Hydrogen isotope ratios (δD) in various types of leaf waxes, including n-alkanoic acids, extracted from lacustrine sediments are becoming increasingly popular for understanding past climate changes. Leaf-wax δD values track precipitation δD, and provided that controls on precipitation δD are known,...
