DW Extreme Climate Events July 17, 2022

Dominance. Get us 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 flight away from debris heading towards manning the floor and it made a noise. As well as hunger, i couldnt figure out what it was exactly swiftly than i rayleigh, had to show the whole house was shaking. Policy passed, mayor hung cash film, the catastrophe unfolding in front of him once in. Its in st. Completely insane. Before all the Emergency Services cant do anything. Its not impossible right now out of the question. My god. Save pounds, bottle life financial. I was in shock. I couldnt even begin to process what i was saying. Mr. Arnold. Although no lives were lost, the flood left the village devastated with voice horrible. Im speechless off the rubble of 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 days line. And then in summer 2021 the, our valley in western germany was hit by flash flooding. Lets as you looked at and all of a sudden we were confronted with issues that wed 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 overwhelmed and yolk and bowmans home was among the many destroyed. He and his wife, marianna, will never forget that day, a traumatic experience thats 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 at near the olive on the fathers commercial poor. We just got everything finished in here with 5 or 6 years ago with fitted the house out with external thermal insulation. For Energy Efficiency and switched from fossil fuels to an air to water heat pump inside. Yet we done the garden too, and were actually looking forward to concentrating on other things. Agnes, im loaded that make her wanted. I love that, and that was it wasnt to be after hours of torrential rain fall over the local forest hills. The village was hit by a deluge. M a quick trip alone doesnt come. I cant get the image is out of my hand is i often look at the photos we took. It really got to me stuffed ah, marian bomb and still cant believe what happened. The rain and the motor often burst their banks, but villages that are nowhere near major rivers shouldnt be at risk of flooding. Locals simply werent prepared the bomb and still havent 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 from africa. Was in was guns for the water was up to here. This year was a gun. So anti yard was under water here oliver there was watched on winter book as situated in a valley in the hunts like mountains. The village is nestled in the stone by a 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, invent up or can other religious down in the valley is linked to the state of the forest. Its increasingly try here where theyre digging. Even the beach trees are showing signs of drought. Damage and beaches arent usually very sensitive. It actually rained a lot in the summer of 2021. But how much rain did the ground actually absorb . What if soon transpires not much at all . With the up, you can see its bone dry. Has child to become a long term problem. While she shifted canada the hut and he and eric yawn in lets last year there was no rainfall here in the region for more than 70 days. Improvised. Can there cost alone area . It didnt rain for over a 100. 00 days. Yes. By the 1st of august 2021, there was still a deficit of over 250 liters per square meter meter. Hard to imagine a given the years over all weather. But it goes to show how severe the lack of rainfall has been in the last 3 years. Gosh, last if its either in and its been yarn in ellipse and that i on ninetys 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 that collects 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 bank with all your. Hm. Josefina becker, all he am the one vote back loy for de la. There are lots of streams here in the soon vas idol, the elbow and the griffin box. And it was striking how quickly their water level was rose in just a short space of time. Here in the soon vase just when it rained a massive amount of water collected in a concentrated area, jackwoods, it was pretty frightening. Laugh in his own boat. Wonder good positives as far was the song being seemed. When the storm head, the forest couldnt absorb the torrential rain. The logging roads were crippled and had to be rebuilt. Now deeper trenches and larger pipes have been put in place to reroute heavy rainfalls to points in the forest where it can sleep into the ground. Yet i shall damage dust be these are up, flush bits and question can what that does is avert excessive ronald b. And allow groundwater to replenish lungs. Im on the water is distributed slowly and steadily across the forest floor. Ice where its absorbed, who causes in terms of the local ecosystem. It means theres enough water to sustain the forest as a natural resource. Again, leaving squalid happenings as, as live in florida to fulfill it than had found back as planning to upgrade the whole forest. This way. Its a small but significant way of helping to reduce the effect of extreme whether the next up on our Research Trip is in northern germany every year hamburrow coast the extreme, whether 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 spend praga, but also politicians and the likes of mo, she play chief, one of germanys leading climate. Researchers the 2021 congress was overshadowed by the events in the us valley can if we need chain mission, the choice isnt between more or less climate protection. That between proper radical, sustainable climate protection and climate disaster. Thats where were at. Dam friday for future. Theres fridays for future lighting, and in 2019, there was more discussion of the climate in the environment than theres 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 theres a huge cognitive dissonance going on. And if we really want to get anywhere, then we need to have the courage to change. And tom, these are the gets in the, the experts attending the event are unanimous. Those drought and flooding will become increasingly common of the islands. I to even be the talking files will be with us yet. So i told math say line saying on the one hand there are protracted dry spells as we saw in 2018, 2019, and 2021. And these werent balanced out, and theres always been the occasional dry year, but the about 3 in a row is conspicuous vilegas were done. And on the other hand of game, we can expect to see increasingly frequent storms, some heavy rainfall. Im so very slow moving storms and flash flooding. In general, the weather is becoming more extreme, but thats the bottom line. I used to help implement 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 and the atmosphere, basic Scientific Research that allows them to better protect extreme weather events and their consequences. These scientists are waiting for stormy weather. This way be an abs are germanys main storm hotspot and