1 00:00:01,920 --> 00:00:06,760 Speaker 1: Welcome to brain Stuff production of iHeart Radio, Hey brain 2 00:00:06,800 --> 00:00:11,160 Speaker 1: Stuff Lauren Bogobam here. Discussions about climate change tend to 3 00:00:11,200 --> 00:00:15,240 Speaker 1: focus on low lying areas like coastal cities, yet people 4 00:00:15,280 --> 00:00:18,400 Speaker 1: who live at higher elevations also feel its negative effects, 5 00:00:18,600 --> 00:00:22,560 Speaker 1: including fresh water shortages. To help these folks get by, 6 00:00:22,840 --> 00:00:26,240 Speaker 1: a Ladaki inventor named Sonam Juan Chuk has created a 7 00:00:26,280 --> 00:00:31,080 Speaker 1: line of artificial glaciers called ice Stupas. They're restoring frozen 8 00:00:31,120 --> 00:00:33,400 Speaker 1: water so it can be used to hydrate crops in 9 00:00:33,440 --> 00:00:37,040 Speaker 1: the driest stretch of the year. Glacial melt water is 10 00:00:37,040 --> 00:00:40,600 Speaker 1: a necessity for most villages in Ladak, a region of 11 00:00:40,640 --> 00:00:43,879 Speaker 1: northern India. Ladak sits on the Tibetan Plateau between the 12 00:00:43,920 --> 00:00:48,519 Speaker 1: Caricorum and the Himalayan mountain ranges. This elevated terrain is 13 00:00:48,560 --> 00:00:52,320 Speaker 1: world famous for its ice supply. Tibetan Plateau and surrounding 14 00:00:52,360 --> 00:00:55,600 Speaker 1: mountains contain more ice than any other non polar area 15 00:00:55,720 --> 00:00:58,600 Speaker 1: on Earth. Much of this is stored up in glaciers, 16 00:00:58,720 --> 00:01:01,200 Speaker 1: which helped feed vital Asian waterways like the Young z 17 00:01:01,640 --> 00:01:06,839 Speaker 1: the Mekong and Indus Rivers. Unfortunately, those glaciers are receding 18 00:01:06,920 --> 00:01:11,120 Speaker 1: because of climate change between two thousand three and the 19 00:01:11,160 --> 00:01:14,520 Speaker 1: ones located near the Brahmaputroz River source lost six point 20 00:01:14,600 --> 00:01:18,119 Speaker 1: nine billion cubic miles of ice. That's twenty eight point 21 00:01:18,120 --> 00:01:23,759 Speaker 1: eight billion cubic kilometers. With glaciers, some seasonal melting is expected, 22 00:01:24,120 --> 00:01:27,639 Speaker 1: but normally winter snowfall allows glaciers to replace the melted 23 00:01:27,680 --> 00:01:31,559 Speaker 1: ice they lose during the springtime. However, across the plateau, 24 00:01:31,680 --> 00:01:35,200 Speaker 1: glaciers are no longer getting enough annual snowfall to offset 25 00:01:35,280 --> 00:01:38,400 Speaker 1: their lost water, and so many of them have been 26 00:01:38,440 --> 00:01:43,080 Speaker 1: dwindling in size. As a cold desert lagac area sees 27 00:01:43,200 --> 00:01:45,840 Speaker 1: very little ratefall, receiving an average of just two to 28 00:01:45,920 --> 00:01:48,920 Speaker 1: three inches per year that's about fifty to seventy millimeters. 29 00:01:49,400 --> 00:01:51,600 Speaker 1: The summer months of June through August do get a 30 00:01:51,640 --> 00:01:55,040 Speaker 1: modest amount of precipitation, However, that's also when a large 31 00:01:55,080 --> 00:01:58,240 Speaker 1: quantity of melted water from neighboring mountain glaciers enters the 32 00:01:58,240 --> 00:02:01,960 Speaker 1: streams that La Duck depends on. A steady water flow 33 00:02:02,000 --> 00:02:05,440 Speaker 1: fills the streams during the winter as well. Yet, because 34 00:02:05,480 --> 00:02:08,440 Speaker 1: of the frozen ground and low air temperatures, the farmers 35 00:02:08,440 --> 00:02:10,679 Speaker 1: can't grow crops during the coldest months of