the origin told me about sugars paralyze between your societies, computers and governments that go crazy for your data. explain how things, technologies work. they can that's how they can also watch it. now, the wind wildfire as meet on favorable winds heavy smoke across the boss. distances like in north america in early june, new york became shrouded in smoke due to forest fires 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 under the desk of carlos. 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 carls. a recent study suggests that 90 percent of carlos b c's will soon disappear. and yet, these complex ecosystems are crucial to our plan is around a 1000000000 people in asia alone and source of food directly from re real 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 re it is almost the size of germany,

the unesco world heritage site, a treasure without equal and one were in deep trouble losing. australia's great barrier reef meals, trillion 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 here. my day to day is facing the rest of the system. however, i don't think that that causes me to lose heart. i still get to go out and see the grades are very healthy and be used for this so much diversity, the west projecting the countless tank simulate the living conditions and the reef

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

unfortunately, yes, yes, they are suggesting that when manipulating the environmental conditions and as a response to those conditions, often most stressful like and these conditions have a name. climate change most truly is feeling its effect on land and sea. they heat the drought last harvest and the apocalyptic images of 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. nowhere 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 reef is an enormous economic asset 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, so uh yeah, it's nice to 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. then 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 eco system to the very end.

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. shopping coast sight close across the equates 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 if kilometer is in diameter and compound

a single area for long periods of time. that's why people feed them tropical st cloud's foam 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 womack 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, this force along the equate to this force is very small. that creates a strength around 600 kilometers wide that sped from the destructive stones. the korean is force cause the site plans north of the equate to, to spin in a counter clockwise direction. well south of the equate to they rotates in the

opposite direction. the since 1979, no tropical site clothing has ever been observed crossing the equates. but that doesn't mean it's impossible. in 2001, a site claim came within a 160 kilometer is a via quite to like said than 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 force 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 thing to come on just on the now to the mountains. according to one recent study, nearly all of our planets, mountain glaciers will have melted by the end of this century, drinking voice, it will be scarce. nope, just near the mountains themselves. the and the levels rise. in zurich, switzerland, a team of scientists, is researching mass of 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 mathias whose there's only a little hope left to be scholars and shippers sailed at least for the small and medium sized glaciers for the bigger ones. it's still not too late at e. t 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 melt 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. glad to sandy, i was placing the latest example the collapse of utilities mama, la took 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 power generation, for example, moments on most as by 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, to put it. 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 what we're doing, called web here, so that they store water, but they release more water and doing warm and dryers, seen 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 that during such a year, the glacier provides more meltwater and thereby compensates for the rain fall and the snow melts. water deficit here in basel 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 region. 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 and water for scientists like mathias hos. it is clear we have to prepare for an age with out alpine glaciers. the escapes and most of them 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 and taking assume 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 image is like these will soon be part of a historical archive. but with the melting of the glaciers, the alps are losing much more than just their return all ice.

so we may have to say goodbye to mountain places. but what about far is less rain full means dry is. so that's combined with longer periods of heat as a recipe for wild fires, even in northern germany, and as early as may and choose 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 to 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 yeah. highest destroying millions of heck tests of forest worldwide. almost $8000000000.00 tons of c o 2 are released in the process around 20 percent of

global comp and 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 there 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 gem and entrepreneur together with the team of scientists software and i t 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, the necessary feature for the forest such a dog cousin. this one with the help of capacity has the senses also work at nights and in the rain. but what exactly does the little green device smell in there you've come and if you try, 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, can be removed from the air, the gas mixture changes, and that's the fraternities that's causing this. once the senses detect that change, they send a warning signal with precise colors and it's 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 passed on to the cloud virus specially created in connective things network. that cost and blink show to affectionate because 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 beg alone more than a 100 cameras. like the scan, the forests, the images arrive at the control center in real time. whether i'm limited and evaluated around the clock. finish cube, good, and stayed 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 second's 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 in the role. i'm equally in the lights and the colleagues and 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? nope, that means that the spoken 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 is burning. it's a software is constantly trained. as the scientists have some poles of forest soils, substrates from all around the world. today for the 1st time dealt to you and the light is putting pine needles from spain into the tube of the old site tree level red tree way down to the ground like the samples they all hated to 320 degrees. when will sparks ignite and when will this sense? so 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 on so 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. if all the experiments are recorded evaluated, and repeated hundreds of times, i knew that in kind there was such as we show that the sense that can identify smoldering spanish pine in a forest fire. it's an important goal, not only for the tra ally, fly 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 locked in 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 that's we move about 6 percent of global c o 2 emissions from the atmosphere each year. and as well as the climate tree planting projects can bring direct benefits to local people, teams as one project. and here i could do more. okay, so this is the, is the and 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 a new so you know, different case will say. and with this, we women come 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're studying the fucking law and some of the 50 other women are part of a cooperative that was found in funded by the german development agency. the g i. c . in the beginning, it wasn't clear, it would succeed. our country is, can only grow here in southwestern morocco and just a few decades ago, they were almost extinct. you look at that 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. so title sick, yes. as a result they began to disappear. not going to. people neglected them, but they will 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,

72500000 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 no but the secretary is also that the tree has a strong deep root system. you know, this spot is shot and so water doesn't lea counts deep in the soil. so we just can't moisture is retained the new me to when you who the hudson is this, the stabilizes the soil against erosion doubles and also helps make the trees so bountiful left us to the dislike. it's also what makes the are gone 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. new aga, dear, it is a thriving business. give be, is me. i get cut off to my divorce. i had nothing that's the loan. 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 assistance out of their harvest the women produce are gone while 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 variant has also become popular worldwide as cooking oil. more then the yeah, yeah, so successful model keep different and it can be implemented elsewhere in other

regions across the world. so it was of the regional product level. beautiful thing, you know, because specificity, the women of drug, i want to be united for the oregon tree forever. at least that's what they seen during the heart of the good of the god. so from tomorrow to today, d, w science program, you next time. and until then state curious by the

a pulse the beginning of a story that takes us along for the ride the,

the culture information. this is the, the news w. mine's a blessing or a curse. mozambique scare swells was supposed to be the economy. but the country is beset by terrorism. instead, western energy investors have put their big plans on, hey, rwandan soldiers had been sending us these papers in 75 minutes on d, w, the on to the s b i. c,

i a and most of him for 20 years. the son of a k, a. com is considered the most dangerous i am we fund way we sort of as we say that the poster child for the, the proliferation problem assigned. and then it is said no one has ever seen as phones in the side of the secret fugitive right now. absolutely nothing is right here. the where it is who is covering the wanted starts june 29th on dw. the of

the, this is dw news life from bell in russia's vladimir booth and wraps up the image of national stability following an attempt to revolt. it presides over a minute silence, full ross and military pilot, skilled during the box. it was new to me and tells troops at the privilege that they to fax of stopped civil.
