Developed by Thomas Newcomen, it would turn water into steam to run a water pump. The Newcomen pump used the same chamber for heating and cooling steam, and was slow and consumed lots of coal. It was expensive.Dagogo Altraid in his book New Thinking: From Einstein to Artificial Intelligence, the Science and Technology That Transformed Our World tells us that Mr Watt conceptualised an improvement during a Sunday afternoon walk in Glasgow. He proposed a separate chamber that would condense the steam. It would improve efficiency and reduce cost.Subsequently his steam-run piston connected to levers and cogs would move wheels in locomotives, ships and textile factories. James Watt took a walk, and the world changed forever -- the first industrial revolution was set in motion.About eighty years later the mass extraction, processing and commercial use of petroleum to fuel these engines began in the United States. The second industrial revolution was on its way. The availability of petroleum products helped develop the internal combustion engine, improving mobility on a far greater scale than steam power – later revolutionising the use of automobiles, ships and aircraft.Energy generated from coal, petroleum, diesel and gas thus industrialised the West, and became the prime mover of its socio-economic system, and subsequently spread to every country in the world which followed the same development path.Human beings had unprecedented mobility, the world achieved progress, but use of fossil fuels over the next two centuries and half accumulated carbon dioxide in the atmosphere increasing its concentration from less than 300 parts per million (ppm) in the pre-industrial era to 418 ppm today. This and other greenhouse gases trapped more heat and amplified anthropogenic climate change.In the early 19th century scientists were already examining the relation between the sun, earth and atmosphere. French physicist Joseph Fournier in the 1820s postulated that the Earth's atmosphere might face a ‘greenhouse effect’. British physicist John Tyndal later explored this idea further, and in 1859 demonstrated that a greenhouse effect would trap the sun’s reflected radiation in the earth’s atmosphere – increasing the average surface temperature of the planet.The First World Climate Conference organised by the World Meteorological Organisation in 1979 had formally identified increased atmospheric concentrations of greenhouse gases as the leading cause of global warming.

Heat waves and forest fires would be more devastating. In fact, the IPCC’s Assessment Report 6 (AR6) issued in August 2021 reported that from 2011-2020 the global surface temperature was already ~1.1oC higher than the baseline of 1850-1900.The Paris Accord of 2015 aimed to limit average temperature rise from 1.5 to 2 oC  warmer compared to pre-industrial levels to minimise the risk of <a href="http://archive.nepalitimes.com/article/editorial/climate-climax,3651" data-saferedirecturl="https://www.google.com/url?q=http://archive.nepalitimes.com/article/editorial/climate-climax,3651&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNGg1f7MjDygQNSsOoABK_DhRH9UBw">a planetary climate disaster</a>. Member countries agreed to work on Nationally Determined Contributions (NDCs) that would set their own targets for reducing greenhouse gas emissions by cutting coal and petroleum use.Even these pledges will not meet the 1.5 to 2oC Paris target, warned the United Nations Framework Convention on Climate Change (UNFCCC) in a synthesis report on NDCs. In fact, at the current rate of emission reduction, global average temperature is unlikely to be limited to 2oC increase by 2050. The report warned that national emission reductions pledged in the NDCs should increase by an additional 80% if the target is to be met.If the current level of emission continues, by 2100 the world will be at least 2.7oC warmer. Earlier, the IPCC had predicted that the 1.5o C threshold would actually be exceeded in 2040. Sadly, institutional barriers, path dependencies, lack of actions, and denying of climate change science in developed countries act as barriers to faster decarbonisation.For Nepal, as elsewhere in the world, the loss and damage from the climate emergency is already a part of daily life. <a href="https://www.nepalitimes.com/banner/first-drought-then-downpour/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/first-drought-then-downpour/&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNFpzE9obZKPOn8iozib-zgjtAvfKA">Droughts</a> leading to unprecedented <a href="https://www.nepalitimes.com/banner/wildfires-ravage-nepal-mountains/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/wildfires-ravage-nepal-mountains/&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNFAZV0Kauf850haiih8DYv_r_QDxQ">wildfires</a>, record-breaking rainfall, <a href="https://www.nepalitimes.com/banner/disasters-in-nepal-come-in-waves/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/disasters-in-nepal-come-in-waves/&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNG1DVkUqSSJ15kG7LZ_omJrvp0M0Q">extreme weather events</a>, <a href="https://www.nepalitimes.com/banner/on-thin-ice-in-the-khumbu/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/banner/on-thin-ice-in-the-khumbu/&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNGFcAtH18vGuvAx8RPbhAWSOV431Q">receding snowlines</a>, shrinking glaciers, and <a href="https://www.nepalitimes.com/opinion/nepals-silent-emergency-springs-going-dry/" data-saferedirecturl="https://www.google.com/url?q=https://www.nepalitimes.com/opinion/nepals-silent-emergency-springs-going-dry/&amp;source=gmail&amp;ust=1632793832912000&amp;usg=AFQjCNFsextCf2VRpjOw-ROgboe7cUZvKg">springs going dry.</a> In Glasgow, world leaders have to commit to drastic reductions in greenhouse gas emissions, and pledge help to countries like Nepal to cope with the climate crisis.It is indeed symbolic that the UN’ Climate Change summit (called COP26) in November is being held in Glasgow, the same city where James Watt took a walk during which he came up with the idea that made more efficient coal fired steam engine 258 years ago. Perhaps world leaders should also take a walk while in Glasgow to come up with an urgent plan to undo the planetary crisis unleashed by Watt’s steam engine.

The report acts as a stark reminder that inaction will exacerbate the climate-related impacts the world is already facing. It confirms that Earth’s temperature is higher now than it has ever been in the last 125,000 years.The world has already warmed on average by 1.1°C compared to pre-industrial times due to human induced climate change. Each of the last four decades has been successively warmer.

Source: IPCC</figcaption></figure>Unprecedented pace of glacier retreatThere is no doubt that mountainous regions are at the forefront of climate impacts:  for example, high intensity rain and mountain slope instability can wash out roads and bridges, thereby affecting access to rural areas, and rapid change in mountain snow will have far reaching effects on both upstream and downstream.The IPCC report confirms that the rate of ice sheet loss increased by a factor of four in the last three decades. Through their climate warming greenhouse gas emissions, humans are the main cause of the global retreat of glaciers. The current rate of ice sheet loss, with almost all of the world’s glaciers retreating synchronously since the 1950s, has been unprecedented in at least the last 2,000 years.The unprecedented pace of glacier retreat at the global scale is more alarming in the Himalayas. Two years ago, the <a href="https://www.icimod.org/landmark-study-two-degree-temperature-rise-could-melt-half-of-glaciers-in-hindu-kush-himalaya-region-destabilizing-asias-rivers/" data-saferedirecturl="https://www.google.com/url?q=https://www.icimod.org/landmark-study-two-degree-temperature-rise-could-melt-half-of-glaciers-in-hindu-kush-himalaya-region-destabilizing-asias-rivers/&amp;source=gmail&amp;ust=1628763074515000&amp;usg=AFQjCNGt4zvQzrZY-rYUYDPjdo6l7e_Lrg">Hindu Kush Himalaya Assessment</a> report by ICIMOD confirmed that even if global warming is limited to 1.5°C, temperatures will remain at least 0.3°C higher in the Hindu Kush Himalayas (HKH), and at least 0.7°C higher in the northwest Himalaya and Karakoram regions of Pakistan. As a consequence, 36% of the glaciers in the region will be gone by 2100. And this is the “best case” scenario where the world manages to limit warming to 1.5°C and avoid the worst impacts of climate change.Climate change is also intensifying the water cycle and affecting rainfall patterns. The IPCC report confirms that the intensity and frequency of hot extremes, including heat waves, and heavy precipitation, as well as agricultural and ecological droughts continue to increase as temperatures rise. For South Asia including Nepal, the average precipitation as well as heavy rainfall events are projected to increase. This will result in more flooding and landslide events. All this will have far reaching consequences across the region with water-dependent energy sectors and water-intensive agricultural systems.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141128/636cfca89c7e80680e0a0b9fjpeg.jpg" alt="" width="640" height="315"><figcaption>Projected global temperature rise under the intermediate, high and very high GHG emission scenarios considered. Source: IPCC</figcaption></figure>Highlands to Islands linkagesThe impacts of melting glaciers are not only limited to the mountainous regions. Rapid ice sheet melt could lead to catastrophic sea level rise even before the end of the century. As outlined in the IPCC report, the global mean sea level has already risen by 20 cm and will continue to do so for thousands of years.The IPCC report confirmed that combined ice sheet and glacier mass loss contributed to 42% of this global mean sea level rise from 2006 to 2018.The report states with greater certainty than previous reports that mountain and polar glaciers will continue melting for decades and centuries to come. Continued ice sheet loss will also release greenhouse gases into the atmosphere -- as temperature rises and permafrost thaws, it decomposes and emits carbon, further amplifying climate change that is causing it to melt.Rising temperatures could melt most mountain glaciers and add more to the sea level rise, both leading to the extinction of small islands and mountain habitats. This cycle that binds the highlands to the islands demonstrates the need for collaboration between mountainous and island countries in the international climate change discourse.  