Answer 1

It creates more instability at the poles which cause more extremes in Temps. The polar vortex becomes more bean shaped when it should be more circular.

Because of this bean shape, in the northern hemisphere, we warm our cooler polar air all at once in the spring instead of it keeping our summers mild. This cycles gets progressively worse as the ice caps melt.
