Abstract
Abstract Climate breakdown driven by massive volcanic eruptions was the likely cause of the terrestrial Permian–Triassic mass extinction (ca. 252 Ma). However, establishing the relationship between climate factors and terrestrial ecosystem responses is difficult. Furthermore, it is unclear if the pattern and timing of the terrestrial ecosystem crises are consistent across different regions. Our integrated paleontology and geochemistry study indicates that the onset of the terrestrial crisis in North China preceded that in South China by at least 300 k.y. Geological and Earth system modeling suggest that lethal heatwaves and aridity, along with enhanced climate seasonality, were caused by higher atmospheric CO2. The onset of these environmental changes varied regionally and were likely responsible for the diachronous terrestrial crisis. Our results indicate that, rather than a globally synchronous event, cumulative regional extirpations ultimately resulted in a global terrestrial extinction.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
