to harbor secrets about the future of life owners unexpired. thanks for watching the can you we are all set. we are watching to see all the to bring you the story behind the news. your own about. com biased information for free might do to me in 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 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 on 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. if you paid looked at it. yeah. i think you think there's forensic, i know it. ok if you spring,

that's cool and that's fine because i was gonna get assigned to study the ice in different ways. but those who examined it by climbing down into it can be counted on one hand. island is one of them. for the past 15 years, he has spent more than 3 months a year on the ice. and when i us don't about him, she says, i think it's the only time 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 florida 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'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 to me 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 fun. 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 moonlight 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 tent up here. is this leaving sam's down here on the pallet over there? we'll climb a little deeper every day. you don't climb down into the, on the, in one day we're a bad b k. o me and dice. fain to this region of the sheet before. and then some

surveys of the move land 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 and we'll look, see what we're in for. i have a wreck here and of 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 dikes, us 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 only escapes the ice in his 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 the theory of highly ah, she moves has been developed from small gleiss. she is in the scandinavia of the alps. i'm rarely, there comes a point where those theories no longer hold when you have big eye sheets and the very fair cars. recent measurements indicate melbourne to remains under the ice even in winter. either the channel remains

empty because of all the mountain moultrie drains away. well, there was a smooth surface of frozen water table. if this is the case, then there may be liquid want 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, right? careful that never poses in this when you go see the crack, let me 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. i think i'm able to see what i can come and have a look if you like. i know i knew far as i was and where i am. stay behind this point, all the info. you know, 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 lights that we can send things down to figure out what's going down here. we have lots of theories, advice to atlanta, very few of the versions of it. and there's a good reason why there's no absorb ations of it, cuz that's quite strange and intimidating places to go. there's inside every glass . they all address though most failed by say all the just a bit of adventure. and this is what it's about for me. that's the beauty of ice and glasses and started with the

what would be not an ice group the so you uh, i think all, you know, 10 years, much 7 a beautiful or there is

a lot of ours are coming out of okay, the huge variety back in the i'll do it in small steps. 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.

the, it's scary. it is, it makes it fun. yes. injuries are they are to be crossed. tried to turn to the right and we've done the try to enjoy it. i knew is not easy. we need to calm down 1st. we'll take it in small steps. the, the,

the, the icicles are drifting because it's so warm today. the island says says apply to about 60 meters down the

to 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 to new last year and i was good to be in state places with good views and that's 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 a film that does tend to be honest, i'm also a little relieved. the primary thing is i use that polls don't, don't you know, there are huge icicle starting there will try to avoid. i don't nervous about the roots, but all the things that you can't control me the thing when it gets to you. how deep are you going to say to me right now. it looks like a 180 meters and that's as far as i knew, nobody has ever gone that deep in total, the 118 meters, so locked with as along the

scouts you know, going down. no. 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 may have i provided. okay. i need the toilet. yes. or couldn't fail myself if i saw it's going to get ready mastery. i'm getting to know islands clocks this morning. he's storing the,

the, the, i'm not worried about me. i'm worried about those people dependent on me. i've had a good life leverage 1st day. i've got 3 lovely kids. i've had a lot of fun and a lot of adventure. this been part of it for sure. sometimes i think. yeah. well i grow. why? because i got what i have grandkids the

i'm on the wrong. 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 perfectly horizontal surface. site has found a frozen water table the all how long is the same as ever done?

it's just how do i can dive in here as i, we're going to get incredible. if you guys go to like oregon parts, it is just like nice to own cathedral samples. so massive incredible. it was a few months ago. and what we've landed on here is the water table shape i want to express the other side of that. they are rambling 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 alan 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 count realities, measurements, and test these hypothesis that there was a liquid want to down down what i find is really interesting, but the water table is so high. series says, if it's working properly, it should drain a lot water away. but it's not our predictions, but we'll see that we're always 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 work one of the oldest research stations in greenland called swiss. com. is that with his friend and mentor professor, comrades? steph. and the, the temperature still looks the range is not that that could, but that can download to data easily. but i don't know why i need to call of the hey, law center. i'm on my way home cuz i was ordered home by my employer family. so here on an airport

and we, we lost connie. at this point, i should probably explain who professor i should have is called a hutch deaf and connie as jason coles and 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. a fast. i can't wrap my head around what has happened. but connie is dead here. we're 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 ago by we start to wonder where he is going look for him. then find him in his 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 circulated 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 that there is a busted open floor of the provider that is called water underneath

and is clear evidence that something destroyed slice layer. and then it says water . the thing is that in the cold, fresh water, you're not gonna floats. we didn't know his location until it was far too late. so many people love love to come on the phone for so many people in here was a visionary for climate. he started his measurements before greenland was like the literally

st rescue workers show that respect the 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 hazard is 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 we are back at the big new law and it is much cold at this time the, this 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 water 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. the complex and far more interesting scientific please. the, [000:00:00;00] the,

this time the moon line winds its way down, like a spiral staircase, with various chambers off to the side, the, [000:00:00;00] the

ready completed the task. got to be careful, wire, fast ice. i've talked to flight crazy to become around the corner. we've got another end, right. so it's a total of 6 to meet of the

the good. yeah. we have all the it's really warm as well. where the water it's from the summer now. i mean, randy, you wouldn't want to fall off in it, but it's not cold when they have the ambient temperature via temperature, right? i see dog so that the, you have a wireless wired system, temperature,

water pressure on me for instances and hopefully that working but your fingers might be the water table got to be here. the is incredibly so it's not a matter of the that was to the drain the way at the end of the summer. but it fits, it contains energy over windsor releases that energy into the ice around it. and a 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. it's very, very difficult to bicycle environment back nothing other than an ice age. the we found mount 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 model is high predicted. in the lifespan of our children,

temperatures and sea levels will rise faster and faster until the world might well become unrecognizable. one seems like a doomsday scenario from a science fiction story is becoming reality. we must listen. so the scientists those who say we have no time to waste the nature is trying to

tell us something the, the other 77 percent coming to use. i'm monrovia checking on the relationship between this and and how i teach at the streets. we base, we have some controversial views about the role of women in liberia. yeah, rules surprised commendable men and women, women potentially waving your own, just taking care of the 77 percent in the same minutes
