This study examines the exposure of Thai youths to media information on global warming, the relationship between exposure to global warming information and awareness of global warming, and the relationship between that awareness and lifestyle activities that contribute to global warming. A focus group of eight Thai youths provided information that was used to construct a questionnaire, which was administered to 2,500 Thai youths. In-depth interviews with academics and mass communication experts were also conducted. The study took place from early 2008 to mid-2009 in various parts of Thailand. Analysis of the questionnaire responses indicate that most of the Thai youths in the study obtained information about global warming primarily from television; often, however, they do not understand the information.
