that will return the x 3 crew best and that's all for now. coming up next up film with a voyage of discovery across the huge expanse. as a vice, it's part to of a feature. looking at the threat of greenland. dwindling glasses. i'm anthony. how it, i'll have more headlines for you in 45 minute the, the goldsmith. i'm not saying in the late seventy's shlomo smiles. now make go stop bog. now. the man who had to maintain him to use light to wagner was date. was it suicide? the evidence raised to stop what really happened? january 27th on dw, 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 of join professor island hubbard, as he explores this very phenomenon, the that was the food up there. it looked like from india and i had some also to make sure you finger printing. yeah. have you paid? looked at it. yeah. i think you think there's forensic, i notice that the ok if you spring that's cool and that's fine because i was going

to get signed to study the ice in different ways. but those who examined it by climbing down into it can be counted on one hand. allan is one of them. for the past 15 years, he has spent more than 3 months a year on the ice. and when i ask, don't about him, she says, i think it's only because you can have the cold in the calm and quiet guy. ok, so he's known for doing extreme things like working in the mood. now. i need to get with them. he's fascinated by, whoops. here in tyson and he discovers things we're going to be very big toward the inside or outside. we'll say the site is all a complete surprise. yeah,

this is cross cones go a form of pilot of the royal danish and force and chief instructor for survival training on the greenland ice sheet. klaus is responsible for all safety on this expedition of why should i be the most likely to the ministry of if you know, you also know you complain, it'll be scared to believe just approach it all with respect you go to, you'll see we take this very seriously, we have our equipment, we check it again and again, if i might pester you sometimes, but everything has to be right. when we go down, you'll be more on your own and train and come with it. there is no one to come and get you. something goes wrong during their and the mueller your on your own. while i finally the,

a little fungi. that's for sure. the, you know, that tingling feeling you get and you'll bailey, when you're about to do something exciting. that's what i'm feeling right now. the,

the, the, the, the, there is several big moolah in this area. this one is the biggest, the we have 5 days to reach the bottom of that, how the plan is we make the big sound up here. this leaving comes down here. and the product over there, we'll climb a little deeper every day. you didn't climb down into the, on the, in one day or on the streets were a bad 50 k o me and dice a fain to this region of the ice sheet before. and then some surveys of the moon

lands around here, and they have to participate in this region. yeah, hopefully, we're not going inside today, right? we've just checking in with them. i'm a look, see what we're in for. i have a right to you, right? the every summer snow and ice melt along the rim of the ice sheet, the mount water, foam sapphire blue lakes and rivers.

the water flows downwards. finding small cracks and crevices. you only need a little bit of water before it will create a big hole, a move walter digs deep and wide to the the water entering the ice becomes part of the in a structure of the glass. yeah. the water flows from the surface into the ice and then towards the sea, the it acts as a lubricant causing the ice to move it as a great to speeds. imagine ice cube. so on a wet table,

the more water, the better they slide, the researchers of assumed meltwater early escapes. the ice seems late summer leaving the bottom of the ice drained of water in the winter. without meltwater the ice slides towards the ocean more slowly and keeps more of its mass, the level of a theory of highly ah, she moves has been developed from small gleiss. he is in the scandinavia of the alps. i'm rarely there comes a point where those theories no longer hold when you have big ice sheets and the very fair cause. recent measurements indicate mount bullets. it remains under the ice even in winter. either the channel

remains empty because the old amount molto drains away well there was a smooth surface of frozen water table. if this is the case, then there may be liquid warrants at both. and as well as in the ice and water will run off in winter to ah, predictions of how quickly sea levels will rise. would then be too optimistic. careful that never poses in this when you go see the crack them down here just in front of you guys. you have to check it before it go cross. this could be snow also. okay. you don't know how far the crack goshen . okay. that's. it's actually the nice dangers time it used to be up here in spring, the shapes of snow that usually covers everything well, but in all time you have a little dusting of snow and it hides things, but it's not strong enough to hold you away. it's actually a hard time to be

a 5th of the middle of the exhibits. you can come and have a look if you like. i enjoy the new fires and where i am, stay behind this points for you. the today's plan is to study only the oper meters of the how we need to get a sense of how safe it is before we start descent.

the we really have very little idea of the role of this and the role of these movements and never thousands and thousands of these across the whole i shape. we have a little bit of g, a physics data, the radar and the like that we can send things done to figure out what's going on here. we have lots of theories at biotech, atlanta, very few of the violations of it. and there's a good reason why there's no absorb items of it, cuz that's quite strange and intimidating prices to go inside every glass filled address, though most failed, likely all the just the better of the adventure and this is what it suffice for me . that's the beauty of ice in places and studying with the

what would be not an ice crew the . 2 the so you uh, how big all you know, i that, i mean i'm 10 years much a beautiful or there was

a lot of ours the cold. okay . the huge variety back into the the, i'll do it in small step. i think we will go that far today. okay. we have no idea how deep the hole is. all we know is that we each have full, 200 meter long roads. klaus. i'll go down here. yes.

okay. so it's scary. it is. it makes it fun. yes. injuries are there to be cross tried to turn to the right and lead time. the try to enjoy it. i knew is not easy. i need to calm down 1st. will take it in small steps the, the

the, the icicles are drifting because it's so warm. today the island says there's a positive about 60 meters down. the

a good old look out. a lot of stuff slowing down

the, it's huge. if you drop something and listen, you can tell it still a long way down the i still can see the bottom. it's bob deeper than expected. i think so. this is as far as we dad to go today, the chair must be 1520 makes is across the smooth lab. so we're going to

lower ourselves and then have an explore see where it goes quite in 10 minutes. i think, i think you find it a little bit exciting. can you last? yeah. it's good to be in the state places with good views. it gets uh got rid of it. the cold winds. pretty crazy. the all

of it's a strangely sign into morning. we will need that extra cup of coffee, crowns, and dial, and have decided i shouldn't join them. the reason is simple. it's not cold enough and the ice is too dangerous. i would have loved to have filmed bad to send that to be honest. i'm also a little relieved. the primary thing is i use that polls don't on, you know, there are some huge icicle starting there. we'll try to avoid that. i'm not nervous about the groups, but all the things that you can't control me. the other thing, when it gets to you, how deep are you going to say right now it looks like a 118 meters and that's as far as i know, nobody has ever gone that deep into a 118 meters. it's a lot to pass along the

south, you know, going down, i know what do you film it for me? sure. so here's the camera. i don't know if there is a scale for this, but if there is a scale from $1.00 to $5.00, what's this going to be? the tip is close to a 5 if know, so 5, that's why we won't teach you a long. it's too dangerous, or is it meant by provided? i need the toilet. yes. or couldn't fail myself if i saw the nurse? it's going to get ready next week. i'm getting to know alan's class. this morning. he's doing the

i'm not worried about me. i'm worried about those people dependent on me. i've had a good life leverage. 53 lovely kids. i've heard a lot of fun and a lot of adventure. this being part of it for sure. sometimes i think. yeah. well i grow. that's why. because i got why have grandkids the

i'm on the ball. no, it's all it after a 175 meters counts reaches the bottom. but the many pieces of ice tell them it's not safe to be here. the

greenland inland ice is usually not flat. it's cracked, fence and broken. there's only one explanation for such a perfect the horizontal surface. as i have found a frozen one to the table the oh, how long is the same i've ever done?

it's just how do i can dive in here. we're going to get all this incredible if you guys go to the organ parts, it is just like nice to own cathedral sample of friday. so massive audits and part of it was a few months ago. and what we've landed on here is the water table shape i want to express the, the other side of that. they are rumbling i guess

it's just it looks very on the plan was to drill through the frozen water table to see if there was liquid water below it. but due to the warm temperature, it's simply too dangerous to be down here. and it will take island and klaus 2 hours to get back to the top, the of the we have to come back when it's colder and the ice is safer. only then will it be possible for island to kind of realities,

measurements and test is hypothesis that there is a liquid water down down. what i find is really interesting that the water table is so high speed recess. if it's working properly, it should drain a lot water away, but it's not our protections of global sea level rise could be quite a bit off. that's a complete disaster for the coastal regions of the planet. ready the

