it's not a lot, i mean, because it mits, around $36000000.00 tons of c o 2 per year. but this is a new technology. we went from capturing milligrams, 2 kilograms, 2 tons to 4000 tons. and so we are on our way to a huge, massive scale of motion. so will be built soon. not just here and nice and wherever there is volcanic rock, these plans can be built as the c o 2 can be permanently stored in the wrong that's what's happening under these a glaze nearby the

all the way of tech to good not son explains to us exactly how the company he works for the event of the process. it's simple, at least in principle. so this allows 5, but we're looking at, there's a pipe from the jail, from a power plants injecting to a terminal water back in to, around 2 kilometers these 10 to the, to a panel area. and what conflicts to us is to actually borrow that pipe and injects our c o. 2 charged water coming to the smaller my into the bigger one. and also going down into the, or wherever the seo tool from the water is minute or less than in less than 2 years . it's a natural process, but it runs more quickly here as the quest as large quantities of c o 2. and so the question of the right ratio between pressure,

temperature and depth. what i'm holding here in my hands is to course a chill the before and the of the topics, not the one of them is the uh, 5 south figure. all that you can see it has a lot of homes in it. so the water that we inject into the ground goes through these holes. and the seo tool when the water and the solves metals in the rock and forms a mineral called co sites. and this core that i'm holding here shows you the white thoughts is c o 2 that has been turned into stone, filling up the holes in the rock. the c o 2 can stay in the rock for ever. several 100000000 tons of c o. 2 could be stored under this plan to loan and much more worldwide. in principle, it's

a brilliant process, says 12 and i'm on at the university of humbug. he's working on ideas to remove c o . 2 from the atmosphere. by side this most of my life, but of course you do have to ask yourself what it costs less costs with us, the all. and if there are other solutions that can make a contribution, which are perhaps less costly did uh oh. bypass by some kind of deflect, direct, the air carbon capture is one way. there's huge potential that's put in salus will at least in places where there is enough for cell trucks. i'm green energy. but is it really the way to stop trying to change? you can not use this technology to as an excuse for business, as you'll see a little bit can only be on a fission to all of our other efforts and reducing emissions, reducing that dependency on fossil fuels, changing over to green or sources of energy. we need to, to all of those things according to the un in together mental panel on climate

change, carbon dioxide emissions need to be reduced quickly and drastically to hold global warming to $1.00 degrees celsius of laid out in the 2015 power as climate agreement, but to ensure this existing greenhouse gases also have to be removed from the atlas van. this is known as negative emissions because needs to full below 0 current li, just 2 giga tons of carbon dioxide are extracted from the atmosphere to year, mainly through reforestation. a tiny fraction is extracted using technical methods according to one study. these would have to extract over $1300.00 times more by the middle of the century than they do now. so he's here to escape the size of the small size. that is now it's not work, it has to be done faster. and if we facilitate more research, of course it will go faster. but it's not all we need to inspect the right political guidelines are also necessary to specify which direction we don't on to

go is in which goal is we want to have a way to see the volume at home and is got an assignment also relies on a small scale technical solution, putting up umbrellas to protect against the heat. put in by what it cannot be and we have to umbrellas for the area where children playing boxes at 30 degrees in the shade with direct sunlight, the garden and face of south north. it's not very sensible to be there without shade one of us, i don't mean front of the stall as it goes to head is the idea of a giant power is sold to cool the whole sinus a crazy one are actually knows it's been around. so sometime in 1991, the peanut to the volcano erupted in the philippines. hundreds of people because it is all over the world have been studying ever since. the volcano ejected salsa gas into the stratosphere, where it reacted with oxygen to form tiny particles. this foamed man,

which reflected unblocked, the sun life creation, a kind of dry and shield like a parasol for the time it 4 months. temperatures were half a degree cooler than usual. it's okay. nose can do is quite calm. human special ed across could bring the salsa up to the stratosphere. technically, it is possible to create an artificial shield against the sense limits splunk institute for me to reality, and hemmed up as we searching how it could work. well, they can nemaia and his team are using data connected during volcanic eruptions. when we do, if we brought cell for into the atmosphere, it would be globally distributed in all directions by aircraft. it would affect everybody. this is exactly what makes it difficult to assess the impact and consequences ever since then. we have to see what the impact of

