The δ2H signature of lignin methoxyl groups of tree-ring sections was investigated.
- class="label">•
In the mid-latitudes the δ2H signature reflects the annual δ2H of precipitation.
- class="label">•
Modern mean annual temperatures could be closely predicted using the δ2H signature.
- class="label">•
The results are discussed in context of their paleoclimate relevance.
