The climate change issue is a new and complex information for the most farmers. Thus, this research describes the farmer belief, variable of communication, which affects the farmer belief, and model of the farmer belief towards climate change. The 48 farmers from an area that is vulnerable of climate change effect are taken via a survey. Chi-squared statistics and logistic model are tested in the data. The result shows that most of the farmers do not believe that climate changes. The belief relates to the literacy, variation of the information source, intensity of application and achievement to seek the climate change information. If the variation of the information source increases, the chance to believe climate change is two times higher. It is suggested that the capacity of mastery of climate change information from the information sources has to be increased, for example, education and training of climate and dissemination of climate change information via various media, which are ensured that the information is correctly delivered to the farmers.
