Short summary
We studied how rain and snow are changing across the Arctic as the climate warms. Using weather data from land, ocean, and a global climate dataset, we found that more of the Arctic’s precipitation is falling as rain instead of snow, especially in summer and in the Atlantic region. These changes are not always due to more total precipitation, but rather less snowfall. This shift could affect Arctic ecosystems, infrastructure, and future climate patterns.
