00:31In April 2020, China's National Survey and Mountaineering Team
00:38Surveyed Mount Chomolama for a third time

01:22Mount Chomolama, standing on the top of the world, is covered by snow all year round
01:30It is not only the summit of the planet, but also a cradle of glaciers, which indicate the health of the world's climate
01:48And as the highest water tower on earth, it is also a source of life

02:13Early in the morning, Chen Pengfei and his colleagues are busy making preparations.
02:43They are packing down jackets, sleeping bags, cotton quilts, tents, and even a freezer. These are the items they will need to live on Mount Chomolongma for the next few days.
02:59This time, the珠峰 study is mainly about 8 members, and the needs of the field of research.
03:06The most important work is to be able to do the air-to-feed, and the air-to-feed, and the air-to-feed, and the air-to-feed.
03:14If he is going to go to the 12th of the night, he will be able to go to Lhasa.
03:20In 2017, the Chinese Academy of Sciences initiated a comprehensive survey
03:35of the Qinghai-Tibet Plateau, in which a survey of Mount Chomelangma will be an essential part.
03:42In it, the Academy's Northwest Institute of Eco Environment and Resources is responsible
03:51for conducting scientific and quantitative investigations into climate change in the
03:57Chomelangma region, as well as surveying its river systems.
04:12Mount Chomelangma, the highest peak in the Himalayas, lies at the southern edge of the
04:18Qinghai-Tibet Plateau.
04:33From the Kyawu La Pass in the Shizong Autonomous Regions, Tingri County, you can see four Himalayan
04:39peaks of over 8,000 meters.
04:46This survey will start by gathering ice and snow on Mount Chomelangma.
04:54Kong Shi Cheng is a renowned Chinese glaciologist and deputy director of the Northwest Institute
04:55of Eco Environment and Resources at the Chinese Academy of Sciences.
05:01Kong Shi Cheng is a renowned Chinese glaciologist and deputy director of the Northwest Institute
05:08of Eco Environment and Resources at the Chinese Academy of Sciences.
05:11Since 1997, he has been to the Chomelangma region ten times for research.
05:18In 2004, he set up glacier monitoring devices at altitudes above 6,000 meters in the Chomelangma
05:25region.
05:27After 17 years, what changes have there been?
05:49Although Kong Shi Cheng is not accompanying the team this time, he is the major planner and
05:54organizer of its survey project.
05:56The natural weather is also very important.
05:58The urban areas of the world are the most dangerous areas, and the most dangerous areas of the
06:03world has been to be able to change the environment.
06:06The natural areas of the world, the areas of the world are the biggest danger of the world,
06:09and the impacts of the world of the whole world.
06:15Unlike the Antarctic and Arctic, which also lock up a lot of frozen water, the Chomelangma
06:24region has lush forests in its southern valleys.
06:29Subtropical, temperate, and alpine desert climate zones exist a short distance from
06:38each other, and each have their own distinctive flora and fauna.
06:45Lying in the hinterlands of the Eurasia continent, the mountain is also not far from large human
06:51population centres.
06:54Local climate change may therefore impact the survival and development of many millions
06:59of people.
07:07The average age of the Chomelangma Glacier research team is below 35.
07:13Many of its members are post-graduate students.
07:17Chen Pengfei is the most familiar with the Chomelangma region, and has participated in five previous
07:23surveys.
07:25So he was chosen to be the leader, arranging schedules and taking care of the team.
07:32Chomelangma Glacier research team is the first time to take care of each other.
07:38He is also a challenge for me to take care of each other.
07:44The ones who are disappointed in the current time are the best, and most important
07:46people are with others.
07:47And we have to be able to take care of each other.
07:48On the outside, we always say that the safety is the first place.
07:51Especially in the Chufeng area, you don't know what time it will be.
07:58We have to go down two days.
08:00If we go down one day, we can go down one day.
08:03We still have to do work.
