Climate-driven increase of natural wetland methane emissions offset by human-induced wetland reduction in China over the past three decades.

ABSTRACT: Both anthropogenic activities and climate change can affect the biogeochemical processes of natural wetland methanogenesis. Quantifying possible impacts of changing climate and wetland area on wetland methane (CH₄) emissions in China is important for improving our knowledge on CH₄ budgets locally and globally. However, their respective and combined effects are uncertain. We incorporated changes in wetland area derived from remote sensing into a dynamic CH₄ model to quantify the human and climate change induced contributions to natural wetland CH₄ emissions in China over the past three decades. Here we found that human-induced wetland loss contributed 34.3% to the CH₄ emissions reduction (0.92 TgCH₄), and climate change contr
