Which geoengineering risk increases within permafrost regions following albedo modification efforts?

💡 Explanation

Albedo modification can warm deeper permafrost layers accelerating the decomposition of organic material; this triggers methane hydrate destabilization because of enhanced microbial activity producing methane, therefore increasing greenhouse gas emissions, rather than decreasing them or affecting tectonics.
