As the young generation need to adopt sustainable lifestyle changes to bring down climate change, this study was conducted to assess the awareness about climate change among high school children in urban areas of Mysuru. Methods: A cross-sectional study was conducted among high school students in 2018–19. The schools were selected by the simple random method and students from each school were recruited by Population Proportional to Size method. Descriptive statistics like percentages were applied and appropriate inferential statistical tests were done for association. Results: Among the students interviewed, 69.5% were aware of climate change and 61.9% were aware of the health impacts of climate change. 63.3% were aware of global warming and only 51% were aware of the greenhouse effect. Only 10% of study participants had good knowledge about climate change. 32.9 % of students had a satisfactory knowledge, 24.3% had average knowledge and 32.9% had only poor knowledge about climate change. Conclusion: The awareness of climate change is low among high school students of urban areas of Mysuru. Only a minority of students have good knowledge about climate change.
