The US is facing an unusually cold winter, marked by multiple Arctic air blasts, making it the coldest January since 1988 for the Lower 48. This cold weather stands in stark contrast to global warming, where January was the warmest on record worldwide. Experts attribute the cold to a disrupted polar vortex and persistent weather patterns. Though this season seems extreme, it's indicative of a warming climate, where while winter temperatures are rising due to fossil fuel emissions, memories of colder seasons linger, creating a confusing weather narrative.
Scientists say it's being caused by a misbehaving polar vortex combining with a key weather pattern that seems to be stuck in place, leading to extreme cold.
Zeke Hausfather noted that when experiencing a chilly season, it's somewhat jarring, as there has been no location in the U.S. where the coldest day has gotten colder over the last 50 years.
