The Program on Climate Change (PCC) held its third annual Spring Symposium on Saturday, April 27, 2019. Over the span of lively morning and early afternoon sessions, 17 students and postdoctoral researchers shared their climate-related research, education, and outreach work through a full program of talks and posters. These presentations represented a variety of perspectives on climate, drawing from observation and modeling of physical and ecological processes on scales ranging from the hyperlocal to global, as well as insights from policy, industry, and philosophy.
