Global Warming: Over 70 per cent of Everest glacier’s volume may be lost by 2100

New Delhi: Over 70 per cent of the glacier volume in the Mount Everest region in the Himalayas could be lost in 85 years if greenhouse gas emissions continue to rise, a new paper suggests. It also indicates more flood risk in the future in the Kosi river downstream from Nepal to India.

The paper, “Modelling glacier change in the Everest region, Nepal Himalaya”, published on Wednesday in The Cryosphere, a journal of the European Geosciences Union (EGU), said the glacier volume could be reduced between 70 and 99 percent by 2100.

It is a first approximation to how the Himalayan glaciers will react to increasing temperatures in the region. The results depend on how much greenhouse gas emissions continue to rise and on how this will affect temperature, snowfall and rainfall in the area.

A team of researchers from Nepal, France and the Netherlands have found the Everest glaciers could be very sensitive to future warming and that sustained ice loss through the 21st century is likely.

If greenhouse gas emissions continue to rise, the glaciers could experience dramatic change in the decades to come, said the study.

“The signal of future glacier change in the region is clear: continued and possibly accelerated mass loss from glaciers is likely given the projected increase in temperatures,” said Joseph Shea, a glacier hydrologist at the International Centre for Integrated Mountain Development (ICIMOD) in Kathmandu.

“Our results indicate that these glaciers may be highly sensitive to changes in temperature and that increases in precipitation are not enough to offset the increased melt,” Shea said.

Increased temperatures will not only increase the rates of snow and ice melt but can also result in a change of precipitation from snow to rain at critical elevations, where glaciers are concentrated. Together, these act to reduce glacier growth and increase the area exposed to melt, said the leader of the study.

The researchers studied glaciers in the Dudh Kosi basin in the Nepal Himalayas, which are home to some of the world’s highest mountain peaks, including Mt Everest, and to over 400 sq km of glacier area.

“Apart from the significance of the region, glaciers in the Dudh Kosi basin contribute meltwater to the Kosi river, and glacier changes will affect river flows downstream,” Shea said.

Changes in glacier volume can impact the availability of water, with consequences for agriculture and hydropower generation.

While increased glacier melt initially increases water flows, ongoing retreat leads to reduced meltwater from the glaciers during the warmer months, with greatest impact for the local populations before the monsoon when rainfall is scarce, said the paper.

Glacier retreat can also result in the formation and growth of lakes dammed by glacial debris. Avalanches and earthquakes can breach the dams, causing catastrophic floods that can result in river flows 100 times greater than normal in the Kosi basin.

The Kosi river is known as the “sorrow of Bihar” as it has caused widespread damage in the past due to flooding and frequent change in its course.

To find out how glaciers in the region will evolve in the future, the researchers started by using field observations and data from local weather stations to calibrate and test a model of glacier change over the past 50 years.

“To examine the sensitivity of modelled glaciers to future climate change, we applied eight temperature and precipitation scenarios to the historical temperature and precipitation data and tracked how glacier areas and volumes responded,” said study co-author Walter Immerzeel of Utrecht University in the Netherlands.

“Our estimates need to be taken very cautiously, as considerable uncertainties remain,” said Patrick Wagnon, a glaciologist at the L’Institut de Recherche pour le Developpement in Grenoble in France.

The paper stresses that “the signal of future glacier change in the region is clear and compelling” and that decreases in ice thickness and extent are expected for “even the most conservative climate change scenario”.

  • Changu Narayan is considered to be the oldest temple in Nepal
  • It is based on a high hilltop know was Changu or Dolagiri
  • It is dedicated to Lord Vishnu and has an interesting tale behind it

New Delhi, July 14, 2017: The ancient Hindu temple Changu Narayan is situated on the top of a high hill well known as Changu or Dolagiri. The temple had a neighboring forest of champak tree and a small village called Changu and is situated in Bhaktapur District, Nepal.

The hill is about 7 miles or 12 km east of Kathmandu and a few miles north of Bhaktapur. This holy place “changu narayan Temple” is devoted to Lord Vishnu and held in admiration by the people of Hindu religion. Changu Narayan is believed to be the oldest temple in Nepal’s history. Bhaktapur king established kingdoms in Kashmir and kept it as Hindu kingdom.

“changu narayan Temple” has a very intriguing story behind its existence. In old times, a Gwala, a cow herder, was given a cow by a Brahmin whose name was Sudarshan. The cow was believed to produce milk in large quantities. The cow herder used to take the cow for grazing to Change, which was a Champak trees forest that time. The cow was always found under a particular tree’s shade while grazing. In the evening, when the Gwala started milking the cow at his house, he received only a negligible quantity of milk. This continued for a number of days. He was disappointed and told the Brahmin about the cow not giving enough quantity of milk. After seeing this incident with his eyes, Sudarshan agreed and they decided that they should examine the cow while her grazing activity was being undertaken.

Both of them hid behind the trees and observed the cow. They noticed that a small black boy who had come out of the tree started feeding himself with the milk. This infuriated the two men as they thought of the boy as a demon and the tree as its home.

So the champak tree was cut down by the Brahmin. While he was doing this, he saw human blood come out of the champak tree. Both Brahmin and Gwala presumed they had done a crime and started crying.

Lord Vishnu suddenly emerged and told the Gwala and Brahmin, the mistake was not theirs and began narrating the story of him committing a crime by unknowingly murdering Sudarshan’s father while forest hunting. Afterward, he was cursed and he wandered on his mouth, as ‘Garuda’ descending on the Changu hill where he survived on stolen milk. The cutting down of the tree by Brahmin beheaded Vishnu and freed him from his sins.

