Their projections show a reduction of about 70 % in
glacier volume by the year 2100 compared to 2005, with the largest losses occurring around 2020 to 2040.

Yesterday's study suggests that total
glacier volume across all the investigated basins will decrease
by about 43 percent
by the year 2100, even if the world takes serious steps to mitigate climate change.
For instance, if global warming were to increase the
volume of water in the oceans
by causing
glaciers or other ice bodies to melt, this would cause the weight of water in the oceans to increase.
Glaciers change the strength of the skin rather than the contained
volume, but the mechanical effect on the strength of the structure is the same How thick is the skin of a rocket booster held rigid
by pressure of the fuel inside?
The IPCC projections of sea level rise are based largely on the slow, steady and inexorable thermal expansion of the oceans (as water heats, its
volume increases) with some additional contributions from the melting of mountain
glaciers (almost all of which are expected to be gone
by mid century).

The «second order» review draft of the SPM for the Working Group II
volume said «If current warming rates are maintained Himalayan
glaciers could decay at very rapid rates, shrinking from the present 500,000 km2 to 100,000 km2
by the 2030s.»
They are limited only
by the amount of water the
glaciers themselves release — ice masses that hold
volumes of water often measured in cubic kilometers.
The Hindu: «The Gangotri
glacier is retreating like other
glaciers in the Himalayas and its
volume and size are shrinking as well,» a report, titled «Estimation of retreat rate of Gangotri
glacier using rapid static and kinematic GPS survey»,
by scientists from the Almora - based G.B. Pant Institute of Himalayan Environment and Development has stated.
An international team led
by glaciologists from the University of Colorado Boulder and Trent University in Ontario, Canada has completed the first mapping of virtually all of the world's
glaciers — including their locations and sizes — allowing for calculations of their
volumes and ongoing contributions to global sea rise as the world warms.
They determined, however, that this
volume had now increased
by a further 3 cubic miles each year, prompted
by an acceleration in the rate at which the ice caps and
glaciers are melting.Unlike what many other scientists have said — including, most prominently, NASA's James Hansen (who believes that a rise in 17 inches
by 2100 will be mainly precipitated
by the melting of ice sheets)-- the authors of this study believe that the loss of ice from
glaciers and ice caps will account for the majority of the expected rise in sea levels.
For example, analyses of
glacier mass balances,
volume changes and length variations along with temperature records in the western European Alps (Vincent et al., 2005) indicate that between 1760 and 1830,
glacier advance was driven
by precipitation that was 25 % above the 20th century average, while there was little difference in average temperatures.
Himalayan
glaciers: In a regional chapter on Asia in
Volume 2, written
by authors from the region, it was erroneously stated that 80 % of Himalayan
glacier area would very likely be gone
by 2035.
That is, I found the sources of the mistaken claim, made in the second
volume (section 10.6.2) of the IPCC's Fourth Assessment, that Himalayan
glaciers are very likely to disappear
by 2035 or perhaps sooner.
