oh, man has no limits. love is for every body. love is live, love matters and that's my new podcast. i'm evelyn char, mom and i really think we need to talk about all the topics that north divides and deny that when this i have invited many deer and well known guests. and i would like to invite you to an in drought and flooding. extreme weather events are becoming ever more frequent all around the globe. in the united arab emirates, they've been trying to be increasing heath for years with rain making techniques, but doesn't work. at the polar ice caps, glaciers are melting out

a terrifying speed. and the glaciers are in the mountains to reset is of battling to collect the ancient ice, which is packed with climate history before it disappears forever. ah, welcome to tomorrow to day the signs show on d. w. them and they in hindu kush region, is sometimes referred to as the 3rd pole. there are more glaciers in this region than anywhere else to part from the north and south pole. they feed rivers with by to water, but the big melt is even affecting lofty innovations leading to flooding and land slides like here in pakistan. in the ups global warming is also hitting hot in summer 2022 glaciers frank more quickly than ever before. a

team of scientists is trying to preserve the informational climate history that they contain by taking ice coal samples in the else on the austrian italian border . it's 8 in the morning in the austrian alps. glacier researchers are heading up the vice. they spit the mountain a peak, that's 3500 meters high. they want to collect something valuable before it's too late. ancient ice cores. the ice on the vice, they shits a mountain is getting thinner. nice up. there is only 10 meters thick and 6000 years old. when it disappears or melt will lose 6000 years of climate history . uncovering the ice cores at heights of 3500 meters requires special equipment that's delivered by helicopter. the helicopter makes

multiple trips to transfer equipment and the research team to the summit of the vice they spitzer. the helicopter flies almost 1000 meters into the air over the glacier ski resort. but the researchers are interested in the ice from these normal glaciers, which are also known as temperate glaciers. there on a search for what's known as a polar glacier glaciers are formed high up in the mountains where the snow never melts. when it snows again, the old snow underneath it is pressed to ice. the majority of glaciers in the alps are temperate or warm based glaciers. that means the temperature of the ice is just barely below freezing. under the ice itself is a layer of water which allows the glacier to slide into the valley. that's why its ice is rarely more than 100 years old. ah, polar glaciers,

like the one on vices. a schmidt's on the other hand, don't move at all. it's ice is a few degrees colder than that of temperate glaciers and their frozen solid on the bottom. polar glaciers are rare in the alps. up here at heights of 3500 meters, a 6000 year old glacier ice. for now, at least, researchers fear that in 10 to 20 years, all of it will be gone. temperatures up here can be as low as minus 15 degrees celsius. tough conditions for spending an entire day in one spot. strong winds complicate their work as well. the advantage of it we are currently building the wind fans so we can work in areas that are protected from the gus for that. so we need these pieces of wood to keep it stable. that

there's more than a meter of snow on top of the glaciers ice. it has to be removed before drilling for the ancient ice cores can begin. the 5 person team needs about an hour to prepare everything. they opened the wind guard in the tent, set up the required devices, and prepare the bore hole. up here from here out, the sun has to work for us. when it goes away, we lose our power source. and so we do have a battery, but it doesn't last for the drilling process happening. that's why our drill is attached to a solar panel of solar charged controller and to battery can my slow thing we can actually get started. now i, initially the drill goes in easily, but 1.5 meters down. it's already more difficult than with

a miss and south. i really have to watch out that the drill doesn't get stuck and pull it out on time exit at austin. or north was an army there shows how much power the drill is currently using. if it suddenly swings upwards, the drill must be removed immediately. otherwise it will freeze the ice cores have layers that are similar to tree rings. light airy eyes alternates with dark eyes full of dust, soot, an organic deposits. some layers contain dust from the sahara desert or volcanic ash. the age of the ice layers can be determined by historical records. yet seen via old hair, with somewhere at the beginning of the modern era,

