class 7 months before rush tech to crane a field team documents daily life, the town. how are the people who are dealing with the growing tension? they change their world frame hold on. we are with you. currently no enemy inside. starts drawing on dw, the wind, wild fires meet on favorable wins. heavy smoke can cross the boss distances like in north america. in early june, new york became shrouded in smoke due to forest buyers and neighboring canada. we need to learn to equip ourselves to live with the shop, reality of climate change and its consequences whether anomalies heavy rains and storms shrinking places on the death of corals,

we still have time to prepare the hello and welcome to tomorrow. today dw sign show the kind of crisis is having a devastating effect on corals. a recent study suggests that 90 percent of carlos b c's will soon disappear. and yet, these complex eco systems are crucial to our planets around a 1000000000 people in asia alone and source of food directly from re we'll straight in government has declared its intention to invest billions in protecting the great barrier reef. well, marine biologists have been trying to grow carlos full some time measuring 350000 square kilometers. the world's largest carl reef is almost the size of germany, the and it's

a unesco world heritage site, a treasure without equal and one we're in danger of losing last strategy is great. barrier reef. the australian institute of marine science board games is leading efforts to prevent the total collapse of the reef. marine biologist is passionate about the work being done. my day to day is facing this press. one, what happens to the system? however, i don't think that that causes me to lose heart. i still get to go out and see the great barrier reef and speak to that healthy and be useful. and there's so much diversity that still west protecting the countless change simulate the living conditions and the reef. carlos are sensitive creatures, water quality,

light and temperature, or major factors in their survival. what happens when those living conditions change and become more uncomfortable for the roofs? residents? change conditions. very bleaching is the phenomenon that they fear most because they've suffered too often in recent years. if the water gets to the cold shirts, algae, these algae are not only responsible for the chorus, brilliant colors, they also provide the coral with nutrition. if the algae disappear, the car will die. can visa effects be directly traced back to us humans? unfortunately yes, yes, they are suggesting that when manipulating the environmental conditions and as a response,

those conditions often most stressful like and these conditions have a name, climate change, australia is feeling its effect on land and sea. they heat the drought last harvest and the apocalyptic images of the burning forest. at the same time, cities, villages entire landscapes are completely under water. extreme events have become normal. environmental activist crystal foth not says that's reason enough to be scared. i think the message is becoming very, very clear and more and more clear each year which is actually quite devastating that it has to come to this for, for some instructions to open their eyes. and for governments open their eyes at the true cost of not acting on climate change. no. where is that more apparent then that's a great barrier reef. form mass of carl bleaching. some 7 years have caused such a massive damage that unesco is threatening to revoke its world heritage site

status. australia is reputation and a lot of money are at stake. the re isn't in more or less academic assets, providing $70000.00 jobs. most of them in the tourist industry, dining instructor nadine who came here from germany 9 years ago and also conducts research dives. yeah. yes. nice know for the various steps to see how many carls there are in any given location. how many different types, how many have died? how much out g is still that. and whether there is any coral bleaching the send the entire data to the marine biologists of the english institute, closing the circle of those committed to protecting this unique ecosystem. to the very end. the psych shows also poses

a threat to read and they will likely be more of them again this year. in may 2023 . the road me to a logical organization. won't that i'll nino is looming again in 2019 with this regularly recurring climate phenomenon cause huge hurricanes in the pacific. how do storms move across the globe? that's this week's question from rodrigo, mankato in ecuador. trump because sight close across the equate bringing torrential, rain and battering wins. tropical psych plans can inflict a numerous damage. they usually leave a vast trail of devastation in their wake. some stones and more than hundreds of kilometers in diameter and compound a single area for long periods of time. that's why people feed them tropical

st clones full of a knowledge bodies of water around the equate to the water has to be at least $27.00 degrees celsius. so that large amounts of it can evaporate and rise with the woman. because the us is basically a spinning bowl, the m s is north and south of the equate to get deflected. they then begin to spin and form huge also sees a consequence of the so called korea, unless folks don't be equate to this force is very small. that creates a string around 600 kilometers wide that sped from the destructive stones. the macareola's force causes site plans north of the equate to, to spin in a counter clockwise direction. well south of the a quite tips they rotates in the opposite direction. the since

