Abstract
The Great Green Wall (GGW) is a multibillion-dollar African initiative to combat desertification in the Sahel. However, the potential climate impacts of the most recent GGW plan on northern Africa have not yet been adequately evaluated, raising concerns about unforeseen climate ramifications that could affect stability in northern Africa and undermine the goals of the initiative. Using a high-resolution (∼13 km) regional climate model, we evaluate the climate impacts of four GGW scenarios with varying vegetation densities under two extreme emission pathways (low and high). Higher vegetation density GGW scenarios under both emission pathways show enhanced rainfall, reduced drought lengths, and decreased summer temperatures beyond the GGW region relative to the cases with no GGW. However, all GGW scenarios show more extreme hot days and higher heat indices in the pre-monsoonal season. These findings highlight the GGW contrasting climatic effects, emphasizing the need for comprehensive assessments in shaping future policies.

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 it
