Abstract

IT is well established that climatic fluctuations which are global or hemispheric in extent are most pronounced in high northern latitudes, particularly around the North Atlantic1–4. Recent evidence also suggests that certain sectors of the Arctic are extremely sensitive to small climatic shifts and as a result may undergo visible changes in the landscape5–7. Here I report on an analysis of upper air data for the Canadian Arctic archipelago which indicates that marked changes in freezing level heights have occurred during the past two decades as a result of changes in atmospheric circulation across the area.
