Vertical profile of precipitation in the Baltoro region, reconstructed from Decheng (1978) and Wake (1989). Due to the recession of mountain glaciers worldwide, the fraction of debris cover in the ablation zone is increasing almost everywhere (Reference Diolaiuti, DAgata and SmiragliaDiolaiuti and others, 2003a). The rapid disappearance of these glaciers has become a matter of great concern for Pakistans economy and the livelihoods of millions of people who depend on them for their daily needs. (a) The velocities along the longitudinal profile determined by repeated, short-term GPS measurements. Smiraglia, C. Table 1. The velocities on Godwin Austen Glacier are of similar magnitude (120 m a1). Distances measured from Desio boulder (3366 m a.s.l.) The main glacier extends over a distance of 62 km from Conway Saddle at 6200 m to the glacier snout close to Paiju at 3400m (Fig. One of the largest Karakoram glaciers, Biafo Glacier, flows south-east from the central Karakoram crest. Biafo Glacier - Wikipedia The strong annual velocity variations indicate that basal sliding plays a major part in the ice transport of Baltoro glacier. At least 16 such glacial lake outburst floods linked to heatwaves have occurred this year already, compared with an average of five or six per year, the Pakistani government said earlier this week. 3). Diolaiuti, Guglielmina The grain-size also shows a very large variation all over the glacier, from sub-millimetre dust to boulders of a few metres diameter. Glacial melt off has been affected due to climate change, increasing risks of flooding. This means abundant meltwater enhances ice flow and results in higher velocities than the mean annual velocities. Read about our approach to external linking. and Mihalcea, C. Buraschi, Elisa 20 important facts about the glaciers of Pakistan - Tourism Teacher By donating us $100, $50 or subscribe to Boosting $10/month we can get this article and others in front of tens of thousands of specially targeted readers. and The analysis of the gravity data is based on an elliptical glacier bed, which resulted in a cross-sectional area of the glacier of 3.86 0.7 km2 for that case. Kirkbride, M.P. For Concordia, there exists one of the famous panoramas of V. Sella from 1909. Fig. This means that for the relevant accumulation area of Baltoro glacier, which lies above 5300 m for the Godwin Austen region and 5500 m for the Baltoro south region (Reference WissmannWissmann, 1959), the mean annual precipitation is about 1600 mma1. Pakistan's melting glaciers are 'erupting' and worsening floods - CNN Surface profile at the Gore I cross-profile, measured with differential GPS. Godwin Austen (Reference Godwin AustenGodwin Austen, 1864); W. Conway (Reference ConwayConway, 1893)). The Himalayan glaciers are melting, and Pakistan is drowning Improved water management practices, including the development of water storage infrastructure, can help mitigate the impact of glacier melting and reduce the risk of floods and water scarcity. ), the Great Sauqdara (53.0 sq. Fig. With a mean slope of 3.9%, it is a rather flat glacier compared with other glaciers of the Karakoram Range. Diolaiuti, Guglielmina Encouraging joint research between India and Pakistan on climate change, glacier dynamics, and water management could help identify new solutions and promote collaboration between the two countries. Here, meltwater ponds, superficial streams and bare ice only account for a few per cent of the glacier area. In this way it is possible to estimate mass fluxes for different gates across the glacier. Lit. This equates to an annual velocity of 214 m a1 for the 3 days of observations. The most spectacular glaciers in the world are here. Because of this number, Pakistan is one of the most glaciated countries outside the polar regions. 6). In the past poorer countries with weaker flood defences or lower-quality housing have been less able to cope with extreme rainfall. Pakistan contributes less than 1% of the global greenhouse gases that warm our planet but its geography makes it extremely vulnerable to climate change. The very small values upstream of Gore I are measured very close to the glacier margin. UN Starts World's Biggest Glacier-Mapping Project in Pakistan Surveys in flood-hit nation to be completed in next 1.5 years Warmer climate has worsened melting at over 5,000 glaciers Passu. Diolaiuti, G. Huts submerged by heavy rain ahead of Cyclone Biparjoy's landfall are seen in a costal village in Shah Bandar, near Thatta, in Pakistan's southern Sindh province, June 15, 2023. The glacier as classified in this paper is shown in grey on the background of the shaded digital elevation model. and Kamp, Ulrich The surface velocity has been measured by differential GPS at 32 stakes distributed over the glacier from Urdukas up to about 4800 m. The base stations for the measurements have been placed on firm ground at the glacier margin (at Urdukas, Gore I and Concordia). Feature Flags: { Smiraglia, Claudio Shroder, , John F. However, the uncertainties are rather large (on the order of 35%), which could easily obscure an imbalance in the glacier mass balance. 