so we might see similar themes then was that you've reached the end of our show. i have reached the end of my shift. thank you so much for being with us today from all of us here in our news. remember lane, if it's the latest headlines you're looking for, or is of course, always our website that is b w dot com. thank you so much for being with us today. by the why do humming does not get drunk. why do go to tasteful waves, squeeze all bodies. how much do we need to put a stop hans praying for help find beyond says get smaller on dw science, outtake talk channel. the

finland is home to tens of thousands of woodlands proportional to land mass. the country has more wetlands than any other on the planet. there is the marietta tons rise here in the woodlands. rich, natural beauty draws many visits the but the wetlands aren't more so important from climate. the, in numerous amounts of compound a store to us. some is locked in palm, a frost, the will depend for us to mount massive amounts of comp and would likely be released in to the atmosphere. it's celebrating climate change,

but it's not too late. the recent studies suggest that while these goals and wetlands may pose trends fail or so, right, we don't put you in to take the, how much human kind work with the wetlands to come global climate change. the research group from the university of helsinki has arrived in killer busy all of

a lapland in the fall, know the thing, and that hoping to discover whether the palm of frosty is already melting multi effects that could have blown up be chime, or say, probably better exciting who, who, who, oh, really. so on this is from one and a half. feet is the focus. just ice. yeah. textbook. yes, we can use it for long drinks. no thought. i'm not when it feels like that i, my task is to get the dog complete until you get all this long. some project is concentrated on time, approximately not. so what we want to find out what process is this? that's all for that now. okay, let's see, and the 1st contains huge amounts of mercury, another talks, and this one is very useful kind of compounds and gas estate, that costs are we on

a need that we want to know what could be released and what effect that would have on climate change while do i mean the next some components can cover stuff, but we have to assume that it moves to the next on the right to it till it does say that what about those are the best that and to stay in and the northern permafrost may contain hazards that are as yet unknown to us. the in the summer of 2016 alarming news came from the yamaha peninsula in north western side bay area. a young man had died of anne's rooms. the disease that had been eradicated from the regions 75 years sonia of a 2000 reindeer died from the disease. an additional 5 adults and 2 children were infected

. the answer on it was suspected to have sprained from a contaminated reindeer congress, which of lane frozen in the palm of frost, but decades. subsequent studies revealed that an exceptionally warm summer had melted large sections of permafrost. the soul that apparently revived the answer, i expect to hear him which 1st infected animals, then the reindeer herders. the seams 2016. no new and strange outbreaks have been detected in yamma. the mounting of the palm of frost times, however, tools damage to buildings. it also releases

carbon dioxide and me thing both known ex underwriters of climate change the, the arctic circle surrounds the noise power to the ground. here contains twice the amount of carbon that is found in the atmosphere in march. if it is stored in the arctic wetlands permafrost, the compound a blessing and the cost with outage that would be known as i phone us. at the same time, it's the cause of global warming. to greenhouse gases contain compound carbon dioxide. and me, st. is these 2 gases to contribute the most,

most ferric, wyoming in nature comp, and is in constant association. the wetlands in northern europe play a key role in the comp and cycle yes. uh huh. okay, so my thoughts can you hold on not a document that he later thought that i think we, we want to understand how com and select network and the science guides, i guess they all take is the most i that's kind of a for or something. what else? there was some wetlands on the launch wetlands, so you'd be any while away they are, we want to start the older interactions you might have with that kind of get technical fund just to call them to tell you when it moves from one place to another. so now hold is a to the, wherever the comp and store have those here and what sort of sources you got the,

how does it end up in the atlas van or more in the ocean the last day that we spent about $3.00 to $5.00 ultimately. so don't really on wetlands planting pastors. no, not here in the north, it's sort of, it's also in the tropics, the vice, or for ricky like to go, us call them by when you have to go to effect. so climate, the small company stored in wetlands then in the entire opponents vegetation, up to the oceans. wetlands of the us launch is comp and reservoirs so i thought he left the car as eco systems, wetlands absorb carbon from the atmosphere. sylvia, after the ice age, it was continuously drawn from the air force base. if there weren't any wetlands, the atmosphere would today be much richer and carbon. and with every wetland that's destroyed on a, from

