A warming atmosphere also warms perennially frozen mountains. The stability of frozen rocks decreases with increasing temperature similar to how butter just taken out of a fridge &nbsp;becomes softer and less resistant to &nbsp;the cutting force of the knife. Thawing frozen mountains means softening them, making them less resistant against gravity, leading to breakage of small to large sections, resulting in rock falls, rock avalanches, and landslides. There is growing concern about <a href="https://nepalitimes.com/here-now/for-destruction-ice-is-also-great-and-will-suffice">the impact of global warming</a> on the stability of icy peaks in mountain ranges around the world, which several recent events in the Himalaya well illustrate. Permafrost is a technical short form of ‘permanent frost’ for frozen ground which remains at temperatures below zero degrees throughout the year.&nbsp; Permafrost is below the surface, is not directly visible, and therefore often escapes the attention of scientists and political authorities. Sophisticated methods must be used to explore it, such as drilling, geophysical soundings, or climate-related modelling.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_bbe43b730a10b861f318285a1999a1f6f4d245287618ff49ebfc8e51d154f573.jpg" data-media-id="editor_1" data-image-id="20240907160944_bbe43b730a10b861f318285a1999a1f6f4d245287618ff49ebfc8e51d154f573" data-rendition-name="original" width="4108" height="1000" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Even small glacial lakes, such as these currently forming near the terminus of the Kangchenjunga glacier in eastern Nepal, can be dangerous.

Polewards to around 60°N and S latitude, mean annual air and ground temperatures are mostly below 0°C. Permafrost is widespread in Alaska, northern Canada and Siberia. The lower limit of negative mean annual temperatures is at &nbsp;2,000-3,000m at mid-latitudes such as the <a href="https://nepalitimes.com/here-now/in-high-places">European Alps</a> or the Southern Alps of New Zealand, to 3,000-4,000m in the Himalaya, and to 5,000m near the equator in the Peruvian Cordilleras. Above these elevations, permafrost affects peaks. In high mountains the permafrost area is often far larger than their glacier-covered regions. In Nepal, the permafrost-affected area is about 2 to 3 times bigger than the glacier area, while in China with the perennially frozen Tibetan Plateau this factor is about 30. Temperatures decrease by 6-7°C for every 1,000m of altitude increase, and the coldest and most deeply frozen rocks are found in the highest parts of the peaks. The frozen zone inside mountains can reach depths of hundreds of metres. It is not just the ice on peaks in the European Alps or the Himalaya that is frozen throughout the year, but so are the rocks.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_b75f78e4ee6d146e797f06536491c445891fbeb578f60105f57247a8dc066bbd.jpg" data-media-id="editor_3" data-image-id="20240907160944_b75f78e4ee6d146e797f06536491c445891fbeb578f60105f57247a8dc066bbd" data-rendition-name="original" width="916" height="674" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Mt Chamlang (7,319m) with creeping frozen debris (rock glaciers, yellow arrows) and Lakes 464 and 465 (blue arrows) from glacier retreat at its foot.

Temperatures are not constant throughout the year, so a thin surface layer up to a few metres on top of permafrost that thaws in summer and freezes in winter. This seasonal freezing and thawing surface layer on permafrost is called the ‘active layer’. Deep, long-term freezing influences geomorphic processes inside mountains, drastically changing their properties. Growth of ice in cracks and fissures within solid rock tends to expand already existing openings, and even create new ones. The related weakening of bedrock, however, is compensated by strong adhesion and increasing strength induced by the ice fillings and related cold temperatures.

