Climbing experts and climatologists told ABC News that rising global temperatures are changing the terrain of the Himalayan glaciers and the weather patterns that mountaineers depend on to schedule their trips.

This year, a record number of individuals lost their lives while trying to ascend Mount Everest. Although experts agree global warming may not be solely to blame, the Nepalese government attributed the unusual number of deaths on climate change.
Recognizing the Effects of Everest Climbing on the Environment
1. Severe weather
On Mount Everest, the severe weather is one of the biggest obstacles that climbers face. The peak is well known for its severe and erratic weather patterns, which can change quickly and endanger the safety of climbers. Because Mt. Everest's top is situated in the "Death Zone," where oxygen concentrations are dangerously low, it is considerably harder to survive extreme weather.
On the mountain, blizzards, strong winds, and below-freezing temperatures are frequent occurrences. Because of the potential for avalanches, frostbite, and hypothermia, climbers must be well-prepared and wear clothes and equipment made for extremely low temperatures.
2. Sickness at Altitude
Another major obstacle that arises while climbing to such high heights is altitude sickness, often known as acute mountain sickness (AMS). The oxygen content of the air drops as climbers reach altitudes exceeding 2,500 meters (8,200 ft). Numerous symptoms, such as headaches, nausea, lightheadedness, exhaustion, and dyspnea, might be brought on by this oxygen shortage.
If treatment is delayed, AMS can develop into more serious conditions such high altitude cerebral edema (HACE) or high altitude pulmonary edema (HAPE), all of which can be fatal. To let their bodies to progressively adapt to the lower oxygen levels, climbers must spend many days at several camps along the route in order to adequately acclimate.
3. Mental and Physical Wellbeing
A high level of mental and physical fitness is required to climb Mount Everest. Climbers must undergo extended periods of intense physical exertion during the ascent, frequently carrying large packs and negotiating hazardous terrain. To endure the physical demands of the climb, climbers need to have exceptional muscular strength, endurance, and cardiovascular endurance.
Furthermore, mental toughness is just as important. Climbers need to be ready for protracted solitude, severe exhaustion, and suffering. Making wise judgments and protecting oneself depend on having the mental fortitude to endure fatigue and stay focused.
4. Technical Difficulties
In order to scale Mount Everest, one must overcome a number of technical obstacles that call for certain knowledge and expertise. The ascent involves climbing sheer rock faces, navigating crevasses, passing ladders over deep crevices, and navigating steep ice slopes.
Climbers need to know how to use mountaineering tools such ascenders, ropes, harnesses, crampons, and ice axes. In order to traverse the mountain's varied terrain, they also need to be proficient in more complex climbing skills like rock and ice climbing.
5. Congested Roads
Overcrowding on Mount Everest has grown to be a serious issue in recent years. An rising number of climbers seek the summit every year due to the appeal of ascending the highest mountain in the world. At certain points in the ascent, this congestion may form bottlenecks, resulting in delays and raising the possibility of accidents.
A shortage of necessary supplies like oxygen cylinders and fixed ropes may also result from the congested routes. Climbers need to make sure they have enough supplies to last them the whole trip and carefully plan their ascent to avoid peak periods when traffic is at its worst.
6. Effects on the Environment
Concerns over the environmental effects on Everest and its environs have been raised by the growing number of climbers making attempts to reach the summit. The delicate environment atop the mountain is under danger due to the buildup of trash, including human waste. Furthermore, using fossil fuels for heating and cooking while on an expedition adds to pollution and climate change.
7. Expenses
Expeditions to Mount Everest are expensive undertakings. Permits, gear, guides, Sherpa assistance, travel fees, and insurance are all part of the climbing costs. For many climbers, the heavy financial load can be a major obstacle that restricts their access to assistance and essential resources.
8. Stress on a psychological level
In addition to being physically taxing, climbing Everest is also emotionally taxing. Climbers' mental health may suffer from the extended exposure to adverse circumstances, seclusion from society, and ongoing threat to their lives. Anxiety, sadness, and other psychological disorders can result from uncertainty, the fear of failing, and the ongoing need to make decisions under pressure.
The mountains and glaciers' topography are less trustworthy.
Joseph Shea, an assistant professor of environmental geomatics at the University of Northern British Columbia, told ABC News that the overwhelming body of recent research has demonstrated that the Himalayan glaciers are decreasing. According to a 2019 paper written by Shea, the Himalaya area is being roasted by climate change, which is forcing permafrost to melt and glaciers to recede.
The Khumbu Icefall, which is close to the Everest base camp and is utilized to hike up to Camp 1, is one of the routes that climbers take to reach higher summits, and it depends on the stability of glaciers, Shea added.
Shea has been studying the Himalayas since 2012. "The Khumbu Icefall, which is already really difficult to navigate, that becomes less reliable," she added.
The window of ideal weather for Everest is become increasingly erratic.
According to study, the region's weather patterns are also getting more unpredictable, which makes it challenging for climbers to organize safe trips that last more than a few days.
According to Colorado-based meteorologist and climbing expedition weather forecaster Chris Tomer, Everest specialists are aware that there is a "magical" window in May when the winds drop below 30 mph, usually from May 15 to May 30, as he told ABC News.
According to Tomer, the window usually opens when the monsoon season draws near and the jet stream—a band of strong winds that usually resides atop the peak—is forced off, resulting in a sharp decline in local winds and better climbing conditions.
However, the timing has been shifting.
According to seasoned climber Alan Arnette, who is the oldest American to climb K2 at 58, most people will not ascend if winds are higher than 30 mph, he told ABC News.
"It's just too dangerous, and it increases the chance of frostbite and other problems," he stated.
One important indication of climate change is the Himalayan area.
According to the specialists, there are obvious signs of climate change in the majority of glacier mountain regions worldwide.
According to research, glaciers would continue to lose mass and recede significantly if greenhouse gas emissions are not significantly decreased, Shea warned.
Most of the deaths on Everest this year are probably not attributable to climate change.
In contrast to the typical of four to six climbers every season, 17 climbers lost their lives while attempting to reach the summit of Everest this year, according to Arnette.
Although the Nepalese authorities attributed the sharp rise in Everest mortality to climate change, most of the deaths were probably caused by incompetent or unskilled guides. According to the climbing professionals.
Eleven of the 17 fatalities, according to Arnette, might have been avoided. As usual, Arnette added, a number of the fatalities were attributed to natural causes.
