Which risk sharply increases along Arctic pipeline routes when ambient temperatures rise above freezing?

A)Compromised structural integrity through thaw weakening✓

B)Increased methane hydrate formation offshore

C)Accelerated corrosion from concentrated sea salts

D)Disrupted migratory patterns near access roads

💡 Explanation

Pipeline routes on permafrost are vulnerable to displacement via solifluction because soil liquefies when temperatures exceed 0°C (32°F); therefore, the structural integrity risk increases rather than methane production or corrosion rates.
