i assume that's it for now, coming up off of the break doc for the next floor is to try to have freelance dwindling k share as i'm going to strategy in berlin. thanks so much for watching. we'll see you soon by the can you see 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 hub as a secret giving us a look into while future the pump that on secret runs through these rivers of mount water, which form every summer and disappear every winter, the drain into holes cold. la 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 slowed, 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 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 when every day, oh yeah. on expeditions deep into unknown territory.

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. maybe that's also 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 looks like you to full price jason box door today and jensen and alan hubbard. 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 just, just you got to think about their weight and other with the next one this year. wow. 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 see not easily 50 meters, although no, no, no, no. that's no bridge. what,

what you were standing on that wasn't say of the, 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 determine that way. door to jason, and i'm believe it's necessary to study the process through to rank jumps of ation and field status. they call it ground truth for, for to us soon. document factors, the effective input use the look of 20 years ago. you could go directly onto the ice from here. now you have to vote quite fall to reach it. no, no my golf, when you, when you will, can i see want to climb its history, the down kind of say for that that slice from the ice age,

which is more than 11000 years old. i'm gonna keep her own tough, his lights, a 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. it's 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 it will display, 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 real, some 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 of the the a warm of 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 snow for 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 for kind of 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 climax on the ice sheet. there's a come into what 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 melting 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 full and it to make sense about the competition between these 2 forms of h 2. 0 it's, it's kind of an honest old 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 wave 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 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 that extra beat or $330.00 if they totaled 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 agreements. 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, 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 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 starts to happen. you begin to see the nuances. you notice that the ice rate actually sloan, submit that it isn't one giant find plant to that it actually pillows up and down. you can see that the wind has shake 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 is still gas in here. so i'm just wondering, you know, the, we have to take this route to, to avoid these really bad curve. s, as in here,

here. then there jason enter. massage these measurements will be compared to measurements gathered 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 maybe over here, the

the 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 dig fast. 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 won't get jason honey accurate snowfall data. it's a new technology. measures neutrons reading down on the planet from space and the that 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 let's, uh uh, it did measure continuously. it's just recording the data in verse. so yeah, i think it's working. that's great. see you have a yeah. yeah, i'm really happy. i put so much effort in to this work and you know, the a lot of times it feels like it's just pure effort in your your 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 over here. 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. we didn't know that before the, the thing about ices, 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 oh that's i'm high clouds so you know, maybe that's the weather we've been told about the hello is this the match office? hi um i oppose the nice to know gala gift. uh, this is uh uh e denmark. uh and uh, we are on the inland,

dice request uh whether prognosis of the the 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 when the wind is only lighting, 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, we make the wall so will be ok. so the go down because this layers are difficult so far,

the icon help, let's think about what would happen if i'm 10. so ripped apart. we're lying 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 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 inside the 10 the off to 2 days. the storm suddenly stops as if someone flicked the switch. jason, i'm associate 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 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 reply. i am waiting for helicopter, the jason's measurement show this increased snowfall here. we can see that there is 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 quickly 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 become 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 hex 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, to, 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 or ice and ice coal research have taken up professor delta dental jensen's entire research life. or as jason puts it door that sees 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 a t tons of ice and 20 kilometers device close here to provide you some insight working through a history book. i can tell you a story about every books we started to tell them that cast is the the,

the don't to is one of the scientists who know the most about won't be ice content. us about climate history. the findings to this is that to the ice from the ice age, it's 11900 years old. each line represents the the spring of each year. the soaring stores, new spring, dust with them, and small app bubbles, foam around these dust flakes 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. 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 influencing the climate. so we can see more and more met cheery in the ice. there are many ways we can measure the impact of human activity in 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 more slowly than 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. ocean's ice flows. when the ice reaches the coast, it breaks off into the sea, the or the as much. 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're seeing here is the quickest. i slow 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. so 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 landscape period 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. you take 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 cents and meters. this 5 foxes to this means the city sea levels could change anywhere from 0 to 1.2 meters of home. that's amount of variation poses a serious problem of a student demo. and warning you call that balance of the mounting in greenland takes place on the coast. the other haas through ice streams, the baton south dakota, the largest ice mass on us. it's so cold that nothing mounts on the surface of the last in ice mass on, on talk to is that foreclosed only by ice floes. everything we land on green lens can be applied to on top to cut the 40 percent of the world population lives by an ocean and $230000000.00 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 where 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 these very phenomena, the or the,

the co applicants coming in from a post escalating to a very higher level. the problem resources. i'll be coming guess because it's time to change the initiative now office guided mediation to find the eco africa in 30 minutes on the w, the china climate type of choices of climate pioneers. one of the world's largest solar power plants is being built in mongolia. almost
