RESPONSE OF NEW ZEALAND GLACIERS TO THE CLIMATE EVENTS OF THE LITTLE ICE AGE: A TEMPLATE FOR OLDER CLIMATE CHANGES?
At temporal scales longer than a few decades these patterns are consistent with the behavior of glacial systems across the Northern Hemisphere and with paleo-climate reconstruction of the latter part of the Little Ice Age. When carefully considered then, glacial systems should provide key insights about climate changes in the more distant past. Some considerations are 1) the dominate signal from glacial landforms/ sediments is deglaciation responding to increased ablation, cooling signals are contained within the timing of advances events. 2) multiple systems must be compiled to counter the likelihood that any specific sequence my not contain all expansions, and 3) the climate signals should be of the magnitude of the Little Ice Age or larger to overcome the influence of local meteorological/ glaciolgical conditions.
