The gradual warming of the atmosphere, depending on the result of climate change, is creating significant impacts on agriculture to increase the number and frequency of extreme weather events. This affects food security, arises in development and international trade. In the fight against climate change and its impact on agriculture, implemented jointly by the international climate mitigation and adaptation policy circles are carried out. In this study it is aimed to investigate the impact of climate change on agriculture sector in Turkey for the period 1980-2013. In order to investigate the possible effects of climate changes on agriculture sector the relationship between agricultural productivity, CO2 emissions, temperature, rainfall and agricultural GDP was estimated by using the ARDL methodology. The empirical results show that existence of a positive and significant relationship between agricultural productivity, rainfall and agricultural GDP. However, the impact of CO2 emissions on agricultural GDP is estimated to be negative and statistically significant. In addition, temperature changes negative impacts on agriculture sector findings which were obtained. The findings in this paper support that the climate change negatively affect agriculture sector.