a turban gets released into the atmosphere across the spa. little study has been made of wetland permafrost, so the possible effect of permafrost, mount a launch, the unknown data must be 9, focuses all of us. i'm assuming there's hardly any data from northern regents like this one was in a gas measurements like these have only been undertaken in a very few places around the world to say less. all of our research thus far has been largely based on assumptions on the federal still up. it's got the last to exceed one hypothesis. as the time it warms the ground becomes walter locked. you'll still, you get all the full off. that's them, it's nothing is the permafrost inside these mountains, now it becomes a puddle like this one here. these release a lot of methane, which is the potent greenhouse gas into the atmosphere. that's one possible scenario that we wind up with these expensive,

what area is all about leaking methane into the atmosphere? is that, was it the if on the state of the e, shoot me an e and permafrost in siberia has apparently been going to mount some of the agent phones and silas fine for the 1st time in 10000 years and its effects post traumatic stress for global warming signs at the time of frosts melting have been observable for some 20 years. now the images are assigned to areas collapsing, permafrost mountains stoked fee is as early as $20.00. 14 scientists concluded that the mounds were filled with me signed, which was being released from the melting permafrost. the pressure inside them had grown so great that it best opened the mountains and

made on a crop, said, i didn't know if i had them. tell us why all these me think trying to sign a mile or a bit like st. cost, which can be found around the well, i think the box in the permafrost platform honest plugs the mine effect layer of frozen soil kid or when that mel line. and it's a bit like pulling the stopper out of the sink. and 1st thing from the top, rushes out and just leaving a crate to the hunt, biolife the bottom of it, more of done at the cool b. as almost started as i have confirmed the melting at this time period, permafrost over the years initial assumptions become increasingly concrete. by going 60, not them right down in the past it, oil, anything, emissions can be locally quite high times and that can increase. but the effect is apparently not terribly significant. a of them now pull up, all the americans are signing of the left toys to fix stylish stuff like this. not

just let me see. yeah. nice. nice. now a macro fossil. what have you found? the seed. it looks like bulk bean, how does it look in the middle menu? n t savanna. right, so i thought thoughts i, i'd also say it's many into a book being seen to sho get. that means that it used to be very damped here. soft ground, not much undergrowth on the bottom of the seed, the scientists have just found it's several 1000 years old. it indicates that the landscape around this bulk must have once looked a very different and the most painful stuff thought of him. and then the last good that we drilled was mineral matter, not bogs, settlement at all that source. i didn't see that some, oh, there used to be some kind of a lake or a puddle, then which was later filled, and then formed boggs. this is the way nature works is they will understand, nothing is forever see, i like this environment, look very different after the last, i say about a goodness about fix permafrost,

bogs, a long time capsules. they help us study environmental and climate changes over hundreds of thousands of years. in a sol, how year by year sheet accumulates in the swamp courses in southern finland, the peat layer can be several meters, the side lobby, some. and in lapland, we only have 2 meters of a feat, does assessment. the layers are a kind of time machine or dried them that record the whole history of the wetland. myself, scientists touch through the lines of stratification for signs of temperature and humidity changes to like a half of the sale of mazda. so, you know, it's easy to see in the terrain. this is something happened and honestly, there. and often the changes appear as differences in color to see. and then when we bring the samples to the lab, we can see in more detail how the vegetation has changed across history, documented over the course of 10000 years old. there have been at least

