on the news last, check it out the 77 percent in 60 minutes. on d w. we are all set and we're what seeing closely we all seem to bring use a story behind the news. we're all about unbiased information for 3 months. done the giant c o 2 vacuum cleaners. mary cooled us in the fields. algae, farms and africa probably took 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? the condition we can take one problem or humans have created to add another on top . i find the very unappealing of dots, high tech innovations of breaking new ground. but can they really stop the climate change? the son is doing the rounds and his garden in west and germany's ryan has to reach him . most of his plans have recovered from last thomas heath way, 2015 as on the large lawn which was exposed to the sun and turned into a field of stomach muscles. it looked nothing like a lawn anymore. i think it looked like it was in southern spain. it,

it hadn't rained for 30 years after it was alarming. all good. at one point we just stopped watering at the ground scraps was too much the consequences of climate change. a palpable buzz here in the garden and more dramatically elsewhere in the world. massa and spun belief that something has to change on a small, as well as a 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 getting 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 his involved in professionally intensive research and to climate change mitigation has been conducted for several years now. in iceland, nature offers the 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 old colvin catch up sound is the 1st of its kind. okay, use a dr. connect to is to filter carbon dioxide a harmful greenhouse gas from the atmosphere. 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. and we can tap the capture and collect the heat is produced, renew, believe from it to you. it's m o power station. the old keeps on, has connected $4000.00 tons per year. so saw the equivalent of the greenhouse gas emissions of $360.00 people in germany. it's not a loss, 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 move sean slowly build ceiling, not just hear a noise, cent. wherever there is volcanic rock, these accounts 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 getting that sun 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 best we're looking at, there's

a pipe from the jail, from a power plants injecting the 2 of them on the water back into the ground, to kill them into the, into the panama area. and what conflicts to us is to actually borrow that pipe and injects our c o. 2 charged water coming to the smaller might enter the big one. and also going down into the weight of 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. it's all the question of the right ratio between precious temperature and what i'm holding here in my hands is to course a chill the before and after a conference, not of the one of them is the 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 cecile, so when the water, this solves muscle,

in the rock and forms a mineral cold 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 at the end. if there are other solutions that can make a contribution, which are perhaps less costly the, the bypass by some countries like 5 direct their carbon capture is one way. there's

huge potential that's put inside of this whole at least in places where there is enough. but 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, all of that can only be on a fission to all of our other efforts in 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 degree celsius of laid out in the 2015 power as climate is agreement, but to ensure this existing greenhouse gases also have to be removed from the atmosphere. this is known as negative emissions because needs to full below 0

current li just to get 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 from the small size that is now and mountain 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 the go as in which goal is we want to how is i see the volume at home and is got in my sense, mind 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 play

boxes at 30 degrees in the shade with direct sunlight the garden, the face of south north it's not very sensible to be there without shade one of us out on the front of the stall, as he also had is the idea of a dry and powered soul to cool the whole scientists a crazy one. actually knows. it's been around for some time. in 1991, the peanut to the volcano erupted in the philippines. hundreds of people were killed and the damage was enormous. hit the volcano did something that researches 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 form to them now? yeah. which reflected, unplug the sun, life creation that kind of dry and shield like a power solve for the time it. for months, temperatures will have a degree cooler than usual. it's ok, nose can do is quite calm. humans,

special ed across could bring the salsa up to the stratosphere. technically, it is possible to create an artificial shield against the sun limits splunk institute for me to reality and humbug as we searching how it could look. whether they can be maya and her team are using data collected during volcanic eruptions. when we do different brought so 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 the so we have to see what the impact of a saw for our mission up there would be what kind of crime and effect. but it has to end on the maybe there'd be side effects we can't easily for a single categories upsets and couldn't would you the by to it could change rainy and dry seasons regionally with consequences for farm is it's also not clear how much self it would be needed and it should be if it had only offended insights,