Such collaboration could help to amplify the voice of most vulnerable nations calling for the major emitters to take urgent actions to reduce emissions.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141128/636cfca99c7e80680e0a0ba0jpeg.jpg" alt="" width="640" height="546"><figcaption>Future annual emissions of CO₂ under the five scenarios SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5. Source: IPCC</figcaption></figure>Path to followThe IPCC report clearly shows the grave risks of exceeding 1.5°C above pre-industrial levels – an upper limit of warming which the global community has agreed to in the Paris Agreement. Yet, from the perspective of a mountainous country, even a 1.5°C temperature rise is too much, which will lead to one third of the Himalayan glaciers to disappear with devastating consequences for the region.All decisions from now on, therefore, must be guided by the fact that every extra tonne of carbon dioxide and other greenhouse gases will lead to more warming and any increase in warming will lead to devastating impacts on lives, livelihoods and ecosystems across the world.The most vulnerable countries, including mountainous areas, are already at the forefront of fatal climate and weather disruptions. These countries with limited resources will continuously require international support to combat climate change, and at a scale well beyond current levels. The IPCC report must act as a wakeup call for all governments, in particular the biggest polluters such as the G7 and G20. They must take urgent action in response to the climate emergency, starting by adopting robust and bold 2030 climate commitments by the next UN climate summit - the <a href="https://unfccc.int/process-and-meetings/conferences/glasgow-climate-change-conference" data-saferedirecturl="https://www.google.com/url?q=https://unfccc.int/process-and-meetings/conferences/glasgow-climate-change-conference&amp;source=gmail&amp;ust=1628763074515000&amp;usg=AFQjCNHXeAsyEsnaY7moQlGAVCE0LJc8zA">COP26</a> - in November.Manjeet Dhakal is Head of LDC Support Team at Climate Analytics and serves as an Advisor to the Chair of the Least Developed Countries Group at the multilateral process of the UNFCCC.

They also found that the thickness of the ice in the glaciers had also shrunk considerably.“Just in the past 60 years, the Gangapurna glacier has receded by more than 900m,” Sigdel said in an interview. “And the speed at which they are receding has accelerated.”[caption id="attachment_54098" align="alignleft" width="500"]<img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/2022110915110/636bb2c29c7e80680e07bb00jpeg.jpg" alt="" width="500" height="515"> Satellite imagery of the Gangapurna Glacier (top) and the Annapurna III Glacier in 1988, 2008 and 2019 showing that the rate of glacial retreat is accelerating.Indeed, the paper says that while the length of the Gangapurna Glacier reduced by 386m at 17.5m per year between 1957 to 1979, the speed picked up to 24m per year from 1979 to 2016 – receding by a full 903m in that time. The Annnapurna III Glacier receded at a slower pace and was smaller by 500m in the past 65 years due to the different gradient and size of the catchment.As the ice melted, vegetation started creeping up the mountains.

Forests replace glaciers in the Himalaya

The sudden and massive flood on the Bhote Kosi early Tuesday morning washed away a strategic bridge on Nepal’s main border crossing with China for trade, tourists and pilgrims. Slurry from the nearly 10m high debris flow left 9 dead and 20 missing, 12 of them Nepalis and six Chinese nationals, and 150 others were rescued by helicopter.&nbsp; Four <a href="https://nepalitimes.com/banner/climate-smarter-himalayan-infrastructure">hydropower plants</a> Rasuwagadi, Trisuli III, Trisuli, &nbsp;Benighat and the Trisuli substation sustained heavy damage, knocking &nbsp;out 230MW of Nepal’s power supply – approximately 8% of the total. Over 100 cargo trucks and new electric vehicles parked at &nbsp;Timure Dry Port were swept away.

However, the Department of Hydrology and Meteorology (DHM) and the National Disaster Risk Reduction and Management Authority (NDRRMA) now say a <a href="https://nepalitimes.com/here-now/living-below-nepal-s-melting-mountains">Glacial Lake Outburst Flood (GLOF)</a> is likely.&nbsp; NDRRMA spokesperson Suresh Sunar said it was too early to tell which one, but the flood was most likely the result of one of the glacial lakes in Tibet. Bhote Kosi begins on the north slope of the Ganesh Himal near the Nepal-China border, and its tributary Lende drains the catchment area north of Langtang. The slurry flood on Tuesday was on the Lende (map).&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250709110720_bbc99c5f3e3d61a3d340892e0273fee3605a8d334a2beb354126137bcf0c8d27.jpg" data-media-id="editor_3" data-image-id="20250709110720_bbc99c5f3e3d61a3d340892e0273fee3605a8d334a2beb354126137bcf0c8d27" data-rendition-name="original" width="629" height="759" loading="lazy" alt="Bhote Kosi flood map"> </figure>   <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250709110720_39e2f574ff8c12cecda2e5a999d2ba8a0310f599f6b2261dcad7dd43f94df2a1.jpg" data-media-id="editor_4" data-image-id="20250709110720_39e2f574ff8c12cecda2e5a999d2ba8a0310f599f6b2261dcad7dd43f94df2a1" data-rendition-name="original" width="997" height="613" loading="lazy" alt="Bhote Kosi flood map"> </figure>  “Preliminary study suggest that the disaster was not caused by rain in Tibet, but by a glacial lake burst, or another accident,” said Kamal Ram Joshi of the DHM.

The river meets the Bhote Kosi at the Nepal-China checkpoint in Rasuwa.&nbsp; “Analysis of weather forecasts and satellite data shows the Tibet region did not receive enough rain to cause this scale of flooding,” explained Binod Pokharel, associate professor of hydrology and meteorology at Tribhuvan University. “The flood could have been caused by a GLOF."&nbsp; Two weeks ago, Chinese officials had reportedly warned the Rasuwa District Administration in Nepal to be on high alert for floods on rivers that originate in Tibet.

Chinese Ambassador Chen Song and Prime Minister Oli visited the border on Tuesday (pictured). &nbsp; The sharing of real-time trans-boundary rainfall and river flow data would be crucial in early warning about the <a href="https://nepalitimes.com/news/mapping-kangchenjunga-glacial-flood-risk">risk and consequences of GLOFs</a> to reduce human and material loss. But Nepali officials say China has been reluctant to share weather-related information and data not just in this disaster, but in the past as well. “There is no mechanism or system in place for us to obtain hydrological and meteorological data of the Tibetan region,” said DHM Director General Joshi. The <a href="https://nepalitimes.com/here-now/for-destruction-ice-is-also-great-and-will-suffice">Himalaya is melting twice as fast as the rest of the world</a> due to a phenomenon called ‘elevation dependent warming’, and receding glaciers have led to an increasing number of transboundary GLOFs.&nbsp; According to <a href="https://nepalitimes.com/here-now/danger-nepal-s-glacial-lakes-are-filling-up">a 2018 ICIMOD study</a>, of the 47 of the most dangerous lakes that threaten Nepal, 25 are on glaciers in China, 21 in Nepal and one in India. Many of these glaciers are expanding rapidly due to global warming. One of the authors of the report, glacial lake expert Samjwal Bajracharya, says that the report was prepared based on data from 2015. But climate change has accelerated since then. Moreover, seismic activity has further destabilises the landscape, adding to <a href="https://nepalitimes.com/here-now/nepals-glacial-lakes-in-danger-of-bursting">GLOF risk</a>.&nbsp; “Considering the rapid rate of snowmelt and consequent increase in size of Himalayan glaciers, studies should be conducted every year, and a monitoring system should be set up on the glaciers,” says Bajracharya. “However, no studies have been conducted in the Himalaya in a decade, which has been our biggest weakness.” &nbsp;

Rasuwa flood likely a GLOF

Recent outrage in Sikkim over an Indian Army expedition climbing <a href="https://nepalitimes.com/here-now/saving-kangchenjunga">Kangchenjunga</a>, the world’s third-highest peak, has spiked attention to the need to balance mountaineering jobs with indigenous reverence for sacred landmarks. Kangchenjunga (8,586m) is not a peak as much as it is a mountain range with 16 peaks above 7,000m on the border between India and Nepal -- the word itself means ‘five treasures of the snows’ in Tibetan. Some of the highest prominences like Kangchenjunga West and Kangbachen are in Nepal, while the Main, Central and South Peaks are on the border. Climbing the peak from the Indian side has been banned since 2001 because the indigenous Lepcha community there regard the mountain as the abode of Dzoe-nga, the patron deity of Sikkim, which was an independent Himalayan Kingdom until it was annexed by India in 1975.&nbsp; Buddhists in Sikkim say their saint, Padmasambhava, recognised the mountain as a protective spirit. The state has declared the base of the mountain Kangchenjunga National Park, which covers an area one-third of Sikkim. ‘The act of scaling this sacred peak is not only a matter of serious concern but also a violation of both the prevailing legal provisions and the deeply held religious beliefs of the people of Sikkim,’ read a letter from Chief Minister Prem Singh Tamang (Golay) to Amit Shah, India’s Minister of Home Affairs and Cooperation.&nbsp; Tamang continued: ‘We further request Your Honour to take up the issue with the Government of Nepal to ensure that no future expeditions are permitted on the sacred mountain, in deference to the deeply held beliefs and cultural values of the people of Sikkim.’ Kangchenjunga was climbed for the first time exactly 70 years ago by a British team who told King Tashi Namgyal, the Choegyal of Sikkim, that they would not set foot on the summit. Since then, there have been about 532 successful climbs of the peaks and 52 have died while trying.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250628060616_5c268e08cf49f36b79ef9b31933fc2d9bf9a6f65414e7ca06dd028bf04e7ccc1.png" data-media-id="editor_1" data-image-id="20250628060616_5c268e08cf49f36b79ef9b31933fc2d9bf9a6f65414e7ca06dd028bf04e7ccc1" data-rendition-name="original" width="1782" height="1178" loading="lazy" alt="Kangchenjunga: too sacred to climb NT"> <figcaption>Indigenous communities in Sikkim held purification ceremonies following the Indian expedition to Kangchenjunga. Photo: THE VOICE OF SIKKIM / FACEBOOK</figcaption> </figure>  <a href="https://nepalitimes.com/here-now/peak-climbing-season-2025-s4abrxny">This spring climbing season</a> alone, there were 70 climbing permits for foreigners issued for Kangchenjunga by the Nepal government, and made it to the top while one French climber died.&nbsp; One of the expeditions this year was an Indian Army team led by Col Ranveer Jamwal, who has summited the highest peaks on all seven continents, and Mt Everest thrice. Jamwal’s team was on the final leg of a ‘<a href="https://economictimes.indiatimes.com/news/india/nimas-summits-mt-kangchenjunga-concludes-historic-har-shikhar-tiranga-mission-successfully/articleshow/121341315.cms?from=mdr">Har Shikhar Tiranga</a>’ (The Tricolour on Every Peak) mission to plant the Indian flag at the highest points of each of India’s 28 states. Kanchenjunga was the last peak they had left, and the hardest, but the expedition put five climbers on the summit. What seems to have incensed the Sikkimese is that while it has banned climbing the mountain from its side, it was an Indian military expedition that went to Nepal to climb the mountain. After news broke of the climb in May, the Sikkim Indigenous Lepcha Tribal Association asked people to observe purification ceremonies in temples across the state. Mayalmit Lepcha of the association acknowledged that the Sikkim government was also partly at fault: “I don’t think such an expedition could have gone forward without the state government being informed, so it could have done something to intervene. It shows weakness. What’s done is done, all we can do is carry out these sanctification ceremonies.”&nbsp; In 2000, one year before Sikkim’s ban, the state allowed an Austrian team to attempt Kanchenjunga’s northeast face for a fee of $20,000, on agreement that they would stop 10m before the summit. Despite this, there was outrage over the expedition on the grounds that it violated Indian laws regarding the defiling of religious sites and Sikkim’s rights to maintain its culture after merging with India. The Indian Army expedition was also seen to have circumvented Sikkim’s law and violated religious sensibilities by going through Nepal. While the team may have thought they were respecting Sikkim’s beliefs by finding a way to complete the mission, the people of Sikkim saw it as defilement.&nbsp; The somber mood of the Sikkim people at the ritual contrasts sharply with Jamwal’s sense of accomplishment. “Without a doubt, the most difficult summit of my life,” he told reporters after the climb. “It tested every ounce of our will.”&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250628060616_ccfe079c78dab788d19fe2080ee8a5d5dcb11de4157316f6d94e5964da097157.jpg" data-media-id="editor_4" data-image-id="20250628060616_ccfe079c78dab788d19fe2080ee8a5d5dcb11de4157316f6d94e5964da097157" data-rendition-name="original" width="787" height="377" loading="lazy" alt="Kangchenjunga: too sacred to climb NT"> <figcaption>Prayer flags along the Sikkim-Kangchenjunga trekking route. Photo: TREKKINGININDIA.COM</figcaption> </figure>  The <a href="https://nepalitimes.com/news/the-rise-and-fall-of-nims-purja">controversial Nepali-British mountaineer Nirmal Purja</a> was also on Kangchenjunga this spring the mountain, on a mission to summit all 14 8,000m peaks for a third time. He echoed Jamwal about the tough conditions: “The conditions above camp were extremely tough, with deep snow and challenging terrain—more crevasses than usual.” Nepal’s government has not said anything publicly, but it is unlikely that it will ban climbing on Kangchenjunga, since it is becoming popular with expeditions because of its technical challenges, and overcrowding on Mt Everest. Nepal does have bans in place for some of its mountains out of respect for local beliefs. <a href="https://nepalitimes.com/banner/to-open-machapuchre-for-mountaineering-or-not">Mt Machapuchre</a> (6,990m) the imposing pyramid that looms over Pokhara, for example, is seen as an icon of purity by the Gurung people and a symbol of Vishnu by the Hindu communities who live at its base. A strict climbing ban has been in place since 1957, when a British expedition led by Col Jimmy Roberts stopped 45m short of the summit – either because the last bit was too difficult or out of deference to local sentiments.&nbsp; Khumbila that stands above Namche Bazar is only 5,761m high, but like Kanchenjunga is considered the protector deity of the Sherpa people. Gauri Shankar on the Nepal-China border, called Chomo Tseringma by the local community, was off-limits between 1965 and 1979 due to its association with Lord Shiva and Gauri, his consort. Although expeditions are now allowed, there are not too many takers. In Tibet, climbing Mount Kailash is prohibited by the Chinese government because it revered by the Hindus, Buddhists and followers of the Bon faith. Even Mt Everest is regarded as sacred, and its Sherpa name is Chomolungma, Goddess Mother of the Earth.&nbsp; Economically, climbs on Kanchenjunga bring in decent revenue. This climbing season, the 41 permits, at $1,800 each, brought in $73,800. This is somewhat comparable to Makalu, Lhotse, and Annapurna I, but these numbers are dwarfed by the $4 million in <a href="https://nepalitimes.com/news/the-everest-industry">Everest permits</a>. Revenue from Kanchenjunga climbing permits is something Nepal could potentially forgo if necessary, but the expeditions also provide jobs to hundreds of high altitude guides, porters, base camp support staff and other logistical costs.&nbsp; As the third highest mountain in the world and the tallest in India, there will always be significant motivation to climb it from the Nepal side, especially as climbers are drawn by the technical climbing at high altitude.

Kangchenjunga: too sacred to climb?

The debate about who is less accountable to the public: politicians or bureaucrats is as old as Nepal’s democracy itself.
Some blame politicians for being beholden to the businessmen who finance their electoral campaigns, and are forced to return the favour with contracts and kickbacks when in power.&nbsp;
Others say it is civil servants who are neither civil nor servants, and know the inner workings of the system to exploit loopholes – they then teach ministers, MPs, mayors, or ward chairs which juicy projects can be squeezed. And everyone gets their share.
In reality, it is probably not a case of either, or. Both have their hands deep in the honey pot. Corruption is now such a given that yet another exposé in the mainstream press, like the latest visit-visa scam, does not raise eyebrows anymore.
We may have to edit Lord Acton’s famous quote to say that in Nepal we do not even need absolute power to corrupt absolutely. The ruling cartel has divvied up the spoils, so that no one ever faces charges. The three parties all know about the skeletons rattling in each other’s closets, and they cancel each other out.
Politicians and bureaucrats get all the blame for taking bribes, but what of the givers of bribes? In this crony capitalism, businesses invariably need political patrons in an elaborate <a href="https://nepalitimes.com/here-now/nepals-only-growth-industry-private-sector-corruption" target="_blank">national network of give-and-take</a>.
<a href="https://nepalitimes.com/here-now/nepals-only-growth-industry-private-sector-corruption" target="_blank">Politicians and businesses work hand-in-glove</a> so that conflict of interest in contracts, insider trading, cartelling, and non-performing assets of banks become the norm. Our survey after the 2017 local election showed that out of the 753 newly-elected local government chairs, <a href="https://nepalitimes.com/news/elected-contractors" target="_blank">nearly 300 were contractors</a> involved in sand-mining, quarrying, or transportation syndicates.
Nepal’s tycoons have discovered that instead of donating to election war chests of politicians, it is a much surer return on investment to spend the money to <a href="https://nepalitimes.com/news/the-business-of-politics-in-nepal" target="_blank">become legislators and politicians themselves</a>.
In democracies, there are checks and balances to control corruption when it becomes endemic. The Nepal Police and Central Bureau of Investigation (CBI) are supposed to do the detective work without political interference. The courts are required to be independent in dispensing justice and punishing crooks.
But the less said about the judiciary the better. A writ petition in the Supreme Court last week accused our sister magazine <a href="https://www.himalkhabar.com/" target="_blank">HimalKhabar</a> of contempt of court for two stories: one about how high courts have been overturning a majority of verdicts of district courts in cases of rape, and another about the Biratnagar High Court clearing a self-proclaimed holy man, Krishna Bahadur Giri, of rape despite police presenting physical evidence.
