11:15 am
again, the prime minister, renelle grama singer, has been sworn in as acting president protesters are celebrating after his predecessor go to buy of out of pocket, formerly resigned sri lanka. parliament is set to convene in the coming days to choose a new leader up annex it is the documentary, extreme climate events. looking at what future weather could bring to stay with us if you can for that. and it's always more on the website and on social media, of course, t w dot com and acton w news. i'm sarah kelly and berlin. thank you so much for your time. ah ah, i was interested in the global economy. our portfolio g w business beyond. here's a closer look at the project. our mission to analyze the flight for market
11:16 am
dominance. get stood. with d. w. business beyond the memories are still vivid. on may 29th, 2016 disaster struck the village of pounds by and southwestern germany. oh the cut us off herself. i literally watched the flood a wave of debris heading towards me. you flowed and it made a noise as while i should go, i couldn't figure out what it was exactly. then i realize how to show the whole house was shaking. policy passed mayor of han cash film, the catastrophe unfolding in front of him. well said, what are ones in it's in st completely insane. before you know, the emergency services can't do anything. it's not possible right now was out of
11:17 am
the question. my god, save pounds, bottle life financial keel. i was in shock. i couldn't even begin to process what i was saying. missed i'm old. although no lives were lost. the flood left, the village devastated. this is voice horrible. i'm speechless off the robot. people have never seen anything like it. a few years later, germany suffering the effects of a different kind of extreme weather. in 20182019 temperatures rose above 40 degrees celsius in the summer. with no rain for months on end rivers dried up, a disaster for the local environment and its inhabitants. you hutton, last year there was no rainfall here in the region for more than 70 day line. and then in summer 2021. the, our valley in western germany was hit by flash flooding let's,
11:18 am
as you looked at and all of a sudden we were confronted with issues that we'd always thought only affected somewhere else in the world of places like bangladesh. dramatic, whether fluctuations have become commonplace. what does the future hold, and what do we need to do to cope with climate change? ah ah . we begin our research in vintage park in the home secretion. an idyllic spot at the foot of the storm via forest. on june 5th, 20215 weeks before the flooding in the eye valley, a summer storm wreaked havoc here. the picturesque village was
11:19 am
overwhelmed and yolk and bowman's home was among the many destroyed. he and his wife, marianna, will never forget that day, a traumatic experience that's edged in their memory. the basement was completely flooded. the couple had only just finished renovating their home. and now had to start all over again from scratch. they own a heating installation business, so at least they could do a lot of the work themselves near the earth on the farthest, murphy up for if we just got everything finished in here marked mid 5 or 6 years ago, we'd fitted the house out with external thermal insulation for energy efficiency and switched from fossil fuels to an air to water heat pump in side. yet we're done the garden too, and we're actually looking forward to concentrating on other thing suddenly of
11:20 am
august mode of ethnic. i don't it, i'm a little bit when it wasn't to be after hours of torrential rain fall over the local forest hills. the village was hit by a deluge. m a quick liberal, indulging cuz i can't get the images out of my hand is i often look at the photos we talk home. it really got to me soft ah marion bomb and still can't believe what happened the rain and the more that it often burst their banks. but villages that are nowhere near major rivers shouldn't be at risk of flooding. local simply weren't prepared the bomb and still haven't gotten over the experience. bush answered on to host and i was terrified that the front door would break and the water would rush in. from upstairs, we could see the pressure building. we could see the door starting to give way. market was in was guns for the water was up to
11:21 am
here. this year is was the go through and high yard was under water. here oliver was watched on winter book is situated in a valley in the hunts like mountains. the village is nestled in the stone by forest, the source of the watcher that caused such damage. forest landscapes. how fast water storage capacity soaking up heavy rainfall like a sponge. but in recent years, this has no longer been happening as efficiently as it used to. van had pound batter is in charge of the local forestry service. he and his colleague michael fake are going to show us what the problem is. with the flooding inventor book and other religious down in the
11:22 am
valley is linked to the state of the forest. it's increasingly try here where they're digging. even the beach trees are showing signs of drought damage, and beaches aren't usually very sensitive. it actually rained a lot in the summer of 2021. but how much rain did the ground actually absorb? it soon transpires not much at all. with the up you can see it's bone dry has child to become a long term problem. while she shifted the hut and he and derrick yawn in late last year, there was no rainfall here in the region for more than 70 days, improvised. can there cost alone area? it didn't rain for over a $100.00 days. yes. by the 1st of august 2021. there was still
11:23 am
a deficit of over 250 liters per square meter meter. hard to imagine we're given the years overall weather. but it goes to show how severe the lack of rainfall has been in the last 3 years. gosh, last if it's he to in and it's ja allen in ellipse and that i on ninety's vaughn as hard that explains there needs to be 2 months, a steady rainfall day and night to make up for the drought of recent years. he also says that the forest needs to be managed differently in the past water used to be trained from the forest these days he and his team are laying pipes and taking trenches in his own fight in order to replenish the watershed and retained the water. and had collect on the logging roads the aim is to ensure it seeps into the ground across the forest, instead of flying into the valley and causing the waterways there to pursue their
11:24 am
bank. yamazik feeder, better, all hymns, one vote back loi for de la. there are lots of streams here in the soon vase. i'd pull the elbow and make the griffin bert and it was striking how quickly there water level was rose in just a short space of time here in the soon volume. when it rained a massive amount of water collected in a concentrated area, jackwoods, it was pretty frightening in its own boat. one dug positives as far was the song being seemed. when the storm had the forest couldn't absorb the torrential rain, the logging roads were crippled and had to be rebuilt. now, deeper trenches and larger pipes had been put in place to reroute heavy rainfalls to points in the forest where cans he been to the ground. yet i should damn, it does bid these up flush bits impression couldn't. what that does is avert excessive ronald b and allow groundwater to replenish lungs. i'm on the water is distributed slowly
11:25 am
and steadily across the forest floor. i where it's absorbed, who causes in terms of the local ecosystem. it means there's enough water to sustain the forest as a natural resource. again, levens college, head between for as, as lemons. from florida to fulfill moved, it van had found better planning to upgrade the whole forest this way. it's a small but significant way of helping to reduce the effects of extreme weather. the next up on our research trip is in northern germany. every year, hamburrow coast the extreme weather congress. it brings together weather and climate researchers as well as environmental activists. the event aims to reach as many people as possible in the process, raising awareness of climate change and the need to act an urgent priority. not only from meteorologist span priyanka,
11:26 am
but also politicians and the likes of mo jeep la chief, one of germany's leading climate researchers. the 2021 congress was overshadowed by the events in the us valley. can. if we need chain mission, the choice isn't between more or less climate protection, but between proper radical, sustainable climate protection and climate disaster. that's where we're at. dam friday for future. the others fridays for future, i think. and in 2019, there was more discussion of the climate in the environment than there's ever been before. but in 2019 that same year before the pandemic hair toys, we also took more cruises and more flights than ever before. that there's a huge cognitive dissonance going on. and if we really want to get anywhere, then we need to have the courage to change tom. these are the gets in the experts attending the event. i nominate those drought and flooding will become increasingly
11:27 am
common of the ions i to in these a talking fog me with that yet. so i told math st. lawrence in on the one hand there are protracted dry spells as we saw in 2018, 2019. and 2021 and these weren't balanced out and there's always been the occasional dry year. but the about 3 in a row is conspicuous religous or done. and on the other hand of game, we can expect to see increasingly frequent storms and heavy rainfall. i'm so very slow moving storms and flash flooding, but in general, the weather is becoming more extreme, but that's the bottom line of august. you helped him while we were at the congress, we heard about an ambitious research project looking at extreme weather in this way, be in mountains 10 german research institutes are pulling their resources including cloud and precipitation radars and lasers in order to explore the complex processes that occur in the atmosphere, basic scientific research that allows them to better protect extreme weather events
11:28 am
and their consequences. these scientists are waiting for stormy weather. this way be an abs are germany's main storm hotspot and storms are a key aspect of extreme weather. professor americans is a meteorologist with as of yet. laza drama was i. we're going to blow up our balloons, so we'll be ready if a storm starts to breathe in gentlemen. we've already set up the probes. so now we're going to load the balloons in the car, 6 or 7 of them fix it, and then we'll drive right into the store. the balloons are filled with helium, they'll carry small probes into the clouds and will enable the scientists to observe. hale formation occurring during the storm. hill is a typical feature of extreme weather. the team are excited. the clouds are
11:29 am
gathering after hours of waiting. they now need to act fast before they head into the storm. me, her quince visits the lab to check the clouds activity. which direction are they drifting in and is the upwind or convection strong enough to carry the probes into the storm clouds with i'm like, it wasn't like you saw doctor does when he got home convection and shows a powerful lift off. when the rain foam said, falls more or less vertical to the points where the up wind is basically it suppresses the up wednesday. so and that means that the standard lifetime of a single cell is on average 30 minutes to an hour. it destroys itself as it was out of scope with dental. that makes it all the more important to release the balloons
11:30 am
in the right place at the right time. outside the storm salus getting stronger. it's time for the scientists to launch their balloons. right here. positioned inside cuts the propes measure temperature and air pressure, as the balloons drift upwards through the storm. precisely where hale storms are forming inside the cloud. mckerick once can follow the action in real time signal we've got a signal. are we going to use 3 balloons? because the rains got worse, and we hope they'll take off. yeah, i've got a signal off. we go for north orange, stop. have lisa and the probes are inside the clouds taking the pos of the storm as it were. yesterday of
11:31 am
what i thought argument, i thought i fortunately we're not in the middle of the storms out there of 5 centimeter hailstones coming down from the middle and then give our cars are good bashing on the top with it from here me here. constant as team can collect a wealth of useful data, there will help predict extreme weather events. we're planning to visit him in his lab and cast. we're in a few weeks time back inventor book. the bowman's are still dealing with the flood damage. it's the weekend, but instead of putting their feet up, they're hard at work trying to make their home livable again. juergen bowman is haunted by memories of last july, when a gaping hole suddenly appeared in his yard and thought to form alcohol or wild. if there was a power can't, because all the sockets were under water lorne on, it was like being on a house boat or as millions of miles or so what exactly happened as i'm rather the
11:32 am
night of by i the back of over the well this here is an old stream tunnel and there was so much pressure from underneath that it got pushed up with the self supporting structure. and when it got pushed up, it one stone breaks off and the structure collapses. first girl i film shot on his mobile phone shows the thing call that resulted right in front of his house. i 1st love course everywhere with a hole in the garden got bigger, and then as solid wood garden bench got pulled into the current god turned in circles water and was washed away by them. that was the point when i said to my husband, that's rather okay for me now. i'm frightened. my father rightly shocks fool olive enamel offers one. it all disappeared into the hole of the lavon of the hall. the chairs are terra cotta. ornaments of it all. got washed away. what happened here
11:33 am
was nothing in comparison to the disaster in the our valley actually rambled. there was some damage. it's bad, it's a problem, but at least no one was hurt. for glueck gun lynch was wrong because the r valley floods in july 2021 claimed 133 lives with 700 people left injured and 42000 others also affected they were among the worst floods in german history in the space of just a few hours it rained as much as it usually does. in months. the german meteorological service called an unprecedented insurance company, said it was the most expensive weather related incident in 50 years. was damages totaling an estimated 10000000000 euros. does climate change means that such events are likely to become more frequent?
11:34 am
we meet upper geographers trauma, hug and camp. and theresa idle in the village of my shop and the r valley. they are trying to establish the precise water levels that occurred during the flooding. not easy, given that many of the watergate us along the our river got swept away. experts rely on them to analyze and predict flood events. justin, to be a heist warden. what else afflicted your highest warden? a little from his head was peeling this woman canter directly to water levels on the outflow. far exceeded any flooding that happened since records began fivefold women. and you know, we haven't seen water levels like that in recent history. and, but if you look at the history of the, our valley, india, and you can see that in fact, these extreme events did occur. they were very rare, but not on known. overcome in 18 o 4,
11:35 am
there was flooding in the our valley that caused similar damage. done obviously on a smaller scale because at that point and the valley was less built up top that us tired on myself. nice little in about bon here in my shows, the storm swept away a number of houses and destroyed the local train line. complete with most bridges. theresa title and thomas logan can from the university of bon, are using a fyodor light, surveying tool to measure maximum flood heights across the valley. it helps them identify precise watcher levels at precise geographical location. with the brown color of this aside shows just how far the washer road trauma, southern camp has been researching the history of plants in the, our valley. for many years. this time, the watcher here with 10 meters higher than its normal level. the skipped over soc
