This research aims to conduct a preliminary study on the understanding of the concept of climate change for the first-year postgraduate science education students at Unesa. The purpose of this study is to determine the level of understanding of students’ concepts of climate change and find patterns of sustainable climate change education that are expected to prepare Indonesian people to face the growing issue of climate change through effective teaching. The research subject is 17 postgraduate students of science education for the first semester. The method used is quantitative descriptive. Data were collected through distributing questionnaire instruments about climate change and global warming. The results of the study show that the concepts of climate change and global warming are still something new and interesting for science education students. Most students are not familiar with climate variables. They still have difficulty distinguishing the term climate change, global warming, ozone layer depletion, and the greenhouse effect. The results of this study are used as the basis for constructing sustainable climate change education in Indonesia. Keywords: climate change, patterns of sustainable climate change education, effective teaching
