This document provides a study guide for a session on climate change for an adult Christian education program. The session aims to help participants understand how the atmosphere regulates the Earth's climate, why the climate is warming due to increased greenhouse gases, and some of the potential effects of climate change. It includes an activity where participants simulate the greenhouse effect and discusses how increased CO2 is trapping more heat. The study guide then prompts groups to brainstorm ways climate change could impact weather, oceans, plants/animals and human communities.
