Not for the first time in recent years, Europe has descended into a deep freeze while the Arctic experiences record high temperatures, leaving scientists to ponder the role global warming may play in turning winter weather upside down.
The reversal has been dramatic.
A Siberian cold front has spread sub-zero temperatures across Europe, carpeting southern cities and palm-lined Mediterranean beaches with snow.
On Sunday, meanwhile, air temperatures at the North Pole — which won’t see the Sun until March — rose above freezing.
“In relative terms, that’s a 30 C (54 degrees Fahrenheit) temperature anomaly,” Robert Rohde, lead scientist at Berkeley Earth in Washington, tweeted.