a couple of changes to the vegetation, which tells us about changes in the environment. that's the mainland. it's normally like a mere. we have a sample of about 50 centimeters from a blog and lapland. luckily, we can clearly see changes in the composition of the pizza. this layer is perhaps a 1000 years old. down here we have us our grasp agitation which grows in human conditions. at the same time with us will have to say from us here, we see a clear change in the 18th century, and nobody has it. all of a sudden at that point, during the little ice age called home, or for us, begin developing in fennel's condo. so on the surface of the bog, dried out or changing the vegetation completely, shrubs begin to spread out during that period. the 6th and yellow here on the far left, the vegetation has changed once again. this layer reflects the situation at the extraction point, the conditions we still have today,

lucas moss is growing there. an indication that the environment has become more humid again, p a mom or stomach 6. by observing the various layers, it is possible to make a rough, initial prediction of changes. i had the same document that i also thought except by the phone with us. if that's the alignment, we can see how the layers in the bog behaved at various times say look at it in general, say the carbon dioxide, along with warmer temperatures, promote the growth of p and, and the accumulation of carbon. but these forecasts do not take into account other aspects related to wetlands for now. so expensive changes and vegetation bucket of things like res talk or the top of myers bod grove fires to nice that are considered in these models. not with on the bottom. as the following an example of much more research is needed for that one of them on that the.

ready the finland is a great place to study the wetlands effects on the climates after a wetlands compress the finland. an area of the size of point you call the

functions from several ways being important to the things they've provided food for humans and animals as well as fuel. the heating finish focus on is filled with tails of spirits, elves and dantes living in the westland. so it's no wonder then let's finish has thousands of ones for different kinds of westland wetlands. well, ones fear, there's unpredictable environments. a space between us and water being and beyond in the past, people were buried in this one night to waste was dumped down the know to box around like that. sometimes stores common,

efficiently. one offers release it. so in a 2nd release i thought any last, so what do you they're all over 100 different types of women and finland alone. get it, that the heat each is different in the way it's accumulates or a mix common. so i'll do that these with the kinds of bugs that release maintained into the atlas van. i made down the drive volt amounts on what accumulates install cove and very efficient. make it to a name, visit the data with data, edit devlin garcia that are still held overhaul, finland's wetlands, hoping, drained the goal, was to try out the wetland soil, making it most suitable for forestry and agriculture. one such wetlands is around scale on copy in southern finland. the dense

spruce forest was originally a woodland bunk. decades ago the wetlands were drained to support tree groves. the ground water table was lowered considerably. is what i'm saying less and less for you to those ought to be let me read on. finally on. we're in a well trained whitland to present which has become common for finland, decala, according to the latest findings. this type of fee tease is a major source of emissions. the sewing, the drain, white gland forest produces greenhouse gases like carbon dioxide and me saying at the same time the far as trees take in carbon dioxide from the yeah, that means a peter and forest subs. there's both a source of emissions and does a common sink drains beat forest and pete fields on the last, a significant source of the world wide emissions date,

but you've still most as much greenhouse gas emissions as deforestation. dance in the asset to comp time to change. the wetlands have been matched as a point of focus. the draining of wetlands reduces bio diversity. lessons, water quality increases the risk of file, the carbon released from wetlands is bad for the climate. human intervention can however, impact just how much compound is released into the atmosphere. one go could be to strengthen the role of wetlands as comp and syncs. extract the file out at dawn and that was one option could be witness restoration in finland, for instance, east the account, this wetlands have been trying to even trying them up, filed in 15 to 30 percent of cases. no forest has been able to grow and met,

so instead of draining the wetlands, it just ruins that positive, natural quantities, only not with restoration. below the westerns can begin to function naturally again to time. so i'd like and one's most thoughts. i'm solving colvin from the atmosphere. stop, boy, you say all gone towing the a c. and so that this is an email here. you don't like it has restoring a wetland means returning it to a state as close as possible to its natural log. the ditches are filled, the water level rises. once the water has return to the correct level, pete begins to form again. compound is removed from the atmosphere, absorbed into the soil. the

period comes and they said, the $75000000.00 most of them, and then we subtract. this was a pretty deep, and that's only now give out in spring, and the dest directly, if it's a dry summer, will be at around 122 minutes of the camera. so, you know, people suffer how you almost certainly ask me, of course, when the water levels so low in around skill and copays, the effects of the various deforestation models on wetlands emissions are being investigated. the aim is to raise the water level in a controlled manner. so that the forest remains viable. as a result, carbon dioxide emissions will also decrease. however, the water level must not rise to high. yeah, so basically what is the hun expand?

the water rose right to the surface of methane would be released the need. the goal is to maintain groundwater at a depths of about 20 to 30 centimeters where it doesn't release methane last se i hope. yeah. and then go sufficient aerobic surface layer can prevent methane emissions limits on the fastest. all the researches measure of the carbon dioxide india, the methane present in the soil, changes in vegetation, the ground water levels, and the circulation of liquids in the trees. they track the liquid flowing through the trees to find out how they react to filing fluctuations in the ground water levels. metal tests at the box onboard. yeah. yeah, i mean, the heal patty. i said we have 2 sensors here in mind. those are in 2 different things for the height of the front sensor shows the degree of, of operation and the word. yeah, the measurements isn't very accurate, but it's better than nothing said of this sensor on the left gives us information

about photo synthesis. so con, have sugar is transported via the flow, him to the places where the tree needs it for growth, the routes on the trunk, concession order storing at all costs. what okay, or so who the tonic with this one as well place to maybe even if it's better what i me on this one. yeah. yeah. so the plates fixed on straight, so yeah. types, good, intrude? well, things in photosynthesis, trees extract the carbon dioxide from the changes in the water table can disrupt the process. no, not so equis. understand that this will methodologies log eco systems. i paint forests or controls by water to a certain extent of it and the greenhouse gas emissions depend largely on the water table take them up as well as on how much carbon dioxide is absorbed by the trees,

such as the ground water level is especially high water trees run into problems with their water intake so lot that they can struggle when it's too let's look at a st. mary's felt also faced the movement and circulation of greenhouse gases attract using automatically operated chambers and measuring devices attached to my stuck on through the load up the box is placed slowly over the ground, then the chambers, he'll go to the law, say that it then measures whether there's a gas source in the ground, and we'll go from that if, if there is a gas level inside the chamber gradually increases on the same at the best that we extract the gases from the box and look for concentration increases. so let me just to say what was a minute gain from that we can calculate the flow speed to see that was through last as an nope out in the last 4

we have a check research team has come to ron's can compete to investigate the impact of deforestation on wetland emissions. so that's why we try to study the same kinds of management though remover off all 3 or removal of selected threes. and how this affects cardboard, cycling, kind of micro ps in the soil. we have the sites in the right. there's columbia in your, my name's slow by now and feeling this very well for thing, because we need some, a set think which will glance and with a specific mega station represent thought, the 4 large box of the morales for us. so if we just look at the threes around our, a very small and decide that the house of them are taken and how you know them are less, i think for all, for us, if we can. but the, to harvest slightly less than because the other harvest thing in that is that these

are add ons, up the 1st time. so maybe just around our side, we go a little bit more, 3, yes. and went around. you can take as much as you, as you like 90 area and funky the decompose pont and animal material affect the production of carbon dioxide and me thing in the soil. when trees are caught down, it has a detrimental effect on these micro organisms and on greenhouse gas emissions. so we'll get to the microbes. how would a change during the site life cycle over to for us? and whether it's makes more sense to golf, just select the 3 main thing the microbes decides of the

once he's global, warming continues upon the frost mounts. what happens to the calvin stored in a natural state wetlands, up and off the the yes, he said less and he said i have with the ice the trapped here. we're looking at a very special component of this, of this even when that i smell this, well, the water flows off somewhere else that studies, i mean, this carbon might end up in the arctic ocean or in some other body of water out of it. and there are many different possibilities, and they probably don't need that at a loss advice. that's the same fucking. yeah. so it's almost impossible to predict what will really happen, i'm guess, the model for the northern permafrost fox, there are 3 possible scenarios in the 1st the wetlands good even went to and for

