the, the i'm tired of the 34 years. i was a middle i didn't know now i know the never ending story of asbestos starts june 21st on d. w. the giant's c o 2 vacuum cleaners. mary cooled us in the fields. algae farms and africa probably took efforts to stop the 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 with 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 high tech innovations of breaking new ground. but can they really stop the climate change? the must have and sun is during the rounds and has gotten 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 lock to the lawn, which was exposed to the sun and turned into a field of stomach and sells. it looked nothing like a lawn anymore,

and it looked like it was in southern spain, and it hadn't rained for 30 years. i'll think what it was alarming elf. 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. 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 electron liability 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 his involved in professionally intensive research and to climate change mitigation has been conducted for several years. now. in iceland, nature office, a 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 drawing connect is to filter carbon dioxide, harmful greenhouse gas from the atmosphere. the filter captures the c o 2 while releasing the cleaner air back into the atmosphere. and once the filters are full, you close us to compartments that the filter is in. and you apply sheets to uh, around a 100 degrees celsius, which released as a c o 2. so we can trap capture and collect the heat is produced, renew it bleed from it to you. it's m o power station. the oak of sand has connected $4000.00 tons per year. so saw the equivalent of the greenhouse gas emissions of $306.00. the people in germany, it's not a loss. i mean,

it's 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, smoothly built ceiling, not just hear a noise, cent. 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 english nearby the all the way of tech to good not son explains to us exactly how the company he works for the event, if the process is 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, to a panama area. and what conflicts to us is to actually borrow that pipe and injects our c o. 2 charged water coming through 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. and so the question of the right ratio between pressure, temperature and depth is what i'm holding here in my hands this to course until the before. and after off the top, it's not the one of them is the, uh, fast off the garage, 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 the c o 2 in the water in the sauce muscle in the wrong and forms a mineral called co sites. and this core that i'm holding here shows you the whites 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 learn 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. like 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 either by talk by some countries like 5 directly or

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 salt 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 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 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 fold below 0

current li, just to giga tons of carbon dioxide are extracted from the atmosphere to yeah. 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 if you see that some skate aside from the small sides, that is now as 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 want to go isn't what your goal is. we want to have a way to see the boy 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 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 power is sold 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 volcanoes did something that research has 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 formed man, which reflected unplug the sun life creation a kind of dry and shield like a parasol for the planet. for months, temperatures with half a degree cooler than usual. it's ok. 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 handed as researching how it could work. well, they can nehemiah and his team are using data collected during volcanic eruptions. median 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, since i knew maybe there'd be side effects, we can't easily for 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 self it would be needed in the advocacy. there's people within

that insight from 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 of house on 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. that's what i just know that should really only be used as a last resort in this one. 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. 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, or the idea was stocked 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 ice landing, 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 with that specially developed highly tech machines. the. what's the model is 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 the salt as a decomposition product. the conditions in the arable sewing are ideal. refunds and due to the 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 weathering 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 figures for this technology is actually designed for fertilizer for line. that's why too little is coming out as missing competition. so why don't 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 the us. i agree with 5. if i think you can see the effect of the neighbors fail 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 amount of a like mind, the finer we grind to the rock, the greater the surface area you can cover. there are pros and cons both ways. if you have very finely ground material with very little moisture and you get a lot of dust, when you distributed, stopping to compare the all spring on the production of the material is also more expensive. which is why the researches want 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. tobin almonds team at the university of handbook is investigating exactly how much c, o 2 is captured in the process. the results, the method works and not in, in the power train as something it often it also works in that field. we have to assume that you've got on it's just more difficult to prove it doesn't. and 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 of 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 and maybe we can't recognize them at 1st and what we spot them again later. that's the challenge as well. so i'll talk to him on is sure to book and could catch up to 5 percent of the c o. 2 emissions annually. worldwide. the infrastructure already

exists and there is plenty of arable land that there's 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 has come into being prepared at the g o more ocean research center into measuring pro, so installed. and these simple boxes, which are filled with soil and force, 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 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 the payments are now being done in the fence or customs without any risk to the environment. of dust will be added to the water as soon in different grain sizes and ratios. consume, i'd visit, they can do silicate or carbon inventory. when they dissolve the marine chemistry, the chemistry of the sea water, surely it's changed in a way that means more c o 2 can be absorbed. so it's i opened up mountain comes a welcome side effect is that it also neutralize is harmful acidity, and the volts in these processes can be precisely measured 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 exactly how the chemistry changes and how the organisms and the curia and the settlement are subsequently affected with a meant to call from somebody the football. c, 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 has taken 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 pen. so cut some because fish onto the um for the spectacle. some did a layer would also cover creatures on the c panel. i've taken calls from the one in a few months. it will be possible to see exactly how well the process works. but then results will also be available from experiments conducted in other locations, such as the coast of crime. 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, if this makes it could be huge because the main one you need large quantities of your 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 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 over the extracting c o 2 from the atmosphere. lorayne l g, do the job in huge tanks. while they're just russell, you're lena 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 fat 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 in these sit in this, 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. the 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 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 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 algio, dried and machines or in the sun. this is how they end up looking. yeah, the units here are dried ality these into their now the hydrated, super, super dry and some for solving on. we can now buried these algae directly and they will last for several 1000 years. and um, the hudson done me is a 1000 gallons of is buried in the desolate soil. carbon dioxide can no longer escape. the aim is fully 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 plexiglass fences constantly measure the conditions and adjusts them independent. see for optimal growth 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 imply posts of the owners on the auditing and passing construction of a plum 10 times launches. and this one is about to begin uh, this options here in southern morocco, 400000 tons of c o 2 could soon be removed annually. and that's just the stars in the line. and get this in morocco alone. there are 5000 square kilometers of land that's ideal yards 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 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 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 cab i helped develop this kind of project and did ryan and politeness develop materials oh garrick waste and which plans have stored colbin actually visits. the stuff that we use, residual materials from would ship production. we'd be all assume look which we

obtain from the local forest and all that. but we could use any other drive plant residues here to produce bio charts. so that's always 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 harmful gases are released in the end, the wood chips are turned into bio char from the onset. so additionally we read discovered methods that already existed savings 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 in the field. all sorts of steep i'm going to divide stapled spice, here in death. the energy is fed into the local heating great. the system is

already working and just finding new customers worldwide. the order for a full, full 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 are still on the fund moments of value to say at least days. we also have an spill customers. the, the, all the provides are 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 death. we made most so dense mon again, who works as plump, manage it up. yeah. but so they take a sample of to buy it, shaw that time, and then choose the quest. as c o 2 from the atmosphere. you have a great quality strategies. 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 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 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 in it. it also helps on a small scale. he says, can not scott and will the 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 as anybody 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. on the positive flights of from items 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 a 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 and a tool on the states find the smallest for some high tech solutions are crucial to stop climate change. bus even the best method, cannot win the battle alone. the

of the is germany becoming irrelevant. doing business in the country has become more and more unattractive. due to cumbersome, huron, and high taxes, inflated energy costs and labor shortages are only making things worse. germany and beacon nomic powerhouse no more made in germany on dw, the

watching the news coming to live from berlin, germany on bills. it's 1st of our national security strategy. it outlines the government's board and defense policy, and also how it sees itself in the world. we look at what it could mean for germany's allies also coming off of show russia once again targets.
