Pollen records from Siberia are mostly absent in global or Northern Hemisphere synthesis works. Here we present a taxonomically harmonized and temporally standardized pollen...

Stable oxygen isotope records from central Greenland suggest disproportionally large long-term surface-air temperature (SAT) variability during the last glacial maximum (LGM)...

This dataset contains PISM simulation results of the Antarctic Ice Sheet based on code release v1.0-paleo-ensemble (https://doi.org/10.5281/zenodo.3574033). PISM is the...

Three time-slice carbon-cycle simulations for the last glacial maximum (LGM) constrained by the CO2 concentration in the atmosphere and the amount of carbon stored in the deep...

This archive contains data files for the sediment properties (distribution and grain size) and bedrock geology for the areas covered by North American ice sheets (including...

Beyond ~13.9 cal kBP, the IntCal19 radiocarbon calibration curve is based upon combining data across a range of different archives including corals and planktic foraminifera. In...

We present here the first results, for the preindustrial and mid-Holocene climatological periods, of the newly developed isotope-enhanced version of the fully coupled Earth...

We provide a climatic data set of the history of annual mean surface air temperature (SAT) over the last 1,000,000 years. The SAT (i.e. the temperature at 2 meter height above...

This data set contains carbon cycle simulations results and estimates of the 14C production rate Q over the last 55,000 years, as well as some not yet online available...

In this study, we used MITgcm-REcoM2 to simulate the stepwise glacial-interglacial atmospheric pCO2 change. A general description of the model can be found in the supporting...

Before conducting grain-size analysis, we treated 36 samples with hydrogen peroxide (30%), set on a platform shaker for 4–5 weeks to remove organic matter, while keeping the pH...

To gain a composite core record for core PG2208 (Figure 1) we used XRF data, i.e., Sr, to correlate overlapping parts of retrieved sections resulting in 367 cm in total. For...

To analyze the mineralogical composition of sediments we freeze-dried and milled 19 samples for X-ray diffractometry (XRD) using a PHILIPS PW1820 goniometer (40 kV, 40 mA, from...

To gain information on organic matter variability we analyzed 204 samples for total carbon (TC) and nitrogen (N), 190 samples for total organic carbon (TOC), 45 samples for...

We compiled new 160 kyr-long mono-specific stacks of changes in both δ13C and δ18O from either the planktic foraminifera G. ruber (rub) or T. sacculifer (sac) from 112 and 40...
