United States
This past winter was highlighted as one of the warmest on record in the US, with significant contrasts between warm temperatures in the West and cold in the East. It points to climate change impacts, with the fastest-warming season now being winter in many places.
The claims regarding recent winter temperature records across various regions in the US are supported by evidence from multiple sources, including CNN and other reliable sources. The Lower 48 states experiencing the second warmest winter on record and the Western US having its warmest winter are both confirmed by the cited evidence. Salt Lake City also recorded its warmest winter, as evidenced by data from the National Weather Service. The claim about the smallest cold pool does not match relevant evidence and should thus be approached with caution, while the assertion that winter is the fastest-warming season in the US aligns strongly with climatological data analyzed by Climate Central.
