Little Ice Age climate reconstruction from ensemble reanalysis of Alpine glacier fluctuations
Mountain glaciers sample a combination of climate parameters – temperature, precipi-tation and radiation – by their rate of volume accumulation and loss. Flow dynamics actsas transfer function which maps volume changes to a length response of the glacier ter-minus. Long histories of terminus positio...
