Wetlands act as an important natural source of global methane (CH 4 ). The emission rate wetland CH is jointly affected by climate change, carbon dioxide (CO 2 ) fertilization, and distribution. In this study, we implemented a module into the Yale Interactive Biosphere (YIBs) model to quantify spatiotemporal variations emissions in 2001–2020. Site-level validations showed that YIBs reasonably captures seasonality magnitude at 28 out 33 sites with significantly positive correlations low relative biases. On scale, predicts annual mean 147.5 Tg yr −1 2000–2017, very close estimate 147.9 from ensemble 13 process-based models. Global trend 0.74 −2 past decades, leading increase 7.4 (5.2%) 2008–2017 than 2000–2009. Climate change CO fertilization accounted for over 70% changes. Among them, impact grew steadily became dominant factor after year 2008. most significant changes were located tropical regions following perturbations temperature drives ecosystem productivity.

Abstract Natural climate solutions can mitigate change in the near-term, during a climate-critical window. Yet, persistent misunderstandings about what constitutes natural solution generate unnecessary confusion and controversy, thereby delaying critical mitigation action. Based on review of scientific literature best practices, we distill five foundational principles (nature-based, sustainable, climate-additional, measurable, equitable) fifteen operational for practical implementation. By adhering to these principles, practitioners activate effective durable solutions, enabling rapid wide-scale adoption necessary meaningfully contribute mitigation.

This literature review synthesizes the role of soil moisture in regulating carbon sequestration and greenhouse gas emissions (CS-GHG). Soil directly affects photosynthesis, respiration, microbial activity, organic matter dynamics, with optimal levels enhancing storage while extremes, such as drought flooding, disrupt these processes. A quantitative analysis is provided on effects CS-GHG across various ecosystems climatic conditions, highlighting a "Peak Decline" pattern for CO₂ at 40% water-filled pore space (WFPS), CH₄ N₂O peak higher (60–80% around 80% WFPS, respectively). The also examines ecosystem models, discussing how dynamics are incorporated to simulate nutrient cycling. Sustainable management practices, including conservation agriculture, agroforestry, optimized water management, prove effective mitigating GHG by maintaining ideal levels. further emphasizes importance advancing multiscale observations feedback modeling through high-resolution remote sensing ground-based data integration, well hybrid frameworks. interactive model-experiment framework emerges promising approach linking experimental model refinement, enabling continuous improvement predictions. From policy perspective, shifting focus from short-term agricultural productivity long-term crucial. Achieving this shift will require financial incentives, robust monitoring systems, collaboration among stakeholders ensure sustainable practices effectively contribute climate mitigation goals.

Natural methane (CH4) emissions from aquatic ecosystems may rise because of human-induced climate warming, although the magnitude increase is highly uncertain. Using an exceptionally large CH4 flux dataset (~19,000 chamber measurements) and remotely sensed information, we modeled plot- landscape-scale wetland Prairie Pothole Region (PPR), North America's largest complex. Plot-scale were driven by hydrology, temperature, vegetation, size. Historically, PPR largely dependent on total extent. However, regardless future extent, are predicted to two- or threefold 2100 under moderate severe warming scenarios, respectively.

Freshwater wetlands have a disproportionately large influence on the global carbon cycle, with potential to serve as long-term sinks. Many of world's freshwater been destroyed or degraded, thereby affecting carbon-sink capacity. Ecological restoration degraded is thus becoming an increasingly sought-after natural climate solution. Yet time required revert wetland from source sink remains largely unknown. Moreover, increased methane (CH4) and nitrous oxide (N2O) emissions might complicate benefit that may represent. We conducted meta-analysis evaluate benefits in terms net ecosystem greenhouse gas balance. Most studies (76 %) investigated peatlands (bogs, fens, peat swamps) northern hemisphere, whereas effects non-peat (freshwater marshes, swamps, riparian wetlands) remain unexplored. Despite higher CH4 emissions, most restored (77 all were sinks, (69 sources. Conversely, similar across restored, wetlands.
