Even just reaching Base Camp in northeastern Nepal, at 5,364m, is a difficult trek. But for Kami Rita Sherpa climbing Everest has been a routine for over two decades, sometimes twice or even three times a year.Born in Thame in a side valley of Khumbu district, he started working as a porter for trekking companies when he was just 12.Now 52, Kami Rita climbed Mount Everest for the first time in 1994 when he was just 24. This year, Kami Rita reached the summit for the 26th time, a new world record.On a sunny monsoon morning in July, he spoke to The Third Pole in a café in Kathmandu. The rainy season is when Mt Everest is closed for climbing, and Kami Rita had a bit of leisure time between the spring and autumn climbing seasons.The Nepal government <a href="https://www.bbc.co.uk/news/science-environment-61828753">reportedly wants to move Everest Base Camp</a> to a lower elevation, because of risks associated with climate change. The Khumbu Glacier on which the camp is located is melting, with a river running through the ice. There is also a waste disposal problem in spring, with 1,500 climbers camped out for at least two months. But as Kami Rita explains, the plan is not supported by all. Excerpts of interview:<figure><figcaption>"Moving base camp will create chaos," says Kami Rita Sherpa. Photo: RAMESH BHUSHAL</figcaption></figure>What is your opinion about the government’s plan to move Everest Base Camp?There is no valid reason to move it. Do you think climate change has impacted just Base Camp? What about the other camps on the Everest route? Where will you shift them? If you say climate change has impacted Base Camp, then don’t you think the other camps have also become riskier due to rapid melting of the ice?Moving Base Camp will create chaos. The camps were established on the basis of the availability of a suitable and safe place, identified through experience and practicality. If you move Base Camp lower, say to the village of Gorak Shep at around 5,150m, then it will just be a stopover to the current base camp, as it’s nearly impossible to hike from the moved Base Camp to Camp I at 6,150m. And you can’t stay anywhere in between, as there isn’t any suitable spot except the current base camp. It will be just an added camp, not an alternative.But the government says it’s becoming more dangerous, and that the decision would create a safer environment for climbers and support staff.I don’t really think Base Camp has become unsafe or less safe. I think it’s the safest point to camp for preparation before heading up and there isn’t a place nearby that’s more suitable. If you move down a little, it’s even more dangerous. Currently, Base Camp is on the edge of the Khumbu Glacier, and moving it down a bit will take you near the foot of Pumori mountain. That’s the place where an avalanche occurred during the <a href="https://www.thethirdpole.net/en/livelihoods/over-750-killed-in-himalayan-earthquake/">2015 earthquake</a> and killed scores of climbers and Sherpas.If you move it further down to Gorak Shep where a flat area is available, which is over three kilometres to the south, then how would you provide water? There is no water source nearby and you must walk for an hour or so to get some water from the ice. Currently, Base Camp has meltwater from glaciers, and even when there is no meltwater, we can cut out the ice and melt it to drink. It would be nearly impossible to carry out expeditions at lower levels so far from glaciers unless there is a continuous supply of water. It’s about feeding over 1,500 people for over two months including climbers, porters and support staff, and we need a large amount of water every day.The Everest climbing route from Camp I to IV is on the Khumbu Glacier. Studies have shown that the <a href="https://www.thethirdpole.net/en/energy/almost-all-everest-glaciers-may-disappear-by-end-of-century/">glacier has been shrinking</a> due to rapid melting resulting from global warming. How has this affected climbing?Rapid melting exposes more of the rock face on mountains and it’s harder to climb rock than ice-covered terrain. It also increases the chances of rockfalls that could cause serious injury or even death. I have noticed more exposed rock, and the length of rock that has to be climbed has increased in the past two decades. Between Camp III and Camp IV, there used to be about 50m of rock when I started to climb Everest, but now it’s over 70m.Likewise, the Geneva Spur on the Lhotse Face at 7,300m has more rock as well. Between Camp IV and The Balcony near the summit, there is a vertical face that used to about 100m of rock to climb, but now it’s about 130m. The rock face on the Hillary Step is also taller than it used to be.