i receive a short text telling me to call immediately. it's from jason who is in greenland to walk up one of the oldest research stations in greenland called swiss. com is dan with his friend and mentor professor, comrades, steph. and the temperature still looks the range is not that tech, but that can download to data easily. but i don't know why i need to call of the, hey, listen, i'm on my way home cuz i was ordered home by my employer family. so here on an airport, i said we,

we lost connie. at this point, i should probably explain who professor i should have them is called a hutch deaf and connie, as jason coles him, was the person who got jason into studying greenland. gracie is an ice sheet. he's been a research of a faulty is collecting data before anyone else even thought about how the climate affects the ice. at 1st, i can't wrap my head around what has happened. but connie is dead. he were working next to 10. he said, when we last saw him, i'm gonna go and check the data. he just pulled a memory card from weather station hours go by. we start to wonder where he is going look for him. then finding is tense.

we go into emergency mode, spend hours and hours like turning the camp upside down. we call to the search and rescue. the royal danish air force. they fly in. they're taking and for red. and the high resolution pictures of the camp they were, they were circling either camp. i'm looking for footsteps by the next morning we had put enough pieces of logic together to focus on one place. and we sent the ice cavers down. sure enough. there the open floor of the provider that is got water underneath and is clear evidence that something

destroyed lice layer. and then it says water. the thing is that in cold, fresh water, you're not gonna floats. we didn't know his location until it was far too late. so many people loved loved him, come on for so many people and he was a visionary for climate. he started his measurements before greenland was the headlight the

literally st rescue workers showed their respect for comrade stuff and he meant a lot to them to the the, the

i liked when you were saying the other day to about the difference between risk and hazard and i actually had to was actually google being with the difference between the risk and hazard and so hazardous, something that has the potential for harm. and then the risk is the probability that something actually would happen. i really know that you guys take those risk seriously and i can't imagine myself ever saying you can't go back there because yeah, let's get the data we are taking kind of a higher level of safety now that the accident yeah. has happened it's. it's a reminder, yeah, that we because has,

there's exist the, the thing is i feel somehow even stronger than ever that i have to go back. that's to continue these measurements that we started. i think that my life isn't too important to not take that risk. and i, i know that, like connie, people will say that this was a place where, you know, i'm dedicating my life and,

and that's what connie did the at the, we are back at the big moonlight and it is much cold at this time. the least time allan has brought along a friend, francesco soto, a geology professor. the question is whether we will still find

a frozen water table this time around. and if we can stay long enough to drill through it to see if there was liquid warrant out underneath, weren't exactly the same spot. so i'm gps position looks very different. but the devil is in the detail. the devil is always in the measurements. the field measurements and every time we look at the systems are always so much more complex and far more interesting scientifically, the copies the, this time, the moon line winds its way down, like a spiral staircase,

with various chambers off to the side, the, the camera to be ready ready for completing the

got the cable wire. fast cries ice, i talk to flight. crazy. beautiful. come around the corner. we've got another end, right. so it's a total of 6 to meet the good. yeah, we have all the

it's really warm as well. it's where the water it's from the summer now. i mean really you wouldn't want to fall off in it, but it's not. so when they have the ambient temperature, their temperature rises. a c dot, so that the, you have a wireless wired system. temperature, water pressure on me for instance, is hopefully that working but your fingers might be the water table. yeah.

ok. here's the is incredibly so it's not a matter of the that one for the drain, the way at the end of the selma. but it fits, it contains energy over winter releases that energy into the ice around it. and then lowering this interior region to continue to accelerate not just in the summer, but also in the wind. there's no going back on. it's very, very difficult to bicycle environment back. nothing other than an ice age is

the we found mountain water inside the ice, which is new and important information. it might be that the ice contains huge amounts of liquid, won't to that final ice as melted the even our best models have predicted in the lifespan about children, temperatures and sea levels will rise files to and foster until the world might well become unrecognizable. one seems

like a doomsday scenario from a science fiction story is becoming reality. we must listen to the scientists. those who say we have no time to waste. the nature is trying to tell us something, the,
