every place of senior junior in a country like turkey taking on the powers that be they risk everything, john dunbar, meets activists, journalists, and politicians living in exile. they will em tortured the live for their mission. what drives them? could be nice to know what is happening there are ceilings, guardians of truth watch now on youtube, d. w documentary in the northern hemisphere. every one is longing for spring, but hasn't it arrived already for years, many plans have flowered earlier and earlier. this has consequences for insects that need the flowers and 4 birds that feed on these insects is our ecosystem going off the tracks. hello and welcome to

to morrow to day this science program on d. w. ah, the weather around the world no longer follows the calendar. the consequences of global warming are obvious. but what can be done to stop climate change? many are counting on green hydrogen. yet even germany cannot produce enough itself . that is why it wants to import it and is counting on international partnerships. for example, with angola, low dom and on the golan hair, a hydro electric power plant generates green electricity. the cohen's a river provides the water. it's the largest river in angola. whether it's the rainy or dry season, according to the operators that always carries enough water to produce enough electricity. the capacity is enormous, but not in half is used. little girl,

that you my capacity that these loca, has a capacity of 2070 megawatt lentil d, on average, was we produced between 70800 megawatts a day at st bush. so you can see that at the moment, bless, we are not using our full potential image at the airport. this yellow me lot out of 6 main turbines, a maximum of 3, a currently running meaning unused hydropower. germany should benefit from this surplus. electricity could be exported to germany in the form of green hydrogen. the 1st german angle and hydrogen symposium took place in angola in may. 2022. talk a little bit about or girls comes from produce symposium is starting point for the symposiums is the understanding that a successful energy transition would not be possible without green hydrogen on the top of the store. in the fact that germany will be dependent on in ports of green hydrogen in the long term line built of important fun gluten versus shutoff. just

over a month later, a memorandum of understanding was signed and berlin. the plan, together with san angle and girl estate oil producer, the 2 german companies, golf and con, yanked her want to bring green hydrogen to germany. rehab mine, we have identified a joint project here we are talking about an electrolysis capacity of $400.00 megawatts, right in the port area of borrow. dana repeat, borrowed under angela, is one of africa's largest oil producers. but stay turns on. angle is increasingly investing in green technologies. the project with germany office, san angle, an opportunity to further strengthen the company's green division, which but arm was north in now that we hope will then at the end of this process, there will be on the winners will confirm in the following sense of following source then probably that diversification and sustainability of san angles

portfolio in that meant if it, the, for an effective position was an angle in the energy transition. but almost found the promotion of technological and innovative research were foul and a transfer of knowledge transferred or greasy men. from germany's point of view and goal is advantages as a partner and not only its great potential in terms of solar, wind, and hydro power, but also the fact that the country knows its way around the energy market. in addition, in this specific case, part of the infrastructure already exists. the low cut dam is located in the north west of the country. from hair, there's already an existing over landline that transports electricity to the coast to the town of beret or dander. san angle is building a port hair originally for the transport of liquid derivatives, but now an area for green energy projects is being added. the location has some

advantages for german companies. gaffes managing director says that sooners, the nice thing is at the port. we already have drinking water supply there. so because we also need water for electrolysis, which is a big river nearby, that's also huge advantage. so we don't have to do any desalination of sea water like in other areas. we have the complete export infrastructure already there, but among other things and electrolysis plant has to be built here in the port. hydrogen will then be produced using electricity from low occur and water from the nearby river. the electricity is used to spit the water molecules h 20 into hydrogen, h 2 and oxygen o 2. in another step, nitrogen and 2 is added creating ammonia and h. 3. ammonia becomes liquid under high pressure. the conversion to ammonia makes sense because it's easier to transport than

hydrogen. the liquid ammonia will then be loaded on to ships here and delivered to germany. does hosted with that means there will then be a large ship landing on the atlantic ocean coast a bit north of luanda, one for this would then be loaded with probably $78085.00 and tons of ammonia from us 4 times a year. so we expect a total production of $280000.00 tons of ammonia annually. it wasn't on normal nick and germany. the ammonia can then be converted back into hydrogen and used for energy production. angola could thus be the 1st country in the world to supply germany with green hydrogen. if all goes well, green energy from lucca could begin its journey to germany in early 2025. according to current plans, that would be the equivalent of 1450000 megawatt hours per year. that would be enough to supply around $450000.00 households with electricity career