The doctrine of the separation of powers stipulates that it is when the other three pillars in a democracy are compromised that the role of the free press becomes even more vital. The world over, as soon as populist autocrats are elected to the executive, their first order of business is to co-opt the legislature and the judiciary. Then they buy off, intimidate, or neutralise the media with Strategic Lawsuits Against Public Participation (SLAPP).
Nepal’s officialdom seems to be taking midnight Zoom lessons from other despots on how to gag the media. Last month, popular talk show host Dil Bhushan Pathak was served an arrest warrant by the Kathmandu District Court for <a href="https://www.youtube.com/watch?v=-CntsnTrtG8" target="_blank">a YouTube explainer</a> about the alleged involvement of the son of Foreign Minister Arzu Deuba Rana in a reported purchase of Kathmandu’s Hilton Hotel.
The Lalitpur District Court ruled that Pathak could not be arrested without fair trial, but this week the Kathmandu District Court filed another case against the journalist based on a complaint by the Cyber Bureau, and put him on a fugitive list.&nbsp;
Without going into the veracity of Pathak’s explainer, it is deeply problematic that the Electronic Transaction Act has been invoked – proof that politicians are getting the courts and investigating agencies to make an example of a high profile journalist.&nbsp;
The intention is to silence media investigations into the fake refugee scandal in which the main partner in the ruling coalition is implicated, and in which one of its former home ministers was jailed last year.
The Kathmandu High Court has been mysteriously active in targeting journalists these days. <a href="https://bizmandu.com/" target="_blank">Bizmandu</a> and <a href="https://nepalkhabar.com/" target="_blank">Nepalkhabar</a> were served a notice last month <a href="https://nepalitimes.com/news/no-freedom-after-expression-y4inku06" target="_blank">to withdraw a story they did</a> on the Chair of the <a href="https://www.sebon.gov.np/" target="_blank">Security and Exchange Board of Nepal (SEBON</a>) Santosh Narayan Shrestha allegedly demanding kickbacks from hydropower investors.&nbsp;
Incredibly, the court even asked the two portals not to report on the subject anymore – a ruling so absurd that the Patan High Court overturned it a week later.&nbsp;
The allegations against Shrestha were made in a public meeting of the <a href="https://www.ippan.org.np/members/3060/bungal-hydro-ltd" target="_blank">Independent Power Producers Association of Nepal (IPPAN)</a>, and MPs demanded a <a href="https://myrepublica.nagariknetwork.com/news/parliament-demands-probe-into-sebon-chairman-over-alleged-commission-demand-40-32.html" target="_blank">Parliament inquiry</a> into the regulator. <a href="https://www.himalkhabar.com/144523/santosh-narayan-shrestha" target="_blank">HimalKhabar</a> reported this week that while Shrestha was reportedly demanding commissions from private investors for IPOs, he cleared primary share sales in Bajhang’s 10.75MW <a href="https://www.ippan.org.np/members/3060/bungal-hydro-ltd" target="_blank">Bungal Hydro</a> in which his family members have investments, company records show.
And then just on Monday, bureaucrats hoodwinked MPs by deleting references in a bill requiring a two-year ‘cooling off’ period under which retiring civil servants could be barred from holding constitutional positions for two years.
The contest for who is more corrupt: bureauacrats, politicians, or the private sector is on.

