New perspectives on temperate inland wetlands as natural climate solutions under different CO₂-equivalent metrics

S. Ma, I. F. Creed, et al.

This research conducted by Shizhou Ma, Irena F. Creed, and Pascal Badiou explores how temperate inland wetlands can be powerful natural climate solutions, effectively sequestering CO₂ while influencing greenhouse gas emissions. It reveals that preserving these wetlands is not only vital for ecosystem health but also a financially savvy approach to mitigating climate change effects over the next 500 years.

Abstract
This paper investigates the role of temperate inland wetlands as natural climate solutions, considering their capacity for both CO₂ sequestration and CH₄ emission. Using a process-based greenhouse gas (GHG) perturbation model and three CO₂-equivalent (CO₂-e.q.) metrics (GWP, SGWP, GWP*), the study simulates wetland radiative forcing and temperature change over 500 years. GWP* proves most accurate in estimating temperature profiles, indicating that intact wetlands act as net CO₂-e.q. carbon sinks and provide net cooling. Wetland conservation is highlighted as a cost-effective climate solution, while restoration offers both short- and long-term benefits.
