Mount Everest, the most familiar peak to people. Mountaineers regard climbing Everest as a glory of self-conquest, while scientists call it the "Third Pole" of the world, which, like the North and South Poles, is an important geographical landmark in our Earth's home, attracting numerous scientists to explore its secrets.

00:00Today, two wildlife researchers come to Mount Chomelangma base camp, looking for special visitors.
00:24They are Zhonghua from Beijing's Forestry University and Zala Sangpou from the Chomelangma National Nature Reserve.
00:35On nearby mountain slopes, they have installed seven infrared cameras.
00:40Now, they want to see what footage has been captured.
00:45There are a lot of photos, and there are a lot of photos, and there are a lot of photos.
00:54Let's take a look at the other photos.
00:57You should see the other photos.
00:59You should see the photos.
01:02They hope to capture images of elusive snow leopards within a kilometer of the base camp.
01:25While this may sound fanciful, villagers in the vicinity have indeed reported
01:31seeing snow leopards nearby over the past two years.
01:34If the sightings have been real, it means that a national effort to protect this rare feline species has been bearing fruit.
01:46For the best picture of all, Zhonghua decides to try his luck and point one camera directly at Mount Chumulungma,
01:53hoping to capture footage of snow leopards with the big mountain as the backdrop.
02:01Global warming in this mountain region could well boost populations of the animals snow leopards prey on,
02:09increasing their numbers as a result.
02:12But as snow leopards live near the snow line, which will rise because of global warming,
02:17they could also face a shrinking habitat.
02:21It's not possible to predict what the overall outcome will be.
02:25On May 1st, 2021, after filming the first stage of the expedition,
02:55undertaken by the Chumulungma Glacier Research Team of the Chinese Academy of Sciences,
03:01the documentary film crew travels from base camp to the source region of the Yarlang-Zangbo River,
03:07more than 800 kilometers away.
03:10Their purpose is to film two scientists studying the impact of climate change on the region's water resources.
03:17Liu Xiaochong is a well-known expert in using remote sensing to explore the origins of rivers.
03:26Nevertheless, he always prefers a field investigation over studying satellite maps in his office,
03:32even when it involves an arduous journey.
03:35To date, he has made field expeditions to explore and chart the source regions
03:40of more than 20 major rivers around the world.
03:46In 2008, he led a scientific expedition team to explore the origins of the Yellow River,
03:52Yangtze River, and Lansong River,
03:54and came up with new ideas on the sources of the three rivers.
03:58His partner in the survey was a geologist called Liu Tianji.
04:07Today, Liu Xiaochong and Liu Tianji are again working together
04:12to explore the source area of the Yarlang-Zangbo River,
04:15filmed by the same crew that recorded their survey of the three rivers' source area.
04:20Thirteen years have passed since their earlier cooperation.
04:29So, what changes have there been on the Qinghai-Tibet Plateau?
04:35The Yarlang-Zangbo River originates from glaciers at the west end of the Himalayas.
04:41Thereafter, it flows from west to east,
04:46across the range's northern foothills,
04:48until it reaches the eastern end of the range,
04:51and then flows southward.
04:57Although the Yarlang-Zangbo River never meets the Rongbuk River,
05:02which originates from the northern slope of Mount Chomalangma,
05:05the two flow through the same high-altitude area.
05:08So, the survey will include both rivers.
05:25Today, the team is hiking to a possible source of the Yarlang-Zangbo,
05:29the Ang Si Glacier.
05:34Soon after they enter their glacial valley,
05:36the altitude rises to 5,000 meters.
05:40With the terrain around covered in snow,
05:43there are hidden dangers on the ground underneath,
05:46so every step requires care.
05:48The Ang Si Glacier is not as stunning as the Rongbuk Glacier on Mount Chomalangma,
06:06and certainly less well-known.
06:08This is Liu Shaochong's third trip here,
06:14and he wants to find out if the glacier is,
06:17among sources of the Yarlang-Zangbo River,
06:19the furthest from its estuary in the dry, cold season.
06:24He subscribes to the principle that states,
06:26the origin of a river is that of furthest distance with unbroken flow.
06:31No matter which glacier is identified,
06:36as the source of the Yarlang-Zangbo River,
06:39glaciers are melting as the earth's sky.
06:41as the climate gets warmer.
06:43As a result,
06:43the precise coordinates of the origin
06:46of the Yarlang-Zangbo River are the source of the Yarlang-Zangbo River.
06:48The water is the source of the Yarlang-Zangbo River,
06:51and the water is the source of the Yarlang-Zangbo River.
06:59No matter which glacier is identified,
07:01as the source of the Yarlang-Zangbo River,
07:04glaciers are melting as the earth's climate gets warmer.
07:08As a result,
07:09the precise coordinates of the origins of many rivers are changing, too.
07:38After that,
07:38the rivers of the rivers of the Yarlang-Zangbo River
07:42have caused a disaster.
07:45Within the scope of the survey, therefore,
07:48how the impact of climate change on glaciers
07:51affects the changes in the Yarlang-Zangbo source
07:54will be a related topic.
08:08After three hours of tough hiking,
08:24the team finally arrives at a moraine-damned lake
08:27below the Yarlang-Zang glacier.
08:30at a moraine-damned lake below the Angxi glacier.
08:35A moraine-damned lake occurs when a moraine,
08:38or mass of rocks and sediment deposited by a glacier,
08:41prevents meltwater from leaving a valley.
09:00The expanding lake surface shows that climate change is accelerating the melting of glaciers.
09:13After investigation and evidence collection, everyone in the team is exhausted.
09:19Some even have to crawl on the way back.
09:23To everyone's surprise, Liu Tianji, the eldest team member, is the most composed.
09:29He even has the strength to organize everyone to record moments from the expedition on their cell phones.
09:51Leaving the Angxi glacier and heading north,
09:54the team arrives at the foot of the sacred mountain, Mount Kangrenbok.
09:59This is close to the sacred lakes Manasaravar and Rakshastal.
10:04Lake Manasaravar is the second largest freshwater lake in China in terms of volume.
10:10It is revered by locals.
10:16Lake Rakshastal, by contrast, is a saltwater lake.
10:20It is sometimes called the demon lake because of strange phenomena happening there.
10:27Lake Manasaravar is the germ stakeholders.
10:28Lake Aegis�� and
10:30Lake Borgesia program.
10:31Lake Tanavar is the largest fleetry Minsk exactly according to Almanya at bank.
10:32Lake Hanavar is the largest gem in glueлюд
10:54explorer Sven Hodin. In his book, My Life as an Explorer, Sven Hodin wrote about his 1907
11:02expedition. The waves mounted higher and higher, and the kayak rose and fell with the tide like a
11:09walnut shell. Hodin went out on Lake Manasarovar because he wanted to measure its depth. He also
11:17made an exploration of the waterway linking the two lakes.
11:24More than a century ago, in fact, the climate of the western part of the Himalayas became
11:50warmer and drier. Lake Manasarovar is close to the origins of three major Asian rivers,
11:59the Indus, the Ganges, and the Yarlang Zhangbo. After starting in the area, they gather water
12:05and flow in different directions, bringing sustenance to more than one billion people
12:11before they reach the sea. As the world's highest major river, the upper reaches of the Yarlang Zhangbo
12:19River have a dry, cold climate. This region, dominated by alpine grasslands, is only suitable
12:26for grazing. By the river's middle reaches, however, it has dropped significantly in altitude. A
12:33multitude of tributaries make for an abundance of water, which is used for irrigation. So this
12:39area has a dense population and is the most affluent in Xizang. The Himalayas with Mount Chomalangma
12:48as its main peak acts as a barrier to block warm and humid air from the Indian Ocean reaching
12:55the Tibetan Plateau. The waterways of southern Xizang, therefore, are fed mainly with meltwater
13:01from glaciers.
13:02Thank you so much for your feedback kazoo!
13:03Thanks, man!
13:03My answer is so happy that this…
13:04relevant state ofท sinn
13:22If enough snowfall can accumulate and form new glacial ice as glaciers melt, then they will be in balance, and there will be no danger of Shizong's rivers running dry.
