This fall, faculty from Penn Arts & Sciences, the Wharton School, and the Stuart Weitzman School of Design came together with undergraduates for the 1.5 Minute Climate Lecture series. Every Wednesday in September, crowds of more than 200 people gathered to hear brief lectures on the unprecedented actions needed to avoid the worst consequences of climate change.

The event, spearheaded by Simon Richter, Class of 1942 Endowed Term Professor in the Department of Germanic Languages and Literatures, was created in the spirit of the School’s long-running 60-Second Lectures. The lectures were extended to a minute and a half to recognize the Intergovernmental Panel on Climate Change’s warning that temperature rise must be limited to 1.5°C in order to avoid the most drastic effects of global warming. We are already past 1°C.

This video shows highlights from the lecture series and captures the incredible energy they generated.
