Notebook using "Shackleton site" oxygen isotopes over the last 1.5 Ma #9

This is a superb dataset: https://cp.copernicus.org/preprints/cp-2022-61/. When it is publicly released, it would be great to use wavelet analysis to diagnose changes in millennial variability over the length of the record and possible linkage to external factors.

And it could nicely be paired with this simulation:

The IBS Center for Climate Physics, South Korea, recently completed a new transient simulation covering the global climate history of the past 2 million years ago (“2Ma”). This simulation is based on the Community Earth System Model version 1.2 (CESM1.2) in 3.75°×3.75° horizontal resolution forced with estimates of the Northern hemispheric ice sheet distribution,CO2 concentrations and astronomical insolation changes.

The key reference for the simulation is:

Climate effects on archaic human habitats and species successions, Timmermann, K.-S. Yun, P. Raia, J. Ruan, E. Zeller, C. Zollikofer, M. P. de León, D. Lemmon, M. Willeit, A. Ganopolski, Nature, doi: 10.1038/s41586-022-04600-9 (2022).

The supplementary material of our study includes more technical details on the set-up and some comparisons with other paleo-climate data.

Some key datasets from the CESM1.2 2Ma simulation have been made available for further analysis by the community on our openDAP or LAS (very easy click-and-go access) servers:
