Abstract

fetched live from OpenAlex

The goal of the Climate System History and Dynamics (CSHD) Program is to improve understanding of the global climate system so as to increase our ability to predict future change in the global environment. Papers in this special issue represent examples of work accomplished during CSHD-Phase 1, which began in 1995 and ended in 1998. This special issue presents the work of ten groups of scientists, including groups interested in the reconstruction of past climate states using geologically derived proxy data and groups interested in the use of models to predict these states, combined in a focused effort to provide a Canadian contribution to the international Paleoclimate Model Intercomparison Project (PMIP). CSHD-Phase 1 primarily focussed on two "time slices:" the last glacial maximum (LGM) of the late Cenozoic (21 ka BP) and the mid-Holocene warm period (6 ka BP).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