7). A shepherd with his herd crossing DARALGAHAI pass, Swat valley.jpg. The triangles are proportional to the ice surface velocity and provide a qualitative impression of the velocity distribution over the glacier surface. Pakistan is a home of 108 peaks above 6000m, and numerous peaks above 5000 and 4000. At Biafo glacier, Reference WakeWake (1989) found the maximum precipitation values in the elevation range 49005400m. Lambrecht, Astrid Pakistan has 7,532 glaciers, more than . Read about our approach to external linking. Shrestha, Arun B. K2 - Italian camp.jpg. Due to lack of time, we could not reach the same elevation as Sella 95 years before. Get focused newsletters especially designed to be concise and easy to digest. The government has warned that 33 of these lakes, all located in the spectacular Himalaya, Hindu Kush and Karakoram mountain ranges that intersect in Pakistan, are at risk of bursting and releasing millions of cubic metres of water and debris in just a few hours, like in Hassanabad. Most of these glaciers are located in the northern part of the country and are breathtakingly beautiful. We promise, no spam! . Standing and stored crops have been destroyed and some two million acres (809,371 hectares) of farm land inundated. Baltoro Downstream.JPG. The resulting annual mean velocity at Concordia, therefore, is 95 20 m a1. The general melt period at Baltoro is shown as a black bar, and the intense melting period is indicated by a light grey bar. Has data issue: false The quantification of the debris thickness is even more difficult, due to the limited number of sample points and the large thickness variations even over short distances. Climatically this station is also influenced by the Indian monsoon system. A comparison with the estimated mass input from the upper part of the glacier shows excellent agreement. Close this message to accept cookies or find out how to manage your cookie settings. It is one of the few glaciers in the world that is still growing. and and and 2010. In recent years, Pakistan has experienced several. But rising global temperatures linked to climate change are causing the glaciers to rapidly. Mayer, C. And the country does have some flood defences but they could be improved, he says. For the upper Baltoro (upstream of Concordia), the mass balance is very likely close to zero. Surface velocities of the glacier based on differential GPS measurements and feature tracking of satellite images. 2008. Miar Glacier. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its head at Indira Col . The Famous Glaciers in Pakistan - Karakorum Expeditions Abruzzi Glacier The Abruzzi Glacier is a glacier north of the Baltoro Kangri peak in Gilgit-Baltistan, Pakistan.

Bishop, Michael P. Several studies have found that annual precipitation exhibits a very large vertical gradient. He says that Pakistan's meteorological service did a "reasonable" job in warning people in advance about flooding. Pollution and global warming are causing the glacier to melt and form unstable lakes that could burst their icy banks at any . Mayer, Christoph 2007. Along almost the entire glacier margin which is identifiable on the images, the ice is more or less at the same level as 95 years ago. So far, only the velocities from the GPS measurements have been discussed. The water also washed away two small hydro plants and a bridge that connected the remote community to the outside world. The theme highlights the need for global cooperation to address environmental challenges. and Apart from exploration teams and mountaineers, Baltoro glacier has received little attention in the way of glaciological investigations (Reference Dainelli and MarinelliDainelli and Marinelli, 1928; Reference SpoletoSpoleto, 1930; Reference Desio, Marussi and CaputoDesio and others, 1961; Reference DingDing, 1992). Photo: DFID UK Department for International Development/Flickr. [2] Almost all of them are located in the northern regions of Gilgit-Baltistan and Khyber Pakhtunkhwa . Overview of the Baltoro drainage basin and the location of Baltoro glacier in Pakistan. Phillippe, Jeff Hand-picked stories once a fortnight. The glacier joins the Baltoro Glacier (one of the largest glaciers outside the polar region) that flows northwest in the beginning and then turns westward. The vertical precipitation profile, the area/elevation distribution and the prevailing climatic conditions have been used to determine the net accumulation above the equilibrium line, which resulted in a mass flux of 0.51 km3 a1 for this part of the glacier. Smiraglia, Claudio From there the velocity drops again rather rapidly to 85 ma 1 at Urdukas. Boost this article Pakistan received nearly 190% more rain than its 30-year average from June to August - reaching a total of 390.7mm. Dr Saeed says the floods are "absolutely a wake-up call" to governments globally who promised to tackle climate change at successive UN climate conferences. The main recorded parameters are temperature, humidity, wind speed and radiation. The following is a list of glaciers in Pakistan: [1] With more than 7,253 known glaciers, Pakistan contains more glacial ice than any other country on Earth outside the polar regions. You might also like: Two-Thirds of Worlds Glaciers Set to Disappear by 2100 Under Current Global Warming Scenario: Study. Diolaiuti, Guglielmina The triangles are proportional to the ice surface velocity and provide a qualitative impression of the velocity distribution over the glacier surface. All stake positions shown have been measured twice with differential GPS. Cutler, Mark E. J. Pakistan's Sachin Glacier melting faster than other Himalayan glaciers The glacier reserves feed local livelihood systems and support unique ecosystems of global importance, in addition to serving as a source of water for downstream areas. India has made progress in promoting renewable energy but more needs to be done to reduce the countrys dependence on fossil fuels. Mihalcea, C. However, the bergschrund could be identified almost everywhere along the high-elevation basins. 9). It looks like you're using an ad blocker. We humbly apologize for the inconvenience. An analysis of the measurements carried out during the last 91 years shows that there is no clear trend of recession or advance. Some minor changes are discernible, but their magnitude is minor compared to changes of other mountain glaciers, especially in the Alps, where glaciers lost about 30% of their surface area in the same time-span (Reference BenistonBeniston, 2003). This means they can be used together for tracking stable features on the glacier. 6), the estimated net ablation for the specified area is 0.17 km3 a1. The glacier has an area of 2740 km2 and is about 60 kilometres long. "People have the right to be angry. How melting glaciers contributed to floods in Pakistan : NPR Render date: 2023-07-05T10:08:23.631Z Values above 6100 m are only estimates. "coreDisableSocialShare": false, The Batura Glacier is one of the largest glaciers in Pakistan and is located in the Gilgit-Baltistan region. How Pakistan floods are linked to climate change - BBC News Serie II: Risultati geologici e geografici. However, in an unpublished picture by A. Desio in 1929, the entire glacier snout looks almost identical to the modern one. 6. However, the Indian government has so far failed to take concrete measures to control pollution. Moreover, cooperation between India and Pakistan as well as support from the international community are key to the successful implementation of these measures. The reason for such limited changes on Baltoro is surely the debris cover present on its surface. The theme of this years G20 summit, which will be held in India in September, is One Earth, One Family, One Future. (b) The velocities of the cross-profiles based on the summer velocities from GPS measurements. 5). Comparison of the situation at Concordia in 1909 (V. Sella in Reference De FilippiDe Filippi, 1912, lower image) and 2004 (taken by C. Mayer, upper image). Failure to address this issue will not only harm Pakistans economy and water security but also have wider implications for the region and the world. Copland, Luke Fig. However, a combination of anthropogenic climate change and air pollution from neighbouring countries like India and China has significantly contributed to the rapid melting of these glaciers, causing devastating floods that have affected Pakistans economy. Implementing a. and other neighbouring countries could help reduce emissions and mitigate the impact of climate change on Pakistans glaciers. The various measurement positions on Baltoro glacier. Fig. Bae Seong, Yeong And we have had resulting glacial melt. Interpolating these values onto the longitudinal GPS profile (GPS) of Figure 7a results in the lower velocity profile (FT). The melting of glaciers is also causing an increase in natural disasters such as floods and landslides. Raising public awareness about the impact of melting glaciers in Pakistan and the urgent need for action can help build support for policy measures aimed at addressing the issue. From the comparison of historical measurements and photographs it is shown that the snout of Baltoro glacier is oscillating back and forth a couple of hundred metres. View all Google Scholar citations "corePageComponentUseShareaholicInsteadOfAddThis": true, 7. Thickness measurements at more than 60 locations have been carried out, which show large variations even within small areas. To enjoy our content, please include The Japan Times on your ad-blocker's list of approved sites. Lambrecht, Astrid Photo: Wikimedia Commons. Cutler, M.E.J. Addressing the issue of melting glaciers in Pakistan requires international cooperation and collective action. Ice-free areas and ice-covered areas which are not directly connected to the main glacier system provide mass through avalanches or wind redistribution. Classification map of the Baltoro drainage basin. As Baltoro glacier is a debris-covered glacier, ice ablation also depends on the debris properties. In some of the depressions, major meltwater streams drain the surface of the glacier (R). 