Plio-Pleistocene climate record on the Tibetan plateau (4.3 Ma to 0.8 Ma).

Supplementary Data 1. Results of carbonate (CaCO₃) content and carbonate stable isotopes including oxygen (δ¹⁸O_c), carbon (δ¹³C_c), 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 (δ¹³C_org). Clumped isotopes raw data, cross plots of δ¹⁸O_cand∆_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.

Supplement to Cheng F. et al., Alpine permafrost could account for a quarter of thawed carbon based on Plio-Pleistocene paleoclimate analogue, Nature Communications.
