global glacier state

What is the current state of glaciers around the world?
Glaciologists assess the state of a glacier by measuring its annual mass balance as the combined results of snow accumulation (mass gain) and melt (mass loss) during a given year. The mass balance reflects the atmospheric conditions over a (hydrological) year and, if measured over a long period and displayed in a cumulative way, trends in mass balance are an indicator of climate change. Seasonal melt contributes to runoff and the annual balance (i.e. the net change of glacier mass) contributes to sea level change.
