The paleoclimatic record from a 345 m long ice core from the Hans Tausen Iskappe
The 345 m long ice core retrieved from the Hans Tausen Ice Cap in 1995 (82,5°N, 38°W) in Western Peary Land was sampled in situ for later paleoclimatic δ18Omeasurements in Copenhagen. The upper 125 m covers a little more than 1000 years and indicates strong persistent warming from the late 1920-ties...
