How do we educate for emergency? Millions of students are headed back to school this week. My teaching starts too; I am en route to Arizona for the opening colloquium of the semester in a low-residency program, sitting in a jet and emitting more carbon dioxide into the atmosphere in a two-hour flight than a person in some poor countries does in a year. It leads me to think about education and ignorance, and specifically about what makes for good education in a time of emergency. What do today’s students need to learn in order to respond to the ecological crisis?