might as most of the snow seem to fall where it's not needed. and not in places that needed for winter sports, like the alps where this february was 3 degrees warmer than usual. globally, climate change is playing havoc on the weather and we have to get used to more extreme weather events like droughts and major heat waves. not to mention storms and heavy rain, we humans have to adapt. and so to all other species in springtime has arrived in germany, meaning more time to baskin that lovely sunshine. nature emerges from hibernation and we can delight and the resulting rich pageant of color. and isn't it great when you are mornings, get off to such a warm and sunny start the phase and get him? i'm not so sure can. it's not just us who spring starts early for plants and

animals to write in in fooling, which could mean them getting out of sync with each other. biologist, christina, women and her team are looking at the impact of climate change on nature. when this up when species miss each other, as well as the risk of some actually dying out all stem. the field of phonology involved the study of recurrent natural events in relation to seasonal changes. the fin a logical calendar divides the year into not 4 but 10 seasons. each of them beginning with a biological state of a specific plant. the calendar starts with hazelnut blossoms and ends with a large tree, shedding their needles. but there's been a shift and athena logical seasons, as is evident from a comparison of data from to day and a period between 19611991 instead of on march. 3rd spring now dawns more than 2 weeks earlier on february 14,

which at the same time makes winter shorter. and that shift is a consequence of climate change. apple trees starting to blossom. another typical indicator of spring has moved forward in germany by 10 days over the last half century. and there have been similar changes in the animal world, 2 short distance, migratory birds. and those at hibernate, such as tips, now started reproducing about 2 weeks earlier. and at this point, potential breeding side rivals, long distance migrants like pied fly catches and red starts have yet to return from africa. the timing of the migration is genetically programmed, and based on the length of days, there are winners and losers. the earlier arrival of spring is called season creep and has an effect on reproductive cycle feeding relationships and competitive systems. christine roman is also a senior member of finance. a project comparing plans and botanical gardens in different parts of the world, stands a transcript on decline of imagine you have

a small plant under larger plant plans because you got that competing for food and water of course. but above all, the sunlight column list one been unequal, suffolk, sick of normally the small appeal benefits from its life cycle being quick, hind figure flung in for, but that's advantage is gone. if the larger plant sprouts earlier was 5 big thing, plant we haven't. labels took less abstract. less exposure to light is bad news for plans. ecosystems are sensitive by nature and interactions between plants and animals are finally tuned. in time to phase the life cycles are like interlocking gears. when one partner engaging too late or too soon control spanner in the works . the advent of spring seas flowering plants, pollinated by insects and then blossoming. insects become more active as temperatures rise. plants on the other hand, take the cues to sprout from other signals, such as soil humidity and longer days. so sometimes,

insects might not be out and about why the plants are in blossom. and as they miss each other, the former are denied food. and the latter, there pollinators, the phenomenon has yet to be thoroughly researched. but what is already clear is that extreme weather conditions in the wake of climate change increase the likelihood of a plant pollinate or mismatch among the species at acute risk or specialist like the scarce large blue butterfly. in order to produce young, it's dependent on its sol hose plan, the great burnett blossoming at the same time, it lays its eggs. the butterfly is one of around a 1000000 species under threat from climate change. one and 3 species of plant and animal. and those rely on their own nature are especially vulnerable yard, as common as a general rule, the more specialized the species as the bigger problems it will have with changing environmental conditions school and the 1st to die out are the specialists species

that are highly adapted to particular conditions, but they will be followed by the more flexible generalists and the disappearance of species means that the ecosystem start to break down. they come under increasing pressure and face a growing struggle to recover from extreme weather events. and that in turn, she was the extinction of further species. their demise also means the loss of functions that are crucial for humans. many of the crops would grow, eat, or fee de livestock need animals to help generate seeds and fruits venue. in fact, insects are not present and sufficient numbers on it will obviously have an impact on plants, reproductive success, and on fruit vacation, which will be visible in harvest yields, under our name at honda. while earlier springs at 1st sight seemed like something to welcome, they mean excessive stress for nature and for a lot of ecosystems of a major threat. so the honest is on us to put the brakes on climate change and

