a pioneer here in the extreme north of siberia above the arctic circle he's at the front tier of ecological research this is. huge. in the hour of places i've had now soup in the pope. we get a flu. shot one more through my vishnu mogens and it's in my genes. are always new i had no notion of i want life to return here the killing of hundreds and hundreds of kilometers of this huge region resemble a biological desert complete scientists are the only species that drive their needs and let. big hour earlier but you're a bit more but make your more call my building of all those data prison camps and this government information of a prisoner very much. and now days a completely different tragedy is unfolding in the melting of the permafrost the vast underground in a sea and that stretches from siberia to alaska more than twenty percent of the planet's land area. most of the words of the world we're into money are the only place in the world where you can actually see with your own eyes more than ten kilometers of permafrost because the river has swept away the embankments what shining over there is ice the location is interesting because you can see the permafrost thawing right in front of the executive board if we could get a global warming up with the entire region that will soon look like this is the known as the icing. the moment to look for sure this permafrost this dates from the age of the mammoths. here you can see the grass roots here this is fresh organic material to see if. the disappear of the standards. alter and this is ice. oh. what most of those each of these veins each formed within a year it's given kind of the poles not the dish that if you. made the sea. will turn those trickles on the mountain face on a warm day twenty centimeters of ice can melt a year of june this summer it'll be three metres further back or more when i was these vast quantities of gas are released these they will accelerate global warming to the point that it will become on stop long as he needs it. one point six trillion tons of planet's warming carbon dioxide along in the world's palm a frost if it was a fool it would have the same effect as been the only forest on the planet two times over. because the scope of music. would mean when you see clear for at least ten years the temperature has not fallen below zero on summer nights it doesn't freeze any more need for reform in the past it was impossible to grow potatoes here they couldn't survive the night frost much rest but for years nothing is frozen at night now even barley grows here i will mention it was a modest. said gay is on a mission to restore the region's long lost ecosystem he's waging war on the tundra and taiga the two predominant ecosystems of siberia. less than ideal is full kill i mean we're five hundred metres away from my park and we've stopped here because i want to show you what it looked like before we began our experiment what to do with one stuffed it's a very hostile territory inaccessible. just the swamp area with dense thickets of scrub and roots should you pull as now we're going to the possibly and you'll see the difference it is a metre journalists. these the landscape in northern siberia as far as alaska must become step again this is still when it's a matter of restoring the original ego system has no shows to do fortunately or was it unspoiled nature regulates the temperature of the permafrost by itself being the sort of album even at forty degrees below zero on the earth's surface the temperature under the snow cover is only minus ten support at the center of this know what is an excellent insulating layer of the ground underneath doesn't freeze right much less than our pastures the animals dig for grass and trample away the snow it's like pulling your blanket off on a cold night you'd be very cold it's the same thing used to pull if you resettled large populations of herds in this environment they would trample away the winter snow exposing the ground to colder temperatures and preventing the ice from melting so quickly. even small the days. the red now we are the better for ski but that's about it typical construction many fishermen seen in the region have make hills much more of course but. that's the way for them to have a good fish in the summer and store them so it's negative temperatures here year out. just outside the park. said the instruments we see where we should measure temperature in the winter and on the depth of meter in march when what's the coldest temperature drop down to minus seven centigrade so where the snow was and ducked but in the police way we could also for any was which temple all year round and the trampled on the snow the temperature in march was minus twenty four on the same depth so seventeen degrees difference so if you make that. capital there will be skills that will prevent prevent further frost from melting or disposed ball or and so all the proceeds to buy as many decades and that's very critical because once permafrost is melted it cannot be stopped you know all this it will be going to struggle so that's why we need to create those steps quickly and that's why we need people to take action now. the first effects of the following permafrost are already visible. in cesky buildings are cracking and subsiding because the ground has become too unstable. cesky is the nearest town to the reserve a two hour boat ride away. life here in the coldest inhabited place on earth is half. the town isn't even accessible by road only by plane and there are just two flights a week cesky has lost three quarters of its inhabitants since the soviet union collapsed lenin still overlooks the twenty mahama it's a place haunted by the case of the past. year skinny guy i shall ask is unique he was the strategic starting point for expeditions to the soviet arctic three this was the best place to earn money and enjoy a high standard of living but after the collapse of the soviet union everything went under within just a year in the past there would have been fifty ships here at any given time now there is just one of. them. back at the research station dumper. this is what i said again and nikita live foreign scientists also conduct research here in the region of. new nikita has taken over from sam gay as head of the research station the reserve is funded with subsidies from european and american research programs coverage a quarter but i guarantee. you that wouldn't baccarat off. a team of researchers from the us is currently on site for two months everyone meets up in the evenings to eat together. heather alexander is researching the growing incidence of forest fires yet another consequence of global warming it's a seven students here in siberia. i feel like family now i mean after many many years and they have been so help for the for me and earth not only in terms of logistics but also just helping me think about the science and helping me understand how the system works and so you know we're all very concerned with pick up during the years to the right because this little island which is about a hundred meter wide there is straight for us to the north pole the snow and supply are to conserve where the moving picture is policed. how's it going to voice. the reindeer how does a cheetah and indigenous people they live in the tundra with their hands. normally the animals do so for their meat but today a different face awaits them. but what do we do next. go to the food first the herd has to be surrounded so the animals can't escape. me. i. think it has the most by and transport only animals with which they populate their resentment by themselves strangely are the easiest and. to come by they can be collected by boat from the tundra only to. another twelve hours in the boat then the rain team will be released into the wilds of the resent the huge. rigging the open so. they are all stressed of course you know tell us more to me with the snow and ice pitcher on the same. bill now and tell them what the most about. and then they will be much better. i don't i need to break open up. a few. we have heard it a multitude of foreigners but a complicated thing to build a park here so that's a hole was a challenge so what we face today was oh absolutely nuts and it's once we went through on the go i want to list on these same boards to pick up the moscow oaks it was seven days to go toronto island because of the open arctic ocean that we were fourteen drifting through some goes through the dresden ice and then on the way back we had a horrible storm a full two days without reason in the open ocean so it was quite the expedition then next year it was going sailed so stupid when five days driving through into russia it was pretty pretty complicated and extremely extremely dangerous trip my truck was the last one that season was friend and we did just because. trucks which were driving behind the drugs well the nicest thing about my work is not that i'm still alive but suppose the thing to. come call for me in part of the little food. you see most are a fearless family. his wife and their three daughters live with him in the research station until the pound the night sitting in winter they go to school early no c b m school four thousand kilometers away. but all. the reindeer have finally arrived in pleistocene park they'll be released soon but before they join the other animals they spend a few days in a paddock getting a climatized or. docked and they're very valuable your chair felicia watch your head my monitor. have. all you. thank goodness and. next year will be no less demanding nikita's planning to import bison from the us. a regular kind of science experiment experiment so work of thousands of software and really was. important but on a global scale that's a tiny effort which is literal and in order for us too. make this kind of influential and quite work with you would have to make it on a very big scale so pretty much what we aim for is we want to make high productive stuff across systems everywhere on the planet well most places in the clinic which are not occupied by humans in the future where is why governor ordered the i don't know maybe ten thousand effect or a system which is over the function if i will be inside the smallest there from that point because it would expand faster. to resurrection of the woolly mammoth in the u.s. geneticists at harvard a hard at work on this project could this normally extinct species really be brought back from the dead to stampede across siberia said gay hopes to use a neat wallace. i need maybe shift to souls of mom's for beginnings but no one. don't give me. give me so much one was disposed to want. but i believe it's this is good chance it's really you course fortune elephants sort of life chill no gentleman moments exists in all of it i'm a force and gentleman exciting to develop self honest maybe if you don't need to make a start for mamma's maybe we need change in the janabi of malden early fonts for adaptation in supposed quite. unknown stroking can only be abandoned radar antenna is manmade. everything else here is preternaturally vast the non-state beaches will sanjay's vision and their conviction to gently nature can save mankind. by force of the most credible and off that much i care about you is way more and i have kids and i want them to be with a better planet in the future and. that's why i did it first it's difficult for me but for it's affected it's real yeah it's basically got one of the weeks for all human just the wife and it's better than developing a future past. to look good to have more people to join the workforce so you
