Bayesian palaeoclimate model weighting data and code (Python)

This repository contains an implementation of the Bayesian framework for weighting climate model ensembles using palaeoclimate proxy data, applied to Arctic sea ice as reported in Fu et al. (2026).

All model and proxy data required to reproduce the primary of the study are included here. For details on the data and their sources, as well as the weighting scheme itself, please refer to the publication and the references therein.

We welcome further application of this framework; when using it, please cite the original publication.
