Abstract

fetched live from OpenAlex

Climate warming at high latitudes may be contributing to the increase in areal extent of terrain disturbance associated with thawing permafrost. To evaluate change over time we analyzed historical temperature records and mapped retrogressive thaw slumps in the Mackenzie delta region using 1950, 1973 and 2004 aerial photographs. Here we show that rates of retrogressive thaw slump activity from 1973–2004 were significantly greater than during the preceding period (1950–1973) and suggest that these changes have occurred in response to a significant warming of annual and summer air temperatures during the period of record. In rolling, ice‐rich terrain, the rate of thaw slump activity can be expected to increase with continued climate warming. The impacts of slumping on landscape evolution and soil and lake chemistry will likely magnify the direct effects of warming on terrestrial and aquatic ecosystems.

Full frame distilled prediction

Teacher imitation

Not 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.
