Abstract

fetched live from OpenAlex

This paper addresses problems in calculating primary energy discovered during an analysis of the 40 scenarios of world primary energy demand prepared by working group III of the Intergovernmental Panel on Climate Change (IPCC). Problems in calculating primary energy arise because of: inconsistent use of efficiency of conversion values for calculating primary energy from final energy; unsubstantiated low values for nuclear primary energy; omission of the problems caused by the characteristics of wind and solar primary energy and limits to hydropower; inclusion of overestimated electricity in final energy; and inconsistent use of the various scales for measuring primary energy. The primary energy given misrepresents the final energy that is the basis of each scenario. Consequently, the anthropogenic emissions derived from the primary energy are also misrepresented, thereby possibly causing problems with the results of climate models that use these emissions. It is recommended that the IPCC scenarios are reviewed and the questions raised in this paper resolved during construction of the next set of scenarios currently being considered.

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.