Perhaps most important is the effect of freezing and ice filling of cracks between rocks containing water. Deep frozen rocks are essentially impermeable to water as an often-decisive factor of stability inside mountain slopes. In the abundant debris masses at the foot of high mountains, deep, long-term freezing causes even more spectacular changes. Formation of ice inside and beyond the pores can create a mixture of ice and debris with ice lenses, enabling such ice-rich frozen masses to slowly creep down the slopes of mountains. Landforms resulting from permafrost creep over past millennia look like lava streams and are called ‘rock glaciers’.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_dc86dc2e254de22afefcd3f6c2df76af6c0aab87555f702dc853992987dcb3fc.jpg" data-media-id="editor_5" data-image-id="20240907160944_dc86dc2e254de22afefcd3f6c2df76af6c0aab87555f702dc853992987dcb3fc" data-rendition-name="original" width="1072" height="625" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> </figure>  Thawing out From long-term temperature measurements in deep boreholes, we know that global temperature increase of the atmosphere during the past about 100-150 years has warmed up mountain slopes down to depths below the surface of about 100m. The effect of this deep warming is the reversal of the freezing and cooling effects. It reduces the strength of rocks or debris with ice and makes them ‘softer’ and more permeable to water. Over the past decades, creep rates of frozen debris in rock glaciers have markedly increased, and the frequency of large rock-ice avalanches from high-mountain permafrost has accelerated. In the Peruvian Andes, two major events from mountain permafrost occurred in 2020 and 2023. Both had volumes of 1-1.5 million m3, reached lakes at the foot of the slope, and produced flood waves. The 2020 Salkantay flood caused loss of lives and heavy damage at Santa Teresa, 35km down valley. The flood wave at Rasac was fortunately retained within the lake at lower altitude. On 5 May 2012, a massive rock, ice, and debris avalanche from Annapurna IV <a href="https://nepalitimes.com/here-now/remembering-the-seti-disaster">cascaded into the Seti River gorge</a>, plummeting into a rockfall-dammed lake. The impact triggered an air blast that levelled thousands of hectares of forests, a dust cloud covered the countryside in fine white rock powder, and a hyper-concentrated slurry flood that killed 72 people downstream.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_81860cf5896090449c7fd074796f683c164e2bff782a46390cd43eee6202f19b.jpg" data-media-id="editor_7" data-image-id="20240907160944_81860cf5896090449c7fd074796f683c164e2bff782a46390cd43eee6202f19b" data-rendition-name="original" width="780" height="539" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Rock failure from Annapurna IV led to a series of cascading events that resulted in the Seti River flood of 2012 that killed 72 people. Map: J  KARGEL / D REGMI(Photo: Shristi Karki)</figcaption> </figure>  On 20 April 2017, a high altitude breakage of solid rock from the east face of Saldim Peak (6,388m) in the <a href="https://nepalitimes.com/here-now/nepal-s-mountains-are-melting">Barun Valley turned into a 1.1 million m3 debris flow</a> of ice and sediment that plummeted 1,200m down to the Langmale Glacial lake below. Although the lake was less than 0.01km2 in size, the combination of lake water with melting ice from the ice-debris flow triggered a massive hyper-concentrated flood that destroyed forests, pastureland, and trekking lodges for several dozen kilometres to the Barun’s confluence with the Arun. In India’s Uttarakhand state bordering Nepal, the Chamoli event of 7 February 2021 was catalysed by the detachment of 20 to 30 million m3 of rocks and ice from a frozen, ice-clad peak. The ensuing avalanche developed into a rapidly flowing mass of rocks, ice and water, killing 204 people and heavily damaging an under-construction hydropower infrastructure 35km downstream.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_c7284846f8a571d8d1f5596b7731e7c4c2521f764aaf9e5df23ad9d0ad41d986.jpg" data-media-id="editor_9" data-image-id="20240907160944_c7284846f8a571d8d1f5596b7731e7c4c2521f764aaf9e5df23ad9d0ad41d986" data-rendition-name="original" width="798" height="462" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>This massive breakage (below) of solid rock from Saldim Peak in 2017 fell on a lake and unleashed a flood downstream on the Barun River.

Similar processes may have been involved in the Birendra Tal glacial lake flood of 21 April 2024 and <a href="https://nepalitimes.com/here-now/lives-on-the-line-in-the-himalaya">the Thame flood of 16 August 2024</a>. Each of the above cases show the potential hazard over long distances related to process chains, especially in connection with impacted mobile water bodies in glacial lakes and artificial reservoirs.&nbsp; <h2>12 TIPS: Awareness and Protective Measures</h2> Changes in high altitude permafrost, and the devastating geomorphic events they cause are still poorly understood by Nepal’s scientific community and government. Earthquakes and heavy rainfall are usually reported by the press to be the primary causes of catastrophic events, both of which are impossible to predict. However, climate change and gravity, the two major forces at work on Himalayan permafrost, are constants. As permafrost continues to destabilise at the highest altitudes in the Nepal Himalaya, more and more devastating events can be expected to occur.