11:36 am
is equal carbon, the flattened, they can find the fisa falling in deutschland, and they're all flawed. risk matters for all of germany's river hub, but clearly they've not been adequate martin vs. and feel on the basis of these matters. there are plenty of places where you could reasonably decide to put up new buildings. who are these maps don't include historical flow, doesn't hold off on the wall to level record and that are available later back. just 50 or 60 years automotive fulton, that's a short time frame to reflect extreme. then it was ice extreme likeness up to bill . please. maps has since been updated and now include historical data to but what role to climate change play in the i valley disaster was that the ultimate cause in the pump there, i would argue that this is gale of the flood is not necessarily climate change related. it's good and i think it in terms of the frequency. well,
11:37 am
if it's in other words, how often such events occur from vog, you could argue that changing weather conditions, but mean the floods are now occurring more frequently. and that's a consequence of climate changes. climate change increases the likelihood of such events occurring more frequently as demonstrated by a recent study conducted with the participation of the german meteorological service. yet the question remains. why is why they're becoming more extreme? we meet spend prayer at the weather center of germany's main public broadcaster some 35 forecasts are produced for weather bulletins here every day of our music to include as job includes, analyzing maps and figures. not only the t v weatherman has observed that a number of weather phenomena have become increasingly common from the focus until here with math evident that this is the noise here is at 50, not went on. oh, okay. are, you know, here got tells us about the standing ways, phenomenon,
11:38 am
high pressure and low pressure. france that don't actually move. it explains the devastating storms and the r valley does, don't buy it and pounds, but it's highly uncommon for high and low pressure. france to be stationary, but it's become a feature of current weather patterns. and if it was seed for dorms that move, distribute rain across a wide area, but if they don't move, the impact is concentrated in one place. so there's extremely heavy rainfall conflict. if the high pressure front doesn't move than we have the high temperatures and drought, we saw in 2003 or 2018 implement. at the moment we're seeing more frequent standing waves and also more frequent stationary highs and love was to ease of use. so that's a hypothesis that's being investigated right now in law in scientific terms. it's not straightforward. the natural world is always complex, though i am far according to political climate change,
11:39 am
as exacerbating the frequency of standing waves of air meteorologist and storms researcher mckerick once agrees where meeting him at his research institute, rob he said at the center dedicated to analyzing natural disasters, he and his team evaluate extreme weather events around the world. they were among the 1st to compel an overview of the scale of the i valley disaster and the damage it cost me here. cons shows us a map of the area based on satellite data and aerial images. he believes society needs to adjust to the prospect are frequent, extreme weather events. both the hum in deutschland, i extreme weather events occur in germany every year or so. there are floods,
11:40 am
hail storms, winter storms, and vin will live with them and we have to live with them, isn't on the live. oh, and we have to be aware that they happen and know how to respond mostly, but we tend to ignore it, as is typical in our society. once we ignore things we don't like and under, but that can be highly destructive for and then these disasters happened when done through other services or you know, it doesn't cost and his colleagues closely monitor the course. the consequences of these disasters. the aim is to figure out what we can learn from them, and in the meantime, to remain vigilant. let me verify in this icon as i was there via for this one for the lennox. ideally, these are events that canon should teach us lessons for the future. as default when floods occur, it's a mistake to say ok, there's been a flood, it won't happen again that soon. so that's rebuild everything exactly the way it
11:41 am
walks. yeah. that's what's happening in the, our valley. but we know now that places that were flooded are highly vulnerable. c, as in, as in a roughly wouldn't flashing just as helpful versus like owners in the, the all centerpiece in this cons. i, in statistics, don't tell us anything. then i guess another flood could happen next year, or it could happen in 200 years time. i saw sancho. but what we do know is that if such an extreme weather event happens again, casino, then certain spots as such as in short on the our river will most certainly be flooded again, sorry, you want to random than cancer it over fluid mechanics once and his team have also analyzed the flash flooding and pound spot in 2016. at the time it was the most severe flooding scene in germany for decades. again, the cause was extremely heavy rainfall concentrated in one area. within 30 minutes, the village was torn apart. miraculously no one died that many were left homeless.