a time become sources of me. thing themselves as the ice within the mounts, the, the 2nd possibility is that the wetlands will dry out and release large quantities of carbon dioxide into the atmosphere. the side option is that the bunks could become even more efficient. compounds sinks the bell. i mean even much the production of bio mass and let's see, that's to say plant growth increases in a warm climate and that could accelerate the accumulation of people the cost with allowing plans out of the drive and produce even more plant through photo synthesis that pete and then binds a lot of carbon dioxide from the air, which would have a cooling effect regardless of scenario, regional situations. very cranky,

isla my still in no state. i move on side of medical according to climate full costs inside of the rainfall and the northern latitudes will increase by around 20 percent over the course of a century. this could of course, have a major impact the idea of what the regional defense has a huge dollar. what is it? some regions control house. yeah, yeah. well, i love his mike to come even what the, how this in town affects common levels will be really interesting to see that there was still a lot of research to be done. it doesn't mean in any case on to paint guns are incredibly important in the global calvin cycle globe, obviously the level retreat at the university of helsinki. the soil samples from inside

permafrost, mountains, uh, analyzed our base, the temperature now in storage. so now it's so nice, 0 degrees c. so we saw that you guys 0 degrees is a kind of a low temperature that lots of stuff it may take from the all these organic. so already even so those, it's 0 temperatures zeros. i'm always coming out. yeah. okay, and the laser, we will increase the temperature till 5 degrees c, and then 15 degrees c and the at this higher temperature, you will see that those last lot on ponds will be emulated. and much more that this low temperature, the power to re simulates the melting of permafrost, isaac rooms, it's not just me saying that's released from the thousands of years old pete soil.

volatile organic compounds are set free to some of the interesting things, the simple. so for all this last year, we saw a lot of new things coming out of those. okay. so that would be something that weren't here. okay. and the interesting part is that the piece to us, it looks like the meeting was old. me saying it was not, not a new me saying that's form of it so it's become active again. all right. but it looks as if the, the says nice and was frozen in the soil. how do you know? is it, why did it look like? oh, because interesting, because because it came out very suddenly. so it was like a very sharp pulse, like me thing. volatile organic compounds kind of boom the time it's one way that they do this is by forming small particles and creating a cloud. the general effects on the climate to volatile organic compounds and me

saying being released from time a frost have not yet been fully researched. it's hard to say if they have well, me all for the impact because there is a balance between these 2. so we probably, we will more though these impacts later to know if eventually they have cooling all the hacked our climates and got the most government bottom off on maple hi, i guess on the sunday, no one can predict whether these gases will have a cooling or a warming effect while i meet them up because the process is in the atmosphere telling are so complex specially this is something of a pilot project. they told me that they had on the

trees were cut down at the ranch, can on coffee research site at the beginning of 2021. now in the summer, the aim is to measure the effect as the deforestation here affected local greenhouse gas emissions. one thing that's clear from the outset last compound accumulates in the soil of cleared areas. that's because there are no longer any trees to absolve the common through photo synthesis. so here's i understood that for photo synthesis. got there only very few plants here. neil, meaning that the sink effect diminishes considerably and also at least at the beginning on academic logs are still not vegetation caused me to see what the dilemma how the organic matter is that compose this. so very likely also change because there will be this, usually they can both have a car one and the car one will be less and less digestible for the microbes,