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 stop 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, but suitable across 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 research, 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 must 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, or the idea was sparked by volcanic eruption. volcanoes also happened to provide the rule materials for office solutions, which could permanent a. we may have c o 2 from the atmosphere. volcanic rock can be used as a greenhouse gas, think not just an orthodontic, 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 developed highly tech machines. still showing what we're doing here is accelerating a natural process and see the weathering 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 to meet 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, but is requires more research on a gale cost is already struggling with $1.00 of the most amount, simple problems on his field. the machine is taking longer than expected. take fingers for this technology is actually designed for fertilizer for line. that's why too little is coming out as missing competition. so we just improvise and double back out there is less of of how to draw,

which is very fine. and drawing creates a lot of the us go with 5. if i think you can see the effect of the neighbors failed to with the briefing with the scientists, the method and the formulas still need some look every field and every kind of soil is different. grain size makes a difference to the final does not of a like mind. the finer we grinds, the rock, the greater the surface area you can cover. there are pros and cons both ways. and if you have very finely ground material with very little moisture and you get a lot of dust when you're distributed, stop and pick them. but also putting on the production of the material is also more expensive, which is why the research is one to use existing powdered roll. if possible. it could be found by the ton simply 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 often say, it also works in that field. we have to assume that he only got on, but it's just more difficult to prove it doesn't. then of course of field is not in close, like a bucket or a tube or a huge rain barrel used for an experiment kind of easy because it's open in all directions and love words downwards to all sides. so it's hard to really trace where the products of our weathering ended up the whole are. they still stuck in the ground and maybe we can't recognize them at 1st and what we spot them again later. that's the challenge also to talk to them on is sure to look and could catch 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 oceans already excelled around a quarter of the carbon dioxide emissions, and researches, things to real thinking might be much higher. 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 be permanently sequestered in the ocean and acidity levels, need to be reduced. an experiment is currently being prepared at the g o mar, ocean research center in to measuring pro, so installed. and these simple boxes, which are filled with soil and ppos, was only a guy not and who research team called these boxes been so cousins, doors own. we have managed to bring the c bed to the tour to go horse, and by filling these bend through customs with settlement from the baltic sea and

pouring fjord watcher over it, we can simulate the sea bed of the baltic sea and via the middle school. 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 bins or customs without any risk to the environment. to rock dust will be added to the water soon in different grain sizes. and ratios come some i'm physically taking the silica or carbon, let me know 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. acetate with sly, open on that and come a welcome side effect is that it also neutralize is harmful acidity, and the most in these processes can be precisely measured fan for seen as we have different codes that we insert into the settlement itself. and some that we measure

at the surface so we can determine excess, clear how the chemistry changes the system and how the organisms and the curia in the settlement are subsequently affected with a meant to call from somebody the football. see bed is teeming with life. stuff which snails and ones could all be at risk from heavy muscles that could be looking in the rock dust. yeah, they have a good, good know they have somewhat nickel and manganese, 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, holes clean, the weather is taking a 10 for the was a fueled into cold and rain on humphrey the research as well. this is the tricky part. the different mixtures have to be carefully distributed in the bin, so call some associates categories,

financing live on depend to customers, invented kaufman. it's actually a byproduct of some and production that is um in total cost for that segment. we want to get just the right mixture canada, so it all dissolves and there is no thick layer left at the bottom of the going to cut some because fish on it. and i'm going to spend because we did a layer, would also cover creatures on the see about taking costs and $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 cost of grand canaria. preachers live just below the water surface, the to the insurance on them of minerals added to the water is also being tested in close containers. the potential of this makes, it could be huge because the main one, you need large quantities of shift. so also new ships to so and for part of the

loading capacity of existing ships could be used for distributing the rock das here . but either way, we'd have to come up with a method to get the material into the ocean with them to come to the new messes, such as here on the atlantic coast of morocco, on the edge of the sahara. this plant is already extracting c o 2 from the atmosphere. lorayne l g, do the job in huge tanks. file to just drop the came up with the idea. l chain naturally absorb c o 2 from the volta and store it as called fascinated gland. we learn very quickly how much light they mean, how many nutrients they need, what temperature they need. this is how much when they like, even just what makes these algae happy as it were. so they grow fast to organise moves 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 they've put up with a lot of our research and have them feed it for an open fashions like tv tape and at the the algae and the student is in the green house. i'll just 2 weeks old mamma for a bust enough for the outdoor tanks yet. doctor 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 . they buy a mass doubles in less than one day in decent lives in this environment they can be very effective as is 30 times more effective than trees and extracting c o 2 from the air looks going. the location on the american coast is ideal. the allergy in like the local climate and lots of some the nutrients which was that

