we're bringing an environmental conservation to weiss 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 highest memories. that's the name of the international project mortgage because sky is working on the chemist take samples from glaciers all over the world stored within the ancient ice for thousands of years of climate data. our research team wants to know, how does climate change work, and what traces does it leave in the ice? that and much more coming up on dw science show. welcome to tomorrow. today

the is minus 20 degrees celsius outside that mortgage macowski has no problem with the cold. she's fascinated by inch an ice. such ice only exists and a few places on us. but temperature is always below freezing the powder regions and particularly high altitude places in the mountains. samples from such mountain glaciers is stored here in the lapse cold chamber. this ice is several 1000 years old. installation ice contains lots of the bubbles and that's why it's a fantastic archive because we can directly analyze the arrows, the palm. it's the only archive on us can do that. i'd love to add them in collaboration with the international research group. the ice member re chikavsky

wants to collect samples from high mountain glaciers on old inhabited continents. her goal is to research the climate of mountain regions thousands of years ago, and to use the data to improve regional climate, full costs. you know, i was able to dots and also i, we have very good data from ice cores and i'm talk to cause about any effects to send directly to india likes and tennessee of course, climate change is global worldwide as in fact, but we want more precise information to the regions where people live for different going well because that's why you have to take measures to protect people from climate change and by spending dimensions for shits. and for them came of i'm guessing to the engine ice is always an adventure icon. bolivia is a non e mountain in 2017. the target glacial life is now 2 to 6400 meters. 3 such as drill down to the rocky bedrock. not the very books in the ice is 18000 years old. only in the po to regions is the ice old. the ice is

made up of layers that correspond to use in seasons. when to produces lighter ice than summer. between the chemical analysis can determine the exact age. if the ice melts, vital data will be lost forever. the closest problem if that's the biggest problem now of course is climate change itself. it's an unbelievable force because of it, we're having increasing difficulty finding places that distill suitable for this kind of reset, as well as i fossil or reset to objects, is dwindling away in the in 2018, just the kosky was with the ice memory team on below 4500 meters, the highest mountain inside the area. on the glacier between the 2 peaks, she and her team spend almost 3 weeks in the freezing cold. they were able to drill down to the bedrock, a 160 meters. deep is now a cool sample from the glacial lies in front of her in the cold chain. but normally

the research is what they weigh into the depth civic leisha bit by bit from top to bottom. but here the most important question was how old is the i sample on the edge dropped within it? let's see for curious of cool of to the ice of items but so then we started studying the lowest layers and we now know it's much older than 10000 years old. now the systematic examination begins the reset. she's wear gloves when handling the ice. so as not to contaminate that piece by piece sunset. blanca and giovanni buckler works a way into the past. first, they saw a real fiancee last funds that plug it wants to nature, examine them to pull in, to find out which ponds grew inside bay area. thousands of years ago, the interior of the ice school will be used to search for hydrogen ions, the types that can determine its age, as well as the climate gases and fine dust. the old

ice from the glacier that lies 7000 kilometers east of the alps has now push it into the iron chromatograph. the chemist use it to determine the levels of that pollution in the past as this on the so here's the precious glacial. i just now we still discount so that we can do it kind of cool analysis on it. and then looking for gases that have been preserved for thousands of years. greenhouse gases like c o 2 and me thing, but also particulate matter that cruise the climate from the kind of corruptions and forest bias for example. but the traces of nitrate search, sol, sage labs, and other elements in the ice also reveal human activities. some of which are not yet documented for loss, cuz i looked at it once with a what's really interesting and that surprised us is that the developments and you're a commercial actually looks very similar. and then we didn't expect the because in europe they introduced pollution control measures in the seventy's and eighty's,