a saw for emission up there would be what kind of crime in effect, but it has to end on the maybe there'd be side effects we can't easily for a single categories upset, some kind of duty by to it could change rainy and dry seasons regionally with consequences for farm is. it's also not clear how much sulfur would be needed in the advocacy. just leave it up with an insight on i'm so far as a lifetime of about one year. so that means you would have to bring up large amounts continuously, or at least once, twice, 3 times a year, to get a fairly constant layer on the federalized live. and if you stopped the whole thing, then with the software would be gone again and 2 years at most and the earth temperatures would rise rapidly again, but it hasn't understand. no one has the dead to attempt such a technical intervention in the course of nature. that suitable at cross could be available in just a few. yes. for the i just know that should really only be used as a last resort. but if we don't reduce emissions, i think life on earth will become very difficult and sun reaching the success,

which could very well tip the public mood and favor of such methods. of course, this would mean creating another artificial solution on top of artificial climate change, which is not such a nice idea either on the whole state. it's not, there's no constraint of course to invest dr. nema within one to see a political framework put in place to regulate the deployment of self of world wide . the idea was sparked by volcanic eruption. volcanoes also happened to provide the rule materials for office solutions, which could permanent. today we may have c o 2 from the atmosphere. volcanic rock can be used as a greenhouse gas think not just in orthodontics, so the, and also bought in this book, the sold rock just as being spread across the field. the . it's an experiment to show that c o 2 can also be sequestered without specially

develop totally tech machines such as your model is still showing what we're doing here is accelerating a natural process and the weather ring of salacious rock happens around the globe all the time. you touched, attended in the weathering process. rainwater reacts with the minerals in the rock . the c o 2 becomes fixed and permanent, t boned within a salt as a decomposition product. the conditions in the arable sewing are ideal. the funny thing to do with fox and can be the plants that grow there and the micro organisms that live there, they produce c o 2, the c o 2 concentration in the soil is much higher than in the atmosphere and that accelerates the weather in process let's pull tests. that sounds simple enough, spot is requires more research on a gale cost is already struggling with $1.00 of the most amount of all of the

problems on his field. the machine is taking longer than expected to take fingers for this technology is actually designed for fertilizer for line. that's why too little is coming out as missing competition survey. but we just improvise and double back out there is less of the of how to draw, which is very fine and drawing creates a lot of as i go as far as i think you can see the effect of the neighbors failed to de briefing with the scientists, the method and the formulas still need some look. every field and every kind of soil is different. the grain size makes a difference to the final does not of a like mind. the finer we grind to the rock, the great of the surface area, you can cover that there are pros and cons of both ways. and if you have very finally ground material with very little moisture and you get a lot of dust when you distributed open picking but also putting on the production

of the material is also more expensive. which is why the research has one to use existing powdered rock, if possible. it can be found by the time since a line around inquiries. this would be cheaper and more efficient. another advantage is that enhanced weathering release has nutrients that improve the sewing . tobin almonds team at the university of hymn book is investigating exactly how much c, o 2 is captured in the process. the result, the method works and not in, in the power train as something it opens. it also works in the field. we have to assume that healy god and it's just more difficult to prove it doesn't come up. and of course of field is not in close like a bucket or a tube or a huge rain barrel used for an experiment that kind of these things. it's open in all directions on up words downwards to all sides. so it's hard to really trace where the products of our weathering ended up at the home are they still stuck in

the ground? or maybe we can't recognize them at 1st and what we spot them again later. that's the challenge as well as photo dr. i'm on is sure to book and keep catching up to 5 percent of the c o. 2 emitted annually worldwide. the infrastructure already exists and there was plenty of arable land. all about this, even more ocean. the ocean is already excelled around the corner of the carbon dioxide emissions. and research has things to real. second might be much high. and the problem is that when c o 2 dissolves in bullshit, it turns into acid with tom's, both animals and plants, the carbon dioxide would have to become an increase requested in the ocean and acidity levels need to be reduced. an experiment is coming to being prepared at the g o more ocean research center into measuring pro,

