Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect wetland C pools and fluxes are complex and dynamic, making measurements of wetland C challenging. Over decades of research, many observational, experimental, and analytical approaches have been developed to understand and quantify pools and fluxes of wetland C. Sampling approaches range in their representation of wetland C from short to long timeframes and local to landscape spatial scales. This review summarizes common and cutting-edge methodological approaches for quantifying wetland C pools and fluxes. We first define each of the major C pools and fluxes and provide rationale for their importance to wetland C dynamics. For each approach, we clarify what component of wetland C is measured and its spatial and temporal representativeness and constraint

This week we re pleased to highlight a paper by Sergei Samoilenko and John Cook, the latter name likely familiar to many as Dr. Cook is the founder of Skeptical Science. Published in Climate Policy, Samoilienko & Cook s Developing an Ad Hominem Typology for Classifying Climate Misinformation codifies, categorizes and analyzes a large sample of ad hominem arguments derived from numerous contrarian blogs and think-tanks, distilling the following key results:
