set you up today, so i'll have more than some of the hour of next on dw documentary, serious today looking at this trend agreements. dwindling. glasses have good. the can you see is what old car tires have to do with the production? here's a hands on the real media watch now on youtube. the

greenland ice sheet top is a secret giving us a look into while future the the pump to that secret runs through these rivers of mount water, which form every summer and disappear every winter. the

of the day drain into holes called moody on this one, these believe to continue hundreds of meters down into the ice. and that's where on going the south. you can hear the water. it's lowered, right? so that's what's fun about it. the, the ice is melting, sea levels are rising, we will know event, but no one knows just how fast it is happening. even though that may be the most dudgeon question to answer right now, the,

i want to go down that home together with some scientists to learn about the future . yes, but you will quickly become part of the past. if you're not careful, the looks of them be okay. following, i don't really have much experience with climbing on ice as a filmmaker, i know more about cameras, white balance, and depth of field as a child. i had a place where i could be all by myself, a world of my own, the bulk behind a home where i lived a when every day. oh yeah. on expeditions deep into unknown territory. and then one

day they started building town houses that i was outraged when they started cutting down trees. they continued building, even though i took the key to the trailer and threw it in the lake to sabotage they walk my well disappeared. maybe that's also what's happening now. only now it's not just my little, well that's punishing the coordinator to the port.

the number is 8.8 meters. now this looks like a beautiful little price. jason box door today and jensen and alan hubbert. i'll be joining these 3 extraordinary professors and to explore as on their expeditions, documenting what they find by the way it season. is it safe to walk just uh, just uh yeah it is. you got to think about their weight and other what the next one is. you see the silver it's here it's, it's not sick. nope. and you stand on that you're just gonna fall in and you can easily 50 meters, although no, no, no, no. somebody puts us. no bridge. what,

what you were standing on that wasn't say, you know, the, these, these take lives. the most scientists study the ice mount from un office using data from satellites radar and computer models. but there's a lot we cannot do time in that way. don't to jason and dial and believe it's necessary to study the process through to rank jumps of ation and field status. they call it ground truth full for 2 are soon contract is the fact the employees the neutral 20 years ago. you could go directly onto the ice from here. now you have to won't quite fall to reach it or no, my god please. when you will,

can i see will to climb its history. the dog i say for that that slice from the ice age, which is more than 11000 years old. i'm gonna keep her own top. is eliza color dice, younger than 11000 years from the intake glacial periods. welcome or the east for for many reasons. but then you can stand with one, like in the, i say jesus, i'm with the other, like in the integration period like this i'm standing here is a very dramatic moment in climate history. or this is just one instrument of many. here we've been studying this place here over a decade now. so we have a pretty good idea about how this play see it behaves. i think it's important to come here and make the measurements and just not sit behind

the desk and download your data rocks on the satellite the any real way to know what's going on a device you should use to access it. you've got to drill holes. you're going to put sensors there and then you have to go down there and find that the, the the a warm a wild also means a more humid wild with more precipitation. how will

this affect the ice? how does most snow and rain affect the mounting process? it show to have a huge impact on the future climate. but we don't have much data on it. the one of the few scientists who study the relationship between increased rain and snowfall is professor jason box. well this is getting really big the way that we can check the fly is this idea of pouring water over pouring water? oh yeah. well the flood the parchment. yeah. not too much water, but we want to check if uh, if this repair job has worked slow and he is like rain

stuff through from the top or yeah, the top does come through so far, so good. can you get your spray bottle just where my hand is from the outside. jason, who's been on i have a 30 expeditions researching the climb edge on the ice sheet. there's a come into. well, there's some that's coming through dammit. this is professor conrad steph. and jason's mental early in his career, a pioneer in climate research. jason was one of the office of the you and climate change report that was awarded the nobel peace prize in 2007. we really don't know a lot about just how much rain falls, how much snow is there. rain can damage the snow. it can accelerate the melt

process. and the so you see right now this is bare ice back here. it's dark, it absorbs a lot of sunlight. if you have a 6 know cover, and we think that climate warming is bringing more snow. so that actually has a protective effect on the ice. but at the same time, there's more rain. so we have to also record how much rain is fall. i need to make sense about the competition between these 2 forms of h 2. 0 it's. it's kind of an untold story. i think it'll become a hot topic for other scientists. during the winter, precipitation falls as snow layer upon land settling as a thick cover on top of the ice, essentially protects the ice from the heat of the sun, the

the, the time of my 1st expedition. the objective is to see how much snow is falling during winter. this place is devoid of life the we will be staying here for 12 days. moving towards the coast on skis in slants along the way. we'll stop many times a day to drill into the ice. accompanying

us is jason's friend and research connie massaging the wall. now. i've marked in my book these 2 areas that are risky. so there's one kilometer which crosses where we go over this rich. as i clearly remember the crevasses jason had shown me, they don't visible now the in order to find out how big the cover of snow is, the scientist must drill through the snow until they strike ice. the

