Glacier lake outburst floods: Wrecking havoc to life and property in the Himalayan region
A glacier lake outburst flood (GLOF) is caused when the glacial lakes burst their banks and cause widespread floods. In the past two decades there have been a number of glacier lake outburst floods. The increase in the melting of glaciers have led to this phenomenon. Posted on 26 Aug, 2009 03:47 PM

These floods cause havoc with human life, flora and fauna of the area and the infrastructure in the region.

The Dig Tosho Glacier lake outburst in August 1985, destroyed the nearly completed Namche hydropower plant and all the rails, roads, and other infrastructure in its course.

How climate change has affected Ladakh: The region has seen unusual floods in July 2005 and August 2006
Ladakh is known as the cold-desert and has severe conditions and is barren and arid. The region has seen unusual floods in July 2005 and August 2006. Posted on 26 Aug, 2009 03:36 PM

It is in Jammu Kashmir and is bordered by the Himalayas and the Karakoram mountain chains. Ladakh and its water sources are almost entirely dependent on the glaciers and snow-melts and changes in water systems can be directly attributed to changes in the glaciers and thus climate change.

Impact of climate change on the Himalayan glaciers
40% reduction has occurred in the Himalayan glaciers in the last 40 years. 67% of the glaciers have retreated in the last decade. Gangotri is retreating at the rate of 28 m per year. Global warming and its consequent melting of glaciers would result in floods, fast and furious run-offs, erosion of the topsoil and sedimentation of the rivers. This could also lead to changes in the course of the rivers in the region. Posted on 26 Aug, 2009 03:30 PM

The Himalayas' permanent ice cover is around 97,000 sq.km. with 12,930 sq.km. volume of ice and snow: 10-20 % are covered by glaciers and 30-40% are seasonal snowfalls. The Himalayan streams and rivers are fed by the melting of snow and ice of approximately 500 sq.km / year.

How changing climate and melting glaciers affects nations across the globe: Spotlight on the Himalayas
In the next decade, the Himalayas are projected to suffer from devastating Glacial Lake Outburst Floods (GLOFs) and landslides - Is climate change the culprit? Posted on 25 Aug, 2009 05:11 PM

As observed by the United Nations Environment Program (GRID-Arendal) ice and snow are major components of the climate system. That is why human induced climate change can be first observed in Polar Regions where most of Earth's snow and ice are concentrated. In these areas global warming induces the progressive melting of ice and snow.

The many impacts of climate change - A serious global environmental issue?
Climate change due to the increasing concentration of GHGs in the atmosphere since pre-industrial times poses a huge threat and challenge to mankind. Posted on 25 Aug, 2009 03:14 PM

The earth is currently warming rapidly. And this warming is bringing about massive changes. Our glaciers are melting rapidly. The artic ice-shelf is breaking apart into pieces and threatens to modify the salinity of the oceans.

Preliminary consolidated report on the effect of climate change on water resources, prepared by the Central Water Commission and the National Institute of Hydrology, under the guidance of the Ministry of Water Resources in 2008
This is one of the first official reports made available by the Government of India, of a reliable quantitative assessment based on field data Posted on 05 Jan, 2009 11:22 AM

The Preliminary Consolidated Report on the Effect of Climate Change on Water Resources, prepared by the Central Water Commission and the National Institute of Hydrology, under the guidance of the Ministry of Water Resources in 2008, is one of the first official reports made available by the Government of India, of a reliable quantitative assessment based on field data, of the likely effect of climate change on the availability of water resources, i.e. on the glaciers and snow melt, on rainfall and their effect on run off into the river system and their contribution to ground water. In the Report, an attempt has been made to give a brief account of the available studies on possible impacts of climate change on India's water resources, change in India's water needs, climate of India, river basins of the country, present water resources and future demand and supply, impacts of projected climate change and variability, and associated hydrological events and likely vulnerability of regional water resources to climate change. Identification of key risks, research needs and prioritisation of mitigation strategies has also been discussed.

Himalayan glaciers 'decapitated' ? Alarming climate change news
Himalayan glaciers 'decapitated' ? Alarming climate change news Posted on 27 Nov, 2008 11:17 AM

A 'major new study' brings alarming news that the Himalayan glaciers are melting at a faster rate than earlier estimated. A study of the Naimona'nyi Glacier in Tibet found that "the glacier had melted so much that the exposed surface of the glacier dated to 1944".
