“…The pollen records in the desert-loess transition zone indicate that precipitation and humidity increased gradually during this time, and pollen species and deciduous broad-leaved trees such as Betula and Corylus as well as some aquatic herbs were common. However, terraneous herbs such as Artemisia and Chenopodiaceae were the dominant species during this stage (J Zhang et al (2019), Camuera et al (2019)). This relatively warm and humid climate prevailed in much of China during this time (Fan et al (2019)).…”

Detailed organic carbon isotope (δ 13 C org) measurements were conducted on two peat sequences recovered from the north bank of the Yangtze River, East China. Seven radiocarbon dates provided firm age control of this δ 13 C org record and reveal palaeoclimatic changes since the Late Glacial period. The results show that the Holocene Megathermal Maximum occurred between 8385 and 7040 cal. yr BP. The Late Glacial climate was generally cold but fluctuated frequently between 12940 and 11815 cal. yr BP. The Older Dryas (from 12940 to 12810 cal. yr BP) and the Younger Dryas (from 12645 to 12170 cal. yr BP) were characterised by cold climate conditions. In contrast, 12810 to 12645 cal. yr BP (corresponding to the Allerød Warm Period) and 12170 to 11815 cal. yr BP (corresponding to a rapid warming period after the Younger Dryas, marking the beginning of the Holocene) were relatively warm phases. In contrast to other high-resolution records, it shows that the δ 13 C org records of our study peats are largely controlled by a common forcing mechanism of solar insolation changes in the Northern Hemisphere, and exhibit similar variability to δ 18 O records obtained from stalagmites and GISP2 during the Late Glacial and early-mid Holocene.

“…Supporting the latter, paleoglaciological reconstructions argue for significantly more extended ice cover in the Dinarides and Hellenides in the MIS 6 compared to MIS 2 [118,119] suggesting more humid conditions. Paleoglaciological and paleobiological evidence argue for a similar MIS 2 vs. MIS 6 contrast regarding hydroclimate in the western Mediterranean (e.g., [120]). This hydroclimatological contrast might be partially reflected in speleothem isotopic records.…”

Speleothem Records from the Eastern Part of Europe and Turkey—Discussion on Stable Oxygen and Carbon Isotopes

The region comprising of East Central Europe, South East Europe and Turkey contributed to the SISAL (Speleothem Isotopes Synthesis and AnaLysis) global database with stable carbon and oxygen isotope time-series from 18 speleothems from 14 caves. The currently available oldest record from the studied region is the ABA-2 flowstone record (Abaliget Cave; Hungary) reaching back to MIS 6. The temporal distribution of the compiled 18 records from the region points out a ~20 kyr-long period, centering around 100 ka BP, lacking speleothem stable isotope data. The regional subset of SISAL_v1 records displays a continuous coverage for the past ~90 kyr for both δ13C and δ18O, with a mean temporal resolution of ~12 yr for the Holocene, and >50 yr for the pre-Holocene period. The highest temporal resolution both for the Holocene and the pre-Holocene was achieved in the So-1 record (Sofular Cave; Turkey). The relationship between modern day precipitation δ18O (amount weighted annual and winter season mean values; 1961–2017) and climatological parameters was evaluated. The strong positive correlation found in East Central Europe reinforces the link between modern day precipitation δ18O, temperature and large-scale circulation (North Atlantic Oscillation) expected to be preserved in the speleothem δ18O record; while a negative relationship was documented between precipitation amount and oxygen isotope compositions in South East Europe. Variations of δ13C values are primarily interpreted as reflecting dry/wet periods across the region. Elevation gradients from three non-overlapping periods of the last ~5 kyr indicated elevation gradients around −0.26‰ per 100 m−1 for calcite δ18O.

“…We thoroughly agree that it would be good to plug the gaps, and this will be an effort for the future. The three papers that we cite at lines 361-363 (Flantua et al, 2015;Herbert and Harrison, 2016;Harrison et al, 2016) demonstrate that there are pollen records available that would plug the gaps, but alas do not provide quantitative reconstructions at these sites. The Izumi and Bartlein, 2016 paper provides an inversion-based reconstruction for North American -this region is already relatively well covered in the Bartlein et al data set.…”

We thank the reviewer for their positive and helpful comments on our manuscript. 1) As the reviewer points out, the pollen-based reconstructions and the climate model simulations underpinning our reconstruction are in the public domain, and the data assimilation methodology is described in detail in another publication. The general approach used for the CO2 corrections, which the reviewer describes as a significant contribution, was published in Prentice et al. (2017) -although we provide the equations for the implementation of this approach in the current paper in Appendix 1. Therefore, the new results in this paper are indeed the global maps of reconstructed climate variables. These data are archived and will be made publicly available -however, we C1 CPD Interactive commentPrinter-friendly version Discussion paper