comes from the sea and the electricity for the comes and paddle wheels is from the cool wind. and so that's not how this thing takes place of just a few days. the algio, dried and machines or in the sun. this is how they end up looking. yeah, the gets here are dried elegy these into their now the hydrated, super, super dry and super salty. and we can now bury these algae directly and they will last for several 1000 years. and um, the hudson done me is a $1000.00 buried in the test that soil of carbon dioxide can no longer escape for the amos for the algae plan to operate as quickly and energy efficiency as possible . you'll vena and his team already one step ahead

in this experimental tons made of plexiglass fences constantly measure the conditions and adjusts them independent. see for optimal growth here in moines and the new green house, we're trying out the technologies to automate or algae cultivation and so so ultimately these young on the born 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 type house of the owners on the items and passing construction of a plant 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, and that's just morocco. mobile phase 5 world wide. there are about half

a 1000000 square kilometers of a perfect land, flat sunny by the ocean, and go to what's about 2000000000 tons of c o. 2 per year could be sequestered 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 carbon footprint of the the method wouldn't work in the gym and climate. but another one does, which also relies on biomass from some hey, most gab helped develop this pilot project and did run into class. and this the role materials o gallic waste in which plans have stored colbin actually visits. the stuff that we use, the residual materials from would ship production would be all similar which we obtain from the local board as to now. but we can use any other dr. plan residues

here to produce bio charts. so that's our cold from suns 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 in the end the what chips are turned into bio char from the onset. so additionally we read discovered methods that already existed. simmons, the technology from old civilizations, which was originally developed by indigenous people in brazil. you don't take to and we built the machine which can also be operated in central europe and below which complies with the limits and also ensures that the heat generated can be used in the fuel sort of steep. i'm going to divide staple twice. here in decades, the energy is fed into the local. he's in great. the system is already working on

this funding, new customers worldwide, to the orders. let's also so gather and his team. the system being assembled here seems to be installed in the usa of the payment since our buyers are comp posting plan, municipalities to cities that process green waste and the facilities was due on the fun moments of value to say at least days. we also have industrial customers, the be applied to our customer ranges, whitening due to climate change being such a massive issue. now in that fight on your home is by a chart is also produced in debt. we made most so dense money again, who works as plump, manage it up. yeah. but they take a sample of to buy a child at time and, and choose the quest is c o 2 from the atmosphere. the great qualities try based on you probably wouldn't want to eat it. it's mostly used as a di,

as an additive in concrete and even in skin scrubs or tradition, the social condition to an agriculture. and look under the microscope shows why they pronounce a cooler. this include bio char as a carrier and com. oh, the bottom it works like a sponge and so for on the split binds and stores nutrients and water onto those all my m a. 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, so i thought it would fuzz myself. and this one also uses by a chart at home. and he has got in he mixes it with sand and humus before planting his vegetables in it. it also helps on a small scale he says, can look got and we'll do in our kitchen garden where we've added significantly more bio char. we don't have to water as much as we. that's one effect which is very clearly achievable. think of us in this way, his gun is also making

a contribution to the fight against climate change be, is a very small one. winning the battle against climate change cannot only be achieved by technical solutions and the products, insights of amazing avoiding a ton of c. o 2, by not admitting it in the 1st place, costs relatively little and a ton of recapturing a ton of c o. 2, that is already in the atmosphere costs much more than a female damage. so you have to think through this, what 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. the tool on the states find the smells for some high tech solutions are crucial to stop climate change bus even the best method cannot win the battle alone. the

of the choosing the joy of the ride over the annoyance of the traffic gunners revolution. nissan rex. to verify thing is visible, but now that unions was checking out the 77 percent in 30 minutes on dw sustainable farming for green washing capital. farmers in australia have discovered a lucrative following cost on emissions trading. they return grazing language to it's an actual eco system and receive credit for it. but it's,

it's really environment friendly. critics down to it was the few minutes on d, w, or sports, all of our scoring we say they were about never giving up sports life every weekend on dw the this is dw news, and these are all top stories. former us president donald trump has pleaded not guilty to 37 criminal charges brought against him in a code in miami after being released from met with supporters telling them that the government's presides have control.