but enough in russia, month of august on done. then we learned the even before the collapse of the soviet union, the economy was stuck in a thing. always even in a recession and as a result they no longer find his money, fossil fuels, and so it mr. glass sofa dioxide for seen a bunch stuff up on pet or bench biking to him. that was also a surprise for us because the data one to accessible instead. and of course one published by the soviet union, but not to the corporate yet. what of what the, the ice caused proof that, that really was a decline even before the collapse of the soviet union. and also as adults had mentioned for the collapse, that's all they don't, i'm up to copy the i samples from the alps contain even most surprises, for example, that the ancient romans were already policing the. yeah. with toxic let from mining . it was not until the full of the roman empire, the became senior again, the more active the economy, the jesse of the, at something that's still true today or otherwise employers,

let's say also the interest rate is that we can also see these concentrations going down again on donald guns, todd so that we can clearly show that the air pollution control measures that we've introduced to also to stop for a sty back and ask rain, have had an impact of it. we can take action if we want to. we can improve things at the best time to come, then you've set t on montero is a 4500 meters high. it's one of the last calculations in the out. the scientists hurry to recover as many i samples as possible, the full meltwater contaminates and smoke edge because sky. notice from previous expeditions that the ice varies ancient. she's determined to recover it and succeeds has, has the team planned to store some of the high schools and, and talk to cap and creation all kinds of ancient glacial ice.

which such an archive fee cease and then towards the guys satellite images shows that and arctic sea ice has been breaking up. unusually early. a recent study shows how it's caused the deaths of thousands of emperor or penguin checks as the off spring. don't have the time to develop water proof feathers. projects are either drowning freezing or starving to death. human made climate change as the cause and penguins weren't the only species suffering. as we see in germany, a cold living trout that lives in oxygen rich streams and rivers. a toad for the yellow valley that needs puddles to survive. on the fat that likes to may, its eggs and other bags nests. just 3 of many species, native to germany, whose existence is threatened by climate change, the author and the issues that were needed here,

but are unable to tolerate the new conditions will become very rare or even die out or migrate students. some german studies say about a 3rd of species will be negatively impacted, negative 5, low said. another species, among them is the brown trout, profess cool condition. somewhere between 7 and 19 degrees celsius ellipse and foss, flemming, unclear streams and rivers. in the future of ritual to temperatures are expected to rise significantly, especially in how some of those things may become critical to the ground troops. to hold the temperature of 25 degrees celsius, the adult fish can just about survive. what's above that they die. the reason is the oxygen levels go down and we'll move to the trans touch. we need more oxygen at high temperatures because that metabolism is working harder and then. busy we'll

need also the moment when the water temperatures get too high and we'll try to move to cooler water. it will migrate up hill and at some point a force their habits have won't exist anymore. it's home for by the streams they need simply won't be available, and that would be the end of the brown trout in central europe. there's a host for the buffalo. what determines whether the climate change hits a species with full force that we're full foxes? it's an animal species, as location sensitive. i'm not very many miles. if it's sensitive to temperature changes, if it needs a particular and continuous habitats and can only be found by or if it's already in danger and the population has already shrunk. the more points that apply to a species, the harder is hit in the german state of has a 130 endangered species to protect it, to die out as a result, climate change the yellow by lead,

tired as one of them. it's normally found in wetlands and southern and central germany, many of which have already been destroyed by humans. the yellow belly type need small puddles and palms to lay at school. both extremely through events like droughts and heat waves are becoming more frequent in germany. and soc could spell the end of the species the old citizens at the table for the or for them to be ins or a group of animals that depend on what conditions are small ponds and water holes. and these run the risk of drawing out during hot spells are drowned by your sites. we're already experiencing this to a great extent. in places in the state of brandenburg, for example, about 80 percent of all amphibians have already disappeared. because the spawning waters are simply no longer there, and you can move on to the nature conservation and ga, not be estimates that there are about $600.00, although yellow belly type,

it's less than the job and stay to pass that makes the $0.05 me. so long, tired when is the rarest? i'm 50 and it's highly endangered throughout gemini just likes the yellow ballet tired. the crew also has a climate related of the spring problem in the spring, every tons from its wintering grounds in southern africa and mates, the females and liaison, and the last of another bad unless the climate change is upsetting. the pads with on the, on the, on the for shield as clearly we had a shift of almost a month in the onset of spring on central europe. which means that many bird species start breeding our, like our coast short and their migratory routes to return earlier. so we may even benefit by making several broods per year. is of, i'm, you know, working for you all. the cuckoo, however, is a long distance migrant that winter's south of the equator. it can reduce its migration revenue because then it would end up in the mediterranean or in this a heart was all along because of the earlier on such of spring along with the

