shouldn't use bellis courtney was in and out of hospitals. as his health became increasingly fragile. he leaves behind a new generation of more radical right wing populist politicians. bellis carney will receive a state funeral on wednesday at milan cathedral. that is your news update at this hour and all for me for now. so bell will be up in 45 minutes time with more just headlines and claire richardson in berlin from the whole team. thank you so much for joining us. the really profit tearing, instead of responsive the global business of as best as this is not legitimate because 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
8:16 pm
asbestos starts june 21st on dw john c o 2 vacuum cleaners. miracle dust in the fields. algae farms in 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 if it's 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 of i find the very unappealing of high tech innovations of breaking new ground. but can they really stop climate change? the
8:17 pm
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 summer's heat. weighs 2015 as on the lock to the lawn, which was exposed to the sun and turned into a field of stomach muscles. 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 it drowned. scraps was too much. the consequences of climate change. a palpable buzz here in the garden and more domestic. a alpha 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 getting up meet. there are so many constructive solutions that work well for you in the news. all will show us later
8:18 pm
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 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 carbon caps account is the 1st of its kind. okay. use of joined 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
8:19 pm
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 o 2. and we can capture and collect the heat is produced, it would lead from a geothermal power station. the old keeps on has collected full 1000 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's 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 move sean, so will be built soon. not just here, a nice scent. wherever there is volcanic rock, these accounts can be built as the c o 2 can be permanently stored in the row.
8:20 pm
that's what's happening under these english nearby the although it take to get 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 the deal, panama area. and what conflicts to us is to actually borrow that pipe and inject our c o. 2 chose water coming through the smaller my into the bigger one. and also going down into the word of a 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,
8:21 pm
as large quantities of c o 2. it's all the question of the right ratio between pressure, temperature and depth. that's what i'm holding here in my hands. this to course until the before and after of the carpets, not the one of them is the bus stop 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 seo tool when the water and the solves muscles in the wrong and forms a mineral called co sites. and this core that i'm holding here shows you the white sox 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
8:22 pm
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 the cost with us the all. and if there are other solutions that can make a contribution, which are perhaps less costly, the, the bypass by some can deflect direct. the air carbon capture is one way. there's huge potential that's put inside 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 a little bit can only be on a fission to all of our other efforts in reducing emissions. reducing that dependency on fossil fuels,
8:23 pm
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 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 as a $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 in the mountain work. it has to
8:24 pm
be done faster. and if we facilitate more research, of course, so relies on a small scale technical solution, putting up umbrellas to protect against the heat, to 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, and 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 time is 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. it's a volcano, did something that researches 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 form to them now. yeah
8:25 pm
. 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 common human, 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 hemmed up as researching how it could work well, they can nemaia into team on using data collected during volcanic eruptions. very different brought self or 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 and effect,
8:26 pm
but it has to the new maybe there'd be side effects we can't easily for 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 sulfur would be needed in the advocacy. there's people within that 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, 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 as 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. that's what i just know what 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 reaching research, which could very well tip the public mood and favor of such methods. of course,
8:27 pm
this would mean creating another artificial solution on top of artificial climate change, which is not such a nice idea either on the whole thing was not the concern, of course, didn't just dr. nima within one to see a political framework put in place to regulate the deployment of self of world wide . the idea was stocked 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 our salons, 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 without specially developed
8:28 pm
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 simple problems on his field. the machine is taking longer than expected to take figures for this
8:29 pm
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, 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 stop and fix them. but it also thing on the production of the material is also more expensive,
8:30 pm
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 soil. tobin 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 power train. as something it often say, it also works in that field. we have to assume that he only 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 these things, it's open in all directions, upwards, downwards to all sides. so it's hard to really trace where the product of our weathering ended up the whole are. they still stuck in the ground ice? maybe we can't recognize them at 1st and what we spot them again later. that's the