11:42 am
it also resulted in an unusually vast volume of flotsam and other debris. this quote, it's terrible. as if you're from speechless. you guys have never seen anything like it. the reconstruction work still isn't finished. and for locals, the emotional scars have yet to heal may have hung harsh, helped steer the village through its darkest hour. the road to recovery has been strewn with obstacles and setbacks hash has even encountered hostility. it's been a difficult few years. he's written a book about what happened and travels the country, giving talks on the environmental threats, facing villages like pounds back featuring images such as these
11:43 am
is a good look resume. so to the images are so affecting often, but they inevitably moved people deeply. image and i go, i know i thought, isabel, you couldn't reach them the same way with words. makalya images are extremely powerful. when in march i was on the cortisol, we are still dealing with the consequences. we've got the reconstruction work is ongoing job 5 years later that we can't do everything at once. and it'll take a few more years before we dances. so when it's a long term processing a lot, we have to think in terms of decades in recognition was, was come out little we have to think about how to contain flooding, heart, how to treat the ground, what to do to protect the places at higher altitude where there's heavy rainfall to
11:44 am
her more water stifling stock from the villages. main square was completely rebuilt . the mayor wants to show us other reconstruction work such as the new reinforced walls along the village stream. the reconstruction work has cost the village approximately 55000000 euros to date outside the village. there are now massive debris traps along the narrow slope for a hunk harsh. this is the key element in the protection plan. the huge structure is designed to trap avalanches of debris pouring downstream. weighed all the thong, who's over a foot off in the middle, common reason to know about 50 meters upstream. there's another huge debris trapped
11:45 am
or no covers. what we have to do was was, and it's a long term project to start is try to hold back the water at the source is where the heavy rainfall occurs. so it could be a retention reservoir kind of doesn't look which is problematic up there. and it will be better if the water could seep into the ground like one song as well. to me, the best solution would be to stop farming practices and plant more trees and can to improve seepage potential while as i've of a bracelet for signals. movie coat tough on the land, around pounds bow is extensively farmed field boundaries were removed. they could have helped contain watcher and there are fields and fields of corn. another detrimental factor, because the crop tries out the soil as and for talk that are born come even does less on this. would alls names this week are it, soil can't absorb water and that results in localized flooding. i like to compare
11:46 am
it to baking cake. does this but imagine taking some flower and pouring milk on his lout. the flour is the dry ground with the milk, the heavy rain, as it won't you will be laughed with. is flower on the bottom and milk just floating on top. and once you start needing and the bottom, in this case, the flower has been moistened with a little bit of milk. you can add more milk and it'll soak in better sides and aspect. we'd like to investigate further. at the university of tree are researchers are finding out how trout changes, soil an experiment is underway in the soil science department with samples being sam and to see how well they absorb water their own of again from in a long shot. they were like a tithe of butter soil acts like a sponge in the landscape, storing water over a long period of time, and then gradually releasing it to plant to its surroundings, to lakes and rivers, extreme and extreme weather brought about what climate change has consequences.
11:47 am
long enough, dry soil calls absorb water at the same rate. instead, water just runs off. it was leading to flooding and bodies of water and also to soil erosion and wouldn't have parked in as it was on the soil. scientists want to demonstrate how long it takes a drop of water to seep into various soil samples. first, they add a drop of blue colored water to completely dry soil. it takes a while for the trap of blue water to be absorbed. the soil is so try, it's become impermeable. got 2 more samples. what have you found now so far? come out of the soil. samples are very different. the dryness definitely plays
11:48 am
a big role once good soil containing homeless is partially, it takes dave to moist in again across check. clearly shows that so that isn't completely tried out. can still so cup watcher. but if you're at the dental waltney country, well, you know, into gothic noisy ion. when i was a student in the eighty's and ninety's hawkins, we didn't see this kind of dry stops oil. it was unimaginable. but that's what we're dealing with now. the environmental research and as drought monitor shows the soil effects of up to 1.8 meters has dried out massively on and the rainfall we are experiencing in 2021 is just about managing to replenish the top. so the water supply, it needs to be done, that the sub soil is still parched by the drought of the last 3 years. i got one in
11:49 am
one of the cotton i village and i are try subsoil and flooding. not as contradictory as it sounds, according to the experts. the drought 2018 resulted in reduced harvests and millions of years worth of losses in germany's agricultural sector. rivers dried up, such as the ties them near fryeburg, which closed from the black forest industry struggled with a shortage of raw materials and even gas was in short supply. the media was full of doomsday scenarios here, man and of manners it course and feel, in my opinion. it's a mistake to focus on all the doom and gloom. when the media goes on about the apocalypse and this crisis and that crisis season, we end up. so overwhelmed that we lose all our courage and think there's no point trying to do anything about it. what, when, in fact there are so many groundbreaking project is skipped zoar feel launched on
11:50 am
