Were last glacial climate events simultaneous between Greenland and France? A quantitative comparison using non‐tuned chronologies
Abstract Several large abrupt climate fluctuations during the last glacial have been recorded in Greenland ice cores and archives from other regions. Often these Dansgaard–Oeschger events are assumed to have been synchronous over wide areas, and then used as tie‐points to link chronologies between t...
