Abstract

Worldwide, China is home to the fourth largest combined area of natural wetlands. A recent study provided a synthesis of its carbon budget. However, based on our experience of observing and simulating CH4 emissions from natural wetlands, as well as evidence in the literature, we suggest the results to be an overestimation of the CH4 release from China's marshlands, and here are the two reasons why: an overestimation of the extent of China's marshlands and an overestimation of the CH4 emission rates from the Tibetan Plateau.
