Resolving climate change in the period 15–23 ka in Greenland ice cores: a new application of spectral trend analysis
Abstract Northern Hemisphere climate history through and following the Last Glacial Maximum is recorded in detail in ice cores from Greenland. However, the period between Greenland Interstadials 1 and 2 (15–23 ka), i.e. the period of deglaciation following the last major glaciation, has been difficu...
