Some polar areas currently undergo a warming faster than the global average. We show this recent trend as well as the estimates regarding the evolution of glaciers and ice caps mass balance. These variations are discussed in the framework of natural climate variations at both poles, using the oldest ice cores available and spanning more than 120 000 years in Greenland (NorthGRIP deep drilling) and 800 000 years in Antarctica (EPICA Dome C deep drilling).