08:04We still have to go down one day.
08:05That's seven, eight days.
08:06Maybe eight days.
08:09Upon their arrival at Lhasa, the capital of Shizong,
08:13at an altitude of less than 3,700 meters,
08:17the researchers grow drowsy.
08:19This is a minor symptom of altitude sickness.
08:23On the Qinghai-Tibet Plateau,
08:25with an average altitude above 4,000 meters,
08:28the oxygen concentration in the air
08:30is only two-thirds of that on the planes below.
08:33Oxygen deficiency can cause excessive fluid in the lungs and brain.
08:38The only solution is to avoid strenuous exercise
08:41and wait for the body to acclimatize.
08:44Often, the key is simply persistence.
08:50From Lhasa, the team proceed westward,
08:53along the Yarlong Zhangbo River.
08:55Suddenly, they stop.
08:57The Master of Tsukong
09:03as the Program and the Khrushong
09:04a lot above the study.
09:05To the East, the Yarlong Zhangbo River
09:06is a field to take a deep breath.
09:07It's a field to take a deep breath
09:08and move to the right through.
09:09A field to take a deep breath
09:11and then move out of the water.
09:15A field to take a deep breath.
09:16Although the team's study focus is the water environment and climate change of Mount Chongmelangma,
09:23the Yarlangzangbo River is an important element of the local climate system, too.
09:28It is the largest river in Shizong and the highest major river in the world, also given the name Heaven's River.
09:35The majestic mountain and the powerful river stand side by side, inevitably exerting influence on each other.
09:46So the research team needs to collect water and soil samples here, and compare them with the samples taken previously,
09:55to analyze changes in the local water environment.
10:16In the Chongmelangma region, most rivers are formed from the meltwater of snow and glaciers.
10:25As altitude rises, temperature drops, and snow brought in by the Indian monsoon is compacted into solid ice,
10:32which forms into glaciers along high-altitude valleys.
10:38In the Chongmelangma region, most rivers are formed from the meltwater of snow and glaciers.
10:44And snow brought in by the Indian monsoon is compacted into solid ice, which forms into glaciers along high-altitude valleys.
10:57Surveys of temperature and precipitation changes in alpine regions are based on studies of glaciers,
11:03which fill the bottom of valleys and ravines throughout Mount Chongmelangma.
11:08They include 15 enormous mountain glaciers that measure over 10 square kilometres each.
11:16Near to China's Chongmelangma base camp on the Big Mountain's north slope,
11:35there is a Tibetan Buddhist monastery named Rongbuk Monastery.
11:39Small in size, it is often called the world's highest temple.
11:48The creek down from the temple is the Rongbuk River, which rises from the well-known Rongbuk Glacier.
11:59In recent years, the glacier has shrunk dramatically.
12:03Lower in the valley, only isolated fragments are left.
12:08With local temperatures rising, the Rongbuk Glacier's intact part has retreated to above 5,600 metres.
12:21Its total area is still around 86 square kilometres, making it the largest glacier in the entire Chongmelangma region.
12:29Higher up, it is actually made up of three glaciers that converge.
12:35The East Rongbuk Glacier originates from the ice wall of the North Cole, at an altitude of more than 7,000 metres,
12:44and joins another glacier which itself has been formed by the convergence of the Middle and West Rongbuk Glaciers.
12:51From this point on, it is called the Main Rongbuk Glacier, which measures about 23 square kilometres.
12:59In 1960, when a Chinese mountaineering team first arrived at Chongmelangma's north slope,
13:05they were dazzled by its gigantic crystal serec.
13:09On the 25th of May, the
13:35research on the Rongbuk Glacier was a major focus.
13:41The first Chinese expedition to climb Mount Chongmelangma travelled along the Rongbuk Glacier
13:46and opened the mountain's north slope route.
13:49It is this route, 61 years on, that Chen Pengfei and his fellow team members will follow.