Following this incident, Brahmin and Gwala started worshiping that place and built a small temple of Lord Vishnu. That place has been considered sacred ever since. Even today, Sudarshan’s descendant is one of the priest of that temple and the Gwala’s descendants as conservators.

People belonging to Newar community reside in and around the area of Changu Narayan. Due to tourism development in this area, we can locate many hotels, souvenir shops, restaurants etc.

However, this holy temple “changu narayan” faces a lot of challenges and threats. The Manohara stream has witnessed rampant mining of sand and stones. The local administration has failed to cut down the mining activities. Due to these mining activities, the temple area has become prone to landslides. Because of overgrazing in the nearby forest, the chances of soil erosion and landslide have become very high.

  • Floods in India, Nepal and Bangladesh have claimed more than 1,300 lives in the last two months
  • According to UNICEF, over 16 million children in the three countries are in urgent need of life-saving support
  • Persistent rainfall has damaged school infrastructure, apart from depriving children of safe places to stay at, and necessities like drinking water and food

New Delhi, September 4, 2017 : Hurricane Harvey created havoc in Houston in August, claiming 15 lives and displacing tens of thousands of people. The event was largely covered by national and international media alike, keeping people abreast with the latest updates. However, the floods in South Asia, which are equally devastating, are yet to receive due coverage from international media. According to data released by UNICEF, the unusually heavy monsoon over the last several weeks has claimed more than 1,300 lives across India, Nepal and Bangladesh.

In its entirety, over 45 million people have suffered the direct impact of the rains and its resulting floods.

Floods in South Asia

For over two months, incessant rains have submerged numerous villages thereby forcing vast numbers of people into evacuation centers and relief camps.

According to a UN Agency report, over 16 million children residing in India, Nepal, and Bangladesh are in dire need of life-saving support due to weeks of torrential monsoons that have given rise to ‘catastrophic’ floods in the three South Asian countries.

UNICEF Regional Director for South Asia, Jean Gough noted that millions of children have already been affected by these devastating floods as incessant rains continue to pose potential threat.  “Children have lost their homes, schools, and even friends and loved ones. There is a danger the worst could still be to come as rains continue and flood waters move south,” she added, according to a report by PTI.

According to official figures, at least 1,288 deaths have been reported since mid-August.

Gough believes the persistent rainfall and the resulting water accumulation have damaged school infrastructure among other things which will hamper children from attending classes for weeks, or even months. According to her, “Getting children back into school is absolutely critical in establishing a sense of stability for children during times of crisis and provides a sense of normality when everything else is being turned upside down”

Among other urgent needs of these children are clean drinking water, sufficient food supplies, hygiene supplies to control and combat the spread of potential diseases and safe evacuation places for the children to stay at, study and play.

Devastation from floods in India

According to a report by PTI, in the northern part of the country, over 31 million people have been affected in four states due to the extensive flooding. Out of this, 12.33 million sufferers are believed to be children.

The tally of houses damaged by the floods has reached 805,183 while 15,455 schools have been damaged, that has disrupted the education of children.

Additionally, the heavy downpour in Mumbai has already claimed five deaths due to drowning while twelve people, including two children have died due to the collapse of a building.

Rescue operations are being undertaken in these states by their respective state governments, which include carrying out relief, recovery and rehabilitation operations.

Furthermore, the state governments have also sought multi-sectoral planning and coordination support from UNICEF in the three worst affected states. These include Bihar, Assam and Uttar Pradesh.

Devastation from floods in Bangladesh

According to Oxfam, with the rising water levels, the flooding is believed to be the worst since 1988 with nearly two-thirds of the country currently submerged under water.

More than 8 million people are reported to have been hit by the floods in Bangladesh, out of which 3 million are allegedly children. Primary and community educational institutions across the country have been terribly hit with as many as 2,292 schools reportedly damaged by the high water.

The country has also reported over 13,035 cases of water-borne diseases.

Devastation from floods in Nepal

Floods in Nepal have displaced 352,738 people from their homes, thus, affecting over 1.7 million people. The water has reportedly surfaced to dangerous levels, to escape which people are making use of makeshift rafts and elephants for rescue operations.

According to a report by PTI, damage to nearly 1,958 schools has affected the education of over 253,605 children.

Major media giants across the world are pledging their support to help combat the scale of  destruction.

In a blog post, Google Vice-President of South East Asia and India wrote, “We are committing $1 million from Google.org and Google employees to Goonj and Save the Children for their relief efforts.”

The NGO, Goonj aims to offer assistance to over 75,000 affected families across India and provide them with basic needs like food, blankets and hygiene supply while on the other hand, Save the Children is focused on setting up child-friendly public spaces for the children to have access to educational material.

Similar organizations have taken up an active role to help rebuild infrastructure for the community like roads, bridges and physical infrastructures.

What causes floods in South Asia?

Apart from the high magnitude of rainfall received this year, the floods in south Asia are believed to have been aggravated by human actions such as reckless construction on floodplains and in the coastal areas, waterways clogged by garbage and a faulty drainage system

According to a report published by VOA, experts have pointed out the inefficiency of the governments of the three countries and have said that is has become increasingly evident that the South Asian governments were unprepared for the annual monsoon showers.

However, disaster management officials also assert that it will be unfair to criticize the governments in view of the magnitude of the floods this year.
