8:30 pm
still lots of applications. i don't even get of florida station 90 because that's what i'm doing that right now. the melting ice caps torrential flooding. well fires. climate change has already had an impact on millions of minds and on nature. like in forest research as a trying to hear what would sound like in owning world. that's a much more on this week show. the thanks for joining us on dw science program. welcome to tomorrow. today marcos meta and his colleagues at ward 1600 meters above sea level and the
8:31 pm
total forest preserve in switzerland, saucy, and todd valley. the woods here haven't been managed for 50 years. the team installed recorders and sensors here last fall to you to code it and then they record sounds in the ground and also from the air and they measure the micro climate at the same time. that's actually the core of my acoustic ecology work. you always really need context for the sounds you record and a landscape and context things. you also measure the local climate, dakota key, and all the devices are concealed by weather proof cover is able to withstand rain, wind, and snow. sometimes things still go wrong. the don't get ahold of something's not on it. probably some miles. then moisture got into it for it to godaddy. com on the ground sensors record sound waves that are then amplified a 100 fold. it sounds like this
8:32 pm
little control disease. what is the soil you hear a wide range of sounds made by the animals that live in it, not just crawling and feeding noises, but also certain acoustic communications between animals. that's actually the most exciting thing and it makes sense. this is natural, it's dark underground and when you can't see each other, it's communicating, acoustically is a good option. measuring bio diversity, acoustically to do so devices don't have to be assigned to specific animals. at this stage, it's mostly about detecting how much diversity soils are home to places where more and different sounds are measured or home to more species. one day the recordings could be used to create sound art, but they also provide research data barcas made or has worked for years with eco physiologist or whole month's 5 foot measures even more parameters among the moisture content in the soil. and also tree grows to do so he developed
8:33 pm
a device called the point 10 durometer. i mean the can in the me co made we can use it to measure when the trunk expands and contracts again with micro meter precision data reveals when and how much a tree grows up is consuming. you might think trees grow between spring and fall, but that's really not the case. growth usually only happens within 2 months and within those 2 months, only on relatively few days and on those days only at night. so growth actually occurs during a very limited number of hours on 12 months to the data. he records helps identify the climate of conditions under which patrice species will still grow. and when drought and heat caused it to stop growing the bottom of the steel. if a tree dies research into it, we'll hit a dead annual max, but we'd like to be able to use the setup to predict where certain trees species
8:34 pm
are reaching their limits and have gotten some stones around 400 trees spread across switzerland has been wired up in this way, all of them are part of a measurement network called tree net system gets the dots and the phone. okay, so let's talk, here's yesterday's data from all over switzerland by it's co lated automatically and maps like this. so you can see how much the trees are growing at any given moment and deployment, or whether they're going better or worse then in other years old slash the box and all the norms on the, on the upper map indicates gross. the lower one water supply avoid united with loss of assaults and all the water supply was actually good this year and gross as in previous years is very below average cost of like you definitely can innovation by compare it to our society at all to an aging society sees more data and it's the
8:35 pm
same and the forest, the more old trees you have, the more trees will die, is the our goal with this particular stretch of woods is to continuously rejuvenated, to encourage a young dynamic forest that can fulfill its protective function. well, who the feeling called the main protective function of this forest is to shield the road below from avalanches rock or mud slides. but of course, it also provides many more benefits bodies to, to design. and for us are good down use because they retain precipitation and to then during dr periods, they release this water again, it goes, the soil stores a lot of it that you know is just about can on managed for us. do what's needed just as well as a managed one just on the outside, just as super food. it could be that it works great for that. could also be that it doesn't work beautiful, and we actually want to manage,
8:36 pm
at least that's human nature and ancient that we want to do something about it and not leave it to chance and house. and it's us, missed into, for the last 4, marcus made or to forest experiments are part of a bigger question. should this cultivated landscape maintained by humans be preserved? or should we allow the wilderness to reclaim it? style by showing the sight i believe we have to move away from a human centered or anthro post send tracking perspective. if we want to solve our problems and dealing with the environment, it leaves the, the acoustic ecologist expects the initial results in around 4 years. indications of whether the wooded mountain eco systems can adapt on their own. or if they will need a helping hand from humans, the trees in far is having to
8:37 pm
adjust to moment temperatures. but also many of the plants we credit for food. oh, sometimes drink in germany for instance, it's changing traditional wines to growing seasons, leading to ones with punchy of flavors and a higher alcohol common sense. the lights are dry of white wines of the past have growing harder to make because higher temperatures now cause grapes to ripen more quickly and produce more sugar among them those made with the reasoning variety, his thoughts that come from the countries, ryan go region originally. now research is at the university, they're looking at an innovative way to provide grades with a little shade the grades being harvested here or not just any grades. they're part of a pilot project for a very special reasoning vintage at a vineyard attached to guys in hon. university in the high and gal region of western germany, scientists are trying to find out how the fruit develops in the shade of
8:38 pm
a 3 meter high. i agree voltage system also called an angry p v array. in addition to the shaded trial area, grapes and a control field or ripening under normal conditions, increasingly warm somers have accelerated the process. you know, if we have the laser as we have earlier harvests. so in the last couple of decades, the grapes have on average, ripened around $30.00 to $40.00 days faster than before the, the 2 of them are going to have the warmer temperatures also change the aroma of the varieties grown here, the young about. and if so, the research involves nothing less than the future of wine, or at least of reasoning lines. and not just here in the volume gal, regions, climate impact research, or county or come on has observed more frequent, extreme weather. july 2023, for example, was the hottest since measurements began in 1885 that's actually happening here. so i know weather wise, we had a few challenges. first we had
8:39 pm
a very dry phase from mid may to mid june. then there was a short thunderstorm given and after that it was really hot and dry again for a long time and kind of here. so there with these gaps and precipitation slots and everything highlighted and read the temperatures. they're all significantly higher than the long term average on. yeah, and again, this is claudia, come on, thing. so many people underestimate how severe climate change could be in the future. extreme weather events like heavy rain and hail followed by heat waves and droughts will occur more often, eventually and improve rid of point. but we really noticed this heating up and has to contend with extreme consequences with stuff that's never happened before. situations that are new. for example, we've never seen sunburn on the fines before and done in the even. the semi trans spirit photo voltaic modules are designed to protect the vines from too much sun and prevent early ripening. well they work month which started hope so. ivana to
8:40 pm
each one on tongue. of course it was clear to me from the outset that the micro climate in particular would be altered by the protected conditions. the specifically that it would be cooler under the photovoltaic system during the day. but then at night, the temperature would be slightly higher due to solar radiation light who at the time in other words, that the semi transparent modules would naturally change both the light qualities, tend intensity with intensity. and then what some of the difference is caused by the altered climatic conditions. under the modules surprised the scientists. in the 1st year, you see a gas to observe that the vines produced more leak surface area. this is, i can use that again. so trying to connect to, and this is actually a completely natural reaction on the part of the plan. so there's less light is available, they respond by increasing the amount of area used for light absorption. so they
8:41 pm
produce larger liter. another observation was that the modules altered the distribution of water in the vineyard during and after a rainfall, apparently in favor of the thirsty vines. as the lessons of the fun it's, we saw the oyster in the system last. it's much longer as of a photo voltage modules above the vines, keep them mostly drawn. then up between the modules where there's a gap, it rains in that system. and after that water hits the ground, it remains there longer ride on the lift, just as i was born on the head successful. it's been a few days if not weeks since the last rain and in the control area, everything is dried out again. and let's hear, the soil is still moist and for the kids the project is successful. could agricultural landscapes one day disappear beneath high tech structures covered by photo voltaic or res, instead of plastic sheeting, like in southern europe, concierge finished yet in that gig,
8:42 pm
we'll see this. there were islands of solar cells here in this area, not covering everything but islands. where of hikers know they can shelter from the scorching sun. okay. then that would be something i would find very attractive as a tourist. if i knew i could always find a patch of shade and an island of biodiversity and not the one where i could charge my cellphone or my bike battery. and that would also be an option of the cool flood via the ultimate move, which could find growth yielded important findings for the scientists. but now they're also curious to see what delayed ripening under the modules means for the taste and sugar content of the freshly pressed juice, or must more sunshine currently drives the sugar content of the grapes here so high that the resulting wine contains a lot of alcohol the system could bring back, traditionally dry, low alcohol, reason things, thank you again. what is the fermentation is just coming to an end. so it still has a lot of intense enrollments. fiedler intensive at the home. yeah. so yeah,
8:43 pm
which is that's less difficult. what we're trying to do with this system is to turn reasoning back into the wine. it used to be called our hypothesis is that if we achieve a delay in ripe in there, and then we'll achieve a profile, perhaps more similar to the reasoning we use to know back in the old days, kaden on us defy those debit come photo voltage, x and fit a culture, an opportunity to create one that's fit for the future. and that harks back to the past of the world famous german riesling, which could otherwise some day disappear, due to climate change. with that about fines technology. that's like dw science is now on take time. what's to be fun? why do gravitational ways?
8:44 pm
when did people begin getting high and laughing gas out the drums boogie to the beads. and what's the pass that the kids football find the on says gets most c w science. oh, new tick, tock, channel. the climate change isn't only having an impact on plans. carlos, for instance, of badly affected as well. most recent files of years old. but now environmental degradation and climate change a threatening to destroy them. within the next few decades, warming waters have hit carlos hauled. now blue clements reese play a vital role in the help of many of the species that destruction has not calling effects for marine predators. and pray alike these tides, this eco systems also provide a key feed source for millions of people worldwide. is the still time to save them
8:45 pm
. coal rates, unlike any way else on us home to mind blowing, bio diversity in the world. recession with red dots. here are they covered less than one percent of the ocean floor, but they actually support over a quarter of all marine life built training animals control products cult oh, a great deal of that magic. i'm that beautiful color to a complex co operation between organisms. i'll be live in the products tissue and provide nutrients to the call in exchange for protection. but this kind of cut team, what is on the rent from climate change. c o 2 emissions dissolved in the seas, making what is more acidic and weakening coal skeletons. and that's not sol, as global temperatures, so cold re suffer through as
8:46 pm
a more frequent and intense ocean. the heat waves extreme temperatures caused the audi to produce home full chemicals. comforting the coal polyps to kick them out. this is cole, bleaching wave vibrant products 10 white from heat stress, a process that can eventually prove fatal. and global warming is already driving fast bleaching events. today, in the eastern caribbean, the goal was to find a balance protecting culls and other eco systems while still enabling tourism and fishing, fake sample in specific areas. the funds that the community was so involved in the designation the design of these areas. that is why it was so successful that are also plenty of ways to enhance conservation methods like these take pain underwood to silence to look back fish for one slightly surprising example. and that is
8:47 pm
evidence that by protecting reese from local stresses, marine protected areas, build resilience in the face of ocean, a certification and rising temperatures. so we have to have multiple strategies in it as inter marine protected areas. face is lizzie mccloud, whose global cultural rates lead at the nature conservancy, such as like lizzie, going one step further in the quest to help rates resist climate change by investigating how to actually toughen couple rates up. and so some of the strategies people are using is, are taking corals that are, we call it stress hardens. so they're better able to deal with ocean warming and actually transplanting a moving down from those areas to other areas with the hopes that they'll pass along that traits and they're all spring and help the coils in that new area of be better able to cope with warming, one way of doing this is to find naturally heap assistant colors that have survived
8:48 pm
told what is the full transplant them from one base to another. and these are the only cutting edge techniques, such as using other teams, hoping to not just tossing up cold rates as a whole, but also the individual calls themselves in my research, mostly focusing on increasing the tolerance of karl. so he's, this is ecological geneticists, madeline find open matter lines, looking at a range of approaches to make colors more resistant to rising temperatures, for example, selectively breeding, to toughen out the toilet animals. or alternatively, tinkering with the out the a give call them back colors to mark for all get a live inside the carl dishes, we can take them out of the coral. and most of these can be cultures in the lap. and in the left we can increase the rate by which the cell gate equals madeline. use this approach to create heat resistant,
8:49 pm
i'll get which when put back in products, created more heat resistant. carlos. so if we combine all these approaches, is that it will we be able to save these unique eco systems from climate change. if we implemented every tool in our toolbox today from marine protected areas, reducing pollution using some of these more active interventions, stress hardening or manipulating the genetics of corals. it will not be enough to save corey's if we do not reduce emissions that is absolutely central. the truth is that coal respond incredibly sensitive to wyoming voters in 2018 the into governmental panel on climate change. one. but even if the well, the limits global warming until 1.5 degrees, cold res could declined by 90 percent. if temperature is increased by 2 degrees, that figure is 99 percent or higher. but the well talk by more than even
8:50 pm
face given emissions passed. if we don't fight to stop climate change, the fight to save cold reef is doomed. not in the distant future, but within just a few decades. couple of weeks could be the fast ecosystem entirely lost to the climate crisis. environmental decisions around the world. whether that's reducing plastic use or limiting global warming, could make all the difference for the future of the world's race. even though they remain family anchored to the sea bed, co, reese play an existential role in the development and reproduction of many migrate to re animals. have you heard about a new report from the un convention that attracts the most vulnerable migrate to re species on land c, an s? it provides a so brain picture of that current plight of
8:51 pm
a one and finally the close to extinction. the list of species and the threat includes wall chemicals and various the titles and also a very special migrate to re shock. this week few a question. it comes from real heavier g, l, and mexico. the, the whale shocks migrate the notice the gentle joints of the sea, the largest fish on the planet, the they like seville and populate tropical and sub tropical voters. but we get to see them very rarely. while shock speed on plankton that's built to fetus, they stuck in some 6000 liters of water in our field throughout the food and expelled the accessibility with beckon's, they migrate and set to food and congregate. that particular hotspots. one of the
8:52 pm
best known as the main gallery reef of west and australia. the whale shocks migrate to every spring. when the car rolls on, an foss quantities of eggs, and carl spun, attract the crew and plank, 10 the molten full 100. while shots come together on your lead for this method should be the natural spectacle summit truck smoke. lesson dice is the langley reef office. one of the best opportunities to get up close to these giant creatures which grow up to 18 meters long. maybe while shocks are so relaxed because they have the cities scan in the animal kingdom like a fingerprint. each whale shock has a unique pattern of spots and stripes the
8:53 pm
to help identify the animals. a database was created with photos taken by divers and tourists called the wiles books while shocks the fighters around the lies by specially to sign software. originally developed for the hubble telescope, adopted for the new pompous stalls in the night sky, and the markings on a whale shocked form similar patents. the data shows that the number of whale shocks coming to langley his credit note for the yes, i'm to l 6. 3. come has several times satellite transmit is low research has to track individual whale sharks, migration rates. and they offer new insights into the behavior of the still relatively mysterious giant fish. they migrate much further than we long thought. the current record is held by this female while shock, software from panama across the pacific ocean,
8:54 pm
the 235 days, there was no sign of the human. she'd been sitting the way in the ocean depths before she finally returned to the surface. after a migration, more than 20000 kilometers the why? if you have a special science question, send it to us as a video, text or voice mail. if we on the street on the show, we'll send you a little present as a thank you. come on just task that so for now. thank you for watching tomorrow today and do join us again next week for another edition of