14:03Upon their arrival at base camp, they set up small tents.
14:08Their down jackets and outdoor equipment are not as heavy-duty as the 2020 Mount Chongmelangma Elevation Survey that made it all the way to the peak.
14:23But these young men are not lacking in dedication.
14:29After resting for a while, they begin preparing for their upcoming monitoring and data collecting mission.
14:35Their destination is the Rongbuk Glacier, as a representative example of the region.
14:41The
15:04A glacial till is the debris of a glacier, mixed with gravel and mud.
15:21It accumulates downstream as the glacier flows and melts.
15:26Though looking unimpressive, it is significant geological evidence for studying a glacier's melting speed.
15:34In general, if the aircraft is higher, it will be higher than the glacier.
15:41If you fly too low, it will be higher than the glacier.
15:44But you need to fly a very long distance.
15:47We don't have so many of them.
15:49So we have to choose a suitable altitude.
15:52For example, if we fly 200 meters, it can reach 5.4 meters.
15:59Gao Tan Guang is an associate professor at Lan Zhou University.
16:03The customized drone he has brought can continuously shoot photos and videos at a fixed altitude.
16:10It will then use satellite positioning to patch the images together to present the morphology of the Rongbuk glacier.
16:18This is indispensable data for climatologists and ecologists to monitor its retreat.
16:25Yes.
16:26Here you are.
16:27Here you can find out the
16:43It can be a high level of temperature.
16:45It can be very simple.
16:46It can be a high level of temperature.
16:48It can be a high level of temperature.
16:49After we did this,
16:51we did a couple of months in the next year.
16:55We did a couple of tests.
16:57We did a couple of tests.
16:58We could see that the temperature of the cold water
17:02will have a lot of temperature in the cold water.
17:13Monitoring has shown the glaciers on Mount Chomalunga's
17:18North Slope has shrunk by 30% since the 1970s.
17:29This is a 1975 video featuring the Rongbuk Glacier,
17:33shot by photographers from the China's central newsreel
17:36and documentary film studio.
17:39For the team, walking on the glacier
17:42is like stepping into a wonderland.
17:47It is clear that the Serac was located at a lower altitude
17:50and was much larger in size.
17:53The tallest ice block was nearly 60 meters high,
17:57dwarfing the tiny figures of people beside it.
18:09Forty years later, however,
18:11when the filming team arrives at the same spot in the same season,
18:15they find that the ice tongue of the Rongbuk Glacier
18:18has been replaced by gravel,
18:20and the Serac has retreated to an altitude of above 5,900 meters.
18:25From the early days, the large-scale melting of Mount Chomalunga's glaciers
18:44aroused the concern of Chinese scientists.
18:47The Chinese Academy of Sciences set up a comprehensive research station
18:52for monitoring atmospheric and environmental changes on the mountain.
18:56because today is the end of the month,
19:06and the last day is the most busy day.
19:08and the last day is the most busy day.
19:09We need to go to the checkpoints and download the information.
19:11We need to go to the checkpoints and download the information.
19:13Xijianhua's home is in Beijing.
19:24He first came to the Chomalunga station eight years earlier.
19:28Every year he stays and works here for at least seven months.
19:32Despite the harsh conditions,
19:34he is happy with his life as a resident of Mount Chomalunga.
20:04Xijianhua is in charge of six observation sites
20:29between 4,300 meters and 6,500 meters.
20:33He regularly goes to them to collect their data
20:37and compares statistics on aspects of local climate
20:40and environmental change.
20:46波动观测系统,它主要测的那个内容,包括比如说风,温,湿压,便是。
20:51然后就是太阳辐射,水气的二氧化碳,甲烷,三维风速,土壤温度,降雨量。
20:59基本上这五千两百米的这个设计都能下载到。
21:03通过这个长期设计的积累,来分析该地区这些圆巷因素的变化。
21:16A glacier's size remains the same when the rate at which it melts and at which snow falls
21:23on it are in general equilibrium.
21:28Once the equilibrium is broken, the size of the glacier will change.
21:37Monitoring records show that over the past eight years, the average temperature of Mount
21:41Chomalangma's north slope has risen by 0.3 degrees Celsius, accelerating the melting
21:47of its glaciers.
21:49Snowfall, meanwhile, has barely changed.
21:58More surprisingly, the average temperature on Mount Chomalangma is rising at twice the
22:03speed of the global average, presaging a massive and inevitable glacial retreat.
22:10In this investigation of the Rongbuk Glacier, surveyors will not only keep track of the melting
22:21speed with drones, they also plan to install a few monitoring cameras to obtain the real-time
22:28data on glacial changes, a first in the history of Chomalangma surveys.
22:33Li Shengnan focuses the camera on the glacial lakes formed by the meltwater of the Rongbuk
22:34Glacier.
23:05When they warm up, the camera can record the size expansion of the lakes and the speed
23:10at which the water level rises.
23:12It can also monitor and predict potential natural disasters caused by glacial meltwater.
23:18The Rongbuk Glacier melts near to the Mount Chomalangma base camp, and its meltwater flows down
23:30from there to irrigate agricultural fields and pastures.
23:49If the water level of the ice lake rises too fast, it may be a threat to the safety and property
23:56of villagers living downstream.
24:01Exploration of the water level
24:02In the winter, there will be a plenty of amount of floods.
24:03The water level of the water is applied.
24:04The water level of the water level is located on the initial floor, within the rain.
24:05когда the water level increases, it can affect the right to the water.
24:06The water level of the water is went astray and burned down.
24:07In the storm.
24:08It can affect the right to the water level.
24:09This is a free and the water level of the water.
24:10It can affect the right to the river.
24:11It might be thought that the Qinghai-Tibet plateau at high altitude,
24:39with its freezing and arid climate, is not good for growing crops.
24:44The central and eastern parts of the north foothills of the Himalayas, however,
24:49are agricultural zones for highland barley and beans.
24:54Spring is a busy season for farmers.
24:58Even unruly yaks are recruited for farming.
25:05Water is the source of life.
25:07However, as the Earth's climate warms,
25:10the melting of glaciers not only disturbs economic activity and life downstream,
25:15it also has a profound and far-reaching impact
25:18on their surrounding region's ecological, geological, and oceanic environment,
25:24and even on the long-term prospects of humanity.
25:28Particularly in the Himalayas, our planet's highest region,
25:32even small events can trigger global repercussions.
25:35This is why scientists are paying so much attention to it.
25:39It is commonly believed by scientists that large-scale glacier ablation from polar regions to the Himalayas
26:04is a consequence of global warming.
26:17In fact, the Earth has a prehistory,
26:20slowly gone through cycles of ice ages and interglacial periods,
26:24between which the largest temperature differences have reached nearly 100 degrees Celsius.
26:29Each alternation between a snow planet and a water planet has normally lasted a few hundred millions of years.
26:39Cycles involving smaller temperature changes have been more frequent.
26:43As the temperature rises this time around,
26:56some coastline cities and islands may be completely submerged.
27:00paleontological research has shown that the first mass extinction on Earth,
27:23440 million years ago in the late Ordovician period,
27:27was caused by global cooling.
27:28This reduced the total number of species by 85%.
27:39Conversely, after the ice age that followed,
27:50the global warming that reheated the planet was also a calamity to animals and plants
27:55that had evolved for life in the cold.
27:57The mighty mammoth, for example, began migrating to the Arctic region 20,000 years ago,
28:09as the planet warmed.
28:13After struggling against shrinking habitat for 16,000 years,
28:17it finally died up.
28:18What influences the temperature of the globe?
28:36Based on current studies, the two major factors are the sun and the atmosphere.
28:41The sun fuels the activity of organisms, while the atmosphere prevents the Earth from being burnt by solar radiation.
29:01Substances in the atmosphere, such as carbon dioxide, absorb and keep in the Earth's heat,
29:07to maintain a balanced temperature, which is the greenhouse effect.
29:19Once the balance is broken, either the Earth will absorb less heat,
29:23or excessive carbon dioxide will reduce heat radiated,
29:27turning the planet into either an ice world or a greenhouse.
29:30Currently, the Earth is warming up, and even ice and snow on its highest mountain is being affected.
29:44The Chomulungma survey aims to find out exactly what is going on.
29:48After finishing their basic information gathering around base camp,
30:04the researchers set out for the source of the Rongbuk Glacier, at a higher altitude.
30:08Except for Chen Pong-fei, most of them haven't come to Mt. Chomulungma before,
30:19nor received professional mountaineering training.
30:28The Rongbuk Glacier, 23 km in total length, will take them two days to traverse,
30:33even with yaks to carry their luggage and equipment.
30:42In the high-altitude air, they need to stop and rest frequently,
30:46all the while breathing deeply and fighting fatigue.
30:50They also need to beware of hidden crevices, which may be dozens of metres deep.
30:56As their arduous journey progresses, they are aware that every inch they climb
31:01is a new personal mountaineering record.
31:06To reach the Sarek Zone of the Rongbuk Glacier, they must ascend to an altitude of 5,900 metres,
31:12and traverse a 6,000 metre mountain ridge.
31:18But the beautiful crystal wonderland around them rewards their persistence.
31:22The documentary filming team shoots footage of the surrounding ice formations,
31:34which are elegant, magical, and stunningly beautiful.
31:38For the researchers, meanwhile, this ice contains enormous ecological information.
31:56The research team's goal is to reach 6,000 metres, where they can collect more first-hand ancient evidence
32:20on climate change.
32:25Interestingly, this forbidden zone is by no means empty and silent, but full of vitality.
32:37Since departing from the 5,200 metre base camp, birds, such as alpine choes and Tibetan snow cocks,
32:44have kept the team company.
32:55The Tibetan snow cocks, athletic and sleek, is a welcome sight.
33:04Alpine choes and snow pigeons can even fly to an oxygen-deficient altitude of 6,500 metres,
33:11gracing the camp that is referred to as the devil's camp.
33:20More permanently than visiting birds, in the gravel and tills,
33:24an inconspicuous creature inhabits the mountain slopes at 6,000 metres.
33:30It is the Himalayan jumping spider.
33:34Originally, it was thought such spiders were carried in by the wind.
33:38But in fact, they are residents here, feeding on smaller insects and the debris of plants and animals.
33:46The Himalayan jumping spider, in fact, is one of the highest-dwelling animals in the world.
34:00Although global warming will, on balance, be a disaster,
34:03temperature rises underway may enlarge these alpine creatures' zones of activity.
34:22The last camp of the research team is located within the realm inhabited by Himalayan jumping spiders,
34:29at 6,350 metres.
34:33Though altitude sickness is depriving the surveyors of appetite, they have to take in calories.
34:45The researchers must overcome their altitude sickness to complete their sampling and data collection.
34:50The episode reminds the filming group of when they filmed the Chomalangma surveying team,
34:58who conquered Mount Chomalangma one year earlier.
35:07To gain enough energy to make it, the surveying team also had to force themselves to eat.
35:12As professional mountaineers, the 2020 team were used to the harsh conditions.
35:24These young investigators are not as hardy, but they must nevertheless endure.
35:42They are quite good.
36:05This is the third time the filming team have climbed to 6,500 metres,
36:09after last year's shooting of the Elevation Survey Project.
36:14This time, their aim is to shoot rivers and ice instead of mountains, although, as before,
36:20they are also documenting the dedication of the researchers.
36:40The Qinghai-Tibet Plateau is a vast, high-altitude region, pushed up by the slow collision of the
36:46Indo-Australian Plate and the Eurasian Plate.
36:51The Himalayas, at the centre of which lies Mount Chomalangma, are on the boundary of the plates,
36:57stretching from east to west for nearly 2,500 kilometres.
37:01With only 50 million years since the two continents collided and started pushing them up,
37:16the Himalayas are one of the world's youngest mountain ranges.
37:23During this time, the Earth has been through multiple freeze and thaw cycles.
37:27About 2.5 million years ago, the Quaternary Glaciation started.
37:45The Rongbuk Glacier, like other glaciers on the Qinghai-Tibet Plateau, first appeared during the
37:50Quaternary Glaciation. Later on, it underwent expansion and retreat as temperatures changed.
37:58But the average depth of the ice cover remains 120 metres, with the thickest part reaching 300 metres.
38:06Under the ancient ice layer, rich information on pre-stormic climate cycles lies waiting to be discovered.
38:14We have two ways to research.
38:16First, we have to monitor the ice cover for the ice cover.
38:20The ice cover has changed how much of the ice cover has changed.
38:23This is a change in the宏观.
38:25Secondly, we have to research through the ice cover of the ice cover.
38:28For example, we have to collect the ice cover.
38:31Because the ice cover is a solar system called the solar system.
38:35It is a solar system called the solar system.
38:37We have to collect the ice cover.
38:38We have to collect the solar system and the solar system.
38:41We have to collect the solar system and the solar system.
38:44We have to collect the solar system and the solar system.
38:47Early in 2013, Kang Shi-Chang led a research team to take an ice core sample
38:53at an altitude of 6,500 metres on the Rongbuk Glacier.
38:57The ice core has provided scientists with invaluable insights into the climactic conditions
39:03of the Chomelangma region over the past 2,000 years.
39:07This is very obvious.
39:09From this area, we can see some black objects.
39:12These black objects are black.
39:15This is the area of the wind,
39:17and the water that we have to collect the solar system.
39:23We have to collect the solar system.
39:25If you look at it,
39:26you can see it in the air.
39:28You can see it in the air.
39:30You can see it in the air.
39:31You can see it in the air.
39:33You can see it in the air.
39:34What excited Kang Shi-Chang was his discovery from the analysis of the ice core
39:40of evidence revealing the cause behind our current period of global warming.
39:45From the Chomelang region to the earth,
39:48the most simple proof is that the winds are still in the air.
39:52This is a bad effect.
39:54In the second phase, we are able to see the Chomelang from the coast of the sea.
39:59The past few years, it is a big impact.
40:02We can see the past two hundred years,
40:05the wind-strips not higher.
40:07The wind-strips has reached 415 ppm.
40:13This has been almost four hundred years.
40:14is not seen.
40:16So, in general,
40:18today's fast-forward
40:20is caused by our human population
40:22and it is not a natural movement.
40:24And this change will bring a lot of consequences,
40:28such as extreme weather weather,
40:30such as the city-wide flooding.
40:32So this is our human population
40:34that causes fast-forward.
40:36And this fast-forward change
40:38will bring a lot of consequences.
40:44After a restless night
40:46at the 6,350-metre camp,
40:50the next morning the young researchers
40:52fight off altitude sickness
40:54and get to work.
40:56It is a sunny day after the snow,
40:58and they hope to complete their data gathering
41:00and sampling as soon as possible.
41:02Yinshu Fung is
41:28Chen Xiu Feng is in charge of air sampling and analysis
41:32to determine how human activities have impacted air pollution
41:36around the Chomolongba region.
41:43Hu Jiao Fu and Wang Xiaoyong climbed to a platform
41:47near the campsite to conduct a 3D scan of the glacier.
41:583D scanning photos have a higher definition
42:02and larger information content than aerial photography.
42:06Processed with professional software,
42:09they can be used to discern subtle changes in the glacier.
42:28They can be used to find a high-level information,
42:30which is how high-level information is.
42:32Even though the weight is very high,
42:33it can be reached at the level of 10th grade.
42:46Meanwhile, Chen Pengfei and his team member,
42:49Hu Junming, are leading a group to cross the Serrat.
42:54They are going to the East Rongba Glacier Pass
42:57at 6,500 meters to collect snow samples.
43:0817 years earlier, Kong Shi Chong, their mentor,
43:12set up surveying poles there to monitor changes in the glacier.
43:17They have long since disappeared.
43:21It is likely the poles were washed away by melted snow,
43:25an indicator of the urgent need to investigate
43:28and tackle climate change.
43:35If the breathtaking glacier one day disappears,
43:38it should not be because we were ignorant of what was happening.
43:41Further observation and study will reveal not only how
43:54Chom Langma's climate works, but also how its water systems are formed
43:59and how they are evolving.
44:02This is a landmark investigation.
44:11The survey will reveal, in fact, how the mountain influences weather
44:15as part of the whole Himalayan range.
44:25As the highest peak in the Himalayas,
44:27it is an integral part of the Qinghai-Tibet Plateau
44:29and the wider geographical environment,
44:31especially for weather and water.
44:33To analyze the influence of atmospheric circulation
44:47and the geological environment on Mount Chom Langma,
44:50researchers need to look at the wider picture,
44:53taking into consideration the whole Qinghai-Tibet Plateau.
44:56The mountain is now on the Qinghai-Tibet Plateau.
45:07We know that the Ahma-Lanjama and the Qingzang island
45:10is the 10 largest wave of international air.
45:12Especially in the Indus and the Hone Sea,
45:16the water is very large and the water in water.
45:18So in the future, the water will gradually reduce
45:22It will cause our economic economic use of water in the next day.
45:39Glaciers and ice caps store nearly 75% of the world's fresh water resources.
45:48Besides the Arctic and Antarctic,
45:50the Qinghai-Tibet Plateau, which is called the planet's third pole,
45:54has one of the world's richest glacier resources.
46:00Yet these resources are now threatened by global warming,
46:03with the region's glaciers shrinking by 140 square kilometers per year.
46:08What will happen if Mount Chumulungma, the natural water tower of China and Asia,
46:24stops replenishing the rivers rising from it?
46:26The Yarlung Zangbo near Mount Chumulungma is one of them.
46:33While the research team is still busy sampling and collecting data,
46:51the filming team is called away on another assignment.
46:54They will go to the source of the Yarlung Zangbo River in Nigari Prefecture
47:01to film a second group of scientists,
47:04who are investigating Himalayan river systems.
47:07As they return to base camp,
47:17the team members find their skin has been burned
47:19by harsh, high-altitude sun rays.
47:22Usually it has a different Gottaier Parkiers.
47:25We are getting undue into the royal waters.
47:27With the heart of China that turns out there
47:29we can don't.
47:30We only have signals such as the Completely-fitted ‑
47:31No, the Environmental Financial Church.
47:32We ain't wearing a coat.
47:33Unfortunately, they aren't wearing reasons.
47:34The Mama-Tibetite Forum isϋ brain movements.
47:35No, ничего doesn't mean to that.
47:36What if it is believed to be requested?
47:37Is it a lot overstock?
47:38I'm a lot overiging when we're drivingirus,
47:39Seven inandidature tunnel?
47:41Two hours away.
47:42And I don't remember 51 years ago
47:44I'm a few seconds,
47:47so late esperar is it's before we're talking.
47:48If it is an emperor,
47:49it's before we haveischen pea earrings.
47:50Yes, it's too far.
47:51It's too far.
47:52It's too far.
47:53It's too far.
47:54It's too far.
48:02Sudden snow has blocked the way.
48:04And it is not until midnight that all team members are back at base camp.
48:13With no time to take a rest, they must set off again immediately.
48:19Let's go.
