This class is designed to provide students an overview of international efforts to address climate change as well as legislative, executive, and legal actions in the U.S. to reduce greenhouse gas emissions. We will explore the economic, psychological, and other hurdles that stand in the way of solutions to climate. Students will be asked to critically analyze a multitude of approaches that have been identified, and to select and describe in detail the one he/she believes is best suited to advance the goal of 80% greenhouse gas emissions reduction by 2050.