8:31 pm
challenge. let's try to talk to them on is sure to look and keep catching up to 5 percent of the c o. 2 emitted annually worldwide. the infrastructure already exists, and there is plenty of arable land. but there's even more ocean. the oceans already excelled around a quarter of the carbon dioxide emissions. and research has things to real. second 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 become an increase requested in the ocean and acidity levels need to be reduced. an experiment is currently being prepared at the g o mar, ocean research center into measuring pro site installed in these simple boxes,
8:32 pm
which are filled with soil and post. well, it's 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 of the hordes by filling the spend. so cousins with settlement from the baltic sea and pouring fjord watcher over it, we can simulate the sea bed of the baltic sea and andrea, the middle sporting, i know sea guidance and his 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 of dust will be added to the water as soon indifferent grain sizes and ratios. stuff comes to mind physics, taking the silica or carbon that we know that when they dissolve the marine chemistry, the chemistry of the seawater. sidney is changed in a way that means more c o 2 can be absorbed,
8:33 pm
acetate with. so i opened up matt and come a welcome side effect is that it also neutralizes harmful acidity and the voice in 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 the system and how the organisms in victoria and the settlement are subsequently effected with a meant to call some of the football see bid is teeming with life. stoffers 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 as taking a 10 for the was a fueled into cold and rain,
8:34 pm
a 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 live on depends on customers, dental kaufman. it's actually a 5 product of simon 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 dissolves and there is no thick layer left at the bottom of the going to cost them because based on the um, food dispenser costs we did a 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. but then results will also be available from experiments conducted in other locations such as the coast of ground. canaria preachers live just below the water surface, the to the insurance on them of minerals added to the water is also being tested
8:35 pm
enclosed contains. the potential of this message could be huge because the main one do you need large quantities to shift? so also new ships so, so and 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 messes, such as here on the atlantic coast. the blue rock has 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 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
8:36 pm
quickly how much light they mean, how many nutrients they need, what temperature they need. this is the how much when they like it 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 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 tank. see it? doctor russell ubida and his team has been submissive 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,
8:37 pm
they can be very effective as to 30 times more effective than trees and extracting c o 2 from the air going 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 algae are dried in 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 super salty. and we can now bury these algy directly and they will last for several 1000 years. and um, the husband and me is a 1000 calvin. buried in the test that soil carbon dioxide can no longer escape.
8:38 pm
the aim is low, 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 them independence. the 4 optimal growth in moines 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 a 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 positive construction of a plum. 10 times launches. and this one is about to begin. others options here in southern morocco,
8:39 pm
400000 tons of c o 2 could soon be removed annually. and that's just the stars in the whole court line. they 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 there 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 in climate. but another one does, which also relies on biomass from song hey, most gab helped develop this kind of project and did run into last. and this
8:40 pm
the role materials o gallic waste in which plans have stored colbin actually visits the stuff that we use, residual materials from would ship reduction. 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 all the cold from suns 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 what 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 doing things when we built the machine, which can also be operated in central europe and below which complies with the
8:41 pm
limits and also ensures that the heat generated can be used in the field all sort of steep. i'm going to divide staple twice. here in death, 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 governments of volume to say at least days we also have an nashville customers, the geology applied to our customer ranges, whitening due to climate change being such a massive issue. now when 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. so they take a sample of to buy it, shaw that time,
8:42 pm
and then choose the quest. as c o 2 from the atmosphere. 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. oh wow. it works like a sponge. so for on this big binds 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
8:43 pm
a small scale. he says the notes gotten with 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, 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. on the positive side to 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 female damage. so you have to think through this if you want to do nothing and pay $10.00 times as much, maybe 20 times as much 5 us 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 5th, find the mouse for some high tech solutions are crucial to stop climate change bus
8:44 pm
. even the best method kind of window baffled alone. the the in charlotte the currently more people than ever on the world wide in such a hassle. josh, are committed to actually find out about robina story info, migraines. imagine how many portion of lots of thrown out in the world climate change . the story. this is much less the way from just one week. how much