so this is will be x by in other words, off to complete deforestation. the soil binds less comp and then it once did. however, in the partially cleared research area, virtually no changes in greenhouse gas emissions can be observed. fully understanding methane emissions will remain a challenge over the coming years. or methane, the we don't have answers from the last year sampling because the book, the re on that to produce. and also that one is you meant, reside in deeper box or the profile. so now we are adding the deep beats on plank to see where they are, how boom done they are, and what the amount of methane is flowing, vault us. so however, we expect that the, with the threes being stopped, what the table will arise and was rising to the table, the,

my phone organic book 30 out, we'll get closer to the surface so that methane will have a smaller box to escape the research project. and run scanned, copy will continue for several years. only later will it be possible to say with any certainty whether planting new trees does stablish in palm and, and forest are a good way to reduce emissions. and so on the quantities of meat, of what i'm interested in the next 3 to 5 years and will show whether permanent forests can be the solution. here at this location, by empirical evidence gathered here will then show us whether emissions are changing as their models have predicted to capacity in the for me. and while i'm gone on, i of you in the

spring 2021. the research team from the university of helsinki is in for a surprise, a pounds, a piece bound typical of permafrost areas, is best open in the scale, move on to bulk near c. okay. that's cool. that's what i use the state of people. yes, good idea. are we hitting ice? no, interested in here? no ice left at all. yeah, that's already a meter deep, so how's it so as they get all done, see ssl say so see a lot. the bottom lamp and image warming has occurred in the inner permafrost

layers. what am you said? well, if we keep coming to measure it every year, we may yet see and collapse completely. it may be that the pulses life span has reached its end. and it doesn't necessarily have anything to do with global warming . it's complicated because one cracks like this appear, so everything collapses, a new one simply form again based on how long 56 years this, now i want out, that'd be yes. if we measure here again and 5 years time, we'll see completely different things. the most of the reports published in august of 2021 by the intake of a mental panel on climate change provides a cautious assessment of the relationship between pete lens and global warming. according to the report and the frost mounts and emissions from pete lens are

likely to accelerate global warming, the dialysis then valley and then it almost have finally to set up or to decide or be, or if the only pcc report concludes the release of me. thing from the permafrost is a very gradual process and mine, so there were none of them. so for me, fine volumes that we've been hearing about. however, the process is significant and i'm just going to use it contributes to global warming. because when the time the frost mountains may assignments release, the medicaid setup process itself will at least i make the amount 8 am i stuck on it, or that's aligning this on any of my files to on this stuff is that it must, i should perhaps be aware that it can also happen quite quickly on the if the pulses suddenly collapses ice, then a huge amount of methane can be released all at once. you log in, it takes a while for levels to normalize again, but that's whether that's one or 2 percent on the software. however much it is,

it doesn't matter if it definitely means by an increase on the current amount. and as i say about the guy give me that, that is not the 1st thing that happens here will have an impact all over the well facility. and i quote, this isn't a remote corner in that sense and not, not change is happening here. and then also on the effect this region here are the ones that passed on by the evolution car. and so i'm gonna have an impact on the global situation, the long distance,

the human kind as to extend the rated global warming. but it can also slow it down. the soil on the, on the top priority is preservation and these natural westland shouldn't be misused any longer or dining quite the opposite of on it won't conservation programs should be set up to ensure that they remain on touched a month to main infrastructure. so it does not place in wetland areas like the factors that allow us to utilize the potential of nature. it can come by the same climate change down the road on that that will work on both. and the, i've had that to say it almost amount of sense darling's the, the message from science is clear. it's not to liked

the, it is still possible to support and strength from the wetlands, nature's comp and sinks. down the other hand, it's something that has been neglected in the debates which that most of the concept of common things. and when it comes to this topic, we tend to focus on the on forest is that the wetlands are also excellent club and rest of us include common things with the human intervention here. i mean, could turn wetlands into more effective comp and things for the future. calm b a here in the yellow. yeah, that's the level i sort of the

. ready the to many visitors is screening communities and the environment, the c o 2 emissions by cruise ships are a major problem and tourism because without economic loss is made into i mean in 30 minutes on d w. the
