the nature of a single class place away. 7 months before russia attack ukraine, a field team, documents, daily life, the town. how are the people who are dealing with the growing tension? they change their world. we are with, you know, when i me inside start 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 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 on the death of carlos. we still have time to prepare the hello and welcome to tomorrow. today, d, w sign show the kind of crisis is having a devastating effect on corals. a recent study suggests that 90 percent of carlos bases will soon disappear. and yet, these complex ecosystems are crucial to our plan is around to 1000000000 people in asia alone suits the 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 for some time measuring 350000 square kilometers. the world's largest carl reef is almost the size of germany, the of the unit

school world. heritage site, a treasure without equal and one we were in deep trouble losing australia's great barrier reef. the australian institute of marine science board games, these 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 healthy and beautiful and there's so much diversity that the west protecting the countless chang 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 groups residents? to re terry bleaching is the phenomenon that they fear most because they've suffered too often in recent years. if the water gets to the car real shirts, algae, these algae are not only responsible for the car, was brilliant colors. they also provide the coral with nutrition. if the allergy disappear, the car will die. can visa effects be directly traced back to us humans? unfortunately yes, yes, they are suggesting that we're manipulating the environmental conditions and as

a response to those conditions, often most stressful 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 the burning forest. at the same time, cities, villages entire landscapes are completely under water. extreme events have become normal. environmental activist crystal faulk 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 say, 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 for massive 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 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 was that there is any carl bleaching base and the entire data to the marine biologist 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 own nino is looming again? in 2019, just regularly recurring climate phenomena in close, huge hurricane in the pacific. how do storms move across the globe? that's this week's question from rodrigo, mankato in ecuador. 10 shopping coast sight close across the equates bringing torrential, rain and battering wins. tropical psych loans can inflict a numerous damage. they usually leave a vast trail of devastation in their wake. some stones that move in 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, most of it can invest the rates 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 forces, 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 macareola's force cause the site plans north of the equate to spin in a counter clockwise direction. well south of the equate to they rotate in the

opposite direction the since 1979, no tropical site. clayton has ever been observed crossing the equates. 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 clones. i'm moving further and further away from the a quite sensible would see us holes the we can only guess what might happen if a slight clone which across the equates that it would most likely lose its angular momentum and end up as the 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 message. if we answer the shows, we'll send you a little surprised as a thank you. the 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 glaciers in the alps are disappearing without immediate time in action. nearly all of them

will have melted by the end of the century. zurich basically, she ologist mathias whose there's only a little hope left to disclose and ship of sales, at least for the small and medium sized glaciers. for the bigger ones, it's still not too late, but at e t h direct 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, 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

dallas place and the latest example, the collapse of utilities mama allowed to make sure 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 dens. but there's a time limit on this solution. take the power generation, for example, moment on most is by owns, but at the moment in switzerland, melting, snow fills the reservoirs in the summer. and in winter,

the water is pumped 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 to extend that we can no longer produce enough energy during the winter veal to an awesome beam. tony's meal can. you can store policy on 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 watts of doing colds and width here. so then they start water, but they release more water and doing warm and dryers in a year with average precipitation. the ryan, your basel carries mostly rainwater and meltwater from snow, plus an insignificant amount of glacier water. i was just seeing the grass that

during such a year, the glacier provides more meltwater and thereby compensates for the rainfall. and the snow melts. water deficit. here in basel for example, it means that the ice most 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 to the global sea level has already risen by about $100.00 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 whose it is clear, we have to prepare for an age without 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 about power generation, creating rail networks for transport, routes of homes. and it's about your engaging infrastructure facing issue and we're facing the big technical and economic challenges in moment on the home the, at the moment. can we still have a chance to get it right in and prepare ourselves for the future full. so the images 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 good bye to mountain places,

