This document provides an overview of Section 1 of a course on Climate Change and Sustainability. The Section contains 4 learning resources: 1) a video interview with Professor William C. Clark about key concepts of climate change and sustainability, 2) a video on why climate change matters that discusses divides between developed and developing countries, 3) a presentation of an online collaborative glossary to define technical terms, and 4) a self-assessment quiz to test comprehension. The overall goals are to introduce fundamental issues and promote a shared understanding of language in the multidisciplinary field.
