Abstract

fetched live from OpenAlex

In an era of rapid climate change, the need for reliable information to support adaptation has never been greater. Changes resulting from warming temperatures and shifting precipitation patterns are influencing snowmelt dynamics, freeze-thaw cycles and basin response. These shifts may transform Canada’s environmental systems in profound and unprecedented ways. The Global Water Futures modelling research was developed to address these evolving challenges, providing insights into how Canada’s major river basins may respond to these changes. This work focuses on the pan-Canadian application of the MESH land-surface hydrology model across the Yukon, Fraser, Columbia, Mackenzie, Nelson, Churchill, Great Lakes-Saint Lawrence, and Saint John Basins, covering more than 5 million square kilometres. The model simulations integrate bias-corrected, downscaled climate projections to explore future scenarios. We detail the innovative workflows and tools developed for this research and present key findings on glacier retreat, permafrost thaw, and shifting river flow regimes. These results underscore the critical need for adaptive, forward-thinking water resource management to build resilience and strengthen the adaptive capacity of Canada’s watersheds.

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.
