To fill in a curriculum gap in the BS Environmental Science degree program, in 2018, Dr. Wang created a new course called "Climate Change and Society (GEOL-G477)" for junior/senior level students in the Department of Earth Sciences. Because climate change is a well-discussed topic, there are plenty of online resources available to cover di erent aspects of the topic. Therefore, instead of relying on expensive textbooks, the nominee searched and decided to use two Open Educational Resources for this course.
