the culture information, this is the, the news w. from mines we are all set and we're watching closely. we all seem to bring you the story behind the news. we're all about unbiased information. all 3 months. done the giant c o 2 vacuum cleaners. very cool dust in the fields. algae farms in africa, high tech 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 to 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? their condition, we can take one problem or humans have created to add another on top of i find the very unappealing of dots, high tech innovations of breaking new ground. but can they really stop climate change? the most sense one is doing the rounds and has gotten in west and germany's ryan has the region. most of his plans have recovered from last. some is huge way. 2015 as on the lock to the lawn, which was exposed to the sun and turned into a field of stomach myself. it looked nothing like a lawn anymore and it looked like it was in southern spain, and it hadn't rain for 30 years after it was alarming. all good. at one point we

just stopped watering it if the ground scratched was too much. the consequences of climate change a palpable bose here in the garden and more domestically elsewhere in the world must and spend the least that's 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 intensive research and to 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 old colvin 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 sheets to around a 100 degrees celsius, which released as a c or 2 that we can capture and collect the heat is produced renew, i believe, from a geothermal power station. the old keeps on has collected $4000.00 tons per year. so saw the equivalent of the greenhouse gas emissions of $360.00 people in germany . it's not a last, 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 to 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 row. that's what's happening under these english nearby the although it take to good not sun explains to us exactly how the company he works for the event. if 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. 2 kilometers deep into video, panama area. and what conflicts to us is to actually borrow that pipe and injects our c o. 2 chose water coming to the smaller my into the bigger 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 pressure, temperature and depth. what i'm holding here in my hands is to course a chill the before the of the topics, not the one of them is the best sound signal, but 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 this seal, so when the water, the 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 with us. and if there are other solutions that can make a contribution, which are perhaps less costly the, the by product 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 salt trucks and 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 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 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 atmosphere. this is known as negative emissions because needs to fall 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 as a $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 isn't. which goal is we want to have a way to 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 for them by who they 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 it goes to what is the idea of a giant power is sold to cool the whole time is a crazy one are actually knows. it's been around for some time. in 1991, the peanut to the volcano erupted in the philippines. hundreds of people that killed the damage was enormous. hit the volcano did something that research has all over the world have been studying ever since. the volcano ejected salsa gas into the stratosphere, where it's reacted with oxygen to form tiny particles. this formed familia, which reflected, unplug the sun, life creation, and kind of drying shields. look at power. so for the planet. for months, temperatures will half a degree cooler than usual. it's ok, nose can do is quite calm. human special ed across could bring the sofa up to the

stratosphere. technically it is possible to create an artificial shield against the sun, the box splunk institute for me to reality and humbug as researching how it could work well, they can nemaia and hit team on using data collected during volcanic eruptions. when we did, if we brought software into the atmosphere, it would be globally distributed in all directions by air currents that would affect everybody. this is exactly what makes it difficult to assess the impact and consequences in uh we have to see what the impact of a saw for emission up there would be what kind of crime, in effect what it has done the maybe there be side effects. we can easily for single categories upsets and couldn't, would you to apply 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 in the advocacy. just people have opened and 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 the house on the understand no one has yet dead to attempt such a technical intervention in the course of nature that suitable at cross could be available in just a few. yes. i for the i just knew it 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 reaches music, which could very well tip the public mood and favour of such methods. of course, this would be creating another artificial solution on top of artificial climate change, which is not such a nice idea either on the whole thing was 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. the 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 in iceland, excellent, 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 with that specially developed high tech machines on this dip 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 the 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 of old problems on his field. the machine is taking longer than expected to take fingers. this technology is actually designed for fertilizer for line. that's why too little is coming out as missing competition survey. but let me 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 the us go with 5. if i think you can see the effect of the neighbors failed to with a debriefing 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 you find that this might have a like mine, but the finer we grind to 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 distributed, stopping to compare to all spring on the production of the material is also more expensive. which is why the research has one to use existing pouted wrong. 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 the

tub and almonds team at the university of handbook is investigating exactly how much c, o 2 is captured in the process. the result, the method works and not in, in the far tree. as something it often say, it also works in the field. we have to assume that he only got on 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 because it's open in all directions on boards 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 and maybe we can't recognize them at 1st and what we spot them again later. that's the challenge. let's try to talk to them on is sure to book and keep catching up to 5 percent of the c o 2 emissions annually. worldwide. the infrastructure already exists and there was plenty of arable land.

