these feedbacks ensure that the North Pole warms at a faster rate than the equator

While negative feedback loops encourage stability by pushing a system towards equilibrium,positive feedback loops destabilize it by enabling larger and larger deviations.And the recently increased impact of positive feedbacks may have consequences far beyond the Arctic.On a warming planet,these feedbacks ensure that the North Pole warms at a faster rate than the equator.The reduced temperature differences between the two regions may lead to slower jet stream winds and less linear atmospheric circulation in the middle latitudes,where most of the world's population lives.