so installed in these simple boxes, which are filled with soil. and ppos was only a guy not. and her research team called these boxes been to cousins, doors own. we have managed to bring the c bed to the tour and how to go who works there by filling these spend through customs with settlement from the politics, the important fjord watcher over it. we can simulate the see bit of the baltic scene and via the meals portal and also the guidance and hit team have retrieved, settlement from the c bed in various the locations these payments are now being done in the bend. so customs without any risk to the environment, rock dust will be added to the water as soon in different grain sizes and ratios. have come to mind taking the silica or carbon at reno, nevada, when they dissolve the marine chemistry, the chemistry of the see water surely is changed in

a way that means more c o 2 can be absorbed. so it's, i also know madam, come a welcome side effect is that it also neutralize is harmful acidity. in the most sense, these processes can be precisely measure it for seen as on. we have different probes that we insert into the settlement itself and some that we measure at the surface. so we can determine exactly how the chemistry changes that system and how the organisms in victoria and the settlement are subsequently affected with him in the call from somebody at the football. see that is teeming with life. starfish snails and ones could all be at risk from heavy muscles that could be looking in the rock dust. yeah, that's good to know. we have somebody nickel and mag on these, for example, can have a toxic effect on some organisms. but it has not yet been researched, how much is released, and whether it really has a negative effect on organisms. if that's exactly what we want to find out here, let's clean the weather as taking a 10 for the was

a fueled into cold and rain, or hampering the research as well. and this is the tricky part. the different mixtures have to be carefully distributed in the bed, so cost them that associates kind of thing live on the pentecostalism, dental kaufman. it's actually a byproduct of simon production. that is um, existing in total for splits and mens. we want to get just the right mixture canada, so it's all dissolved and there is no thick layer left at the bottom of the pen to cut some stickers fixed on. and um, for dispatch across the layer would also cover creatures on the see about taking costs in $1.00 in a few months. it will be possible to see exactly how well the process works by then results will also be available from experiments conducted in other locations, such as the coast of ground. canaria creatures live just below the water surface, the to the insurance on them of minerals added to the water is also being tested

enclosed contains. the potential of this message could be huge. of course the main one you need large quantity except for so also new ship so so on, for part of the loading capacity of existing ships could be used for distributing the rock down to about. but either way, we have to come up with a method to get the material into the ocean with them to come to the new method, such as here on the atlantic coast of laraca on the edge of the sahara. this plant is a way to extract in c o 2 from the atmosphere. lorayne l g, do the job in huge tanks. filed it just russell. you have lena came up with the idea l to naturally absorb c o. 2 from the volta and store. it's called

the fascinated gland. we learn very quickly how much light they mean, how many nutrients they need, what temperature they need. and this is the how much when they like, even just what makes these algae happy as it were. so they grow fast to organise moons and also have holes. the organisms are also very generous when they've been around for hundreds of millions of years and they're very patient to do it. so i may put up with a lot of our research and have them feed it for an open functions like tv tape and at the august the algae in these sit in this and the green house. i'll just 2 weeks old. now not for boston, not for the outdoor tanks yet. dr. russell ubida and his team has been for missing the project for 11. yes. the algae are indigenous to morocco. they grow especially quickly under the facilities conditions. the bio mass doubles in less than one day. in decent lives in this environment,

they can be very effective as to 30 times more effective than trees and extracting c o 2 from the air and i'm going the location on the roof composed is ideal. the algae like the local climate and lots of some the nutrients which was that comes from the sea and the electricity for the pumps and paddle wheels is from the cool wind. and so that's not how this thing takes place of just a few days. the algae are dried in machines or in the sun. this is how they end up looking. yeah, the gets here are dried algae. these into their now the hydrated, super, super dry and super salty. and we can now bury the valgy directly and they will last for several 1000 years. and um, the hudson done me is a $1000.00 buried in the deserts. so carbon dioxide can no longer escape.