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_dd2d77fb090fb2f5c836411d61bd6e7bb4e2e40ea2abae3d8eee8a686e9457dc.jpg" data-media-id="editor_13" data-image-id="20240907160944_dd2d77fb090fb2f5c836411d61bd6e7bb4e2e40ea2abae3d8eee8a686e9457dc" data-rendition-name="original" width="977" height="733" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> <figcaption>Gabions installed near Chukung in 2015 protected the village from a similar flood from the Lhotse Glacier in 2014. Photo: ALTON BYERS(Photo: Shristi Karki)</figcaption> </figure>  The question is, what can we do about it? Based on our collective experience in the European Alps, Peruvian Andes, and Nepal Himalaya over the past several decades, we offer the following suggestions: 1. Encourage more permafrost and hazard research. Nepal’s scientists and practitioners need to better understand and acknowledge the role of permafrost change in the growing list of climate change-related impacts in the high mountain environment, and more research of an applied nature is indicated. Interdisciplinary approaches that include and involve local people usually yield the most promising and effective results. 2. Standardise glacial lake risk assessment methods. Currently, scientists use various methods to assess a lake’s potential danger of flooding, with predictably mixed and widely differing results. Imja glacial lake in Khumbu, for example, is considered by some scientists to be extremely dangerous, and by others to have a low to moderate risk. The result is confusion among local people, local governments, and scientists alike. 3. Update and revise the current list of potentially dangerous glacial lakes in Nepal. The inventory should incorporate the changing permafrost factor, including smaller lakes less than 0.01km2. Even very small glacial lakes, such as those above Thame and the Langmale glacial lake in the Barun, can be as destructive as large lakes under the right conditions and cascading processes. 4. Develop new feasibility study protocols for large hydropower projects. These guidelines must incorporate the changing permafrost factor as well as the heightened threat of glacier floods. The potentially disastrous impacts of climate change upon major hydropower projects in Nepal have been predicted by scientists for decades, and yet the construction (and destruction) of major, multi-million-dollar installations continues. Hundreds of lives, and millions of dollars of infrastructure, stand to be saved through the use of more detailed, comprehensive evaluations of permafrost and glacier-related risks prior to project implementation. 5. Develop zoning policies. These should discourage the location of farms and infrastructure (homes, tourist lodges) within known and active floodplains. Some scientists believe that most of the deaths from the 2012 Seti flood could have been prevented had settlements not been located directly in the floodplain. 6. Simple is beautiful. Rock-filled wire cages (gabions) can be engineered to effectively divert floods and should continue to be promoted in high mountain regions. In the village of Chukung located directly in the floodplain of the Lhotse Glacier in the Sagarmatha National Park, for instance, the installation of gabions after a glacier flood in 2015 protected the village the following year when a second similar flood from the same glacier occurred.  <figure> <img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20240907160944_ce975f82275c7936c7948fbf7fd7231b61adecc01d5510760144a8f3d0467859.jpg" data-media-id="editor_14" data-image-id="20240907160944_ce975f82275c7936c7948fbf7fd7231b61adecc01d5510760144a8f3d0467859" data-rendition-name="original" width="1005" height="695" loading="lazy" alt="The not so permanent frost Page 6-7 #1228 NT"> </figure>  7. Build higher bridges. This can effectively address the growing frequency and magnitudes of glacier floods in the high mountains, eliminating the need for continuous rebuilding. 8. Increase awareness. Nepal’s mountains will continue to destabilise and become even more dangerous in future. Exercising extra caution while crossing a landslide, an active torrent, or a debris-covered glacier is a fact of life in today’s high Himalayan regions. Likewise, constructing a lodge, school, or community building beneath a small and seemingly harmless glacial lake should be discouraged. 9. Promote simple and effective early warning systems. In spite of their much-touted role in disaster mitigation, early warning systems installed to date at potentially dangerous glacial lakes in Nepal have proven to be expensive disappointments. They are typically installed by a remote and distant government agency, little training in their use by local villagers is offered, and local people say they have no idea what the warning sirens sound like nor what they should do if one goes off. Thus far the most effective and proven EWS tool has been the cell phone. Hundreds of lives were saved during the Seti River flood of 2012 when upstream witnesses phoned warnings to their downstream family and friends. 10. Improve mechanisms that allow scientists to communicate. The results of their permafrost and glacier hazard research should directly, quickly, and effectively be communicated to decision-makers. This has proven to be easy to recommend but difficult to implement in most of the world but is nevertheless in need of our constant efforts to achieve. 11. Encouraging transboundary permafrost research. Increased cooperation between scientists and researchers in Nepal, China, and India is needed to help identify potentially vulnerable crossborder rockfall, avalanche, and catastrophic flooding risk. 12. Develop and implement adaptation planning. Continue planning and training programs targeted at permafrost-related floods and other highland-lowland hazards. Local Adaptation Plans for Action (LAPA) have proven to be an effective tool for increasing local awareness of climate impacts as well as planning for mitigation measures.

