Join us for weekly sessions on environmental topics presented by University of Illinois Extension's Energy & Environmental Stewardship Team! These webinars will both provide new information on natural resources and help you learn how to make small changes in your lifestyle to have a positive impact on the environment. From lawn care, native plants, and managing home waste to understanding coyote behavior and atmospheric optics, there is never a shortage of new things to learn about your everyday environment.

In this session, Extension Educator Duane Friend will explain such things as why we see a blue sky, why twilight is longer near the poles, sun dogs, halos, mirages, and other atmospheric optics.

Registration is free!