at the end of the middle ages, the highlands that was settled at the time was soon left behind because another 30 meters of ice formed in the course of the little ice age. and the whole of europe was cold, it was warmer, the full em, but we know that there's been ice at this location permanently for 6000 years. there were places here even during past one periods of the researchers try to recover as many cores as possible. air in organic material from past centuries and millennia had been preserved in the ice and will later be analyzed in the lab. his elbow, he oldest ice we're finding, is at the very bottom, and we're most interested in just how old it is. now i have to say really, that it's the replaceable priceless if, as soon as it's gone, it's gone, you won't be able to collect it any more, you call it, and there are

a few places where you can find ice like it on them. so we're collecting it now to enrich our knowledge. there's a threat does, does in it there, which means that we're possibly quite close to the bottom already. well, i am going from every piece, no matter how small is carefully bagged. after about 3 hours of uninterrupted drilling, they finally reached their goal. oh, wrong. the last ice core is brought up to the surface. again. it's 6000 years old. and now the scientists have to hurry again, the helicopter is returning at 4 p. m sharp. they carefully low the ice cores into cold boxes. keeping them cool is essential for preserving valuable knowledge about the past. them in the veil, beverly and we'll see which epochs of the last 6000 years were favorable for

glaciers and which were unfavourable. and then we can better classify today's climate change. because the basic question is how unusual are the processes that we observe today? i have, they occurred before in the past no matter where their past room epochs on if so, how long were they, how warm with a and we expect answers to these questions here and lot of these are for a few ice cores will be stored for posterity so that future scientists can study them with even better analytical methods. these scientists are also drilling deep into the past. in the c bed knows event article, they did the dna that dates back 1000000 years. d n, a analysis of the sediment can reveal what lived in the war to win and provide climate information. diatoms, for example, in wound climate phases,

l t species were able to breed successfully and populate the c and large number being deposited over thousands of years on the sea bed. analyzing the drill cause can also help researchers better understand how human induced climate change might affect the waters of antarctica in the future. one thing is clear as the waters war . many glaciers in antarctica are melting, including the doomsday glacier. this is the weights one of the world's largest glaciers. it's located in western antarctica and covers 192000 square kilometers. that makes it roughly the size of senegal, nickname, the doomsday iglesia, the melting of it would lead to numerous flooded coastal cities. an international team of researches has now mapped the retreat of the ice giant over the centuries. the results of worrying to say the least,

the glazier is falling apart much faster than originally thought. so wait, leisure itself could contribute around 60 centimeters globally to sea level rise. the problem is in fact that waits her such a central position in the western pike. i see that it's retreats and eventually collapse could cause the whole western. i think i she to collapse and that would mean more than 3 meters of sea level rise. the threats glazier is part of the marine ice sheet. unlike some other glaciers on dry land, weights is grounded in the sea bed. one part called the ice shelf, floats on the water, and that's the problem. as a result of our greenhouse gas emissions, the water is getting warmer. as it heats up, it melts the glee caea from below. in a normal situation,

the ice coming down from the ice sheet is in balance with the ice last by melt. if the system is not in balance, then there's more ice melting. and the grounding line is retreating inlet because of the particular geometry of the earth, weight glazed, and also the rest of arctic ice heat. it is getting deeper and deeper towards the inland areas. and that means that the whole system is prone to a so called my read ice seat instability. scientists have found that in the last 30 years, the point where the ice starts to float retreated, 14 kilometers, further inland. much of the ice that used to rest on land is now floating on water . all has a ready melted research is one that we might now have reached a tipping point, where large parts of the ice shelf might simply collapse. so the ice shelves,

half a so called buttress, inc force, that means they're floating on the sea, but on the sides and sometimes also in front. they are in contact with small islands or little hills on the site. and this gives some restriction, some property to break the flow of the ice. so if the ice self disappears than this, but twisting effect will become smaller and threads later will most likely increase its flow velocity. and sweeps isn't the only iglesia melting. scientists estimate that by 2100 sea levels may rise by around a meter or even more said the millions of people around the world. we live in coastal areas that's really bad. knees rising sea levels means that they will be hit by more frequent and more extreme floods. so it's vital to take immediate action scientists say. and the only way to do that is by

