"Understanding the non-climatic controls on the behavior of calving glaciers is an important problem if we want to use the historic and contemporary record of change of calving glaciers as indicators of climate change. And this problem is especially important in Patagonia where almost all of the outlet glaciers are (or were until recently) actively calving into fiords or freshwater lakes."
They don't want to tell us about the growing glaciers.
