Climate change from the previous period there have been, in recent decades, due to the in tensification of human activities have created in ternation alconcern and its effect on agricultural production worldwide. In this study ,the combined data (panel) and the dynamic OLS (DOLS) was used to estimate. The results showed that temperature until the temperature return sover the long term, the positive impact and it has had a negative effecton the performance of cotton, the threshold temperature of 17.29°C, The weather temperature in long-term elasticity of 0.21% is obtained, ie, at constant average annual temperature averages if the other conditions of apercent increase, the average performance of cotton during the period under review 0.21% increase .In short model coefficient estimates ecm (-1), equivalent to -0.46 obtained show that in the period 0.46 amoun to fvariables to converge to wards the long-run equilibrium. Finally,it is suggested to prevent temperature rise of human in terferencein nature (such as destroyingpastures and forests) preventandto dealwith increasing temperatureis recommendedvarietiesresistant totemperatureor changecropping patternshould be used.
