State of play: Nonprofit climate research and communications organization Climate Central examined 55 years of U.S. temperature data for 241 cities and found that the meteorological spring season of March through May has warmed by a national average of 2.4°F.
Zoom in: Nashville has seen average seasonal temperatures spike by 2.7°F since 1970.
Between the lines: The spring warming in the U.S. is taking place in tandem with increasing temperatures around the world due to human emissions of greenhouse gases from burning fossil fuels such as coal, oil and gas.