as the aim is for the algae plan to operate as quickly and energy efficiency as possible. fuel vena and his team already one step ahead. in this experimental tons made of plexiglas senses constantly measure the conditions and adjusts the independence. the 4 optimal growth in this morning and the new green house we're trying out the technologies to automate or algae cultivation and so so ultimately is young. when they're going, algae can adapt very well to the environment, the arden, but we can also adapt the environment to the algae here in the greenhouse. you can imply posts off the owners on the auditing and post construction of a plum. 10 times launches. and this one is about to begin this option here in

southern morocco, 400000 tons of c o 2 could soon be removed annually. and that's just the stats in the line. and get this in morocco alone. there are 5000 square kilometers of land that's ideal t jobs. and that's just morocco, a model. phase 5 worldwide. there are about half a 1000000 square kilometers of a perfect land, flat sunny by the ocean. and what's the about $2000000000.00 tons of c o 2 per year could be suggested this way, about 5 and a half percent of current emissions. many companies are interested in the technology by buying c o 2 certificates. they could improve the calvin footprint of the the method wouldn't work in the gym in climate. but another one does, which also relies on biomass from some hey, most gab helped develop this kind of project and did run into class. and this

the role materials. oh garrick waste, in which plans have stored calvin actually visits the stuff that we use, the residual materials from would ship production. we'd be all similar which we obtain from the local board as to now. but we can use any other dr. plant residues here to produce bio charts. so that's our call from songs has been around for centuries. but gambles machine processors, the residues fall more efficiently and clean the and it's latest version. it runs entirely on its own energy, no home. so gases are released and the end the what chips are turned into bio char from the onset. so additionally we read discovered methods that already existed savings of technology from old civilizations, which was originally developed by indigenous people in brazil you didn't think so when we built the machine,

which can also be operated in central europe. yeah. and below which complies with the limits and also ensures that the heat generated can be used for all sorts of steep. i'm going to divide staple twice here in death, the energy is fed into the local heating great. the system is already working on this funding. new customers worldwide of the order of full so gamma and his team. the system being assembled here seemed to be installed in the usa of the payment since our buyers are comp posting plans, municipalities to cities, that process of green waste and the facilities was due on lot of fun moments of volume to say at least days. we also have industrial customers, the geology apply to our customer ranges, whitening due to climate change being such a massive issue. now on that part, on your home is by a chart is also produced in debt. we made most so dense money again, who works as plump manager at the op uh they take a sample of to buy it,

shaw that time, and then choose the quest is c o 2 from the atmosphere to have a great quality try base. you probably wouldn't want to eat it. it's mostly used as a di, as an additive and concrete. and even in skin scrubs or tradition, the social condition to an agriculture. and look under the microscope shows why they've gone to call it as income bio char, as a carrier income. oh wow. it works like a sponge. so for on this big binds and stores nutrients in water onto those alma and since our summers are getting hotter and hotter and it's raining less and less with extended periods of drought. but the bio chart is very helpful to you. i've got to have his advisor, muscles, and spun. also use this by a chart at home and he has got and he mixes it with sand and humus before planting his vegetables. and it seems it also helps on a small scale he says,

connotes got and will do in our kitchen garden, where we've added significantly more bio char. we don't have to water as much as we need. that's one effect which is very clearly achievable, seen by us. in this way, his gun is also making a contribution to the fight against climate change be. it's a very small one. winning the battle against climate change cannot only be achieved by technical solutions. on the positive side. so for lighting, avoiding a ton of c o 2, by not admitting it in the 1st place, costs is relatively little and a ton of recapturing a ton of c o. 2, that is already in the atmosphere costs much more than female damage. so you have to think through this, do you want to do nothing and pay $10.00 times as much? maybe 20 times as much 5. or would you rather save money and just do the obvious thing by not emitting c o 2 in the 1st place to on to stay as fine as well as for some high tech solutions are crucial to stop climate change bus. even the best

method cannot win the battle alone the, [000:00:00;00] the wood to us that's why we listen to their stories. reporter, every weekend, d w. what do you see? it really is possible to re 1st page researchers and

scientists all over the world for you know, race against time. they are peers and rivals with one daring goals to help smart nature. the more likes watching it. on youtube dw documentary, the, when a i read online, soon, scientists have already trained an ai to interpret your brain weight. also, experts argue that a poet, beauty fills with a potentially dangerous to the point of making you sick. we take a look at snapshot this morphia and how it comes about and why that's natasha,
