Warming at the poles reduces the temperature contrast between the poles and the tropics, which weakens the subpolar jet streams and makes them more likely to meander, making blasts of bone-chilling cold into the mid-lattitudes and extreme mid-winter thaws of the sort that happened this February more common.
