In all of these simple models, we assume the atmosphere to have a volume as fixed as a bathtub, we assume that the atmosphere / ocean system is a closed system, we assume that the incoming radiation from the Sun is constant, we assume no turbulence, we assume no viscosity, we assume radiative equilibrium with no feedback lag, we take no account of water vapor flux assuming it to be constant, no change in albedo from changes in land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetatioIn all of these simple models, we assume the atmosphere to have a volume as fixed as a bathtub, we assume that the atmosphere / ocean system is a closed system, we assume that the incoming radiation from the Sun is constant, we assume no turbulence, we assume no viscosity, we assume radiative equilibrium with no feedback lag, we take no account of water vapor flux assuming it to be constant, no change in albedo from changes in land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetatioin albedo from changes in land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetatioin land use, glacier lengthening and shortening, no volcanic eruptions, no feedbacks from vegetation.

To say nothing of the warming trends also noticed in, for example: * ocean heat content * wasting glaciers * Greenland and West Antarctic ice sheet mass loss * sea level rise due to all of the above * sea surface temperatures * borehole temperatures * troposphere warming (with stratosphere cooling) * Arctic sea ice reductions in volume and extent * permafrost thawing * ecosystem shifts involving plants, animals and insects

In the period 1992 to 2005, the glacier suffered a loss of 90 % of its surface area, and 97 % of its volume of ice (Berger et al., 2005).

Hence the above velocity map of the glacier will indicate higher average velocities in the quadrants with the highest calving volume flux.

This latter assumption may need to be adjusted if glaciers and ice caps in the Eocene had a volume of tens of metres of sea level.

North Cascade glaciers annual balance has averaged -0.54 m / a of water equivalent from 1984 - 2006, a cumulative loss of over 12.4 m in glacier thickness or 20 - 40 % of their total volume since 1984 due to negative mass balances.

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.

Through a combination of direct satellite observations and modeling, they determined the total volume of ice tied up in the glaciers is nearly 41,000 cubic miles (170,000 cubic kilometers), plus or minus 5,000 cubic miles (21,000 cubic km).

Record droughts in many areas of the world, the loss of arctic sea ice — what you see is an increasing trend that is superimposed on annual variablity (no bets on what happens next year, but the five - to - ten year average in global temperatures, sea surface temperatures, ocean heat content — those will increase — and ice sheet volumes, tropical glacier volumes, sea ice extent will decrease.

The difference between the accumulation and ablation for a given year describes the annual net mass balance, which corresponds to the change in glacier thickness and volume.

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.

As many people are aware (and as John Nieslen - Gammon outlined in a post last month and Rick Piltz goes over today), there is a statement in the second volume of the IPCC (WG2), concerning the rate at which Himalayan glaciers are receding that is not correct and not properly referenced.

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 203In 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 203in 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.

This is of course not the proper IPCC projection of future glacier decline, which is found in Volume 1 of the report.
