Cuticle analysis performed on fossil Betula nana (L.) leaves provides a strong proxy to reconstruct past growing season thermal properties expressed as growing degree days (GDD 5 ). This proxy is so far available for the dwarf birch only and, therewith, restricted to regions or past periods of subar...
