Here we present an ice core oxygen isotope record from the continental Siberian Altai, serving as a high-resolution temperature proxy for the last 750 years. The strong correlation between reconstructed temperature and solar activity suggests solar forcing as a main driver for temperature variations during the period 1250-1850 in this region. The precisely dated record allowed for the identification of a 10-30 year lag between solar forcing and temperature response, underlining the importance of indirect sun-climate mechanisms involving ocean-induced changes in atmospheric circulation. Solar contribution to temperature change became less important during industrial period 1850-2000 in the Altai region. STUDY NOTES: Ice core oxygen isotope data (d18O) and March-November temperature reconstruction for the Altai region of Siberia over the past 750 years. Marc-November temperatures in the Altai region were reconstructed using d18O measurements from a Belukha ice core in the Siberian Altai. Dating uncertainties are <3 years (AD 1815-1980), <5 years (AD 1400-1815), and <10 years (AD 1250-1400). Calibration was performed for the period 1850-1980 based on 10-year means, using temperature data from the weather station Barnaul.