we had to dig this little bit because we got more snow here that we were expected. we, we didn't bring enough drill equipment to go that just extra read or $330.00 . it's a total that yeah. the they need to do numerous snow drilling as a day to obtain a reliable scientific result. do we get agreement between the 2 course? not a good 30 minutes. ok, let's take one more. pretty impressive cantavon collective knowledge about the

state of the ice sheet. stems from data gathered using a primitive drill, a plastic bag and the kitchen scale. we set up camp here, sleeping 100 kilometers out on the ice sheet on top of a mattress of frozen water, one kilometer think. the, the gcs would be to use his show for yeah, definitely people to make good japanese down there. yeah. i hope good. mm hm. the

it shouldn't be this warm here. today. it's like summer conditions in the middle of april. think about all of this landscape absorbing all this extra heat, hard not to feel that something really is happening here. it's like a kind of like

a disaster in slow motion. it's i call it the burden of awareness. it's the opposite of ignorance is bliss. when you become aware of what's happening with climate change, you don't sleep good at night. whoa . if you stay here long enough, something interesting stops to happen. you begin to see the nuances. you notice that the ice rate actually sloan so bad, that it isn't one giant find plant to that it actually pillows up and down.

you can see that the wind has shaped the surface of the ice like waves, frozen in time. it looks like a photograph of an ocean, an ocean that might soon be back in motion. the frozen still gas in here. so i'm just warming up the

. we have to take this route to avoid these really bad crew basses. then here, here, there jason, and a massage these measurements will be compared to measurements counted by a nasa airplane in the hands on research is meant to amend these laser measurements . it's, it's a very small piece of, of, of the puzzle. but i think that image that's forming is coherent. i've been working on that image for 2 decades now and it's, it's a, it's an image of a changing environment. the

i do everything that i can to inform, the climate change issue. and that's for the sake of my daughter and all the other kids in nature that surrounds the jason's gps unit indicates one of his weather station sharpie. right here, right here somewhere. the baby over here. the

the, this is what this thing is. 3 meters fall. standing on the ice. i just now need to dig down meter and a half or so to get the memory card the, you know what? they should be able to dig fast. it's either speed metal or of those to somehow but you know, gives you the power to fix. know not if you really want to measure a small change is happening on the ice. you must do your observations at the same hour every day,

all year round. this measuring station measures the level of snow every 4 hours. if it's working properly, it won't get jason highly accurate snowfall data. it's a new technology. measures neutrons reading down on the planet from space and the that the snowing between that block. some of the neutrons expensive information here. i don't yet know if this equipment is working. it's really important because the models and the satellite measurements, they cannot capture this kind of thin layer of snow. to understand how quickly the green that i see, there's no thing we have to do this. oh,

let's see many files here. that's good. and the dates are starting when i remember this is 30th of august. last year. when we started this is it stopped measuring on new years, it didn't record continuously. but these files are larger because if it's uh, it did measure continuously. it's just recording the data in verse. so yeah, i think it's working. that's great. pretty heavy. yeah. yeah, i'm really happy i put so much effort in to this work and

you know it a lot of times it feels like it's just pure effort in your you're wasting your time but seems to be working so basically feel kind of emotional after all that, all that preparation for this, this trip, tears of joy or not. with all of that information, we can learn a lot about a process, ease of melt, how much damage that can do to the snow in the ice a. we didn't know that before the, the thing about ice is you have to listen and, and it will reveal its secrets. and the way that we listen is with these recording

devices. and then it tells us the story, the some high clouds to see that maybe that's the weather the we've been told about the hello, is this the met to office? hi um. yeah, uh po the nice to know gala gift. uh,

this is uh e denmark. uh and uh, we are on the inland ice request uh, weather prognosis of the 10 meters per 2nd in the morning and 18 meters per 2nd in the afternoon for 3 days. it's better for us right now when the wind is only light and much lighter to build a wall to take the force of the wind. cause 18 meters per 2nd is i think a little bit more than these 10 are really made for. that's why we make the wall, so we'll be okay. so the

go down, because this layer so difficult, so far, the icon help, let's think about what would happen if i'm 10. so ripped apart, relying here in the middle of the ice sheets is nothing. but how sleeping bags? okay,

25 knots in the morning and gusty, the a little bit stronger. building to about 40 knots. i have no idea how strong 40 not since i'm given a situation. i'm not about to ask the the

do you want more coffee? looks like we're getting through. all you can really do is sit inside 10 the off to 2 days. the storm suddenly stops the zip. someone flicked the switch. jason, a massage, she can finish that final snowed rollings and i noticed that we can see walter for the 1st time to the end of greenland ice sheet.

