Plio-Pleistocene climate record on the Tibetan plateau
Supplementary Data 1. Results of carbonate (CaCO3) content and carbonate stable isotopes including oxygen (δ18Oc), carbon (δ13Cc), and clumped isotopes (Δ47), as well as grain size and a suite of organic proxies including total nitrogen (TN), total organic carbon (TOC), carbon to nitrogen ratios (C/N), and carbon isotope ratios in organic matter (δ13Corg). Clumped isotopes raw data, cross plots of δ18Oc and ∆47-based temperature, calculations related to mean annual air temperature calculation (MAAT), and surface uplift estimate are also included.
Supplementary Data 2. Estimate of mean annual air temperature (MAAT) using a different temperature-∆47 calibration for comparison.
Supplementary Data 3. Calculation of permafrost thawing area and carbon release.
