How can global warming cause large parts of the U. S. to experience extremely cold temperatures?​

Temperature fluctations is what you wanna know.

Explanation:

Sometimes the air pressure is higher in the south so the warmer air pushes north, and keeps the really cold Arctic air in the Arctic. This is called the “positive phase” of the Arctic Oscillation. Other times the air pressure is higher in the Arctic so the cold air moves south.