13:49The crucial question is, after warm and humid air from the Indian Ocean rises to cross the Himalayas at altitudes of over 5,000 metres, how much snow can it bring to glaciers that are melting faster?
14:06It is this issue that Kong Shi Chong, a glacier expert at the Chinese Academy of Sciences, and his research team are most concerned about.
14:19The Mount Chomalongma Glacier Research Team are now hiking up the East Rongbuk Glacier, some 3,000 metres away from their camp, to take samples.
14:33Here, on the vast ice cap, high-altitude sunlight reflected by the snow can burn the skin in minutes.
14:54With a lack of oxygen bringing on quick fatigue, the team members must take turns in digging.
15:16Even talking can make them tired.
15:18KBS –
15:21KBS –
15:23KBS –
15:26KBS –
15:44So we're here.
15:46So, just for some of the standard methods,
15:51they're basically in the area.
16:07While here, the team will extract a sample of snow
16:10accumulated over the past few years,
16:12rather than an ice core.
16:42The snow pit Chen Pengfei mentions is similar to the pits
16:47that archaeologists dig,
16:49revealing different layers of soil from different ages.
16:52In the same way, different layers exposed by the team's snow pit
16:57are made up of snow that has fallen at different times,
17:00which are easy for the survey team to sample.
17:03In the same way, the liner is really low.
17:04In the same way, they're going to be able to move on to the
17:06survey team to sample.
17:07This is the main feature of the water on the ground.
17:19There is a lot of water in the ground.
17:22There is a lot of water in the ground.
17:26The water is in the summer.
17:30It is a lot of water in the afternoon.
17:34There is a lot of water, but it is still very硬.
17:38This is called a lot of water.
17:41This is a lot of water.
17:49The water is in the same year,
17:52or in the same year.
17:54We are not sure.
17:56It may be that this water is in the same year.
17:59There was a lot of water.
18:02After that, we covered it.
18:04It is also possible.
18:07We are only going to go to the experiment.
18:10We use the liquid-like liquid and liquid-like liquid.
18:13We can do a few minutes of water.
18:15We can do a few minutes of water.
18:17For example, from the last year,
18:20from the summer, and from the summer,
18:22and from the summer, and now.
18:24We can do a few years.
18:25We need to do a few minutes.
18:27We can do a few minutes.
18:32Scientists have observed that the annual precipitation on Mount Chou Malangma has not actually decreased.
18:42So a consensus has been reached among the scientific community that the rising temperature is the only reason for the past few decades' massive retreat of the Rongbuk glacier.
19:02In fact, we can see that the rainfall of the river is higher than the water, so the water is higher than the water.
19:09We can see that the rainfall of the river is still rising.
19:18How can we arrest global warming, or at least slow its rate?
19:24By analyzing snow samples from Mount Chou Malangma,
19:28Chinese scientists are also trying to figure out how much human activities, separate from natural processes, are affecting climate change,
19:37so as to better analyze all the reasons for accelerated glacier retreat.
19:42It is now an established fact that snowfall in the Mount Chou Malangma region is not enough to compensate for the retreat of Rongbuk glacier,
19:52a shortfall indeed exists across the whole Himalayan region.
19:57It is now an established fact that snowfall in the Mount Chou Malangma region is not enough to compensate for the retreat of Rongbuk glacier,
20:05a shortfall indeed exists across the whole Himalayan region.
20:12Some scientists have made the bold proposal of cutting canyons into the range to allow warm air from the Indian Ocean through.
20:20If this were successful, the Qinghai-Tibet Plateau might no longer need to rely on glaciers to maintain its ecosystem vitality.
20:30Such a huge project would of course be impractical, although clues exist to what its end result might look like.
20:39Canyons have indeed formed in the Himalayas because of geological plate movement from east to west.
20:52These valleys let in warm and humid air from the Indian Ocean, giving rise to areas of forest in the Himalayan range,
21:01one of which can be found in the National Nature Reserve at the foot of Mount Chou Malangma.
21:06It covers an area of more than 30,000 square kilometers with a vertical drop of over 6,000 meters,
21:21making it home to a full range of different ecological zones.
21:27The sea-traveling in a straight line, no more than 100 kilometers to the west of Mount Chou Malangma,
21:40also developed a very good energy supply chain.
21:49Traveling in a straight line no more than 100 kilometers
21:53to the west of Mount Cho-Mulangma,
21:55there is a port town called Zhangmu.
21:58The small town is flanked by mountains
22:00with a vertical drop of more than 4,000 meters.
22:04Its center is located at the bottom of Zhangmu Valley.
22:08Here, the climate is subtropical, meaning mild and humid.
22:13At dusk, you can often see Hanuman monkeys and Assam macaques
22:18wandering and confronting each other in the town.
22:23They are both primate species under first class and second
22:27class national protection, respectively.
22:31Given that the lush environment is suitable for both animals,
22:35it is no surprise that they often fight
22:37to protect their territory.
22:55Lying at an elevation of less than 3,000 meters,
22:58the Rongxia Valley, which is closer to Mount Cho-Mulangma,
23:02is also a temperate subtropical zone.
23:13In May, during their breeding season, Himalayan monals,
23:16the colorful pheasants native to Himalayan forests,
23:19will eat continuously to maintain their vitality.
23:24Compared with female monals, the male ones are more splendid.
23:28They possess a distinctive iridescent metallic-colored plumage
23:35and a bluish-green crest.
23:38It is estimated that there are less than 1,000 Himalayan monals in China.
23:47Lucky visitors may also come across the Himalayan tar,
23:50a species of wild goat native to the Cho-Mulangma National Nature Reserve.
23:55It is even rarer than the Himalayan monals.
24:00Only around 500 are left in China.
24:04By contrast, the blue sheep is very well adapted to high altitudes.
24:12Zoologists have captured images of these animals near the Mount Cho-Mulangma base camp,
24:17which lies at an elevation of 5,300 meters,
24:21in the transition area between alpine meadow and alpine desert zones.
24:28Blue sheep themselves attract snow leopards.
24:32In the Himalayas, blue sheep are their favorite food.
24:35In May 2021, Zhonghua and Zala Sangpou come to collect video surveillance footage
24:56from cameras near the Mount Cho-Mulangma base camp.
24:58Seven cameras have been filming here continuously for almost a year.
25:06Very often, they will get nothing, let alone the apex predator that is their ultimate goal.
25:13Although blue sheep are quite common in this region,
25:16snow leopards are sensitive and suspicious, and especially wary of humans.
25:21Perhaps this place is not far enough from trekkers.
25:24Perhaps the cameras have not been positioned at the right angle or height.
25:48For a while, it's looking like the luck is out.
25:51The surprise, however, comes when they review footage taken by their fourth camera.
26:08These are the very animals they dreamed of filming.
26:11On July 30, 2020, a mating pair adult snow leopards were caught by one of their infrared surveillance cameras.
26:24Afterwards, the cats appeared regularly near the base camp.
26:28The most interesting footage of all was taken on February 6, 2021, when a female snow leopard appeared,
26:46along with three healthy and lively cubs.
26:50When the birds were thrown out, it was a record of the batsmen.
26:55From the birds with a sun, it was a long-to-doodle protection.
26:56They areandois and wolves at a whole.
26:57Oh yes, yes.
26:58It was the best of the batsmen.
27:03It was a rarecylistic.
27:06Now, we were looking at the birds with these animals.
27:08And this is only the birds with a bandit.
27:09The birds with a bandit.
27:10When they looked at the stars, they wereOOOOOF.
27:12And they looked at the birds with some birds,
27:14they would fit in theirquitoes,
27:17Every one of them is not the same.
27:19You can compare them to each one of them.
27:22Then you can see that there are a few different ones.
27:25Yes.
27:26This area is 5,300 meters.
27:30Let's record a point.
27:35Okay.
27:36The three cubs in the footage are very curious.
27:50They lick and play with the camera every time they approach it.
28:06The footage means their home is not far from the base camp.
28:15Their last visit was only seven days before collection of the footage.
28:25The efforts of Zhonghua and Zala Sangpo have finally paid off.
28:30More than anything else, what they would like to see
28:33is the Snow Leopard family will flourish in the Mt. Chou Malangma area.
28:38Maybe the same family captured on video will show up again.
28:42.
28:43.
28:48.
28:50.
28:52.
28:53.
28:54.
28:55.
28:56.
28:57.
28:58.
28:59.
29:24.
29:26.
29:33With global warming in mind, researchers in the Chou Malangma National Nature Reserve
29:38persistently monitor the activities of the full range of wildlife there,
29:43from insects to beasts.
29:45.
29:46.
29:52.
29:54.
29:55.
29:56.
29:57.
29:58.
29:59.
30:00.
30:04.
30:05.
30:06River flows eastward from north of Mount Chomelangma
30:09and finally arrives at a narrow zone,
30:12below 3,000 metres above sea level
30:15in the eastern section of the Himalayas.
30:19Here, deep in the Igong Sengpo River Valley,
30:22a 300-hectare tea plantation lies hidden.
30:28It's the highest tea plantation in China.
30:31Nurtured by the gorge's favourable microclimate,
30:34the tea bricks produced here are known far and wide
30:38as Igong golden bricks.
30:43The landscape near the plantation is beautiful,
30:46but boulders and dead wood in the river stand as a warning.
30:50On a terrible evening in April 2000, a 5,500 metre high slope
31:07opposite the tea plantation suddenly collapsed,
31:11leaving a deposit of rubble in the valley bigger than any single building in the world.
31:15It completely blocked the river's course.
31:20Within two months, the volume of dammed water reached some 200 times that of the West Lake in Hangzhou.
31:24Rescue workers rushed to deal with the emergency, but the landslide dam was too large and finally burst.
31:43A 50 to 60 metre high wall of water then rushed down the valley, destroying almost all roads and bridges in its path.
32:06Although there was enough time to evacuate people living downstream,
32:15the well-known National Highway 318 remained disrupted for several months.
32:21The massive landslide had been triggered by glacial meltwater and was thus related to global warming.
32:27Not far from the Igong tea plantation at the eastern end of the Himalayas,
32:36there is a landmark snow-capped mountain.
32:39It is the magical Namcha Barwa Peak,
32:44at the foot of which the Yarlang-Zhangbo River makes an abrupt U-turn known as the Great Bend,
32:50before coursing and roaring its way to the south.
32:57The deep canyon housing the river makes it possible for warm and humid air from the Indian Ocean to flow in from the south.
33:05Mietok County in Xizhong Autonomous Region is located here.
33:12Before spring of 2021, visitors coming to it had to cross the Ga Long La Pass at elevation of about 4,000 metres above sea level.
33:22The pass is closed for eight months each year because of heavy snow.
33:27Even when it's open, cars are only allowed to drive in one direction.
33:32Snowflakes flutter in the wind, indicating both moisture and altitude.
33:39After crossing the pass and descending, however, the snow suddenly disappears.
33:44Instead, a sea of towering trees comes into view.
33:49Among them are brightly coloured rhododendrons.
33:53The increase in humidity encountered during the descent is very palpable.
33:58Now, the climate is subtropical, warm and humid enough to grow hardy bananas.
34:05Mietok was China's last county without a highway.
34:10Now, it takes four hours to drive to Mietok from Bomi County, 116 kilometres away, but over 2,500 metres lower in altitude.
34:21Along the way, the climate changes from winter to spring and then to summer.
34:28Zhang Lin is an ecologist at the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences.
34:44He travels to Mietok very often throughout the year.
34:47Today, he and his fellow researchers are visiting a rainforest there.
34:52We thought this place was a forestry forestry, but it has a forestry forestry.
34:58So, some people felt it is a forestry forestry.
35:01Look, you see, you can look at some places rather empty.
35:07It's because there is a forestry forestry.
35:09Yes.
35:10It's not something that big of a swimming pool.
35:13Right, you're quite right.
35:15Like this place, we can see the jettles, right?
35:19There are a lot of jettles,
35:20but there are not only one of the jettles.
35:21This is jettles.
35:24This is the famous jettles.
35:27Yes.
35:28This is too good for the heat of the jettles.
35:30How do we have the heat of the jettles?
35:34In the usual situation,
35:37we all think that between 21 degrees or 10 degrees,
35:40like in the Gulf, 19 degrees,
35:42we can see the heat of the jettles.
35:43We even think that even this way,
35:45it is also hot in the Gulf.
35:47So it's very unique to the jettles.
35:52The region between the two tropics,
35:54which lie at 23.5 degrees north
35:57and 23.5 degrees south of the equator,
36:00is the simplest definition for the Earth's tropical areas.
36:04Mertok, however, is located within the eastern Himalayas
36:08at a latitude of about 29 degrees north.
36:11How can tropical plant species flourish here?
36:14Mertok, how can tropical plant species flourish here?
36:17Mertok, how can tropical plant species flourish here?
36:20Mertok, how could tropical plants be coming to this distance?
36:25Mertok, how do we go to the region?
36:26Mertok can not wait to see the sun it's warm in the distance.
36:28It's very challenging to fill the air.
36:30Chen Xuelong works at the Institute of Tibetan Plateau Research of the Chinese Academy of
36:45Sciences.
36:47To research the climate of Motok, he is setting up a weather station in Guilin village in
36:52Motok County's southwest.
36:54The lushness of the tea fields shows the climate here is representative.
37:16Looking far north from the tea plantation, the high Namcha Barwa Peak can be seen towering
37:22over the Yarlang-Zengbo River.
37:25Pushed up the valley, a sea of clouds fed by the Indian monsoon is continuously shifting
37:31shape.
37:35Although he has not finished installing his weather station, Chen Xuelong has cleared targets
37:40for monitoring.
38:02Blocked by the lofty Himalayas, warm and humid air moving north is divided into two branches,
38:08like a flowing river.
38:11One branch flows westward and penetrates northwards at the opening of each canyon along its way.
38:20The other flows eastwards and finally finds a wide passage at the easternmost end of the
38:25Himalayas.
38:28This is the Yarlang-Zengbo Grand Canyon.
38:33To the west of Motok County is the eastern section of the Himalayan range, which runs in a southwest
38:40to northeast direction.
38:42To the east of the Himalayas lie the Hongduan mountains, which run north-south.
38:48The Yarlang-Zengbo River has cut a deep canyon between two mountains here, the lowest point
38:53of which is only 200 meters above sea level.
38:57As the channel becomes narrower, warm and humid air from the Indian Ocean is compressed and accumulates
39:10more heat and water vapour than that of other areas at the same latitude.
39:17This is why Motok has the tropical landscape with the highest latitude in the world.
39:33Not far from Motok County seat, the Yarlang-Zengbo makes another turn at Duxing Township, known
39:44as the Guo Guo Tong Great Bend.
39:47The mountain slopes here are also covered by neat tea plantations.
39:52Nowadays, tea has become one of the most important economic crops in Motok.
39:57In future, when better roads make for easier freight, Motok tea may also become a major brand
40:04of Xizang, just like Yigong tea.
40:07After passing Motok County, the warm and humid air pushes on into the northern Himalayas, giving
40:37eyes to landscapes of temperate climate as the altitude increases.
40:44At this elevation, fields are awash with pink and yellow flowers.
40:50The attractive scenery has made the area a popular tourist destination.
40:58These are Ningqi peach blossoms.
41:02Together with snow-capped mountains as their backdrop, and crystal clear rivers flanking them,
41:07they are a picture of breathtaking beauty.
41:10Ningqi is often called a small Jiangnan in Xizang, in reference to the picturesque scenery
41:18of the Yangtze Delta region.
41:28The big question now is, how are all of these different climactic zones, brought about by warm,
41:35humid air from the Indian Ocean, being funneled into the Yarlang Zhangbo Valley, being impacted
41:41by global warming?
42:02When the research team from the Chinese Academy of Sciences returns to the Institute in Lanzhou,
42:08Captain Chen Pengfei uses different instruments to study and analyze the soil and snow samples
42:15the team has gathered.
42:16One of the tasks of the Chomalangma Glacier Research Team has been to investigate the impact of industrial pollutants
42:23on the mountains' glaciers on the mountains' glaciers.
42:38One of the tasks of the Chomalangma Glacier Research Team has been to investigate the impact
42:43of industrial pollutants on the mountains' glaciers.