the year. 36 00:02:11,480 --> 00:02:14,520 Speaker 1: According to wang Chuk, winter water gets under utilized. As 37 00:02:14,560 --> 00:02:18,760 Speaker 1: a result, demand for milt water grows exponentially in April 38 00:02:18,760 --> 00:02:21,840 Speaker 1: and May, when the life sustaining crops of wheat, buckwheat, 39 00:02:21,919 --> 00:02:25,360 Speaker 1: and barley need to be sown and hydrated. But in 40 00:02:25,400 --> 00:02:28,400 Speaker 1: the springtime, before the glacial water arrives in force, the 41 00:02:28,440 --> 00:02:33,520 Speaker 1: streams often run dry. Climate change has worsened the problem. 42 00:02:33,520 --> 00:02:36,600 Speaker 1: A twenty seventeen study found that over the past six decades, 43 00:02:36,800 --> 00:02:39,600 Speaker 1: about twenty percent of the permanent ice preserves in Ladock's 44 00:02:39,639 --> 00:02:43,359 Speaker 1: home state have disappeared. That translates to less milt water 45 00:02:43,440 --> 00:02:47,440 Speaker 1: for the locals. Hoping to solve these water woes, a 46 00:02:47,520 --> 00:02:50,240 Speaker 1: civil engineer by the name of Chiwang north Fell devised 47 00:02:50,280 --> 00:02:52,959 Speaker 1: an innovative reservoir system in the nineteen eighties, and I 48 00:02:53,080 --> 00:02:55,680 Speaker 1: hope I'm saying his name correctly. I couldn't find a pronunciation. 49 00:02:56,440 --> 00:03:00,000 Speaker 1: Using dams and channels, nor Fell diverted large volumes of 50 00:03:00,000 --> 00:03:02,640 Speaker 1: glacial water into man made lakes on the shady sides 51 00:03:02,639 --> 00:03:06,200 Speaker 1: of mountains, where it froze into blocks. Come springtime, the 52 00:03:06,240 --> 00:03:08,320 Speaker 1: ice would melt and be sent downhill to farms and 53 00:03:08,440 --> 00:03:12,160 Speaker 1: villages by way of canal, but this ice melted too quickly, 54 00:03:12,360 --> 00:03:14,519 Speaker 1: so the water tended to run out before the summer 55 00:03:14,560 --> 00:03:19,840 Speaker 1: rains arrived. Wang Chuk deduced that the ice in Norfell's 56 00:03:19,919 --> 00:03:22,280 Speaker 1: dams melted so fast because too much of it was 57 00:03:22,280 --> 00:03:25,200 Speaker 1: exposed to direct sunlight. When Chuke figured that if he 58 00:03:25,240 --> 00:03:28,080 Speaker 1: could somehow freeze the ice into a conical tower with 59 00:03:28,160 --> 00:03:31,640 Speaker 1: the narrow end aimed skyward, much less surface area would 60 00:03:31,639 --> 00:03:36,360 Speaker 1: be exposed. To make his frozen stalagmites, wang Chuk devised 61 00:03:36,360 --> 00:03:40,040 Speaker 1: an irrigation system that's brilliant in its simplicity. The major 62 00:03:40,080 --> 00:03:43,320 Speaker 1: component is a long pipeline. Most of this is buried 63 00:03:43,360 --> 00:03:46,480 Speaker 1: deep underground, with one end tapping into a glacial stream 64 00:03:46,560 --> 00:03:50,880 Speaker 1: or naturally occurring reservoir high in the mountains. Through the tube, 65 00:03:51,040 --> 00:03:53,720 Speaker 1: the water rushes in the direction of populated areas at 66 00:03:53,760 --> 00:03:58,200 Speaker 1: lower altitudes. No moving parts or electrical gizmos are needed 67 00:03:58,240 --> 00:04:01,040 Speaker 1: to keep the liquid water flowing. Gravity does the trick. 