Short summary
We examined annually resolved stable carbon and hydrogen isotope ratios of wood lignin methoxy groups of beech trees growing in temperate, low elevation environments. Here, carbon isotope ratios reveal highest correlations with regional summer temperatures while hydrogen isotope ratios correlate more strongly with large-scale temperature changes. By combining the dual isotope ratios of wood lignin methoxy groups, a proxy for regional- to subcontinental-scale temperature patterns can be applied.