1979, no tropical site clothing has ever been observed crossing via quite so. but that doesn't mean it's impossible. in 2001, a slight claim came within a 160 kilometers at the equate to close to them as a before the recent decades have shown that tropical site close, i'm moving further and further away from the equates at towards the us holes. we can only guess what might happen if a slight clone, which across the equate sense it would most likely lose its angular momentum and end up as whole task. because the courier, this false works in the opposite direction. on the other side of the eclipse, the blood is red. why do you have a science question?

send it to us as a video, text or voice basis. if we answer the shows, we'll send you a little surprise as a thank you. come on. just on the now to the mountains, according to one recent study, nearly all of our time it's mountain glaciers will have melted by the end of this century. drinking voice, it will be scarce. nope, just near the mountains themselves. and sea levels rise in zurich, switzerland, a team of scientists, is researching massive ice loss in the else the glacier as m. e l are disappearing without immediate time in action. nearly all of them will have melted by the end of a century. zurich beast,

she ologist medea's host. there's only a little hope left to be scholars and ship. it sailed, at least for the small and medium sized glaciers, for the bigger ones, it's still not too late. but at e. g. h zurich, whose researches the development of alpine glaciers, particularly what ecological social and economic consequences their melting will have at the global, regional, and local levels. the fact that tourist attractions are disappearing as the glaciers mailed is the least of the problems in the alps. the region faces much bigger threats. the local outhouse, we're seeing the effects here locally. we're seeing glacier collapses, increasing with warmer temperatures and flooding of glacial lakes clicked us in the

i was placing the latest example the collapse of the lease. my mulatto glacier, in the summer of 2022 expensive protection measures are needed for the villages and the valley, as well as the hiking and climbing route, at least until the unsafe sub soil has stabilized again. on a regional level, it will soon become clear that glaciers are no longer reliable water reservoirs in summer for drinking water, irrigating farms for power generation. the there are attempts to get around the problem with dams. but there's a time limit on this solution. take the power generation, for example, moments on most of my own stuff at the moment in switzerland, melting, snow fills the reservoirs in the summer, and in winter,

the water has come through turbines to produce electricity, the important thing to in. so in the future when we have dry hot summers and so, but we don't have glaciers anymore, it could be that the reservoirs can no longer be adequately failed, can extend that we can no longer produce enough energy during the winter. veal to an awesome being, tony's meal can you can storm policy and rivers like the ryans that are important for the transportation of goods. also depend on glaciers during dr. periods, but we're already seeing phases when rivers become non navigable. the researchers in zurich have calculated just how important glacier water is from large rivers. they should, they provide less, wasn't doing colds, and west here. so then they start water, but they release more water and doing warm and dryers in a year with average precipitation. the rang, your basel carries mostly rainwater and meltwater from snow, plus an insignificant amount of glacier water. just seeing the grass the

during such a year, the glacier provides more meltwater and thereby compensates for the rainfall. and the snow melts. water deficit here in bottles, for example, it means that the ice mouse contributes up to one 5th of the flow. so it's make sure that there is enough flow in the risk. without glaciers, the rain will no longer have reliable water levels. alternative transport methods will need to be developed and finally, the global consequences. rising sea levels. alpine glaciers play only a minor role in this, but all of the worlds of mountain glaciers together account for about 50 percent of the phenomenon. the global sea level has already risen by about 100 millimeters by 2100. it could be one meter devastating for europe's north sea coast. and for many other areas that are all ready up to their necks,

in water for scientists like mathias whose it is clear, we have to prepare for an age with out alpine glaciers. escapes and must move the look. health is a kind of a main issue is water retention, coke, new reservoir, for example. so that we have water during dr periods and it's, it's about power generation, creating rail networks for transport, route savings, and it's about your engagement infrastructure facing issue. and we're facing the big technical and economic challenges in moment on helping the at the moment. can we still have a chance to get it right in and prepare ourselves for the future. take full to get the images like these will soon be part of a historical archive. but with the melting up the glaciers, the alps are losing much more than just very turtle ice. so we may have to say good bye to mountain places. but what about far is