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221114131124/637233959c7e80680e0c48ecjpeg.jpg" alt="" width="1399" height="741"><figcaption></figcaption></figure>What other changes have you seen on Everest since you started climbing?There are lots of changes. I can say that the amount of ice on Everest is less than when I climbed for the first time in 1994. Ice is melting at a faster rate and this change is moving higher up, but the bigger problem is that the timings of rain and snow has become irregular. In 1994 and the following expeditions for some years, there would be no water at Base Camp at the beginning of climbing in late April. The Glacier was all ice. We used to crack the ice and then melt it to drink. But now there is a stream of water running through Base Camp, and there are melt pools even at Camp II. This year in April, we got water in Camp II. Now I feel like Camp II is the new Base Camp.If shifting Base Camp is not a good idea, what do you think the government should do to ensure that climbing Everest in Nepal is safe?I think if a decision is made to move Base Camp, more expeditions will just move over to the north side in China. It’s already expensive and challenging to climb Everest from the Nepal side. The Tibet side in China has a lot of facilities and it’s easier to climb from the northern side rather than the southern one. China has electricity and roads right up to the Base Camp on the Rongbuk Glacier. You can go up to 6,500m on yaks. Why would someone come to the Nepal side if you prolong their stay without reason by creating a longer route?Instead of moving Base Camp, the government could spend money on providing electricity at the camp, so that we can reduce the use of gas to cook food. [The use of gas canisters by climbing expeditions <a href="https://everestchronicle.com/base-camp-diary-how-climbing-everest-have-changed-over-time/">has been suggested</a> as a factor in the warming of the area.] One expedition uses three gas canisters per day, and there are about 50 expeditions a year. One expedition takes around two-and-a-half months from Kathmandu and back, and most of the stay will be in Base Camp. You can reduce the use of gas if you provide electricity.Secondly, the government can spend money on providing folding toilets to all expeditions so that we don’t have to carry them every time, and they can charge for the usage. They could invest in providing more reliable weather information and focus on clean-up campaigns [of rubbish left by climbers] along the trail up to the summit.Just doing things to make a news headline won’t solve any problem. There are many more things that could be done to create a safer climbing environment and save the mountains, but an easy fix, like moving Base Camp down, is just a waste of time.What is your message to the world, which has responded very slowly to reduce carbon dioxide emissions, causing snow and ice in the mountains to melt faster?The mountains are not just ours. It’s not just Sherpas who would be impacted, or Nepal that would lose revenue from tourism if the snow and ice melts. It’s the source of water for billions of people. It’s the heritage of the world. If it’s gone, we are done. I think the only way to keep our mountains white is to reduce emissions from factories, planes and vehicles.I remember the Dalai Lama saying that one day we will die because there won’t be water to drink. I feel like that will happen some day soon. I would urge the global community to think about it seriously and act immediately. I can’t do much as a climber, except inform people about the situation out there.I just want to say that the ice on the mountains is vanishing. That’s my information based on experience and it’s up to you to make a decision.This article first appeared on <a href="https://www.thethirdpole.net/en/climate/moving-everest-base-camp-a-ridiculous-decision-says-record-holder-climber/">The Third Pole</a>.

“If the ice is gone, we are done”

https://youtu.be/RTnxJKo97DIFor many tourists trekking to <a href="https://www.nepalitimes.com/latest/re-measuring-mt-everest/" target="_blank" rel="noopener">Mt Everest</a> Base Camp this autumn, the trip will be an adventure of a lifetime. The thin clear air, stark landscape, and ice-tipped peaks pierce the inky sky providing great Instagram backdrops.However, what is stunning scenery to tourists is for climate scientists an apocalyptic sight. They see dramatic evidence all around of a rapidly warming atmosphere.Visitors returning to the Everest region after 20 years also notice changes: large lakes where there were none, glacial ice replaced by ponds, boulders and sand, the snowline moving up the mountains, and glaciers that have receded and shrunk.Read also:<a href="https://www.nepalitimes.com/opinion/climate-for-change/the-great-himalayan-thaw/" target="_blank" rel="noopener">The great Himalayan thaw</a>, Ajaya Dixit<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692eea9c7e80680e03c079jpeg.jpg" alt="" width="1400" height="1050"/><figcaption>HIMALAYAN MELTDOWN: The Khumbu Glacier is the highest in the world and receding at 30m/y.