68 00:04:01,600 --> 00:04:04,120 Speaker 1: It also pushes the water into the final stage of 69 00:04:04,120 --> 00:04:08,320 Speaker 1: its journey downhill. The pipeline connects at a sharp angle 70 00:04:08,400 --> 00:04:11,200 Speaker 1: to another narrower pipe that rises out of the soil, 71 00:04:11,640 --> 00:04:15,600 Speaker 1: standing vertically like a telephone pole. As the saying goes 72 00:04:15,840 --> 00:04:20,120 Speaker 1: water seeks its own level. Gravity and pressure gained by 73 00:04:20,200 --> 00:04:24,040 Speaker 1: flow through the narrowing pipe together naturally propel the liquids 74 00:04:24,040 --> 00:04:26,440 Speaker 1: straight up that pipe until it flies out of a 75 00:04:26,440 --> 00:04:29,680 Speaker 1: sprinkler on the pipes raised tip high in the air, 76 00:04:29,960 --> 00:04:33,480 Speaker 1: the spray encounters atmospheric temperatures in the ballpark of negative 77 00:04:33,520 --> 00:04:36,800 Speaker 1: four degrees fahrenheit that's about negative twenty celsius or lower. 78 00:04:37,320 --> 00:04:40,919 Speaker 1: Before landing, it freezes solid, forming a large cone of 79 00:04:40,960 --> 00:04:45,240 Speaker 1: ice around the vertical pipe. The cone's distinctive shape resembles 80 00:04:45,279 --> 00:04:48,160 Speaker 1: that of a stupa, which are traditional Buddhist prayer monuments 81 00:04:48,200 --> 00:04:51,680 Speaker 1: that have graced Ladoc four thousands of years. Hence, whine 82 00:04:51,760 --> 00:04:54,000 Speaker 1: Chuk and his associates have taken to calling the new 83 00:04:54,040 --> 00:04:58,920 Speaker 1: glacier like structures ice stupas. Laduc's ice stupas melt down 84 00:04:58,920 --> 00:05:01,520 Speaker 1: in late spring, right when the need for liquid water 85 00:05:01,680 --> 00:05:06,479 Speaker 1: is greatest. The prototypical stupa, erected in the winter, contained 86 00:05:06,480 --> 00:05:09,000 Speaker 1: about forty thousand gallons that's about a hundred and fifty 87 00:05:09,000 --> 00:05:11,880 Speaker 1: thousand liters of frozen water, and lasted until May eight. 88 00:05:14,480 --> 00:05:18,400 Speaker 1: Since then, numerous others have been constructed. A single stupa 89 00:05:18,440 --> 00:05:21,560 Speaker 1: has watered as many as five thousand newly planted trees. 90 00:05:22,120 --> 00:05:25,240 Speaker 1: Standing at sixty feet that's eighteen meters tall, it held 91 00:05:25,279 --> 00:05:28,480 Speaker 1: a breathtaking five hundred and thirty thousand gallons that's two 92 00:05:28,520 --> 00:05:32,320 Speaker 1: million liters of frozen water. Others may someday exceed a 93 00:05:32,400 --> 00:05:35,000 Speaker 1: hundred feet about thirty meters in height and hold two 94 00:05:35,040 --> 00:05:38,200 Speaker 1: point six million gallons or ten million liters of water. 95 00:05:39,760 --> 00:05:43,240 Speaker 1: Outside of India, the stupas have spread to countries like Switzerland. 96 00:05:43,520 --> 00:05:46,560 Speaker 1: In twenty sixteen, win Chuk's Icy Brainchild earned him a 97 00:05:46,600 --> 00:05:50,839 Speaker 1: coveted Rollings Award for Enterprise. But ice stupas are not 98 00:05:50,920 --> 00:05:54,080 Speaker 1: without their critics. Win chuk in companies legal right to 99 00:05:54,120 --> 00:05:56,520 Speaker 1: divert glacial melt water has been challenged by a group 100 00:05:56,520 --> 00:06:00,200 Speaker 1: of La Ducky villagers. Furthermore, although the stupas are meant 101 00:06:00,200 --> 00:06:03,000 Speaker 1: to help sustain human life, they won't reverse the Tibetan 102 00:06:03,000 --> 00:06:07,599 Speaker 1: Plateau's worrisome climate trends. But if Homo sapiens is to 103 00:06:07,600 --> 00:06:10,440 Speaker 1: survive on a changing planet, will need to reevaluate the 104 00:06:10,440 --> 00:06:13,560 Speaker 1: ways we use and store water. Projects like this can 105 00:06:13,640 --> 00:06:21,920 Speaker 1: kick start those conversations.
