In an analysis of nearly 200,000 Twitter posts from 2012 and 2022, University of Michigan researchers found differences in how pollen season is discussed across political groups. The study connects these differences to views on climate change and how people interpret environmental changes in daily life. In this Michigan News research spotlight, study author Yiluan Song from the U-M School for Environment and Sustainability explains how Twitter users with different political perspectives talk about pollen season and climate change.
