Short summary
In general, it is not easy to reconstruct past climate variations over a wide band of frequencies using a single proxy. Here, we propose a new method to reconstruct past summer climate seamlessly from annual to millennial timescales by integrating tree-ring cellulose oxygen and hydrogen isotope ratios. The result can be utilized to investigate various scales of climatological phenomena in the past and climate–society relationships in long human history.
