Abstract

fetched live from OpenAlex

ontreal Protocol, the multilateral treaty to protect the ozone layer, has been a successful environmental agreement. But an impasse over restricting the use of extremely potent greenhouse gases marred the Protocol’s 25th anniversary celebrations on September 16, 2012. These gases, called hydrofluorocarbons (HFCs), emerged as the coolant of choice after the Protocol banned ozone-depleting chemicals used in the refrigeration and air-conditioning sectors. While developed countries seek to amend the Montreal Protocol to control the use of HFCs, developing countries contend that the agreement does not and cannot have the mandate to regulate greenhouse gases. They say the amendment proposal is a ploy of rich nations to sell HFC replacement technologies and mint money. Produced mostly in developed countries, HFCs replaced chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) that were phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer. HFCs pose no harm to the ozone layer because, unlike CFCs and HCFCs, they do not contain chlorine that depletes the ozone layer. But HFCs are super-greenhouse gases with an extremely high global warming potential. This means they are capable of trapping enormous amounts of infrared radiations in the atmosphere and can cause a greenhouse effect a thousand times stronger than carbon dioxide. The debate: Developed countries want to discuss HFCs under Montreal Protocol, developing countries under climate negotiations It’s been four years since the issue of bringing HFCs under the Protocol’s ambit was raised. Developed countries say that since the rise in the emission of super-greenhouse gases is a consequence of the phasing out of CFCs and HCFCs under the Montreal Protocol, the same agreement should monitor them. 2 0

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.