Similarly, India’s Council on Energy, Environment and Water (CEEW) noted that cities like Delhi, Chandigarh, Jaipur, and Lucknow have experienced a 6-9% rise in relative humidity in the last decade.&nbsp; It also states that <a href="https://www.reuters.com/sustainability/climate-energy/majority-indian-districts-face-high-heatwave-risk-study-shows-2025-05-20/#:~:text=%22About%2057%20per%20cent%20of,usual%20number%20of%20heatwave%20days.">60% of Indian districts</a>, home to three-quarters of the country’s 1.3 billion people face a high to very high risk from extreme heat, with rising night-time temperatures and humidity. The heat index is also called ‘<a href="https://nepalitimes.com/here-now/north-indian-heat-wave-hits-nepal">wet-bulb temperature</a>’ and is a measure of how hot the human body feels when humidity levels are also high — usually much hotter than the recorded temperature. For example, a wet-bulb temperature of 35°C is considered the maximum limit of heat and humidity that humans can handle, beyond which the body cannot cool by perspiration, leading to death. One indicator of increasing humidity is a rise in average minimum temperature, and Nepal recorded the highest figure since 1981 last year, with a peak of 15.8°C. Higher minimum temperature denotes warmer nights, which in turn is an indication of heat stress caused by increasing humidity, which in turn is a result of global warming. Aside from higher average temperatures worldwide this year, what makes heat and humidity more unbearable is that cities are always hotter than their surroundings. This is due to the <a href="https://nepalitimes.com/opinion/comment/preparing-for-kathmandu-s-heat-waves">urban heat island (UHI) effect</a> – for example the temperature inside Kathmandu’s Ring Road can be hotter by <a href="https://www.epa.gov/heatislands/what-are-heat-islands">up to 4°C during the daytime and by 1 to 3°C in the evening</a> compared to the outskirts. “Climate change is one reason for rising temperature, but there are other factors like increased heat in urban spaces due to concrete buildings and infrastructure, emissions from vehicles, industries, and home appliances,” explains urban planner Bhushan Tuladhar. He adds: “Much of this comes down to how we have developed our cities, not just our roads and buildings but also our water system, waste management, culture and customs as well as economy.” There is a feedback loop at work: as it gets hotter, more energy is used for fans, coolers, and air-conditioners which in turn add to the urban heat bubble. The way to reduce the UHI effect is to have more parks, tree-lined streets and water bodies to cool cities down.&nbsp; <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212095525002093">A recent study published in the journal Urban Climate</a> by Nepali researchers at the University of Massachusetts, Tribhuvan University, University of Groningen, etc showed that even within Kathmandu, urban forests cooled neighbourhoods by as much as 1.2°C while ponds reduced the temperature by up to 0.85°C compared to nearby houses.&nbsp;  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20250703090748_e4de75dbdfb5fcfdeb0935eda364dc16b5dca8857ba335ab0f4586ebdc5093a9.jpg" data-media-id="editor_8" data-image-id="20250703090748_e4de75dbdfb5fcfdeb0935eda364dc16b5dca8857ba335ab0f4586ebdc5093a9" data-rendition-name="original" width="2580" height="1038" loading="lazy" alt="urban heat island in Kathmandu"> <figcaption>Source: URBAN CLIMATE et al.</figcaption> </figure>  ‘Our results demonstrate that blue-green spaces provide significant cooling benefits across the Kathmandu Valley, with distinct patterns by type, size, design, and urban context,’ concluded the paper, whose lead author is Saurav Bhattarai at Jackson State University in the United States. The old towns in Kathmandu Valley with traditional brick and tile architecture, ponds and trees managed hot summers better. Compact houses around a courtyard gave people just the right amount of sunlight, and use of clay mortar and bricks insulated houses in winter while cooling them in summer. There were open spaces, fertile land along the floodplains for farming, and brick pavements that allowed for seepage. “Our cities were planned taking nature into account,” says Sangeeta Singh, a professor of urban planning at the Institute of Engineering. “Kathmandu Valley is now built up, but we can still reintegrate blue-blue spaces into town planning with vertical gardening, urban forestry, using local material and harvesting rainwater.”&nbsp; Kathmandu’s municipalities have by-laws controlling building design and structure, but strict enforcement of land use and zoning are missing. Extreme heat disproportionately affects the urban poor who may not have access to fans or air-conditioners, exacerbating poverty.&nbsp; Cities in the plains have it even worse. As heat and humidity rise simultaneously, it could <a href="https://nepalitimes.com/banner/garmi-se-behal-chalo-nepal">reverse the current mass migration</a> of people from the mountains to the Tarai, where 53% of Nepal’s population lives. <a href="https://thedocs.worldbank.org/en/doc/92fbbbc6180238e18e7b239fad83e38a-0280032024/original/12-DHNT-Temperature-poverty-inequality-September-2024.pdf">A World Bank study</a> put the cost of a 1°C rise in temperature at 17.1% increase in poverty globally. Estimates put the total number of urban poor in developing countries exposed to the worst heat extremes at 26 million presently, this number is bound to grow to 215 million by mid-century, an over eight-fold increase. Meanwhile, 489,000 health-related deaths occur each year, 45% of them in Asia alone. “Heat has to be seen from a class perspective,” says Singh. “Those with money can afford gadgets and appliances to keep their homes and offices cool, but not day labourers or poor families living in cramped housing with poor ventilation.” Climate breakdown is going to widen the class divide in cities, as <a href="https://nepalitimes.com/banner/unthinkable-in-the-current-climate">summers become unliveable</a>. Says Singh: “We need policy intervention to address this class injustice. Our building by-laws and new town development must urgently integrate climate and energy efficiency elements.”
