A Story between Success and Challenge - 20th Anniversary of the Montreal Protocol
Bibliographic record
Abstract
When the Montreal Protocol on Substances that deplete the Ozone Layer was signed by twenty-four countries and the European Community in September of 1987, it was hailed as a milestone in international environmental diplomacy. And indeed, the Montreal Protocol, now ratified by more than 190 nations, still represents a major political and diplomatic achievement in the international effort to protect stratospheric ozone. Designed to control the production and consumption of ozone-depleting chemicals, the Protocol provides for a gradual phase-out of chlorofluorocarbons before irreversible damage is done to the Earth's ozone layer. Therefore, the Montreal Protocol, the foundation for this process, stands as an extraordinary and even spectacular success story. Unfortunately, there is still no room for complacency and the Montreal Protocol's work to protect the ozone layer is far from done. In 2006 scientists recorded nearly the largest ozone hole ever over Antarctica, and new data indicates that the recovery of the ozone layer above Antarctica will be delayed by fifteen years, with a return to pre-1980 levels not occurring until 2065. Ozone layer recovery at mid-latitudes is also delayed and will not return to pre-1980 levels until 2049. The fact remains that a great deal of additional action will be essential to ensure that the ozone layer remains safe for current and future generations. At present, some serious problems are undermining the successful protection of the ozone layer. Effective implementation faces several main challenges - for example, illegal trade in ozone-depleting substances. The role of developing countries is still a major concern and in regard to global warming it is important to emphasise the linkage between Montreal and the Kyoto Protocol. This year the Montreal Protocol is celebrating its 20th Anniversary. It represents a good opportunity to look back at all measures already taken by parties to prevent further ozone depletion and to acknowledge obtained achievements. But on the other hand, this anniversary is an even better opportunity to observe that the Protocol's work is far from done.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
