Kevin Petty, director of science and forecast operations for The Weather Company, explained the difference between these two terms in an article published by the Weather Channel: Global warming is another term that causes some confusion. While the data shows that average global temperatures have been climbing for decades, that does not mean that wintry weather is a thing of the past. In fact, the cold snap in the United States in February 2021 may actually show the impact of climate change: PBS NewsHour reporter Amna Nawaz talked to Dev Niyogi, a professor at the Department of Geological Sciences at the University of Texas, Austin, about this issue:
