North America Colder than Planet Mars

The cold snap gripping many parts of the United States and Canada has brought record-breaking icy temperatures lower than the surface of Mars.
The chill, which has been named the Polar Vortex, has brought in frigid air from the Arctic. The town of Embarrass, Minnesota recorded the lowest temperature in the U-S on Tuesday at minus thirty-seven degrees Celsius. In Canada, Toronto's Pearson Airport temporarily halted ground operations because of equipment freezing and concerns for the safety of airport personnel. Wind chill factors as low as minus fifty degrees Celsius plunged the western Prairies region into a deep freeze.
