Fig. 2. A) 230Th ages, StalAge model uncertainty, δ18Oca and δ13Cca values of GI-I (MIS 5e) of Y99. B) Box-whisker plot comparison of Hoti Cave (Oman) and Mukalla Cave (Yemen) stalagmite δ18Oca values from Fleitmann et al. (2011) and Nicholson et al. (2020). Numbers above and below box-whiskers indicate amount of δ18Oca measurements and speleothem samples, respectively. The yellow bar denotes the range of modern δ18O values in Oman, derived mostly from winter rainfall.
