Excerpt from article.

“The potential vortex shift in response to persistent sea-ice loss in the future, and its associated climatic impact, deserve attention to better constrain future climate changes,” they conclude.

“Unfortunately, researchers will have plenty of opportunity to explore this link this winter, with the temperature around the North Pole 36 degrees Fahrenheit (20 degrees Celsius) warmer than it should be right now, and the ice sheets struggling to freeze up.”

Naturally my explanation does not count for anything.
