The isotopic climatic records in the Alleröd-Bølling-Younger Dryas and Post-Younger Dryas events
The combined isotopic records in the Greenland ice cores, in modern and ancient wood samples, and in marine foraminifera provide a climatic record for the Alleröd-Bølling-Younger Dryas and post-Younger Dryas Periods that is not compatible with the usual climatic interpretation of the ^2H/^1H ratio...
