Model Diagnostics of Variations in Methane Emissions by Wetlands in the Second Half of the 20th Century Based on Reanalysis Data

摘要

This work is dedicated to model assessments of variations in methane emissions into the atmosphere by terrestrial ecosystems for different regions and the Earth as a whole based on variations in the near-surface temperature of the atmosphere and precipitation derived from the reanalysis data for the second half of the 20th century. The statistically significant general trend of increase in methane fluxes from bog systems into the atmosphere under global warming is diagnosed.