It also has pointers on what must be done urgently to reduce its impact.The IPCC report contains the most direct correlation scientists have drawn between <a href="https://www.nepalitimes.com/editorial/a-hotter-himalaya/" target="_blank" rel="noopener noreferrer">climate change and extreme weather</a> around the world.‘The frequency and intensity of heavy precipitation events … and droughts have increased since the 1950s,’ the report states with ‘high confidence’, adding that human-induced climate change is likely the main driver.It adds categorically: ‘Increases in monsoon precipitation since the 1980s have resulted from rising GHG (greenhouse gas) concentrations … Monsoon precipitation is projected to increase in the mid- to long term on a global scale, particularly over South and Southeast Asia.’<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141128/636cfc6e9c7e80680e0a0b8bjpeg.jpg" alt="" width="1988" height="1024"><figcaption>Source: IPCC</figcaption></figure>It predicts that these heavy precipitation events will intensify and become more frequent in most regions as the world continues to warm. Globally, there will be 7% more <a href="https://www.nepalitimes.com/editorial/climate-damage/" target="_blank" rel="noopener noreferrer">extreme weather</a> for every 1° Celsius of global warming.Even under the best-case scenario of reduced greenhouse gas emission, global average temperature is set to exceed 1.5°C by the turn of the century. <a href="https://www.nepalitimes.com/banner/a-biden-presidency-climate-and-the-himalaya/" target="_blank" rel="noopener noreferrer">The Himalaya</a> will get hotter faster than other parts of the world, and could warm by 1.8-2.2°C.The main conclusions of this IPCC report were leaked to AFP in June, and predicts global surface temperatures increasing until at least the mid-century even under the best scenario. The warming will ‘exceed 2°C during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades’.The 2015 Paris Agreement recommended capping global warming at ‘well below 2°C’ above pre-industrial levels, and to 1.5°C in the next 30 years by reducing emissions. However, the increase is already at 1.2°C Celsius, and on track to exceed 2°C.This will lead to <a href="https://www.nepalitimes.com/banner/between-existence-and-extinction-in-nepal/" target="_blank" rel="noopener noreferrer">mass species extinction as ecosystems collapse</a>, more <a href="https://www.nepalitimes.com/banner/mosquitoes-move-up-mountains-as-the-earth-warms/" target="_blank" rel="noopener noreferrer">widespread diseases</a>, heatwaves making parts of the world unfit for human habitation, cities and small island nations at risk of being submerged by sea level rise.For Nepal, even a 1.5°C rise in global temperature will mean <a href="https://www.nepalitimes.com/editorial/manpower-and-hydropower/" target="_blank" rel="noopener noreferrer">heavy precipitation and associated flooding</a> of the kind the country saw in 2018 and this year.

Source: IPCC</figcaption></figure>This is even truer for the Himalaya because of its proximity to the equator. Scientists say it is already warming up to 0.3-0.7°C faster than the global average due to a phenomenon called ‘Elevation Dependent Warming’. But at the current trajectory, the mountains may see warming of up to 5.7°C during this century. In such a scenario, the <a href="https://www.nepalitimes.com/banner/a-terrifying-assessment-of-himalayan-melting/" target="_blank" rel="noopener noreferrer">Himalaya will lose two-thirds of permanent ice</a>, and most glaciers will have melted.It predicts that even if greenhouse gas emissions are curtailed, <a href="https://www.nepalitimes.com/banner/the-third-pole-is-warming-faster-than-expected/" target="_blank" rel="noopener noreferrer">mountain and polar glaciers will continue melting</a> for decades or centuries. This will impact not just Nepal but about 1 billion people living downstream from the Himalaya in China, India, Bangladesh and southeast Asia.‘Human influence has likely increased the chance of compound extreme events since the 1950s, increases in the frequency of concurrent heatwaves and droughts on the global scale, fire weather in some regions of all inhabited continents, and compound flooding in some locations,’ the says the IPCC report, almost describing the winter drought, <a href="https://www.nepalitimes.com/here-now/weve-seen-fire-and-weve-seen-rain/" target="_blank" rel="noopener noreferrer">wildfires and floods that have ravaged Nepal</a> in the past 8 months.The main cause of all this warming is that in 2019, atmospheric CO2 concentrations were higher than at any time in at least 2 million years. Global surface temperature averaged over 2081–2100 will be higher by 1.0°C to 1.8°C compared to pre-industrial levels even if emissions are controlled in the next 30 years.The IPCC report summary says that the only solution is for world governments to immediately agree on reaching net zero anthropogenic CO2 emissions to stabilise human-induced <a href="https://www.nepalitimes.com/opinion/climate-for-change/the-great-himalayan-thaw/" target="_blank" rel="noopener noreferrer">global temperature increase</a>.If the biggest carbon emitters like India and China meet cut back targets, under the most optimistic scenario global average temperature would stabilise at below 1.5°C toward the end of the 21st century after overheating by 0.1°C. But experts do not sound very optimistic about this happening.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221110141128/636cfc749c7e80680e0a0b8djpeg.jpg" alt="" width="2006" height="986"><figcaption>Projected global temperature rise under the intermediate, high and very high GHG emission scenarios considered.

This will also clean up the air, dirty air killed 41,000 people in Nepal in 2019.It is a sign of just how desperate the situation is that the IPCC scientists say in their report that the only hope for life on the planet may be a major volcanic eruption this century that would reduce global surface temperature because the sun will be blocked out for 2-3 years.The reports says rather phlegmatically: ‘If such an eruption occurs, this would therefore temporarily and partially mask human-caused climate change.’

