1:30 pm
the sometimes a seed is all you need to allows big ideas to grow. we're bringing an environmental conservation to life 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 wind wild fires 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,
1:31 pm
shrinking places under the desk 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 a 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 full some time measuring 350000 square kilometers. the world's largest carl reef is almost the size of germany. on
1:32 pm
the it's a unesco world heritage site, a treasure without equal and one we're in danger of losing the las trail years. great. barrier reef the us 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 my happens the system however, i don't think that that causes me to lose. i still get to go out and see the grades are very healthy and be useful. and this so much diversity that the west protecting the countless change simulate the living conditions and the reef. carls are
1:33 pm
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. tearing, leaching is the phenomenon that they fear most because they've suffered too often in recent years. if the water gets to water, the cold shits 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? unfortunately yes, yes, they are suggesting that we're manipulating the environmental conditions and as
1:34 pm
a response to those conditions often most like and these conditions have a name. climate change most strictly 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 soc no, 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 be for some instructions to open their eyes and say government so open their eyes at the true cost of not acting on climate change knew where is that more apparent then that's a great barrier reef for mass of carl bleaching. so 7 years have caused such
1:35 pm
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. and whether there is any coral bleaching base and 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, i think shows
1:36 pm
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 this regularly recurring climate phenomena and cause huge hurricanes in the pacific. how do storms move across the globe? that's this week's question from rodrigo mankato in ecuador trenton, tropical psych close across the a quite bringing to wrench will rain and battering wins. tropical psych loans can inflict enormous damage. they usually leave a vast trail of devastation in that way. the stones and mold in hundreds of kilometers in diameter and compound a single area for long periods of time. that's why people feed them tropical
1:37 pm
psych loans, full of knowledge bodies of water around the a quite 10. 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 korean. this force along the equate to this force is very small. that creates a strength around 600 kilometers wide that sped from the destructive storms. the, the courier and this force causes st claims north of the equate to, to spin in a, come to clockwise direction. well south of the equate tips. they rotate in the
1:38 pm
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 came came within a 150 kilometers at the equate to close to them as a before the but recent decades have shown that tropical site close. i'm moving further and further away from the equates at towards the us polls the 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 the end up is called tap. because the korea, this force works in the opposite direction on the other side of the a, quite the
1:39 pm
read. why do you have a science question? send it to us as a video, text or voice spaces. if we answer the shows, we'll send you a little surprise as the thank you. come on, just on the now to the mountains. according to one recent study, nearly all of our planets, mountain places will have melted by the end of this century. drinking voice, it will be scarce. nope, just me. of the mountains themselves and sea levels rise in zurich, switzerland, a team of scientists is researching mass of ice loss in the else the glacier is and the outlet are disappearing without immediate time in action.
1:40 pm
nearly all of them will have melted by the end of a century. zurich, basically, she ologist mathias whose only a little hope left to disclose and ship is sailed, at least for the small and medium sized glaciers. for the bigger ones, it's still not too late, but at durrett 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 then um, you know, below call outhouse, we're seeing the effects here locally. we're seeing glacier collapses,
1:41 pm
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,
1:42 pm
snow fills the reservoirs in the summer, and in winter, the water has come through turbines to produce electricity to put the, to in. so in the future when we have dry hot summer as well, 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 welfare. so then they store water, but they released more water and doing warm and dryers in a year with average precipitation. the ryan, your basel carries mostly rainwater and meltwater from snow,
1:43 pm
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 bottles, for example, it means that the ice mouse contributes up to one 5th of the float. 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
1:44 pm
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 engaging infrastructure, the facing issue. we're facing the big technical and economic challenges in moment on having the, at the moment. can we still have a chance to get it right in and prepare ourselves for the future full till the image is 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,
1:45 pm
but what about far is less rain full means dry as 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 vice stop 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 yes, 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
1:46 pm
ask for me. 2018 was the 1st time there was visible coverage on t v and in the media of 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, jo miller 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
1:47 pm
senses a powered by the sun and require very little light unnecessary feature for the forest such a dock has and 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 north coming? if you to the air contains a number of different compounds. there's carbon dioxide, carbon monoxide, nitrogen oxides, cell fates, and noble gases gauze. the 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 coordinates via the newly developed to cloud platform . it will takes less than 5 minutes defensive. it's also not that good. ideally,
1:48 pm
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 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. 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,
1:49 pm
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 wanted to and evaluate it 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 how deep cleaning 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
1:50 pm
afterwards. did you see the fire? you know, that means that the smoke can 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 tend to tech supply 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 all of the samples they all hated to $320.00 degrees. when will sparks ignite and when will the sense that detect the burning spanish pine needles? they react differently than german pine needles. the german pine needles are
1:51 pm
a bit longer and they start to smolder more quickly. the spanish ones are more compact, a little shorter, so they take longer this molder. that was new for us and some noise. but what's interesting, of course, is when the sensor react, when it smells the spanish pine needles default, the experiments are recorded evaluated and repeated hundreds of times. and the then come there were 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 out for at least 5 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
1:52 pm
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 to 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 them. so you know, the funky is 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,
1:53 pm
at the ogden tree is all life luck. and you said you were studying the fucking law 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. our country is, can only grow here in south western 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, sex mode, bedroom. it will see some people forgot the value of the country. suppose all sick . yes. as a result, they've begun to disappear, not getting 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, some 2500000 hectares of trees are under protection. they are valuable not only for
1:54 pm
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 sharpie, and so water doesn't lea counts deep in the soil. so we just can't moisturize retained the new to when he with the hudson is solution 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 me,
1:55 pm
i didn't cut off to my divorce, i had nothing that's the loan. and he, i learned to read and write to you a good day, and i now have a stable income become paid for my sons, 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 a 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, the yes, a successful model keep different and it can be implemented elsewhere in other
1:56 pm
regions across the world. so it was of the regional product level, beautiful thing, you know, because specificity, the women of drugs, i want to be united, oregon tree forever, at least that's what they seen during the heart of the good of the god. so from tomorrow to today dw science program, so you next time and until then state curious, by the