storms are a key aspect of extreme weather. Professor americans is a meteorologist with other laws and from i was i began to blow up a balloon, so well be ready if a storm starts to breathe. Gentlemen, weve already set up the probes. So now were going to load the balloons in the car, 6 or 7 of them, 6 and then well drive right into the store on the balloons are filled with helium, theyll carry small probes into the clouds and will enable the scientists to observe hale formation occurring during the storm, hill is a typical feet of extreme weather. The team are excited. The clouds are gathering after hours of waiting, they now need to act fast. With me, before they head into the storm, me, harry 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 id like to watch like you saw doctor does when he go convection and shows a powerful lift off. When the rain foam said, falls more or less vertical to the point where the up wind is, basically it suppresses the op winds. So, and that means that the standard lifetime of a single cell is on average 30 minutes to an hour because it destroys itself. As it was. He says, cup would get all that makes it all the more important to release the balloons in the right place at the right time. Outside the storm cell is getting stronger. Its 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. Weve got a signal. Are we going to you 3 billings . Because the rains got worse, and we hope theyll take off yet, ive got a signal off we go, or north orange stop. Have lisa and the probes are inside the clouds, taking the pulse of the storm as it were here for you. What are your thoughts . Are to make life i fortunately, were 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 of it. From here me here, concent his team can collect a wealth of useful data. There will help predict extreme weather events. Were planning to visit him in his lab and cast her in a few weeks time. Back inventor book. The bowmans are still dealing with the flood damage. Its the weekend, but instead of putting their feet up, theyre 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 cant because all the sockets were under water lorne on. It was like being on a house boat, her as well and the miles for so what exactly happened as im rather the night of but i was back of urban. Well this here is an old stream tunnel, and there was so much pressure from underneath that he got pushed up with a self supporting structure. And when he got pushed up, it one stone breaks off and the structure collapses. Briscoe, a film shot on his mobile phone shows the thing called that resulted right in front of his house. I 1st longer close. Ive worked with a hole in the garden, got bigger on there now, solid wood garden bench, got pulled into the current, got turned in circles, water and was washed away. So by that, that was the point when i said to my husband, just roger, okay, have him is now im frightened. One for right. The sharks flew aloof. Enamel offers one. It all disappeared into the ho of the lavonne of the hall. The chairs are terra cotta. Ornaments of it all got washed away. What happened here was nothing in comparison to the disaster in the our valley actually rambled. There was some damage. Its bad, its a problem, but at least no one was hot. Glue gun wrench withdrawn from the r valley floods in july 2021 claimed 100. 33 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 it unprecedented. Insurance Companies 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 . We meet upper geographers trauma, hug and camp, and theresa shed idle in the village of my shot and the i valley. They are trying to establish the precise water levels that occur during the flooding. Not easy, given that many of the water gauges along the i river got swept away. Experts rely on them to analyze and predict flood events. Give us a standardized warden. What else . The of presidio highest warden have a little from this here. Bush pianist, 11 counter directly to water levels on the outflow. Far exceeded any flooding that happened since records began fivefold human. And you know, we havent seen water levels like that in recent history. And 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, there was flooding in the, our valley that caused similar damage. Obviously on a smaller scale because at that point and the valley was less built up top that was tied 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 has been, are using a few other 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 thomas sudden 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 a horse of his equal cotton. He flattened the can find a fist of falling in deutschland, and theyre all flood risk matters for all of germanys river. But clearly theyve not been adequate latin vs and feel on the basis of these matters. There are plenty of places where you could reasonably decide put up New Buildings who are these maps dont include historical flow, doesnt hold off on the wall to level record and that are available, laid back just 50 or 60 years itemized. Fulton, thats too short a time frame to reflect extreme, then it was, i say, emma agnes 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 pump there, i would argue that this is gale of the flood is not necessarily Climate Change related. Its good and i think it in terms of the frequency. Well, if its in other words, how often such events occur is from vog. You could argue with changing weather conditions, but mean the floods are now occurring more frequently. And thats 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 theyre becoming more extreme . We meet spend prayer at the Weather Center of germanys main public broadcaster some 35 forecasts are produced for weather bulletins here every day of our music to include that 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 farther central. Here of us must evident. Yeah. Does 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, High Pressure and low pressure. France that dont actually move. It explains the devastating storms and the r valley does, dont buy it and pounds, but its highly uncommon for high and low pressure. France to be stationary, but its 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 dont move, the impact is concentrated in one place. So theres extremely heavy rainfall conflict. If the High Pressure front doesnt move than we have the high temperatures and drought, we saw in 2003 or 2018 implement. At the moment were seeing more frequent standing waves and also more frequent stationary highs and love was to ease of use. So thats a hypothesis thats being investigated right now in law in scientific terms. Its not straightforward. The Natural World is always complex, though im far according to pick a Climate Change 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 wo
