Abstract
The frozen lands of the north are an unforgiving place for humans to live. The Inuit view of the cosmos is that it is ruled by no one, with no gods to create wind and sun and ice, or to provide punishment or forgiveness, or to act as Earth Mother or Father. Amid those harsh landscapes, belief is superfluous, and only fear can be relied on as a guide. How could such a world begin, and end? In Nordic mythology, in ancient times there used to be a yet greater kingdom of ice, ruled by the ice giant, Ymir Aurgelmir. To make a world fit for humans, Ymir was killed by three brothers—Odin, Vilje, and Ve. The blood of the dying giant drowned his own children, and formed the seas, while the body of the dead giant became the land. To keep out other ice giants that yet lived in the far north, Odin and his brothers made a wall out of Ymir’s eyebrows. One may see, fancifully, those eyebrows still, in the form of the massive, curved lines of morainic hills that run across Sweden and Finland. We now have a popular image of Ymir’s domain—the past ‘Ice Age’—as snowy landscapes of a recent past, populated by mammoths and woolly rhinos and fur-clad humans (who would have been beginning to create such legends to explain the precarious world on which they lived). This image, as we have seen, represents a peculiarly northern perspective. The current ice age is geologically ancient, for the bulk of the world’s land-ice had already grown to cover almost all Antarctica, more than thirty million years ago. Nevertheless, a mere two and a half million years ago, there was a significant transition in Earth history—an intensification of the Earth’s icehouse state that spread more or less permanent ice widely across the northern polar regions of the world. This intensification— via those fiendishly complex teleconnections that characterize the Earth system—changed the face of the entire globe. The changes can be detected in the sedimentary strata that were then being deposited around the world.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
