Although Zwally calculated the net «mass gains from snow accumulation exceeded losses from ice discharge by about 112 and 82 Gt / year respectively during the 1992 - 2001 and 2003 - 08 measurement periods», he also reported that the rate of ice loss along the west Antarctic coast and the peninsula had increased from 64 GT / year to 135 GT / year during those same periods.

Long - term climate warming is strongly correlated with declining snow water equivalent and shifts in stream flow throughout the American West and appear to be largely explained by decreased spring accumulation and / or increased spring melt.

Scientists: Warming causes Antarctic ice sheet growth, and lower sea levels By Kenneth Richard While many scientists are projecting rapid sea level rise as a result of a warmer Antarctica and consequent ice sheet melting, other scientists are projecting that the surface of the Antarctic ice sheet will gain in mass because a warmer Antarctica means snow and ice accumulation will outpace the -LSB-...]

Glaciochemical and particulate data record atmospheric - loading changes with little uncertainty introduced by changes in snow accumulation.
