Abstract

Physical readjustments involved in glacier fluctuations present high risk situations at certain times and places. An outline of the history of glacier fluctuations in Holocene times and particularly the Little Ice Age provides the context for a discussion of the types of hazards associated with climatically led oscillations in populated areas and their timing. The threat from such glaciers has diminished but not disappeared with the recession of the last century. The impact of the more dramatic oscillations of surging glaciers and those with floating tongues has been limited by their restricted spatial distribution. Increased penetration of economic development into hitherto remote mountain regions and escalation of the numbers of people involved in sports such as skiing and mountaineering increase glacier hazard. Any future change in climate towards the conditions obtaining in the Little Ice Age would now involve greater risk from hazard than existed in former centuries. A more probable change in climate is rising temperature caused by more carbon dioxide in the atmosphere resulting in rising sea levels and perhaps surging of the Antarctic icesheet.