The banks of the Bhote Kosi still bear the scars of the deadly flash flood in 1985 which washed off a long section of the <a href="http://archive.nepalitimes.com/blogs/thebrief/2014/05/19/everest-climbers-continue-in-nepal/" target="_blank" rel="noopener">Everest Trail</a> and the hydropower plant in Thame. It was caused by an avalanche falling into the Dig Tso glacial lake, causing it to top over.Further up near Tengboche, the <a href="https://archive.nepalitimes.com/page/not-out-of-danger-the-big-one" target="_blank" rel="noopener">Imja Khola</a> also bears signs of a huge glacial lake outburst flood that thundered down the western flank of <a href="http://archive.nepalitimes.com/news.php?id=12870#.W7XuTHszbIU" target="_blank" rel="noopener">Ama Dablam</a> in 1977. And below the formidable south face of Lhotse is Imja Tso, a lake 2km long that has formed and grown in the last 30 years. It does not exist on trekking maps from the 1980s. All these lakes were formed and enlarged as a result of global warming melting the ice.<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692eee9c7e80680e03c07ajpeg.jpg" alt="" width="1200" height="990"><figcaption>The Khumbu Icefall funnels debris and ice from the Western Cwm down to the Khumbu Glacier 1,000m below. </figcaption></figure><figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692ef19c7e80680e03c07bjpeg.jpg" alt="" width="1200" height="800"><figcaption>The Lobuje Icefall is now a hanging glacier, having retreated above the cliff.</figcaption></figure>The terminal moraine of the <a href="https://archive.nepalitimes.com/article/Book-Review/The-Everest,428" target="_blank" rel="noopener">Khumbu </a>Glacier looms 400m above Dughla. This is the debris bulldozed down from Mt Everest and surrounding peaks over millions of years, and represents the extent of the glacier’s advance in the last Ice Age. Today, the surface ice on the world’s highest glacier is all but gone due to natural and anthropogenic warming.For an even more dramatic glimpse of how global warming is changing the Himalayan landscape, there is nothing like an aerial perspective. Nepali Times got a chance last week to take these striking images of the terrain below Mt Everest. The barren beauty foretells of a time when this terrain will be stripped of much of what remains of its ice cover.Read also: <a href="https://archive.nepalitimes.com/article/nation/melting-mountains-shake,3073" target="_blank" rel="noopener">When melting mountains shake</a>, Kunda Dixit<a href="https://archive.nepalitimes.com/article/nation/ice-to-water-glacier-lake-outburts-himalayas-nepal,4197" target="_blank" rel="noopener">Ice to water</a>, C Scott Watson<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692ef49c7e80680e03c07cjpeg.jpg" alt="" width="1400" height="1050"><figcaption>Imja Tso did not exist in trekking maps 30 years ago.

