Sentences with phrase «total glacier mass»

Projections for global average temperatures relative to 1850 - 79 (upper chart), rates of glacier change (middle) and total glacier mass (lower chart) for the 21st century.

Not exact matches

As a result, the coastal ice caps and glaciers lose their melting ice as run off 65 percent faster than they can recapture it — contributing to a loss of ice equivalent to roughly 14 percent of the total mass of Greenland.

Rising global temperatures have also made glaciers — ice masses that currently occupy nearly 10 percent of the world's total land area — increasingly unstable.

A total of over 5,000 measurements of glacier volume and mass changes since 1850 and more than 42,000 records from observations and reconstructions dating back to the sixteenth century were analyzed.

The estimated 2010 or 2011 surface mass imbalance (~ 300 Gt / yr) is comparable to the GRACE estimates of the total mass loss (which includes ice loss via dynamic effects such as the speeding up of outlet glaciers) of 248 ± 43 Gt / yr for the years 2005 - 2009 Chen et al, 2011.

According to BBC Brasil, between 1993 and 2003 alone, Trento's Presena glacier lost as much as 39 percent of its total mass.

Although one can point to particular glaciers that are growing, glaciologists look for trends in the total mass of glaciers worldwide.

Annual net balance on eight North Cascades glaciers during the 1984 - 1994 period has been determined by measurement, of total mass loss from firn and ice melt and, of residual snow depth at the end of the summer season.

We had the advantage of already understanding the overall mass balance pattern of each glacier in selecting measurement networks that would provide the most representative coverage for the glacier given the total number of measurements in each sample (Pelto, 1996; Miller and Pelto, 1999).

The total global ice mass lost from Greenland, Antarctica and Earth's glaciers and ice caps during the study period was about 4.3 trillion tons (1,000 cubic miles), adding about 0.5 inches (12 millimeters) to global sea level.

The limited resolution of GRACE affects the uncertainty of total mass loss to a smaller degree; we illustrate the «real» sources of mass changes by including satellite altimetry elevation change results in a joint inversion with GRACE, showing that mass change occurs primarily associated with major outlet glaciers, as well as a narrow coastal band.

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.

► Mean specific mass balance: The total mass balance per unit area of the glacier.

Pritchard points out that basal melt is a control on total mass waste ``... through a reduction in buttressing of the adjacent ice sheet leading to accelerated glacier flow.»
