Monitoring of methane in soil of German forests for the last 10-24 years found that drier and warmer conditions led to greater penetration of methane into the soil and faster breakdown of methane by soil bacteria. The rate of methane uptake increased by 3% from 1998 to 2022.

Forest soils increasingly extract methane from the atmosphere, long-term study reveals
Forest soils have an important role in protecting our climate: They remove large quantities of methane—a powerful greenhouse gas—from our atmosphere.University of Göttingen (Phys.org)

Just a note because I had misunderstood it first:
"Our analysis shows an increase in CH4-uptake of 3% *per year* on average."
Finally, not so bad news! I mean, it still shows that ecosystems are massively affected by climate change, but since until now almost all feedbacks loops we discovered were positive (=self-enhancing, like thawing permafrost reinforcing climate change).
Before opening a bottle of champagne (or a cup of teas, whatever you like): Not sure how this decrease in soil methane emissions stands in comparison with stuff like reduced plant growth because of changing weather and changes in soil organic matter dynamics (i. e. increased mineralization).
Has anybody numbers/estimates at hand for comparison?
PD: we still need #degrowth and a transition to #agroecology