preserve them precious diversity of flora and fauna. oh, it's an old tradition in many countries. when spring arrives, the house is thoroughly marked out in what is usually simply called spring cleaning . but that household dust is not only a nuisance, it can also be bad for your health. a whole range of environmental toxins can be hidden in it. a good reason to take a closer look at those tiny particles. ah, no self respecting home would be complete without them, and they typically hang out in neglected corners nooks and crannies. dust bunnies. oh, how stuff looks awful and is annoyingly persistent. although

it appears gray, it's actually a rather colorful mixture. about 80 percent of house dust is made up of tiny textile fibers from clothing. so 1st and carpets then there are flakes of dead skin shed by both ourselves and our pets and her again of human and animal origin. miniscule parts of pants and fragments of insects and fine grains of sand carried in from the streets, no shoes. and that's just what we can actually see. dust also contains invisible particulate matter, some of which is created when we toast or fry food. or even if we blow out a candle after a romantic dinner for 2, but the main dust sling as ourselves, even when we sit still, we release around

a $100000.00 dust particles per minute. the slightest movement can release about $1000000.00 particles and more significant movements can release as much as $10000000.00 particles per minute. the dust we find in our bedrooms is a bit different. it's mainly made up of shad skin which turns our pillows and mattresses into a special bio type for a tiny parasite. the dust might doth mites feed exclusively on human skin flakes. a teaspoonful of bedroom dust contains about a 1000 mites and nearly a quarter of a 1000000 of that vehicle droppings. we breathe in these droppings while we sleep, and it's these that trigger house dust allergies. oh,

every liter of air in a typical german home contains up to 50000000 floating dust particles. when the air is warm, they rise. when it's cool they fall down again. which is why so much dust gathers on the top of furniture. but it's not just dust particles that rise in the wall. ma'am, there are also substance as a method from our flaws, furniture and wall paper. these vapor particles invisible to the human, i get caught up in larger dust particles. germany's federal environment agency has looked into what exactly accumulates in the da and it's not good news, as environmental toxicologist marie kirk. i'll asa gary explains madame's doctrines if you live many pollutants,

get caught in the dust for keeping them in your indoor space and an armored mob lift how these might be passed. the sizes, for example, many of which are toxic for our reproductive organs from schofield and the skin. and then there are also fear sides or flame retardant. or other substances such as d, d. t's or people, or bees, which are hardly degradable. we up our barzon, broken human, these can damage our immune systems and effect various organs as jim some of the substance as a suspected of cause and cancer. so disturbing our fat metabolism or promoting obesity of fixes is a very wide spectrum, does forget the spectrum's applied oh, so it's time to rethink our perhaps overly casual attitude to dust. what are the scientists suggest? silva mom is going to cleaning is very important and that means mopping floors and also wet vacuuming. this is the mature dish, that's the best and most reliable way to remove dust nitrogen and airing is important to this ventilation improves indoor air quality and gets rid of some of

the police target tighter shots of him. i've asked harden this method. on the other hand is rather less effective, at least when it comes to pollutants. philadelphia into stops, organ and fancy, didn't stop as many people think that back seeming remove stuffs from the home. props already, but in fact, most machines just disperse it more. so does he, so it's important to dust using a damp cloth and walk down flaws, stopped rushing of forged fissions against which to your mouth. numb microfiber cloths can be effective hair, in addition to attracting dust particles, almost magically. that tiny fibers also hold on to them particularly well. plus, you don't need a cleaning agent. so it's good bye to those fluffy little dust bunnies lighted dust particles. don't make it all the way to the lungs. ultra fine particles on the other hand can. more than 100000 of these tiny particles can float

in one cubic centimeter of air on busy roads. it's one reason why diesel engines have gotten a bad reputation. what many people don't know is that heating with wood is even worse when it comes to fine particulate matter. heating with wood is becoming increasingly, carmen. wood ovens are inexpensive, but they have an unwanted side effect as people cozy up to the oven. inside of their rooms, the smoke can be harmful to health outside. according to you, climate packed ambassador on your barons. look 1st, what song is, the appellation is the largest environmental risk factor for premature death towards failure. you know, what are your opinions die an average of 2 years earlier because of appellation of cost? more than it seems to me, it would be a simple step to hope we're burning and i, and reduce particulate matter pollution on to da mickey fine chopper last composing

just how much pollution to would ovens cause to answer that we visited the cause rural institute of technology hakim did law, is researching fine particulate matter pollution on busy urban streets by comparing them with rural residential areas. littler installed sensors here in the village of students, a beauty. the results are surprising. the rural air sometimes has more fine particulate pollution than can be detected at the neck latoya. in downtown stuttgart, germany is most polluted street. in causeway, of course, phone calls the air and calls her as well as in the new students, a boucher development is actually good until the evening we talk so the next tour shows twice as much pollution at mid day the novel. but the situation changes when the wood ovens i live in the evening and for the air is then more polluted with particulates that can make it into the lungs than it stood cuts,

neck auto. hopefully, we're talking about a factor of 3 over an hour. middle particulars results are confirmed by numbers from the german federal environment agency. the approximately 11000000 wood burning stove in germany. create twice as many fine particles as the emissions of all the cars and germany streets. the pollution gets even worse because the particulates are created, where every one lives a sluggish holiday from one delicious, what's really perplexing now is that these are cars, understandably lead to diesel gate because fraud was involved off to what with wood stoves, fields, where we have lots of harmful emissions and residential areas hot does no discussion with a whole kiner discourse. sure. the need for this discussion can be seen in a variety of areas even at the causal institute of technology. research has looked

at the effects of wood smoke on human lung sales for a few years. a new techniques is much more realistic than the traditional method of filtering out particles, and then dissolving them and liquid and adding them to a cell culture. now, as in the lung, lung cells are aspirated directly in the machine with send outward smoke. just if you similar to and i know it simulates a deeper part of our lung, a foot in the lower bronchial al viola area new law home. when, when you inhale, you've already moved past the upper part of the breathing pathway from this optim huffy at the time, cause particles who had been relieved with cancer, and the aerosol becomes warm and moist. gabon does alice fit it and we're not foolish our up if the fine particular have passed the upper breathing pathway. the remaining toxins reach the most sensitive part of the body deep in the lungs. gases

in audra, fine particulate that are inhaled, are much more potent than for example, foodborne talks in the technique shows that would smoke like until the diesel emissions harms the dna of our long cells. their muscle analog here, every unit like we view other environmental particles is aimed and it's clear we have an acute, quicker faggot of vehicle and there are different lung diseases we focus on them. for the most extreme is lung ancillary. i'm to say and lung cancer is caused by compounds a damage the dna inch deep. and that's exactly what we just showed how saving a big that's why that's for, for him to either get $5000.00 physicists and chemist at the university of roster are looking at what makes would smoke so toxic? they're testing. they are outside of their institute, since it's near the baltic sea, very clean air often sweeps through but when the wind reverses, they regularly find wood oven emissions from residential areas. a new era,

so time of flight mass spectrometer, quickly measures particles and the chemical makeup. the wood smoke is a poisonous cocktail of metals, so it and oxidized organic compounds. the high concentrations of poly cyclic aromatic hydrocarbons are especially alarming. like benzo pirates, which are known for their risk of lung cancer in cigarette smoke. what smoke is responsible for 90 percent of the poly cyclic aromatic hydrocarbons in germany too. i love them probably. but we have a problem that needs to be solved quickly. goes fine. if we're not going to prohibit the stove, that we need flu, gas cleaning, walk, and we won't immediately start the most drastic measures. but we have to gradually improve and 1st get 90 percent in and then 95 percent and then even better filtering rates. but you have to actually start with and that can only be done by

law was with solution for cleaning. the emissions already exist. x of frederick and his team developed a particle filtration system for environmental action, germany that reduces the amount of particles in smoke by 90 percent fireplaces are already available with an environmental label. he would like to expand the system and use a catalyst to cut emissions by 99 percent. although the german government knows about frederick system, ineffective solutions are preferred. chimneys are to be built higher so that smoke is distributed better in the air. 3, you got what the government recently suggested dilutes the emissions and it's not a solution to you. we already did that in the seventy's odd to me. it's scandalous . it's not a solution that we need to reduce emissions. the middle initial air quality in residential areas has been neglected for years because politicians have

concentrated on vehicle traffic plans for the air quality and residential areas are now needed more than ever. that's all for this edition of tomorrow today. thanks for joining us. we'll see you again next time until then. stay curious. bye bye with ah ah, with
