Fig. 2: Moisture evolution during the last 5 Ma based on the stable isotopic record of Charyn Canyon sequence.
From: Central Asian modulation of Northern Hemisphere moisture transfer over the Late Cenozoic

a–c Charyn Canyon sedimentation rate (mm ka−1); δ13Cpc and δ18Opc values and clumped isotope temperatures (red squares, T∆47) respectively (gray shading: 1σ error for stable isotope ratios). d, e SST data from ODP 60755 and ODP 98281 respectively. Red lines represent moving averages (five points for Charyn Canyon and 20 points for the marine cores); dashed lines divide the main phases (1−4) discussed in the text. MPT Mid-Pliocene transition; MIS M2 marine isotope stage M2 (3.3−3.2 Ma).
