A significant Arctic cold wave, attributed to disruptions in the polar vortex, has plunged much of the United States and Europe into severe winter conditions. Meteorologists report record-low temperatures, heavy snowfall, and widespread disruptions, prompting warnings from authorities. The polar vortex, a band of strong winds that typically confines cold air to the Arctic, has weakened, allowing frigid air to spill southward. This phenomenon not only affects daily life but also raises concerns about energy demand and infrastructure resilience.
