Uncertainty in Climate Change Discourse: An Examination of Regional Canadian Newspapers
Bibliographic record
Abstract
This thesis examines the prevalence and framing of climate change across seven regional Canadian newspapers, with a focus on climate uncertainty, from April 1 to September 30, 2013.Results indicate that climate change and uncertainty are prevalent across Canadian newspapers, and that there is a prevailing discourse.Climate change is primarily framed as a contemporary issue that exists on an international scale.It is often linked to environmental, political, energy, and scientific issues; however, climate change itself is primarily de-contextualized.Climate solutions are especially lacking from the discourse and climate responsibility is either non-existent or related to government.It is thus not surprising that uncertainty within the discourse is primarily about climate action and solutions.Although there are some statistically significant differences between the regional newspapers in regards to spatial framing, climate context, and climate attitude, there does not appear to be any underling spatial pattern therein.v IV.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