UN climate report declares planetary emergency

A little more than one month into its six-month term, Nepal's interim government recalled ambassadors from 11 countries: China, Japan, Malaysia, Qatar, Saudi Arabia, Israel, Russia, Spain, Germany, the UK, the US, and Japan.&nbsp;
Mostly appointed by previous governments, they have to return to Kathmandu by 6 November. The envoys who were retained, even if they were political appointees, tended to be women or from various ethnic minorities.
The recall has met with criticism back home. Prime Minister Sushila Karki is blamed for borrowing a page out of its predecessors’ playbook. Although it was a symbolically inclusive move in a diplomatic corps dominated by established groups, the government may have got its timing wrong.
On Sunday, however, the Supreme Court issued an interim order against government decision to recall the 11 ambassadors. The court questioned the neccesssity and justification of such a move, concerned that it could affect Nepal's relations with the host countries.&nbsp;
Karki has said <a href="https://nepalitimes.com/news/future-imperfect">her priority is to hold elections in March</a>, and by recalling Nepal’s emissaries from important capitals like Washington, London, Bonn, Tokyo, Abu Dhabi and Kuala Lumpur her government has cut channels of communication and support from development partners and with the international community.&nbsp;
Nepal’s anti-corruption GenZ protest and the devolution of the youth movement into <a href="https://nepalitimes.com/here-now/relocate-reallocate-recover">arson, looting, and violence</a> after the targeted killing of protestors in September put the nation in the international spotlight. And the interest was especially keen in neighbouring New Delhi and Beijing.&nbsp;
The Nepal unrest has sparked similar protests across the world from <a href="https://nepalitimes.com/here-now/nepal-genzs-inspired-filipinos">the Philippines</a> to East Timor, Madagascar and Peru. But there is also worry in India where exposure of #nepokids on social media as well as corruption in high places could instigate copycat youth unrest.
And in China, there is still a lingering memory of the deadly protests in 1989 Tiananmen Square. But the Chinese also suspect that some in the GenZ movement have links to free-Tibet. &nbsp;
Foreign policy experts in Nepal reject conspiracy theories about foreign backing for the GenZ, characterising it as mostly triggered by home-grown outrage over chronic corruption of the governing elite.&nbsp;
Throughout its history Nepal has always had to balance the geo-strategic interests of its neighbours: the British in India and the Chinese Empire, and more recently independent India and Communist China.
When former PM K P Oli resigned, he had <a href="https://nepalitimes.com/opinion/comment/when-xi-meets-modi-and-oli">just returned from a visit to Beijing</a> and was a week away from making an official visit to India. A new Nepali prime minister typically makes the first visit to India, but Oli broke that tradition last year by going to China to sign the Belt and Road Initiative (BRI) framework agreement.
"Oli was China's trusted partner supporting <a href="https://nepalitimes.com/news/china-syndrome">Nepal’s participation in BRI</a> and SCO (Shanghai Cooperation Organization)," says geopolitical analyst Sanjay Upadhya. "Now, some in Beijing are apprehensive that there is external support for the youth protests that contributed to Oli’s sudden departure. It is perceived as a strategic setback for China."
Despite an ongoing dispute with India over a 364 sq km border territory, Nepal is heavily dependent economically on India with which it has an open border.&nbsp;
Rulers in Kathmandu have usually leaned over backwards to be closer to China to counterbalance India’s gravitational pull following a strategy of ‘equidistance’ between the two giant neighbours.&nbsp;
Growing American and Western disinterest in the region is making India and China more assertive towards smaller nations. Educator Dovan Rai says, “China is also becoming more aggressive and trying to show its presence in and around South Asia.”
She adds, “Nepal is an important neighbour for China, especially considering issues it regards as sensitive, like the Dalai Lama and Tibet.”
Indeed, the Chinese are said to be suspicious about the links that the <a href="https://nepalitimes.com/here-now/nepal-s-historic-youth-dissensus">GenZ movement</a> was infiltrated by elements linked with Free Tibet or with US-based interests.&nbsp;
What must have especially raised eyebrows at the Chinese Embassy in Kathmandu was that the Dalai Lama’s office in exile in India congratulated Sushila Karki — the first time in history it has sent such a greeting to a new prime minister of Nepal.&nbsp;
Although Nepal’s two neighbours do not see eye-to-eye, both agree and are worried about instability in Nepal, and if it might trigger a refugee crisis, empower extremist factions, or attract Western interference.&nbsp;
Nepal’s September protests were preceded and succeeded by similar movements in the region and around the world. In light of this global eruption of youth frustration, and desire to lead from the front, the hardline governments of Nepal’s two neighbours are undoubtedly wary of the possibility of similar unrest within their own borders.&nbsp;
‘India advocates democratic legitimacy, while China prioritises control and predictability. Recent upheavals demonstrate that neither democracy nor stability alone suffices for sustainable nationhood,’ Upadhya wrote in a recent blog.
