Forests: methane sinks or methane sources?

Forests are not a uniform methane sink because soils, stems, and canopies can act as methane sources or sinks depending on local conditions.

• Why it matters: Component-based approaches have limitations, leaving uncertainty in accurately quantifying net forest CH 4 exchange and the resulting climate feedbacks.
• What they did: The work synthesizes emerging evidence and argues for integrated observational-modeling frameworks rather than treating soils, stems, and canopies separately.
• The result: Integrated observational-modeling is advocated to better quantify net forest CH 4 exchange and improve estimates of climate feedbacks linked to forests.