less rain full means dry as swell. that's combined with longer periods of heat as a recipe for wild fires, even in northern germany, and as early as may and june and then and by star shop has come up with a way to detect forest fires early in ancient greek mythology dryads, when mythical creatures who protect you, patrice? perhaps these small, green devices will become the dry ends of the digital age. the benevolent spirits of today's forests. every year, fires, destroying millions of heck tests of forest worldwide. almost 8000000 tons of c o 2 are released in the process around 20 percent of global compound emissions. it's an ecological disaster with devastating consequences. it's hard to ask for me,

you've got 20 a teams the 1st time that was visible coverage on t v. and in the media of a major fires in the amazon and australia and we had fridays for future taking to the streets and my daughter to to and that was the initial trigger for me, where i thought i have to do something about this along that impulse let the gym and entrepreneur to get that with the team of scientists software and i teach specialists to develop an early warning system for detecting forest highest the senses deployed in the state of random bug that sci fi as they smell them, like a network of high tech noses, agricultural scientist using the experimented with hydrogen to typed his during his tenure at the tune and institute for forest ecosystems. now he's putting the new census through the paces in a test forest. 3 meters above the ground and pointed towards the south. the hun

sized senses a pilot by the sun and require very little light unnecessary feature for the forest such a dog cousin. this one with the help of capacitive. the senses also work at nights and in the rain. but what exactly does the little green device smell in the coming? if utah, the air contains a number of different compounds, there's carbon dioxide, carbon monoxide, nitrogen oxides, cell fates, and noble gases gauze. this sensor measures all of them as soon as oxygen starts to be removed from the air, the gas mixture changes, and that's the fraternities as causing this. once the senses detect that change, they send a warning signal with precise colors and it via the newly developed cloud platform . it will takes less than 5 minutes. extensive photo note a good. ideally, a forest would be equipped with

a network of senses. 100 meters aponce. the information is post onto the cloud virus specially created in connective things network. that cost and blink show to affectionately calls the internet of trees. in wasn't going to telecommunication companies don't usually have cell towers in the world's largest viruses. that means you can't lose a system that relies on the internet to where on the we need an independent communication infrastructure, because it has to be solar powered and it has to work over a large area. that's exactly what we came up with using this mesh get away yet. so i'm gonna need allows us to communicate over a roughly to kilometer radius at a time. but so step by step that we can move deeper into the forest or to 9 get current early warning. systems rely primarily on visual data, like the cameras on this fire prevention talent needed. the town of eva, spider, and brenda bug allowed more than a 100 cameras, like the scan,

the forests. the images arrive at the control center in real time, where they are monitored and evaluated around the truck. vendors keep good and state in height, it needs a olga when there's a fire fuse are produced and through the lack of wind in the forest, they rise relatively quickly. only up the top of the tree canopy do they start squarely bytes. and so as soon as they're visible in the tree canopy or above it, we can also see them on how busy ols. if a column of smoke is detected, a 2nd camera classic cross direction findings and human expertise help locate the flat. but the compact, small nose can do the same job foster, even without personnel, these level and d, quality in the lights and the colleagues in the control center weren't able to detect the smoke. yeah, but i let the center know when i'm conducting your tests and they ask them afterwards. did you see the fire in? no, that means that the smoking only be detected by the optical systems. when it's above

the treetops, you know, ruba encoding is to ensure the sense and they'll send the detect spy as a lead, but can also tell what he's burning. it's a software is constantly trained. as the scientists have some pulse of forest soils substrates from all around the world. today, for the 1st time doctor, you're going to let is putting pine needles from spain into the tube at the old site tree level red tree way down to the gram. like all of the samples, they all hated to $320.00 degrees. when will sparks ignite? and when will this sense to detect the burning spanish pine needles? they react differently than german pine needles. the german pine needles are a bit longer and they start to smolder more quickly. the spanish ones are more

compact, a little shorter, so they take longer to smolder. that was new for us and some noise. but what's interesting, of course, is when the sensor react. when it smells these spanish pine needles, keep all the experiments of recorded evaluated and repeated hundreds of times need that and come there was such as we showed the sense that can identify smoldering spanish pine in a forest fire. it's an important goal, not only for ultra early fund detection, knowing the precise odor, classification of the binding material can help and quickly selecting the right extinguishing agent. these intelligent senses may now be martin de forest protect us. the trees play a key role in climate protection. that's why there are so many reforestation projects around the world our woody frame as we move about 6 percent of global c o

2 emissions from the atmosphere each year. and as well as the assignment tree planting projects can bring direct benefits to local people teams as one project here, i could do more. okay. so this is the is the and yeah again these women seen the tree is a treasure as they show us how our gun nuts are harvested again. the notes are gathered from the ground. the tree is too dense and tony for picking their song comes from the heart because the oregon tree is their livelihood. and that the who go to the bottom. so you know, different keys all say. and with this, we women can build houses, buy clothes for our children, and send them to school and we work here in the fresh at the ogden tree is all life luck. and you said you were studying the fuck emma. and some 50 other women are

part of a cooperative that was founded in funded by the german development agency. the g i see in the beginning it wasn't clear, it would succeed. our country is, can only grow here in south western morocco. and just a few decades ago, they were almost extinct. to call you book a time, people believe that intensive agriculture was more important to grow fruits and vegetables, fax mode, textbook special. it will see some people forgot the value of the country. suppose all sick. yes. as a result they began to disappear. not getting people neglected them, but they were also depleted by the very dry climate. but it got to move husband easy panic on this. ok. my to refer station began at the end of the 19 ninety's would support from the un ends, germany today, some 2500000 hectares of trees are under protection. they are valuable not only for

the women but also for the environment and climate. the forest service sanctuary for plants, birds, and insects. this okay, we'll see sucrose and know but the secret is also that the tree has a strong deep root system. you know, this spot is sharpie, and so water doesn't lea counts deep in the soil. so we just cannot moisturize retained the new to when he would have seen it. so this is stabilizes the soil against erosion, virginia by the holes, and also helps make the trees so bountiful, left activity. so it's also what makes the oregon far as a powerful defense against on going to certification like other trees. they also absorb the greenhouse gas c o. 2. this type of climate and environmental protection works because it involves local people for those in the cooperative here in the village of drugs and you're good, dear, it is a thriving business. give be, is me. i think her, these are often mindful of, you know,

i had nothing that's the moment i'm going to the island to region right here up to like, and i now have a stable income become paid for my son's education and support my parents. i need the out of their harvest the women produce are gone. well. the pope of the fruit is removed using a traditional technique. the husks are broken open and the criminals removed only then 2 machines come into play to grind the colonel's. they are then cold pressed until the precious oil is obtained. many swear by its benefits on the skin, a slightly different variance has also become popular worldwide as cooking oil. more then the, the yes, a successful model keep different and it can be implemented elsewhere in also regions across the world. so it was of the regional product level. beautiful thing,

you know, because specificity, the women of drug are one to be united city, oregon tree forever. at least that's what they seen during the heart of the good of the got so from tamara today, dw science program. so you next time. and until then, state curious, by the

blessing or a curse mozambique scare swells was supposed to be the economy. but the country is beset by terrorism. instead, western energy and investors have put their big plans on, hey, rwandan soldiers have been sent in a c. c for 30

minutes on d, w a pulse the beginning of a story that takes us along for the ride. it's about the perspectives culture information. this is the, the news w. mine's our interest, the global economy. our portfolio dw business be here's a closer look out the project to analyze the flight for market dominance

with dw business beyond. evelyn charmaya, welcome to my pod cast. lots of matters that i invite celebrities, influenza and experts to talk about all playing loved data and yet today, nothing less the south. all these things in more and the new season of the fuck. com. make sure to tune in wherever you get your thoughts costs, enjoying the conversation because you know it's last matter the, [000:00:00;00]

the the, this is dw news live from berlin. brush as president gives the wagner mercenaries a choice, joined the russian army or leave the country in response to an important march march on moscow. vladimir put in, says wagner. fighters can either join russia's conventional military or go to bell or roost where their leader has reported. they agreed to go plus this time of year