reducing on greenhouse gas emissions as drastically and quickly as possible. hello, harris haynes and select those are another spin off effect of wilma oceans and we'll may data indicates that climate change is also making them longer lasting and more destructive. hurricane ian hit the gulf of mexico particularly hot in september 2022 for us. seems especially vulnerable to louise kara from panama, wanted to know line blue wire. there's so many hurricanes in the usa. hurricane are tropical cyclones. their extreme wind speeds and heavy rains can cause massive damage

and strike fear into the hearts of many hurricanes can reach a few 100 kilometers in diameter and rage over the same spot. for hours. they form near the equator, over large bodies of water, warm to 26 degrees celsius or more only storms that develop over the atlantic or over the eastern and central pacific are called hurricanes. the hurricane season runs from june until late november. that's when large amounts of water evaporate and rise with a warm air. as the earth rotates air masses, north and south of the equator, are deflected by what's known as the cory oldest force. these masses start to spin, producing a swirling cyclone. at its center is the eye of the hurricane,

a wind and rain freeze on with few clouds. when such, i clones form in tropical or sub tropical zones, they usually move in a westerly or northwesterly direction. in the atlantic, this means hurricanes off and head toward the east coast of the us, where the gulf streams warm current only serves to fuel. the storms. fury in 2017, a nasa satellite captured this image of 3 hurricanes, approaching the southeastern united states from space. we can now observe in great detail how hurricanes form and where they travel the path taken by all atlantic hurricanes in 2021 can be seen here. several hit the u. s. east coast. yet the west coast escaped largely unscathed.

most hurricanes headed west into the open ocean. southeast asia has tropical cyclops, too. though here there call typhoons a 3rd of all such storms occur. they're making it the world's most affected region. people have always long to change the course of stores or manipulate the weather in other ways in the us. the 1940s ushered in a new era of weather modification. in 1947. these men were getting ready to fly into a hurricane. ah, they were the team behind project, cirrus, a us government initiative to try to manipulate a hurricane vincent j shanpa headed up the team in his

newberry tree, he discovered that he could modify close by adding dry ice. with this knowledge, his team flew 3 i croft directly into a hurricane. they dropped 36 kilos of dry ice into the stone and they reported seeing a change in the clouds. ah, the method was called cloud seating. it mimics what happens inside rain clouds. the water vapor in the air condenses to form drops with the help of tiny particles like dust or ice crystals or artificial seating agents like dry ice or salt. when the drops get you know, they rained down. the big hope is that cloud seating can bring rain to regions

where it's desperately needed in the desert state of the united arab emirates. they've been trying this for years. okay, so under smart is busy fitting his plane with an unconventional payload. 48 felt cartridges in the hope of making the clouds crying. he's a rainmaker. and today he fancies his chances. the 57 year old swede makes one last check before takeoff. he has just 3 hours to get his charge into the clouds. above the arab emirates, a challenging task. the club seating, noticing it is all for a person like me because i spent most of my career trying to avoid clouds for the comfort of the passengers. whereas now are fly madness certain are inside of the cloud, but just the edge soviet and it can require to turban lift off from the desert into

the clouds with hazy visibility and a temperature of 35 degrees celsius. it's a mission with an ambitious goal. water is scarce in the emirates, but consumed in abundance and glitzy cities like dubai. the construction industry is booming, and every year around $800000.00 people move to the oil rich federation. despite rising temperatures and falling ground water levels cropped, cultivation and the emirates is becoming increasingly difficult. sellers are hummadi thought he'd try his hand at farming when he retired from his former job. 5 years ago. the 63 year old now growth figs, pomegranate maze, and dates on his small plot of land on the outskirts of dubai. he which is the water from a well 300 meters deep. every year the level drops further. he can water his fruits

