A blast of frigid Arctic air has descended into the United States, causing temperatures to plummet but not break records. This cold air outbreak, known as the polar vortex, is occurring more frequently due to a warming world. The jet stream's unusual dip from the Pacific Northwest to the Southeast is causing the cold snap, with temperatures well below average in the eastern half of the country. Climate experts attribute these polar vortex disruptions to climate change, as the Arctic warms faster than the rest of the world, impacting weather patterns. Despite occasional cold outbreaks, global temperatures continue to rise, highlighting the complex relationship between climate change and extreme weather events.
