Khumbu Glaciers: Calm but alarming.

November 26, 2017
Khumbu and the surrounding resigns are the prime source of the water for about 40% of the world population. Glaciers and glacier lakes from there awaking the whole world to take deep concern seriously on them. We must understand what happening in theses glaciers and glacier lakes, is critical to predict their response to global warming. Research shows that increasing global temperatures are thawing the glaciers and ice at high elevation is disappearing rapidly. Shrinking of the Khumbu Glacier and chances of higher frequency of avalanches are the major problem in the khumbu region like in the 2014 that kills 16 Sherpas. Besides these the meltwater naturally pools on the surface of the Khumbu Glaciers and these ponds don’t disappear, but instead coalesce into small lakes. In research shows that this kind of ponds on the lower part of the Khumbu Glacier increased in size by 84% from 2009 to 2015.Though the researchers aren’t predicting such an outburst any time soon in this region, but it’s still a concern. In coming years, it may be big issue. No doubt to say it’s alarming. We have simple solutions at hand to dramatically reduce problems to make safer world to future generations just Reduce the emission, stop deforestation, Fight misinformation and prepare for impacts.
  • The Khumbu Icefall and Khumbu Glacier are the major attraction for both mountaineers and Climate Researchers. It is one of the most famous and often visited Himalayan Glaciers as it is the key route for climbing Mount Everest, about 12 km long which is under shrinking. The Mt. Everest 8848m, Nuptse7879m, Lhotse8501m, The Khumbu icefall, Glaciers, Debris, Moraines, Meltwater pool, Glacier lakes and Khumbu Terminus over there, are naturally calm and beautiful but challenging the world to protect and take opportunities from them.

  • The shrinking of glaciers will likely have a significant socioeconomic impact in the Hindu Kush Himalaya. Glaciers around the world have been retreating at unprecedented rates.
    The Khumbu Glacier is a large debris-covered glacier in the Khumbu region. About 12 km long, it drains mainly from the West Cwm between Mt. Everest and Lhotse and ranges in altitude from over 8000 meters to 4900 m. Research reports that the Khumbu Glacier is retreating at an average of 20m per year. The length of the glacier has shrunk from 12,040m in the 1960s to 11,100m in 2001. This 1 kilometer retreat has been consistently between 15 and 20 m per year during this interval.

  • The thick ice around the base camp of the Mt Everest has been disappearing exposing its rocks structure due to global warming and rising pollution level The melting glaciers will inevitably lead to ecological and environmental change too.

  • The meltwater forms pools naturally on the surface of the Khumbu Glacier. The glaciers’ terminal deposits (moraines) play the role of natural dams. Gradually the impounded lakes grow very large and the ice contained in the end of moraines can melt over time then they can burst out to make a GLOF.

  • Retreating glaciers will release meltwater and create lakes, leading to disaster.
    Moving glaciers carry land surface with them, creating ridges. This process drastically alters the landscape over the years.

  • One can easily witness, because of global warming, changes in the number and size of glacial lakes forming behind exposed end moraines as glaciers retreat, and the resulting potential threat of glacial lake outburst floods (GLOFs) in the Hindu Kush Himalaya region.(A panoramic view stitching 7 shots in Photoshop.)

  • Melting Glaciers - Temperature, precipitation, humidity, wind speed, and other factors such as slope and the reflectivity of the glacier surface all affect the balance between inputs and outputs. Most glaciers in the world, however, are more sensitive to temperature than to other climatic factors

  • Human activity is playing an increasing role in the melting and loss of glacier mass too. Human interference with the forcing of the climate system as people continue to pump greenhouse gases into the air from burning fossil fuels.If greenhouse gas emissions continue to rise at their current rate no doubt on losing them, let’s hope to cut emissions and limit global temperature rise.
  • Evidence suggests that the Earth's average temperature is becoming warmer. Because atmospheric warming will be most readily apparent in the melting glaciers and snow across the Hindu Kush Himalaya(HKH) and they are important indicators of climate change.
