Canada has experienced its coldest December temperature in half a century, with readings plunging to –55.7°C. The extreme cold wave has disrupted transportation, frozen critical infrastructure, and significantly increased health risks such as frostbite and hypothermia.
Authorities have issued urgent advisories, encouraging residents to remain indoors when possible and to take extra precautions if travel is unavoidable. Meteorologists attribute the unusually severe conditions to shifts in Arctic weather patterns and disturbances in the polar vortex, which have allowed frigid air to move farther south than usual.
