Which risk increases when Arctic sea ice cover declines?

💡 Explanation

Increased Arctic warming reduces the temperature difference between the Arctic and mid-latitudes causing a weakening of the polar vortex; the *Rossby wave propagation* increases, therefore, causing greater meanders in the jet stream leading to more extreme weather, rather than stable conditions.