With early elections scheduled for 5 March, <a href="https://nepalitimes.com/news/one-month-later">the main challenge for Karki’s transition government</a> is to maintain dialogue and establish consensus between youth groups, political parties, and other agitating forces to participate in polls — all while ensuring there is no covert external influence.&nbsp;
Indeed, with <a href="https://nepalitimes.com/here-now/nepals-democracy-keeps-doubting-itself">Nepal’s democracy</a> at stake as well as new political forces with competing interests set to battle it out in a new political landscape, experts warn that there could be powers that will want to fish in troubled waters.&nbsp;
Explains Dovan Rai: “Along with soft power, foreign countries including our neighbours could intervene in the online information space to promote their interests in Nepal. Fake narratives and disinformation could be spread &nbsp;through digital platforms. We must be careful and vigilant about our digital space.”

Climber, expedition leader and later a supplier of bottled oxygen to Himalayan mountaineers, Henry Barclay Todd died on 3 November 2025 in his favourite place on earth, Kathmandu.&nbsp;
Todd was larger than life, a metaphor often used, yet it could not be more fitting. Standing nearly 2m tall, and possessing an unshakeable will, he lived life on a grand scale, both in body and spirit.&nbsp;
Todd was a pillar in the Himalayan climbing community, supporting many mountaineers across Nepal and Pakistan, making it possible for them to fulfil the dream of standing on the world’s highest peaks. He believed deeply in the strength, skill, and potential of the Sherpa people, and offered them opportunities that might otherwise have remained out of reach.&nbsp;
“Thank you, Henry. Your trust changed my life. Rest in peace, my leader, my teacher, my friend,” said Dorjee Gyelzen Sherpa in his tribute.
Born in 1945 to Royal Air Force officer Henry Todd and May Todd of the Women’s Royal Air Force, Henry spent his early years in Singapore. He led a lively childhood with his two brothers, far removed from the mountains that would later define his path.&nbsp;
A gifted swimmer like his father, Henry never pursued the sport professionally. Instead, after returning to Dundee as a teenager and attending seven different schools, he set off for London, where he began working for an insurance company before finding his true calling in adventure.
Henry Todd first came to Nepal in the mid-1980s and made his first attempt on Ama Dablam in 1987, an expedition that marked the beginning of an extraordinary and colourful climbing career. <a href="https://www.himalayandatabase.com/" target="_blank">The Himalayan Database</a> lists 61 expeditions that he led in Nepal alone — there were more in the Karakoram, Argentina and the Alps.&nbsp;
But Todd would joyfully say that a few hard Scottish ascents held a more personal meaning to him than even the greatest Himalayan summits.
Over the decades, he crossed paths with many legendary climbers like Anatoli Boukreev, Jerzy Kukuczka, Doug Scott and Chris Bonington as well as celebrities including members of Pink Floyd and Nobel Prize laureates whom he befriended.&nbsp;
He had a gift to never name-drop, but would simply mention that he had had lunch with Minnie Driver (niece of his long-time friend Andra) or that he had bought his first car from Donald Sutherland. For Todd, these were not bragging rights, they were simply part of the colourful tapestry of his life.
Todd’s life was filled with extraordinary experiences from surviving plane crashes, avalanches and earthquakes to quietly solving countless problems, which was one of his favourite past-times. His hands, famously large and steady, were always ready to help whether in the chaos of the mountains or the calm of a base camp.&nbsp;
With his sharp sense of humour and the beloved exclamation “Whoopie!”,he could bring lightness even to the toughest moments. He never tired of taking on challenges or helping when someone was in need, and he enriched so many people’s lives with his endless stories.
His legacy is immense. He helped build the human backbone of Himalayan climbing, enabling generations of climbers to test themselves in the world’s highest places. With his passing, an era of bold, spirited Himalayan guiding has come to a close.
Todd survived by a loving family, many close friends and a global community of climbers and Sherpas who will never forget him and his endless tales.&nbsp;
His family said in a statement: ‘Henry’s strength, warmth and unyielding belief in others will live on far above the clouds. He was indestructible in our eyes and in our hearts, he always will be.’
There will be a memorial service at Pashupati Temple in Kathmandu on 8 November 2025 around lunchtime.

The autumn mountaineering season is not over yet, and already there have been 12 fatalities on Himalayan peaks in Nepal.
Of the 1,450 climbing permits issued, 436 were for Mt Ama Dablam (6,812m), 374 for Mt Manaslu (8,163m) and 186 for Himlung Himal (7,126m). There were deaths on all three mountains.
The death of two French climbers on Ama Dablam happened before unseasonal blizzards hit the mountains. But Cyclone Montha from the Bay of Bengal brought on high winds and up to 1m of snow in the peak trekking and mountaineering season.
