← GeographyWhich risk increases as rising global temperatures accelerate permafrost thaw?
A)Increased methane release from hydrates✓
B)Decreased albedo amplifying warming
C)Reduced primary productivity in tundra
D)Stabilized carbon sequestration within peat
💡 Explanation
As permafrost thaws, organic material decomposes because microbial activity increases releasing trapped methane hydrates as permafrost melts. Therefore methane release is the risk rather than decreased albedo, reduced productivity or stabilized carbon sequestration are suppressed by permafrost thaw conditions.