about these even more ocean. the ocean was already absolute around a quarter of the carbon dioxide emissions and researches things. the real 2nd 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 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 post was only a guy not and who research team called these boxes been cousins, doors own. we have managed to bring the c bed to the floor and how to go who works there by filling these pencil 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 sporting, i know sea guidance and hid team have retrieved, settlement from the sea 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 soon in different grain sizes and ratios. come from, i'm taking the silica or carbon, let me know. when they dissolve the marine chemistry, the chemistry of the sea 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 neutralizes harmful affinity in the most in of 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 effected with him in the call from somebody at the football. c bed 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. i mean 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, holes clean the weather is taking a 10 for the was a fueled into cold and rain on 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 5 product of some and production that is um existing in total cost. but it's a mens we want to get just the right mixture, canada, so it all dissolved and there was no thick layer left at the bottom of the going to cost them because based on from the um for the special costs we did. a layer would also cover creatures on the sea, but i'm thinking so close to the one 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 preaches 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 because the main one do you need large quantity shift so also new ships so, so and for part of the loading capacity of existing ships could be used for

distributing the rock das here. how 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 message 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. biologist, raphael, you have lena came up with the idea? l chain naturally absorb c o. 2 from the volta and store is called the 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 it just what makes these algae happy as it were? so they grow fast, do organisms 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 functions like tv tape and at the the algae in these sit in this, in the green house. i'll just 2 weeks old mamma for bust enough for the outdoor tanks yet. dr. so you, vena and his team has been semester and 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. and of course the location on the american coast is ideal. the allergy in like the local climate and lots of some the new to enrich 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 units here are, are dried ality these into their now the hydrated, super, super dry and some personal and fee on. we can now bury these algy directly and they will last for several 1000 years. and um, the husband and me is a $1000.00 varied in the test that soil of carbon dioxide can no longer escape. as the aim is slowly ality planned 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 them independent. see for 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 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 stars in the line to get this in morocco alone, there are 5000 square kilometers of land. that's ideal t jobs and, and that's just morocco, a model phase 5 world wide. 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 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 calvin 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 kind of project and did run into last in this the role materials. oh garrick waste, in which plans have stored calvin actually visits the stuff that we use, 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. plan residues here to

produce bio charts. so that's our cold from sons has been around for centuries. but gambles machine processors, the residues fall more efficiently and clean the and its latest version. it runs entirely on its own energy. no home. so gases are released in the end. the wood chips are turned into bio char from the onset, se additional and we read discovered methods that already existed. simmons, the technology from old civilizations, which was originally developed by indigenous people in brazil, you didn'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 at all sort of steep, i'm going to divide staple twice. here in decades the energy is fed into the local heating grid. the system is already working on this finding new customers worldwide

. the order for a full, full gather and his team, the system being assembled here seemed to be installed in the usa of the hop name of since our buyers are comp posting plan, municipalities to cities that process green waste. and the facility has to unlock upon moments of volume to say at least days. we also haven't spill customers, the geology applied to our customer ranges, widening due to climate change being such a massive issue. now the applied on your home is by a chart is also produced in debt we made most so then someone again who works as plot manager at the alba. they take a sample of to buy it, shaw that time, and then choose the quest. as c o 2 from the atlas van, great quality strives you probably wouldn't want to eat it's. 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 put on to call it as income bio char, as a carrier income hosting schwab. it works like a sponge. so for on this page, vines and stores nutrients and water onto those on the image. 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 5585 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 it also helps on a small scale. he says, can not scott 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, etc. but in this way, his gun is also making

a contribution to the fight against climate change will be it's a very small one. winning the bass will against climate change cannot only be achieved by technical solutions. products insights if i might and avoiding a ton of c o 2 by not emitting 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 female the and 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, the to on the 5th fine as well as for some high tech solutions are crucial to stop climate change bus even the best method, kind of window baffle 11 the
