Non-polar glacial ice holds a wealth of information about past
changes in climate, the environment and especially
atmospheric composition, such as variations
in temperature,
atmospheric concentrations of greenhouse gases and emissions of natural aerosols or human - made pollutants... The glaciers therefore hold the memory of former climates and help to predict
future environmental
changes.
Changes in atmospheric composition and chemistry over the past century have affected, and those projected into the
future will affect, the lifetimes of many greenhouse gases and thus alter the climate forcing of anthropogenic emissions:

in future decades: Determining the relative impacts of
changes in climate, emissions, global
atmospheric composition, and regional land use.
