Abstract
Warming world analogue model diagnosis of total cloud amount trends is reviewed. Using cloud amount records for the continental U. S. A. (published), Canada, including parts of the Arctic (in preparation), Europe (published) and the Indian sub-continent (new results), cloudiness changes have been analyzed in the context of the analogue model which compares records of two contrasting twenty year periods. Cloud amount is found to increase over practically the entire U. S. A., Canada, most of the Indian sub-continent, and parts of Europe in all seasons. These results have been derived for a wide range of climates and considerably strengthen the more tentative findings of Henderson-Sellers (l986a, b) and MeGuffie and Henderson-Sellers (1987) that total cloud amount increases in a warming world. On the other hand, the record of total cloud amount since the 1900s has suffered from changes in observing and reporting practice from differing emphasis on observer training and from time sampling biases. These aspects of the record are considered here in detail. Moreover it must be recognized that the historical record reviewed here is land-based only, contained within the northern hemisphere and excludes many areas especially the tropics and equatorial regions. The results achieved so far could indicate that the current real-world transient experiment in which CO 2 and temperatures are increasing includes a negative feedback on increasing temperatures due to increasing cloud amount. However the very restricted area considered also means that the apparent trend may be much less than global. Specifically results are not inconsistent with numerical model predictions of storm tracks shifted poleward in doubled CO 2 experiments. At the least, the predictions of cloud changes made by numerical models could be re-examined in the light of the results described here.

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
