MADISON, Wis. (WMTV) – With temperatures rising across the state, experts are concerned about how it is contributing to climate change. According to UW Madison Atmospheric and Oceanic Science Department Professor Jonathan Martin, September to October of 2024 is the second warmest it’s been since 1938. Martin studies the world’s air flow and said climate change is partially caused by warm winds eroding ice in the north and causes warmer temperatures in Wisconsin.
