Abstract
Ice core records from polar regions are of great value to study longterm climate and environmental change Greenland icecore records are celebrated for their high resolution and have provided very important knowledge for understanding the late Quaternary palaeoclimate especially in reference to millennialscale abrupt climatic flips during the last glaciation Recently a new project to retrieve a deep icecore from Greenland known as NEEM for North Greenland Eemian Ice Drilling has been launched with the main target being the last interglacial period The new core will help us understand further details of climate changes during a period of warmth as the present Antarctic ice cores have a unique advantage in providing recovery of longer timescale paleclimate information and hence are regarded as a crucial pillar to examine climatic cycles on the timescale of Earthorbital phenomena Since the bottom ice in Dome A is estimated to be older than a million years a deep drilling there becomes a new focus for ice core studies
