Glaciers and Polar Ice Caps

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 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.

A number of films on climate change are available on the Centre for Science and Environment (CSE) store. These include:

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.

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".
