Which effect does increased atmospheric carbon dioxide exert via radiative forcing on permafrost regions?

💡 Explanation

When CO2 increases, radiative forcing traps more heat, which accelerates permafrost thaw because ice melts contributing to decomposition releasing high quantities amounts Greenhouse Gases back into the atmosphere forming a Positiv Feedbackloop which therefore triggers increased methane release, rather than decreased precipitation, increased albedo, or reduced decomposition, linked to completely different mechanisms.
