New perspectives on temperate inland wetlands as natural climate solutions under different CO2-equivalent metrics
Bibliographic record
Abstract
Abstract There is debate about the use of wetlands as natural climate solutions due to their ability to act as a “double-edge sword” with respect to climate impacts by both sequestering CO2while emitting significant amounts of CH4. We used CO2-equivalent metrics to assess the net flux of greenhouse gases from wetlands on a comparable basis. Three CO2-equivalent metrics were used to describe the relative radiative impact of CO2and CH4—the conventional global warming potential (GWP) that looks at pulse GHG emissions over a fixed timeframe, the sustained-flux GWP (SGWP) that looks the sustained GHG emissions over a fixed timeframe, and GWP* that explicitly accounts for changes in the radiative forcing of CH4over time (initially more potent but then diminishes after a specific period)—against model-derived mean temperature profiles. GWP* most closely estimated the mean temperature profiles associated with net wetland GHG emissions. Using the GWP*, intact wetlands serve as climate solutions. However, restored wetlands only serve as natural climate solutions for mid-century net-zero carbon emission initiatives if effective strategies are implemented to control CH4fluxes.

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.
