12:30 am
for stomach 6 by observing the various layers, it is possible to make a rough, initial prediction of changes i had said that came in the box. i find that the thought that that fell on i'm a little, i mean we can see how the layers in the bug 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 extensive changes and vegetation bucket of things like res, barcode, and light off of myers ball gross cut, the tires to nice that are considered in these models. but with the following an example of much more research is needed for that one of them at the. ready ready ready
12:31 am
the . ready the. ready 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 fins. they provided food for
12:32 am
humans and animals as well as fuel. the heating finish focus on is filled with tails of spirits, elves and dantes living in the wetlands. so it's no wonder then that finish has thousands of ones for different kinds of westland wetlands. well, once fair, there's some predictable environments. a space between us and want to being and beyond. in the past, people were buried in this one. latent waste was dumped down the know to box around like that. sometimes store common efficiently, one offers release it.
12:33 am
so in a 2nd release i thought any last, so what do you, they're all over $100.00 different types of what not understanding the loan, get it that, that the heat each has different in the way it's accumulates or a mix common. so what do these with the kinds of blogs that release me tight into the atlas van? i made tanya drive up to mountains. the accumulates and store, call them very efficient, make it to a name, visit them, get a data, edit devlin garcia, that are still a hell of a hot finland's wetlands hoping, drained the goal, was to dry out the wetland soil, making it most suitable for forestry and agriculture one such wetlands is around skill on colby in southern finland. the dense spruce forest was originally a woodland bulk. decades ago the wetlands were drained to support tree groves.
12:34 am
the ground water table was low at considerably. that's what i'm saying. i as in love with the ability to and finally on we're in a well trained woodland to present which has become common for us and to call a few. and according to the latest findings, this type of p t's as a major source of emissions. the sewing of a drained 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 serves as both a source of emissions and does a common sink drains, pete forests 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
12:35 am
the asset to cause climate change. the wetlands have been matched as a point of focus. the draining of wetlands reduces bio diversity, wesson's water quality, and 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, the 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 i can stay on the draining the wetlands, which is really that positive, not true quantities. i mean with restoration below the wetlands can begin to
12:36 am
function not turning again to time. it's not like a one's most thoughts. i'm solving colvin from the atmosphere. tom boy, you say all gone. going the see hands or thought to say the man. you don't like it has restoring a wetland means returning it to a state as close as possible to its natural one. 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
12:37 am
period comes and they said the $75000000.00 o and then we subtract. this was a pretty deep and that's only now give out like in spring. and then just to ask we've, if it's a dry summer will be at around 122 minutes. the boss painburne scene of the 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 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. the yes, the vision one is a 100 percent. water rose, right to the surface of methane,
12:38 am
would be released as i need. the goal is to maintain groundwater at a depths of about 20 to 30 centimeters where it doesn't release methane. i say i have the yeah, new ga, sufficient aerobic surface layer can prevent methane emissions on them. it's on the fastest the researchers 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 until fluctuations in the ground water levels. metal tests at the cox on through the end of the heel fatty acid. we have 2 sensors here in mind measuring 2 different things. one height of the fun sensory shows was the degree of, of operation and the word. yeah, the measurement isn't very accurate, but it's better than nothing said this sensor on the left gives us information about photo synthesis. so can have sugar is transported via the flow em to the
12:39 am
places where the tree needs it for growth, the roots and the trunk of your orders, thawing at all possible. what tokyo, so who the tonic with this one is one place to maybe even if it's better what i me on this one. yeah. yes. the plates fixed on straight. so yeah. pipes good, intrude? well, thanks in photo synthesis. trees extract carbon dioxide from the changes in the water table can disrupt the process or no, not. so of course there's them, it's just one methodologies, bug eco systems. i paint forests are controlled 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. it is the ground water level is especially high water trees run into problems with their water intake lot best. they can struggle when it's too wet.
12:40 am
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 god. 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 the gas level inside, the chamber gradually increases on the same at the best of the extract, the gas is from the box and look for concentration increases. so let me just to see what it was a minute gain from that we can calculate the flow speed a that was to loc as an nope out of the last 4. we have a chunk research team has come to ron's can on co pay to investigate the
12:41 am
impact of deforestation on westland admissions. so that's why we try to study the same kinds of management, the removal of all 3 or removal of selected 3. 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 little by now and feeling this money welfare thing because we need some, a set thing with a glance and with a specific vegas ation. or i present the 4 large box of the more l for us. so if we just look at the threes around our body shop 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 slight blue loss and because the other harvest thing is that these are, i don't have 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,
12:42 am
like, materia and funky, the decompose pont and animal material. affect the production of carbon dioxide and me saying 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 the for us? and whether it's makes more sense to golf, just select it's 3 to maintain the microbes, decides the once he's global,
12:43 am
warming continues upon the frost mounts. what happens to the calvin stored in a natural state wetlands, up and off the the yeah, she said, let me say i who is the ice that's trapped here when we're looking at a very special component of this, a visit meant when that i smell this well the water flows off somewhere else that studies and 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. the best and fucking yeah, so it's almost impossible to predict what will really happen, i'm guess, the model, the for the northern permafrost fox, there are 3 possible scenarios in the 1st the wetlands get even, went to and for a time, become sources of me thing themselves as the ice within the mounts
12:44 am
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 bumps could become even more efficient to compensate the bell. i mean even much the production of bio mass and let's see, that's just a plant growth increases in a warm climate and that could accelerate the accumulation of people that got cost with allowing plans out of the drive and produce even more paint through photosynthesis 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 graphically. isla, my still in no state. i move on side of medical according to climate full costs
12:45 am
inside of rainfall in the northern mex tooth will increase by around 20 percent over the course of a century. this could of course have a major impact, but the regional defense has a huge dollar. what is it? some regions control house. yeah. while others might become even with the how this in town affects common levels, will be very interesting to see that there was still a lot of research to be done. it doesn't mean in any case on to patients are incredibly important in the global calvin cycle globe, obviously the piano level retreat at the university of helsinki. the soil samples from inside permafrost, mountains, uh, analyzed our base, the temperature now in service. so now it's
12:46 am
so nice, 0 degrees c. well we saw that you guys 0 degrees is all kind of a low temperature. that lots of stuff it may take from the all this organic. so already even so those, it's 0 temperatures zeros. i'm always coming out. okay, and the later 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 are less low on phone calls will be a mutation much more that the low temperature laboratories simulates the melting of permafrost, the as it rooms, it's not just me saying that's released from the thousands of years old pete solely on volatile organic compounds. a set free to some of the interesting things,
12:47 am
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 it's for him to so it's become active again. all right. but it looks as if the, the said anything was frozen in the soil. do you know, is it, well, 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 because if they
12:48 am
have, will me all fully impact because there is a balance between these 2. so a 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 tending are so complex garcia, this is something of a pilot project. they told me that they had on the trees were cut down at the ranch, can on copy research site at the beginning of 2021. now in the summer,
12:49 am
the aim is to measure the effect of 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 calvin through photo synthesis. so here's, i understood that for photo synthesis because there are only very few plants here. neal, meaning that the sink effect diminishes considerably and then also at least at the beginning on academic logs, are still not a bunch of taishan cost with this. what the dilemma how the organic method is the composed 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 die, just simple for the microbes. so this will be express in other words, off to complete deforestation,
12:50 am
the soil binds less comp and then it once did. however, in the partially kid research area, virtually no changes in greenhouse gas emissions can be observed. fully understanding methane emissions will remain a challenge over the coming years. for methane, the we don't have answers from the last year sampling because the book, the real and that's produces and also the ones you meant for reside in deeper box over the profile. so now we are adding the deep of beats on plank to see where they are, how boom done, they are, and to the amount of methane is flowing, vault us. so however, we expect death to which the 3 is being stopped. the will to the table will arise and was rising to what the table, the, my phone organic buck 30 out, we'll get closer to the surface so that methane will have smaller box to escape the
12:51 am
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, do stablish in palm and in forest, or a good way to reduce emissions. to settle on the quantities of meat, of what i'm going to west. all the next 3 to 5 years and will show whether permanent forests can be the solution. here at this location, empirical evidence gathered here will then show us whether emissions are changing as their models have predicted to capacitance in the problem for me. and my lim calling on why are you in the
12:52 am
spring 2021. the research team from the university of helsinki is in for a surprise. upon set a piedmont, typical of permafrost areas as best open in the scale, move on to bulk near c. okay? because that's i use the stick with 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 as it all done? so, so see a lot of the 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
12:53 am
reached its end, and it doesn't necessarily have anything to do with global warming. it's complicated because when corrects like this appear, so everything collapses, a new one simply form again based on how long 56 years this. now i want that, yes. if we measure here again and 5 years time, we'll see completely different things. silas, the report 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
12:54 am
dialysis then valley and then it almost the finally to set up the side of your if you only pcc report concludes the release of methane from the permafrost is a very gradual process and mine, so there were none of them. so for me, find problems that we've been hearing about. however, the process is significant and understanding. it contributes to global warming. because when the time the frost mountains may assignments release, the medicaid setup process itself let loose out. i make the amount 8 am i stuck on it or that's aligning mcdonny. i'm about to on this stuff. is that in my thought, i should perhaps be aware that it can also happen quite quickly. now, if the pulses suddenly collapses ice, then a huge amount of methane can be released all at once. i'll get it takes a while for levels to normalize again, but that's whether that's one or 2 percent on the stop or however much it is, it doesn't matter if it definitely means by an increase on the current amount and
12:55 am
use that the, the guy give me that the 1st thing that happens here will have an impact all over the well facility and quote, this isn't a remote corner in that sense and that change is happening here. and then the notes on the effect this region here, the month, the postponed by the ever notion car himself and have an impact on the global situation. the long distance, the
12:56 am
human kind accelerated global warming but it can also slow it down. the soil 1800, is the top priority is preservation in these natural westland shouldn't be misused any longer or dining quite the opposite of on it was won't conservation programs should be set top to ensure they remain on touched 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 the one or more both. and the i've had to say it almost amount of sense. sorry, on the, the message from science is clear. it's not too late. the, it is still possible to support and strength from the wetlands,
12:57 am
nature's comp and sinks down. in the other hand, it's something that have been neglected in the debate. so so, so the concept of common things atlanta, when it comes to this topic, we tend to focus on the on forest is that the wetlands are also excellent. copeland rest of us include carbon sinks with the human intervention. here me 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,
