As our planet’s climate changes, it is imperative to understand the basic structures of the earth system and our connections to these, past, present, and future. The goal of this course is to help students develop an integrated understanding of climate change, linking the fundamental science – from the microscopic to the global scale – to human actions and possible futures. This course brings together approaches from environmental science, social sciences, history, and policy. Beyond providing basic climate and environmental literacy, we will also explore current and projected impacts of change, including changes to human life and biodiversity as well as other physical and biological systems. The course is divided into three units: 1. Science: what are the chemical and physical drivers of our changing climate, and what are the biological, health and environmental implications so far. 2. Impacts: how human activity has affected environments and climate so far and how climate change is currently impacting society, nature, agriculture, health, cities, and the most vulnerable communities. 3. Solutions: the roles of policy, business, agriculture, planning, and personal choices. The course is open to undergraduate students of all disciplines. While the reading and weekly assignments will be specific to the module, students may define a capstone project that reflects their academic interests.