but what about far is less rain full means dry as soil that's combined with longer periods of heat is the rest of the for wild fires, even in northern germany, and as early as may and choose at the end and vice stop shop has come up with a way to detect forest fires. early in ancient greek mythology dryads swim mystical creatures to protect you. the trees, 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 eh, 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. 2018

was the 1st time that was visible coverage on tv 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 to 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 forrest highest the census deployed in the state of brendon bug that sci fi, as they smell them, like a network of high tech noses. agricultural scientist, you experimented with hydrogen detectives 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 are

powered by the sun and require very little light and necessary feature for the forest such a dock has. and this one with the help of capacitive sensors also work at night 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 that's causing this. once the senses detect that change, they send a warning signal with precise coordinates via the newly developed to cloud platform . it will takes less than 5 minutes defensive. it's also note that good. ideally,

a forest would be equipped with a network of senses. 100 meters aponce. the information is passed onto 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 virus. and some of 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 mission 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 so that we can move deeper into the forest or to not get current early warning systems were not primarily on visual data, like the cameras on this fire prevention talent needed. the town of eva, spider,

and brandon bug allowed more than a 100 cameras like the scan the forest. the images arrived at the control center in real time where them wanted to under evaluated, around the clock. finish key, good, and stayed and hide. it needs a olga when there's a fire. fumes are produced, and through the lack of wind and the forest, they rise relatively quickly. only up the top of the tree canopy, do they start squarely mice. 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 navarro and d, quality in their lives 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 asked them afterwards. did you see the fire?

you know, that means that the spoken only be detected by the optical systems. when it's above the treetops, we 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 pulls of forest soils, substrates from food around the world. today for the 1st time dealt to you are going to let is putting pine needles from spain into the tube. the old site tree level red tree way down to the ground, 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. 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, keep all the experiments of recorded evaluated and repeated hundreds of times. need that and come 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 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 that's 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 team as one project here, i could do more. okay. so this is the is the and yeah 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 they have gotten tree is their livelihood. the who go to a new so you know, different is all 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 the study is fatima and some 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 in our country, is can only grow here in southwestern morocco and just a few decades ago they were almost extinct. so you look at that time, people believe that intensive agriculture was more important to grow fruits and vegetables, sex mode professional. it will see some people forgot the value of the country. suppose all sick. yes. as a result, they began to disappear. lag on the people neglected them. they will also depleted by the very dry climate, but it got to move husband easy follicle. this okay, my to re, for station began at the end of the 19 ninety's would support from the un ends, germany today, some 2500000 headquarters 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 shop based and so water doesn't. lea counts deep in the soil or discounts moisture is retained the new to move with the hudson is so this is stabilizes the soil against erosion, virginia by the holes, and also helps make the trees so bountiful left to the dislike. it's also what makes the oregon far as a powerful defense against ongoing 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 me. i did cut off to my divorce. i had nothing that's

the loan. and the islands to read and write here. absolutely. and i now have a stable income become paid for my sons, education and support my parents. i need the victim 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 kernels removed only then 2 machines come into play. to grind the kernels they are then cold pressed until a 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 successful model keep to me and it can be implemented elsewhere in other regions across the world. so it was of the regional product walkable,

the whole thing, you know, because this is just the think the women of drugs i want to be united, our country forever, at least that's what they seeing during the heart of the good of the got so from tamara today, d, w, science program. so you next time, and until then state curious, by the

can you hear me names? are we are all set. i'm, we're watching closely. we all seem to ring of the story behind the news. we all about unbiased information, feel free mind,

so do to mention done sometimes a seat is all you need to allow big ideas to grow or bring an environmental conservation to wife with learning facts like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can make a difference. knowledge grows through sharing, download it now for the

old. we can be the generation, the ends that feel good. malaria must die. so millions can live the

this is the, the new live from ballot. lot of it puts it and makes his 1st appearance since this weekend's a bolts of revolts box in this video address, the russian president fails to mention the most serious challenge so far to his long route. also coming up.
