Climate change (CC) is a global environmental problem and source of concern. Effective planning and implementation of CC mitigation and adaptation may arise from knowledge of its causes and effects. Therefore, dissemination of knowledge is highly important for ensuring that the knowledge grows and spreads amongst the various stakeholders and that it is turned into action. The students of today are the leaders and policy makers of tomorrow. They will effectively serve as change agents once their knowledge base has been well established. This study provides analysis of graduate students' level of knowledge of CC, its nature, causes, effects, mitigation, and adaptation. The study population was 57 agricultural science master's students in the Faculty of Agricultural Sciences in Jarash University, Jordan, and the sample consisted of 50 of those students. The study used online test as the knowledge assessment and data collection tool. Frequency distribution analysis uncovered that the sample students possess high level of general knowledge of CC, moderate level of knowledge of mitigation of CC, and high level of knowledge of adaptation to CC. As to the three investigated facets of general knowledge of CC, these students have high levels of knowledge of the nature and the effects of CC and moderate level of knowledge of its causes. These findings contribute to understanding of students' knowledge achievements and gaps and of the need for curricular reform in terms of structure and content that can be shared by agricultural science faculties around the World with similar CC graduate programs.
