← GeographyWhich outcome results when increased summer temperatures affect discontinuous permafrost?
A)Acceleration of thermokarst lake formation✓
B)Increased albedo due to melting ice

D)Expansion of boreal forest ranges
💡 Explanation
Thermokarst lakes form because permafrost thaw increases soil instability through thaw subsidence. This is positive feedback, rather than decreasing methane which would slow climate change, therefore A is correct.