This increased avalanche conditions, and made helicopter evacuation of stranded and injured climbers difficult. Lower down the mountains, more than 1,000 trekkers from Nepal and around the world were stuck in the Annapurnas, Manaslu circuit and the Khumbu.
However, there have also been allegations that it was not just the weather that delayed rescues. Multiple levels of bureaucracy and the need for flight permits to restricted areas like Manang and Manaslu critically delayed evacuation flights.
Italian climbers Farronato Stefano and Caputo Alessandro were found dead in their tent at Panbari Himal Camp I (6,887m) in the Manaslu area. They had been trapped by heavy snowfall since 28 October, and their bodies were found on 4 November by a team from the expedition organisers, Sherpa Alpine Trekking Service. The team was made up of high level mountain guides and expedition leader Valter Perlino.
The team had been climbing to Camp 3 but decided to descend to base camp because of thrombosis in Perlino’s left foot. The two climbers who would eventually get trapped decided to break at Camp I, a decision that would prove fatal after the projected six-day snowfall arrived two days early.
“They were sleeping in a tent and were buried under 2.5 metres of compacted snow. It happened during the night between Thursday and Friday. While they were sleeping, absurd,” said Perlino.
A deadly incident took place the morning of 3 November, when five foreigners and two Nepalis died in an avalanche on Yalung Ri at 5,630m in the Rolwaling. They were part of a larger group of 15 that were acclimatising for an attempt on the nearby Dolma Khang (6,332m).
Local authorities in Gauri Shankar Conservation Area say calls were immediately made to helicopter companies as well as various ministries in Kathmandu that have to issue permits to fly to the region bordering China.
But the permits for rescue flights to Rolwaling Valley were delayed by eight hours. Rescue flights in these areas require permission from the Ministry of Tourism, the Ministry of Defence, the Home Ministry, and the Civil Aviation Authority of Nepal (CAAN).
Experts say this should be exempted in times of emergency when time is of the essence. CAAN spokesperson Pratap Babu Tiwari claimed to not know of the avalanche on Yalung Ri and deflected questions to the permission department.&nbsp;
There was a similar tragedy on Himlung Himal in Manang as well. Australian Chin-Tark Chan, 49, was climbing with 8K Expeditions and fell ill on 27 October at about 6,800m, developing snow blindness and loss of mobility. The guides immediately called the US insurance company Global Rescue for authorisation of a longline rescue.
Global Rescue refused, saying a rescue at that height would violate Nepal’s aviation rules and put the pilot at unacceptable risk. They asked the guides to transport Chan to Camp 3 at 6,400m to a permitted altitude. Seeing it was a life-or-death situation for its client, 8K called in an aerial rescue anyway, but the helicopter could not land due to bad weather. Chan died slightly below Camp 3 on 29 October.
Global Rescue said in a statement that it was ready to send in a helicopter after Chan had been transported to Camp 3, but several hours were lost for that attempt, and the weather did not get better in the next few days.
To underscore just how dangerous helicopter rescues in the Himalaya can be in bad weather, a chopper from Altitude Air skidded off the helipad at Lobuche below Mt Everest while trying to rescue trekkers in whiteout conditions.&nbsp;
CAAN announced a ban on flights during blizzards or dense fog. While rescue missions are often heroic and courageous, they should not be foolhardy if conditions are unsafe and the risk to pilots and rescuers too high. This autumn was a lesson for future expeditions and for the Nepal government.&nbsp;
The Italian duo on Panbari were caught out by snow that arrived two days ahead of schedule, but the group on Yalung Ri should have postponed their ascent after multiple warnings from the Department of Hydrology and Meteorology to avoid high altitudes.

Deadly autumn in Himalayan climbing

Traditional donors have sharply scaled back their aid commitments to developing countries over the past year. Some, like the United States, have virtually eliminated their aid programs. According to the Organisation for Economic Co-operation and Development (OECD), official development assistance (ODA) from member countries <a href="https://www.oecd.org/en/about/news/press-releases/2025/04/official-development-assistance-2024-figures.html" target="_blank">declined by 7.1%</a> in 2024, its first annual drop in six years. This trend was not limited to a few major donors. Of the 33 members of the OECD’s Development Assistance Committee (DAC), 22 slashed their aid budgets, and only four countries met the United Nations’ target of allocating 0.7% of gross national income to ODA. The outlook for the coming year offers little hope for improvement, as major DAC donors have announced additional cuts. Most notably, US President Donald Trump’s administration has suspended most foreign aid and dismantled the Agency for International Development (USAID), which dispersed most US government aid dollars. Meanwhile, the United Kingdom plans to <a href="https://www.bbc.com/news/articles/clyrkkv4gd7o" target="_blank">reduce aid spending</a> from 0.5% of GNI to 0.3% by 2027. Similar retrenchment across Europe and North America is reshaping international assistance, disrupting humanitarian and climate-related programs, and creating financing gaps in critical sectors such as health, education, and clean energy. In our 2017 book <a href="https://www.cambridge.org/core/books/going-beyond-aid/B48F59C6D8D2790D403A1A0C44B37612" target="_blank">Going Beyond Aid</a>, we urged developing-country governments to reduce their dependence on foreign aid, not only because it was becoming an unreliable source of funding, but also because other, better ways of financing development were becoming more available. That message is more urgent than ever. As reliance on aid becomes untenable, the international community must mobilise a broader array of financing sources to advance green and sustainable growth. This includes national development banks, industrial investment funds, sovereign wealth funds, and institutional investment in public markets, as well as innovative mechanisms such as debt swaps and public-private partnerships (PPPs). These tools can unlock domestic resources, attract long-term investors, and create synergies between public goals and private capital. Equity investment offers a promising avenue for engaging non-traditional development partners while reducing developing countries’ dependence on debt. Government investment funds, public and private financial institutions, and other private actors can participate by taking equity stakes in public enterprises, financing infrastructure projects, or joining PPPs. Such participation not only alleviates debt burdens but also improves the performance and management of public assets. As government-funded, mission-driven institutions, public development banks (PDBs) have the potential to provide patient capital for green and sustainable investment in emerging and developing economies (EMDEs). Building on the <a href="http://www.dfidatabase.pku.edu.cn/index.htm" target="_blank">pioneering database</a> of public development and financial institutions created by the Institute of New Structural Economics at Peking University, future research can identify effective ways to harness these institutions to fuel low-carbon growth. Responding to growing demand from the economies of the Global South, development partners have increasingly adopted an “entire value chain” approach to the green transition in recent years. This strategy facilitates transfers of low-carbon technologies, diffusion of digital innovations (including trade in services), and industrial modernisation, enabling countries included in China’s Belt and Road Initiative (BRI) to accelerate their shift toward sustainable development. Empirical research supports this approach. An analysis covering 139 countries <a href="https://ember-energy.org/latest-insights/the-first-evidence-of-a-take-off-in-solar-in-africa/" target="_blank">finds</a> that, following policy directives to incorporate green and low-carbon principles into the BRI, carbon intensity (CO₂ emissions per unit of GDP) among participating countries declined significantly between 2013 and 2022. These findings are consistent with another <a href="https://ember-energy.org/latest-insights/the-first-evidence-of-a-take-off-in-solar-in-africa/" target="_blank">recent study</a> showing how China’s solar-energy expansion has helped transform Africa’s power sector. Investment in infrastructure and industrial development can also generate positive spillover effects. Evidence from Sub-Saharan Africa <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jors.70023" target="_blank">shows</a> that the presence of at least one Chinese-financed infrastructure project in a second-order administrative region (comparable to a municipality) is associated with a 5% increase in nighttime luminosity – a widely used proxy for economic activity. Neighbouring regions experienced a 10-15% rise in luminosity, indicating that the benefits of such projects extend well beyond the immediate investment site.  <figure><img src="https://publisher-publish.s3.eu-central-1.amazonaws.com/pb-nepalitimes/swp/asv65r/media/20251104131124_1a11d248a89b0785bc7d7f1d9f721e7e7a2563cbd579c3c672a0900220c19171.jpg" data-media-id="editor_7" data-image-id="20251104131124_1a11d248a89b0785bc7d7f1d9f721e7e7a2563cbd579c3c672a0900220c19171" data-rendition-name="original" width="720" height="405" loading="lazy" alt="development aid and China"></figure>  These outcomes underscore the critical role of infrastructure investment, particularly in energy and transportation projects. By improving electricity access, affordability, and connectivity, they reduce energy poverty, bolster public services, and stimulate economic activity in underserved areas. To meet the evolving challenges of development finance, both traditional and non-traditional donors and creditors should move beyond aid and adopt multidimensional strategies that combine trade, investment, infrastructure, green technology, and digital connectivity, including fintech solutions, to support EMDEs. Importantly, such collaborations should be viewed as a mutual learning process in which partners assume complementary roles and shared responsibilities. To be sure, there have been missteps along the way. China’s financing of coal-fired power plants before 2021, for example, had slowed reduction in CO₂ emissions. But these outcomes, once recognised as policy errors, can help strengthen accountability and foster self-correcting mechanisms within the international development ecosystem. Through ongoing learning and adaptation, global partners can build a more resilient, inclusive, and sustainable framework for development finance. © <a href="https://www.project-syndicate.org/">Project Syndicate</a> Justin Yifu Lin, a former World Bank chief economist and Senior VP, is the honorary dean of the National School of Development and director of the Institute of New Structural Economics at Peking University.

Development finance must shift away from aid