42:50The instruments can measure the quantity of such pollutants, including heavy metals, anions
42:55and cations, and mercury.
42:58Among pollutants, carbon-based substances have attracted the most attention from glacier experts,
43:04because they may be accelerating the glacier's melting.
43:11It is now a global consensus that the only way to avert a future climate disaster is to dramatically
43:40reduce greenhouse gas emissions.
43:45Since the Industrial Revolution, human activity has caused these to rise exponentially.
43:53Carbon dioxide in particular absorbs sunlight that has been reflected back by the Earth's surface,
43:59causing its atmosphere to gradually warm up like a greenhouse.
44:04Even on the upper slopes of Mount Chomalangma, which ascend to the highest point on Earth,
44:09atmospheric circulation brings in all kinds of pollutants to accelerate the melting of glaciers,
44:15and once they have settled, serve as markers for the atmosphere's changing composition.
44:21Mount Chomalangma is therefore a good place for scientists to gather samples,
44:26to analyze the dynamic of carbon emissions.
44:36Zhonghua has thrown himself into studies since returning from his trip to Mount Chomalangma.
44:41All the while, however, he has also been thinking of snow leopards on the mountain.
44:47One day, he is swiping his phone and suddenly comes across a video of snow leopards encountered
44:54on the foothills of Mount Chomalangma.
44:56One, one, two, three, four.
45:04Four snow leopards.
45:06Might they, by any chance, happen to be the same family captured with Zhonghua's infrared camera?
45:12It's possible.
45:13It's possible.
45:14It's possible.
45:15It's possible.
45:16It's possible.
45:17It's possible.
45:18It's possible.
45:19It's possible.
45:20It's possible.
45:21Now, we're going back to make a comparison with Hongai's infrared camera,
45:22and make a comparison with this.
45:23Let's see if it's a snow leopards.
45:28Zhonghua goes through the footage together with another researcher.
45:32They compare the snow leopards in the two videos again and again.
45:37To their excitement, it's the same family.
45:40We had to accommodate four leaf cubets.
45:42We've got a map on the golden 자연.
45:46We bridge both this couple of steps.
45:49We found out one of the left left on the left left side.
45:52This is edgy for both males and the right aiming for theenda machine.
45:57We can have one model camera on the thirdful light of this to the male female.
46:01We can decide it's a range from one rumah.
46:03Yes, the artist is 8mm.
46:07The spots on a leopard are like human fingerprints.
46:15They are unique and remain unchanged throughout its life.
46:29Zhuanghua tracks down and then contacts Thutok,
46:32who is the deputy director of the Rongbuk Monastery Management Committee
46:36and the man who shot the cell phone video.
46:40The place and time that the video was shot is further evidence
46:44that the four snow leopards in it are the same ones captured by Zhuanghua's camera.
46:49Less than a month has passed since the snow leopards were captured in the earlier footage.
46:55In the later video, it's obvious the cubs have grown up.
46:58The snow leopards are in the water.
47:01Wow.
47:03They're going to attack me.
47:07Some trees where they are.
47:09Zhuanghai Truong's even Graphos
47:12就是海拔最高的自然保護區
47:14除了 Sh translators,
47:15還有4座8000米以上的高峰
47:19分布在喜馬拉雅山這個區
47:22而且它的生物狀況性特別豐富
47:24是全球23個生物狀況性熱點分布區之一
47:28同時
47:29它也是列入人與生物圈計劃的自然保護區
47:34Mount Chomalangma rose with the Himalayas tens of millions of years ago.
47:52Today, it is a global landmark, a unique symbol for our home planet.
47:58It has inspired generation after generation of explorers
48:02and excited a spirit of self-challenging among humans.
48:19We must complete the test of the top of the top of the top.
48:23We have full confidence.
48:26The top of the top of the top of the top of the top of the top.
48:29The top of the top of the top is the top of the top of the top.
48:32Lofty snow-capped peaks, glaciers, rivers, seas of clouds, unique and abundant biodiversity.
49:00Mount Chomalangma, the top of the world,
49:04towers over the other giants in the Himalayas,
49:07providing an inspiration for the whole of humankind.