for a maximum of 3 hours the day. he tells us that many whither in the blazing heat and cannot be sold within sir la l. her. marty often looks to a higher power for help of all. i'm a little early, pray for rain, imploring pure might to provide us with water without water. a man is worth nothing . my associate almost wishes at the national center for meteorology in abu dhabi. scientist said, trying more down to earth, mother's viola ackman, i kamali, presented the current weather data to the team, and ventures of forecastle as to which clowns will appear when and where would he for with a cloud. so by no means rare over the emirates, but far too often, they don't bring rain with their full propeller plains. the scientists therefore shoot sodium and potassium chloride into the clouds. the salt particles bind water become heavy and rain down. interestingly,

the scientists say their activities don't lead to less rain elsewhere. they say the results from 15 years of practice are encouraging. we has done recently a study about the, the enhancement of frame full of the enhancement of frame full. and it has turned out that the cloth seating actually in the u. e. increases the rainfall of about 23 percent on an average. on best situation, it can reach up to 35 percent off in house single rainfall. heavy clouds are gathering in the sky over the gulf. it's important that things now proceed quickly and you'll augment, i'll kamali radios and does model and gives him the coordinates of a promising cumulus cloud. the pilot picks up the trail and steers towards it. timing is everything now you're so

many things going on at the same time. you have to fly the airplane. i have to navigate the raw, the cloud, so that in time and space your the correct place. but you must also navigate in relation to the actual cloud formations one command and does march fires 4 rounds. slowly turning as he doesn't in the control room. the meteorologists are already looking for the next cloud that he can head full. he seeds up to 20 in 3 hours. success often follows very quickly, happy moments that the whole team i am convinced this technique works and i'm not saying that there might not be some other method that is conceived in the

future, which is possibly a better method. but at the moment, i believe in what we are doing. oh, rain is often seen as a blessing in the desert weather for home. and i have fascinated salon al hummadi since he was a child. whenever he can, the farmer from dubai, films, the rain, the devout muslim, considers it legitimate man, not to allah makes it. no manila, moran doesn't forbid science. on the contrary, it's important that people find ways to invent things that are of benefit humanity . oh, we ashad them, fell in the past. people didn't really think too much about clouds. you look at them a much of a, it's a necessity. why we have to look for ways to get more water on a job. then deliver them above critique, say the emirates, multi $1000000.00 seating program is unscientific and that its apparent success remains unproven. claims rejected by the head of the national meteorology center.

he also points out that d sullen aging sea water is many times more expensive than cloud seeding of it is a success and we encourage yeah, a lot of people will be involved with the world methodical organization or all the m o. ready the outward of this project will be as ambled for them. many countries know they are going to approach us and get the benefit of this year. out of this, this project. and those man climbs out of his plane exhausted, but happy that he fired off 40 of his cartridges successfully feeding full clouds. sure, sure. today was a rainmaker. yes, i can proudly say so. that report to see. and as mobs, expeditions might not be able to stop climate change or resolve the lack of water, but they can at least generate a little more of that precious commodity. re if i what, what is read,

why i gave you hated to use a science question about space or something here and i then send it to us. and until next time, take your ah, with ah, with

who a burger today should be total on you let us tomorrow. oh, farming in the future. food entrepreneurism, farmers are experimenting with more sustainable meal concepts. but are there seems taken root food for everyone? close up. 30 minutes on

w. ah scott, it's it's, it's all to say what grade level with who every jenny is full of surprises. we've gone all out to give you some test one day and in the foot of the right people. i'm in your northernmost count to play with 3 times one very much a line dw channels,

your guy to the special hotspots in germany. it recognizes where exactly it was fun and i learned a lot of our culture history, all their d. w travel extremely worth a bit. ah, i have been friends, i have been beaten. i have been taken straight it because we try to to show the face of mafia all over the world. environmentalists are in danger. the enemy, ruthless corporations corrupted, government agencies and criminal cartels. with a desire to be targeted, environmentalists in danger starts october 29th on

d. w. a . ah, this is the w news live from a generational task that must start now the words of germany as chancellor actually opened a conference on the reconstruction of ukraine following russia's invasion. the talk is of a program on the scale of the marshall plan to how realistic is that goal.
