As the northern parts of North America experience some extreme low temperatures it's interesting to consider just how cold our planet can be in places. Of course it's also important to recognize that these temporary, localized deep freezes in the US and Canada also come against a backdrop of indisputable global warming. Indeed, the mechanism for chilling lower latitudes than normal is the relative weakening of atmospheric flows that otherwise help separate polar cold air from the rest of the planet. That weakening is directly attributable to changes brought about by global warming and anthropogenic greenhouse gases.