2011. Mainz, Abh. By subscribing, you can . The town of Karimabad, Pakistan, is nestled near the Ultar glacier. This field is for validation purposes and should be left unchanged. Pakistan is home to the worlds second-largest mountain range, the Karakoram, which contains the largest concentration of glaciers outside the polar region. One can cause high temperatures and drought, like the heatwave in March, and the other brings monsoon rains. Although percentage contribution of glaciers here is lowest among other HKH ranges, . As the world warms, glacial ice is melting. The adverse effects of glacier melting on Pakistans economy highlight how pollution caused by neighbouring countries like India and China has contributed significantly to this issue. The glacier as classified in this paper is shown in grey on the background of the shaded digital elevation model. The contributions of the several tributary glaciers to the main Baltoro glacier are shown. Considering all the points mentioned above, balance calculations have been carried out for the part of Baltoro glacier upstream of Concordia. During this 50 year time-span, the glacier tongue has receded about 200 m and the snout has become flatter. Pakistan is home to more than 7,000 glaciers, more than anywhere else on Earth outside the poles. Landsat and ASTER have an optical resolution of the same order of magnitude. Pakistan is the most glaciated country on the planet but faces increasing water scarcity due to the vulnerability of its primary water source, the Indus River, to changes in climate and demand. Thus, we have a long history of glacier photography. Companies are still extracting fossil fuels from Balochistan, but people there have just lost their homes and have no food or shelter," he says. (a) The velocities along the longitudinal profile determined by repeated, short-term GPS measurements. According to a study published in the Journal of Geophysical Research: Atmospheres, up to 80% of the black carbon deposited on the glaciers in the Karakoram comes from outside the region. Glacier melt constitutes over one-third of the Indus River's discharge, but the impacts of glacier shrinkage from anthropogenic climate change are not equal across all eleven subbasins of the Upper Indus. In the region of Liligo and up to a few kilometres upstream of Gore I, individual ice sails can clearly be identified on the otherwise debris-covered glacier. A comparison of these short-term measurements during the melt season with surface velocities computed from feature tracking of satellite images shows a high seasonal variability of the ice motion. Net accumulation then reduces linearly to 0% of the precipitation value at the equilibrium line. As dawn breaks over Javed Rahis mountain village, a loud boom shatters the silence and a torrent of water comes cascading down from the melting glacier nearby, followed by a thick cloud of smoke. Ahmad, N. The theme highlights the need for global cooperation to address environmental challenges. The Intergovernmental Panel on Climate Change (IPCC) estimates that the glaciers in the Himalayas could shrink by two-thirds by 2100, which would have . Result of the feature-tracking analysis of the central part of the ablation zone. As a result, the government, has been diligently working to combat air pollution in the country. An analysis of the ASTER images from 2001 has shown that the flowband of these two glaciers together still represents 60% of the glacier width at Urdukas and 40% close to the glacier snout. The distance is given from the northern margin of the glacier. Pellicciotti, Francesca reaching a total of . KAMP: So a glacier is a larger mass of ice that is moving along a slope. Typically these firn basins are 58 km long, roughly 10% of the entire glacier length. At Gore I, an extensive stake network has been installed for detailed investigation of the ablation conditions in the debris zone (Reference Mihalcea, Mayer, Diolaiuti, Lambrecht, Smiraglia and TartariMihalcea and others, 2006). Global warming is making air and sea temperatures rise, leading to more evaporation. As mentioned above, the cross-section at Concordia is a natural location for the computation of mass fluxes. The Famous Glaciers in Pakistan - Karakorum Expeditions At some stakes, thermistors at different depths in the debris cover recorded the temperature at a sampling interval of 5 min. But international cooperation, including support for adaptation measures and funding for research and development of new technologies to reduce greenhouse gas emissions, is equally essential. Similar conditions exist at Urdukas, whereas the other profiles are too short for an analysis of the transverse velocity gradient. Projects Glaciers and Students Glaciers and Students The northern parts of Pakistan are home to some of the vast stretches of glaciers after the northern pole. Bishop, M. The very small values upstream of Gore I are measured very close to the glacier margin. and Special attention was given to the ice ablation in the debris-covered areas of the glacier (Reference Mihalcea, Mayer, Diolaiuti, Lambrecht, Smiraglia and TartariMihalcea and others, 2006). According to a report by the Centre for Research on Energy and Clean Air, India is the worlds largest emitter of anthropogenic sulphur dioxide, which is a significant contributor to air pollution, and its cities, Encouraging sustainable development practices, including the use of renewable energy, water conservation, and. hasContentIssue false. . There, the ice velocity is still 70% of the centre velocity. Our two measurements have been selected according to the azimuth values of earlier observations. This year, record-breaking glacial melt washed the discharge measuring station clean away. (b) The velocities of the cross-profiles based on the summer velocities from GPS measurements. Variations of the lower part of Baltoro are now, and will also be in the future, most probably due to the reaction of the tributary glaciers to changes in climate. Olsenholler, Jeffrey A. We also express sincere thanks to A. Tamburini, L. Bonetti and G. Peretti for assisting the fieldwork, and E. Vuillermoz for support in automatic weather station management and meteorological data processing. In some of the depressions, major meltwater streams drain the surface of the glacier (R). According to Fifth Assessment Report IPCC. According to a study published in the, Journal of Geophysical Research: Atmospheres. As a result, the government has been diligently working to combat air pollution in the country. for this article. Clendon, Penelope The terminus variations collected since the beginning of the 20th century confirm the glacier snout behaviour demonstrated by the photo comparison. Would you spend the night in a coffin for art? However, in this region the rather active Trango glacier enters Baltoro glacier, which could result in higher ice velocities in this frontal part. Fig. Importance of glaciers for water availability in Pakistan An exact calculation of debris cover is rather difficult, but the analysis of the available satellite images enabled a statistical evaluation of the glacier surface conditions. Reducing emissions from Indias energy and transportation sectors could help mitigate the impact of climate change and reduce the melting of glaciers in Pakistan. "All of this is happening when the world has warmed by 1.2C - any more warming than that is a death sentence for many people in Pakistan," he adds. Fig. For the conversion it was assumed that for elevations with degree-day sums of 0, net accumulation equals 100% of precipitation (for Baltoro glacier this is the case above 5700 m, using extrapolated temperature data from Srinagar; Fig. The theme of this years G20 summit, which will be held in India in September, is One Earth, One Family, One Future. Tamburini, Andrea In spite of the surge-type behaviour of neighbouring glaciers (Reference Diolaiuti, Pecci and SmiragliaDiolaiuti and others, 2003b) and a worldwide recession of alpine glaciers (Reference BenistonBeniston, 2003), this glacier seems to be protected by its extensive debris cover, which reaches almost up to the accumulation area. 1). The range contains total of 1,103 glaciers contributing 21 % to the total glaciers of the HKH region. One obvious location for the investigation of mass fluxes is the transect just downstream of the confluence of Baltoro south and Godwin Austen glaciers at Concordia. The science linking climate change and more intense monsoons is quite simple. Smiraglia, Claudio Fieldwork for these investigations has kindly been enabled by the Ev-K2-CNR project Scientific and Technological Research in Himalaya and Karakorum in the framework of the scientificmountaineering expedition K2 2004 50 years later. According to the latest studies, glaciers are retreating and increasing the occurrence of glacier-related hazards and also increasing sea levels. The field data have been supplemented by remote-sensing imagery, allowing us to extrapolate the point information on the glacier surface. 2011. Climate-resilient infrastructure, such as flood protection measures and drought-resistant crops, can help reduce the impact of climate change on the countrys economy and water security. According to a, It comes as no surprise that China has been plagued by poor air quality since becoming the worlds factory, as its extensive production and factory operations have led to significant pollution that has had a major impact on the quality of life of Chinese citizens. Run-off of meltwater from these high-elevation regions is restricted to very few days during the summer months and affects only a few per cent of the total accumulation. However, this effect has been taken into account via a simple degree-day approach in the calculation of the net accumulation. The main locations and glaciers are shown on the map. A Study of Glaciers in Northern Pakistan - ResearchGate Black carbon and other pollutants from these two countries are also significantly contributing to the melting of Himalayan glaciers. 2). Smiraglia, Claudio Smiraglia, Claudio Every year, as the weather warms, teams of Indian scientists trek the Himalayan mountains to study the Chhota Shigri glacier in Indias northern state of Himachal Pradesh. Comparison of the situation at Concordia in 1909 (V. Sella in De Filippi, 1912, lower image) and 2004 (taken by C. Mayer, upper image). Pakistan is home to more than 7,000 glaciers, more than anywhere else on Earth outside the poles. The many glaciers in this region, particularly those of the Karakoram Range, are among the few in the world to have grown in size since the late 20th century.