destruction of the habitats of the highest pads. cookie populations have declined in england, for example, it's numbers have dropped by 60 percent, and the last to yes to many animal species, global warming means heat, drought, and a change of that habitat. if the average global temperature rises by one degree vegetation site and shift about 200 kilometers towards the polls, or about 200 meters of puts in altitude, for instance in the out. some species that depends on certain conditions cannot keep up and are in danger of becoming extinct. the same applies to species. the already live at the polls or very high altitudes. the ground tramped is unable to escape. if a stream dries up, who becomes to whom?

estimates suggests 90 percent of its suitable habits. austin, germany could be lost by the end of this century. on so many nights of species and ecosystems climate stress due to heat some drought is already a reality today. the devastating wildfires hit again this summer and especially badly in canada and greece increasingly often the blazes seem to spiral out of control just not just due to dried out forest floors, but also fair in tree tops. research teams can tell from tree canopies how endangered the trees are weather in tropical rain forests, where europe's commercial timber lands climate change has arrived in germany and its forest. but how exactly can you recognize this impact? it's a question biologist about in a z, as in his students. so working on answering the types of research,

tyler at the university of kaiser's lawson, for example. they're investigating how climate change shows up in the treetops. this interior in regular 170 year old oak forest here and we're interested in the plant organisms and micro organisms. sunset can grow in the canopy of the tree, often boy and bucks the work takes them to the very top of the research. tell us that he's 6 meters above ground. once that assign just to measure the house and the activity of the most is in like in, so they've of fixed yet the more human it is, the how fia, and more active they are. on the more active they are, the more of the greenhouse gas c o 2, they can absorb the well being of the most isn't like in salt pet is representative of the house and so far as the eco system, the inputs in order for these organisms are interested in these organisms because

they are very sensitive, very sensitive to changes in climate, so not to allow this allows us to detect con medic changes very, very early loans. and so you could also call it an early warning system button system, which means this saturday, warning system made up as most as in like, kens, indicates that the dry and hot some is the respecting the quantity of the habitats as well as already causing serious problems. for the x rays growing here, they become more susceptible to diseases and parasites and then the archery at the university of kaiser slauson kind of vs and his students are investigating another aspect of climate change and the forest to the focus is on which insects count the live on the trees. it matters because most insects a hub as well as and feed on assessment tree species. and if it's the she's when she disappeared used to climate change,

the consequences would be far reaching the i'm sure i need to understand what else when some vice can out what we found in some simulations that is important to us. species such as beach are missing to tie, set up to 30 or 40 percent of the insect species are lost. so that is definitely an indication that the change can be very dramatic. the abundance at homeowners time, such as scenario would not only impact insects and trees species on dashed a level in 16 pressing at the point where plant eating insects the leaves. the 1st transfer of plants into the food chain takes place logic of your book on from flatten some in the novel condition. all the other organisms of deforest, including humans, depend heavily on an inch because without food welds and without this transfer of materials here. so keep this, there is no longer a functioning eco assessed,

all kind of pull, so no production of food because it's cetera. to prevent this, we must pass to protect by diversity and ensure that forest management is economically sensitive. been months of bicycle fits instead of the suspicion, the po, for example, you find that there are certain trees issues that are particularly susceptible to climate change and couldn't. and then you could prioritize replacing the history as in the forest talking 5 foot ways you can, or you could just protect these 2 species in particular through certain forestry measures to from districts into is pushing defaults. all the protective methods include fostering next stage and mixed species for us with drought resistant trees . species oh, trees should be masked as long as possible as they promote 5 diversity. a wide range of trees, species is also important mode. i've asked to makes insight comp, networks less to set to species extinction.