project groundbreaking projects that prove we're not powerless against extreme weather, such as the live spec, organic farm on the done us back ha range and highland fights founded by young people. but it relies on water and that's in short supply up here. jeanine harbor works turn shore the soil as as permeable as possible, so long as it can still absorb watcher a can withstand extreme rainfall, fluctuations photographer and gop. assume that yawn all stock a whole in 2014 the was severe flooding hair in the region that caused millions worth of damage by the marshall back stream overflow. it could be the most of the areas around it all agricultural fields that are compacted and where the water can't see pin easily, and the soil is homeless deficient and being on flooding sweeps away. the entire top soil and entire villages are hit by mudslide alpha buffington. the young
11:51 am
organic farmers are planning to revitalize their land using a special technique. first, they analyzed local rainfall patterns. up in the blue line on the chart show in which direction the rainfall is likely to flow. shanina harbor and her colleague have drawn red lines where they plan to dig ditches that will help distribute the watcher across the farmland. this technique is called key line water management of a kind of good, but they're concerned about the amount of red in their chart which indicates just how try the region is. ah, they're keen to show us how effective their strategy is against why they're extremes. first they used to how to take their ditches. before switching 10 excavator they want to test how the key line water
11:52 am
system works. they take their trenches with a slight gradient 1.5 percent to prevent large volumes of water from flowing too fast. i had some an experiment on average z and we conducting an experiment to illustrate how the water that a mass is during heavy rainfall. a vendors can be distributed over the area and conceit into the ditches laid according to the queue line system missed. instead of flowing down the slope, guaranteed and causing flooding in the valleys and calmed on the to zang funding for an inter book our water from the top a graphical depressions where a collections could be diverted to the mouth. so where the ground is dr. office google just doesn't do talking, spin owned jeanine harbor uses the water tank and a hose to simulate heavy rainfall. come
11:53 am
a mark. many flood obviously rain as moth localize. but the experiment shows that the dish absorbs the artificial downpour as planned for the water, then flows along the key line towards the elevation. mm it looks simple, but it's an intelligent way for farming to adjust to the challenges of climate change. a heavy rainfall and drought don't just adversely affect rural regions, but urban areas to villages, towns and cities also. nita just says weather experts fan trigger. the problem is not really out dusk staton lamps, if massey fortified and his own globular. for ziegler problem, of course,
11:54 am
is that cities and surrounding areas are very different because cities are built out at the close. nobody show that heat waves in the likes of colona frankfort line, make them 9 degrees hotter than surrounding areas of cities such as cosgra, are also likely to see a significant increase in temperature. that's when this poses an additional problem . dam. it effectively makes the city a completely different climate zone. so we need to think about how we can make cities greener and less dry ella, with more greenery, more water cooling by evaporation to curve extreme hate disease, extreme hits of ugly to devin urban planners. and cas were, are already looking at ways the city can tackle climate change. one of their 1st projects is the redesign of the plaza site, the main station it's set to become much greener, which will not only make it more attractive, but also how protect the city from getting too hot in english didn't give this
11:55 am
lands. mr. phillips was eager to our cities are very built up, that the idea is that instead of being drained off to rivers by leading to flooding, water is retained in the cities a faster. that's what's called a sponge city present. man, i had a family that 1000000 auto as a landscape architect and urban planner. his munich based team was awarded to re design contract. construction is about to begin gab. mm hm. yeah. it's a target love to another them on. we're experiencing more very hot days or less, but also more heavy rainfall by lunch off. that's problematic enough in the countryside layman, but it's even more extreme in the cities on the 1st home. it can get unbearably hot in cities like causal were in the rhine, valley and tile. we have to cool down our cities and at the same time, mitigate the heavy rain for which is becoming more frequent and retain the water in the cities up. some is on the flutter, so it so high trees,
11:56 am
fountains and miss spray will help cool the plaza father walkways are permeable. water is a key design element ratliff, near display. we need to use every project to boost water retention in cities. but for plans, for cooling purposes, explaining, we need to convert cities to what's called green and blue infrastructure, one cost coin adopting the sponge city concept to meet the climate change challenges of the future. with innovation is essential. forest, her band have hamburger in the san vite is also looking for creative ways of maximizing watch her retention. just like roy on auto and kassawa. his name is to capture, distribute, and use watcher as efficiently as possible. mm. that then tried to buy visa.
11:57 am
my number is that we cannot either from what is crucial is that we make the call function of the forest or the focus of our efforts with user to boost water retention and increase it sponge function v cronin v can now does a shameful tian shy gun ah, there are grounds for optimism. we just need to adapt to changing weather patterns . that's why pounds, but mayor frank hash tells people as he tours germany, raising awareness of flash blood was fever. this morning. we need action and improvement across the board. don't joined us. he said, i do believe that can work, but a lot needs to happen before people like yard and, and marianna bowman are safe from the threat of flooding and the villages of into block pounds bah, and elsewhere. after a lot of hard work,
11:58 am
