If the Earth is warming, why does it still get so cold? When winter comes in the north, the Sun goes down over the Arctic and the North Pole. That region cools. It might take a little longer to cool than it did when we had less carbon dioxide, but it, still, gets cold. The cold region becomes isolated as a river of air, the jet stream, strengthens around the edge of a cold pool. If that cold pool, then, gets pushed away from the Arctic and settles over, say the United States, for a while we experience periods of very cold weather.