trees are great absorbers of climate damage in carbon dioxide. but the world's pete lands are even more efficient and sucking up to c o. 2, than all its forests put together. untouched or restored pete lands make an important contribution to climate and species protection. and they can also protect against the flooding. this example is from the southern german state of the various landscape fuller full to the nickel time of felt. a pulse of one of the largest pete lens and stuff in germany. the area used to look like this, covered with ditches and the water level, so fairly low. it a huge pace extraction area. how are you raised some back? i still remember the time back when he was still a little boy. when we moved into childhood, if you look down there,

the whole area was black and done when the wind blew with never clouds of dust and everything was dark and black looked like scored stars as we flip it on the i do. so get some way more than 200 years ago, pete was caught by hunter to heat living rooms towards the end of the 19th century, it began to be extracted on an industrial scale. fastest fuel then from the 1950s, mainly for posting soil. those practices ended in 2005 and now the water is collected instead of drained something that helps the climate, wildlife and humans. landscape ecologist canadian has been working with people and since the 1980s she knows the home for the interventions come the repairs. and the pete lens can then provide even more. she and her husband examine the quality of the pizza oil hair and that goes in those most intox. p ends can retain enormous

amounts of water and of that for one of nature's most efficient tools against flooding. it is 12 most each pete, most of the species holds $26.00 times its own way from rain. from this i can give you and says, i need a flock of an ox like a giant sponge. and you can, i'm it said we've managed to secure massive flood protection for nikolai restoration started in 3005. and since then, we haven't had any more flooding, application votes whose nature is of a section of pete lenses. we not true lies that the beginning of this year. the drainage that just for the form of pete cutting were filled in about 30 pete dams. now prevent water from flowing out. yeah, yeah, it's not for one and then on to media that will be few of the berry bushes that still dominate here for you various dimensions. only 2 months old. so it's very

newton switched to see that look much more challenging in the long run, and after a few years you wouldn't see anything anymore. you'll have to look for it then it's done. so hopefully peyton's make a major contribution to climate protection because drain payments are not totally unable to store water. oxygen also gets to the peak that causes mineralization which releases climate damage and gases like c o 2. and in some cases, even nitrous oxide, which is even more harmful 6 percent of greenhouse gas emissions and the battery i come from drain to pete lens includes a piece of motor every year. our little bit of heat land can store and the carbon dioxide produced 518000 cars. it's almost about 1100 hector as have been re naturalized. and once they're covered and piedmont has again, we'll have a real carbon saying here we're going to fax that over 220000 tech tons of people and in bavaria are alone. and just 5 percent of f as in time is still

a lot of potential to protect the climate and prevent flooding. let us read why and know over to you. do you have a science question? send it to us as a video, text or voice mail. if we answer it on the air, we'll give you a little surprise. is it? thank you. this week's question comes from roughly on nunez from finland. the why do live or is there any occur at the expos, and what makes them so colorful? the risk and take different phones, whether they come dropped behaving cuttings in the sky, old right elongated bands. that depends how turbulent things are in the atmosphere and magnetic field. the,

the auroras to northern and southern lights created by the interaction of electrically charged particles from the sun with the smoking ethics field. so deposit goes hit the magnetic field at 500 to 800 kilometers per 2nd. this directs the particles around the us many and all that the polls. it's only that the soul of the policy cools can hit the layers of the atmosphere. the actions get charged electrically and to match night the hallways and mostly seen near the magnetic poles of the us that are specially common in alaska, finland, and new way know about the colors green,

nitrous produced by oxygen. athens that's now situated around a 100 kilometers. red light is generated by oxygen and even high and a is that the atmosphere design is auroras' come from nitrogen essence. the 3rd deposit goes, have to be very fast to make them play foss. amazing lights can also be seen from space and asked by the way, it's not the only planet that has a boris. the space kind of scapes after spectacled on g to, to choose on the largest punish, and also to assist in aurora is shining. ultra violet, an x ray lights which are rise cannot see the or the humble even detected, ultra violet tours on substance they shine particularly vitally at satins north pole. shortly before midnight on it on
