Which risk increases when cryospheric melting destabilizes thermokarst landscapes?

💡 Explanation

Increased risk of thermokarst destabilization causes the release of trapped methane deposits; this is the albedo feedback mechanism, because the exposed permafrost thaws and releases methane rather than keeping the methane frozen, thus decreasing carbon capture.