we made it to the final destination, the safely made it safely. oh, it's my family saying that they miss me. it's my 7 year old. i love you dad. what are you do a type of fly? i am waiting for helicopter, the jason's measurement show there's increased snowfall here. we can see that there is a gradual increase in snowfall like 20 percent more snow fall since $1840.00. the snow helps protect the ice, but at the same time this increased rain phone to which destroys the protective layer of snow. the rain is winning the competition. jason talked about

so far, all scientific calculations on how fast the ice is mounting and how quick the sea levels will rise. that's not accounted for this effect of increased snow and rain for the the more c o 2 emissions reductions. now we have it, it buys us time, delaying the time that hundreds of coastal cities to come flooded because the ice seats are melting, irreversibly we're buying time and saving lives. the for the last 5 years, jason has been planting

a forest in greenland. he wants to offset the c o 2 footprint, so if he's research on the ice, well, the mature tree will have a 100 p lowes of carpet in it, which is about half of the bio mass is carbon. so in this a heck there, there's going to be 100 tons of hard to the is going to change the pricing in the wind. read a little bit about our personal company footprints and what we do. you know, i think most people are very eager to just to give a hand to do something. we have to do a lot of small steps in on directions. yeah

. you know, this is something that we can do to take yeah, i mean, we're not gonna drop down all of our carbon, but this is something that we can do. and we all need to start doing something and not just talking about it. it seems like it fits well. hopefully i hope to come again. see if it has grown into a big tree ice and ice coal research have taken up professor delta dental jensen's entire research life. oh, as jason puts it toward the seas, very much about science with a capital s big science. for the last 20 years, daughter has been leading one of the world's most ambitious scientific projects far

out on the ice. together with a group of 50 danish and international scientists, she is drilling about 2500 meters down into the ice to gain an understanding of what happens inside the ice as well. 8. so now you'll see that you can see the ice coincide. and now they're going to pull out the in a call with the b, we have more than 80 tons of ice and 20 kilometers device close here to provide some insight booking through a history book. i can tell you a story about every books we started to tell them that cass, this is the,

the, the don't to is one of the scientists to know the most about won't be ice, can tell us about climate history. the findings to this is that to the ice from the ice age come, it's 11900 years old. each 9 represents the in the spring of each year. the soaring store no spring dust with them, and small app bubbles foam around these dust lakes. some things they look a bit like champagne bubble in the middle east when the snow falls to the ground and is called between snowflakes. as low as snow falls last upon desire of snow is press downward kilometer by kilometer the

pressure 10 snow into lice which encapsulates the into tiny bubbles that by presenting at from the time when the snow fell thousands of years ago. the is when you look at the snow from the last 5000 to use the sea when humans began implement the same to climate. so we can see more and more met sherry in the ice. there are many ways we can measure the impact of human activity. the is a big difference between the ice here, which is almost without crevices on the front to die so that the ice over here is moving most 30 than the ice spike that

the ice is in constant motion gliding, flowing and stretching downhill towards the coastline. only now do i begin to realize that you can see where it flows the fastest by looking at the surface, there are a current flowing through gremlins frozen sea. similar to the ones found in the wilds, oceans ice floes. when the ice reaches the coast, it breaks off into the sea, the the

best match we don't yet know about the streams of ice, but we do know they are responsible for huff at the well to last device. tough. what you seeing here is the quickest die so on the planets this place here once traveled. that's 7 kilometers. yeah. that's no longer the case. now the speed is about 12 kilometers a year, but that's about 40 meters a day. if you stand out there, you can actually see the ice flowing. it's unique probably the only place in the wells way you can see this the

nobody can put landscaping here. so it is like a lunar landscapes here because the ice has withdrawn and the speed of the ice flow has increased hot. what do we have the life now when the ice recedes, life appears on the 1st knife to appear in this desolate byron place. and the recently fried from the ice me every only slow behaves differently. that much door to knows. this one had initially double that speed. oh, need to slow down again. we don't know why it's doing that. you take the, the, the, this surprised us because the temperatures on green end rising steadily my much so that's why it's so difficult to understand the ice floes is this, the sample flows coverage model is predict the sea levels will rise 60 centimeters

in copenhagen, denmark assuming that they include a margin of era of 60 centimeters. this 5 foxes to this means the city sea levels could change anywhere from 0 to 1.2 meters home. that's the amount of variation poses a serious problem of a city demo. and warning, you call that balance of the mounting and green non takes place on the coast, the other hoss through ice streams, baton talked to cut the largest ice mass on us. it's so cold that nothing mounts on the surface of the last in ice mass on, on, talked to is that foreclosed only by ice floes. everything we learn on queens ends can be applied to an talk to the 40 percent of the world population lives by an ocean and 230000000 people live less than one meter above sea level.

we have no idea how high dams will need to be to protect these populations. what i show lines will need to look like a web people or should live scientists believe it's the water underneath the ice that affects the speed with which the ice is moving. for my next expedition to join professor island hubbard, as he explores these very phenomena, the or the,

the co africa coming conflict in donna, in summer, post escalating to a very high end of the problem resources. i'll be coming, guess because of the time to change the initiative. now, office guided mediation to find the nico africa in 30 minutes on the w. the
