push notifications for any breaking news. you're up to date of an extra documentary series on the threat of greenland. dwindling. i should stay tuned for that. so after a short break, i'm from in the team here ex, watching. take care the can you hear me? we are all set we are watching to see all the to bring you the story behind the new your own about palm by as information for free might do to me in the

agreements ice sheet hobbles, a secret giving us a look into while future the, the pump to then secret runs through these rivers of mount water, which form every summer and disappear every winter, the drain into holes cold. moving on of this one is 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 what's up then the 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 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 might well disappear. it may be that. so we'll say what's happening now only now it's not just my little, well that's punishing the terminator to the port. the number is

8.8 meters. now this will start to use a full price. jason box door today and jensen and alan habit. i'll be joining these 3 extraordinary professors into explorers 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 there, but another with 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 15 either or? no, no, no, no, no. somebody puts us no bridge. well,

what you were standing on that was and say no the, these, these take lives the, 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 determine that why daughter, jason and diamond believe it's necessary to study the process through the rank dumps, evasion, and field start is they call it ground truth full for 2 or soon becky contract is the fact to employees the new call 20 years ago, you could go directly onto the ice from here. now you have to will quite fall to reach its normal golf where you, when you will, can ice, you work through climate history, the down kind of say for that that size from the ice age,

which is more than 11000 years old. and i'm gonna keep her own tough his life to color dice younger than 11000 years from the integrated show periods. welcome or the east for for many reasons. so you can stand with one like in the ice age uses. i'm with the other like in the, into glacial periods like this. i'm standing here, it's a very dramatic moment in climate history. you know what you might have. so this is just one instrument of many here we've been studying this place here for over a decade. now, so we have a pretty good idea of a higher display. see a b hayes i think it's important to come here and make the measurements and just not sit beyond the desk and download your data real, some satellite the, 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 a home of weld also means a more humid weld with more precipitation. how will this affect the ice? how does most snow and rain affect the melting process it?

sure 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 over a? 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, 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 data. well, there's some that's coming through dammit, this is professor conrad stuff and jason's mental early in his career, a pioneer in climate research. jason was one of the office of the u. n's 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 crevices jason had shown me not visible. now the in order to find out how fix 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 that extra meter 330 . 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 on the video and so forth. yeah, definitely people to make good japanese down there. yeah. i hope 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 of this extra heat. it's 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 starts 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 at 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 is still gas in here. so i'm just warming up the we have to take this route to avoid these really bad curve. s as in here,

here. and there jason enter. massage these measurements will be compared to measurements counted by a nasa airplane of 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 media 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, it's hard. the, you know, it makes you able to do the best. it's either speed metal or of those to somehow but you know, it 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 will get jason honey accurate snowfall data. it's a new technology. measures neutrons reading down on the planet from space and the snow in between it blocks 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 in 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 bursts. so yeah, i think it's working. that's great to see. you have a yeah. yeah, i'm really happy. i put so much effort in to this work and you know, in the 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 are 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 see the maybe that's the weather. we've been told about the hello is this the met to office? hi, um yeah, i oppose the nice to know gala gift this hosa. he denmark

and uh we are on the inland, dice request. uh whether prognosis of the he said 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. in the wind is only one, 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 or it's really made for that's why we make the wall . so we'll be okay. really the go down because this layer so difficult so far,

the icon help that's think about what would happen if i'm 10. so ripped apart relying here in the middle of the ice sheet is nothing but honest sleeping bags. okay . 25 knots in the morning. in gusty,

the a little bit stronger. building to about 40 knots. i have no idea how strong faulty not since i'm given a situation. i'm not about to ask the of the do you want more coffee?

looks like we're getting through all you can really do is inside the after 2 days, the storm suddenly stops. zip. someone flicked the switch. jason and massage. she can finish that final snowed rollings and i noticed that we can see water for the 1st time. the end of greenland ice sheet, we made it to the final destination, the

safely emitted 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 or a fly? i am waiting for helicopter jason's measurement show there's increased snowfall here. we can see that there's a gradual increase in the 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 uh, 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 sheets 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 of his research on

the ice. while the mature tree will have a 100 kilos 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 a 100 tons of hard to the is going to change the pressing in the wind. read a little bit about our personal company footprints and what we did, you know, i think most people are very eager to just 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 daughter daniel 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 guys coincide and now they're going to pull out with the b. we have more than 80 tons of ice and 20 kilometers device, close here provider. the 2nd site working through a history book. i can tell you a story about every books we saw appetite on that campus is the, the,

the don't to is one of the scientists who 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 line represents the the spring of each year. the soaring store no spring dust with them, and small app bubbles, foam around these dust, lakes, and 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 are as low as snow falls now upon zane or of snow is press downward kilometer by kilometer the pressure 10 snow into lice which in capsulated via into tiny bubbles that by

present i think. yeah, from the time when the snow fell thousands of years ago, the is when you look at the snow from the last 5000. here's the sea when humans began influencing the climate so we can see more and then more met cheery in the ice. there are many ways you can measure the impact of human activity in the top. it 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 closely to the ice back that

the ice is in constant motion gliding, flowing and stretching downhill towards the coast line. 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 floods. when the ice reaches the coast, it breaks off into the sea the, [000:00:00;00] the,

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

nobody can pull 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. and 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 in every ice flow behaves differently. that much door to knows. this one had initially double the speed need to slow down again. we don't know why it's doing that. the 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 of home. that's the amount of variation poses a serious problem of a city demo and warning you call that balance of the mounting in greenland takes place on the coast. the other haas 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 land on green lens can be applied to on top to the 40 percent of the world population lives by an ocean and $230000000.00 people live at 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. on my next expedition to join professor island hubbard, as he explores this very phenomenon, the or

the 77 percent. talk to about 200 episode stars from across the continental good group. and i got and last but not least, just like you did. so i do indeed have a use of it. so i'm assuming you guys the 77 percent in 30 minutes on the d. w. try and repeat after me alarms there will again to

god read sherwin, leo, google gods by its full screen gauge, folk gab, acquitted to pools. i'm to say leo, for folk is the longest name of the place in europe and its wells. we should definitely try to pronounce at least 109 in 90 minutes on d w. the we said there about never giving up every weekend on

d w the, this is dw and use live from berlin. ly ching tag wins taiwan presidential election . the routing democratic progressive party's candidate emerges victorious over his 2 opponents for the presidency his election. we'll set the trajectory for tense relations with china for the next 4 years. also on the program, the u. s. military strikes here, 3 targets in yemen for a 2nd day is he needs 5 to retaliate. and warren dash us and british interests are now considered legitimate targets. the