The ice here has receded at an average of 30m/y in the past 20 years, but it has also shrunk vertically, losing up to 50m in thickness. Everest Base Camp was at 5,330m when <a href="http://archive.nepalitimes.com/blogs/thebrief/2018/01/13/commemorating-edmund-hillary/" target="_blank" rel="noopener">Hillary </a>and Tenzing climbed Mt Everest in 1953, today it is at 5,270m.The glacier is also getting flatter: the darker debris makes the ice beneath melt faster near Base Camp, but the thicker layers of boulders and sand further down insulate the ice. Glaciologists say this flatter profile means the ice moves slower, leading to more ponding, and more rapid melting of the ice underneath.The velocity of the glacier is 70m/y at Base Camp, and it slows down to 10m/y further below, but is zero at the terminus situated at 4,900m. This means the ice is decelerating as it is squeezed, and the pressure is being released by the melting of the ice mass.Researchers monitoring the supraglacial ponds say their area has grown by 70% in the past ten years alone. The ponds are fringed by ice cliffs and caves which accelerate the melting. The melted ice has carved an outflow channel through the left lateral moraine, so there is no large glacial lake on the Khumbu like as elsewhere in Nepal.Scientists conclude that the Khumbu Glacier is not about to vanish, and the Icefall is not going to turn into a water fall any time soon. However, the permanent ice catchment of the glacier above 6,000 could start to deplete under the worst-case ‘beyond catastrophic’ scenario of +5°C warming.Read also: <a href="https://archive.nepalitimes.com/article/interview/interview-with-david-molden-icimod,3074" target="_blank" rel="noopener">Nepalis paying price for climate change</a><a href="http://archive.nepalitimes.com/article/editorial/going-green-environment-day,3064" target="_blank" rel="noopener">Climactic change, Editorial</a><h4>Climate Eco Tourism</h4><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692efa9c7e80680e03c07ejpeg.jpg" alt="" width="1400" height="934">Will more tourists visiting areas threatened by global warming spread awareness and help save the planet, or will the energy they burn contribute to making the earth warmer?Both. Tour operators offer Antarctic cruises, trips to Greenland and the Arctic to observe calving glaciers up close. Many have scientists on board instead of tour guides, and the travel companies say the trips help spread environmental awareness.However, mass tourism also comes with its own enlarged carbon footprint and the very act of visiting the Himalaya to see melting glaciers may contribute to thawing them faster. The carbon emitted by a holiday charter plane to the Maldives, for example, leads to sea level rise that may ultimately submerge the archipelago nation by the end of the century.However, as awareness grows about the effects of global warming in the poles and the ‘Third Pole’ (as the Himalaya is called) there is also increasing interest among the public to see up close the impact of climate change on the mountains. Many trekkers visiting Nepal are eco-conscious and aware that their travel and stay in Nepal comes with a carbon cost.Read also: <a href="http://archive.nepalitimes.com/news.php?id=16562#.W7XuDHszbIU" target="_blank" rel="noopener">Defrosted</a>, Kunda Dixit<a href="https://archive.nepalitimes.com/article/Book-Review/The-Everest,428" target="_blank" rel="noopener">The Everest Industry</a>, Kunda Dixit<figure><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692efd9c7e80680e03c07fjpeg.jpg" alt="" width="1400" height="1050"><figcaption>HIMALAYAN MELTDOWN: The Khumbu Glacier is the highest in the world and receding at 30m/y.

Pics: Kunda Dixit</figcaption></figure>As they share their impressions on social media, there is evidence that climate tourism can indeed turn many visitors into environmental activists, or at least convince them to lead less carbon-intensive lifestyles when they get back home.Many environmentally sensitive visitors to Nepal these days calculate their carbon footprint from the aviation fuel per passenger on their flights to Kathmandu and Lukla, in taxi rides, and even the carbon emitted by the LPG gas in lodges along the Everest trail. And they try to offset all that by donating to agencies working on adaptation or mitigation of climate impact.Even so, there are critics of carbon offsetting who say that it is cosmetic and does not address the wasteful consumerism that is at the root of the climate crisis. They say trekkers on Everest hikes who buy carbon offsets are simply washing off their guilt, and shifting the responsibility to do something about global warming on someone else.On balance, however, there is a case to be made for climate eco-tourism creating jobs and benefitting the Nepal economy, ultimately allowing the tourism industry to introduce less carbon intensive technology. Tourists from all over the world can also see for themselves how the people suffering the most from the effects of climate change are the ones least responsible for it.There are websites to calculate your carbon footprint and how to offset the cost to the climate of your tour. There are also trekking agencies and airlines that try to minimise their carbon footprints.<a href="http://www.carbonfootprint.com/" target="_blank" rel="noopener">Carbon Footprint</a><a href="http://www.responsibleadventures.com/" target="_blank" rel="noopener">Responsible Adventures</a>:Mountain Helicopters: 01-4111032<h4>HOW MUCH CO2 DID YOU BURN TO GET HERE?</h4><img src="https://superdesk-pro-c.s3.amazonaws.com/sd-nepalitimes/20221107171112/63692eff9c7e80680e03c080jpeg.jpg" alt="" width="850" height="314">An economy class roundtrip passenger on a flight from London Heathrow to Lukla via Kathmandu emits 2.9 tons of carbon.
