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

💡 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.
